How to avoid physiological diseases when planting andrographis andraeanum indoors?
Usually wild Anthurium andraeanum is attached to trees or rocks or the ground. Its roots absorb not only nutrients from bark stones, but also moisture from moist air, so Anthurium andraeanum likes warm, humid and well-drained environment. The substrate with good drainage should be selected for potted red palm. Families usually use a mixture of peat soil and perlite at 1:1 or grass carbon soil and sand at 2:1, or coconut shell and perlite at 2:1, with a pH value between 5.5 and 6.5. the prepared matrix must be sterilized. The optimum growth temperature is 20-30 ℃, the highest temperature should not exceed 35 ℃, and the lowest temperature is 14 ℃. Freezing injury may occur at any time when the temperature is lower than 10 ℃. The optimum air relative humidity is 20%-80% and should not be less than 50%. Indoor potted plants should be placed in bright places with a certain degree of scattered light, and never put Anthurium andraeanum in a strong direct sunlight environment, otherwise it will produce serious leaf burning phenomenon. According to their habits, the following planting and breeding measures should be taken:
(1) Control the room temperature. Because Anthurium andraeanum is a semi-shady plant, the suitable temperature for the growth of Anthurium andraeanum is between 14 and 35 ℃, and chilling injury will occur when the temperature is lower than 10 ℃; when the temperature is higher than 35 ℃, the plant will also be injured, in this case, water should be sprayed to the plant and its surroundings in time, to a certain extent, when the humidity is very high at high temperature, it will not be so easy to cause injury. Measures such as sprinkling water on the ground should be taken in summer to reduce the room temperature to less than 35 ℃. In winter, if the indoor temperature is lower than 12 ℃, plastic bags and incubators can be used to improve the temperature around Anthurium andraeanum.
(2) maintain relatively high air humidity. This is the key to the maintenance of indoor Anthurium andraeanum pots. We must take all measures to improve the air humidity in the environment of Anthurium andraeanum. Generally, we can put a few cups of water around Anthurium andraeanum, foliar spray (pay attention to do not spray the foliar surface in the evening, be sure to ensure that there are no water droplets on the leaves of Anthurium andraeanum at night), spray water on the ground, and so on.
(3) always keep the leaf surface clean.
(4) adequate supply of fertilizer and water. In spring and autumn, fertilizer and water are usually irrigated once every 3 days, if the temperature is high, the substrate in the basin can be irrigated once every 2 to 3 days according to the dry and wet substrate in the basin, once in 2 days in summer, and once in 5 to 7 days in winter. When applying liquid fertilizer, we can choose the complete fertilizer of nitrogen: phosphorus: potassium at 1:1:1, and the concentration of potash fertilizer should not exceed 250ppm. The purpose of Anthurium andraeanum fertilization is to be rare rather than heavy, eat less and eat more, otherwise it is easy to cause root injury, affect plant growth and directly cause plant death. Anthurium andraeanum likes to be wet (high relative humidity), but the substrate is required to be dry, so watering is best combined with leaching fertilizer, usually spraying water to the leaves and around, in order to increase the relative humidity of the cultivation environment.
(5) Anthurium andraeanum is generally resistant to diseases and insect pests, but attention should be paid to avoid the harm of red spiders, nematodes, cabbage worms, whitefly, thrips, snails, slugs, termites, moth larvae, aphids, mice and so on. Common diseases are root rot, anthrax, blight and so on; the key to the disease lies in prevention, which can be prevented by spraying fungicides such as mancozeb, carbendazim and carbendazim with a small spray can for about a month. Anthurium andraeanum is very sensitive to pesticides and the concentration must be correct when used, and its concentration is usually lower than that used in other flowers. Pay special attention to copper-containing pesticides and dimethoate, methamidophos, dichlorvos, malathion, parathion and so on will be toxic to Anthurium andraeanum.

Key points of Flower planting in Spring
Flower planting Handbook (February)
The weather characteristics of February: this month is the last month of winter and the cold time of the year, second only to January. By the end of February, the weather began to warm and transition to spring, and a considerable number of flowers began to turn from winter dormancy to recovery. The flower events this month mainly include the following aspects: first, continue to do a good job in cold protection and heat preservation of potted flowers in protection facilities; second, do a good job in pruning and changing pots of some woody flowers after flowering; third, do a good job in the preliminary preparations for cutting, grafting and sowing seedlings of some flower species.
1. Sow seeds. The kinds of flowers that can be sown in the greenhouse or greenhouse in February are: calendula, cyclamen, dwarf sunflower, asparagus, crabapple, red and blue flower, cornflower, chrysanthemum, wheat straw chrysanthemum, string red, marigold, peacock chrysanthemum, petunia, Ling Ling grass, Fu Lukao, Prunus chinensis, moth butterfly, goldfish grass, golden lotus, pansy and so on. The seeds that can be sown in the open field at the end of February are Magnolia, Michelia, heather, maple, begonia (Rosaceae) seeds that have been cracked by sand storage treatment, as well as camphor, Liriodendron chinense, privet, rich seeds, fire thorns, palms, Koeluan trees, disease-free seeds, seven-leaf trees, cloves, etc.; seeds such as Chimonanthus praecox, Chimonanthus chinensis, and wisteria should be soaked for 24 to 48 hours, wait for the seeds to absorb enough water before sowing. Late fragrant jade bulbs and red bulbs can also be planted in greenhouses or greenhouses in February.
two。 Cuttings. The woody ornamental plants that can be cut in the open field or covered with plastic film in February are: plum blossom (palace powder, green calyx and other varieties cut off annual branches after flowering), Phyllostachys pubescens, hibiscus (southern region), crape myrtle, Ruixiang (southern region), fragrant, pomegranate, golden bell, welcome spring, Jasminum, June snow, hibiscus, hypericum (plum), Spiraea, ten meritorious efforts, yellow poplar, oil hemp stalk and so on. The branches of lilac and Lingxiao hidden in sand can also be cut at this time. In the first ten days of February, we can continue to cut the branches such as sea immortal flower, Shu Shu, eight immortal flower, Tamarix, Fatong, grape, fig and so on for storage treatment for cutting at the end of March.
The ornamental plants that can be cut indoors in February are: Fusang, triangular flower, African violet (leaf cutting), bamboo crabapple, red-backed cinnamon, a string of red, geranium, jasmine, pearl orchid, bergamot, jade tree, jade leaf, stone lotus, epiphyllum, lotus flower, cold water flower, rooting on the ground, longevity flower, Rieger begonia, dragon spit bead, goose palm wood, Guangdong evergreen, Zhu Jiao and so on.
3. Grafting. One-year-old sturdy seedlings of Pinus elliottii were used as rootstocks indoors, and Japanese five-needle pine, brocade pine and white pine were grafted, and then covered with film to keep warm and moisturizing. One-year-old seedlings such as apricot and hairy peach were used as rootstock to cut and propagate red leaf plum, plum blossom, blue peach, Birthday Bun with Bean Paste Filling, purple leaf peach and so on. In the south of the Yangtze River, when the leaf buds on the branches of Chimonanthus przewalskii grow to the size of the wheat grain, the seedlings of Chimonanthus praecox with a diameter of about 0.8 to 1.2 cm are used as rootstock to propagate excellent varieties such as "Suxin", "Xinkou" and "Tiger's hoof". The survival rate is higher by using bagging inflatable and moisturizing measures. Taking the sturdy branches of rose "Elizabeth" as rootstock, cutting or splitting the scion of rose, and adopting the measures of first grafting and then cutting and then covering with plastic film to keep moisture and cold, the survival rate of grafting can be greatly improved.
4. Press the strip. The ornamental plant species that can be propagated by pressing in February are: plum blossom, wax plum, pedicel begonia, sweet-scented osmanthus, purple magnolia, gardenia, brocade flower, Luohan pine, cypress, snowball, Qionghua, spring, golden bell, hypericum, eight immortal flowers, hemp leaf hydrangea, snow spray, red maple, Michelia mollissima and so on.
5. Ramet. The herbaceous flower species that can be propagated in February are Iris, Shegan, onion orchid, Ophiopogon, auspicious grass, evergreen, purse peony, hairpin, purple calyx, small Taran, pineapple, purple back evergreen, Jianlan, Chunlan, Cymbidium, kidney fern, hanging orchid, ground rooting, canna, bamboo taro, tortoise back bamboo, synthetic fruit taro, crane orchid, gentleman orchid, aloe and so on. The woody flower species that can be propagated in February are: Phyllostachys pubescens, hibiscus, Hypericum, Ten Gonglao, eight Immortals, Begonia, Jiexiang, Yingchun, Golden Bell, Canary, Snow spray, Safflower Spiraea, Jasmine, Pearl Orchid, Tiger thorn, Purple Magnolia, four Seasons Cinnamon, Phoenix tail Bamboo, Phyllostachys pubescens and so on.
1. Gather seeds. The seeds of Phyllostachys pubescens, holly, rich seeds and winter corals can be picked in February, and the seeds can be sown after the seeds are exposed to white. Artificial pollination can be given to the plants of Cymbidium in full bloom in greenhouse in order to obtain seeds with better genetic quality.
In February, we should pay attention to check the seeds of all kinds of flowers and trees stored in sand to see if there is mildew. If mildew occurs, it should be cleaned in time; if the seeds are found to be dry, they can be properly sprayed with water to maintain a certain degree of humidity in the sand and seeds. If it is found that there are a small number of cracks in the seeds, they should be sown in a relatively short time. Once the radicle stretches out too long, it is easy to break the radicle and affect the emergence rate of the seed. Large seeds in sand storage can be sowed on demand, while small seeds can be sowed in strips or rows. After sowing, pay attention to covering grass or plastic film to protect moisture and prevent cold.
two。 Transplanting and planting. In February, the soil in the south is not frozen and the temperature is high. The feasible transplanting species of grass flowers are: Carnation, goldfish grass, hollyhock, silver edge holly, daisy, calendula and so on.
In February, most deciduous shrubs and some evergreen tree species can be planted. Among them, deciduous species such as hibiscus, pomegranate, bauhinia, begonia, ginkgo, maple, maple, wisteria, crape myrtle, wax plum, plum blossom (before germination), magnolia, disease-free, acacia, seven-leaf tree, red-leaf plum, cherry, papaya, Lingxiao, Linden, Liriodendron, green peach, Chinese tallow, Spiraea, three branches, Shu Shu, Robinia pseudoacacia, dragon claw Robinia pseudoacacia, Yu Li, elm leaf plum, hypericum (plum), weeping willow, golden silk willow, wood hibiscus, hibiscus, Yellow peel, persimmon, apricot, etc. Evergreen tree species such as Michelia, camphor, du ying, Fa Qing, run nan, purple nan, etc., can be delayed until the end of February to early March; sweet-scented osmanthus, privet, Shu juniper, dragon cypress, Platycladus orientalis, black pine, etc., should be pruned appropriately.
1. Keep out the cold. The weather is still cold in February. After two months of indoor (greenhouse) maintenance, the nutrient consumption of potted ornamental plants is large, and the resistance of flowers and plants is greatly reduced, so we should continue to do a good job of moisturizing and cold protection. If there are heating facilities in the greenhouse or greenhouse, you should continue to give heating and prevent harmful gases or smoke from escaping into the greenhouse or greenhouse; if you hang grass curtains on or around the top of the greenhouse, you can continue to hang grass curtains; and when you encounter the sudden cooling weather after snow, you can't take it lightly.
Overwintering potted flowers shelved in protective facilities should continue to do a good job of ventilation, especially at the end of February, the ventilation time can be extended during the time of the highest temperature of the day. It is worth noting that indoor potted flowers bask in the sun, it is best to put them on the inside of the south window, do not open the window.
A small number of cold-averse flowers planted in the family, such as Milan, Phalaenopsis, peacock taro, synthetic taro, iron cross begonia, variable leaf wood, pink daiye, etc., in particularly cold weather, you can add plastic bags at night, or leave them in the toilet, turn on heating appliances such as "bath tyrants" and other heating to ensure that they can survive the winter safely.
two。 Water it. In February, due to the low temperature, most of the potted flowers can keep the potted soil moist and be able to survive the winter safely, because at this time, the root growth stops, the metabolism is at a low level, and less water is needed. Once there is stagnant water in the potted soil, it is very easy to cause rotten roots to die. In relatively dry rooms, foliar spraying and spraying should be carried out frequently to increase the air humidity of the local environment. If the indoor air is too dry, the light ones will cause the leaves to lack green and lose color, the buds will stop growing, and the heavy ones will dry up and wrinkle, and the buds will shrink and fall off, such as camellia, tea plum, rhododendron, plum blossom, dai dai, kumquat, winter coral and so on. In addition, it is also required to ensure that the water temperature of watering or spraying is basically consistent with the indoor air temperature and soil temperature in the shed.
[page] for those potted plant species that will blossom before and after the Spring Festival, such as melon and leaf chrysanthemum, primrose, longevity flower, camellia, tea plum, Belgian rhododendron, calendula, etc., and fruit ornamental plants such as firethorn, bamboo, daidai, bergamot, lemon, rich seed, tangerine, winter coral, not only to keep the potted soil moist, but also to spray water on leaves, buds and fruits. Only in this way can the leaves be green, the flower buds expand rapidly and the fruit be colorful. Especially for peony, plum blossom, sticking stem begonia, vertical silk begonia and so on placed in the greenhouse, the branches must be sprayed once or twice a day to accelerate the expansion of their buds, so that they can spit out fragrant flowers as scheduled. Buy back the Cymbidium cultivated in the greenhouse, because the temperature and humidity in the greenhouse is quite different from that in the family, if the leaves are not often sprayed with water, the leaves will often shrink and wither. Potted plants and bonsai placed in the air-conditioning room, especially the Japanese five-needle pine bonsai, must ensure that the potted soil is moist and spray water to the plant once or twice a day, otherwise it is very likely to cause plant death.
Although the vast majority of potted flowers do not need much water in February, inspection should be strengthened, especially if the temperature continues to rise for several consecutive days, and supplementary watering and spraying should be strengthened in time.
In February, green trees and flowering shrubs transplanted in autumn and winter should be watered in time, especially for those evergreen trees and flowering shrubs, foliar spray should be given properly around noon in fine weather to prevent the leaves from drying and falling off, affecting the recovery of growth in spring.
3. Fertilize. In February, we can continue to apply base fertilizer to most green trees and flower shrubs planted on the ground, such as cake manure, barnyard manure, chicken feces and pigeon manure, pond mud, septic tank cleaning, etc., and cover the soil after digging annular grooves from the periphery of the plant root system to meet the needs of plant growth, flowering and fruiting in spring and summer.
In February, potted flowers placed in 10 ℃ to 15 ℃ greenhouses (greenhouses), such as camellia, tea plum, melon and leaf chrysanthemum, primroses, cyclamen, Belgian rhododendron, shrimp flowers, golden bracts, Ruixiang, plum blossoms, European daffodils, hyacinths, tulips, crab claw orchids, lotus flowers, colorful pineapples, iron orchids, fruit vines, magnolia, etc., can continue to apply low concentrations of potassium dihydrogen phosphate. In order to facilitate the growth of the plant and bud flowering. For most of the potted flowers, foliage plants and stump bonsai placed in the greenhouse, including small, miniature bonsai, as they are still dormant, fertilizer should be stopped, otherwise it is easy to cause rotting roots of the plant to die.
4. Trim. In February, the ground or potted plum blossom, wax plum, golden bell, and spring after flowering can be shrunk intensively. The branches that have flowered only retain 2 to 3 buds at the base, and the rest are all cut off to promote them to send more new shoots in the same year, and the branches will be more dense in the coming year. In addition, the long branches, dead branches and irregular branches should be pruned together. The species of tree stump bonsai dominated by scissors, such as hammer elm, Finch, banyan, triangular maple, Fujian tea, oak, white wax, bayberry, Elaeagnus angustifolia, wolfberry, holly, June snow, juniper, juniper, etc., continue to prune the pile head that has not been changed for 1 to 2 years.
5. Change the basin. At the end of February and the beginning of March, it is a favorable time for most potted ornamental plants to change pots, usually when the winter dormancy of plants is coming to an end, the root system resumes growth, but the leaf buds have not yet sprouted. The flower species that can be changed at the end of February are: Fusang, geranium, Milan, Magnolia, jasmine, pearl orchid, dichromatic jasmine, red back cinnamon, kidney fern, tortoise back bamboo, rubber tree, hanging bell begonia, bamboo crab crabapple, four seasons begonia, colored leaf begonia, spring orchid, cymbidium, Jianlan, iron tree, gentleman orchid, 12 volumes, aloe, crab claw orchid, lotus flower, Jingtian, jade tree, jade leaf, longevity flower, Zhu Dinghong, asparagus, hanging orchid, Nanyang fir, Goose palm wood, evergreen, crane orchid, shrimp flower, golden bract, coral flower, Longtuzhu, camellia, tea plum, sticking begonia, eight immortal flowers, southern bamboo, variable leaf wood, fruit taro, bamboo taro, rich seeds, fire thorns, daidai, kumquat, bergamot and so on.
6. Pest control. For powdery mildew on leaves of potted melon and chrysanthemum in greenhouse, gray mold on primrose leaves, 1500 times of methyl thiophanate wettable powder was sprayed at the initial stage of the disease, once every 10 days, 2 to 3 times in succession.
Botrytis cinerea on the leaves and Corolla of cyclamen potted in the greenhouse can be sprayed with 1000 to 1500 times of the wettable powder of 50% prohydantoin (mainly composed of isobarbazide).
The Belgian rhododendron potted in the greenhouse should stop spraying foliar fertilizer such as "multi-effect and good", because at this time the temperature is low and the humidity in the greenhouse is high, the foliar spraying of the plant is difficult to be absorbed, and the reverse side is easy to breed mold on the foliar surface. in serious cases, it will form ugly disease spots.
For aphids, scale insects, ants and coal fouling diseases on potted flowers (such as daidai and kumquat) in the greenhouse, they can be brushed away with a hairbrush when they are small, and those with a large number of insects can be sprayed 2000 times with omethoate EC. After aphids, scale insects and ants are killed, coal fouling disease will also be eliminated.
The insect bodies on potted flower plants in the greenhouse, such as pink Tamarix, white shield scale, oyster shield scale, black brown shield scale, etc., can be brushed with a hard hair brush, or killed with cotton stick alcohol, or 2500 times of 2.5% kungfu EC can be sprayed, or 3% carbofuran and 20% Tiemiak granules can be buried in the flowerpot.
Continue to clean up the dead branches and leaves under the flowers and trees, and burn the diseased leaves on the potted flowers and plants, which can significantly reduce the occurrence of diseases and insect pests in the coming year.
7. Compost. Pour the tea seed cake, rapeseed cake and bean cake into the pool or tank, inject clear water and carry out sealed fermentation, so as to be used to irrigate potted flowers after dilution in the growing season. Or the cake fertilizer is piled up and fermented, spread out and dried after about 2 months, and then packed in a plastic bag after being fully dried. The granular powder of cake fertilizer dried after drying is spread in the flowerpot as topdressing. For Cymbidium, Jian Orchid, Cymbidium, Phalaenopsis, Cartland and other potted flowers, it is more convenient than pouring liquid cake fertilizer, especially raising flowers on the balcony, which is not only convenient and hygienic, but also can reduce the occurrence of foliar diseases. In addition, it can also be used for the preparation of culture soil.
8. Reclaim frozen ponds. In the first ten days of February, the unfinished ploughing garden can be reclaimed, frozen over the winter, and then trenched to make a bed for raising seedlings or transplanting flowers and trees in spring.
The plant species that can be used for flat modeling in February are Cuibai, Luohan pine, Sabina vulgaris, Platycladus orientalis, Platycladus orientalis, Sabina vulgaris, ginkgo, June snow, ground cypress, five-needle pine, yellow mountain pine, black pine, thousand-headed red pine, bayberry, golden finch, small money plum, wax petal flower, sticking begonia, crape myrtle, banyan tree, elm, triangle maple and so on.
The plants modeled 1 to 2 years ago were re-banded and adjusted, and it was found that the plants had concave constrictions. The metal or non-metallic wires should be released and replaced with new binding materials for flat binding and fixation.
For shallow pot tree stump bonsai, landscape bonsai, small miniature bonsai, stone bonsai, etc., continue to do a good job of heat preservation and cold protection, so that they are always in an environment of no less than 0 ℃, so as to prevent plants from freezing to death or artificial cemented rocks from being frozen and disintegrated, resulting in unnecessary losses.
Flower planting Handbook (March)
(1) types of flowers suitable for planting in the courtyard
1. Species of flowers planted in the ground
If the front of your courtyard is open and open, the lighting and ventilation conditions are good, or the distance between your courtyard and the front row of buildings is more than 30 meters, and the soil has been improved to a certain extent, you can plant some flower species that like light and have higher requirements for the growth environment.

(3) Management of courtyard flowers
1. Management of flowers and trees in ground-planted courtyard
(1) transplanting. March is the best time for transplanting and planting of ground-planted flowers and trees, in which the transplanting of plum blossom, magnolia, magnolia, Magnolia, Liriodendron and red maple should be arranged as far as possible before sprouting and spreading leaves; evergreen flowers and trees should be pruned in order to reduce transpiration and improve the survival rate. The transplanting of Chimonanthus, crape myrtle, bauhinia, hibiscus, seven-leaf tree, green peach, red leaf plum, cherry blossom, etc., even after sprouting, should be pruned properly. Whether evergreen trees or deciduous trees, they should take enough soil balls when transplanting, and the diameter of soil balls should be more than 6 times of the diameter of the trunk.
(2) fertilization. For the ground-planted flowers and trees that have not been given buried fertilizer in winter, when they have not yet germinated, they can dig circular ditches outside their roots with a depth of about 15 to 20 cm, and apply thoroughly melted cake manure, barnyard manure and chicken droppings and pigeon manure. It can also be a multi-component compound fertilizer to lay a good material foundation for its growth throughout the year.
[page] (3) pruning. For the plants that have not yet been pruned, especially the plum blossom, wax plum, Golden Bell, Yingchun, etc., in addition to the dead branches, disease and insect branches, and only 2-3 buds can be truncated at the base of the branches, and only 2-3 buds can be retained after intensity shearing, so as to sprout more new branches in spring and more pregnant flower buds in summer and autumn, so as to facilitate the flowering in the coming year. For camellia, tea plum, etc., you can prune after flowering to destroy the branches of the plant shape, and at the same time trim off some thin branches and cross branches of the inner chamber. Pomegranate, hibiscus and sweet-scented osmanthus which formed flower buds and bloomed on the new branches in the same year can be pruned in March to adjust the plant shape and improve the ventilation and light transmission of the plant.
(4) Prevention and control of diseases and pests. The branches and leaves that have been infected with diseases and insect pests on the plant should be cut off and destroyed in time, so as to reduce the occurrence of diseases and insect pests in the same year; for some flowers and trees that are easily infected with diseases and insect pests, such as rose, wood claw, pedicel begonia, grape, vertical silk begonia, etc., timely spraying Bordeaux solution after leaf expansion can prevent the occurrence of powdery mildew and rust.
two。 Management of grass and flowers in courtyard planted in the ground
The species of grass flowers that can be transplanted and planted in March are: carnation, goldfish grass, calendula, daisy, hollyhock, mallow, Ophiopogon japonicus, green onion orchid, leek orchid, iris, auspicious grass, book belt grass, Ophiopogon japonicus, safflower sorrel and so on. For grass flowers transplanted before February, or those transplanted a year ago, if the plant has resumed growth, such as kale, pansy, etc., weeding and loosening the soil can be done first, and then low concentration liquid fertilizer can be applied, such as steamless cake fertilizer water, 0.5% urea solution, or other quick-acting compound fertilizer solution.
3. Management of potted flowers and trees in courtyard
(1) change the basin. Potted plants such as Chimonanthus praecox, Plum blossom, Begonia, Tripterygium, Pyracantha, Pinus pentaphylla, Phyllostachys pubescens, Ulmus pumila, Maple, Oak, and White Wax can be changed before germination and leaf extraction, so as to replace the fresh culture soil which is loose and rich in organic matter, so as to lay a good foundation for the growth of spring and summer. For Magnolia, Milan, Zhulan, rose, jasmine, Fusang, crane orchid, iron tree, poinsettia, tea plum, camellia, Belgian rhododendron, rich seed, dai dai, bergamot, lemon, tortoise back bamboo, spring feather, gentleman orchid, cherry, fruit taro, bamboo taro, etc., should be changed before leaving the room.
(2) exercise. In the area north of the Yangtze River basin, most of the potted flowers are still under indoor maintenance in March, and equal attention must be paid to cold protection and ventilation. Due to the unstable weather this month, it is necessary to continue to do a good job of heat preservation and cold protection in the first and middle of March due to the unstable weather this month. In late March, the doors and windows of the bedroom can be opened during the day for ventilation and closed at night. So that Magnolia, Milan, Zhulan, jasmine, Fusang, poinsettia, tortoise bamboo, cherub, rubber tree, southern fir, etc., can gradually accept exercise and adapt to the outdoor environment. Avoid affecting the growth and normal flowering of the year due to early germination. Potted flowers in the north of the Yellow River need to continue to do a good job of heat preservation and cold protection this month, and must not be taken lightly.
(3) pruning. Carry out the necessary pruning of Fusang, Admiralty, dragon spitting beads, jasmine, pearl orchid, magnolia, iron tree, rubber tree, fish-tail sunflower, loose-tailed sunflower, variable leaf wood, asparagus, begonia, combined with changing pots, including cutting off branches of diseases and insect pests, dead branches, disordered branches, thin branches and some yellowed leaves. For Acer truncatum, Luohan pine, cypress, Huangshan pine, black pine, elm, white wax, oak and red num, which are mainly appreciated for stumps, flat binding and pruning can also be carried out before germination in March to further improve their shape. For plum blossom, wax plum, rose, green peach, Yingchun, Admiralty, etc., intensity shearing can be carried out before germination after anthesis.
(4) types of flowers suitable for balcony planting
It is impossible for every urban household to have a small courtyard, to live on the first floor, to have a better environment for growing flowers, and to grow more resistant ornamental plants on the balcony to decorate the interior, improve the living environment, and create an atmosphere of returning to nature.
The ornamental plants suitable for planting on the balcony are drought-tolerant plant species, which are proliferated on the surface of the body or stratum corneum, or are waxy, or the plants are fleshy and contain more juice, or the leaves are small, transformed into needling, with very little transpiration, or native to arid desert areas and can withstand wind and heat, so they are very resistant to drought. Such as iron tree, cactus (yellow hair cactus, mountain shadow boxing, green lock dragon, golden oyster, big wheel column, Prajna, rat tail, coral tree), purslane, jade tree, stone flower, stone lotus, epiphyllum, arrow lotus, leaf cactus, longevity flower and so on. There are Chimonanthus, Yingchun, Lycoris, silver taro, Guangdong evergreen, hanging orchid and so on, these flowers are generally not watered in 2 to 3 weeks in spring, will not be killed, balcony planting is more appropriate. There is also a kind of flowers that are more resistant to sun exposure and dry and hot wind, which can accept full light and can withstand abnormal high temperature for a short time, and are also suitable for potted plants on balconies (especially high-floor balconies). Such as pomegranate, rose, banyan, stick orchid, lobular privet, tequila, Zhu Dinghong, sparrow, oak, hammer elm, triangular maple, bayberry, black pine, juniper, juniper, cypress, wolfberry, holly, bauhinia, weeping spear, Birthday Bun with Bean Paste Filling, sunflower and so on. In addition, jasmine, pearl orchid, five-needle pine, Milan, one-leaf orchid, bergamot, daidai, lemon, rubber tree, tortoise back bamboo, spring feather, camellia, goose palm wood, Nanyang fir, etc., can also be used as lower balcony potted plants, but water and shade management should be strengthened.
(1) Propagation of potted flowers on balcony.
Grass flowers suitable for balcony potted plants, such as a string of red, colorful peppers, winter coral, marigold, impatiens, petunia, etc., can be sown and raised in a shallow pot at this time.
If a small amount of asparagus and magnolia seeds are collected and washed, they can be sown indoors first, and then moved to the outdoor balcony for cultivation when the outdoor temperature reaches about 15 ℃.
Succulent plants such as arrow lotus, epiphyllum, Yushu, gemstone, stone lotus, purslane, coral tree, green lock dragon, etc., can be cut indoors with plain sand or clean sandy loam soil, and then moved to the balcony after the spring is warm.
Large flowerpots are filled with loose sandy soil, or vermiculite and perlite are used as cutting substrates. Gardenia, golden bell, Fusang, triangular plum, Luohansong, rose pomegranate, tapping begonia, southern bamboo, Ruixiang, Fugui seeds, etc., but the mouth of the pot should be covered with plastic film to moisturize.
On the balcony, grafting five-needle pine, golden pine, plum blossom, Birthday Bun with Bean Paste Filling, red maple, wax plum and so on, to carry out bagging moisturizing, otherwise it is not easy to survive.
(2) Management of potted flowers on balcony
1. Keep out the cold. Most of the ornamental plant species suitable for balcony potted plants are still indoors in March. While taking measures such as heat preservation and cold protection and ventilation to see the light, the plants that need to be changed should be changed in time. Flowers and trees with strong resistance placed on the balcony should keep the potted soil from freezing. If the potted soil freezes and pulls out, it will not only affect the normal growth of the plant in that year, but also cause plant death in serious cases. It can be protected by setting up a shed on the spot or moving into the room or shed to protect against cold.
two。 Trim. The stumps such as wax plum, wolfbone, holly, black pine, five-needle pine, Luohan pine, triangular maple, hammer elm, Finch plum, bayberry and lobular privet can be trimmed and reshaped, and the trunk and branches that need to be modeled can be fixed in March, and the plants that have not changed pots for 2 to 3 years can be changed soil; put bonsai on the balcony to keep the basin soil moist, watering every 3 to 5 days, and spray water appropriately. Plum blossom, spring welcome, Golden Bell, Chimonanthus, Birthday Bun with Bean Paste Filling, Camellia, etc., can carry out necessary shaping and pruning after flowering to promote a good plant shape, carry out a comprehensive cleaning of the plant, cut off the branches and leaves infected with diseases and insect pests, and destroy them; the dry cross section on the stump can be treated with stone sulfur mixture.
3. Preparatory facilities. If the conditions permit, you can also build a small pool on the balcony, support the hard board (prefabricated cement steel bar), make use of the humidity produced by the pool evaporation, and put some flowers on it that prefer the air moisture in summer, such as orchids, tortoise back leaves, hulks, cherubs, rich seeds, southern bamboos and so on. Among them, water storage is ideal for watering flowers.
In March, you can also take advantage of the potted flowers before leaving the room, first set up a ladder shelf to put the potted flowers on the balcony, and choose the support point of the summer sunshade net. once the potted flowers come out of the room and encounter excessive sunlight, shading measures can be quickly put in place.
In March, we should also prepare the cultivation soil to change the basin and prepare all kinds of fertilizers and pesticides to meet the needs of planting flowers on the balcony in a year.
Flower planting Handbook (April)
The weather characteristics of April: with the weakening of the cold air going south in the north, the warm and humid air flow in the south becomes stronger and stronger, and the temperature rises obviously. After the Qingming Festival, although there is an occasional influence of cold air going south, it can no longer pose a threat to most of the potted flowers in the south of the Huaihe River, only to the north of the Huaihe River and the Yellow River. After Grain Rain, the night frost has ended in the south of Jianghuai, the minimum temperature is not less than 5 ℃, and Rain Water has obviously increased. Most of the potted flowers can be moved to outdoor maintenance, while the Huaibei area will not be able to let the potted flowers out of the house until the end of the late frost in May. From south to north in April, the flower show has the following contents:
I. Flower reproduction
1. Sowing seeds
The flowers suitable for sowing in April are drunken butterfly, purple jasmine, cockscomb, wild goose, sunflower, Xiaoli, thousand-day red, a string of red, impatiens, morning glory, rain-leaf pineapple, round-leaf pineapple, safflower tobacco, petunia, emerald chrysanthemum, golden chrysanthemum, snake chrysanthemum, marigold, red yellow chrysanthemum, hundred-day red, asparagus, spring report, dry golden lotus, ground skin, maple, poinsettia, basil, Tianmen winter, Persian chrysanthemum, sand ginseng, sand ginseng, Mimosa and so on. The species of Magnoliaceae that can be sown in April and stored in sand are: Magnolia Magnoliae, Magnolia mandshurica, Magnolia magnolia, Magnolia mandshurica, Magnolia mandsh North American Liriodendron chinense, etc. Can be broadcast in April
Other greening flowers and trees are: Japanese fir, golden pine, Nanyang fir, golden pine, crape myrtle, bauhinia, acacia, yew, Haitong, Chinese tallow, Huangshan moss, free son, maple, maple, flower palm, wax plum, summer wax plum, rhododendron plum, Chinese wolfberry, southern bamboos, rich seeds, palms and so on.
The ornamental plants that can be picked and sown in April are: Fulang flower, asparagus, primrose, winter coral, star anise gold plate, milk eggplant and so on. Among them, star anise gold plate can pick the blackened, whitened and soft fruit at the end of April, scrub out the seeds, sow them on a fertile seedbed, or first hide the seeds to the crack to show white, then sow and cover the grass to moisturize. In general, after two weeks, about 70% of the seeds emerge, the grass should be removed in time, and a shed should be built for shade. On the other hand, the cultivated milk eggplant can peel off the picked golden fruit, wash the seeds, soak the seeds in warm water for 24 hours, sow them in the fertile sandy soil, and sprout the seeds 10 days later. When the seedlings grow 6 to 8 true leaves and the plant height reaches 15 cm, they can be transplanted, which can be cultivated either in pots or as special cut flower materials.
two。 Grafting
The flowers and trees that can be grafted in April are: wax plum, dragon claw locust, green peach, Shouxing peach, safflower black locust, cactus and crab claw orchid and so on.
3. Ramet
The greenhouse foliage plants that can be propagated in April are: White crane taro, tiger tail orchid, one-leaf orchid, fern, brown bamboo, hanging orchid, tequila, silver emperor evergreen, evergreen, Guangdong evergreen, bamboo taro, aloe, pepper grass, tortoise back bamboo, In the trench of the school, the ⑽ rate of permanent muscle in the trench of Chunyu and other crabs: ⒑, , ⒎, Falcon, ⒆, ⒖, ⒑, pyramidal, ⒔, ⒈, ⑶, caries, ⑶, ⑺, , ⒚, ⒚, , ⑼, scale, salary, ⑼ scale, en22# trickle umbrella, en24# Linden Do you want to drop out of ⑤, your ⒋, your cynicism, your ⑼ , your shrugged nose?
4. Cuttage
For most species of flowers and trees that are easy to take root, as long as their leaf buds have not yet germinated, they can be propagated by cuttings in April. the main species are: yellow poplar, ten meritorious categories, southern bamboo, cypress, Luohansong, pomegranate, crape myrtle, bauhinia, firethorn, Spiraea, Liriodendron, snowflake, fragrant, sticking begonia and so on.
Second, changing pots and transplanting
1. For potted flowers that do not have time to change pots in March, pots can be changed in April as long as the tips are not too long, or as long as the persistent soil is not broken and the roots are shrunk too much during the change. But it should be pointed out: deciduous flowers and trees, if the shoot is too long, especially the plum blossom, do not change the pot after spreading the leaves.
two。 April is the best time for transplanting flowers and trees in the open field, whether deciduous flowers or evergreen flowers and trees, as long as their leaf buds have not yet unfolded or their shoots are not long, they can be transplanted with soil balls in April; for evergreen flowers and trees, such as camphor, Magnolia, Michelia and Magnolia, some branches and leaves must be cut off in order to reduce the transpiration of the crown to water. For deciduous flowers and trees, it is best to transplant when they are unfoliated, such as Magnolia, seven-leaf tree, Linden, begonia, wax plum, red leaf plum, ornamental peach, plum, apricot, etc.; usually the diameter of the soil ball transplanted should not be less than 6 times the diameter of the trunk of the transplanted flowers and trees, so that the transplanted flowers and trees can have no worries under the condition of not destroying the soil balls.
Third, bonsai modeling
April is one of the best times for bonsai styling. The ornamental plants most suitable for beginners to practice modeling are those with strong adaptability and branches that can withstand repeated twisting and binding of branches by beginners, which do not seriously affect their normal growth, such as Luohansong, Cuibai, June snow, bayberry, cypress, weeping spear, crape myrtle, velvet cypress, flower cypress, banyan tree, melon seed yellow poplar, hammer elm, welcome spring, knot incense, ginkgo, black pine, juniper, and so on. Other kinds suitable for April modeling include wild Hawthorn, five-needle pine, Huangshan pine, green peach, pyracantha, Chinan, white wax, triangular maple, oak, Galo wood, golden marbles, vertical silk begonia, Fujian tea, papaya, Elaeagnus angustifolia, wolfbone holly, golden pine, tiger thorn and so on.
With the beginning of the vigorous growth of bonsai plants, it is necessary to use wire or non-metallic wire in time to carry out flat traction and correction, so that it can always maintain a good ornamental state. For the maintenance of five-needle pine bonsai, special attention should be paid to the following three aspects this month: first, pick buds in time. When winter buds sprout and granular needle primordia appear on them, the length of buds can be removed from 1 canister 2 to 2 canopy 3, which makes the new shoots shorter and denser. The second is to erase the male and female jerseys, when the needle buds and male and female cones can be identified from the new shoots, all the female cones born at the top of the new shoots and the male cones at the base of the new shoots should be erased in time, so as to reduce the consumption of nutrients during reproductive growth; the third is to control watering, starting from the new shoot, we should strictly control watering, do not dry, do not irrigate, spray instead of watering, to ensure that the new needles short clusters, so that branches keep smooth and good.
IV. Fertilization management
1. Fertilizer application
Potted camellia, tea plum, wax plum, rhododendron, spring welcome, Admiralty, Ruixiang, kumquat, daidai, winter coral, crab claw orchid, Cymbidium, etc., because their flowering or fruit consumes a lot of nutrients, it is necessary to apply nitrogen-based fertilizers, such as thin cakes, to promote their growth when they resume growth after spring warming. Potted flowers such as rose, bauhinia, pomegranate, Jianlan, Fusang, and Magnolia should also be fertilized, which can be potassium dihydrogen phosphate, and the concentration can be controlled at about 0.2%. Magnolia, Magnolia, Michelia, plum blossom, wax plum, begonia and so on should also be fertilized in time to meet the needs of their vegetative growth.
two。 Shaping and maintenance
The rich tree can braid its hair in April. Dig up the seedlings of the rich trees sown or purchased, spread them out in a shady place for 1 to 2 days, let them lose part of their moisture, and then braid them with odd trunks of 3, 5 and 7, and then press them with heavy objects after braiding. After fixing its shape, choose a suitable pot planting; the vitality of the rich tree is so strong that even if it is not processed into braided or planted in time, it will not affect its survival and normal growth in the future.
3. Adjust plant shape to prevent diseases
For potted flowers moved outdoors, withered branches, yellow leaves and abortive stems should be eliminated in time, plant shape adjustment should be carried out, and water and fertilizer management should be strengthened. For flower species prone to diseases, stone-sulfur mixture or Bordeaux liquid should be sprayed in time to prevent possible diseases.
4. Pot management of viewing fruit
For potted ornamental fruit flowers and trees that bloom in April, such as papaya, ginkgo biloba, pyracantha, peach leaf coral, crabapple, etc., especially dioecious or cross-pollinated species, attention should be paid to creating favorable conditions for pollination and fertilization during the flowering period. so that it can be fertilized normally, do not miss the opportunity.
5. Management of cutting seedbed
For ornamental plants that have just been cut, special attention should be paid to the management of water spray before the healing tissue is formed. except for those with intermittent spraying devices, water (fog) must be sprayed 2 to 3 times a day to keep the cutting substrate moist all the time. to create an optimal environment for its healing and rooting.
Flower planting manual summer
Flower planting Handbook (May)
The climatic characteristics of May: the temperature continues to rise, and the rainfall in our country increases gradually from south to north. After each fall of Rain Water, the temperature increases obviously. The weather with more spring rain and continuous rain turns to muggy after the spring rain of Lesser Fullness of Grain ends, which marks the beginning of summer soon. Therefore, May at the turn of spring and summer is a key period for growing flowers, which plays an important role in laying the foundation for the growth of potted flowers in summer and autumn. The cultivation of flowers from south to north in May mainly includes the following contents:
I. Flower reproduction
1. Sowing seeds
The main types of flowers and trees that can be picked and sown in May are: spring of the four seasons, star anise gold plate, broad-leaf ten meritorious works, loquat and so on. When sowing and raising seedlings in May, we should pay attention to the following three points: first, we should keep the seeding bed moist, so that we can neither accumulate water nor lose water too much; second, we should cover the seeding bed with grass to keep it moist, so as to prevent the seedling bed from becoming dry and wet suddenly, causing the seeds to "sprout"; third, after emergence, we should remove the covered grass several times and set up a shed in time to shade the seedlings so as not to burn the seedlings.
Sweet-scented osmanthus can pick ripe blue-black fruit at the end of May, rub it with sand to remove the pulp, rinse and store it in wet, clean sand until February next year. When the seed cracks and the radicle tip is exposed, the seeds can be sown in the ground. During storage, attention should be paid to prevent rodents from stealing food and keep the sand moist.
Loquat sowing, covering soil should not be too deep, generally no more than 2 to 3 cm is appropriate.
two。 Cuttage
The flower species suitable for cutting propagation in May are: red (pink, purple, white), thousand-day red (white), marigold, peacock, dragon mouth, he's impatiens, colourful leaf grass, begonia, sulfur chrysanthemum, rose, rhododendron, Dahlia, hanging bell begonia, coral flower, poinsettia, geranium, geranium, leaf flower, mulberry, paulownia, golden lotus, hairy jasmine, pearl orchid, red mulberry, Shu Shu, eight immortal flowers, Ditang, jasmine, Pomegranate, hibiscus, drunken fish grass, Lingxiao, gardenia, epiphyllum, unicorn leaf, Arrow lotus, jade tree, gemstone flower, tiannu flower, magnolia, sticking stem begonia, dry umbrella grass, five-colored plum, red-backed cinnamon, shrimp flower, golden bract, longtuzhu, Guangdong evergreen, Zhu banana, green apple, goose palm wood, oleander, fire thorn, ten great efforts and Buddha belly bamboo with gas roots, etc.
3. Grafting
In May, we used potted 1-2-year-old purple magnolia or cuttage seedlings to propagate white orchids with smiling flowers, red maple, feather maple, coir maple, etc. cutting seedlings of 2-to 3-year-old rhododendron were used to split propagation of rhododendron; excellent varieties of Chinese rose were propagated by bud grafting with wild rose as rootstock; superior varieties of chrysanthemum were grafted with Artemisia annua as rootstock The two-year-old seedlings of Chimonanthus praecox are used as rootstock, and the excellent variety of Chimonanthus chinensis can also be grafted with potted rootstocks. In addition, cactus and trigonous arrow can be used as rootstock to propagate crab claw orchid by grafting.
4. Pressing strip
The flowers and trees that can be propagated under high pressure in May are: Magnolia, rubber tree, Milan, rhododendron, camellia, variegated wood, Michelia, red maple, etc.; flowers and trees that can be propagated under low pressure are: plum blossom, wax plum, rose, gardenia, Luohan pine, sweet-scented osmanthus, Lingxiao and so on.
2. Potting and transplanting
1. Upper basin
Most of the potted flowers used for street decoration during the National Day must be planted in May. After three to four months of careful maintenance, they can blossom on time at the end of September and the beginning of October, so as to create a festive, warm and colorful atmosphere. The main species are: a string of red (pink, white, purple), thousand-day red (white), cockscomb, hundred-day red, sulfur chrysanthemum, chrysanthemum, ground skin, marigold, Longkou flower, Tianmeng, he's impatiens, colored leaf grass, begonia and so on.
two。 Transplant
At the end of April and the beginning of May, when Magnolia Magnolia was transplanted from the end of April to the beginning of May, the survival rate was the highest. Some flowers and trees that germinate late and are easy to survive can also be planted with soil balls in early May, such as crape myrtle, hibiscus, bauhinia, pomegranate, acacia and so on.
III. Flower management
1. Watering
To this end, tap water can be first injected into a pool or small tank, and then an appropriate amount of acidified substance is added to improve the acidity of water quality, such as ferrous sulfate, whose concentration can be controlled between 0.1% and 0.2%. Fruit categories are: daidai, firethorn, kumquat, bergamot, lemon, southern bamboo, winter coral, rich seeds and so on.
two。 Pruning, picking buds
(1) pruning the shearing of white orchids shortly after leaving the room, special attention should be paid to the loose pith of its branches, and the cross section is easy to lose water and dry up and extend downwards. For this reason, consideration should be given to cutting 8 to 10 centimeters above the bud eye, not too close to the bud eye. Pruning after potted rose flowers should be moderately reduced by 10 to 20 centimeters, and the bud eyes located in the middle of the branches can give birth to flower buds.
(2) picking buds for potted Chimonanthus plants, we should also pay attention to the position of picking buds, generally 3 to 5 centimeters above the selected leaf buds, otherwise they will wither and atrophy because of the wound, which will affect the selected leaf buds downwards. For the rose on the basin in the same year, the terminal buds should be removed in time to promote the formation of a good plant shape.
3. Shade
After entering May, potted plants that like semi-shade or shade should be moved under the shade or in the shade, such as: tortoise back bamboo, brown bamboo, taro, spring feather, hulk, red (green) gemstone, green emperor, pink daiye, sunflower, taro, orchid, rhododendron, crane orchid, camellia, tea plum, etc.; flowers and trees that like light must be given full light, such as wax plum, iron tree, rose, pyracantha, jasmine, magnolia, etc. Bonsai plants, such as hammer elm, sparrow plum, triangular maple, bayberry, oak, June snow, black pine, cotton pine, etc., require sufficient light, while Luohan pine, tiger thorn, Chinan, Cuibai, five-needle pine and so on can be shaded appropriately.
4. Fertilizer application
To Camellia, rhododendron, tea plum, plum blossom, Milan, jasmine, white orchid, gardenia, wintersweet, rose, Ruixiang, gentleman orchid, orchid, begonia, etc.; to pick off the residual flower stem after the flower fade, and to apply nitrogen-based and phosphorus-supplemented compound fertilizer once every semimonthly to lay a good foundation for its pregnant flower buds while restoring its vegetative growth. For foliage-based species, such as rubber trees, tortoise-backed bamboos, hulks, red (green) gems, green emperors, spring feathers, orchids, ferns, etc., the fertilizer and water of thin pancakes are applied once every half month. For foliage plants with colored spots and patterns, such as Phnom Penh tiger tail orchid, colorful pineapple, golden heart Brazilian wood, variable leaf wood, colored leaf taro, white butterfly taro, pink leaves, etc., 0.2% potassium dihydrogen phosphate solution can be applied outside the root to make the leaf color look more beautiful and bright.
5. Pest control
For roses, etc., we should pay attention to the control of powdery mildew and brown spot, timely spraying pesticides to kill leaf-eating pests, and to common leaf-eating pests such as daidai, kumquat, golden bean, bergamot, lemon and rue. Citrus butterfly larvae should be killed by spraying as soon as possible.
Fourth, bonsai modeling
The ornamental bonsai plants that can still be modeled in May are: plum blossom, lobular gardenia, mountain gardenia, Luohansong, June snow, emerald cypress, bayberry, Galo wood, ginkgo and so on. It is worth noting that: modeling must be careful, try not to hurt the branches and bones, otherwise it will affect the normal growth of plants.
Flower planting Handbook (June)
The weather characteristics of June: from time to June, the temperature rose further. The Yangtze-Huaihe River Basin has entered the Meiyu season, entering the plum on June 12 and coming out on July 7 this year, when the evenly matched cold and warm air met in the region, causing frequent frontal or cyclone activities. June is the season with the largest number of Rain Water of the year, with long periods of continuous rainfall. Special care should be taken for some dormant or semi-dormant flowers and most bonsai in summer, so as not to cause rotten roots due to Rain Water, or plant growth due to lack of light, disturbing the shape or affecting the normal flowering and fruiting of ornamental plants. The main contents of raising flowers from south to north in June are as follows:
I. Flower reproduction
1. Sowing seeds
The flowers and trees that can be sown in June are: primrose, lotus seed, cycad, loquat, wax plum and so on. The thickness of the covered soil is generally 2 cm to 3 cm, covered with straw to moisturize. After the cotyledons of most seeds are unearthed, remove the grass for 2 to 3 times and build a shed for shade in time.
two。 Cuttage
In summer, the temperature and humidity are high, and the cambium in the branches of flowers and trees is active, which is the best time for cutting to propagate flowers and trees. There are two kinds of flowers and trees suitable for softwood cutting in summer. One is the species of hardwood cuttings that are not easy or slow to take root, such as sweet-scented osmanthus, camellia, Michelia mollissima, medlar, holly, clove, magnolia, tapestry, snowball, Qionghua, coral tree, paulownia, Belgian rhododendron, Buddha belly bamboo (root with air), rubber tree, metasequoia, pond fir, Sequoia lanceolata, etc. The other is the species that are easier to take root. Such as yellow poplar, rose, fiery thorn, golden bell, welcome spring, Jasmine, June snow, pomegranate, hibiscus, golden Finch, jasmine, pearl orchid, dragon leaf bead, five-colored plum, Diitang, leaf flower, bergamot, lemon, Luohansong, southern bamboos, Lingxiao, red back cinnamon, honeysuckle, Fusang, plantain, hypericum, honeysuckle, golden willow, dragon claw willow, banyan, Brazilian iron, cinnabar root, incense, changing leaf wood, Shu Shu, mountain plum, crape myrtle, banyan tree Sea immortal, brocade flower, hemp leaf hydrangea, peach coral, goose palm firewood, ten meritorious categories, star anise gold plate, snowspray, eight immortal flowers, poinsettia and so on. It also includes a large number of other grass flowers, such as five-clawed golden dragon, brocade, golden lotus, piano Finch, Qianqiu tea, perfume grass, dry umbrella grass, geranium, colored leaf grass, begonia, tricolor pansy, thousand-day red, hundred-day red, malachite, marigold, sulfur chrysanthemum and so on.
Take the fully closed moisturizing cuttings of camellia and sweet-scented osmanthus as an example: the cutting time is from early June to mid-July, when the twigs of sweet-scented osmanthus and sweet-scented osmanthus are semi-lignified, and the substrate can be yellow soil, sandy soil or vermiculite. Cuttings are new shoots of the year, 10 cm to 15 cm long, leaving only 2 to 3 leaves at the end. Dip the lower incision with 500mg / kg 1#ABT rooting powder or naphthalene acetic acid solution for 10 seconds, dry slightly and insert it into the seedbed. The depth of the cuttings is 1x2 to 2cm, and the row spacing is 2cm × 8cm. After pouring water, set up a bamboo bow on the seedbed, then cover it with plastic film, press it tightly with mud around, shade the light in a double-layer shade, keep the bed moist, control the temperature in the film at about 30 ℃, and keep the humidity above 90%. Generally, a large number of cuttings can take root after one month.
3. Grafting
Grafted, potted seedlings of Chimonanthus praecox were used as rootstocks, excellent varieties of Chimonanthus were grafted, and potted Magnolia and Magnolia seedlings were used as rootstocks to graft Magnolia and Michelia. Budding, using wild rose seedlings as rootstocks, grafting to breed excellent rose varieties; using apricot, peach, plum and other annual seedlings as rootstocks, budding breeding Birthday Bun with Bean Paste Filling, green peach, purple leaf plum, red leaf peach, Yu plum, plum blossom, etc.; using 1-2-year-old maple seedlings as rootstocks, grafting breeding red maple, feather maple, red maple and so on. Branch grafting, Camellia oleifera, Camellia oleifera or Camellia oleifera seedlings as rootstocks, Camellia oleifera and Camellia oleifera as rootstocks, "Purple Butterfly" and "Jade Butterfly" in rhododendron as rootstock, split or abdominal grafting of Belgian rhododendron or western rhododendron.

5. Ramet
The flower species that can be propagated in June are: kidney fern, calla lily (after anthesis), Phyllostachys pubescens, dry umbrella grass, purple evergreen, pineapple, twelve volumes, one-leaf orchid, calamus, Ophiopogon, and so on.
II. Seed harvesting and transplanting
1. Harvest seeds
The grass flower seeds that can be harvested in June are: carnation, cornflower, goldfish grass, dwarf snow wheel, high snow wheel, hollyhock, mallow, primrose, bungee, Zhu Dinghong (sown with picking) and so on.
Flower and tree seeds that can be harvested in June: after harvest, if the nursery conditions are not allowed, the detached seeds can also be dried and sown until next spring, which will not affect their germination rate; peaches and apricots should be sowed as they are picked, or the seeds should be stored in the crack to germinate and then sow. The sweet-scented osmanthus seeds harvested in June were removed from the fleshy pericarp and washed, stored in wet sand to promote the post-ripening of the embryo, and then sowed in the nursery when they germinated.
two。 Transplanting, planting and potting
In June, a considerable number of grass flowers need to be transplanted and planted or put on the pot. they are: evening primrose, drunken butterfly, impatiens, guinea impatiens, primroses, ornamental peppers, winter corals, red tobacco, petunia, marigold, peacock grass, hundred-day grass, thousand-day red, a string of red, dragon mouth flower, ground skin, sulfur chrysanthemum, cockscomb, red-green grass and so on.
In summer, some large flowers and trees are no longer transplanted, so as not to affect their survival rate and growth after transplanting. However, for some small flowering shrubs, such as star anise gold plate, broad leaf ten meritorious service, ten meritorious service, hypericum, gardenia, Phnom Penh privet, red leaf Berberis, boxwood, under special circumstances, transplanting with the ball is fine, just as the old saying goes: "never move, do not call tree knowledge", but it is necessary to strengthen the management of water spraying and shading after transplanting.
III. Flower management
1. Watering
Watering potted flowers in June should pay attention to the following aspects: first, watering time, 10:00 or 5pm is better, usually watering once a day; second, watering temperature, watering water should be kept basically consistent with basin soil temperature, if the difference between water temperature and soil temperature is too large, it will cause potted flower roots and leaves to be stimulated and then affect their growth. Third, the combination of watering and spraying, when it has not rained for several days, in addition to watering the basin, it is also necessary to spray water around the leaves and potted flowers in order to improve the humidity of the local space. If there is a continuous cloudy day, it depends on the dry and wet condition of the basin soil to decide whether to give watering and spraying.
A species of flower that enters semi-dormancy or dormancy in summer. Semi-dormant people such as safflower sorrel, geranium, golden bell, orchid, calla, begonia, etc., when the temperature is more than 30 ℃, because their growth activity is very weak and metabolic level is low, it is necessary to reduce watering and keep the basin soil moist. The types of deep dormancy, such as cyclamen, Lycoris (class), buttercup, Dutch peony, etc., show that the aboveground stems and leaves wither, the underground nutrient fibrous roots wither, and the underground stems or tubers dormant in the soil for the summer, which must be stopped watering and moved to a cool place to keep the basin soil from being too dry.
[page] if there is continuous rain, check the potted flowers thoroughly after the rain stops and find that there is stagnant water in the pot. pour them away as soon as possible, loosen the soil after the pots are dry, so as not to cause rotten roots, or knock down the potted flowers before the heavy rain, and then straighten the potted flowers after the rain stops.
two。 Fertilizer application
For exuberant species Such as tortoise back bamboo, hanging orchid, synthetic taro, bamboo, kidney fern, spring feather, iron tree, one-leaf orchid, green giant, red (green) gemstone, green emperor, green queen, rubber tree, Anthurium, red back cinnamon, palm bamboo, southern sequoia, Brazilian iron, Luohan pine, wealth tree, wax plum, rose, Magnolia, Milan, jasmine, pearl orchid, plum, camellia, tea plum, Ruixiang, rhododendron, cinnamon, five-colored plum, Longtuzhu, shrimp, dai, dai Lemon, kumquat, pomegranate, crape myrtle, pyracantha, etc. The thin cake fertilizer and water that can be retted thoroughly every half a month, and the species that are blooming, but also apply an appropriate amount of phosphorus and potassium fertilizer to meet the needs of its growth, flowering and fruit hanging.
For those flower species that are dormant or semi-dormant, fertilization must be stopped; especially for those succulent flower species, such as jade leaves, crab claw orchid, crystal cactus, cactus pen, squirrel tail, pine chrysanthemum, leopard skin flower, sedum, when the temperature reaches above 35 ℃, stop fertilization to avoid decay.
3. Pruning, picking buds
⑴ pruning Lang elm, Finch plum, Luo Hansong, Fujian tea, real cypress, juniper, bayberry, round cypress, wolfberry, holly, triangular maple snow willow, Tamarix, firethorn and other kinds of vigorous growth, the branches that affect the shape should be pruned or shrunk as soon as possible, so that the plant can maintain a hierarchical and good appearance, and can promote it to draw more short branches, send more new buds, and form a perfect shape as soon as possible.
When ⑵ picks buds from Milan, jasmine, magnolia, rose and other flowers, the abortive stems of the remnants should be removed in time, and the branches that have flowered should be properly shrunk so as to promote the lower side branches or flower buds to bloom again. In order to promote the flowers and trees such as Magnolia, daidai, rhododendron, camellia, wax plum, plum blossom and begonia to form a good plant shape, in the same year or in the coming year, more pregnant flowers, more blossoms and good flowers, those branches that are too prosperous should be topped and budded to inhibit the growth of the main and lateral shoots and promote the germination of lateral buds.
4. Shade
In June, those flowers and trees that like shade or semi-shade must be moved to the shade to prevent the sun from causing damage to the plants. Such as Hosta, purple calyx, asparagus, camellia, tea plum, rhododendron, orchid, orchid, palm bamboo, rubber tree, fern, forest taro, fruit taro, pink daiye, spring feather, green apple, bean green, green giant, red (green) gem, green emperor, red queen, sunflower, Ruixiang, one-leaf orchid, hanging orchid and so on. Flower species that like light must be given sufficient light, such as pomegranate, wisteria, Firethorn, crape myrtle, jasmine, June snow, cycad, cypress, peach blossom, plum blossom, wax plum, elm, Fujian tea, triangular maple, sparrow plum, wolfberry bone, holly, water bayberry, oak, black pine, brocade pine, Bailan, Milan, rose, ten meritorious works, grapes and so on. Luohansong, tiger thorn, bamboo, Buddha belly bamboo, Guanyin bamboo, five-needle pine, bamboo and cypress, etc., can be given appropriate shade.
5. Prevention and control of diseases and pests
⑴ cypress, cypress, elm, papaya, pyracantha, Luohansong and begonia are easy to be harmed by longicorn beetles, so poison label should be used in time to prevent and cure them.
⑵ rose, etc., are prone to powdery mildew and brown spot in the rainy season, so it is necessary to spray Bordeaux solution as soon as possible.
⑶ Magnolia, plum blossom and wax plum are easy to be harmed by aphids, so it is necessary to choose appropriate pesticides as soon as possible.
The leaves of ⑷ orchids are easy to be infected with anthracnose, so carbendazim and other fungicides should be sprayed as soon as possible.
⑸ daidai, lemon, kumquat, bergamot, etc., tender leaves are easy to be eaten by citrus butterfly larvae, can be sprayed with contact agents, stomach poisons and other pesticides to kill.
Fourth, bonsai modeling

Flower planting Handbook (July)
Weather characteristics in July: on July 7, the Meiyu weather ended in the Jianghuai region. Ambush on July 16 and ambush on August 15, most parts of the country entered the hottest period of the year. The monthly mean temperature in July is more than 24 ℃ in most parts of China and 28 ℃ in the south of Jianghuai. Only the average temperature in the north of Northeast China and Qinghai-Xizang Plateau is below 20 ℃. The management of flower affairs in July mainly includes the following contents: first, flower reproduction. The grass flowers that can be sown in July are: melon and leaf chrysanthemum, spring of the four seasons, kale, bluebells and so on. When sowing, we should pay attention to moisturizing, shading and increasing ventilation and light transmission. In July, mature fruits such as plum, hairy peach, mountain peach and elm leaf plum can be picked, washed and sown, or the washed drupe can be stored in wet sand to the crack before sowing. Wintersweet seeds can be sowed as they are picked, and the seeds removed from the fruit sac can also be dried and stored for sowing in the following spring, which will not affect its germination rate. two。 The species of grass flowers suitable for cutting propagation in July are: Scutellaria barbata, begonia, colored leaf grass, cold water, red, marigold, peacock grass, thousand-day red, geranium, Dutch chrysanthemum, chrysanthemum, umbrella grass, wall-climbing tiger, coral flower, pepper grass, unicorn leaf, fire charcoal mother, ground rooting, green pineapple and so on.

Rubber tree, Qionghua, Tianmu Qionghua, yellow poplar, Yuanhua fruit, purple magnolia, sweet-scented osmanthus, rhododendron, camellia, tea plum, dragon claw willow, golden willow and so on. Guding flower can also be cut with scales. In addition, some flowers and trees can be propagated by water insertion in July. They are: gardenia, oleander, rose, jasmine, pearl orchid, fig, pomegranate, inverted golden bell, crape myrtle, hibiscus and so on. To propagate flowers and trees by water cutting, one is to have a foam plastic board with a thickness of 1cm to 2cm, which is used as a cutting fixing material after perforation; the other is to keep the water quality of the cutting water clean and put a few pieces of charcoal into it for anticorrosion. 3. Grafting can use annual mountain peach and hairy peach sowing seedlings as rootstocks, bud propagation of blue peach, Shouxing peach, red leaf peach, plum blossom, elm leaf plum, red leaf plum, beautiful plum, etc.; using the cutting seedlings of wild rose, pink rose and "ten sisters" as rootstocks, budding breeding varieties such as rose, cut rose and rose; using potted Magnolia and Magnolia seedlings as rootstocks, * breeding white orchids, Michelia, etc. The 2-year-old seedlings of Chimonanthus praecox in potted plants are used as rootstocks, and the fine varieties of Chimonanthus praecox are propagated. The seedlings of 2-year-old Chimonanthus praecox can also be used as rootstocks, and the method of bagging and moisturizing with twigs can be grafted at 3 cm to 4 cm above the ground, and the survival of rhododendron can be judged after 7 to 10 days. "Purple Butterfly" and "Jade Butterfly" in rhododendron are used as rootstocks to propagate Belgian rhododendron or rhododendron by split or abdominal grafting. The cherry blossoms of fine varieties were propagated by budding with cherry seedlings as rootstocks, and the seedlings of the same year's seeds of Bauhinia mandshurica, Hubei Begonia or Tripterygium and Begonia as rootstocks were grafted with T-shaped buds to breed excellent varieties of Begonia. Acer maple seedlings were used as rootstocks to propagate red maple, feather maple and other seedlings by bag grafting. 4. The types of flowers and trees that can be reproduced by striping in July are: Milan (high pressure), wax plum, honeysuckle, eight immortals, Lingxiao, Qionghua, oleander, brocade, broom, sweet-scented osmanthus, gardenia, purple magnolia, jasmine, pearl orchid, Fujimoto rose, spring welcome and so on. 5. The ornamental plant species of feasible ramet in July are: Hosta, purple calyx, calamus, umbrella grass, one-leaf orchid, purple back evergreen, pineapple, twelve volumes, hanging orchid, Ophiopogon, auspicious grass, onion orchid, kidney fern, iris, hanging bamboo plum and so on. Second, harvest seeds and transplant 1. The grass flower seeds that can be harvested in July are hollyhock, sunflower, morning glory, summer grass, petunia, fluke, Digitalis, snake chrysanthemum, sweet pea, daisy, swallows, pansy, pine chrysanthemum and so on. The seeds of flowers and trees that can be harvested in July are: wax plum, plum, hairy peach, mountain peach, elm leaf plum and so on. two。 Transplanting and potting in July is the main time period for Chen to put grass flowers on the pot during the National Day. At this time, the grass flowers transplanted on the pot can be sowing seedlings or cutting seedlings. After three months of careful maintenance, they bloom just during the National Day period for festive decoration. They are mainly: a string of red, early chrysanthemum, thousand-day red, Xiaoli, Guinean impatiens, Longkou flower, marigold, peacock grass, ground skin, chrysanthemum, sulfur chrysanthemum, cockscomb and so on. Tree transplanting is generally not carried out in July, but in some special cases, it is also feasible to transplant some flowering shrubs with soil balls, such as ten meritorious works, hypericum, golden leaf privet, red leaf Berberis, peach leaf coral, dragon cypress ball and so on. However, it is necessary to prune pertinently, set up a shed for shade in time, and increase the number of water spraying, and then transfer to normal management after its basic survival. We must not be careless. Third, flower management 1. The flower species that enter the semi-dormant state when watering at high temperature, such as safflower sorrel, geranium, inverted golden bell, gentleman orchid, calla lily, begonia, sedum, longevity flower, cactus, crystal cactus, big flower rhino, emerald bead, big string moon, Daphne, crab claw orchid, purslane, aloe and so on, their growth activities basically stop and their metabolic level is very low, so watering should be reduced to keep the basin soil moist. And pay attention to shading and ventilation to create a relatively cool environment. If too much watering, it is easy to lead to rotten roots, but also seriously affect the recovery of its growth after autumn. The species of flowers that entered deep sleep at high temperature, such as cyclamen, Lycoris, buttercup, purse peony and so on, showed that the aboveground stems and leaves withered, the underground nutrient fibrous roots withered, and spent the summer dormant in the soil with underground stems or tubers. For deep dormant flowers, stop watering, move to a cool place, and keep the pot soil not too dry. For exuberant flower species, especially foliage plants, such as cycad, Magnolia, tortoise back bamboo, rubber tree, Magnolia, jasmine, Milan, pearl orchid, southern sequoia, bamboo taro, taro, red (green) gemstone, hulk, green emperor, green queen, pink leaf, Brazilian iron, rich tree, camellia, tea plum, peach leaf coral, torch fruit, daidai, lemon, Luohan pine, pomegranate, bauhinia, wisteria, rose, etc. It is not only necessary to increase the amount of water and times of watering, but also to give foliar spraying water and the combination of spraying and pouring properly. Especially when it comes to continuous cloudy days, due to the high temperature and dry air, it is also necessary to give watering and spraying, and must not be negligent. Once it is found that the basin soil is too dry and the leaves wilt, water should be sprayed on the leaves first, and then the roots should be watered after the leaves are erect again. Do not water the roots violently, otherwise it is very easy to cause the woody flowers to "fall green leaves", or lead to the rot of the vegetative fibrous roots of the plants, or even cause the death of the plants. For potted plum piles, as the flower bud differentiation period is from July to August, appropriate "buckle water" should be given to promote the normal differentiation of flower buds. The method is to keep the leaves of pot plants curled inward slightly in order to control vegetative growth; if the vegetative growth of branches can not be controlled, only one leaf at the base can be cut off when 2 or 3 leaves are pulled out from the second shoot, and flower buds can still be differentiated in the axils of this leaf. In July, watering potted flowers should avoid a few hours before and after noon, and it is appropriate to water before 10:00 and after 4 p.m., so as not to affect the growth of potted ornamental plants. If you encounter continuous rain this month, you should check the flowerpot in time after the rain, pour it when you find stagnant water in the flowerpot, and loosen the soil once after the pot soil dries up, so as not to cause rotting roots of potted plants. two。 There are four types of ornamental plants that should be strengthened in July. First, the flowering period is particularly long, from spring and summer to autumn, such as Magnolia, rose, Milan, jasmine, etc.; second, the species of autumn flowers, such as chrysanthemum, sweet-scented osmanthus, hibiscus, etc.; third, the species of viewing flowers and fruits in winter, such as hawkdai, bamboo, wax plum, rhododendron, etc.; fourth, foliage plants, such as brown bamboo, tortoise back bamboo, spring feather, rubber tree, and so on. For the first three types of fertilization, in addition to the necessary nitrogen fertilizer, appropriate amount of phosphorus and potassium fertilizer should be applied to meet the overall needs of plants for nitrogen, phosphorus and potassium, and to provide adequate nutritional guarantee for their budding, flowering and fruit hanging; for foliage plants, it should be based on thin cake fertilizer or urea. In the method of fertilization, it is better to apply thin liquid fertilizer. The grass flowers that should be fertilized in July are: a bunch of red (white, purple, pink), cockscomb, chrysanthemum, hundred-day red, thousand-day red, chrysanthemum, black chrysanthemum, petunia, golden bracts, shrimp flowers, Jianlan, marigold, purple jasmine, longkou flower and so on. Woody flowers are: crape myrtle, pomegranate, poinsettia, Michelia, sweet-scented osmanthus, camellia, tea plum, Fusang, jasmine, Prynne, Milan, evening incense, rose, begonia, mandarin duck jasmine, triangular plum, rhododendron, pearl orchid, wax plum, hibiscus, hibiscus, hibiscus and so on. There are many kinds of foliage plants, such as pineapple, Brazilian iron, brown bamboo, southern fir, synthetic taro, bamboo taro, hulk, ruby, cycad, rubber tree, tortoise back bamboo, Zhu banana and so on. In July, fertilization must be stopped for dormant or semi-dormant ornamental plants, especially for those succulent ornamental plants, such as sedum, fairy pen, pine chrysanthemum, leopard skin flowers, etc., to prevent plant decay. 3. The ornamental plants that can be pruned and picked in summer must be species with exuberant growth, strong germination and resistance to pruning. Heart-picking refers to the direct removal of tender tip buds with fingers. The main bonsai plants suitable for heart-picking are: hammer elm, sparrow plum, Chinan, silk cotton wood, melon seed yellow poplar, wax plum, firethorn, Luohan pine, Tamarix, Elaeagnus angustifolia, banyan tree, white wax, maple, crape myrtle, June snow, Jiuli incense and so on. Pruning refers to the use of scissors to trim off part of the new shoot to promote the germination of the lower lateral buds to form a beautiful crown or tree shape. Most of the species of bonsai plants suitable for pruning are woody ornamental plants that are not easy to pick with their fingers, such as juniper, Platycladus orientalis, Sabina vulgaris, cedar, oak, cat thorn, cypress and so on. For those potted flower species that bloom continuously for a long time, such as Milan, rose, jasmine, pearl orchid, etc., the stump should be picked in time, and the branches that have flowered should be shrunk in time, which can promote the germination and re-flowering of the lower lateral buds, while for rhododendron, camellia, tea plum, begonia, wax plum, plum, etc., the overlong branches of the crown should also be shrunk in order to form a better crown shape. 4. Shading July is the month with the strongest sunshine and the highest temperature of the year, so special attention should be paid to shading management for potted ornamental plants. For those ornamental plants that like shade or semi-shade, they must be placed under the shade to avoid damage to plants caused by the scorching sun. Such as ferns, hairpins, purple calyx, tortoise back bamboo, camellia, tea plum, rhododendron, pearl orchid, crane orchid, orchid, palm bamboo, rubber tree, red (green) gem, spring feather, pink leaf, green apple, pepper grass, orchid, hanging bamboo plum, Brazilian iron, unicorn leaf, pineapple, bamboo taro, auspicious grass and so on. For the species that like the light, you can give enough light, such as pomegranate, wisteria, crape myrtle, pyracantha, jasmine, June snow, cycad, round cypress, Platycladus orientalis, peach blossom, plum blossom, wax plum, hammer elm, sparrow plum, triangular maple, black pine, bayberry, oak, golden pine, blue orchid, Milan, rose and so on. On the other hand, it is necessary to give proper shade to Luo Han pine, bamboo and cypress, Michelia mollissima, tiger thorn, cloud bamboo, Guanyin bamboo, five-needle pine and so on. For small, miniature and shallow bonsai, because the temperature is too high this month and the air is relatively dry, in addition to giving necessary shade, flowerpots must also be buried in wet sand, which can reduce evaporation on the surface of potted soil and help to protect the nutrient fibrous roots of plants. 5. If the flowers in the air-conditioned room are air-conditioned, you should choose flowers with a higher degree of leatherization, or the leaves are covered with a thicker stratum corneum, slightly resistant to dry environment, and more resistant, such as rubber tree, star anise plate, Ten Gong Lao, cycad, southern fir, golden sunflower, sunflower, palm bamboo, Canadian jujube, pineapple, spring feather, tortoise back bamboo, goose palm wood, one-leaf orchid, peach leaf coral and so on. It is not suitable to choose kidney fern, colored leaf grass, hulk, taro and so on. In addition, in the management, attention should be paid to the combination of watering and spraying, and away from the air outlet of the air conditioner, so as to prevent the wind from directly attacking the plant, resulting in the withered tip and scorched edge of the leaves. 6. Disease and pest control ⑴ orchid new buds in July, the leaf tip is easy to be infected with anthracnose, gradually spread to the whole plant, serious will lead to plant withering and death. The disease may occur all the year round, poor ventilation, high temperature and humidity, continuous rain, more conducive to the reproduction and spread of bacteria. Ventilation should be strengthened and 75% of chlorothalonil wettable powder 800 times or germicidal Dan 500 times should be sprayed during the onset period for prevention and treatment. ⑵ when plum blossom, peach blossom, begonia, red leaf plum, cherry blossom, elm leaf plum and other stumps or trunk, there is a reddish-brown sawdust feces accumulation, mostly caused by longicorn beetle larvae, which can be controlled by artificial killing, injecting inhalant pesticides, plugging poison labels, burying carbofuran and other methods, which can effectively kill the larvae in the trunk. Pay attention to the injection of pesticides, do not use dimethoate, omethoate and so on, in order to prevent drug damage. In July, ⑶ should timely control the wild borer of Euonymus tomentosa, Populus tomentosa, Populus tomentosa and Populus tomentosa. When the insect occurs seriously, it can gnaw off all the leaves. Once found, pesticides such as trichlorfon, dimethoate or permethrin can be sprayed in time. If a certain pesticide has been used for a long time, it has produced resistance and can be changed to a new type of pesticide. In July, some areas of ⑷ will continue to see the leaves of citrus butterfly larvae harming new shoots, such as daidai, kumquat, golden bean, bergamot, lemon, fragrant circle, rue and so on. ⑸ harms ash insects of Ligustrum lucidum, Ligustrum lucidum, water wax and ash trees. The emergence period is from late July to late August. It is necessary to choose the right time to spray pesticides such as quick culling to prevent the disease from happening again in the coming year. ⑹ Japanese tortoise wax scale is the main pest that harms Populus tomentosa, Fawu, Haitong, Camellia, red leaf plum, cedar and so on. When it is serious, it is often covered with branches and leaves. The nymph hatching period is in the first ten days of July, which can be controlled by spraying dimethoate and quick killing pesticides in time. Fourth, bonsai modeling in July, due to high temperature, low air humidity, and plants are in a period of vigorous growth, it is not easy to recover from infection after branch injury, so most tree stumps are no longer suitable for flat binding. Still can carry on the modelling is some adaptable, tolerant plant species, and the request is the spring pot refines the seedling or the plant planted on the ground. They are: Yingchun, Ginkgo biloba, Luo Hansong, Luo Hanbai, Cuibai, June snow, black pine, melon seed yellow poplar, bayberry and so on. In July, the modeling of the plant should be careful, light and slow, slowly, not eagerly, too hard, otherwise it is easy to cause the branch and stem of the plant to break, endangering its survival. Solar terms in mid-July: Lesser Heat on July 7; Greater Heat on July 23.

In addition, Lycoris radiata, calla lilies and freesia can also be planted this month. Management of flowers planted in the courtyard 1. Transplanting. For some flowering shrubs with large soil balls and intensity pruning in August, the management of shading, watering and spraying should be strengthened after transplanting, and a higher survival rate can be obtained. Such as Golden Leaf Privet, Red Leaf Berberis, Platycladus orientalis in Phnom Penh, Golden Heart (side), Yellow Poplar, Hypericum, Ten Gongfu, Illicium platinum, Rose, Rhododendron, Gardenia jasminoides, Luo Han Song, smile, Dragon Cypress Ball, Shu juniper Ball, Yellow Poplar Ball, Pomegranate, hibiscus, Peach Leaf Coral, French Holly and so on. In the courtyard, you can also transplant fixed grass flowers, such as a string of red, thousand-day red, marigold, cockscomb, peacock grass, longkou flower, etc., which are expected to bloom in September and October. 2. Trim. In August, the hedges in the courtyard, such as boxwood, lobular privet, privet, golden leaf privet, French holly, spinulosa heather, etc., should continue to be pruned. Balls planted on the ground, such as heather, dragon cypress, Shu juniper, bayberry, pyracantha, Haitong, wolfbone, holly, etc., must also be pruned. For flowers and trees that bloom continuously for a long time, such as rose, pomegranate, hibiscus, crape myrtle, Fusang, triangular plum, five-color plum, etc., the residual flowers should be picked in time, and the branches and tips should be appropriately shrunk. Grass flowers planted on the ground, such as a string of red, thousand-day red, early chrysanthemum, peacock chrysanthemum, marigold, etc., should be topped and picked from the heart. 3. Watering. In August, watering and spraying management should be strengthened for flowers and shrubs transplanted in spring and grass flowers planted in spring. Plants with grass ropes tied to the tree trunk should be sprayed wet to ensure that the plants do not wilt new shoots and tender leaves, and should be sprayed and watered carefully to ensure that the roots do not accumulate water. 4. Fertilizing. Safflower planted on the ground in August? Wood, Phnom Penh (heart) boxwood, red leaf Berberis, golden leaf privet, purple leaf dwarf cherry, variable leaf wood, red mulberry, sprinkled golden peach leaf coral, flower leaf colorful alpinia officinalis, etc., in order to keep its leaf color bright for a long time, quick-acting fertilizer with a balance of nitrogen, phosphorus and potassium should be applied. For species that continue to bloom, such as rose, cinnamon, cinnamon, pomegranate, hibiscus, crape myrtle, leaf flowers, dahlias, and five-colored plums, as well as those that will bloom, such as sweet-scented osmanthus, chrysanthemum, hibiscus, autumn peony, etc., we should promptly apply an appropriate amount of available phosphorus and potassium fertilizer. For camellia, tea plum, plum blossom and wax plum which are in flower bud differentiation, a small amount of potassium dihydrogen phosphate can be sprayed by foliar topdressing. 5. Prevention and control of diseases and pests. In August, scale insects on cedar, privet, Haitong, sweet-scented osmanthus, crape myrtle, heather, camellia and other plants should be promptly sprayed with 1500-fold solution to control.

For those ornamental plant species that like acidity, 0.1% ferrous sulfate can be added to the irrigation water. It is worth noting that for ornamental plants with dense hairs on their leaves, such as Baobao, Tripterygium, Tripterygium, Begonia, etc., the leaves are not easy to evaporate after droplets, which can easily lead to leaf rot, and only a small amount of spray is feasible; the flower buds of Fulang flower (African chrysanthemum) and the leaf center of Magnolia can not be drenched with water, and the flow of dirty water into the leaves will cause heart damage. Pineapples must be watered less, sprayed more, and injected water into the leaf tube in order to meet their needs. When watering and spraying potted plants this month, you must pay attention to loosening the soil, but every 10 days, otherwise it will lead to pot soil hardening due to repeated watering. For dormant and semi-dormant flower species, watering and spraying should be controlled to keep the basin soil slightly moist, and a relatively cool environment can be created by spraying water around the flowerpot. 2. Fertilizing. In August, foliage plants Such as tortoise back bamboo, one-leaf orchid, rubber tree, spring feather, brown bamboo, red (green) gemstone, southern sequoia, golden wasabi, beautiful needle sunflower, sunflower, fishtail sunflower, sunflower, green apple, Brazilian wood, Dutch iron, fortune tree, kidney fern, dew tree, ash wood (African jasmine), orchid cinnamon (peace wood), gold coin tree (dragon and Phoenix wood), taro, green emperor, green queen, poinsettia, pink leaf, goose palm wood, peach leaf coral, green queen Pocket coconut, leafy wood, star anise gold plate, etc. Can be applied with low concentration of liquid fertilizer, such as urea, flower special fertilizer or cake fertilizer.

For potted grass flowers blooming in autumn, such as red, thousand-day red, dry chrysanthemum, marigold, peacock grass, longkou flower, chrysanthemum, chrysanthemum, pocket sunflower, etc., thin liquid fertilizer can be applied every semimonthly to ensure the reproduction of leaves and flowers after autumn. For the species of flowers and trees in flower bud differentiation, such as camellia, tea plum, plum blossom, sweet-scented osmanthus, rhododendron and so on, low concentration of phosphorus and potassium fertilizer should be applied to the leaves. When applying organic fertilizer to ornamental plants, do not drop the fertilizer on the leaves, so as not to cause the leaves to rot. For the sake of safety, spray water on the leaf surface in time after fertilization to rinse away the fertilizer droplets that may adhere to the leaves. For ornamental plant species in dormant or semi-dormant state, such as orchid, crabapple, calla lily, cyclamen, Daphne, aloe, longevity flower, purslane, crab claw orchid, sedum, purple triangle leaf sorrel, cactus, cactus, etc., it is necessary to stop all forms of topdressing, otherwise it is easy to lead to rotten roots or death. 3. Shade. In August, the heat is still strong, so it is still very important to manage the shade of potted flowers in the courtyard. For those cool ornamental plant species Such as tortoise back bamboo, spring feather, cherry angel, rubber tree, hulk, hulk, taro, taro, red (green) gemstone, brown bamboo, green apple, green emperor, green queen, bluegrass, pink daiye, pepper grass, pineapple, water mass flower, mirror grass, fern, Buddha belly bamboo, Phoenix tail bamboo, hanging orchid, auspicious grass, pocket coconut, netted grass, purple velvet, blood leaf orchid, silver silk grass, black leaf Guanyin lotus, crystal candle, anthurium, anthurium Begonia, rich bamboo, one-leaf orchid, asparagus, purple calyx, etc. Can continue to give shade, pull up the shade net at 9: 00 in the morning, and then withdraw after 4: 00 in the afternoon. If the number of potted flowers is small, they can also be moved indoors for 6 to 7 hours before and after noon. If there are conditions, you can also move it to the shade of big trees and wait until the middle of September to move out from the shade of trees. 4. Trim. In August, those stump bonsai that are vigorous, pruning-resistant and easy to germinate continue to be heart-picked or trimmed, such as hammer elm, Finch plum, Fujian tea, banyan tree, white wax, bayberry, melon seed and yellow poplar. Cut the rose, pomegranate, Milan and so on after each flower. For potted chrysanthemums, it is necessary to do a good job of sprouting and bud removal? BR > 5. Control diseases and insect pests. In August, scale insects, citrus butterflies, rose leaf wasps, peach red-necked longicorn beetles and other pests should be controlled. Pay attention to the prevention of orchid leaf diseases, including anthracnose, Botrytis cinerea, leaf blight and so on. Pay attention to the control of chrysanthemum aphids, leaf moths, borer and so on. Potted plants suitable for balcony display in August, the balcony is still hot and dry, and only some potted ornamental plants with strong resistance or long-term shelving on the balcony can adapt. Such as black pine, brocade pine, five-needle pine, hammer elm, Finch plum, water bayberry, wolfberry, holly, wax plum, fruit pomegranate, pomegranate, melon seed yellow poplar, Platycladus orientalis pile, round cypress, ground cypress, oak, white wax, Fujian tea, rose, leaf flower, tequila, five-colored plum, ginkgo, jasmine, Milan, triangular maple, Luohan pine and so on. In August, some of the flowers and trees on the balcony can be transferred to air-conditioned rooms. Such as Cymbidium, Dendrobium, Cartland, Orchid, Orchid, Oncidium, South American iron tree, black leaf Guanyin lotus, crystal candle, red palm, hulk, red (green) gemstone, taro, sunflower, king coconut, cherry, tortoise back bamboo, orchid, green apple, palm bamboo, rich tree, gentleman orchid, inverted golden bell, reticulate grass, golden bract, Brazilian wood, star anise plate and so on. The propagation of flowers on the balcony in August, large diameter flowerpots can be used on the balcony, covered with plastic film, moisturizing and cutting some ornamental plants, and the cutting substrate can be mixed with rice bran ash and fine sand in the ratio of 2 ∶ 1, or vermiculite can be used alone. Some ornamental plants can also be inserted indoors, but the water must be changed frequently, such as rose, gardenia, jasmine, pearl orchid, goose palm wood, peach leaf coral, figs, plantains, Burmese gardenia, geraniums, Guangdong evergreen, hanging golden bell and so on. Balcony flower management 1. Watering. The watering and spraying of potted flowers on the balcony in August should be careful. For Cymbidium, Cymbidium, Oncidium, Cartland, inverted Golden Bell, Dendrobium, Crystal Candle, Black Leaf Guanyinlian and so on, they can be moved to an air-conditioned room and watered instead of watered to ensure that they can spend the summer normally. For flowers that are more heat-resistant on the balcony, such as rose, Milan, jasmine, pomegranate, triangular plum, hammer elm, Finch plum, melon seed yellow poplar, triangular maple, black pine, Jinsong, wisteria, Fujian tea, bayberry, tequila, cycad, etc., can be watered once or twice a day and sprayed once or twice a day. 2. Fertilizing. In August, fertilizer should be stopped for potted plants on the balcony that are dormant and semi-dormant. For exuberant foliage plants, 0.3% urea can be sprayed or poured, or multi-component compound fertilizer particles can be applied on the basin. Flowers and trees that mainly watch flowers and fruits, such as Magnolia, Milan, pomegranate, crape myrtle, jasmine, daidai, firethorn, bergamot, kumquat, etc., should continue to apply quick-acting phosphorus and potassium fertilizer. For hammer elm, sparrow plum, wolfberry bone, holly, Luo Hansong, Fujian tea, triangle maple, bayberry, melon seed, etc., after each pruning, you can apply a thin fertilizer. 3. Shade. In August, potted plants shelved on the balcony to receive full light, especially shallow pot piles, such as five-needle pine, Luohan pine, cypress, Fujian tea, plum blossom, triangular maple, etc., can be covered with soft grass, moss or wet cloth on the potted surface, which can not only keep moisture and cool down, but also protect the nutrient fibrous roots distributed in the topsoil from harm. If the balcony is more spacious, sunshade nets can be used to block the light. If there are not many potted flowers and trees on the balcony and are relatively precious, it is best to move them indoors for 5 to 6 hours before and after noon. 4. Trim. In August, most of the stump bonsai shelved on the balcony, such as hammer elm, Finch, June snow, white wax, oak, small bayberry, triangular maple, banyan, Fujian tea, Platycladus orientalis, lobular privet, melon seed yellow poplar, firethorn and so on, still need to be picked or trimmed this month. The stump flowers, withered branches and yellow leaves on other potted ornamental plants should also be cut off in time. 5. Prevention and control of diseases and pests. In August, red spiders are the most vulnerable to red spiders on the balcony. 1500 times of 25% Baileba wettable powder should be sprayed and killed in time. A small number of scale insects on flowers and trees can be removed by pasting transparent glue. The aphids that often appear on chrysanthemums should be sprayed with 1000 times of trichlorfon crystals.

Management of flowers planted in the courtyard 1. Transplanting. As the temperature in September is still relatively high, it is not necessary to transplant flowers and trees in the courtyard. For example, for the layout of the new courtyard or the transformation of the old courtyard, transplanting can also be carried out on the premise of bringing a good earth ball. Species such as oleander, dragon cypress, Michelia, Shu juniper, sweet-scented osmanthus, camellia, red leaf Berberis, golden leaf privet, yellow poplar, hypericum, French holly, safflower? Wood, sprinkled golden peach leaf coral, etc. Transplanting should carry out intensity pruning, and strengthen watering, spraying and shading management in order to ensure that transplanting is foolproof. Some grass flowers can still be planted or potted for viewing in October in golden autumn. Species are: red, thousand-day red, marigold, peacock grass, longkou flower, chicken crown flower, Catharanthus roseus, sulfur chrysanthemum, Xiaoli, marigold, short canna, morning chrysanthemum and so on. 2.

It is appropriate to pick the heart every 10 days to promote it to form a plump plant shape, and give birth to more inflorescences on the lateral shoots, and stop picking the heart after late September. For woody flowers that bloom continuously for a long time, such as variety rose, abundant rose, miniature rose, rattan rose, crape myrtle, pomegranate, five-color plum, triangular flower, etc., the stump should be cut off in time, and the branches that have flowered should be appropriately shrunk to effectively promote them to blossom again. 3. Watering. In September, the climate is relatively dry, and continuing to do a good job in watering and spraying the trees and shrubs transplanted in the spring in the courtyard is one of the key measures to consolidate their survival effect. The first is to water the roots to keep the soil moist, but not to accumulate water; the second is to spray water on the grass rope wrapped around the trunk to create a locally moist protective layer for the trunk; and the third is to spray water on the crown to reduce foliar transpiration and increase the humidity of the local space. In addition, for the newly planted grass flowers, it is also necessary to do a good job of spraying water and moisturizing. 4. Fertilizing. Colorful foliage plants planted on the ground, such as golden leaf privet, red leaf Berberis, red maple, safflower? Wood, alpinia officinalis, alpinia mandshurica, golden peach leaf coral, red mulberry, red leaf dwarf cherry, red leaf plum, red leaf peach, etc., in order to keep its bright leaf color, phosphorus and potassium fertilizer should be applied properly.

In addition, there are seven-leaf trees, crape myrtle, cloves, begonia, bauhinia, rhododendron, yew, bright-leaf wax plum and so on. The seeds of Magnoliaceae, yew, seven-leaf tree, begonia, etc., must be stored in wet sand until early spring next year, and then sow in the field after the seed crack. The seeds of grass flowers that can be harvested are: marigold, zinnia, impatiens, purple jasmine, cockscomb, Catharanthus roseus, wheat straw chrysanthemum, emerald chrysanthemum and so on. Management of potted flowers in courtyard 1. Watering. In September, the light is strong, the temperature is high, and the air is quite dry, so the watering management of potted flowers can not be ignored. Watering times, for the general wet foliage plants, the first half of the month can be watered or sprayed once in the morning and afternoon, and watered once in the second half of the month, and give foliar spray water appropriately. For most potted flowers and bonsai, it can be watered once a day, supplemented by foliar spraying. Watering time is before 10:00 in the morning and after 3pm. For ornamental plant species that like acid environment, a small amount of 0.1% light green ferrous sulfate powder can be added to the irrigation water. For summer dormant or semi-dormant flower species that resume growth after autumn, the number and frequency of watering (or spraying) can be gradually increased. When watering potted plants, they should loosen the soil every half a month. 2. Fertilizing. September is the period of exuberant growth of most flowers, some dormant and semi-dormant flower species in summer, with the gradual cooler temperature, also began to restore growth, this month should attach great importance to fertilization management. For foliage plants, such as tortoise back bamboo, rubber tree, wealth tree, Brazilian wood, spring feather, brown bamboo, ash ash, cinnamon, money tree (dragon and Phoenix wood), Nanyang fir, fish tail sunflower, green apple, red (green) gem, green emperor, silver queen, bamboo taro, synthetic taro, fir, etc., it is still dominated by low concentration of light fertilizer, such as 0.3% urea, etc. For flowers and trees with special flowering or full flowering in autumn, such as rose, tricolor plum, five-colored plum, pomegranate, crape myrtle, Milan, blue blue, jasmine, four seasons cinnamon, cinnamon, sweet-scented osmanthus, etc., ornamental plants such as daidai, Phyllostachys pubescens, cinnabar root, firethorn, papaya, golden marbles, purple beads, fruit pomegranate, etc., colorful leaf plants such as variable leaf wood, gold-sprinkled peach leaf coral, pineapple, flower leaf banyan, Phnom Penh Brazil wood, Zhu banana, colored leaf grass, etc. Fertilizer types with balanced application of nitrogen, phosphorus and potassium should be applied. For the resuming growing crabapple, geranium, calla lily, cyclamen, four seasons begonia, Daphne, crab claw orchid, sedum, purslane (jade leaf), purple triangle leaf sorrel, gentleman orchid, arrow lotus, etc., low concentration liquid fertilizer can be restored. For flowers that have completed flower bud differentiation and entered the stage of flower bud expansion, such as Camellia, Camellia, Chimonanthus, Plum, Michelia, rhododendron, etc., low concentration nutritionally balanced fertilizers can be applied to potted grass flowers, such as red, marigold, chrysanthemum, chrysanthemum, dahlia, pocket sunflower, etc., thin fertilizer can be applied every 10 days to meet the needs of their pregnant buds and next month's flowering. 3. Shade. In September, the temperature is high and the sun is still strong, so the shading management of potted flowers in the courtyard can not be relaxed. For those species of foliage plants that like shade Such as tortoise back bamboo, rubber tree, kidney fern, Boston fern, bird's nest fern, synthetic taro, taro, green apple, brown bamboo, green emperor, silver queen, orchid, pink daiye, golden horseradish, orchid, autumn begonia, unicorn leaf, cherry, red (green) gemstone, crystal candle, black leaf Guanyin lotus, reticulate grass, red vein jade bed, asparagus, goose palm wood, flower leaf Phoenix tail fern, watermelon pepper grass, flower and leaf evergreen, green giant, red palm, red palm Antler fern, mirror grass, water mass flower, emperor sunflower, rich bamboo, etc. Give 5 to 6 hours of light a day through shade Full light can be given to the species that like light, such as triangular maple, hammer elm, Fujian tea, ginkgo, bayberry, black pine, Platycladus orientalis (pile), round cypress, crape myrtle, southern fir, wisteria, Milan, jasmine, fire thorn, rose, oak, white wax, etc. Wood, epiphyllum, Phyllostachys pubescens, Yushu, rhododendron, camellia, tea plum, bergamot, daidai, kumquat, etc., can be given appropriate shade around noon. The newly transplanted autumn grass flowers should also be shaded properly to prevent the plant from wilting and affecting its growth. 4. Trim. For potted chrysanthemums, we should continue to peel off buds and remove buds, and prune rose, pomegranate, Milan, jasmine, pearl orchid, triangular plum, five-colored plum, golden bract, coral flower and so on after each flowering. For those tree stump bonsai species that are resistant to pruning, easy to germinate and thrive, such as hammer elm, sparrow plum, triangular maple, Fujian tea, banyan tree, red nan, lobular privet, bayberry, melon seed yellow poplar, Platycladus orientalis (pile), true cypress, white wax, Tamarix, etc., continue to prune or pick buds. In addition, the seedlings of the rich trees can be braided and put on the pot. 5. Pest control. The red-necked longicorn beetles on potted plum blossom, begonia, Birthday Bun with Bean Paste Filling, green peach and other plants can be injected with poison and can also be controlled by burying carbofuran granules. The Japanese tortoise wax scale, cotton blowing scale, shield scale, velvet scale and so on appeared on potted flowers and trees were controlled with 1500 times liquid of 40% speed culling. Potted plants suitable for balcony display in September, the balcony is still strong light, dry air, only some long-term put on the balcony potted flowers or potted plants with strong resistance, can adapt to the special environment on the balcony. They are: black pine, golden pine, red pine, five-needle pine, hammer elm, Finch plum, bayberry, triangular maple, wolfberry, holly, wax plum, pomegranate, melon seed yellow poplar, Platycladus orientalis (pile), round cypress, Fujian tea, white wax, banyan, leaf flower, rose, tequila, ginkgo, Milan, jasmine, park tree, Luo Han pine, thorn, five-colored plum and so on. For some flower species that prefer a cool environment, they can continue to be placed in air-conditioned rooms, such as Cymbidium, Oncidium, Dendrobium, Cartland, Wandai Orchid, Spider Orchid, Black Leaf Guanyin Lotus, Crystal Candle, Anthurium, Gentleman, inverted Golden Bell, Reticulate Grass, etc. For some common foliage plants, they can be moved indoors in 4 to 5 hours before and after noon, such as brown bamboo, tortoise back bamboo, Brazilian wood, rich tree, green apple, one-leaf orchid, loose-tailed sunflower, fish tail sunflower, king coconut, spotted oak tree, sprinkled peach leaf coral, goose palm wood and so on. The breeding of flowers on the balcony in September, you can continue to use large-caliber flowerpots as containers on the balcony, with a mixture of bran ash and wet sand accounting for 1 and 2 respectively, moisturizing with plastic film, and can be cut and propagated some ornamental plants, such as gardenia, plantain, sprinkled peach leaf coral, goose palm wood, Japanese cinnamon, four seasons cinnamon, camellia, tea plum, pearl orchid, jasmine, red back cinnamon, coral, golden bract, smile, silver bright silk grass and so on. You can also insert goose palm wood, rose, gardenia, figs, Guangdong evergreen and so on in indoor water. Balcony flower management 1. Watering. For some ornamental plants that like wetting, such as Chunlan, Jianlan, Magnolia, tortoise back bamboo, one-leaf orchid, camellia, tea plum, cherry, pearl orchid, pineapple and so on, they can be put on the plank on the balcony pool or tank, or in the simple sand pool built by themselves, and usually spray water instead of watering. For potted foliage plants shelved indoors, they should also spray more water and less watering, so as to keep the pot soil loose and moist; especially in the air-conditioning room, spray water at least once or twice a day, otherwise even the five-needle pine bonsai, which is more drought-resistant, will lose water and die without watering or spraying for 5 to 7 days. Potted ornamental plants with strong resistance on the balcony can continue to be watered once a day and sprayed once or twice a day, or soaking pot method can be used to prevent the occurrence of wet and dry soil. Watering time should still avoid 2 to 3 hours before and after noon, pay attention to the difference between water temperature, soil temperature and air temperature, and add a small amount of light green ferrous sulfate to the irrigation water to avoid physiological yellowing. 2. Fertilizing. Low concentration liquid fertilizer should also be applied to potted flowers that gradually recover from dormancy or semi-dormancy; for potted pile heads with vigorous growth, dilute liquid fertilizer can be applied once after heart-picking and pruning; for potted flowers and trees that mainly view flowers and fruits, such as Magnolia, rose, pomegranate, crape myrtle, jasmine, pearl orchid, daidai, hot thorn, bergamot, kumquat, etc., we should continue to apply quick-acting phosphate and potassium fertilizer. For potted flowers that have completed flower bud differentiation and whose buds are growing, such as Camellia, Camellia, Chrysanthemum, Plum, Osmanthus, Chrysanthemum, etc., according to different species, appropriate amount of available phosphorus and potassium fertilizer or nitrogen, phosphorus and potassium balanced multi-component compound fertilizer can be applied. On the balcony to the kinds of flowers and trees topdressing, do not have a peculiar smell, especially can not have a bad smell, pouring attention to do not splash downstairs, careful operation. 3. Shade. For the stump bonsai and potted flowers shelved on the balcony to receive full light, in order to reduce watering, prevent soil hardening, and protect the nutritious fibrous roots distributed in the surface of the potted soil, you can continue to cover the potted surface with wet grass, moss, wet cloth, etc.; when the number of potted flowers is small, it can be moved indoors in 5 to 6 hours before and after noon; if there are more potted flowers and the conditions are available, you can continue to stand and pull up the sunshade to block the light. 4. Trim. In September, bonsai stumps placed on the balcony, such as hammer elm, sparrow plum, bayberry, melon seed yellow poplar, triangular maple, banyan tree, Fujian tea, Platycladus orientalis (pile), round cypress, cedar, lobular privet, white wax, etc., still need to be coring or pruning. The withered branches, yellow leaves and abortive stems of other potted flowers and trees should also be cut off in time. 5. Pest control. In September, when the temperature on the balcony is high and the air is dry, potted flowers and trees are most vulnerable to the harm of red spiders, which can be sprayed with 1500 times of 25% Begonia wettable powder. Longicorn beetles on dragon cypress, cypress and juniper bonsai, and pink-necked longicorn beetles on plum blossoms, begonia, papaya, Birthday Bun with Bean Paste Filling and other flowers and trees can continue to be injected with poison labels or buried with carbofuran for control. A variety of scale insects harmful to camellia, pyracantha, crape myrtle, wax plum and other flowers and trees can be artificially erased when the number is small, and can be sprayed with 1500 times of quick culling liquid to control when the number is large.

For continuously flowering flowers and trees in the courtyard, such as rose, crape myrtle, five-colored plum, triangulated plum, etc., we should continue to cut off the stump and stem, and cut the branches that have flowered moderately. For the grass flowers planted in the courtyard, such as red, marigold, thousand-day red, etc., it is necessary to cut off the open inflorescences in time to promote their lateral shoots to continue to blossom and blossom, so as to prolong the ornamental period.
3. Watering. For the newly planted courtyard flowers and trees in that year, we should continue to do a good job in watering and spraying: first, we should keep the soil at the roots moist, but there should be no stagnant water; second, we should continue to spray water on the leaves. In addition, we should also do a good job of spraying water and moisturizing the newly planted grass flowers.
4. Fertilizing. For autumn grass flowers planted in the courtyard, it is appropriate to apply balanced quick-acting fertilizer of nitrogen, phosphorus and potassium; for sweet-scented osmanthus flowers that have already bloomed, base fertilizer can be opened in annular trenches; for pruned rose, begonia, crape myrtle, hibiscus, camellia, Michelia, plum blossom, wax plum, etc., appropriate amount of compound fertilizer can be applied. For Phyllostachys pubescens and Firethorn, as well as bergamot, kumquat, daidai and golden marbles in the south, a small amount of available phosphorus and potassium fertilizer can be properly applied to prolong the fruit appreciation period.
5. Pest control. Stem borer pests such as plum blossom, red leaf plum, cherry blossom and begonia planted in the ground will continue to be controlled with poison swabs. The withered branches and leaves falling in the courtyard should be cleaned and burned in time.

In addition, at the end of October, the underground roots of canna and dahlia were dug up when the aboveground part was close to withering, and the sand was stored indoors, keeping the room temperature not less than 5 ℃, and then cut and planted again in the spring of next year.
Management of potted flowers in courtyard
1. Watering. Although the weather has turned cool, in most areas south of the Huaihe River, the temperature is still above 17 ℃, and the air is quite dry, so watering of potted flowers must be managed carefully. For some foliage plants that like to be moist, such as rubber tree, orchid orchid, tortoise back bamboo, green apple, synthetic taro, ash ash wood, orchid cinnamon, hulk, ruby, etc., it is appropriate to water once a day in sunny days, supplemented by foliar spray; for summer dormant flowers that resume growth after entering autumn, including semi-dormant species, such as calla lily, cyclamen, gentleman orchid, purslane, incense, geranium, hanging bell crabapple, etc., need to increase the amount of water. For wax plum, plum blossom and camellia that blossom in winter and early spring, watering should be controlled and more water should be sprayed to facilitate the expansion of the bud. For the cold-afraid flower species in the northern region, it is necessary to reduce watering, which can accelerate the Lignification of their new shoots, so as to facilitate their safe passage through the winter. The best watering time is 10:00 or 3pm.
2. Fertilizing. For summer dormant flowers that resume growth after cool autumn, it is necessary to apply low concentration quick-acting liquid fertilizer in time; for camellia, plum blossom, wax plum, melon and leaf chrysanthemum, primrose, gentleman orchid, cyclamen, cyclamen, Belgian rhododendron, red daffodil, etc., the mixture of 0.2% potassium dihydrogen phosphate and 0.1% urea should continue to be applied. For most foliage plants, the application of nitrogen fertilizer should be stopped after the middle of October, and some low concentration potassium fertilizer should be applied properly in order to increase the cold resistance of plants; for ornamental fruit potted plants, such as daidai, lemon, kumquat, Tianzhu, winter coral, rich seeds, golden marbles and so on, a small amount of phosphorus and potassium fertilizer can be applied in the first and middle of October.
3. Shade. For some very shady foliage plant species, such as Daifen leaf, tortoise back bamboo, bamboo taro, synthetic taro, emerald, Boston fern, pepper grass, etc., they still need to be shaded 2 to 3 hours before and after noon.
4. Trim. For most of the bonsai and potted flowers that must be moved indoors in the middle and late October, the withered branches, disease and insect branches, and thin branches should be cut off first; for the long branches, they should be shrunk in strength; the binding objects that have been modeled for 1 to 2 years can be removed, or they can be re-tied after they are untied, so that they will not be strangled and bound in a fixed position for a long time, injuring the cambium of the branches, causing the branches and leaves to die.
5. Keep out the cold. In the middle and last ten days of October in the northern region, some ornamental plant species that cannot tolerate the low temperature below 10 ℃ can be moved into the greenhouse in time; for some more hardy woody potted flowers or tree stump bonsai, they can be buried in the leeward and sunny soil at the end of the month to prevent the basin soil from freezing. The Yangtze River basin should accurately grasp the information of weather changes and avoid the threat of cold wave going south.
6. Pest control. Cut off the dead branches and leaves from potted flowers and trees, collect them uniformly and burn them. For potted chrysanthemums, aphids, chrysanthemum tigers, leaf miner larvae, inchworm and other pests should be controlled.
Potted plants suitable for balcony display
On the balcony in the first and middle of October, the light is strong and the air is dry. Only those potted flowers and trees that have been left on the balcony for a long time and have strong resistance can adapt to the open-air environment of the balcony. They are: black pine, golden pine, hammer elm, sparrow plum, triangular maple, water bayberry, white wax, Fujian tea, Luohan pine, Platycladus orientalis, round cypress, dragon cypress, melon seed yellow poplar, pomegranate, leaf flower, thick-leaf banyan, ginkgo, rose, jasmine, Milan, iron tree, firethorn, five-colored plum, Tamarix, red maple and so on. Some cold-resistant southern flowers and trees can no longer be placed on the balcony when the temperature drops to 10 ℃. For some flower species that like a cooler environment, they can be placed indoors at the beginning of the month. Such as Cymbidium, crystal candle, netted grass, Cartland, Phalaenopsis, Oncidium and so on. For some common foliage plants, they can be moved indoors in 3 to 4 hours before and after noon, and can be placed on the balcony at other times, such as palm bamboo, Brazilian wood, wealth tree, green apple, one-leaf orchid, loose-tailed sunflower, fishtail sunflower, king coconut, spotted cymbidium, goose palm wood and so on. In the north, when the temperature drops to 10 ℃, most flowers and trees can no longer be placed on the balcony. The propagation of flowers on the balcony in the first ten days of October, we can continue to use the wide-mouth flowerpot as the cutting container on the balcony, containing the mixed cutting substrate of 1% of bran ash and 1% of wet sand, or vermiculite can be used alone as cutting substrate, covered with plastic film to moisturize, and cuttings propagate a small amount of ornamental plants. Such as gardenia, goose palm wood, rubber tree, peach leaf coral, Michelia, jasmine, pearl orchid, Guangdong evergreen, coral flower, golden bract, shrimp flower, mulberry, bergamot, silver queen silk grass, golden kudzu, geranium and so on.
Management of balcony flowers
1. Watering. For woody ornamental plants placed on the balcony, such as cycads, banyan trees, rubber trees, goose palm wood, Brazilian wood, rich trees, Milan, Prynne, jasmine, etc., can be watered once a day, supplemented by foliar spray; for the already pregnant bud, the species that will blossom in winter and early spring, such as wax plum, plum blossom, camellia, tea, Belgian rhododendron, etc., should not be watered too much, and spraying the branches and leaves at the same time can effectively promote the expansion of the bud. For potted foliage plants shelved indoors, such as tortoise back bamboo, spring feather, cherry angel, one-leaf orchid, plantain, bird's nest fern, Anthurium andraeanum, taro, green apple, etc., should be watered mainly and watered as a supplement, in order to keep the basin soil dry.
2. Fertilizing. Potted flower species that resume growth from dormancy or semi-dormancy, such as Cymbidium, cyclamen, calla, and Cymbidium, pineapple, orchid, etc., can be poured with a mixture of 0.2% potassium dihydrogen phosphate and 0.1% urea; for fruit-viewing daidai, kumquat, kumquat, lemon, bamboo, golden marbles, rich seeds, hot thorns, winter corals, etc., can continue to apply a small amount of low concentration available phosphate and potassium fertilizer. For Milan, Magnolia, Pearl Orchid, Jasmine and so on, thin phosphorus and potassium fertilizer can be applied 1 or 2 times in early October to facilitate its smooth winter.
3. Shading. In the first and middle of October, in order to reduce the amount of water, protect the nutritious fibrous roots distributed on the surface of the potted soil, and prevent the consolidation of the potted soil, we can continue to cover the surface of the potted soil with wet grass, moss, wet cloth and so on, especially the shallow potted tree stump bonsai, in order to reduce the amount of water, protect the nutritious fibrous roots distributed on the surface of the potted soil and prevent the consolidation of the potted soil. For some shade-loving foliage plants, they can be moved indoors for 3 to 4 hours before and after noon in sunny weather. The sunshade net built in summer can be removed after mid-October.
4. Trim. The stump bonsai shelved on the balcony in mid-late October, such as hammer elm, sparrow plum, triangular maple, banyan tree, Fujian tea, Platycladus orientalis (pile), Luohan pine, round cypress, dragon cypress, privet, etc., must be pruned and reshaped as necessary. The wire or non-metal wire which has been bound for more than a year can be solved first. if the modeling requirement is not met, a new binding position can be changed and then fixed, so as to avoid serious damage to the plant caused by deep constriction. For general potted flowers and trees, such as rose, wax plum, plum blossom, pedicel begonia, vertical silk begonia, etc., can also be pruned appropriately.
5. Pest control. In late October, the dead branches and leaves of all potted flowers on the balcony can be collected and burned together. The stump bonsai with partially exposed xylem of the trunk can be smeared with stone-sulfur mixture, which can not only protect the xylem of the trunk, but also reduce the occurrence of diseases and insect pests in the coming year. Flower planting Handbook (November)

In winter, bamboo crabapple, borer leaf begonia, lotus leaf begonia, geranium, Fusang, hanging bell begonia, Yushu, purslane, red back cinnamon, golden bract, shrimp flower and so on can be cut and propagated in the greenhouse.
In November, ear cuttings such as hibiscus, Lingxiao and grape can be cut and stored in the Yangtze River valley, and cutting in the next spring can obviously accelerate the rooting speed and improve the survival rate of cuttings.
3. Grafting. Red maple and feather maple were grafted with green maple seedling as rootstock, red maple and feather maple were grafted with apricot seedling and peach seedling as rootstock, plum blossom was cut (grafting interface was buried in soil for overwintering), sturdy branches of rose (Elizabeth variety) were used as rootstock, branches of excellent rose were used as scion, split grafting or cutting were carried out after cuttage, interface healing and lower incision rooting were synchronized, which could speed up the process of cultivating grafted seedlings of rose.
4. Press the strip. The main species of flowers and trees that can be propagated under low pressure in November are: Tripterygium, Gardenia jasminoides, gardenia, pomegranate, camellia, plum blossom, wax plum, Luohansong, brocade flower, sweet-scented osmanthus, eight immortal flowers, purple magnolia, emerald cypress, Michelia, hemp leaf hydrangea, snowball, Qionghua, spray snow and so on.

Among them, when transplanting evergreen trees, the branches and trunk must be properly cut or truncated, and most of the leaves must be deleted, and the trunk should be tied up with grass rope, and at the same time, a large soil ball (generally the diameter of the soil ball is about 6 to 7 times the diameter of the trunk). To ensure its survival; transplanting deciduous trees, you can cut the trunk short, cut the big branches, bring the soil balls and tie up the trunk. After transplanting, the management of watering and trunk spraying must be strengthened in order to survive. In addition, the incisions of the trunk and big branches should be sealed with wax or bound with plastic film to prevent a large amount of water evaporation in the tree.
In November, plum piles, wax plums, camellias, camellias, camellias
In November, potted hyacinths, tulips and daffodils should be transferred to the greenhouse to promote them to blossom around the Spring Festival.
1. Water it. For most of the ornamental flowers (including bonsai) placed in the greenhouse, greenhouse or room, the amount of watering in November should be based on keeping the basin soil moist and should not be too wet. if the temperature is too low and the plants are watered too much, the roots are easy to die. If the indoor temperature is high, the amount of water should be increased appropriately, and the necessary foliar spray should be given.
For those species of potted flowers that bloom before and after the Spring Festival, such as camellia, tea plum, rhododendron, plum blossom, wax plum, melon and leaf chrysanthemum, as well as fruit ornamental plants such as dai dai, bergamot, lemon, firethorn, bamboo, winter coral, rich seeds, etc., not only to keep the potted soil moist, but also to spray water frequently to the plant, so as to facilitate the expansion and growth of the plant flower buds, and also make the fruit appear more colorful.
For foliage plants shelved in greenhouses, greenhouses and rooms, we should not only keep the basin soil moist, but also spray water on the leaves regularly to keep them green and clean all the time. In the greenhouse and living room with higher temperature, the amount of water can be increased. For less hardy foliage plants, such as taro, bamboo taro, pink daiye, green emperor, variable leaf wood, silver queen, etc., the amount of water should be controlled to help them survive the winter safely.
[page] the suitable watering time for potted flowers in November is from 10 am to 11:00, and the water temperature should be basically consistent with the soil temperature, so as to avoid adverse reactions caused by low water temperature, which will affect their safety in overwintering.
two。 Fertilize. For potted flowers shelved in the room above 15 ℃, such as rhododendron, camellia, camellia, plum blossom, wax plum, golden bract, shrimp flower, Rui Xiang, melon and leaf chrysanthemum, cyclamen, tapestry begonia, hyacinth, gentleman orchid, tulip, ornamental pineapple, crab claw orchid, colorful pineapple, etc., they can continue to apply low concentrations of phosphorus and potassium fertilizer, and 0.2% potassium dihydrogen phosphate fertilizer solution can promote their growth and flowering.
For most of the potted plants, foliage plants and bonsai placed in the general greenhouse, topdressing should be stopped to facilitate its normal dormancy and overwintering. Most of the flowers and trees planted on the ground, such as begonia, Magnolia, Michelia, Gardenia, seven-leaf tree, camphor, Spiraea, sweet-scented osmanthus, grape, rose, wax plum, plum blossom, cherry blossom, trouble-free, acacia, palm, red maple, peony, golden bell, peony, hypericum, etc., can be buried with biscuit fertilizer The dosage of each plant is 0.5 kg to 1.5 kg, and the smaller plants can be less, laying a good material foundation for the growth and flowering of next year.
3. Trim. Continue to trim hedges, green walls and ball shapes that have not been trimmed, and base fertilizer can be applied after pruning.
Carry out omni-directional shaping and pruning of bonsai plant species dominated by scissors, such as hammer elm, Fujian tea, Finch, maple, oak, white wax, fire thorn, June snow, cypress, Luohan pine, wintersweet, begonia, etc., to lay a good skeleton for next year's growth.
Pruning the ground or potted rose that has not yet been pruned, except for retaining 3 to 5 1-to 2-year-old sturdy stems with a base of 30 cm to 50 cm, the rest of the old stem is amputated from its base, and all the thin branches are cut off. The current year's branches on the untrimmed crape myrtle were shrunk intensively, except for retaining 20 cm to 30 cm at the base of several thick branches, and all the other branches were cut off, so as to draw more sturdy shoots in the coming year and lay a good foundation for its more flowering.
Common flowers and trees on the flower bed, along the street, and in the courtyard, such as crape myrtle, hibiscus, sweet-scented osmanthus, camphor, Fatong, purple magnolia, Admiralty, plum blossom, wax plum, cherry blossom, camellia, acacia, firethorn, Haitong, begonia, etc., cut off all the irregular branches, thin branches, bore branches, disease and insect branches, and cut the long branches protruding the crown properly. In addition, the thick palm trees can be peeled off in November to do a good job in trunk cleaning, so that it shows its due ornamental effect.
4. Keep out the cold. Potted flowers and trees that are not too afraid of cold, such as Camellia, Camellia, rhododendron, Cymbidium, Cymbidium, Phyllostachys pubescens, Sequoia, Jasmine, Magnolia, Magnolia, Dai Dai, bergamot, lemon, kumquat, cinnabar root, goose palm wood, tortoise back bamboo, spring feather, fish tail sunflower, rubber tree, wealth tree, Canadian jujube, palm bamboo, etc., can be put in a plastic greenhouse, as long as the room temperature is not less than 5 ℃.
For non-cold-resistant potted flower species, such as bamboo taro, pink daiye, synthetic taro, deep feather split vine green velvet, Milan, variable leaf wood, golden vein jade bed, golden bract, Brazilian iron, red (green) gemstone, hulk, green emperor, silver queen, egg flower, rich bamboo, Phalaenopsis orchid, Cartland, magnolia, etc., should be kept indoors at room temperature not less than 10 ℃, or you can use a double-layer plastic greenhouse to protect the winter.
For those more hardy bonsai or potted plants, such as wax plum, plum blossom, begonia, Yingshanhong, pomegranate, hammer elm, crape myrtle, melon seed yellow poplar, Finch, Luo Hansong, five-needle pine, green cypress, round cypress, triangular maple, red maple, etc., can be directly buried in the leeward and sunny soil together with the flowerpot, under the condition of not less than-10 ℃, generally will not occur frost injury. In case of particularly cold weather, it can be covered with film soft grass to prevent cold.
For potted flowers or bonsai placed in greenhouses, greenhouses or bedrooms in November, in addition to ensuring certain temperature conditions, we should also do a good job of ventilation, which can be ventilated around noon to prevent plants from falling flowers, fruits and leaves due to being stuffed indoors for a long time; in addition, there should be no gas and other toxic gases indoors, otherwise it is also easy to cause fallen leaves and fruits. When ventilating, you should also be careful not to let the plant be directly attacked by the cold wind.
5. Pest control. For the flowers and trees which are prone to leaf diseases, such as grape, begonia, rose, rose, camellia, chrysanthemum and so on, collecting and burning the fallen leaves under their plants can significantly reduce the occurrence of diseases in the coming year.
Continue to whiten the trunk of the street; dry and split-dry stump bonsai can be coated with stone-sulfur mixture to prevent the deep decay of the stump xylem.
Whitefly and scale insects on potted flowers and trees placed in greenhouses or greenhouses (dai dai, bergamot, cycad, orchid, camellia, gentleman orchid, orchid) are all likely to be wiped off with a wet cloth and sprayed with pesticides such as quick culling.
For aphids on potted plants put indoors (which may occur in Magnolia, Milan, daidai and rose), tobacco water can be sprayed to control them.
For the rhododendron placed in the greenhouse, it is necessary to stop spraying Yemianbao fertilizer, otherwise coal pollution will occur easily due to poor indoor ventilation and high air humidity.
The main types of bonsai plants suitable for modeling in November are: Luo Hansong, Cuibai, round cypress, velvet cypress, Yanbai, weeping spear, June snow, plum blossom, wax petal flower, oak, Chinese wolfberry, holly, melon seed, yellow poplar, pearl yellow poplar, hammer elm, vertical silk begonia and so on.
For the bonsai pile head which has been suspended with brown rope for 1 to 2 years, when it is found that there are deep constrictions on the stem and branch, the old brown rope can be disassembled in November and the hanging adjustment of the dry branch can be carried out again.
After preliminary root cutting, stem cutting and branch cutting, new tree stumps such as hammer elm, sparrow plum, triangular plum, bayberry, pyracantha and Elaeagnus angustifolia were planted in sandy soil by the method of shallow burial and high culture, and then modeled after branch in the coming year.
After 1 to 2 years of maintenance and modeling, the stumps that have been basically formed can be replanted in November according to the modeling characteristics of stump trunks, roots and branches, equipped with fist stones and covered with moss for indoor display before and after the Spring Festival.
Tall plum piles, Luo Hansong, green peaches, crape myrtle, cypress, tapestry, etc., can be planted in pots in November to strengthen water management and can be used for display in squares, parks and auditoriums in the coming spring.
Flower planting Handbook (December)
Weather characteristics in December: winter has entered in most parts of our country this month, and the weather is getting colder. The snowfall in China has increased from north to south, the temperature in Jianghuai and Jiangnan has dropped to below zero one after another, and the frost is frequent. The maintenance of flowers and trees this month should pay attention to three aspects: first, to do a good job in the heat preservation and anti-freezing of flowers and trees in greenhouses, greenhouses and rooms, and second, to do a good job in pruning and cleaning flowers and trees in the open field and fertilizing the fields. The third is to do a good job in the preparation of compost organic fertilizer and preparation of cultivated soil.
I. Flower reproduction
1. Sow seeds. The flower species that can be sown in the greenhouse in December are: big rock tree, asparagus, gentleman orchid, bulbous begonia, cyclamen, winter coral, African chrysanthemum and so on; the flowers and trees that can be sown outdoors or sand hide are: rose (such as Elizabeth), celadon, rich seeds, holly, fire thorns, palms, privet, camphor, lobular privet, disease-free son, heather, wood heather and so on.
two。 Cuttings. The woody ornamental flowers and trees that can be cut in the open field in December are plum blossom (mainly palace powder, green calyx, etc.), rose (mainly Elizabeth, abundant rose, miniature rose, etc.). Red leaf plum, wax plum (with heel cutting), Spiraea, yellow poplar and so on. Among them, yellow soil should be used for cutting plum blossom and red leaf plum, mixed substrate of rice chaff ash and fine sand 2 ∶ 1 should be used for rose cutting, and general sandy soil should be used for other kinds of cutting, which can be covered with plastic film to keep heat and moisture.
In the greenhouse, African violets can be propagated in leaves; combined with pruning, mulberry, geranium, lotus, epiphyllum, gemstone, stone lotus, purslane, rooting, longevity flowers, golden bracts, shrimp flowers, four seasons begonia, bamboo begonia, Rieger begonia, pearl orchid, jasmine, Longtuzhu, five-colored plum, goose palm wood, Ruixiang, green apple, Zhu Jiao and so on. Using cold room seedbed, gardenia, Jinxin (Phnom Penh) boxwood, ten meritorious services, hypericum, Admiralty, Yingchun, Luohansong, Luohanbai, June snow, firethorn, silver bud willow, three branches and so on can be propagated by cutting. In addition, branches such as Lingxiao, cloves and grapes can be cut for sand storage and cut again next spring.
3. Grafting. Fine varieties of plum blossom, such as bone red and cinnabar, can use the seedlings of apricot, fruit plum and peach sown in the same year in December to dig up the rootstocks and then split or cut them, then plant them on the seedling bed according to a certain row spacing, bury the soil above the grafting site, or even cover most of the grafted ear, pay attention not to infiltrate into the joint when watering, cover the plastic film to keep warm and wet, and then remove the covered plastic film after the scion sprouts in spring. Use the excavated wild rose plant to bud the rose of the superior variety, or use the robust branch segment of the Elizabeth rose variety (10 to 12 cm long) to cut or split the scion of the superior variety at the top, and then sow the grafted Elizabeth ear segment into a loose seedbed. The grafting part can be buried in the sandy soil, do not infiltrate into the interface when watering, cover the plastic film to keep moisture and heat preservation, remove the covered plastic film after the scion sprouts in the next spring, and then cut the binding belt of the joint with a blade after it is completely alive. In addition, it can also be bagged indoors to moisturize the abdomen and connect the red maple.
4. Press the strip. The feasible species of flowers and trees for strip propagation in December are: Luohansong, plum blossoms, camellias, sweet-scented osmanthus, Michelia, pedicel begonia, purple magnolia, snowballs, brocade flowers, gardenia, Yingchun, Admiralty, eight immortal flowers, hemp leaf hydrangea, Qionghua, snow spray, pomegranate and so on.
5. Ramet. The herbaceous flower species that can be propagated in December are: onion orchid, Ophiopogon japonicus, auspicious grass, hairpin, purple calyx, safflower grass, one-leaf orchid, Jian orchid, spring orchid, cymbidium, kidney fern, shoot stem, iris, big leaf Ophiopogon japonicus, along the steps, evergreen, rooting, Guangdong evergreen. The offspring at the base of the ramet cut from the large colored leaf pineapple must be small plants that have grown on the mother plant for three or four months, otherwise the color bands of the cut offspring are easy to disappear, which should be paid special attention.
The species of woody ornamental plants that can be propagated in December are: Phyllostachys pubescens, Hypericum, Ten Gonglao, Begonia, Brown Bamboo, Safflower Spiraea, Golden Finch, Golden Bell, Yingchun, Jasmine, Jasmine, Magnolia, Gardenia, sisal, Phoenix tail Bamboo, Phyllostachys pubescens and so on.
1. Gather seeds. The grass flower seeds that can be harvested in December are generally the species of grass flowers transferred in the greenhouse or cold room, such as a string of red, thousand-day red, marigold, malachite, cyclamen, gentleman orchid and so on. The seeds of Cymbidium should be sown as they are picked.
The main woody ornamental plants that can collect seeds in December are: rose, wisteria, privet, lobular privet, pyracantha, rich seeds, holly, camphor, and heather. After treatment, these seeds are basically required to sprout in sand and can not be sown until the seeds are white in the coming year. Under dry storage, it is easy to lose vitality, resulting in the failure of sowing and breeding in the coming year.
two。 Transplanting and planting. The herbaceous flowers that can be planted in flower beds and flower beds in December are: carnation, kale, pansy, goldfish grass, calendula, daisies and so on. Some grass flowers can also be put in the greenhouse after potting, such as daisies, calendula, goldfish grass, kale, carnation, pansy and so on, which can be used for street display next spring.
In December, most deciduous greening trees and shrubs can be transplant, such as hibiscus, pomegranate, bauhinia, begonia, wax plum, plum blossom, white magnolia, purple magnolia, disease-free son, Luan tree, acacia tree, seven-leaf tree, red leaf plum, cherry blossom, papaya, two Arbor magnolia, crape myrtle, wisteria, Lingxiao, Linden, Liriodendron, red maple, blue peach, Robinia pseudoacacia, etc. On the other hand, the transplanting of evergreen trees and shrubs should be more cautious. the evergreen species that can be transplanted in winter are: privet, sweet-scented osmanthus, palm, Magnolia, camphor, rhododendron, holly and so on. When transplanting, we should first cut the strength of the main shoots and branches and delete most of the leaves. At the same time, we also need to bring large soil balls, the trunk is bound with grass rope to cover the plastic film, the trunk and big branches are cut to seal wax or film, so as to reduce water transpiration. After transplanting, we should often spray water on the leaves and tree trunks in order to ensure their normal survival.
The stumps and flowers that can be put on the pot in December are: plum blossom, wax plum pile, camellia, tea plum, pedicel begonia, vertical silk begonia. It is expected to blossom during the Spring Festival by putting it in the greenhouse and promoting the flowering treatment.
In December, potted hyacinths, tulips and daffodils continue to be put in the shed to promote flowering, which can promote their flowering before and after the Spring Festival.
1. Keep out the cold. In a simple plastic greenhouse with a temperature of no less than 0 ℃, the following ornamental plants can be placed without freezing damage, such as Penglai pine, Tianmeng, one-leaf orchid, star anise plate, coral of golden peach leaves, sunflower, kidney fern, palm bamboo, Phyllostachys pubescens, Michelia, rich seeds, fire thorns, camellias, spring orchids, cymbidium, Phoenix tail bamboo, Phyllostachys pubescens, cycads, etc.
Ornamental plant species with an overwintering temperature of not less than 5 ℃, such as southern fir, goose palm wood, rubber tree, jasmine, brandy, pearl orchid, pocket coconut, calla lily, spring feather, tortoise back bamboo, Jianlan, Mulan, Belgian rhododendron, triangular flower, cyclamen, primrose, five-colored plum, kumquat, daidai, lemon, loose-tailed anemone, geranium, mulberry, Buddha belly bamboo, etc., can overwinter in a double-layer plastic greenhouse. For the species requiring a winter temperature of not less than 10 ℃, such as variable leaf wood, taro, pepper grass, bamboo taro, rich bamboo, fishtail sunflower, Brazilian iron, rich tree, reticulate grass, pineapple, pink leaf, poinsettia, Cymbidium, Longtuzhu, golden bract, Milan, Phalaenopsis, Cartland, Magnolia, South American iron tree, red (green) gemstone, Oncidium, tiger orchid, etc., in a double-layer greenhouse with good sealing performance. It is also necessary to heat it up properly. in the particularly cold period, from 4: 00 p.m. to 9: 00 the next day, put a grass curtain on the roof of the greenhouse, and then remove it until the temperature gets warmer.
For those more hardy potted and bonsai plant species, such as wax plum, plum blossom, begonia, Yingshanhong, pomegranate, hammer elm, sparrow plum, oak, crape myrtle, wisteria, yellow poplar, Luohansong, triangular maple, Cuibai, garden cypress, red cypress, bayberry, Chinese wolfberry, white wax, etc., generally will not be frozen when not less than-10 ℃; in particularly cold weather, cover with plastic film or soft grass to prevent cold.
[page] whether the bonsai, potted flowers, foliage and fruit plants are placed in the greenhouse, greenhouse or in the living room, in addition to maintaining the appropriate indoor temperature, we should also pay attention to ventilation. The doors and windows can be opened around noon with the highest temperature of the day to prevent the occurrence of fallen leaves, flowers and fruits. In the ventilation, we must also pay attention not to let the cold air directly attack the plant, so as to avoid adverse reactions.
two。 Water it. For most of the potted flowers and bonsai placed in the greenhouse, greenhouse and bedroom, the degree is to keep the basin soil moist. If the temperature is too low and watered too much, it is easy to cause rotting roots. When the temperature rises, the amount of water can be increased and proper foliar spray can be given.
For those potted flowers that blossom before and after the Spring Festival, such as camellia, tea plum, Belgian rhododendron, plum blossom, wax plum, melon chrysanthemum, primrose, longevity flower, hyacinth, European daffodil, etc., ornamental fruits such as daidai, lemon, bergamot, tangerine, golden bean, winter coral, rich seeds, Phyllostachys pubescens, etc., should not only keep the potted soil moist, but also spray the leaves to facilitate the expansion of flower buds. It can also increase the freshness of flowers and fruits.
For most foliage plants in the shelving room, we should not only keep the basin soil moist, but also spray water on the foliage surface, and always keep the foliage surface clean; for those foliage plant species that are not very cold-resistant, such as Fendai leaf, fruit taro, bamboo taro, leaf-changing wood, silver queen, etc., when the room temperature is close to the minimum temperature they can bear, special attention should be paid to controlling the amount of water to ensure that they can survive the winter safely.
The watering time in December should be 3 to 4 hours before and after noon, and the water temperature should be basically consistent with the air temperature and soil temperature, so as to avoid adverse reactions caused by low water temperature.
Newly transplanted flowers and trees outdoors should be checked frequently and replenished in time; for transplanted evergreen trees, foliar spray can be given around noon to prevent leaves from drying and falling off.
3. Fertilize. For most of the potted flowers and trees, foliage plants and bonsai placed in the general greenhouse, fertilizer should be stopped, otherwise it is easy to cause the plant to rot and die.
Most of the green trees and flowers planted on the ground Such as Begonia, Magnolia, Magnolia, Magnol Cryptomeria fortunei, cedar, cypress, Robinia pseudoacacia, elm leaf plum, Yu Li, white silk plum, heather, bauhinia, hibiscus, etc. While ploughing the garden field in December, fertilizers such as cake fertilizer, pig and cow manure, pond mud and septic tank residue can be applied to the periphery of the plant root system, so as to lay a good material foundation for next year's growth and flowering.
For potted flower species placed in the room from 10 ℃ to 15 ℃, such as camellia, tea plum, rhododendron, plum blossom, wax plum, golden bract, shrimp flower, pineapple, Ruixiang, melon leaf chrysanthemum, primrose, cyclamen, pedicel begonia, hyacinth, gentleman orchid, tulip, freesia, etc., 1.2% potassium dihydrogen phosphate can be applied to promote the pregnant bud and flowering of the plant.
4. Trim. The hedgerows, green walls and ball shapes that have not been pruned in November are trimmed, such as privet, lobular privet, Fa Qing, big leaf boxwood, Shu juniper, four seasons cinnamon, spinulosa heather, etc.; balls such as gooseberry, bayberry, heather, yellow poplar, Haitong, Admiralty, pyracantha, dragon cypress, juniper, etc., can be fertilized while completing pruning.
The ground-planted flowers and trees that have not been pruned in November, such as rose, crape myrtle, palm, red leaf plum, heather, Fatong, plum blossom, wax plum and so on, can be pruned and fertilized around the root system after pruning.
For bonsai plant species dominated by shearing, such as hammer elm, sparrow plum, medlar bone, Fujian tea, maple, oak, white wax, fire thorn, June snow, Luohansong, cypress, cypress, begonia, papaya, etc., continue to prune in December to lay a good skeleton for next year's growth; plants that have not changed pots for many years can be combined with pruning to change pots.
5. Pest control. For flowers and trees that are prone to diseases and insect pests in the leaves of grape, begonia, rose, rose, camellia, crape myrtle, etc., the litter under their plants will be collected and burned, which can reduce the occurrence of diseases next year. At the same time, spray stone sulfur mixture for sterilization and disinfection.
For powdery mildew of potted melon-leaf chrysanthemum and Botrytis cinerea of primroses, the former was controlled by triadimefon or thiophanate-methyl in time, and the latter was controlled by thiophanate-methyl.
For the species of scale insects that are easy to appear in flowers and trees in the greenhouse, such as hadai, bergamot, cycad, camellia, orchid, etc., you can first wipe them with a dishcloth, and then use pesticides such as quick culling.
When there is poor ventilation, aphids often appear on potted plants, such as Magnolia, Milan, daidai, rose, Fujian tea, etc., can be controlled by tobacco water.
On the trunk and big branches of flowers and trees such as Haitong, sweet-scented osmanthus, Fatong, camellia, lobular privet, pyracantha, oleander, begonia, Magnolia, bauhinia, gardenia, cedar, heather, crape myrtle, wax plum, etc., there are many kinds of scale insects that often appear on the trunk and big branches of flowers and trees, such as horned wax scale, Japanese tortoise wax scale, red wax scale, shield scale, sagittal scale, pink scale, velvet scale, etc., at this time, spray and kill with high concentration of pesticides such as quinathulfan, quinathulene, buprofezin and other pesticides. Drug damage is rarely caused.
6. Compost. In order to meet the needs of raising seedlings and preparing culture soil next year, rapeseed cake, bean cake and tea seed cake can be poured into water tank and pool for sealed soaking fermentation.
Dry withered grass, fallen leaves, shrubs, branches, etc., are piled up in layers with the garden soil, ignited and burned to form burning soil, which is a good covering soil for sowing and raising seedlings next year.
Compost, pond mud, chicken droppings and pigeon manure were mixed with garden soil and sealed fermentation, which can be used for topdressing seedlings and preparing culture soil in the coming year.
7. Prepare culture soil. Make use of your winter free time to find an open space or pile up as much culture soil as possible in the shade of trees in case you need to change pots and plant flowers next spring. Generally, there are 4 parts of garden soil, 2 parts of rotten leaf soil (or 2 parts of alpine humus soil), 1 part of fine sand, 1 part of piled sawdust, tobacco dust or bran ash, plus about 5% retted cake fertilizer and 2% to 3% compound fertilizer. Among them, garden soil and rotten leaf soil should be screened, gravel, tree roots and other sundries should be sifted, fully mixed, covered with plastic film, and can also be stacked indoors after 3 to 4 months. It can be used for changing pots or potting grass flowers.
8. Turn over the ground and freeze. For the garden used for sowing, cutting and planting seedlings next year, ploughing can be carried out in December; the garden for sowing and planting seedlings can be applied cake fertilizer, barnyard manure, pond mud and so on before replanting; temporarily do not make a bed, after freezing over the winter, to make a bed in the early spring of next year, it can greatly reduce the cost of seedling management, but also reduce the occurrence of diseases and insect pests.
The ornamental plants suitable for bonsai modeling in December are: Luohan pine, Luohanbai, garden cypress, cypress, velvet cypress, Platycladus orientalis, Sabina vulgaris, black pine, five-needle pine, red pine, bayberry, wolfbone, holly, weeping spear, ginkgo, June snow, broom elm, finch, triangular maple, wax petal flower, Tamarix, pedicel begonia, weeping silk begonia, papaya begonia, melon seed yellow poplar, pearl yellow poplar, wisteria, purple myrtle, banyan, banyan, Fujian tea, white wax, oak and so on.
For bonsai plants fixed with brown wire (rope) or wire, if it has been fixed for one year, or obvious constriction marks are found on the stem or branch, the original ligature should be removed and the wire or brown rope should be used for hanging traction.
For plum piles, Luohansong, begonia, ginkgo, cypress, crape myrtle, etc., after some necessary pruning and plastic surgery, choose a good pot for planting and strengthen management, so that they can be used in public places or rooms for display in the coming year.
In winter, we must carefully manage some shallow landscape bonsai and tree stump bonsai: first, to prevent the roots of plants from frostbite in the basin soil; second, to prevent the disintegration of artificial cemented rocks caused by freezing; and third, to prevent plants planted on rockery from freezing or drying to death. It can be placed in an ice-free place and watered regularly so that it can survive the winter safely.

6. Gather seeds. In January, if there are mature asparagus and magnolia seeds in the greenhouse, they can be picked and sown, mature winter coral seeds, and can also be sown indoors at this time. The seeds of Phyllostachys pubescens, Firethorn, holly and rich seeds can be picked in January, and the seeds can be sown after the seeds are exposed to white.
In January, the seeds stored in sand should be checked frequently, including magnolia, Michelia, heather, holly, etc., to see if there is mildew in the seeds. If mildew occurs, the seeds must be poured out and re-scrubbed, and clean fine sand must be replaced for storage; if the seeds are found to be dry, spray water should be given in time. If it is found that the seed has been white or the radicle has stretched out, it must be sowed immediately and covered with plastic film or rice straw, pine needles and other heat preservation and moisturizing.
two。 Transplanting and planting
In January, grass flowers that can be transplanted and planted in less cold areas are: carnation, kale, calendula, daisies, etc.; in relatively cold areas, after sowing seedlings such as carnation, kale, goldfish grass, pansy and primroses, they can be placed in a simple plastic greenhouse and used as a display of street flower beds, green spaces and flower borders when the air is warmed up in spring.
In January, most deciduous shrubs and green trees can be transplanted and planted Such as hibiscus, pomegranate, bauhinia, begonia, ginkgo, maple, maple, wax plum, plum blossom, white magnolia, red leaf plum, cherry blossom, papaya, two Qiao magnolia, crape myrtle, wisteria, Lingxiao, Linden, Liriodendron, green peach, Chinese tallow, red Spiraea, three branches, rose, Robinia pseudoacacia, dragon claw locust and so on. Evergreen tree species, especially Cinnamomum camphora and Fa Qing, should be transplanted in advance to December or postponed to February this month except for special circumstances. Of course, in places of shelter, intensity shearing is carried out after transplanting, and cold protection and watering management are strengthened after transplanting.
In January, despite the cold weather, the collection of wild tree stumps in the south of the Yangtze River did not affect the collection of wild tree stumps in the process of afforestation and land preparation, mainly deciduous tree stumps, such as Ulmus pumila, Sparrow Plum, triangular Maple, Yingshanhong, crape myrtle, Acer sinensis, wisteria, Wintersweet, Wild Plum, Elaeagnus angustifolia, Weisheng Spear, etc. For evergreen stumps, such as Phyllostachys pubescens, Maoer thorn, medlar, holly, oak, etc., strength shearing must be done and most of the leaves must be deleted. Both deciduous stumps and evergreen stumps should be cultivated by shallow burying and high cultivation, and covered with grass curtain to prevent freezing.
three。 Guard against cold
This month's cold prevention and heat preservation work is the top priority in the management work, a little negligence will bring serious losses to bonsai and bonsai overwintering. According to the lower limit of the lowest temperature that can be tolerated by different flower species, a special environment for them to survive the winter should be created, either in a greenhouse, in a greenhouse, at home, or buried in open soil. In a simple plastic greenhouse of no less than 0 ℃, ornamental plant species that can withstand a low temperature of about 0 ℃ can be placed, such as Penglai pine, Tianmeng, one-leaf orchid, star anise, sunflower, kidney fern, brown bamboo, southern bamboo, peach leaf coral, Michelia, Chunlan, magnolia, rich seeds, Daphne, cycad, calamus, Phoenix tail bamboo, phenanthrene bamboo, white bamboo and so on. In a double-layer plastic greenhouse of not less than 5 ℃, you can put ornamental plant species that can withstand a low temperature of about 5 ℃, such as southern fir, rubber tree, jasmine, pearl orchid, magnolia, pocket coconut, bottle orchid, calla lily, spring feather, tortoise back bamboo, kumquat, daidai, lemon, sunflower, camellia, tea plum, Jianlan, orchid, epiphyllum, Ling Arrow lotus, big Buddha belly bamboo, Belgian rhododendron, triangular plum, five-colored plum and so on. Flower species that can withstand low temperatures of about 10 ℃ can be placed in double-layer plastic greenhouses or greenhouses with auxiliary heating equipment. Such as variable leaf wood, flower leaf taro, taro, pineapple, pepper grass, colored leaf grass, rich bamboo, fish tail sunflower, Brazilian iron, wealth tree, reticulate grass, red (green) gemstone, hulk, green emperor, silver queen, Milan, Cymbidium, Phalaenopsis, Cartland, Oncidium, Magnolia, gold tree, South American iron tree, desert rose, pink, poinsettia, golden bract, coral flower, etc., during the very cold period. From 4: 00 p.m. to 9: 00 p.m., it is appropriate to cover the grass curtain on the roof of the greenhouse, and the grass curtain can not be stopped until the temperature turns warm. In very cold days, it is necessary to strengthen the inspection of heating facilities and personnel on duty, especially from 5 o'clock to 6 o'clock in the morning, do not cut off the fire and power, otherwise it is easy to cause freezing damage to the plants. For those more hardy species of potted flowers and bonsai, such as Chimonanthus praecox, plum blossom, begonia, Yingshanhong, pomegranate, elm, sparrow, oak, crape myrtle, wisteria, yellow poplar, Luohansong, triangular maple, cypress, round cypress, summer cypress, Platycladus orientalis, small bayberry, Chinese wolfberry, holly, opposite section white wax, etc., can be buried together with flowerpots, when not less than-10 ℃, generally will not occur frost injury In particularly cold weather, cover with plastic film or soft grass to keep warm.
It is worth noting that whether it is placed in a greenhouse, in a greenhouse, or at home for potted flowers or bonsai, including ornamental fruits and foliage plants, in addition to maintaining the appropriate temperature, we should also do a good job of ventilation and ventilation. Doors and windows can be opened around noon when the temperature is highest in the day to prevent falling flowers, leaves and fruits. When giving ventilation, we must also try our best to avoid cold air blowing directly on the plant.
In January, special attention should be paid to the inspection of greenhouses and greenhouses in the process of air-conditioning going south, and glass breakage and film tearing were found, and leakage plugging should be carried out in time to avoid freezing the potted flowers. In the greenhouse to provide coal, gas, oil heating, should also be carefully checked, there should be no air leakage, smoke leakage into the greenhouse or greenhouse, in order to prevent falling flowers, leaves and fruits caused by smoke damage.
In order to promote peony blossom during the Spring Festival, potted peony can be placed in a greenhouse, heated to 18 ℃ to 25 ℃ during the day, and kept at about 10 ℃ at night, adding 4 to 5 hours of light every day (incandescent light). It is expected to blossom before and after the Spring Festival. Potted plum blossoms, wax plums, camellias, camellias, camelli Potted hyacinths, tulips, daffodils and freesia, which have been placed in the greenhouse in December, will strengthen the management of water and fertilizer and are expected to be used for decoration and display during the Spring Festival. [page]
four。 Watering
In the watering management of potted flowers in January, the most important thing is to pay attention to the temperature of watering and spraying water, that is, to keep the water temperature roughly consistent with the soil temperature. if the gap between them is too large, it is easy to cause adverse reactions of potted plants. even make the plant deciduous, rotten root or death. Watering time is best arranged for 2 to 3 hours before and after noon. Secondly, according to different plant species, determine the number, times and methods of watering. For most of the potted flowers and bonsai placed in the greenhouse, greenhouse and bedroom, it is appropriate to keep the potted soil moist, and those with low temperature should reduce watering correspondingly. When the temperature rises, the amount of water can be increased and foliar spray can be given. For most foliage plants, we should not only keep the basin soil moist, but also pay attention to spraying water on the leaves, and always keep the leaves of the plants clean. For the species of foliage plants that are not very cold-resistant, such as Fendai leaves, taro, taro, variable leaf trees, etc., when the air temperature is close to the lowest temperature that the plant can bear, the amount of water should be specially controlled. For those species of potted flowers that will blossom before and after the Spring Festival, such as camellia, tea plum, Belgian rhododendron, poinsettia, melon and leaf chrysanthemum, wax plum, plum blossom, primrose, hyacinth, longevity flower, calendula, etc., and ornamental fruits such as firethorn, daidai, bergamot, lemon, rich seed, kumquat, golden bean, winter coral, not only to keep the potted soil moist, but also to spray water on the plant to facilitate the expansion of flower buds. It can also increase the bright color of the fruit.
Although potted flowers do not need much water in January, inspection should be strengthened to prevent water shortage of potted flowers placed in remote parts, and timely supplementary watering of dried plants in pot soil can reduce the death of overwintering plants.
For newly planted green trees and flowering shrubs, they should be checked frequently and watered in time, especially for those evergreen ornamental plants after transplanting, they should also be sprayed properly around noon to prevent the leaves from shrinking and falling off due to excessive air dryness.
five。 Fertilizer application
For most of the green trees and flowering shrubs planted on the ground Such as Begonia, Magnolia, maple, gardenia, seven-leaf tree, camphor, Linden, crape myrtle, Lingxiao, sweet-scented osmanthus, wax plum, plum, cherry, cherry-free, acacia, Luan, palm, Schima superba, runnan, purple tree, camptotheca, peony, golden bell, yellow poplar, grape, coral tree, rose, hydrangea, red leaf plum, Yu Li, elm leaf plum, horse Liriodendron wood, Shu Shu, Prunus mume, Muxiang, du Ying, Golden Salix, hanging Elm, Cryptomeria fortunei, Cryptomeria fortunei, Cedar, Robinia pseudoacacia, Robinia pseudoacacia, White Silk Plum, Hibiscus, clove, crape myrtle, Photinia, Phyllostachys pubescens, Pomegranate, Loquat, etc. If the fertilization task is not completed in December, cake fertilizer, barnyard manure, pond mud and septic tank cleaning materials can be buried on the periphery of the tree root system while the soil is turned over, so as to lay a good material foundation for the growth and flowering of spring.
Potted flowers placed in a greenhouse of about 10 ℃ to 15 ℃, such as Belgian rhododendron, shrimp flower, golden bract, Ruixiang, melon and leaf chrysanthemum, primrose, cyclamen, red mouth daffodil, tapered begonia, hyacinth, tulip, colorful pineapple, orchid, orchid, crab claw orchid, etc., can continue to apply low concentration of potassium dihydrogen phosphate solution, in order to facilitate plant growth and bud blooming.
For most of the potted plants, foliage plants and bonsai put in the greenhouse, as the plants are dormant in winter, fertilizer should be stopped, otherwise it is easy to cause rotting roots of the plants to die.
six。 Pruning
Continue pruning hedges, green walls and balls that have not been pruned in December, and continue pruning flowers and shrubs that have not been pruned in December, such as rose, crape myrtle, wood incense, Lingxiao, wisteria, abundant rose, camphor, Fatong, Chinese tallow, heather, pomegranate, red leaf plum, papaya, wax plum, plum blossom, palm, grape, etc. After pruning, base fertilizer is applied to the periphery of the root system to meet the needs of its spring growth.
According to the original composition requirements, bonsai plant species dominated by shearing and supplemented by pruning, such as hammer elm, sparrow plum, triangular plum, Fujian tea, oak, white wax, bayberry, Elaeagnus angustifolia, pyracantha, June snow, juniper, etc., can continue to be adjusted and trimmed according to personal aesthetic taste to lay a good foundation for the growth and formation of spring. At the same time of pruning, plants that have not changed pots for many years can be changed.
seven。 Pest control
The trunk or big branches such as crabapple, plum blossom, elm leaf, papaya, loquat, blue peach, cherry blossom, red leaf plum, etc., can be sawed off by red-necked longicorn beetles, and the sawed stems and branches can be burned.
Cleaning up the leaves under the trees such as rose, rose, grape, crape myrtle and so on, and burning them centrally after collection can reduce the occurrence of leaf diseases in the coming year.
On the trunk and branches of Haitong, Fatong, privet, firethorn, persimmon, gardenia, plum blossom, red wax scale, cotton blowing scale, shield scale, sagittal scale, pink scale, line scale, etc., spraying and killing with high concentration of quick culling, quinathion, parathion, stone sulfur mixture can effectively inhibit the occurrence of scale insects in that year.
Powdery mildew on melon-leaf chrysanthemum in greenhouse and Botrytis cinerea on primrose leaves can be controlled with thiophanate-methyl to prevent it from spreading to other plants.
To carry out comprehensive control of scale insects and coal pollution on daidai, bergamot, kumquat and other plants in the greenhouse, first wipe off the coal spots on the leaves and the insects attached to the dry branches with a wet cloth, and then spray pesticides such as dimethoate.
Botrytis cinerea on cyclamen plants in the greenhouse can be sprayed 1000 to 1500 times with 50% prohydantoin (mainly composed of isocarbamide) wettable powder.
eight。 Compost fertilizer
Pour rapeseed cake, bean cake and tea seed cake into a pool or tank for soaking and fermentation, so as to provide pot flowers for pouring during the growing season; layer-by-layer accumulation of withered grass, branches, fallen leaves, etc., with garden soil, ignition and burning, self-made burning soil, which can be used as covering soil for sowing and breeding in spring; mixing barnyard manure, pond manure, smoke powder, chicken feces and pigeon dung with garden soil for composting and fermentation can be used as fertilizer for preparing culture soil.
nine。 Ploughing and freezing
The nursery land that has not been reclaimed in December can be ploughed in the first ten days of January. while ploughing the garden, cake fertilizer, compound fertilizer and soil fertilizer are applied, and after freezing over the winter, ditches are made to make beds in early spring for sowing and planting seedlings.
Because January is particularly cold, the plant species suitable for styling must be those with soft branches, good toughness, ginkgo, melon seeds, yellow poplar, velvet cypress, cypress in June, snow in June, cypress, cypress, five-needle pine, yellow pine, black pine, bayberry, canary, wax petal, weeping spear, banyan, wisteria and so on. After modeling, it is best to put it indoors or in a simple plastic greenhouse, and then move to the outside after the air is warm in spring, which is conducive to the healing of damaged parts.
For the plants shaped with brown rope or wire 1 or 2 years ago, if obvious constriction is found in the binding site, the original ligature should be removed and flat traction should be carried out again.
In January, the management of some shallow pot tree stump bonsai, shallow basin landscape bonsai and small, miniature bonsai should be strictly strengthened. Small and miniature bonsai should be buried on the indoor sand bed; tree stump bonsai should prevent the basin soil from freezing, injure the hairy roots of the plant, cause the disintegration of man-made cemented rocks, and prevent the plants planted on the pebbles from withering after being frozen, it is appropriate to put them in an ice-free place and water and spray them regularly to ensure that they can survive the winter safely.

Knowledge of hydroponic Flower | Ten questions on hydroponic Flower Technology
1. What kind of flowers are suitable for hydroponic culture? What are its advantages?
Answer: theoretically, any flower can be hydroponically cultured, but different kinds of flowers have different requirements for the environment. For example, some varieties that need to control water to promote flowers may have an impact on flowering under hydroponic conditions, and some plant lines are sensitive to hypoxia. It is necessary to pump air into the nutrient solution regularly to replenish oxygen. At the same time, different kinds of flowers have different nutritional requirements, so it is necessary to adopt the appropriate formula of nutrient solution. Therefore, flowers and plants can not be hydroponically cultured until they are properly domesticated and adapted. There are many plants suitable for hydroponic culture, including money tree, rich tree, bean green, sun god, bamboo taro, cherub, Marianne, mountain and kelp, golden cactus, golden orchid, tiger tail orchid and so on. Hydroponic flowers can be a long bath without watering and fertilization, the same leaves, clean and hygienic, beautiful and elegant, is the first choice for home beautification and greening.
2. What substances are contained in the nutrient solution of hydroponic flowers?
A: hydroponic nutrient solution contains all the essential nutrients needed for flower growth, including nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, zinc, copper, boron, molybdenum, atmosphere and so on. It is a colorless, tasteless, non-toxic product, please rest assured to use.
3. Why do hydroponic flowers use two concentrates?
Answer: the reason why the concentrated nutrient solution of hydroponic flowers is divided into two parts is mainly because it is considered that when the concentration of calcium, magnesium, iron, zinc, copper and other metal nutrient elements in the nutrient solution is too high, it will precipitate each other and make the nutrition invalid. therefore, in order to ensure adequate and balanced nutrient supply, these non-toxic compounds cannot be mixed together in the concentrated nutrient solution. Therefore, at present, the hydroponic nutrient solution sold on the market is only one kind, and the nutrients are often unbalanced.
4. Is the nutrient solution in the hydroponic flower container as much as possible?
A: no. The depth of nutrient solution in the container should be determined according to the growth of flower roots, not too much. In general, when the root system is relatively developed, part of the root system should be exposed in the air above the liquid surface so that the root system can absorb part of the oxygen from the air, which is very good for the healthy growth of the root system. Do not add too much nutrient solution to the container, but not too little, if it is too little, you need to replenish the nutrient solution frequently, resulting in inconvenient management. It is usually enough to maintain a nutrient layer about 5-10 cm deep.
5. Should hydroponic flowers bask in the sun?
A: it depends on the light demand characteristics of the flowers you grow. If it is a shady type, it is not suitable to let the sun shine directly, but because the hydroponic flowers decorated in the home are usually in a poor light environment, even shady flowers need to be placed regularly on the balcony with slightly stronger light. In general, one day a week when the delivery on the balcony on it.
6. Do hydroponic flowers need a nutrient solution for each kind of flower?
A: no. There are many varieties of hydroponic flowers, but not every kind of flower needs a corresponding nutrient solution, as long as according to different categories to choose different nutrient solution, of course, you can also use a general-purpose nutrient solution. At present, the soilless cultivation Technology Laboratory of South China Agricultural University has developed five types of nutrient solutions: general type, foliage type, inner plant type, orchid type and flower type.
7. Can't flowers cultivated in soil be directly converted to hydroponic culture?
A: the transition from soil cultivation to hydroponic culture must go through a series of treatments. First of all, the soil-cultured flowers are taken out to wash the roots, and then soaked in the hydroponic root treatment solution for about 20 minutes before they can be put into hydroponic containers for hydroponic culture.
8. Does co-culture of flower fish need to be fed?
A: there is no need for feeding. Because most of the fish tails raised by flower fish are small, these fish only need to absorb plankton and root exudates from the nutrient solution to meet their needs. if fed, it is easy to cause the fish to be overfed and died. at the same time, the addition of feed is also easy to cause turbidity of the nutrient solution, and the content of dissolved oxygen in the nutrient solution decreases, affecting the growth of flowers and fish.
9. Replenish or replace nutrient solution when hydroponic flowers are cultivated?
Answer: this depends on the rate of water consumption of plants. If the weather is dry and the plants are larger, it is generally necessary to replenish the nutrient solution after 15-20 days, and the right amount of nutrient solution can be added. Do not replenish the nutrient solution too much, you only need to add about the depth of the container 1 to 3-1 to 2.
10. How long is the period of validity of concentrated nutrient solution for hydroponic flowers? What should you pay attention to when storing?
Answer: the period of validity of hydroponic flower concentrate is almost unlimited, but generally do not use more than 5 years of storage, concentrated nutrient solution storage is to avoid light as far as possible, do not put it in a place accessible to children. Discussion on the experience of hydroponic Flower Culture in Family
As an environment-friendly way of growing flowers, compared with traditional soil-cultured flowers, hydroponic flowers have the following characteristics: ① uses water instead of soil, odorless and tasteless, clean and hygienic. ② does not need to change the pot and loosen the soil, so it can reduce the labor of growing flowers. ③ is light in weight and can be moved anytime and anywhere. The material selection of ④ is flexible and can be matched reasonably according to indoor furnishings. There are few harmful microorganisms in ⑤ water and the seedling rate is high. The seedling rate can be stable at more than 80%.
1. Flower varieties suitable for hydroponic culture have been proved by many years' practice that foliage plants are the first choice for family hydroponic flowers, such as Guangdong evergreen, evergreen, tortoise back bamboo, sea taro, green apple, rich bamboo, asparagus, aloe, duck toe grass, hanging bamboo plum, colored leaf grass, Brazilian wood, pocket coconut, mulberry, hanging golden bell and so on. In addition, a string of red, rhododendron, camellia, cyclamen, Zhu Dinghong, calla, tiger prickly plum, longevity flowers, hyacinth, and so on, this kind of flowering plants have a good effect of hydroponic culture. Kidney fern, marigold, petunia, red back cinnamon and other hydroponic flowers have a low survival rate.
2. Selection of hydroponic containers and mattress substrates ① containers. Any beautiful container that can hold water is fine. It is best to use transparent containers, such as beverage bottles, wine cups, teacups, vases, fish tanks, etc., with a larger mouth to facilitate gas exchange. The size, height, shape, color and texture of the container should be in harmony with the hydroponic flowers. It is best to clean and disinfect before use. ② pad substrate. The cushion substrate is often placed at the bottom of the hydroponic container, which mainly plays the role of stabilizing the plant, such as pebbles, yellow sand, perlite and so on. Small pebbles with elegant appearance and different shapes are the best. It should also be cleaned and sterilized before use.
3. The time of hydroponic culture is the most suitable for hydroponic culture in spring and autumn, but it also varies with flower species. If the indoor temperature is 15 ℃ ~ 28 ℃, foliage plants can be carried out all the year round. Flowering plants should be carried out when the first flower is budding, such as cyclamen, hyacinth, rhododendron, camellia, etc. are often hydroponically cultured in early January, so that the blooming season coincides with the Spring Festival, giving people the joy of spring flowers.
4. Acquisition and treatment of hydroponic materials ① root washing method. Select potted plants with full shape, exuberant growth and free of diseases and insect pests, remove the soil from the pot, wash the soil of the roots with water close to room temperature, and cut off the decayed and aged roots. The dense fibrous roots can be cut off about 1pm 3, but new roots should be avoided, and then soak the roots in 50% potassium permanganate solution for 30 minutes. It can not only sterilize and disinfect, but also promote the hair of new roots, and then carry out hydroponics. This method is mostly used for larger plants and flowers that are difficult to root. ② water insertion method. The sturdy and pest-free semi-lignified branches were cut and inserted in water for hydroponic culture. The cutting part is often two or three millimeters below the stem node, and the cut should be cut with a sharp knife. Scrub, disinfect and smooth with liquor in advance, and remove the lower leaves of the branches. Before rooting, it is best to choose opaque containers or wrap black plastic bags on transparent containers to facilitate cuttings to take root. This method is mostly used for flower varieties with easy rooting and fast growth.
5. ① water for hydroponic culture and exchange water. Mountain spring water is the best, its water quality is clean, no pollution, no precipitation, and contains a variety of trace elements necessary for plant growth. Cold boiled water takes second place. It is best not to use tap water, because it contains many impurities, easy to precipitate, and the chlorine in it is harmful to plant growth. If Rain Water or snow water culture can be used, it is more beneficial to the growth of flowers. ②, change the water. Due to the normal growth and metabolism of plants, after hydroponic culture for a period of time, the oxygen in the water is continuously consumed, at the same time, the root system produces mucus, the water quality is not as fresh as at the beginning, and the nutrient solution added to the water is also absorbed by the plant. too many unabsorbed elements will also do harm to flowers. Therefore, the water must be changed regularly. The change of water quality is directly related to the temperature. Spring and autumn is the flourishing period of flowers, changing water every 7 ~ 10 days, every 4 ~ 6 days in summer, and about 15 ~ 20 days in winter. Every time you change water, you should wash away the mucus from the roots and cut off the aged roots and rotten roots. The height of adding water is equal to that of the rhizosphere, too deep is easy to rot roots due to hypoxia, and too shallow is easy to affect the growth of roots due to lack of water.
6. The addition of hydroponic nutrient solution is the fertilizer of hydroponic flowers. In general, new roots can be produced after hydroponic culture for half a month. With the growth of flowers and plants, we must constantly change water and add nutrient solution. According to the need to buy different types of flower nutrition solution on the market. It must be noted that all kinds of nutrient solutions purchased by ① are raw solutions and must be diluted. The dilution ratio varies with different kinds of flowers, so you should read the instructions carefully. All kinds of special nutrient solution for ② must be special to avoid getting the wrong object. If the orchid nutrient solution is applied to the orchid flowers, the orchid will not blossom or blossom very little. Some flowers do not need nutrient solution, especially in the dormant period, directly regularly change water or add a small amount of sugar water, salt water, the effect is also good, such as green pineapple, evergreen and so on.
Control techniques of Diseases and insect pests in hydroponic Flowers
Hydroponic culture can get rid of the infection of soil diseases and insect pests, but it does not grow in the vacuum environment after strict disinfection, and it will still be damaged by environmental diseases and insect pests. Fungi, bacteria and viruses in the air can still infect the stems and leaves of hydroponic flowers, making them suffer different degrees of pathological changes. Aphids and shell insects can float indoors with the wind and fall on hydroponic flowers to suck juice. Moths lay eggs on flowers, hatch into larvae, and eat the tender leaves and stem tips of flowers. Take off the basin to wash the roots to static hydroponic flowers, will also carry fungi, bacteria, viruses, eggs, larvae, etc., if not carefully checked and cleared, it will leave hidden dangers.
Static hydroponic flowers because of the particularity of their display environment, once the occurrence of diseases and insect pests, it is not suitable to use chemical pesticides to kill insects, nor can they be sterilized with large doses of fungicides. Although these drugs can play the role of insecticidal and sterilization, they can also cause pollution to the environment.
Prevention should be given priority to the diseases and insect pests that may occur in hydroponic flowers. When choosing flowers for hydroponic culture, we should try our best to select flowers with strong plants, luxuriant growth and no diseases and insect pests. If insect pests are found in the process of cultivation, they can be caught manually or washed away with tap water. There are not many infectious diseases in hydroponic flowers, only a few leaves have brown lesions, dry necrosis, or irregular round wet lesions, which are formed by fungal or bacterial infection. After discovery, the whole diseased leaves should be removed and burned, so as not to spread. Prevention of non-infectious diseases. Non-infectious disease is not caused by pathogen infection, it is caused by unsuitable environment. Muggy high-temperature weather in summer, cold winter, dry climate, scorching sun, obstructed air environment, excessive shade, excessive concentration of nutrient solution, or can not be evenly absorbed may cause static hydroponic flower leaf tip scorch and scorch, lower leaves yellowing and falling off. Hot summer temperature is too high, due to a sharp decline in dissolved oxygen in the liquid, and prone to root rot, which is a common symptom of static hydroponics. According to the above different symptoms, find out the corresponding causes, correct them, improve the cultivation environment, and avoid the occurrence of non-infectious diseases.
How to maintain the still hydroponic flowers with disjointed and rotten roots? Due to improper management, or rotting roots due to hypoxia, or infected by fungi, bacteria and viruses, hydroponic flowers have leaf spot disease, leaves yellowing and falling off, resulting in disconnection of the lower end and loss of ornamental value. The hydroponic flowers with disjointed and rotten roots can be treated by the method of plant renewal. The branches that are still intact at the upper end of the stem node are cut off and inserted in clean water. After a period of maintenance and management, new roots can grow and become independent plants. The disjointed branches at the lower end can sprout new buds in the stem nodes as long as they do not rot, and they can be cultivated in nutrient solution at this time. Fugui bamboo, green pineapple, colorful plantain, taro, and so on, can all use this method.
Complete Handbook of Family hydroponic Flowers
There are four methods to obtain hydroponic plants: first, the flowers cultivated in organic media such as soil or inorganic substrates are removed from the pot, and the soil or inorganic matrix on the roots is removed and changed to static hydroponic culture in nutrient solution. Second, use the branches of flowers as cuttings, insert them directly into still water, and cultivate them with nutrient solution after rooting. Third, when some flowers grow, there will be walking stems (stolons), and there are small plants growing on the stems, such as orchids and pineapples, which can be removed for direct hydroponic culture. Fourth, flowers with more tiller buds, such as orchids and pineapples, can be hydroponically cultured by peeling tiller buds with roots. How to prepare hydroponic nutrient solution family hydroponic flowers (or hydroponic flowers for short) must have three basic conditions: first, select plants that are closely related to aquatic plants, that is, plants that retain aquatic genetic genes, which can be used as static hydroponic flowers. Second, select the cultivation container with no leakage and no bottom hole that matches the size and style of hydroponic flowers. Third, the use of ion balance absorption (appropriate ratio), low conductivity nutrient solution with all-element mineral nutrition necessary for the growth of flowers and plants. The recommended formula is as follows: (1) A large number of elements: 0.27 grams of calcium nitrate, 0.13 grams of potassium nitrate, 0.08 grams of potassium dihydrogen phosphate, 0.13 grams of magnesium sulfate. (2) Trace elements: disodium ethylenediamine tetraacetate 8.0 mg, ferrous sulfate 5.0 mg, manganese sulfate 1.4 mg, boric acid 2.0 mg, zinc sulfate 0.07 mg, copper sulfate 0.04 mg, sodium molybdate 0.09 mg. (3) purified water: 1 liter (1000 ml). The pH value is from 5.5 to 6.5, and the electrical conductivity EC is less than 0.5mm / cm. The selected flowers will be cultivated in utensils and injected with hydroponic nutrient solution to become a static hydroponic flower with unique charm. In the preparation of nutrient solution, it is best to use pure water, of course, drinking tap water can also be used to prepare nutrient solution. They are strictly treated, clean and hygienic, and meet the requirements of aseptic (few bacteria) cultivation. However, it must be fully noticed that there are fewer impurities and bacteria in the purified water, and there are basically no essential nutrient elements for plants, while tap water contains unstable nutrients with the change of the composition of the water source. Therefore, the composition of the nutrient solution prepared with pure water is stable and consistent, and the composition of the nutrient solution prepared with tap water is unstable. Liquid chlorine is used when disinfecting tap water. If there is too much chlorine in tap water, it is harmful to flowers and plants. A water purifier can be installed on the faucet. Release the tap water, store it in a large-caliber bucket and put it aside for a few days, stir it with a stick several times to remove chlorine. If you are in urgent need of changing water, you can add 3 to 5 grains of sodium thiosulfate (commonly known as baking soda) in 10 kg of tap water and stir evenly to achieve the effect of removing chlorine. Most foliage flowers like the slightly acidic soil environment, and their alkali tolerance can not be changed in hydroponics. The pH of the solution must be adjusted to 5.5 to 6.5 in static nutrient solution cultivation, which is beneficial to the absorption of trace elements by flowers, the physiological metabolism is not disturbed, the growth is normal and the leaves are green.
How to apply fertilizer outside the root
Static hydroponic cultivation of flowers is a cultivation method under the condition of anoxic root system, which will cause some defects to the normal development of flowers. In order to improve the quality of flowers, foliar fertilization can be used to supplement nutrient elements. During the vegetative growth period of flowers, 0.2% potassium nitrate dilution can be used to spray foliar. Should use fine hole spray pot, try not to make fertilizer liquid loss, the back of the leaf should also be sprayed, spray once a week, spray twice during the growing period, can make hydroponic flowers flourish. Flowers suitable for leaf viewing and flower appreciation at the same time, such as taro, begonia, bamboo begonia, calla, etc., can be sprayed on the leaves once a week with 0.15% potassium dihydrogen phosphate diluent during the budding period until the flowers bloom. The temperature requirement of hydroponic flowers hydroponic cultivation of flowers only changes the way of flower cultivation, does not change the growth habits of flowers, and it is impossible to change their habits. The foliage flowers and plants used in static hydroponics are mostly originated in Latin American rain forests or tropical high temperature, high humidity and shady valleys, which are cold-resistant flowers and plants. In general, when the temperature drops below 10 ℃, some varieties will suffer frost injury, scorched leaves, yellowing old leaves, drooping and falling off. Under the condition of static hydroponics, this phenomenon will also occur. Some flowers have strong cold resistance, such as ivy, vinca, fairy pen, etc., and grow normally under the temperature of 5 ℃ to 7 ℃. When the temperature is more than 30 ℃, the leaves of some flowers lose their luster, grow sluggishly, and have scorched brown spots on the leaf edge, showing a dormant state that can not bear high temperature, such as bamboo begonia, four seasons begonia, colored leaf grass and so on. Rotten roots are common in static water culture at high temperature above 30 ℃, which is also related to the decrease of dissolved oxygen in nutrient solution with the increase of temperature. The temperature is controlled between 15 ℃ and 28 ℃, which is suitable for all kinds of flowers cultivated in static water. In addition, it is also very important to understand the temperature needed for the growth of each kind of flower and to create a suitable temperature condition for it to grow in static hydroponics. Hydroponic flowers need light static hydroponics to choose more shade-resistant, shade-loving foliage flowers and a small number of flowering flowers. The characteristic of this kind of flower is that it does not need strong direct light during the growing period, and some flower varieties grow well in a more shady environment. Generally placed in the indoor, living room, office, as long as there are doors and windows through the scattered light and indoor lighting, can fully meet its needs for lighting. If the light is too weak, the leaves of flowers can not carry out normal photosynthesis, can not accumulate enough nutrition, poor growth. Some colored leaf flowers, such as colored leaf grass, variable leaf wood, etc. in a weak light environment, will lose the color of the leaves and become dull, this kind of flowers can maintain the luster of leaf color only in the environment where the light is more sufficient and is not directed by strong light.
Plant growth has phototaxis, the orientation of flowers should be rotated regularly, this work can be combined with cleaning utensils and changing nutrient solution, and the flowers after root cleaning can be rotated 180 degrees relative to the original orientation, so that the flowers will not grow on one side, and the top tip will always be straight and straight upward. Moist environment and good ventilation the origin of foliage flowers is mostly warm and humid environment. Static hydroponics also need to create a relatively humid environment in order to make it grow well. The simple method is to spray on the leaves of flowers (in order to prevent the spray from soaking the furniture, you can move to the balcony or outdoor operation, and then move the flowers to the indoor display after spraying). It is best to use a fine hole sprinkler when spraying, so that the spray beads stick to the leaves and do not flow down. Stronger flower leaves with wax film, such as tortoise back bamboo, gentleman orchid, can be wiped with wet towels, which can not only increase the humidity of the leaves, but also remove dust from the leaves. For those larger, difficult to move flowers, you can use a shallow dish or basin to hold water next to the flowers, evaporation of water can also increase the humidity of the environment. There should be a good ventilation environment. This is an important condition for the normal growth of flowers, static hydroponic flowers are installed in the room, if the doors and windows are closed, the air is turbid, it is disadvantageous to its growth. In particular, people go to work and leave home during the day, do not open doors and windows, and some even close curtains. In such a harsh environment, hydroponic flowers can not get the necessary light, even lack of fresh air, dissolved oxygen continues to decrease, and their growth will get worse and worse. The phenomenon of leaves yellowing and shedding, and thin and shrunken shoots. Where hydroponic flowers are placed, doors and windows should be opened regularly to form air convection, allowing fresh air from the outside to enter the room, which can increase the content of dissolved oxygen in the nutrient solution. An air-conditioned room can of course reach the temperature needed for hydroponic flowers, but the dry air in the room will cause thin flower leaves with scorched edges and withered tips. Air-conditioned rooms are also short of fresh air, which reduces the content of dissolved oxygen. It should be ventilated timely, which is beneficial to the growth of hydroponic flowers and human health. There are places with large-scale hydroponic flower furnishings, it is more necessary to do this work well.
Prevention and control of diseases and insect pests of hydroponic flowers
Hydroponic culture can get rid of the infection of soil diseases and insect pests, but it does not grow in the vacuum environment after strict disinfection, and it will still be damaged by environmental diseases and insect pests. Fungi, bacteria and viruses in the air can still infect the stems and leaves of hydroponic flowers, making them suffer different degrees of pathological changes. Aphids and shell insects can float indoors with the wind and fall on hydroponic flowers to suck juice. Moths lay eggs on flowers, hatch into larvae, and eat the tender leaves and stem tips of flowers. Take off the basin to wash the roots to static hydroponic flowers, will also carry fungi, bacteria, viruses, eggs, larvae, etc., if not carefully checked and cleared, it will leave hidden dangers. Static hydroponic flowers because of the particularity of their display environment, once the occurrence of diseases and insect pests, it is not suitable to use chemical pesticides to kill insects, nor can they be sterilized with large doses of fungicides.

Non-infectious disease is not caused by pathogen infection, it is caused by unsuitable environment. Muggy high-temperature weather in summer, cold winter, dry climate, scorching sun, obstructed air environment, excessive shade, excessive concentration of nutrient solution, or can not be evenly absorbed may cause static hydroponic flower leaf tip scorch and scorch, lower leaves yellowing and falling off. Hot summer temperature is too high, due to a sharp decline in dissolved oxygen in the liquid, and prone to root rot, which is a common symptom of static hydroponics. According to the above different symptoms, find out the corresponding causes, correct them, improve the cultivation environment, and avoid the occurrence of non-infectious diseases. How to maintain the still hydroponic flowers with disjointed and rotten roots? Due to improper management, or rotting roots due to hypoxia, or infected by fungi, bacteria and viruses, hydroponic flowers have leaf spot disease, leaves yellowing and falling off, resulting in disconnection of the lower end and loss of ornamental value. The hydroponic flowers with disjointed and rotten roots can be treated by the method of plant renewal.

The disjointed branches at the lower end can sprout new buds in the stem nodes as long as they do not rot, and they can be cultivated in nutrient solution at this time. Fugui bamboo, green pineapple, colorful plantain, taro, and so on, can all use this method. How many hydroponic flowers are arranged for the cultivation of hydroponic flowers in the livable room, which can not only regulate the mood, beautify the environment, but also purify the air, it is beneficial to install a few plants properly. The living room area is not large, and there are too many flowers, causing flowers to compete with people for oxygen at night. So how many flowers should be put in the room? According to the scientists' experiments, it is considered that it is more appropriate to plant one or two kinds of flowers for every 10 square meters according to the area of the room. According to this standard, it is estimated that the rooms with an area of 50 square meters to 60 square meters are equipped with more than 10 hydroponic flowers of different sizes, which can not only satisfy the viewing, but also will not cause the flowers to compete with people for oxygen at night.
How to choose hydroponic flowers in winter
Hydroponic flowers are very popular because they are clean, beautiful and easy to take care of. When choosing hydroponic flowers in winter, we must pay attention to the following four "points":
First, it is necessary to choose flowers that are suitable for hydroponic culture. If you buy back a species that is not suitable for hydroponic culture, it will not take long for the root to rot and gradually die. Aquatic plants, wet plants and a number of less drought-tolerant terrestrial plants are more suitable for hydroponics, such as Upland grass, taro, green apple, taro, Phyllostachys pubescens and so on.
Second, we should choose the flower species with strong cold resistance. Although some flowers are very suitable for hydroponic culture, they need a higher temperature to survive the winter, so it is difficult to survive the winter safely in ordinary families and is vulnerable to frost damage. The flowers with strong cold resistance and a little cold protection can survive the winter, such as tortoise back bamboo, purple leaf duck rubbing grass, aloe, hanging orchid, parasol grass, pocket coconut, brown bamboo and so on.
Third, flowers that have adapted to hydroponic conditions should be selected. After some florists get the soil out of the soil, they wash the soil from their roots and supply the flower market immediately. Although such flowers seem to grow normally, they have to go through a process of adaptation before they can grow normally in a hydroponic environment, so they must be carefully identified when they are purchased. Some white aquatic roots grow at the root or stem base of flowers that have adapted to hydroponic conditions.
Fourth, choose plants that are robust and free from diseases and insect pests. The plants with tall and straight branches and leaves and full and glossy leaves are helpful to reflect the appreciation effect of flowers.
The advantages of hydroponics
1. Daily management is simple.
The daily management of hydroponic flowers is very simple, except for changing the nutrient solution every 10 days during the peak period of plant growth in spring and summer, and every 15-20 days in autumn and winter, it does not need extra care. You only need to spray water on the leaf surface in the dry season or in the air-conditioned environment; wipe it with a clean cloth or paper towel when there is dust on the leaf surface. It saves the trouble of fertilizing, changing soil and watering water every day, and is very suitable for the fast-paced life style of people in modern society.
2. Clean and fashionable
As hydroponic flowers are completely separated from the soil cultivation environment and grow directly in a relatively aseptic or bacteria-free nutrient solution environment, they will not pollute our living environment like soil-grown flowers because of parasitic pests and germs in the soil. make our homes safer, cleaner and more at ease. And because we are separated from the soil, we can use more and more beautiful vases, utensils, and materials to grow. We can appreciate not only flowers and leaves, but also the process of root growth and their beauty, which we do not often see. Very neat and fashionable.
3. There are many kinds of application, and the technology is easy to master and operate.
As a result of conquering the adaptation technology of plant roots from native environment to aquatic environment, "Water Flower King" does not need to grow aquatic roots through planting baskets, nor does it need early computer and electric field mutagenesis, but only needs to do very simple technical treatment. Soil roots can be quickly transformed into aquatic roots, and anyone can grow exuberant and luxuriant hydroponic flowers, which greatly shortens the production cycle. It saves the production cost, makes the product have more profit space, and increases the competitiveness of the product in the market. At the same time, because of the low production cost, more and more people can enjoy the lifestyle brought by new technology and rapidly expand their market share. Because the planting basket is not used, hydroponic flowers become more beautiful and refined. Because Rain Water will change the concentration and PH value of the nutrient solution, hydroponic flowers are not suitable for planting in the open air, so some light-loving plants are more difficult to carry out indoor hydroponic culture at home, but the common shade / semi-shade flowers are basically able to carry out successful hydroponic cultivation, and there are nearly 400 experimental varieties at present. If you have a sunlight or artificial greenhouse, then in theory, any plant can be hydroponically cultured, but with different degrees of difficulty.
4. green and environmentally friendly, flower fish can be raised together.
The "Water Flower King" nutrient solution does not contain toxic ingredients, so it can be raised together for a long time without any side effects that are not conducive to flowers or fish. the fish in our store still grow well after long-term rearing. And some guests add nutrient solution to the aquarium to fertilize the aquatic plants, the effect is also very good, practice has proved that it is safe and reliable. At the same time, because of the special ingredients, it is not easy to breed mosquitoes in the nutrient solution, and if you pour the discarded nutrient solution into your soil to plant potted flowers when you change water, there will be a more unexpected surprise. Facts have proved that "Water Flower King" nutrient solution is a real green and environmentally friendly nutrient solution, and the effect is very obvious.
Selection of hydroponic Flower species
The growth and development of flowers need appropriate conditions such as water, oxygen, nutrients, light, temperature and so on. Water as a hydroponic medium contains a certain amount of oxygen. As long as the light and temperature are appropriate, timely supply of nutrients needed for plant growth, flowers can grow normally in water.
Due to the relationship between ecological habits and organizational structure of flowers, different flowers have different requirements for oxygen content in water. Some flowers have aerated tissue in the body, and the oxygen produced by these plants during photosynthesis can be sent to the root part of the plant through the aerated tissue for breathing; some flowers have aerial roots in the stem nodes, which means that aerial roots can absorb the oxygen plants need from the air; although some flowers do not have simultaneous tissue and aerial roots that absorb oxygen, they are well adapted to hydroponic conditions. However, the oxygen content in the water of some flowers can not meet the needs of their normal growth and development, so this kind of flowers is not suitable for hydroponics. Therefore, in order to make hydroponics successful, we must choose flower species that can adapt to hydroponics conditions, and do not plant them blindly, so as not to lead to the failure of hydroponics.
Flower species adapted to hydroponic culture
Araceae
Araceae flowers have great adaptability to horizontal conditions, when cultured with water, most of them can take root and grow rapidly in a short time, and quickly form a certain ornamental plant shape; after washing with soil, most of the roots can adapt to the hydroponic environment. Araceae flowers adapted to hydroponic culture are green pineapple, Guangdong evergreen, Daifen evergreen, silver emperor, golden queen, tufted spring feather, mini tortoise back bamboo, tortoise back bamboo, silver bract taro, emerald, Xi Lin taro, Qin leaf Xi Lin taro, green emperor Xi Lin taro, synthetic fruit taro, sea taro, crane flower, jadeite and so on.
Caryophyllaceae
Almost all the flowers of the family Commelina can adapt to hydroponic culture, such as purple leaf, purple back evergreen, light bamboo leaf, hanging bamboo plum and so on, which can take root and grow quickly when they are planted in water.
Liliaceae
The vast majority of lily flowers can adapt to hydroponic culture, such as aloe. Triangular aloe, dot pattern 12 volumes, hanging orchid, Zhu banana, dragon blood tree, horsetail iron, tiger skin orchid, tequila, Phnom Penh rich bamboo, sea onion, silver edge evergreen, silver edge step grass and so on.
Sedum family
Crassulaceae flowers are also more suitable for hydroponic conditions, such as: Lotus palm, hibiscus palm, silver wave brocade, gemstone flower, rooting and so on.
In addition, flowers that can adapt to hydroponics include peach leaf coral, parasol grass, colored leaf grass, purple goose velvet, blue pine, bamboo begonia, Begonia, emerald, gentleman orchid, aristolochia, variegated wood, silver chrysanthemum, fairy pen, leaf cactus, triangular bamboo, pineapple, Ji pineapple, golden millet orchid, rock vine, keel, color cloud pavilion, flower vine periwinkle, red back cinnamon, Sihai wave, ivy, ivy, palm bamboo Pocket coconuts, etc.
When selecting hydroponic flower species, in addition to considering the conditions of hydroponic culture, we should also pay attention to the following factors:
Although some flowers are well adapted to the conditions of hydroponic culture, the overwintering temperature is relatively high, for example, the overwintering temperature of some species of evergreen and variegated trees is more than 15c, and the overwintering temperature of green pineapple, taro, Phnom Penh rich bamboo and dragon blood trees is also above 10c. This is certainly not a problem for rooms that are heated in winter, but it is very difficult for most families to get these flowers safely through the cold winter. Although some flowers will not lead to the death of the whole plant after overwintering, due to the influence of low temperature and freezing injury, the leaves of the plants will become wilted, lose their due luster, the leaves turn yellow, the leaf tips or leaf edges become scorched, or new scorch spots appear on the leaves, and even cause a large number of defoliation or some branches and leaves to die, thus losing the value of appreciation. Therefore, when there are no more stable conditions for domestic mosquitoes, we must pay attention to the selection of flower species with strong cold resistance. The flowers suitable for hydroponic culture in ordinary families are:
Flowers with strong cold resistance
Such as evergreen, rattan, brown bamboo, tequila, peach leaf coral, gemstone flowers, sea onions, flowers and leaves along the steps, etc. can withstand the low temperature of about 0c.
Flowers with a certain degree of cold resistance
Such as tortoise back bamboo, purple leaf duckweed, light leaf bamboo, aloe, hanging orchid, silver wave brocade, parasol grass, purple velvet, silver chrysanthemum, golden millet orchid, Caiyun Pavilion, flowers and leaves vine periwinkle, ivy, pocket coconut and so on, you can survive the winter safely with a little protection when overwintering.
Of course, although some flowers, such as ruby taro, emerald taro, fruit taro, green apple, tiger tail orchid, and variable leaf wood, are safe and difficult to survive the winter, they are convenient to obtain materials, grow rapidly, and have high ornamental value, and can also be purchased and cultivated in the warm spring.
Yin tolerance problem
Due to the poor indoor lighting conditions, it is appropriate to choose flowers that prefer half-shade or tolerate half-shade. At the same time, even foliage plants that like half-shade or tolerate half-shade have different requirements for light intensity, such as variable-leaf wood, purple-leaf duckweed, hanging bamboo plum, etc., but white crane taro, hulk, Guangdong evergreen, silver emperor and so on all have a strong ability to tolerate shade. Due to the different lighting conditions of different rooms and rooms, the appropriate types of flowers should be selected according to the lighting conditions of the placement location, so as to ensure the normal growth of flowers and maintain good ornamental. When the light is insufficient, the branches and leaves of the plant are too long, the stem is thin, the internodes are longer, the leaves become smaller, abnormally small, lose green and lose their due luster, the leaves fade with colored spots, and even produce a large number of fallen leaves, thus seriously affecting the ornamental of flowers.
Water-raised orchid technology
Hanging orchid, the leaf color is fresh and green, the leaf shape is like orchid, fresh and elegant, it is a common family foliage flower that people like. In addition, it has the unique effect of purifying indoor air, which is one of the important reasons why people like to plant it indoors.
1. Container: container bottle can be single-layer or double-layer. Single-layer bottles are made of plastic bottles without bottom holes or ceramic bottles without bottom holes. In the double-layer bottle, the plastic screen is taken as the upper layer, and the lower bottle is a bottomless bottle. The hanging orchid is planted in the upper plastic screen to let the root of the hanging orchid droop in the bottle.
2. Take seedlings: remove the potted or ground-planted orchids from the pot or dig up from the ground, remove the soil from the roots, wash the roots with clean water, cut off the old and rotten roots, leave the fibrous roots, cut off some leaves (old leaves, leaves of diseases and insect pests), and leave strong leaves, generally leaving 6 to 10 leaves.
3. Pot up: the pot method of a single-layer bottle is to insert the treated hanging orchid into the bottle, fasten the bottle mouth with a sponge and insert a plastic straw for water transport. Let the orchid plant stand upright, fill the bottle with water and flower nutrient solution, and let the root of the orchid grow in water. In the double-layer bottle cultivation method, the plant of the orchid is planted on a plastic sieve, and the root passes through the small hole of the plastic sieve into the lower bottle, which is filled with pottery or stone rice (large grains) to make the orchid stand upright, and the lower bottle is filled with clear water and flower nutrition solution. After potting, put the orchid indoors or in a cool place for management.
4. Management:
① water: water and flower nutrient solution are added every 4 days for single-layer container cultivation, and the water is input from the straw until the water is full. Change the water of the double-layer bottle once a week, pour out the water when changing the water, wash the bottle clean, fill it with water and flower nutrient solution, and then put the plastic sieve on the bottle.
② fertilizer: adding water and changing water in the root and adding flower nutrient solution at the same time, topdressing outside the root is spraying branches and leaves with diluted flower nutrient solution every 3 days.
③ control of diseases and insect pests: if you find any diseases and insect pests, you can use universal powder and water to spray leaves.
④ to promote flowers: half a year after the flowering, do not spray water on the flowers, to prevent early falling flowers, flowers withered should be cut off from the branches to promote re-flowering.
The outstanding one in static hydroponics
There are more than 2500 species of Araceae belonging to 105 genera, which originated in tropical Asia and are produced in the waters or swamps of forest areas. after a long historical evolution, most of them have developed into terrestrial plants and few aquatic species. The common excellent ornamental plants (genera) in Araceae are: Candle, Dendrocalamus, Taro, unicorn, calla, evergreen, colorful taro, green velvet, bract taro, and so on. Although the above genera are terrestrial, they are closely related to aquatic vascular plants: some are wet species, some have aerial roots, some are prone to adventitious roots, and some are easy to develop ventilatory tissues under stress. Terrestrial plants are cultured in static water, and the root respiration is in a serious state of hypoxia. The prerequisite for its success is the correct selection of plant species, that is, it is closely related to aquatic plants. Araceae plants are closely related to aquatic plants, which are shown as follows: first, Araceae plants evolve and develop with aquatic genes as the center. According to the new Engler system, the most primitive genus in the Araceae is the genus Gladiolus, and the most evolved genus Gladiolus, both of which are aquatic plants. Acorus calamus is an aquatic or wet evergreen herb. it is the most primitive genus in the Araceae. It originated in the old tropics of the late Cretaceous (about 100 million years ago) and first appeared in the water environment. The genus Artemisia, which is the most evolved single genus in Araceae, is almost all over the freshwater waters of the old and new continents. It is a floating plant cultivated by nutrition, which is easy to migrate and spread and has a strong ability of proliferation. In addition, there are famous aquatic species such as Acorus calamus, taro and taro in Araceae. As an aquatic plant, the evolved genus Gladiolus is not a simple repetition of the original Gladiolus, but a dialectical "negative negation", a repetition on a higher basis. Although most species of Araceae grow on land, they all come from aquatic ancestors, which forms the "negation" of aquatic ancestors. In the end, it is transformed into a more advanced aquatic plant of the genus Magnolia, and this reply is once again "negative", that is, the dialectical law of "negative negation". It shows that the opposite poles of aquatic and terrestrial life have been unified in the dialectical development. This is the unique philosophical reason why Araceae plants are outstanding in static hydroponics. 2. Araceae belongs to the order Araceae, which has only two families, and the other family for the same purpose is Aquatic Pleuroidae, which is a floating or submerged herb. It is proved that Araceae and Pteropodidae share the same aquatic ancestors and have a very close relationship with each other. It can be seen that the plants of Araceae take aquatic genes as the center and evolve forward according to the approximate spiral curve. Third, the relationship of the order Araceae in the plant taxonomic system: the Hutchinson system believes that the order Liliformes evolved from the order Liliformes, while a few aquatic types of the order Liliformes have a parallel relationship with the marshes. The Tahta system believes that the order Araceae has a common ancestor with Palm order and Bana order (primitive lily), which can be traced back to Magnolia. Cronquist system believes that the order Araceae is closely related to the order Coleoptera and Palm, and has a common ancestor with the order Liliacea. From the above classification system, it can be inferred that the order Araceae is related to Liliformes and palms containing aquatic plants. To sum up, Araceae plants evolve forward with aquatic genetic genes as the center, have a common ancestor with aquatic planktonic families, and are related to lilies and palms containing aquatic species. Therefore, they contain aquatic genetic genes, which is the direct reason for making Araceae plants outstanding in static hydroponics.
Judgement and treatment of hydroponic rotten root
In the process of hydroponic culture, rotting roots are often caused by management and other reasons, such as too low temperature, excessive fertilization, diseases and so on. Rotting roots will make the water quality worse and affect the growth of plants. To judge whether the root is rotten, one is to smell the root with the nose, and if there is a bad smell, it proves that the root has rotted; the second is to smell the water, which means that the root system may also rot and deteriorate; and the third is to observe the appearance of the root system. If the root turns yellow and changes color, it means that the root system has been damaged. After the root system is rotten, gently pull the rhizosphere with your hand, and its epidermis is very easy to tear off, leaving only the lignified part.
After the emergence of rotten roots, to be cut off in time, generally rotten roots are gradually rotting upward from the tip, after pruning, until cut to the normal root system. After changing water, pay attention to observe that if rotten roots continue to appear, they should be dealt with in a timely manner.
Simple hydroponic facilities-- bottles and cans and cultivation management
The use of waste containers, such as beverage cans, jars, white polystyrene hard foam boxes (boxes), etc., with a little finishing, can become hydroponic carriers of different sizes and shapes, which can not only adjust measures to local conditions and make the best use of things, but also green the surrounding environment. It has the interest of returning to nature.
I. bottles and cans
1. Such as metal beverage cans, glass or plastic bottles, paper foil square beverage boxes, etc., are originally filled with liquid, as long as the original contents are washed and refreshed, they can be used as hydroponic carriers.
two。 Planting cup: according to the size of the mouth of the selected container, choose the plastic cold drink cup, which is exactly the size of the mouth 1 to 3, as the carrier of anchoring plants. As shown in figure 1, dig out the "well" hole at the bottom of the cup so that the root system can reach into the nutrient solution through the bottom of the cup, and the anchors of the plant will not leak out. The opening also has the function of breathability.
3. Plant anchoring: prepare a piece of non-woven cloth (non-woven cloth) for clothing padding about 8 × 12 cm, rinse off the soil gently and do not damage the root system. Wrap the root system with non-woven cloth, and then use porous plastic sponge (debris cut off from coat pads, sofas, seat cushions, etc.), or a small amount of rock wool and glass wool (used as thermal insulation materials, there are yellow, there are also yellow with white) and other coarsening, so that it can be stuffed into the plastic planting cup to anchor the plant. In fact, do not have the above-mentioned things on hand, the use of flower paste, after proper cutting can also be used as anchoring material. The non-woven rolls enclosing the roots, together with the exposed roots, are immersed in bottles and jars containing nutrient solution. It must be noted that the surface of the nutrient solution should have a space distance of not less than 1 cm from the bottom of the planting cup. This is the key to the success or failure of hydroponics. With the help of the osmosis of non-woven fabric, the nutrient solution continues to supply the root system with nutrition for about half a month, and the nutrient solution decreases gradually with the growth and transpiration of crops. When the liquid level drops to 1 top 4 of the container height, a new nutrient solution can be added. At this time, the distance between the liquid level and the bottom of the planting cup can be larger, about 3 centimeters.
4. Cultivation management: if you use a transparent glass container, you must cover the bottle with a shade to avoid direct sunlight to breed algae and compete with the culture for nutrition. In summer, in order to prevent a substantial rise in liquid temperature caused by sunlight exposure, it is best to have shading measures, or put in a place where the sun cannot be exposed directly.
2. Box class
1. Box: usually used as a shock-proof polystyrene white rigid foam box, or corrugated cartons, wooden cases with a certain strength can be used. It is generally about 35 × 25 × 15 cm and 60 × 40 × 16 cm. If there is a hole in the bottom of the box, it can be paved with wood or foam board. The box is lined with black agricultural film to prevent nutrient solution leakage. If it is confirmed that the box does not leak and does not penetrate light, the film can be avoided. If there is no black film, other films can also be used.
two。 Upper cover: the function of upper cover and fixing plate. Find a polystyrene foam board with the same area as the box and about 2.5 cm thick as the upper cover and fixed planting board. A certain number of planting holes with a diameter of about 6 cm are opened on the board. Like bottles and cans, as long as the selected plastic cold drink cup can be placed in it, it will reveal about 1 inch and 2 cups high. The number of planting holes depends on the size of the box. It is generally 6 to 16 acupoints. In addition, a small hole with a diameter of 2 cm is opened near the inside of the box near the side of the upper cover, which is used to peep the liquid level of the nutrient solution and to add the nutrient solution.
3. Planting cup: select materials and prepare the same bottles and cans.
4. Floating board: take a polystyrene foam board which is 2.5cm less than the net area of the box and 2.5cm thick as a floating board. There are regular holes with a diameter of 1cm to 2cm to increase the air content of the floating board and facilitate the root system to extend into the nutrient solution. The floating board is covered with a thin layer of rock wool (about 1 cm dry thickness), or glass wool of the same thickness, or 250g / m2 of non-woven cloth, which is used to absorb nutrient solution. When it is really impossible to get these things, medical sterilized skim gauze can also be used instead. The area of the cotton infiltration layer is about 6 cm more than that around the floating board, so that the excess part laid on the floating board can freely droop from around the floating board (like an apron) and soak into the nutrient solution to absorb the nutrient solution, so as to ensure that a wet layer with nutrient solution is formed on the floating board. The roots of plants can stretch freely on the floating board and have more direct contact with the air. Another part of the root system can still absorb nutrients through the four sides of the floating board or through the holes in the floating board into the nutrient solution. This method can make up for the unfavorable environment that the general hydrostatic culture can not circulate nutrient solution and oxygenation.
5. Cultivation management:
The main results are as follows: (1) pour the prepared nutrient solution into the cultivation box. At the beginning of planting, the liquid level should be slightly higher, and the floating board should touch the non-woven root roll protruding from the planting cup, so that the nutrient solution can be absorbed. The highest liquid level must have some space in the cultivation box. When the nutrient solution is reduced to 3-5 cm with the absorption and transpiration of the plant, the nutrient solution should be added until the liquid depth is about 10 cm.
(2) when the nutrients of the nutrient solution change greatly, or when there is precipitation, turbidity, stench and pathogen infection, the nutrient solution should be updated as appropriate until it is completely updated.
Requirements of hydroponic flowers for moist environment and good ventilation environment
The origin of foliage flowers is mostly in a warm and humid environment. Static hydroponics also need to create a relatively humid environment in order to make it grow well. The simple method is to spray on the leaves of flowers (in order to prevent the spray from soaking the furniture, you can move to the balcony or outdoor operation, and then move the flowers to the indoor display after spraying). It is best to use a fine hole sprinkler when spraying, so that the spray beads stick to the leaves and do not flow down. Stronger flower leaves with wax film, such as tortoise back bamboo, gentleman orchid, can be wiped with wet towels, which can not only increase the humidity of the leaves, but also remove dust from the leaves. For those larger, difficult to move flowers, you can use a shallow dish or basin to hold water next to the flowers, evaporation of water can also increase the humidity of the environment.
There should be a good ventilation environment. This is an important condition for the normal growth of flowers, static hydroponic flowers are installed in the room, if the doors and windows are closed, the air is turbid, it is disadvantageous to its growth. In particular, people go to work and leave home during the day, do not open doors and windows, and some even close curtains. In such a harsh environment, hydroponic flowers can not get the necessary light, even lack of fresh air, dissolved oxygen continues to decrease, and their growth will get worse and worse. The phenomenon of leaves yellowing and shedding, and thin and shrunken shoots. Where hydroponic flowers are placed, doors and windows should be opened regularly to form air convection, allowing fresh air from the outside to enter the room, which can increase the content of dissolved oxygen in the nutrient solution.
An air-conditioned room can of course reach the temperature needed for hydroponic flowers, but the dry air in the room will cause thin flower leaves with scorched edges and withered tips. Air-conditioned rooms are also short of fresh air, which reduces the content of dissolved oxygen. It should be ventilated timely, which is beneficial to the growth of hydroponic flowers and human health. There are places with large-scale hydroponic flower furnishings, it is more necessary to do this work well.
The light needed by hydroponic flowers
Static hydroponics choose more shade-resistant and shade-loving foliage flowers and a small number of flowers. The characteristic of this kind of flower is that it does not need strong direct light during the growing period, and some flower varieties grow well in a more shady environment. Generally placed in the indoor, living room, office, as long as there are doors and windows through the scattered light and indoor lighting, can fully meet its needs for lighting. If the light is too weak, the leaves of flowers can not carry out normal photosynthesis, can not accumulate enough nutrition, poor growth. Some colored leaf flowers, such as colored leaf grass, variable leaf wood, etc. in a weak light environment, will lose the color of the leaves and become dull, this kind of flowers can maintain the luster of leaf color only in the environment where the light is more sufficient and is not directed by strong light.
Plant growth has phototaxis, the orientation of flowers should be rotated regularly, this work can be combined with cleaning utensils and changing nutrient solution, and the flowers after root cleaning can be rotated 180 degrees relative to the original orientation, so that the flowers will not grow on one side, and the top tip will always be straight and straight upward.
How hydroponic Flowers survive the Winter safely
How to survive the winter of hydroponic flowers
In general, flowers dormant when they are below 5-8 degrees Celsius, and tissue necrosis occurs when they are below 0 degrees Celsius. Therefore, if the indoor temperature is above 5 degrees Celsius, hydroponic flowers can generally survive the winter safely; in winter in the south, the indoor temperature is generally not lower than 5 degrees Celsius, if the extremely low temperature weather occurs for a few days, it can be solved by lighting a 60-watt incandescent lamp above the flowers to solve the problem; while in the north, because there is mostly indoor heating, it can also meet the safety of hydroponic flowers to survive the winter.
Why do hydroponic flowers change water?
Because plants absorb water and inorganic salts from the nutrient solution, the nutrients in the nutrient solution will become less and less, and because of the respiration and metabolism of roots, there will be more and more harmful substances in the water. So hydroponic flowers should be replaced with a new nutrient solution after a period of growth. In fact, this and soil cultivation of flowers is the same reason, soil cultivation of flowers to fertilize and change the soil once a year is also the reason. Hydroponic flowers in the vigorous growth of spring and summer water change time interval is shorter, slow growth in autumn and winter can be longer.
Cyclamen hydroponics
Planting cyclamen in water has only begun to appear in Europe in the last year or two. Because this cultivation method makes cyclamen break away from the traditional flowerpot and matrix, it is clean and beautiful, and it can endow the blooming cyclamen plant with a variety of cultivation and application forms. As soon as it appears in the market, it has won the warm welcome of consumers. In fact, cyclamen is not difficult to grow in water. First of all, we should choose satisfactory cyclamen potted flowers and prepare containers for hydroponic cyclamen, so that when the preparation work is completed, we can begin to make hydroponic cyclamen. Hydroponic cyclamen should deduct the bought cyclamen potted flowers together with the substrate (flower soil) from the basin, put them under the faucet and wash the matrix clean with a gentle flow of water, or you can put the plant together with the matrix in a water basin filled with water. rinse the matrix in water, and then rinse it with tap water. Note that the action must be gentle in the whole process of removing the matrix to avoid damage to the roots of cyclamen. Washed cyclamen plants can be placed in a pre-prepared hydroponic container, plus water, beautiful hydroponic cyclamen is made.
It should be pointed out that there is no need to add any fertilizer to the water to cultivate cyclamen. The nutrients in the bulb roots of cyclamen can maintain the normal growth and flowering of cyclamen plants for 6 weeks. At the same time, the height of the water surface should be kept below the bulb. In general, according to the evaporation of water, water can be added to the container twice a week to maintain the height of the water surface.
In fact, in cyclamen hydroponics, cyclamen plant is only one of the factors. In order to make hydroponic cyclamen with distinctive characteristics and outstanding personality, it also depends on the selection of hydroponic utensils and the combination of cyclamen plants. It all depends on the producer's unique perspective and flexible creativity.
Water culture method of keeping ball orchid and root in water
The orchid has always been cultivated with soil. Through the experiment of exposed root hydroponics, it has the following characteristics: ① saving labor, ② sanitation, less ③ diseases and insect pests, simple ④ management, long flowering period of ⑤, and ⑥ appreciating leaves and flowers with considerable roots.
The method of water culture of dew root is:
(-) Seedling treatment: dig up the soil-grown orchids, wash them with clean water, cut off withered leaves and leaves of diseases and insect pests, and soak them in diluted flower nutrient solution for half a day.
(2) on the basin: take a glass bottle or vase (without bottom hole), put several beautiful river stones at the bottom of the bottle, move the treated orchid seedlings onto the river stone of the vase, unfold the roots, add clear water, add flower nutrient solution, and place them indoors or in a cool place.
(3) Management: first, spray leaves with clear water once a day, spray leaves with flower nutrient solution every three to four days after one or two days: change water on one side every 15 days, and add nutrient solution after changing water; third, one month after the pot, the head of orchid is injected with flower nutrient solution, half a milliliter at a time, and then once a month to promote growth, flowering and prolong flowering.
(4) it can blossom in about two to three months after potting. Flowers withered after pruning, change water, add nutrient injection, can blossom again.
There is a difference between hydroponic culture and hydroponic cultivation of flowers.
In recent years, some hydroponic and hydroponic flowers are favored by people because of their freshness and environmental protection, elegant style, easy maintenance and easy combination. On the face of it, hydroponic and hydroponic flowers are cultivated in the same form, that is, liquid conservation, so many people confuse the two. In fact, they are obviously different.
Flowers used for water culture generally have inflated bulbs, which are rich in nutrients, and their growth and flowering mainly rely on their own stored nutrients. During cultivation, it is only necessary to soak the roots in clean water and fix them without supplying nutrients. The main flowers suitable for water cultivation are daffodils, tulips, hyacinth, rich bamboo and so on. In order to make hydroponic flowers grow luxuriantly and blossom brightly, the key is to select fully developed bulbs to provide nutrients for their growth process; the second is to change water frequently and change water every 2-3 days (rich bamboo every 7-10 days) to maintain sufficient oxygen content in water and improve root activity; third, to maintain sufficient sunshine to make it grow healthily.
Hydroponic flower culture is to fix the plant root on the cover or floating board of the flowerpot and soak the root system in water, which must be equipped with reasonable inorganic nutrition, so flower hydroponics is also called nutrient solution culture. The habits and internal structure of flowers suitable for hydroponic culture are suitable for normal growth in water. At present, the main varieties cultivated are orchid, orchid, crab claw orchid, Brazilian wood, evergreen, clump taro, tortoise back bamboo, gemstone flower, hanging bamboo plum, rooting and other plants.
Northeast University of China has adopted bioengineering mutagenesis technology and has developed nine series of more than 500 species of hydroponic flowers after 8 years of efforts, including both herbaceous flowers and woody flowers, cacti and succulent plants. It also includes flowering flowers such as orchid and Phalaenopsis. With the progress of technology, some high-grade flowers introduced from abroad in recent years, such as pineapple, Anthurium andraeanum, Zhu Dinghong, etc., have also successfully realized hydroponic culture. There are also some flowers with Chinese characteristics, such as tiger tongue orchid, etc., have also been domesticated by hydroponics.
The root characteristics of hydroponic flower plants have changed, root hairs have degenerated, and most of them are vertical straight roots, unlike hydroponic plants whose roots and root hairs are reticulated. After aquatic mutagenesis, the aquatic root gene of plants has been expressed, so the leaves of real aquatic flowers will increase and thicken, and the leaves and branches will be more fresh and tender than those growing in the soil.
The key to hydroponic flower culture is to prepare a good nutrient solution. Do not use metal containers or containers containing grease, acid and alkali in the preparation of nutrient solution. When using tap water to prepare nutrient solution, a small amount of humic acid compounds should be added to treat chlorides and sulfides in the water. Hydroponic flowers are added or changed once a week, and the pH value should be controlled between 5.5 and 6.5. The nutrient solution can be used as fertilizer for other crops.
Brief introduction of Flower hydroponic Culture Technology
Hydroponic culture of flowers is a common kind of soilless cultivation, there are many methods, several commonly used are briefly described as follows.
The deep liquid flow technique is characterized by the fact that the root system of the plant is wholly or partially immersed in the nutrient solution; the nutrient solution is mobile; the nutrient solution is mixed with air to dissolve oxygen.
Nutrient film (NFT) technology is developed on the basis of plastic bag technology. The plant can be cultivated by putting an appropriate amount of nutrient solution into the plastic bag, and on this basis, the plant can be further improved: the plastic bag is changed into a plastic film and laid on a grid of a certain shape; the nutrient solution is a thin layer 0.3 to 1.0 cm thick; part of the root system of the plant is immersed in the nutrient solution and part of it is exposed to moisture; the nutrient solution flows; the plastic film wraps the plant in white and black, forming a dark space inside.
The advantages are as follows: the oxygen demand of root respiration is well solved; the structure is simple and portable, the cost is low; the plant grows fast, is easy to manage, and is suitable for large-scale production.
In the technology of aerosol culture, the nutrient solution is sprayed around the plant roots after atomization, the fog condenses on the surface of the roots, and water is absorbed by the roots. The root is continuous or discontinuous in the environment of nutrient droplet saturation, which well solves the problem of water, nutrient and oxygen supply, and the plant production is fast. Fog culture can also be used in cutting seedlings.
The water solution of glass bottle can be coated with black plastic film around the bottle, or covered with black paint, or pasted with a layer of black paper, so that the bottle is opaque. Shading is beneficial to root growth and avoid algae growth. In summer, a layer of white paper should be placed on the outside of the black bottle to cool down. Tear off the white paper in winter, use foam board to do bottle cap, open a hole in the middle, clip the plant, cover the bottle cap, the top of the cap should also be black. Fill the bottle with nutrient solution, not too full, and leave pores for plants to breathe oxygen. If the water is inserted to promote the root, it is not necessary to use the nutrient solution, as long as the water can be injected, and then change the nutrient solution after the root grows. Specific operation process:
The seedlings can change the nutrient solution once a week according to the situation. Adult flowers are changed once a week in the summer peak growing season and once in 1 to 2 weeks in the non-growing season.
Take a breath and open the bottle cap for a while every morning and evening, leaving the roots completely exposed to the air. After a period of adaptation, there can be no ventilation for more than one month.
Rehydration flowers grow vigorously in summer and consume a lot of water, so you should always replenish water in the bottle to prevent the nutrient solution from drying up.
The preparation of hydroponic nutrient solution can be made with fertilizer tablets sold on the market or chemical fertilizers. If there are conditions, you can prepare it by yourself, and the formula is as follows:
Formula 1: (PH value 6mur6.5)
Potassium dihydrogen phosphate 0.44g / L; potassium sulfate 0.14g / L; calcium nitrate 0.59g / L; ammonium nitrate 0.19g / L; magnesium sulfate 0.53g / L; trace elements 2ml; Fe-EDTA2 ml.
Formula 2: (PH value 6Mui 65)
Calcium nitrate 1.64g / L; magnesium sulfate 0.98g / L; potassium nitrate 1.01g / L; trace elements 2ml; potassium dihydrogen phosphate 0.27g / L; Fe-EDTA2 ml.
Preparation method of trace element solution:
Boric acid 2.86g, zinc oxide 0.11g, manganese chloride 181g, copper dichloride 0.05g, sodium molybdate 0.025 g. The above drugs are dissolved in 800ml of water and then dissolved to 1000 ml.
Multi-method hydroponic culture of flowers
① water interpolation is the simplest and most successful method. Cut off a part of the stem and branch from the selected flower mother plant, insert it into the water, take root and sprout in a suitable environment and grow into a new plant. When cutting branches, they should be cut at 3-5 mm below the node, and the cross section should be flat and there should be no longitudinal cracks. When cutting branches with aerial roots, the aerial roots should be protected and inserted into the water. Green pineapple, rich bamboo and so on are suitable for hydroponic culture.
② root washing method: select flowers with ornamental value, strong growth, soil cultivation (or other media) formed flowers, remove soil, wash roots and change to hydroponic culture, it is best to use flowing water when washing roots. The washed flowers are planted in prepared utensils and injected with tap water that does not pass through the root system. Initially change the water once a day, wash the roots and utensils at the same time, and reduce the number of water changes after a week. Waiting for the cultivated flowers to grow new roots in the water shows that they have adapted to the hydroponic environment and can change the water every 7-10 days or even longer.
③ stripping method of tillering buds: suitable for flowers with strong tillering ability, such as orchid, pineapple and so on. The method is simple and the survival rate is high. Select the larger tiller bud, remove the connection between the upper soil and the mother plant, peel the tiller bud off the mother plant (protect the root of the tiller bud) with hand or sharp blade, wash the soil attached to the root, and cultivate it by hydroponic culture.
④ picking stem small plant method: some flowers grow in the growth process, there are one or more small plants on the walking stem, most of them have a small number of fully developed roots, such as Cymbidium and pineapple have this characteristic, take advantage of this characteristic of flowers, pick the shaped plantlets hydroponic culture, very simple.
Hydroponic flowers should choose tortoise back bamboo, gentleman orchid, green apple, iron orchid, Guangdong evergreen, purple back evergreen, rich bamboo, hanging orchid and bulb flower tulips, lilies, hyacinth, Zhu Dinghong, calamus orchid and so on.
Strategies for the difficulties of hydroponic Flower cultivation in Summer
First, where are the difficulties of hydroponic flowers in summer?
Answer: hydroponic flowers are used to cultivate ornamental plants in a non-solid medium (water or adding an appropriate amount of plant nutrient solution to water). At present, most of the hydroponic flowers in the family are cultivated in still water, and the dissolved oxygen is lower than 1mg/l, and the flowers barely maintain life in anoxic utensils. With the increase of temperature in summer, the vigorous physiological metabolism of plants, the multiplication of microorganisms, the sharp increase of oxygen consumption, the continuous decrease of dissolved oxygen and the deterioration of water quality, many unfavorable factors are formed for the growth of hydroponic flowers, which may cause root rot and wilting of branches and leaves. even kill the whole flower. Therefore, in summer, in addition to preventing heat and high temperature, increasing the oxygen content of nutrient solution is the key to ensure the safety of hydroponic flowers in summer.

Second, how to improve the content of dissolved oxygen in nutrient solution?
Answer: there are many ways to increase dissolved oxygen, which can be summarized as chemical method and physical method. The following are several methods that are easy to operate and effective.
1. Increase the number of times to change nutrient solution
Changing the nutrient solution is the easiest way to increase dissolved oxygen. According to the measurement, the dissolved oxygen content of the fresh nutrient solution is 70%-90% higher than that of the original solution, which can improve the physiological hypoxia of flowers in time.
Flowers that have taken root in water are suitable to change the nutrient solution no more than 7 days in 3-5 days. When changing the nutrient solution, pay attention to the temperature difference between the new solution and the original solution should not be too large, too large temperature difference may cause flower root physiological disorder.
When changing the liquid, we should patiently rinse the roots with clean water, remove withered and rotten roots, and truncate the aged roots to promote the growth of new roots.
If the nutrient solution suddenly becomes turbid, or there are mosquito eggs or mosquito breeding, you should immediately replace the new nutrient solution.
two。 Vibrating oxygenation
For hydroponic flowers with smaller utensils, as long as the root system is clear and the nutrient solution is clear, the vibration method can be used to increase oxygen by fixing the flowers with one hand and gently shaking the utensils with the other hand. After shaking, the dissolved oxygen content of the nutrient solution can be increased by more than 30%.
Hydroponic flowers with turbid nutrient solution and stunted root system should not adopt the method of vibrating oxygen enrichment, and the nutrient solution must be changed thoroughly.
3. Using automatic water exchanger for hydroponic flower culture
The content of dissolved oxygen in flowing water can reach 8~12mg/l, but only 1mg/l in still water. The automatic water changer for hydroponic flowers is designed and made according to this principle. The whole frame is a flower cultivation vessel, which is equipped with a miniature circulating pump. The outlet end of the pump is connected to the set pipe, and the nutrient solution circulates in the pipe when working, increasing the dissolved oxygen for the absorption of flowers. After the pump stops working, the root system maintains a certain liquid level. There is no doubt that the cultivation with automatic water changer is to soak hydroponic flowers in the "oxygen bar", and its growth is obviously better than that of static hydroponics.
The cleaning and changing liquid of hydroponic flower automatic water changer is generally once every 30 to 35 days.
4. Inflate a vessel
If there is a tank of ornamental fish next to the aquarium while cultivating flowers, you can use the spare outlet pipe of the fish tank air supply pump to connect the rubber pipe and put the sand head into the static hydroponic flower utensils to inflate (the airflow is not too large, so as not to splash the nutrient solution), and the effect is also good with the flow of air to increase oxygen.
Third, where should hydroponic flowers be placed in summer?
Answer: most of the flowers selected in hydroponic culture are shade-resistant foliage flowers and flowers and leaves and ornamental flowers. Such as taro, white jade evergreen, silver taro, candle, pineapple and so on. These flowers like to be warm and humid, slightly resistant to shade, and avoid high temperature and dry heat. "hydroponic culture" only changes the cultivation form, but it is impossible to change its growth habits and the required environmental factors. It is best to put hydroponic flowers in bright light, slightly higher humidity, cooler and well-ventilated environment in summer. Avoid direct sunlight, but can not be too shaded, so as not to hinder the photosynthesis of flowers, weaken growth, elongate stem nodes and thin leaves. Resulting in colored blocks, colored flower leaves lose their luster.
Can hydroponic flowers be placed in an air-conditioned room?
A: yes. However, hydroponic flowers should not be placed in the air outlet of the air conditioner, the wind speed is too fast will hurt the branches and leaves, light leaves curl, heavy scorched edge withered. It is also considered that the temperature requirement of flowers during the day is higher than that at night. If the air conditioner is turned off at night, the ambient temperature is higher than the daytime temperature when the air conditioner is turned on, which is disadvantageous to the growth of hydroponic flowers.
When turning on the air conditioner, put a basin of water next to the flowers or spray to the leaves to increase the environmental humidity. The flowers are placed far away from the air outlet of the air conditioner, and there is no problem that the temperature difference between day and night is small.
Fifth, what about the rotten roots of hydroponic flowers?
A: as the air temperature continues to rise, the water temperature will also rise, microbial culture will accelerate, dissolved oxygen will decrease, and the water quality will deteriorate. Improper addition of nutrient solution and too high dissolved concentration may lead to root rot of hydroponic flowers, especially Zhu banana of Liliaceae, horsetail iron (fine leaf millennium wood) and five-colored millennium wood.
Flowers with rotten roots can regain their growth by using the following methods:
① removes all the rotting roots, and the infected part of the stem should be cut off with a sharp knife.
②-trimmed flowers were immersed in 0.5% potassium permanganate solution for 10 minutes and 20 minutes to sterilize.
③ takes out the soaked flowers and rinses them in running water.
The flowers washed by ④ are put into the original utensils and cultivated in clean water (the utensils should be washed).
⑤ every two days to change the water, only change the water without nutrient solution. The water quality is clear, which can reduce the number of water changes. New roots can sprout after 10-15 days.
The newly sprouted roots of ⑥ were still cultivated in clear water, when the temperature was stable at 18-25 ℃, and cultivated in nutrient solution.
Sixth, how to breed algae in nutrient solution?
Answer: algae in nutrient solution is a common phenomenon in the process of hydroponic flower cultivation. Especially in summer, high temperature, good transparency of utensils, bright environment, or changing nutrient solution for too long, will lead to a large number of algae breeding. Algae and flowers take oxygen, and secretions pollute the solution, resulting in a decline in the quality of nutrient solution. The algae attached to the flower roots hinder the respiration of the roots and interfere with the normal physiological activities of the flowers.
Once the nutrient solution breeds algae, decisively pour out the contaminated solution, thoroughly wash the utensils, brush off the algae attached to the roots, and replace the new nutrient solution.
At present, Chinese scientists are studying a kind of "algae-eating insect", which can filter and feed on algae, which is called the natural "nemesis" of algae damage. Once the experiment is successful and popularized, a small amount of "algae-eating insect" can be put into the hydroponic flower nutrient solution to eliminate the breeding of algae.
The reproduction of algae depends on good light. Use baffles or old newspapers to cover hydroponic flower utensils to avoid direct light, and the chances of algae breeding will be relatively reduced.
What kind of fertilizer is used for hydroponic flowers? How to fertilize in summer?
Answer: hydroponic flower is a special cultivation form, which belongs to a cultivation method of soilless cultivation. The root system of flowers is anchored in water (or special plant nutrient solution), also known as nutrient solution cultivation.
Hydroponic flowers should be cultivated with matching plant nutrient solution. However, different flowers need different nutrient elements at different growth stages. if five, six or even more than a dozen bottles of hydroponic flowers are cultivated at the same time, and the varieties are different, it is not realistic to buy a matching bottle of plant nutrient solution for each kind of flower. For simplicity, you can choose to use a universal plant nutrient solution.
The general-purpose plant nutrient solution generally contains all the nutrient elements (including a large number of elements and trace elements) necessary for flower growth, the proportion of various elements is balanced, and the inorganic salt is in an ionic state, which has a wide range of application. it is suitable for the nutrient needs of different flower varieties in the growth stage, and the non-toxic, harmless, pH value and ion concentration are conducive to nutrition absorption.
There are many kinds of plant nutrient solution sold in the market, the good and the bad are intermingled. It is best to go to the hydroponic flower store to buy reputable products from manufacturers.
There are different opinions on whether to cultivate with nutrient solution or only with clear water in summer. according to the author's experience, the flowers with high temperature tolerance and strong growth are cultivated with nutrient solution, and the flowers with slender roots and semi-dormant or dormant temperature at about 30 ℃ are cultivated only with clear water. Such as silver taro, green pineapple, mini tortoise back bamboo, ruby, Xi Lin taro, etc., cultivated with nutrient solution is suitable to maintain the growth advantage and enhance the ornamental taste. Colorful leaf grass, bamboo crabapple, pineapple and other flowers, a bottle of water can safely spend the summer.
The allocation of nutrient solution should be in strict accordance with the proportion indicated in the instructions, and the concentration should not be increased at will. Because the root tissue structure of flowers germinated in hydroponics has changed, which is looser and larger than that of soil cultivation. The cell wall becomes thin and absorbs water, nutrients and oxygen directly from the nutrient solution. It is extremely sensitive to the concentration of the nutrient solution, and too high concentration is harmful to flowers. As long as the concentration of a large number of elements is not lower than the level of 1 liter of micro-friction, lower concentration is beneficial to the growth of flowers.
It is appropriate to change the nutrient solution every 5 days in summer.
Can you change soil-grown flowers into hydroponic flowers in summer?
Answer: soil-cultivated flowers are hydroponic flowers, which is the most suitable in spring and autumn, when the temperature is about 15-25 ℃, which is suitable for flower growth and easy to adapt to the changed cultivation environment. The following factors should be considered in order to change the cultivation form of flowers in summer: ① selects the quality that is closely related to wet flowers. The flowers with normal growth and sound development are still growing normally when the temperature of ② is about 30 ℃. The experiment shows that the survival rate of Amorphophallus, mini-tortoise-backed bamboo, ruby Amorphophallus, Hulk, green pineapple and some pineapple flowers is higher in summer from soil cultivation to hydroponic culture, they adapt to hydroponic environment quickly, and their roots rarely rot. After 15-20 days cultivation, not only the lateral roots of the old roots, but also the end of the rhizome can germinate hydroponic roots.
When changing from soil cultivation to hydroponic culture, the soil in the rhizosphere of flowers should be cleaned up. Rinse repeatedly to protect the root system from damage or damage. Take containers with large capacity for cultivation, change water once a day, five days later, change water once every 2-3 days, water roots grow to 5 cm long, and cultivated with low concentration plant nutrient solution.

Methods for obtaining hydroponic materials
Wash the roots with potted plants
Hydroponic culture of rhododendron
Soilless cultivation is characterized by replacing soil with man-made substrates. The soilless cultivation of rhododendron with solid substrate in Hunan Forestry Institute has achieved very satisfactory results. The variety is summer cuckoo, the crown structure of soilless cultivation is compact, the number of flowering is large, the flower diameter is large, and there are few diseases and insect pests. It not only improves the quality of flowers, but also greatly reduces the heavy physical work, so it is a cultivation method worth popularizing.
1. Preparation of matrix
The root system of rhododendron is very slender, which requires loose matrix to facilitate air permeability and drainage. 1 part of vermiculite, 1 part of pearl sand, 1 part of river sand and 1 part of cinder were mixed in proportion. After mixing the substrate, sterilize it with 0.1% carbendazim solution, mix it evenly into the substrate and cover the plastic film for 1 day. Then rinse with clean water for many times, dry, mix well with 0.4% agricultural compound fertilizer solution, then cover it with plastic film for a month, and then use it in the basin.
two。 Preparation of nutrient solution
Azaleas have strict requirements for fertilizers. During the growing period, thin fertilizer is applied diligently. According to the experiment, good results can be obtained by spraying low concentration foliar fertilizer with agricultural compound fertilizer as the main fertilizer, supplemented with trace elements, PH value controlled at about 5.
The preparation of a large number of elements: 1 liter of water plus 2 grams of agricultural compound fertilizer and 0.5 grams of magnesium sulfate is the standard solution.
The preparation of trace elements: 1 liter of water plus 20 grams of disodium ethylenediamine tetraacetate, 15 grams of ferrous sulfate, 4 grams of manganese sulfate, 6 grams of boric acid, 0.2 grams of zinc sulfate, 0.1 grams of copper sulfate and 0.2 grams of ammonium molybdate as mother liquor. When in use, 1 liter of standard liquid and 1 ml of trace element mother liquid are all elements. The preparation of foliar fertilizer: 1g urea, 1g potassium dihydrogen phosphate, 0.02g boric acid and 0.1g V.B1 in 1 liter of water.
3. Water and fertilizer management
Because the substrate has good drainage and air permeability, but the water retention is poor, so the amount of water is generally more than that of soil culture, in order to keep the substrate moist; at this time, pregnant buds and leaf buds germinate, requiring a large amount of fertilizer, and the full amount of nutrient solution is poured once in about 10 days. From March until the buds burst, foliar fertilizer is sprayed every 15 days or so. After flowering, there is a large amount of water, in addition to watering every day, foliar watering should be carried out in the evening. At this time, the amount of fertilizer is also large, so it can be changed to irrigate the nutrient solution once a week and spray foliar fertilizer once a week to promote the sturdiness of new branches and facilitate flower bud differentiation. After the ambush, pay attention to keep the substrate moist, and sprinkle water to the leaf surface, the amount of fertilizer can be reduced to about 20 days to pour nutrient solution. After the autumn is cool, you can gradually increase the amount of fertilizer, apply a full amount of nutrient solution once in half a month, and spray 1 Mel foliar fertilizer twice to promote the robust growth of flower buds. After the beginning of winter, the physiological activity of rhododendron is weak, so it is not suitable to apply fertilizer, but can be watered properly according to the dry and wet degree of the substrate. In the process of cultivation, there were almost no diseases and insect pests.
Hydroponic Culture method of Brown Bamboo

2: the plant shape of pocket coconut is the most beautiful when it is 30cm to 50cm. When the plant is too high, it will reduce the ornamental value because of the baldness in the lower part. Small plants can be cultivated below when planting.
Acquisition of hydroponic materials
The method of potted root washing was used. New roots can grow in a few days after washing.
Hydroponic culture method of cactus
We know that the cactus is favored by people because of its unique drought tolerance and beautiful appearance, but the cactus is dirty and difficult to manage because of its traditional cultivation methods. more people make beloved plants die because of poor fertilizer and water management. Now the cultivation of cactus has entered a new stage of hydroponics.
1: choose the female parent
First of all, we should choose the cactus with a strong sphere, and the key is to select the plant with the lower rhizome protruding downward. The cactus grafted with Mitsubishi sword is easier to be hydroponically cultured.
2: processin
After selecting the female parent, the original dead root under the sphere is completely cut off, and the cut mouth is required to be flat. Then rinse the soil attached to the rhizome with clean water and dry it in a dry place for 3 days to make the incision completely dry.
3: hydroponics
Prepare a glass bottle of the right size, or process it with a mineral water bottle, fix the flower mud of the cactus or foam at the mouth of the bottle, and add the nutrient solution, which is just high enough to touch the rhizome. In production, we recommend making a glass sink with a length of 60-100cm and a width of 20cm (transparent utensils can easily observe the contact surface between the liquid surface and the rhizome), prepare foam puzzles for children or foam boards for white buildings, and dig several triangular holes with sharp knives on the layout (the golden tiger can be fixed by cutting the mouth of the waste pure water bottle upside down. Note: cut off the mouth of the bottle so that the root of the golden tiger can be exposed from the cut mouth and then placed in a flat body with nutrient solution.) insert the Mitsubishi sword into the triangle hole, when the roots of all Mitsubishi swords are in contact with the liquid surface.
four. Post-treatment of hydroponics
Buy two magnets with a diameter of 6-10cm and put them into utensils in order to magnetize the nutrient solution and speed up the formation of aquatic roots. (you can also buy a small suction wall submersible pump for ecological fish tank from the market, which can be adsorbed on the inner wall of the nutrient solution and electrified to realize the flow and oxygen circulation of the nutrient solution.
5: the key points of water training.
The planted cactus is placed in an environment with strong scattered light, and the temperature is kept above 20 degrees Celsius. Change the nutrient solution immediately after the emergence of water rooting.
Note:
It is forbidden to spray water on the cactus in the process of mutagenesis, which can easily lead to the decay and necrosis of the sphere.
What should the family hydroponic magnolia pay attention to?
Hydroponic cultivation of Junzi orchid is a hygienic and simple cultivation method, which should be paid attention to in family cultivation.
① container selection. There should be no holes in the bottom of the cultivation container, and it is better to choose a transparent one, so that you can see not only the leaves and flowers, but also the roots. Glass bottles can be used; non-toxic plastic bottles or ceramic containers can also be used. The size of the container depends on the plant size, and the caliber should not be too large.
The solution cultivated by ②. It can be nutrient solution or clear water, but foliar fertilization should be paid attention to when cultured in clear water to supply the nutrients needed for the growth of Cymbidium.
③ change the liquid. Hydroponic Magnolia needs to change liquid regularly, the number of liquid change depends on the weather conditions, when the temperature is low, it can be changed about once a month; when the temperature is high, it can be changed once every 10 days, pay attention to wash the cultivation container when changing liquid.
How to scientifically cultivate Zhu Dinghong in water
In early winter, choose one or more red balls that have flowered or not flowered, cut off all the roots and leaves, peel off the dark brown skin, reveal white and green, and soak in clean water. After about 48 hours, take out the ball, wash off the paste of the incision with clean water, dry and put it into the flower organ. Flower utensils can be bowls, pots or daffodils, etc., put into washed pebbles, perlite, absorbent rocks, etc., and then put on the treated Zhu Dinghong bulb. Then pour in clear water, preferably clear spring water (if tap water is used, it must be placed for a few days). The depth of the water should be about 1 cm lower than that of cushions such as pebbles or flower utensils. The leaves and roots began to grow after about 10 ℃ at room temperature. The water in the basin should always be kept at the original water level. When the leaf grows to 2-3 cm, it is necessary to replenish fertilizer in time, and add 1% urea solution or 0.03% potassium dihydrogen phosphate solution or other compound fertilizer solution containing nitrogen, phosphorus and potassium every 10-20 days. At the end of the next spring, the bulbs with roots were planted in flowerpots for routine maintenance. In this way, the hydroponic bulbs bloom a little later than other conventional potted plants, just in time for the summer blooming period.
Technical management of hydroponics
1. What is hydroponics? Answer: hydroponic culture, also known as soilless cultivation or nutrient solution cultivation, is an agricultural production technology that uses nutrient solution and its supporting facilities to cultivate crops without soil. In order to fix the plant and increase the air content, most hydroponic plants use inert sand, gravel, peat and perlite as solid matrix, so it is also called sand culture, gravel culture, peat culture and so on. Since the history of human cultivation, crops have been planted on the soil, so the word agriculture in English is an Agrculfure synthesized by Agr and Culture. In 1699, British scientist Woodward used three different kinds of water, namely, Rain Water, river and garden soil leachate, to grow peppermint. As a result, the mint planted with garden soil extract grew the fastest. Therefore, it is concluded that "the growth of plants is determined by some substances in the soil". Unfortunately, due to technical limitations at that time, Woodward did not conduct further research. Until 1859 Mel-1865, German scientists Satchis and Knopp carried out the first accurate experiment of soilless cultivation and succeeded in cultivating plants with artificial nutrient solution made of inorganic salts. They called this method hydroponic culture. Sargis and Knopp are therefore recognized as the founders of soilless cultivation technology.
◆ 2. What are hydroponic flowers? A: hydroponic flowers are flowers grown using soilless cultivation techniques. Hydroponic flowers are divided into hydroponic flowers with media and hydroponic flowers without media. Hydroponic culture with medium is the sand culture and gravel culture mentioned above; media-free hydroponic flowers are divided into direct hydroponic flowers, floating hydroponic flowers, planting basket hydroponic flowers, atomized hydroponic flowers, drip irrigation under nutrient film and other cultivation forms. Each cultivation form has its own advantages and disadvantages, but if it is only measured in terms of beauty and home cultivation applicability, direct hydroponics is the most fashionable, beautiful and simple, so the hydroponic plants sold on the market are generally direct hydroponics.
◆ 3. Why is nutrient solution the key to the success of hydroponic flower culture? Answer: we all know that soilless cultivation is a very simple and mature technology when using inert substrate as a medium in a greenhouse environment, because there are computers to timely control humidity, temperature, light intensity, nutrient injection time, and so on, as well as specialized technicians to test the PH of nutrient solution and the balance of various elements with acidity meters and conductometers, which are difficult to achieve when used in a home environment. First of all, if the hydroponic flowers placed in the home are still cultivated in the matrix, there is no difference in aesthetics with soil cultivation, so the hydroponic flowers in the home should be soilless cultivation without medium. in the case of no medium, the plant is easy to have rotten roots and stink; this requires that the nutrient solution must be able to make the plant not rotten root, smell, smell and grow normally. In addition, household hygiene needs, which requires that the nutrient solution is not easy to breed mosquitoes and is non-toxic. In addition, the light at home can not be adjusted at any time like a solar greenhouse, which requires that the nutrient solution should be able to reduce the threshold of plant photosynthesis, so that it can grow well in the office and home environment. What's more, it is impossible to require every user to have special botanical knowledge like a botanist, so the nutrient solution must be easy to use and easy to operate, and everyone will learn it. Therefore, hydroponic flowers suitable for home cultivation have higher technical requirements for nutrient solution. Since mankind mastered the technology of soilless cultivation, scientists have successfully studied no less than tens of thousands of nutrient solution formulations, but it is very rare for nutrient solution formulations to meet the above requirements at the same time. Moreover, because of commercial interests, major flower companies regard their own nutrient solution technology as the first secret technology, so the nutrient solution formula that can be obtained from public data is only a theoretical or experimental formulation. can only be used as a reference material and can not be used in production activities. As a matter of fact, whether a nutrient solution is suitable for use in a household environment, as long as you try it, you only need to see whether the plant it shows is growing vigorously and with or without water roots, because it is still the same saying: "practice is the only criterion for testing truth!"
◆ 4. How can hydroponic flowers survive the winter safely? Answer: general flowers dormant when below 5-8 degrees Celsius, and tissue necrosis occurs when below 0 degrees Celsius. Therefore, if the indoor temperature is above 5 degrees Celsius, hydroponic flowers can generally survive the winter safely; in winter in the south, the indoor temperature is generally not lower than 5 degrees Celsius, if the extremely low temperature weather occurs for a few days, it can be solved by lighting a 60-watt incandescent lamp above the flowers to solve the problem; while in the north, because there is mostly indoor heating, it can also meet the safety of hydroponic flowers to survive the winter.
◆ 5. Can hydroponic flowers only cultivate some specific flowers? A: in modern greenhouses, generally speaking, our common popular flowers can be hydroponically cultivated. But in the home environment, because some specific conditions can not be met, so at present can only cultivate some semi-shady and shady flowers, in the balcony home suitable varieties are more.
◆ 6. Can ornamental fish grow normally in hydroponic flowers? How to deal with the change of water and normal feeding? A: because the "hydroponic Flower King" nutrient solution is completely non-toxic and rich in all kinds of minerals, fish can grow well in it. Each of our specialty stores has a model for raising fish in hydroponic flowers, just to tell guests this information. Generally speaking, the volume of more than one liter of hydroponic flowers is suitable for fish culture, and because the volume is limited, there should be a choice in the species of fish. Should choose some more adaptable fish species, such as goldfish, Xiao Jinli, etc., some aggressive or destructive fish should not be raised in hydroponic flowers, because it will harm plant roots; and some delicate fish are not suitable, because raising in a special aquarium is difficult to succeed, not to mention in a small vase with relatively poor conditions. The change of water can be carried out at the same time as the normal change of water for flowers, and it is the same as we usually raise fish in the fish tank, and there is no difference. As the special substances in the "hydroponic Flower King" nutrient solution can improve the oxygen solubility of water to facilitate the respiration of plant roots, fish generally do not lack oxygen in the nutrient solution, so there is no need to install oxygenation equipment on non-particularly hot days.
◆ 7. What are the water requirements for hydroponic flower dilution? Answer: the nutrient solution of Shuipaihuawang is highly concentrated and must be diluted before it can be used; when diluted, tap water can fully meet the requirements, and there is no need to use barreled water or pure water. If well water or river water is used, water quality tests should be carried out to understand the mineral content in the water. If the mineral content in the water exceeds the standard, the formula of the nutrient solution should be adjusted to facilitate the normal growth of plants. In the process of dilution, tap water can be directly used to dilute the nutrient solution without waiting for the chlorine in the water to volatilize, because the unique formula of the king of hydroponics will make the chlorine in the tap water volatilize quickly. however, if the difference between water temperature and room temperature is too big, it is necessary to let the diluted nutrient solution sit indoors for a period of time to prevent plant root hair damage caused by sudden changes in temperature, causing plant wilting.
◆ 8. What is planting basket hydroponics? Answer: planting basket hydroponic culture is a kind of hydroponic cultivation method based on the hydrotaxis principle of plant roots. The principle of hydrotaxis is that the root tip of a plant always grows in the direction of sufficient water, which is shown in that when the topsoil of a plant is short of water, in order to protect itself, its root tip will grow into a deeper soil. In order to absorb the water needed for plant growth and development and adapt to natural changes, the root growth has a very obvious direction: plants growing in swamps or water will not lack water, so the root growth is more chaotic. There is no obvious direction. So if you put a potted plant on the mouth of a wide-mouth glass bottle filled with water, the bottom does not need to be in direct contact with water, and the interval is about 1cm. The bonsai is not watered and only sprays a small amount of water. After about a week or so, the root at the bottom of the bonsai will grow into the water. At this time, you do not need to add water to make its roots grow longer and longer as the water level drops. If you use some fast-growing plants to do experiments, the effect will be more obvious. Similarly, you take off the bonsai that is already full of roots in the water and fix the plant with a planting basket, and decorate it with stones or decorations to become a pot of hydroponic flowers. The difference is that because there is no soil, you have to change the water into a nutrient solution. It's as simple as that.
◆ 9. Why do hydroponic flowers change water? Answer: because plants absorb water and inorganic salts from the nutrient solution, the nutrients in the nutrient solution will become less and less, and because of root respiration and metabolism, there will be more and more harmful substances in the water. So hydroponic flowers should be replaced with a new nutrient solution after a period of growth. In fact, this and soil cultivation of flowers is the same reason, soil cultivation of flowers to fertilize and change the soil once a year is also the reason. Hydroponic flowers in the vigorous growth of spring and summer water change time interval is shorter, slow growth in autumn and winter can be longer.
◆ 10. Why do hydroponic flowers sometimes become weaker and weaker or grow less exuberant? Answer: it is possible that the time interval of changing liquid is too long, the proportion of nutrient solution is not right (too light or too thick) or the light is too weak. If you rule out these factors, it depends on whether the high water level of nutrient solution makes the plant roots unable to breathe normally and cause hypoxia; if these are not, then we suggest that you had better consult the franchise store of Shuihua King.
The Disclosure of hydroponic Flower Market-- distinguishing true and false hydroponic flowers
At present, many companies have joined hydroponic flower shops, and there is an uproar all over the country, especially a company franchise store in Beijing will spread all over the country. As a researcher, I did not want to express my point of view. however, in order to maintain the healthy development of hydroponic flowers in our country, I have to complain about everything. Because the scam will not only damage the interests of consumers, but also cast a shadow on the hydroponic industry. at present, it is the low temperature season, and the respiration of plants is weak. After washing their roots, plants can be soaked in water for a period of time. Drowning-tolerant plants, such as Araceae, can be raised in water for 1-2 months, but as soon as the weather becomes hot and the physiological respiration of plants is strong, there will be hypoxia and rotting roots immediately. It is only one of the epiphyllum to buy dozens or hundreds of hydroponic works, which not only harms the interests of consumers, but also greatly affects the development of hydroponic industry. Now it reveals the "deception" from a scientific point of view.
1. The plants sold in the franchise store are basically Araceae plants. In winter, the growth rate of these plants slows down and their respiration becomes weaker. In addition, Araceae plants have a close relationship with aquatic plants and have strong drowning tolerance. Directly soaked in water after root washing, there is no uncomfortable reaction on the plant for a while, but it is impossible for it to thrive in water. It can only maintain the balance of water metabolism. The absorption of nutrients and respiratory function are seriously hindered, as soon as the weather becomes hot, the roots will be anoxic, stink and rot. Other terrestrial plants cannot achieve this method at all, so this is the main reason why they can only engage in Araceae plants to "deceive" at present. Their so-called mutagenic solution. I think it's better and more practical to call it "decoy". It is impossible for plants to change their tissue structure in a few minutes.
2. The high franchise fee charged by franchise sales is itself a kind of commercial hype, and if the goods are genuine, and if the technology is unique, it can also be said to be able to dominate the market truly has the significance of joining, and now this kind of joining can be said to be a fraud of money. one of its technologies has no scientific and technological content, that is, washing its roots and soaking in water, even fools can be concocted at a glance, and falsely, some training fees amount to 18800 yuan. Second, after decades of development, hydroponic technology itself is no longer a unique technology of a certain company, and it is impossible to monopolize the market by joining. Other hydroponic flower shops can also operate, and the funds are better and the technology is better than that of franchisees. Turning off the franchise fee is tantamount to being wasted. The real hydroponic flowers are not suitable for long-distance transport. in fact, what they are selling now are all the products after washing the roots of soil-grown seedlings, so it may be more accurate to say that pure-root flowers.
3. Hint: Araceae plants can be soaked in water for a period of time after root washing in late autumn, winter and early spring. We might as well give it a try. There is no need for decoy solution at all.
I have studied hydroponics for many years, and foreign countries have also investigated several countries with more developed hydroponics technology. It can be said that there are a large number of fraudsters in this kind of hydroponics market in China. But in the end, these joining scams will be cleared out by history and science. Remind everyone to polish your eyes and not to be induced by the decoy.
How to distinguish between true and false hydroponic flowers
True and false hydroponic flowers are actually the difference between induced flowers and non-induced flowers. at present, many hydroponic flower operators do not understand hydroponic flowers from a scientific point of view, but only from the perspective of commercial hype and personal profits. sell some conventional soil plants as hydroponic plants to fool consumers, resulting in a very bad social impact. After some citizens bought it at a high price, they died because of the physiological discomfort of the plants, which seriously hindered the healthy development of the hydroponic flower industry. In view of this problem, buyers can distinguish between true and false from the following aspects, in order to prevent being fooled.
A. look at the root morphology to distinguish between true and false: the induced hydroponic flowers usually exist in the form of whisker-shaped adventitious roots, unlike the roots in the soil, there are main roots, lateral roots, capillaries and root hairs, that is, they do not exist in the state of secondary roots of multi-stage branches. even if there are grades, they are based on a small number of bifurcated roots on the basis of fibrous adventitious roots. In addition, the number of primary adventitious roots of some original radicle plants increased significantly after induction, that is, the proportion of roots increased greatly, and the number of roots was large and developed, like a beard.
B, look at the color of the root system to distinguish between true and false: most of the aquatic roots of plants induced by aquatic plants have the characteristics of white, brittle and tender, even for some varieties that show natural roots, the color of aquatic roots is obviously lighter than that of terrestrial roots, such as yellowish white, light yellow, light brown and so on. This is related to the well-developed parenchyma of aquatic roots and no or less cork-like Lignification of cell wall thickening.
C, to distinguish between true and false from the integrity of roots: the aquatic-induced roots are re-grown and differentiated from the primary adventitious roots, and they are all completed in the water environment, with root integrity, while some soil-cultivated plants, although carefully washed, there are always slight damage or serious residual roots, which is difficult for soil-washed seedlings to achieve.
D, distinguish between true and false from the clarity of water: fake hydroponic works made by soil-washing seedlings, because the roots fail to form the adaptability of water, in an anaerobic environment, a large number of toxic intermediate metabolites will be discharged because of anaerobic respiration, so that the water in the container will quickly become mixed or deteriorated, and the turbid and opaque feeling shown by visual observation, that is, the water quality deteriorates or stinks, and the roots rot until the seedlings die.
E, the leaf angle is also true or false: especially for many herbaceous flowers which are very sensitive to ethylene, the leaf planting angle of many herbaceous flowers which are very sensitive to ethylene is obviously more flat than that of soil-washed seedlings, that is, the upper growth leads to the increase of the angle, even sagging.
Increase the content of dissolved oxygen in hydroponic nutrient solution
Except that the requirements of environmental factors such as light, temperature and humidity of hydroponic flowers are exactly the same as those of soil cultivation, the requirements of water, fertilizer and oxygen are very different in management-water: domestic hydroponic flowers should use soft water as water source. tap water in line with national standards can be used generally. Tap water after filtration, precipitation, sterilization treatment, clean and hygienic, pH below 7, can be safely used to cultivate hydroponic flowers. River water, lake water, pond water and well water are polluted to varying degrees, and the nutrients are serious, and all kinds of ions may vary greatly. if the content of one of these ions exceeds the standard, plants will be damaged or poisoned for a long time, so it is not suitable to be used as a water source for hydroponic flowers. Fertilizer: domestic hydroponic flowers must use low concentration special nutrient solution based on nitrate fertilizer. Hydroponic flower nutrient solution generally contains all the necessary nutrient elements for flower growth, the proportion of various elements is balanced, and the inorganic salt is in an ionic state, which is suitable for different flower varieties and their nutrient needs at different growth and development stages. And non-toxic, harmless, appropriate pH, conducive to nutrition absorption. It is not advisable to crush soil fertilizer and granular fertilizer for hydroponic flowers. Short-term use may have no obvious effect on flowers, if long-term application will inevitably hinder the normal physiological metabolism. What's more, organic fertilizer is not allowed to be used as the fertilizer source of hydroponic flowers. The diluted urine can be used for foliar spraying and should never be added to the nutrient solution. Oxygen: domestic hydroponic flowers, water (nutrient solution) is in a static state, dissolved oxygen is lower than / ppm/L, flowers barely maintain life in anoxic vessels, it is common for their roots to reverse growth and extend to the liquid surface in order to breathe more oxygen. Therefore, increasing the oxygen content of hydroponic nutrient solution is very necessary for the normal growth of flowers, especially in summer. There are several simple and easy ways to increase dissolved oxygen: 1. Increase the number of times to change the nutrient solution 2. Vibrate and increase oxygen, fix the flower plant in one hand, and gently shake the vessel in the other for more than 10 times. After shaking, the dissolved oxygen content of the nutrient solution can be increased by about 30%. 3. Add an appropriate amount of "solid oxygen" to the nutrient solution or 1% hydrogen peroxide (3% hydrogen peroxide). 4. Using miniature submersible pump or aeration pump (all standard products of aquarium) to carry out waterfall gas to the nutrient solution, plant roots can obtain sufficient oxygen in such an environment, the respiration is very exuberant, and promote the healthy growth of flowers.
Discern the false technology of hydroponic flowers at a glance
Hydroponic flowers, the combination of dynamic and static co-culture of flower and fish is its first intuitive impression. The earlier concept in China first sprouted at the beginning of the 21st century. (although some people planted some hydroponic plants such as Araceae and rich bamboos in water at the earliest, but this concept does not belong to the popular concept of "hydroponic flowers". Rising in 2003, many enterprises with market vision devoted themselves to the preliminary research and planning work in this industry, and in the case of the broadcast of "hydroponic Flowers" on CCTV 7 and 2 programs, hydroponic flowers flourished from 2004 to 2005. Hydroponic flowers have blossomed all over the country, providing technical learning and training, base production, and joining flower shops. Many false enterprises and individuals of hydroponic flower companies put on a show in the market under the stimulation of profits. on the one hand, it has contributed to the hype of the concept of hydroponic flower market in China. let a lot of citizens understand and understand this new concept and product. On the other hand, many investors and operators have become victims of this batch of market trends. As for 2006, those who have their own technological core and production capacity, and relatively strong economic strength and management ability, can still survive in such a chaotic market trend, there are very few who can survive. However, hydroponic flowers, a fashionable flower product, represents a new trend in the development of the flower industry. Driven by the economic interests of the market economy, there are still a small number of speculators in the market!
The author has been on this trip for three or four years and is more familiar with this industry. in view of the current mixed market of hydroponic flowers and plants, this article makes a systematic analysis and summary for the broad masses of people who love hydroponic flowers. and investors who are interested in joining the hydroponic flower industry to give a preliminary and comprehensive understanding for your reference:
Second, what is the real hydroponic flowers?
From a sensory point of view, the use of different types of glass vases, above the plant flowers (at present, the scope of hydroponic technology has been extended to other woody, vines, succulent plants, etc.), below to raise a few lovely small fish, that is, hydroponic flowers (plants)! But from the technical level, the real hydroponic flowers refer to the aquatic roots that change the physiological characteristics of their roots through a variety of biological, physical, computer and other technical means, and have plant ventilated tissue structure. and can adapt to water cultivation for a long time, can become a real hydroponic flower (plant)!
Third, how to identify real hydroponic flowers?
Judging from the sense: the present situation of hydroponic flower technology report 1, introduction: for a successful hydroponic plant, the root system of a successful hydroponic plant should be white, elegant and with more whiskers, which is very different from that of soil-cultivated plants. Soil-cultivated plant roots are dark black! (except for a few plant root color has a unique color, such as safflower after wood induction, from its root to its branches, the stem segments are all crimson! There are also some plants whose roots are nearly white after they are removed from the soil.
In addition, if the growth condition of the plant is not very robust and the leaves are drooping, it means that it has just been planted on the bottle and deceived the user to put it on! Even if it is induced, it cannot be sold as a commodity!
Technically, to judge:
Technically, to judge:
1) whether there is a professional technical level
If, as some businessmen say, all you need is the so-called "induction solution", "domestication solution" and "nutrient solution" to soak plants in water for a few days or hours, or some even say that hydroponic flowers can be cultivated in only tens of minutes or a few minutes, this can only be said by those who do not understand biotechnology, and those who understand biological principles all know that if there is a serious lack of oxygen in the water in the plant roots, the roots will soon breathe without oxygen and thus ferment. Rotten roots, so there are a lot of fermentation in the bottle, long mosquitoes, insects, turbid water is not clean and so on, the plant will soon die! Hydroponic flowers can be called hydroponic flowers only when they really induce the aquatic roots of plants and form hydroponic plants with aerated tissue and can adapt to the state of hypoxia in water. And the cultivation of aquatic roots can not be completed and realized by nutrient solution, it needs to integrate biological, physical, computer and other methods, after a long time of training, completely adapt to the water environment, in order to become a professional real hydroponic flowers!
2) do you have a strong level and ability of artistic combination?
Hydroponic flowers belong to medium-and high-grade consumption, and its ornamental value lies in the combination of artistic sense, each product lies in its artistic glass bottle container, beautiful plant shape, white and elegant root system, and the perfect combination of fish and water plants and other ornaments in the bottle! Is not a professional hydroponic flower works, in addition to the natural senses, a strong artistic combination can not be formed by the general beginner! From this technical level, we can tell at a glance whether manufacturers have such an aesthetic level!
3) whether there are facilities and fixed supply channels for the production of hydroponic flowers?
Whether there are facilities for the production of hydroponic flowers can also be seen whether businesses have the ability to produce hydroponic flowers, if there are neither fixed production facilities nor manufacturers with strength and brands as sources of supply, then such hydroponic flower providers are likely to be "hydroponic flowers" made by washing the roots of soil-grown plants!
To examine in terms of variety:
The hydroponic flower varieties that real professional hydroponic flower manufacturers can produce are not only those plants such as Araceae and crassulaceae, such as dripping Guanyin, Chunyu, Fugui bamboo, tortoise back bamboo, evergreen and other plants that are easy to raise in water. These plant varieties, themselves close to water, hydrophilic, the general method can be cultivated in water, professional producers should be all kinds of woody plants, all kinds of water-resistant plants. Such as iron tree, cactus, rich tree, flutong, and even such as yew, sweet-scented osmanthus, fruit trees can achieve hydroponic culture of plants! If the business can provide a single variety of plants, it must not belong to professional hydroponic flower manufacturers!
In terms of time:
Time is the final only criterion for testing hydroponic flowers. If they cannot adapt to hydroponic cultivation for a long time, they will die within a few days if they are only a flash in the pan. Many of these are hydroponic flowers that can be produced in a few hours after those speculators wash away their soil roots. In a few days, the flowers bloom and bloom. Therefore, for now, for those owners who cannot provide the shelf life of the goods, most of them are speculators, such as those who cannot provide the shelf life of the goods, it is recommended not to buy them, so as not to be fooled! Fourth, how to identify a real professional hydroponic flower manufacturer?
Driven by interests, many market speculators, in publicity, adopt various "formal" means of information transmission to fool the majority of consumers and investors, in order to make some of the real hydroponic flower technology, no base, no scale. Some without technical personnel are in scientific research institutes in national universities (such as Wuhan University, Beijing University of Science and Technology, Tsinghua University, Huazhong Agricultural University, China Agricultural University, Beijing Forestry University, etc.) (such as Chinese Academy of Agricultural Sciences, Chinese Academy of Sciences, Chinese Academy of Forestry Sciences, etc.) A scientific research center, etc.) several offices are rented in the institutions under the Ministry of Agriculture (such as the veteran cadre Bureau of the Ministry of Agriculture, a technology center of the Ministry of Agriculture) or in the office building The so-called high-tech bag companies that began to advertise to make money and the technology transfer "guerrilla" companies with one shot to another have no foothold. It also makes it malicious to transfer some immature so-called "hydroponic flower technology" at a low price to lose the deceptive market, but also for you to learn these real technologies.
The author solemnly reminds: no matter you see similar technology or similar advertisements in any place or any media in the country, you must keep your eyes open, how open-minded you are, how many restaurants you see, and how much you compare. You must carefully compare the unit size, technical strength, personnel quality, product quality and after-sales service. {{remember: you must take a look at their florist products, and then ask them to call the franchisee, and try to go to the franchisee to have a look. To determine the authenticity of the technology, you may not provide it to you in many places, so you should think twice before you act. This is the most direct and final judgment, except of course. Those "high-level" companies will also use "medical care", "school care", "room care" and "wine care" to ignore you at the level of Zhao Benshan, which makes it impossible for you to guard against! You must carefully check the authenticity of the technology, training capabilities, and relevant documents; you must not be deceived by these so-called high-tech companies, which will bring unnecessary losses to your economy and spirit. In addition to distinguishing whether hydroponic flowers are real or not from the product approach, in fact, we can only pay more attention to see through many speculators one by one. Here are some experiences on how to fertilize hydroponic flowers outside their roots.
Static hydroponic cultivation of flowers is a cultivation method under the condition of anoxic root system, which will cause some defects to the normal development of flowers. In order to improve the quality of flowers, foliar fertilization can be used to supplement nutrient elements. During the vegetative growth period of flowers, 0.2% potassium nitrate dilution can be used to spray foliar.
Should use fine hole spray pot, try not to make fertilizer liquid loss, the back of the leaf should also be sprayed, spray once a week, spray twice during the growing period, can make hydroponic flowers flourish. Flowers suitable for leaf viewing and flower appreciation at the same time, such as taro, begonia, bamboo begonia, calla, etc., can be sprayed on the leaves once a week with 0.15% potassium dihydrogen phosphate diluent during the budding period until the flowers bloom.

How does Anthurium andraeanum leaves become brown and necrotic?
Two possible causes of browning and necrosis of Anthurium andraeanum seedlings can not be ruled out: one is bacteria | Leaf spot, which appears waterlogged irregular brown to dark brown spots between leaf veins at the initial stage of infection, surrounded by yellow halo circles, and in severe cases, the disease spots merge into large spots, wilting and curling hanging on the short stem.

What is the reason why Anthurium does not blossom?
Anthurium andraeanum generally refers to large and small leaf candles. The main reason for not blooming for 3 years is that there is no maintenance and management according to its ecological habits. It is native to the rainforests of Colombia and likes the conditions of warmth, high humidity and scattered light. The optimum temperature for growth and flowering is 22-30 ℃, and the temperature is best kept relatively constant.
