What to do if the leaves of Zizhu plum turn yellow, supplement light / increase water and fertilizer application / cut root weight planting

Purple bamboo plum, a highly effective plant, not only grows good-looking, but also purifies the air and beautifies the home, but also has a good use in medicine. Such a plant, naturally raised by many people at home, but in the breeding process, a little careless, it will appear the phenomenon of yellow leaves. So, what if the leaves of purple bamboo and plum turn yellow? Today, the editor is here to solve this problem for everyone.

First, the leaves of purple bamboo and plum turn yellow, look for the cause

As a beautiful potted plant, the breeding method of purple bamboo plum is not difficult, but there are many novice, they do not have a system to raise, the result will be a problem. In view of the yellowing of purple bamboo plum leaves, the editor sorted out five causes and treatment methods for the yellowing of purple bamboo plum leaves. Let's move on.

Second, the causes of yellowing of purple bamboo plum leaves and its solutions.

1. Environmental mutation

There are actually many reasons for the yellowing of purple bamboo and plum leaves, but the first thing we should consider is the environment. Nowadays, many flower friends buy purple bamboo plum online, which can easily lead to a large geographical span, the environment changes too much, purple bamboo plum temporarily can not adapt, and there are leaf yellow symptoms.

Solution: it is very simple to ask the seller about the growth environment before Zizhumei, and then we change the environment at home until Zizhumei is fully adapted. After normal maintenance for a period of time, the leaves of purple bamboo plum will be restored.

2. Lack of light

Zizhu plum Xiguang, in addition to summer noon need proper shading, the rest of the time need to give it sufficient light. If the purple bamboo plum is placed in a dark place for a long time, resulting in insufficient light, it is easy to cause the leaves to turn yellow and dry.

Solution: if it is lack of light, it is very simple, just supplement the light. In this regard, the editor suggested that flower friends can move purple bamboo plum potted plants to places with plenty of light, such as balconies and sunny windowsills.

3. Fertilization is too little.

The growth of purple bamboo plum is inseparable from adequate nutrients, once the fertilization is too little, resulting in the lack of nutrients, it will also cause purple bamboo plum leaves to turn yellow.

Solution: flower friends can replenish fertilizer in time, of course, the amount should be controlled, because if you apply too much fertilizer, it will also cause leaves to turn yellow. In this regard, the editor suggested that flower friends can give purple bamboo plum 1-2 times a month to apply organic fertilizer, such as bean cake, oil cake fertilizer and water.

4. Lack of moisture

Purple bamboo plum likes a humid environment. If it is underwatered or has not been watered thoroughly for a long time, the plant will turn yellow because of lack of water.

Solution: if purple lack of moisture causes purple bamboo plum leaves to turn yellow, flower friends can replenish water in time and spray around purple bamboo plum potted plants through sprinklers. However, do not water too much, otherwise it will be counterproductive, generally speaking, we should follow the principle of "do not dry, do not water, water thoroughly".

4. Rotten root

Although ① likes the humid environment, it can not be watered too much, because if there is too much water, it is easy to cause stagnant water in the basin, thus rotting the root system. ②, if the root of purple bamboo and plum is too long, it is also easy to rot. There is something wrong with the root, which can not absorb nutrients normally. In the long run, the leaves of Zizhumei will naturally turn yellow.

Solution: if the root rot caused the purple bamboo plum leaves to turn yellow, the flower friends should cut off the rotten roots in time, then disinfect them, and then change the soil and replant them.

Generally speaking, although purple bamboo plum is easy to raise, it will also have problems if we do not pay attention to it. However, after reading the full text, I believe you have a clear mind, the leaf yellow problem can be solved in accordance with the above method. With regard to the yellowing of purple bamboo plum leaves, the editor has introduced this, hoping to give you some help. Finally, may everyone's purple bamboo and plum blossom with beautiful flowers.

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.

(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 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

Due to the rising temperature, the water demand of potted ornamental plants will gradually increase. In addition to paying attention to the combination of root watering and foliar spraying, we must also pay attention to the quality of water used for watering and spraying, and it is best not to use tap water directly. In particular, do not directly use tap water treated with bleach. 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%. The main species of potted flowers suitable for acidic water quality are camellia, tea plum, plum blossom, rhododendron, Yingshanhong, gardenia, Ruixiang, magnolia, chrysanthemum, begonia, safflower oil tea, etc.; foliage species are: iron tree, spring feather, tortoise back bamboo, palm bamboo, rubber tree, fern, Luohan pine, variable leaf wood, red (green) gemstone, hulk, green emperor, synthetic fruit taro, bamboo taro, pineapple, Brazilian wood, rich tree, goose palm wood, etc. 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. For Chimonanthus praecox, when the pot-shaped fruit sac on the fruiting mother tree changes from green to yellow, and then from yellow to brown, the internal seeds are brown; peel off the fruit sacs in time, remove the seeds, soak them in cold water for 24 to 36 hours, wait for the seeds to absorb enough water to expand, and then bury them in clean wet sand to sprout. After about 2 weeks, the seeds can be split and sown in a ditch. 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 2x3, 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

Grafting: using potted wintersweet seedlings as rootstocks, grafting fine varieties of wintersweet; using potted purple magnolia and white magnolia seedlings as rootstocks to graft white peony, Michelia, etc. bud grafting, namely grafting and breeding fine rose varieties by taking wild rose seedlings as rootstocks; budding and breeding longevity peach, green peach, purple-leaf plum, red-leaf peach, dark plum, plum blossom, trifoliate plum and the like by taking apricot, peach, plum and the like one-year-old seedlings as rootstocks; grafting and breeding red maple, feather maple, red maple and the like by taking 1 - 2-year-old maple seedlings as rootstocks. Branching, using camellia oleifera, safflower oil tea or single-petal camellia seedlings as rootstocks, branching camellia oleifera and camellia oleifera; using purple butterfly and jade butterfly in hairy cuckoo as rootstocks, splitting or belly-grafting Belgian rhododendron or western rhododendron.

4. bead

In June, the feasible flower and tree species for layering propagation are: Rhododendron, honeysuckle, hydrangea, snowball flower, Qionghua, brocade flower, oleander, osmanthus, camellia, plum blossom, wintersweet, clove, gardenia, red maple, Milan, pearl orchid, jasmine, white peony, etc.

5. ramets

In June, the flower species that can be divided and propagated are: Nephropteris, Calla (after flowering), Bambusa, Aproachus, Evergreen, Bromeliads, Twelve Volumes, One-leaf Orchid, Chlorophytum, Acorus, Ophiophora japonica, etc.

II. Harvesting seeds and transplanting

1. Harvesting seeds

The feasible grass flower seeds harvested in June are: Dianthus chinensis, cornflower, snapdragon, dwarf snow wheel, high snow wheel, hollyhock, mallow, primrose, caltrop flower, amaryllis (with picking and sowing), etc.

Flowers and trees seeds that can be harvested in June: After the seeds of Chimonanthus praecox are harvested, if the nursery conditions do not allow, the seeds can also be dried and stored until the next spring before sowing, which will not affect the germination rate; Peach, apricot, etc. should be sown with picking, or the seeds should be stored in sand until the crack germinates before sowing; Osmanthus fragrans seeds harvested in June, washed after removing the fleshy pericarp, stored with wet sand, promote the post-ripening of seed embryos, and select the nursery for sowing when they germinate.

2. Transplanting and potting

In June, a considerable number of grass flowers need to be transplanted or potted, they are: evening primrose, drunken butterfly, balsam, guinea balsam, primrose, ornamental pepper, winter coral, red tobacco, petunia, marigold, peacock grass, zinnia, chilies, a string of red, dragon mouth flower, ground skin, sulfur chrysanthemum, cockscomb flower, 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 transplantation. However, for some small flower shrubs, such as star anise, broad-leaved mahonia, mahonia, hypericum, gardenia, privet, red leaf berberine, boxwood, under special circumstances, transplanting with the ball is not necessary, just as the old saying goes: "do not move at all times, do not call the tree to know", but after transplanting, water spraying and shading management should be strengthened.

III. Flower Management

1. watering

June potted flower watering should pay attention to the following aspects: First, watering time, 10 a.m. or 5 p.m. is good, generally watering once a day; Second, watering temperature, should keep irrigation water and pot soil temperature basically consistent, if the water temperature and soil temperature difference is too large, will cause potted flower roots and leaves to be stimulated and then affect their growth; Third, the combination of watering and spraying. In case of weather without rain for several days, in addition to watering the pot, spray water on the leaves and around the potted flowers to improve the humidity of local space. If it is cloudy continuously, decide whether to water and spray according to the dry and wet conditions of the pot soil.

A species of flower that enters semi-dormancy or dormancy in summer. Semi-dormant ones such as: Oxalis tinctoria, geranium, fuchsia, clivia, calla lily, begonia, etc., when the temperature reaches above 30℃, due to its weak growth activity and low metabolic level, it is necessary to reduce watering and keep the pot soil moist; deep dormant species such as: Cyclamen, Lycoris radiata (class), Ranunculus chinensis, Dutch peony, etc., in high temperature performance for the ground stem leaf withered, underground nutrition fibrous root withered, underground stem or root dormant in the soil over summer, it must stop watering, moved to a cool place, keep the pot soil not too dry can.

[page] If it rains continuously, check the potted plants comprehensively after the rain stops. If there is accumulated water in the pots, pour it out as soon as possible. After the pot soil is dried, loosen the soil to avoid rotting the roots of the plants; or knock down the potted plants before the heavy rain arrives. After the rain stops, straighten the potted plants.

2. fertilization

Flower Growers 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. The woody flower species suitable for cutting propagation in July are: red-backed cinnamon, southern bamboos, poinsettia, tiger prickly plum, hypericum, golden plum, sea immortal, eight immortal flowers, brocade, hemp leaf hydrangea, snow spray, Ruixiang, gardenia, fragrance, Tiannu, triangular plum, Milan, jasmine, pearl orchid, goose palm wood, ten great efforts, pomegranate, crape myrtle, hibiscus, fiery thorn, Zhu banana, mulberry, June snow, smile, coral tree, mulberry. 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.

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 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 species with long flowering period, such as rose, magnolia, jasmine, pearl orchid, crape myrtle, pomegranate, Milan, four seasons cinnamon, cinnamon, triangular plum, five-colored plum, etc., as well as daidai, bergamot, kumquat, lemon, rich seeds, firethorn, golden marbles, pomegranate, pumpkin, papaya, etc., in addition to ensuring nitrogen supply, we should also apply appropriate amount of available phosphate and potassium fertilizer, such as potassium dihydrogen phosphate and so on. 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. The ornamental plants that can be cut are: goose palm wood, golden peach leaf coral, bamboo begonia, gardenia, golden bracts, coral flowers, cinnamon, pearl orchid, plantain, jasmine, Guangdong evergreen, silver silk grass, camellia, camellia, Camellia, Michelia, etc., which should be moved indoors 5 to 6 hours before and after noon. 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. First, the difference between water temperature and soil temperature and air temperature is too big; second, we should pay attention to the time of watering and spraying, which can be carried out before 10:00 or after 4 p.m.; third, while watering, loosening the soil for potted plants should not be ignored. fourth, it is best to put a small amount of ferrous sulfate in irrigation water to meet the needs of most ornamental plants in acidic soil environment. If the balcony is more spacious, you can use bricks to build a simple sand pool with 10 cm thick wet sand, and then put some more humid potted flowers on the wet sand, such as: tortoise back bamboo, one-leaf orchid, cherry, camellia, tea plum, taro, spring orchid, Jianlan, pineapple, red (green) gemstone, magnolia, etc., usually spray water instead of watering, it is very beneficial to its safety over the summer. 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. Trim. Continue to prune the garden hedges and ball ornamental plants with strong growth and budding, which is also the last pruning of balls in the growing season in the northern region this year. The main species of courtyard hedges and color blocks suitable for pruning are: boxwood, French holly, spinulosa Photinia, privet, lobular privet, red leaf Berberis, gold leaf privet, Phnom Penh Platycladus orientalis and so on.

The ones that can be planted on the ground are: a string of red, thousand-day red, sulfur chrysanthemum, ground skin, marigold, peacock grass and so on. 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. For land-planted flowers and trees that blossom continuously or watch flowers and fruits in autumn, such as crape myrtle, rose, cinnamon, tangerine, pomegranate, leaf flower, hibiscus, chrysanthemum, canna, dahlia, plum, southern bamboo, firethorn, cinnabar root, kumquat, etc., as well as a large number of autumn grass flowers, it is appropriate to apply balanced available fertilizer of nitrogen, phosphorus and potassium. For the flowering kumquat, cinnamon, cinnamon and so on, fertilization can be stopped during the flowering period. 5. Pest control. The green thorn moth that harms flowers and trees such as crape myrtle, pyracantha and begonia can be sprayed with 1000 times liquid of trichlorfon crystal for control; for longicorn beetles that harm crape myrtle, papaya and begonia, poison labels can be inserted from the wormhole to control powdery mildew on rose and chrysanthemum plants. 50% carbendazim wettable powder 1000 times solution can be used at the initial stage of the disease. 6. Seed collection. The woody ornamental plants that can be collected are mainly flowers and trees of Magnoliaceae. Such as Tiannu, Michelia, Magnolia, Magnolia, Yunshan Magnolia, Lechang Michelia, Michelia mollissima, Michelia mollissima, Magnolia magnolia and so on. 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.

Feasible plant and flower species are: Bletilla striata, Jian Lan, Chunlan, Cymbidium, Hosta, Purple Calyx, Shegan, Iris, ornamental pineapple, Ophiopogon japonicus, auspicious grass, onion orchid, evergreen, one-leaf orchid, rooting and so on.

1. Gather seeds. The grass flower seeds that can be harvested in November are: a string of red, thousand-day red, hundred-day red, emerald chrysanthemum, peacock grass, marigold, maple sunflower and so on.

The species of flowers and trees that can be collected for dry storage in November are: black pine, Huangshan pine, five-needle pine, metasequoia, cypress, Japanese cypress, Japanese flat cypress, acacia, maple, Camptotheca acuminata, Eucommia ulmoides, red redwood, Sapium sebiferum, wisteria, crape myrtle, Caragana, hemp leaf hydrangea. The types of flowers and trees that can be sowed on pick or must be stored in wet sand are: privet, lobular privet, palm, camphor, pencil cypress, disease-free seed, Chinese wolfberry, yew, magnolia, holly, wolfberry, firethorn, heather, Chinese rose (used to cultivate rootstocks) and so on.

two。 Transplanting and planting. The species of grass flowers that can continue to plant and transplant flower beds in November are: short snow wheel, carnation, hollyhock, mallow, pansy, goldfish grass, daisy, calendula, kale and so on.

The species for transplanting big trees in November are: Cinnamomum camphora, Magnolia grandiflora, Albizia mandshurica, Sapium sebiferum, Ligustrum lucidum, Luan tree, tallow, white magnolia, sweet-scented osmanthus, red maple, red leaf plum, plum blossom, wax plum, seven-leaf tree, Linden tree, giant bauhinia, horse Liriodendron, two Qiao magnolia, papaya, begonia 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, golden bell, 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.

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.

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.

Conservation measures of southern plant Zizyphus jujuba

Part 1: "arrangement of plants in the South"

Egg flower

Egg flower, its flowers are really like eggs, the outside is milky white, the center is bright yellow, just like the egg white yolk, it looks really Q. Its branches are thick and succulent. The leaves are also big, and the flowers and leaves gather on the top of the branch. it blossoms brilliantly in summer, giving people a feeling of purity and elegant temperament, which is very suitable for people to watch carefully. After falling leaves, the bare trunk bends naturally and its shape is very beautiful. It is very suitable for planting in courtyards and grasslands. Egg blossoms like the environment with high temperature and humidity, plenty of sunshine and good drainage. It is strong in nature and can withstand drought, but it is afraid of cold and avoid waterlogging. It likes to grow in acidic soil, but it is also alkaline-resistant. It is better to cultivate acid sandy soil which is deep, fertile, permeable and rich in organic matter. The cuttage method was used for propagation. When growing egg blossoms, you should also pay attention to pest control, such as brown spots on leaves or even dark black leaves, which is because of egg flower corner spot, so you should pay attention to take measures at this time. Of course, there may be other diseases, so egg flower needs your care and care. In fact, egg flowers in addition to white, there are red and yellow, can extract essence for the manufacture of high-grade cosmetics, soap and food additives, the price is quite high, great commercial development potential; can also be dried flowers for tea, commonly known as egg scented tea, has the effect of curing fever and diarrhea, moistening the lungs and detoxifying. The egg flower has a beautiful tree shape, many branches, strange shapes and various shapes; the leaves are like loquat, and after falling in winter, the branches leave semicircular leaf marks, quite like antlers with beautiful spots, which can be described as the first choice for landscaping, courtyard layout and potted ornamental small trees in the tropics. The bark is thin and grayish green, rich in toxic white juice, which can be used for external application to treat scabies, redness and swelling.

Leaves papery, Obovate, broadly Obovate or Obovate, Obovate-elliptic, base overgrown branches and leaves elliptic. Magnolia is very much like a lotus flower. When it is in full bloom, the petals spread in all directions, making the courtyard blue and white, dazzling in white light, with high ornamental value. Coupled with the refreshing fragrance, it is actually an ideal flower pattern for beautifying the courtyard. Magnolia is light-loving, hardy and can survive the winter in the open field. Love dry, avoid low humidity, planting land waterlogging is easy to rot roots. The sandy soil, which is fertile, well drained and slightly acidic, can also grow on weakly alkaline soil. In the south with higher temperatures, it can blossom from December to January of the following year. Magnolia has strong resistance to harmful gases. If the flower is planted in a factory polluted by sulfur dioxide and chlorine, it has a certain resistance and the ability to absorb sulfur. Artificial fumigation with sulfur dioxide can absorb more than 1.6 grams of sulfur in 1 kg of dried leaves. Therefore, Magnolia is a good anti-pollution greening tree species in air pollution areas. Magnolia likes light, young trees are more resistant to shade, not resistant to strong light and western sun, too strong light or western sun, it is easy to burn trees. Magnolia likes fertilizer, in addition to the application of base fertilizer when planting, it should be fertilized every year after that. Sufficient fertilizer can make the plant grow vigorously, the leaves are green and thick, not only have many buds, but also have large flowers, long flowering period and fragrant. Magnolia is a tree species with strong disease resistance. the main diseases are anthracnose, chlorosis and leaf burn.

Bamboo taro

Bamboo taro is an herb. Most varieties have underground rhizomes or tubers, leaves solitary, larger, ovate or ovate-lanceolate, veins pinnately arranged, distichous, entire. Amorphophallus is a good ground cover plant with various colors and a good foliage plant. Amorphophallus is a tropical plant that likes a warm, humid and brightly lit environment, is not cold-resistant, is not resistant to drought, and is afraid of hot sun exposure. If direct sunlight will burn the leaves, the edges of the leaves will be partially scorched, the new leaves will stop growing, and the leaves will turn yellow, so we should pay attention to shading. Bamboo taro is sensitive to water, so it should be fully watered during the growing period to keep the basin soil moist, but the soil should not accumulate water, otherwise it will lead to root rot and even plant death. Bamboo taro should be more "delicate". Enough care should be put into 365 days, and if there are major fluctuations in the environment in a few days, it will leave "evidence of guilt" on the plant, which is the consensus of taro seed dealers and producers. There are not many diseases and insect pests in bamboo taro family, such as shell insects, whitefly and so on. Of course, it has other values, such as medicinal value and dietary value. Bamboo taro powder is almost entirely starch, does not contain vitamins, and contains only 0.2% protein. It can be used as a thickener for soups, sauces, pudding and tails. Add water and boil to make a transparent, odorless, delicious paste. Compared with other starches, the fine quality of taro powder can be cooked at lower temperature and shorter time, and it is easy to digest. It is especially suitable for making egg products such as milk and egg paste that can not be overcooked. It is also suitable for making light, low-salt and low-protein food. Efficacy: clearing lung and relieving cough, clearing heat and diuresis. Main treatment: treatment of cough due to lung heat and acerbity in urination due to damp-heat of bladder

Liriodendron chinense is an evergreen plant with bright red new leaves. When different strains mature, the leaf color and flower color are different, and the leaf size is also different. In the garden application, it is mainly considered that the two factors of leaf color and leaf size bring leaf color contrast to form color contrast, and the florescence can also be staggered. Main insect pests: aphids, ulnar moths, yellow armyworm, Plutella xylostella, large and small ground tigers and beetles. Common diseases of Carthamus tinctorius: anthracnose, blight, mosaic disease. Anthracnose: it mainly harms the old leaves, basal leaves and leaves because they are red, and the disease spots are

Now black round spots, or nearly round, resulting in early defoliation, serious damage in the rainy season from July to August, the pathogen is actinomycetes. The pathogen overwintered with hyphae on diseased leaves, which was the initial source of disease in the following year. When you find that there is a disease in the branches and leaves of Carthamus tinctorius, you should treat it in time.

Green peach

Green peach is a variety of peach, tree, 3-8 m high; crown broad and spreading; bark dark reddish brown, rough when old is scaly; branchlets slender, glabrous, glossy, green, turning red toward the sun, with a large number of lenticels; winter buds conical, tip obtuse, outside pubescent, often 2-3 clusters, leaf buds in the middle, flower buds on both sides. Leaf blade oblong-lanceolate, elliptic-lanceolate or Obovate-lanceolate. Blue peach is sunny, drought-resistant and intolerant to wet environment. Like the warm climate, good cold resistance, can survive the winter safely in the natural environment of minus 25 degrees Celsius. The soil is required to be fertile and well drained. Do not like stagnant water, such as planting in low-lying areas of stagnant water, it is easy to die seedlings. The garden is worth green peach blossoms, beautiful and beautiful when they bloom, and the ornamental period is as long as 15 days. In landscaping, it is widely used in lakeside, streams, both sides of roads and parks, etc., in small-scale greening projects such as courtyard greening embellishment, private gardens, etc., as well as potted ornamental plants, and often used to cut flowers and make bonsai. It is also common to weave branches and green peaches. The landscaping of Bitao has a wide range of uses, and the greening effect is outstanding, and the planting year has a particularly good effect. Can be planted, piece planting, isolated planting, there was a very good green effect in that year. Green peach is one of the commonly used color seedlings in landscaping, which is usually used together with purple leaf plum, purple leaf dwarf cherry and other seedlings. Flowers and shrubs are planted to form a scene of a hundred flowers blooming. In addition to the ornamental value, there is also medicinal value. The gum secreted on the trunk of the peach tree, commonly known as peach gum, can be used as an adhesive. It is a kind of polysaccharide substance, which can be hydrolyzed to produce arabinose, galactose, xylose, rhamnose, glucuronic acid, etc., which is edible and medicinal, and has the effect of breaking blood, promoting blood and tonifying qi. Diseases often occur in summer and autumn. The main diseases are: White rust and brown rot, perforation, anthrax, gum disease, leaf shrinkage disease. The main pests are aphids, red spiders, shell insects, red-necked longicorn beetles and so on.

Part II: "maintenance Plan 4"

Maintenance and management scheme of landscaping

Maintenance and management is very important in landscaping, it is a long-term and repeated work, with comprehensive technical requirements, including the destruction of people and animals, sanitation and cleaning, pruning of flowers and trees, watering and fertilization, pest control, flower bed flower planting and so on. The completion of garden green space does not represent the completion of the garden landscape. People often say that "three minutes, seven minutes". Only with high-quality and high-level maintenance and management, the landscape can be gradually formed and perfect.

Characteristics of the present situation of plants in the cultivation park:

1. The greening covers an area of about 2.45419 billion square meters, and the green coverage rate is high. There are a large number of different specifications and varieties of trees and trimmed shrubs, and their initial growth has gradually taken shape. After our careful investigation, the characteristics of plant planting are roughly divided into two areas according to the original general plan:

1) Square area: the plant planting style in this area is relatively open, with ginkgo biloba, Zhengnan and large trees in the square.

Plant mainly, properly cooperate with low shrubs, the overall space is more transparent.

2) Factory area: the plant varieties in this area are complicated, worn by large and small trees, shrubs and ground cover plants.

Planted in front of the door with more valuable large plants (Canary jujube, blue flower, small leaf banyan pile head

The best sweet-scented osmanthus, etc. Whether it can still keep the office garden elegant, elegant and sparse?

The scenery, can also make the hotel villa courtyard to carry forward its delicate and gentle, leisurely and relaxing atmosphere

It all depends on the acquired maintenance.

two。 In the greening condition of the vertical area, we can find the following problems: the growth of ① shrubs is poor and the shape is monotonous; the potential of ② flowering shrubs is poor, and the flowering condition (including the number of flowers, flower size, color, secondary flowering) is not satisfactory; there are many weeds in ③ lawn, and there is a tendency of grass weeds in some areas; there is a situation of diseases and insect pests in ④.

1. We are prepared to take the following rectification measures:

1. Carry forward three-dimensional horticulture and shape hedges and shrubs. For flowering shrubs planted with embellishment, measures should be taken to promote their growth and shape according to the trend, which depends on the specific plant growth and plant shape. The hedges in the local area are highly regular, and the uniform strip undoubtedly makes the garden which should be free and leisurely mechanical and rigid. We can also try to trim it into a wavy shape, match it with the relaxed and leisure residential landscape, enliven the atmosphere of the whole garden and create a more fluent living environment.

2. Immediately start the prevention and control of diseases and insect pests. For plants with the characteristics of diseases and insect pests, large-scale chemical control should be carried out immediately.

3 、

4 、

5. Apply pesticides and increase the workload of manual pulling for lawn weeds. Different maintenance and management schemes were implemented for different plants (mainly fertilizer supply, base fertilizer, topdressing, foliar fertilizer, different plants have different fertilization methods and fertilizer choices in different seasons). Plants are listed. We classify all the plants, and then make a green sign to mark it.

All the plants in the area are listed for their families, genera, and living habits. This can be done.

Enrich the staff's plant knowledge, can also add to the cultural atmosphere of the park, and can be marked with eye-catching

Make greening get more attention.

6. greening and maintenance is not an overnight thing. While doing a good job in rectification and reform, we will also be right.

The same plants take different maintenance measures at different times, and we arrange our daily work month by month.

(the detailed rules are attached), in order to maximize the landscape effect in the blueprint.

We also ask Party A to put forward more suggestions to make our work perfect step by step.

7. Maintenance responsibility

During the contract maintenance period, our company organizes reasonably and carefully maintains according to the operation rules and quality standards of landscaping maintenance, and dispatches professional horticulturists to organize and arrange the management and protection work, and flexibly dispatch not less than experienced workers according to the weather and plant growth conditions of each season to complete the maintenance and management tasks in quality and quantity.

(2) the specific arrangements for the maintenance of gardens in one year:

January: the coldest month of the year, with open-field trees dormant.

1. Winter pruning: fully carry out the shaping and pruning of deciduous trees; pruning dead branches, disabled branches, disease and insect branches on large and small trees and branches that hinder overhead lines and buildings.

2. Inspection of street trees: check the situation of binding and piling of street trees in time, and rectify them immediately when they find that they are loose, lead wire embedded skin, shaking piles and so on.

3. Pest control: winter is a favorable season to eliminate garden pests. The pupae and cocoons of the diamondback moth can be dug up and burned to death in the loose soil under the tree. Scale insects begin to move in mid-January, but they move slowly at this time, so we can scrape off the larvae on the tree trunk. Pest control in winter often has twice the result with half the effort.

4. Green space conservation: green space, flower beds and other places should pay attention to picking out large weeds; lawns should pick grass and cut edges in time; attention should be paid to anti-freezing watering in green space.

February: the temperature is higher than the previous month, and the trees are still dormant.

1. The maintenance is basically the same as in January.

2. Pruning: continue pruning withered and diseased branches of large and small trees. Trim all kinds of trees before the end of the month.

3. Pest control: continue to control diamondback moth and scale insects.

March: the temperature continues to rise. after the middle of the year, trees begin to sprout and some trees (such as camellia) blossom in the last ten days.

1. Planting trees: spring is a favorable time to plant trees. After the soil is thawed, we should seize the opportunity to plant trees immediately. Plan and design before planting large and small trees, dig (plane) a good tree hole in advance, and do as you dig, transport, plant and water. When planting shrubs, they should also be dug, transported and planted, and fully watered to improve the survival rate of seedlings.

2. Spring irrigation: due to spring drought, windy and large evaporation, green land should be watered in time in order to prevent spring drought.

3. Fertilization: after the soil is thawed, base fertilizer is applied to plants and irrigated. {maintenance measures of southern plant sea jujube.

4. prevention and control of diseases and insect pests: this month is the critical moment for the prevention and control of diseases and insect pests. Some seedlings appeared coal fouling disease, melon seeds and yellow poplar leaf roller also appeared (using spraying fenitrothion and other pesticides for control). The method of digging pupae can continue to be used to control diamondback moth.

April: as the temperature continues to rise, trees sprout and blossom or spread their leaves and begin to enter a period of vigorous growth.

1. Continue to plant trees: in the first ten days of April, we should seize the time to plant trees that sprout late, remove and replant shrubs (rhododendron, safflower, etc.) that die in winter, and fully water newly planted trees.

2. Irrigation: continue to water the green space in a timely manner.

3. Fertilization: combined irrigation of lawns and shrubs, topdressing available nitrogen fertilizer, or foliar spraying as needed.

4. Pruning: cut off the dry branches in winter and spring to trim the evergreen hedge.

5. Prevention and control of diseases and insect pests: (1) after the second molting, scale insects gradually transferred to bark cracks, tree holes, trunk base, wall corners and other places to secrete white waxy cocoon pupation. Can be swept with a hard bamboo broom, and then concentrated deep burying or soaking. Or use the method of spraying fenitrothasone and other pesticides. (2) the longicorn beetle begins to move. You can use a grafting knife or self-made steel wire to remove the larvae, but the smaller the wound, the better. (3) Prevention and control of other diseases and insect pests.

6. green space conservation: pay attention to the picking of weeds and climbing plants in large green space. Grass picking and edge cutting should also be carried out on the lawn.

May: the temperature rises sharply and the trees grow rapidly.

1. Watering: trees need a lot of water when they are in full bloom, so they should be watered at the right time.

2. Pruning: pruning residual flowers. The street tree is pruned for the first time.

3. prevention and control of diseases and insect pests: continue to catch longicorn beetles. The first generation of diamondback moth hatched, but it has not reached the degree of harm, so the corresponding measures should be taken according to the actual situation in the conservation area. Coal fouling disease caused by scale insects and aphids has also entered a peak period (on crape myrtle, Haitong, oleander, etc.). In mid-and late May, 10-fold pine resin mixture and 50% trithiophos emulsion 1500-2000 times were sprayed to control diseases and kill pests. (other available pesticides such as insecticides, Huabao, etc.)

June: the temperature is high

1. Watering: plants need a lot of water, so they should be watered in time, not "watching the sky to eat".

2. Fertilization: combine loosening soil and weeding, fertilization and watering to achieve the best effect.

3. Pruning: continue to peel off buds and remove tillers from street trees. Pruning hedges, balls and some flowering shrubs. {maintenance measures of southern plant sea jujube.

4. Drainage work: when there is heavy rain, we should pay attention to the drainage work in low-lying areas.

5. Prevention and control of diseases and insect pests: when the diamondback moth enters the peak incubation period in mid-and late June, timely measures should be taken. Now 50% fenitrothion emulsion is basically sprayed with 500-800 times liquid. (or sprayed with compound BT emulsion) continue to capture longicorn beetles by hand.

6. Do a good job in the inspection in front of the flood prevention platform for trees, and straighten, reinforce and re-bind the trees that are loose and inclined.

July: the temperature is the highest, and there will be strong winds and heavy rain after the middle of the year.

1. Transplant evergreen trees: during the rainy season, conifers and bamboos can be transplanted with sufficient water, but pay attention to weather changes and water them in time once they encounter high temperature.

2. Drainage: drainage should be done in time after heavy rain.

3. Topdressing: dry application of quick-acting fertilizer such as nitrogen fertilizer before rain.

4. Street trees: carry out anti-Taiwan peeling and pruning, trim all branches that are in contradiction with electric wires, and check the stumps one by one, and immediately straighten and tie them up when they are found to be loose and unstable. Prepare the labor organization, materials, tools and equipment in advance, and send someone to inspect it at any time to deal with the dangerous situation in time.

5. control of diseases and insect pests: continue to control longicorn beetles and diamondback moths. To control longicorn beetles, 50% fenitrothion 1:50 liquid injection can be used to control longicorn beetles, (or Guoshubao, or Yuanke No. 3), and then seal the hole, which can also achieve good results. Cinnamomum camphor nest borer should be cut off in time and the nest should be destroyed so as to avoid further harm.

August: it is still the rainy season

1, drainage: after heavy rain, the low-lying water should be drained in time.

2. Taiwan prevention of street trees: continue to do a good job of Taiwan prevention of street trees.

4. Weeding in the middle ploughing: weeds are also growing vigorously, so weeds should be weeded in time, and can be combined with weeding for fertilization.

5. prevention and control of diseases and insect pests: mainly catch longicorn beetles, pay attention to the capture of longicorn beetles in the root. The harm of aphids and camphor nest borer should be controlled in time. Attention should be paid to powdery mildew and rot in wet weather, and timely measures should be taken. September: the temperature has dropped, welcome the National Day to do a good job of related work.

1. Pruning: greet the appearance of the city and peel the buds below the third-level bifurcation of the street tree. Hedge shape trimming. Weeding in the green space, cutting the lawn edge, cleaning up the dead trees in time, so that the trees have green branches and green leaves, and the green space is clean and tidy.

2. Fertilization: for some trees whose growth is weak and the branches are not full enough, some phosphorus and potassium fertilizer should be applied.

3. Prevention and control of diseases and insect pests: perforation disease (cherry blossom, peach, plum, etc.) was the peak, and 1000-fold solution of 500% carbendazim was used to prevent infection. Longicorn beetles began to turn to root damage, pay attention to the capture of root longicorn beetles. The wood beetle moth on poplar and willow should also be controlled in time. Do a good job in the prevention and control of other diseases and insect pests.

4. Do well the inspection of all kinds of greening facilities before the festival.

October: the temperature drops, the early winter begins in late October, and the trees begin to shed their leaves and enter the dormant period one after another.

1. Be prepared to plant trees in autumn. As soon as the leaves of a hardy tree fall, you can start planting.

2. Green space conservation: timely removal of dead trees and timely watering. The work of picking grass and cutting the edge of green land and lawn should be done well. Fertilizers should be applied if the grass flowers do not grow well.

3. Control diseases and insect pests: continue to catch root longicorn beetles. Camphor nest borer should also pay attention to observation and control. November: the soil begins to freeze at night and enters the middle of winter.

1. Tree planting: continue to plant hardy plants and complete the soil before freezing.

Part 8: cultivation and Conservation of Palm plants

Palmaceae is a very characteristic evergreen plant in Monocotyledon class, its stem is solitary or tufted, erect or climbing; leaves gather at the top of the stem, developed roots, drought tolerance, barren tolerance, strong resistance to diseases and insect pests, excellent effect in creating tropical landscape style. This edition will introduce its introduction, transplanting and disease control.

Brief introduction of introduction process

There are about 2400 species of palms belonging to 183 genera in the world, which are widely distributed in tropical and subtropical humid areas of the world. High temperature and high humidity are important conditions for the normal growth and development of most palm plants. a few palm plants have a unique ability to adapt to adverse environment, such as silver jujube (wild jujube) distributed in extremely arid areas on the edge of the desert. and many palm species that can endure flooding for a long time, such as swamp palm. Most palm plants are rich in fiber, tough stems, well-developed roots, and strong wind resistance, such as false betel nut and sunflower.

Since the 1940s, the landscape effect of palm plants has been recognized in the construction of many tropical and subtropical cities around the world, and they have been used as key varieties for urban greening and beautification, such as Miami in the United States, Jakarta in India, Bangkok in Thailand, and Cape Town and Singapore in South Africa.

Some garden companies in Guangdong began to introduce and apply palm plants since the early 1980s. Over the next two decades, southern provinces such as Guangxi, Fujian and Yunnan, as well as Jiangsu, Zhejiang, Shanghai, Chongqing and Yunnan, have successively set off an upsurge of introduction, production and application of palms.

According to the theories of plant geography and ecology, several units headed by Guangdong Palm Garden Company observed and studied the growth and mortality of introduced and domesticated palms. It is found that the plants originating from the northern hemisphere generally have the potential of cold tolerance because of the ancient glacial climate, while the species native to high latitudes and high elevations in the southern hemisphere also have strong cold tolerance. Through the study of cold tolerance and cold tolerance mechanism of palm plants, researchers found that the main factors affecting introduction and domestication are temperature, light, humidity, moisture, soil and so on. The most significant role of temperature factor is to dominate the growth and development of plants, and low temperature in winter is the dominant factor affecting the success or failure of palm introduction and domestication; through the study of salt tolerance and shade tolerance of palms, researchers have selected a number of varieties with strong salt-alkali tolerance and shade tolerance; at the same time, through the prevention and control of diseases and insect pests such as palm Phytophthora, coconut leaf beetle and red palm weevil, the incidence of palm diseases and insect pests has been greatly reduced. In addition, the researchers also studied the mechanism of palm seed germination, summarized and invented the technology of palm seed germination, and mastered the techniques of full crown transplantation and large container seedling cultivation of palm plants. and effective work has been done on soil improvement, cold protection and conservation in winter.

At present, researchers have selected and popularized about 80 species of palm plants in South China, including Dawang coconut, sunflower, palm bamboo, southern coconut, fish-tail sunflower, and so on. More than 10 species of palm plants have been successfully applied in Shanghai and its surrounding areas, such as Budi coconut, Washington palm, Canary jujube, Washington coconut, and so on.

Take Washington Brown as an example.

Discussion on the occurrence and control of Phytophthora

Harm and general symptoms of Phytophthora palmiti

The disease is often harmful to palm plants such as coconut, sunflower, Washington brown, old sunflower, Canadian jujube, etc., the heart leaves of the diseased plant can not erupt normally, the new leaves shrink and wither, and in serious cases, the whole plant wilts. The pathogen of Phytophthora is caused by Phytophthora and can be identified by incubator. The pathogen overwintered mainly in the soil or on the remains of diseased plants. Germs spread through watering, rain splash, air flow and so on.

Incidence regularity of Phytophthora in Washington

The disease occurred during the period of high temperature and humidity in summer and autumn. Poor management before drought and rain or after transplanting, such as pouring water, soil water content

Plants that are suddenly elevated, poorly ventilated, or located in the tuyere are susceptible to disease. The disease is serious in low-lying, poor drainage and continuous cropping land. In addition, the disease is often related to serious root injury caused by digging seedlings and long-distance transportation.

When it occurs, the base of the undeveloped young heart leaves rot, and the leaves are grayish green and drooping, which can be pulled out with a little effort. Dissecting the stem, it can be seen that there are paste secretions and foul smell in the growing point and even the heart of the whole plant, and white mildew can grow in the susceptible tissue. Seriously affected plants often suffer from root damage, and the main symptoms are blackening and rotting of the roots.

Taste. The disease mainly occurs in the seedling stage and nursery, and the adult trees planted on the green space rarely occur.

Symptom

In recent years, the damage in the nursery is quite serious. At the initial stage of the disease, the yellowish-brown watery spot occurred near the ground, the spot expanded rapidly, slightly sunken, the surface was dense white cavernous mold when it was wet, and the disease part rotted and smelly. When the disease occurs on the leaves, the diseased part is yellowish brown and white mildew grows under wet conditions. When the disease occurred on the stem, it was dark green at first, then expanded, moist and softened, and the upper part of the stem withered in the later stage. The disease can harm the whole palm plant. Sometimes the roots and stems are cut open with purulent fluid exudation, and in severe cases, the veins of young leaves have a large number of gray-black mycelia. Phytophthora is a vascular bundle disease. In severe cases, the whole plant wilts, droops and dries up to death, and the mortality rate is high.

According to the investigation, the peak period of the disease is the period of high temperature and humidity, that is, the optimum temperature is 27 ℃ to 35 ℃. For example, in 2006, the onset period in the coastal areas near the Pearl River Delta was from July to October, from August to November in Xiamen, from June to September in Shanghai (also in early spring), and from August to November in the mountains in the western Pearl River Delta. However, the disease can be seen in all parts of the country from January to February after typhoon and rainstorm. Sometimes sporadic, sometimes in patches.

1. Prevention of cultivation measures

1. Pay attention to the ventilation, dryness and drainage of the nursery, trim the leaves appropriately in autumn and winter every year, and dig holes and cultivate the soil to keep the nursery dry. Potassium fertilizer can be applied at ordinary times, quicklime and superphosphate can also be applied respectively to enhance plant tissue density and infection resistance and improve plant disease resistance.

two。 To select a good plot, it is necessary to choose loam or sandy loam land with high topography and good drainage for planting.

3. Rotation is implemented, requiring rotation for more than three to four years on land that has been planted with Washington brown.

4. Strengthen field management, increase the application of organic fertilizer, promote plant growth, deep roots and leaves, and improve resistance. Carry out high ridge (border) cultivation. Proper control of watering in the rainy season, timely drainage after rain, so that the rain is dry; timely watering in case of drought, flooding is strictly prohibited during watering, and carried out in sunny afternoon or evening.

5. Give priority to prevention and comprehensive prevention. Usually pay attention to observation, often prune dead branches and leaves, find diseased plants, clean them up in time, bury them deeply or burn them, and disinfect the diseased points with lime.

II. Chemical control

One or two months before and during the onset of summer, 64% alum wettable powder (1 ∶ 500 to 600), 80% aluminum ethyl phosphate (1 ∶ 400), or other dioxin, such as carbendazim, that is, Tushuxiao (common dosage is 600 to 700 times), stone sulfur mixture (1 ∶ 1 ∶ 100), dioxone (500 times), etc. Specific prevention and control methods: when transplanting Washington brown, first spray the planting site and Washington brown roots with 600 to 700 times solution of soil bacteria, or dig a pit to sterilize in the sun on a continuous sunny day, or sprinkle lime powder to disinfect, or disinfect the soil with 500 times solution of dimethazone.

After the typhoon, timely spray disinfectant alum (better) or ethyl phosphate aluminum (easy to produce drug resistance), add 0.4% washing powder to heart or spray prevention and treatment. It can also be sprayed with 80% mancozeb 700 times solution, once every 7 to 10 days, even two or three times, which can effectively prevent and control the occurrence of Phytophthora. After taking this measure, the incidence of Washington Brown and Mao Washington Brown in the Shanghai base of Guangdong Palm Garden Company has dropped from 20% in 2004 to less than 10%.

Experience of prevention and treatment

The control effect of carbendazim is not obvious. At the initial stage of the disease, if all the leaves are cut off and transplanted elsewhere, about 30% of the plants can be revived one after another after 2 to 3 years, but the growth is poor.

It is understood that the disease rarely occurs in high-temperature and dry areas such as Los Angeles, so the disease is related to high temperature and humidity, and it is infected through surface water, groundwater and Rain Water. When the roots, trunks and leaves of the plant are damaged, the bacteria invade and multiply in large quantities when the water is sufficient, which eventually leads to the blockage of vascular conducting tissue and the loss of water and wilting and death of the plant. In fact, the heart rot introduced in the literature is also Phytophthora, but it occurs in the heart lobe.

The disease is different from anthrax, which occurs in leaves, appears watery spots, and then expands into larger spots, which is easy to be found. generally, carbendazim and other agents can be used for prevention and treatment. As for leaf spot disease, it refers to the disease on leaves, the common pathogens are leaf spot mold, Alternaria, and so on, which often cause leaf blight, but anthracnose and leaf spot rarely cause plant death. Technique of transplanting large seedlings of single stem

Preparation before transplantation

l. The roots of the seedlings to be transplanted were cut in advance, the size of the soil ball was twice the diameter of the ground, and the depth of the roots was 50 cm to 60 cm. The broken root soil should be backfilled in time after removing stones and broken roots, and do a good job of moisturizing: the purpose is to calcine the adaptability of seedlings and tend to grow new roots. After cutting the root, it is best to retain it for more than 30 days, and not transplant until the new root begins to germinate. If the use of false planting seedlings, the effect is better.

two。 Dig holes and prepare for ploughing. The planting site is burrowed 20 days before transplantation, and the size of the hole is generally 1.5 times that of the earth ball. When the burrowed soil is exposed to the sun in the open air for a period of time, it is best to use pre-prepared mixed soil: pond mud + farm manure or mushroom soil + appropriate amount of mature phosphate fertilizer + appropriate amount of river sand, sand ∶ mud is 4 ∶ 6.

Planting time

The Pearl River Delta region can be transplanted throughout the year, preferably in spring and autumn, and try to avoid summer and winter, especially in January and July. Palm plants mostly like temperature and humidity, the summer air temperature is high, and the seedlings evaporate quickly, which is easy to cause too much water loss and affect survival; in winter, the temperature is low, there is even frost in some places, and the strong north wind is easy to cause frostbite or even freeze to death of seedlings.

Transplanting seedlings

The stem of some single-stem palm seedlings is thicker, the workload of transplanting is heavy, and the seedlings are easy to be injured, so it is necessary to use gunny bags or straw to cover the trunk, especially the green trunk at the boundary between the trunk and petiole. One is to protect and expand the tree trunk, and the other is to moisturize and protect against the sun. In addition, the seedlings are combined with pruning leaves to remove old leaves and retain 40% to 45% of the leaves (depending on the strength of the tree). At the same time, cut off the leaf and petiole to reduce the evaporation of water.

Planting

The seedlings had better be planted on the same day. If the time is too long, the water evaporation of the seedlings is large, and it is easy to survive due to water loss. If you can't finish planting on the same day, cover it with a shade net and spray a small amount of water on the leaves every day to shade and moisturize.

1. Return to the soil to set the position of the seedlings, that is, to return to the soil. When you return the soil to half the height of the earth ball, the loose soil will be compacted first. After returning to the soil, the mound is made into a "water storage basin" with a slightly higher surrounding and a slightly lower middle to facilitate water retention and moisturizing.

two。 Immediately after dripping water back to the soil, immediately drench the root water, before dripping water, use bamboo sticks to insert the loose soil around the soil ball, until the loose soil no longer sinks.

3. There are many kinds of fixed supports, and the triangular support made of three bamboo poles is the most economical and practical one. The height of the binding is at 2 stroke 3 of the trunk.

Post-planting management

l. Moisturizing spray leaf and trunk bandage twice a day, except in rainy days, to spray wet leaf and trunk bandage. The roots are not drenched with water, because there is excess water flowing down, and the stagnant water causes rotten roots. Cover straw around the tree head to prevent the soil from hardening caused by excessive soil temperature difference, and keep the soil around the soil ball loose, moist and aerated, which is conducive to the germination of new roots.

two。 Fangfeng is generally tall because the large seedlings of single-stem palm plants are generally high, and they are often affected by thunderstorms and strong winds after transplantation, so it is necessary to regularly check whether the support is loose after planting, especially if you find that the trunk is tilted after the gale.

3. About a month after topdressing, urea water can be used as extra-root topdressing, spray, topdressing time about half a month. After the first new leaf is grown and ripe, dig holes and fertilize with fully mature peanut bran. The hole-digging position is outside the edge of the soil ball to open a circular trench with a width and depth of 30 cm, and the fertilizer and backfill should be mixed evenly.

4. Because of the relatively weak tree potential, the newly transplanted single-stem palm seedlings are extremely vulnerable to diseases and insect pests, especially young leaves and heart leaves. Insecticidal can be killed with 5% methamidophos and 5% omethoate. At present, the invasive pest "coconut leaf beetle" is very harmful to palm plants. Adults and larvae concentrate on the foliage of heart leaves that have not yet been unfolded, resulting in the death of some or all of the newly extracted leaves and slow growth of the damaged plants. even withered. There are the following prevention and control methods: ① 81% marathon emulsion 1000 times, ② cypermethrin 500x solution, ③ use of "coconut Jiaqing", can achieve a good control effect. According to the actual operation, the author thinks that the most simple, convenient and long-term method is to combine with binding "Coconut Jia Qing" to prevent and cure it on the heart leaves.

About a month after planting, palm science university seedlings can determine whether they survive according to whether their leaves remain green or not, but in order to really determine their survival, it is generally necessary to wait for a growing season and take whether they have sent out new shoots and roots as the standard. After the author adopts the above transplanting techniques, the transplanting survival rate is increased from 75% to more than 90%, and the above techniques are highly operational, so it is necessary to popularize and apply them.

Transplanting techniques of seedlings, big trees and clump seedlings

Key techniques of seedling transplanting

Palm plants are most suitable for transplanting within a period of time after they germinate and take root. At this time, the seedlings are small and can be transplanted with seeds. in addition, there are few whisker roots, so it is not easy to damage the roots when transplanting seedlings. Using nutrition bag to raise seedlings, the size depends on the time of cultivating seedlings. Generally speaking, it is appropriate to use 16 cm × 18 cm container for 1-year-old seedlings and 19 cm × 20 cm for 2-year-old seedlings. Too small nutrition bag is not conducive to the rapid growth of seedlings. Loose topsoil, burning soil and wheat bran were mixed with a small amount of phosphate fertilizer according to the ratio of 5 ∶ 2 ∶ 1, and then bagged. First put in half a bag of mixed soil and then release the seedlings, then straighten the seedlings and compact them, so that the roots of the seedlings are close to the mixed soil and drenched through water. Palm plants should not be planted too deep, otherwise the growth of seedlings will be affected. When it is too deep, the seedlings should be lifted up to make the roots of the seedlings expand.

Key techniques for transplanting big trees

Palm plants are cultivated in the nursery for 5 to 10 years, and most of them need to be transplanted in separate beds for several times, so sparse planting and strong seedlings are selected, and the survival rate is higher.

To reduce the damage to the root group, the root tissue of palm plants is young, and there are many lateral roots and capillary roots. When digging, they should take large soil balls as much as possible and prevent them from loosening and cracking. The course of root injury should be reduced to a minimum in order to maintain normal respiration and water absorption and improve the survival rate of transplantation. During the construction, the line should be accurately laid out and the hole should be determined to avoid overwork and prevent the soil ball from being loose.

The amount of leaves retained in leaf pruning and transplanting should be comprehensively determined according to different species, climate at the time of transplantation, transplantation and maintenance conditions.

Generally, about 40% of the original number of leaves should be retained. Too many leaves will lead to withered and yellow leaves due to large water evaporation; if there are too few leaves, the plant recovery is difficult and the cycle is long, and the initial landscape effect is not good.

In the process of digging, transporting, loading and unloading the stem and its pseudostem, the stem should be protected from damage, and the part of the pseudostem should not be squeezed and bent, which is the guarantee of plant health and rejuvenation as soon as possible.

Palm plants in the newly planted soil will damage the root tip during transplantation, and it is difficult to germinate new root tip within one month after transplantation, so the water absorption capacity is weak. At this time, good water permeability and air permeability of the soil is conducive to the survival of seedlings, so large holes should be dug and attention should be paid to the quality of guest soil, and peat soil and compound fertilizer should be added to facilitate recovery after palm planting.

Maintenance within one month after planting, the adaptability of the plant is poor, to deal with the careful maintenance of seedlings, must be timely replenishment of water, proper shade, and strive to make it have new leaves to sprout within three months. If there is a rainy climate for several consecutive days after transplanting, palm seedlings will recover better because they can avoid the influence of adverse factors such as hot sun on rainy days.

Key techniques for transplanting large-scale clustered seedlings

The tufted species of Palmaceae have multiple growing points and can grow new roots more quickly after transplanting. However, tufted palms also have some disadvantages, such as large water evaporation due to trunk weight and large leaf area, and being vulnerable to strong winds because of poor air permeability. Therefore, in addition to the disposal according to the transplantation of dry palms, the following technical measures should be added:

1. After the implementation of the "hairy root method" transplantation, after digging up the larger soil balls, use a small shovel to remove part of the soil along the outer edge of the soil balls, retain more fibrous roots and moderate soil balls, and immediately outsource moisturizing lightweight materials to reduce the weight of the soil balls and ensure survival. For example, this method can be used for the transplantation of clump palms with slow recovery, such as fishbone sunflower and betel nut.

two。 The implementation of bare root pseudo-planting or pot planting concentrated maintenance until the new root germination, plant stability before formal planting. This method is suitable for rough tufted palms such as loose-tailed sunflower, strange wrinkle palm and Hawaiian coconut, which can reduce freight and facilitate construction.

In short, the transplantation of large seedlings and big trees of palm plants is to grasp five aspects, namely: selecting strong seedlings; digging soil balls and carefully transplanting seeds; moderately pruning leaves; doing a good job of ventilation and drainage of planting land; and sun protection and moisturizing after planting. The sign of the success of transplanting big seedlings and trees is that most of the leaves can be preserved and new leaves can be sprouted within half a year after planting, among which three healthy new leaves can be used as the complete success of the transplant.

Drainage: the hydrological condition of the planting land should be understood first, and the bottom of the soil ball should be placed at the position where the soil ball is 100-150CM above the perennial underground water level line and the soil layer is thick. at the same time, the underground soil ball root hydrophobic layer and the surface runoff drainage network should be done well to prevent the soil ball from accumulating water after planting. If the hydrological conditions can not meet the requirements, the method of throwing high soil balls can be adopted, that is, mixing fertile soil with loose medium or heaping high planting land with coarse sand to meet the above requirements as far as possible, and then placing the plant on the soil mound, and filling the soil ball with mixed loose soil or planting soil mixed with rot soil; remove debris from the soil around the planting site, or properly use loose medium to improve the soil, so as to achieve the condition of loosening and ventilating the root of the plant. Strengthen the inspection in the rainy season, dredge the drainage facilities and loosen the soil at the roots in time, so as to prevent waterlogging and drainage. Moisturizing: immediately after planting, the fixed root water should be irrigated to ensure that the root of the soil ball is moist and closely combined with the surrounding soil to promote the development of the root system, and then irrigate the soil ball three times in time to prevent the topsoil from cracking. In the hot summer, more water should be sprayed on the ground and canopy to increase the ambient temperature and reduce transpiration; the moisturizing treatment of the leaf surface includes: a, the newly planted seedlings should be properly built to reduce the transpiration area of the leaves; b, anti-transpiration agents should be properly sprayed on the leaves to inhibit the physiological metabolism of plants and reduce the physiological dehydration of plants. C. Under fine weather conditions, we should spray water to the leaves as much as possible, strengthen the water absorption of leaves and weaken transpiration; check the water status of soil balls and roots at any time and replenish water in time to ensure the moisture of soil balls and the permeability of root respiration. Fertilization: after planting, in addition to moisturizing the plant, foliar fertilizer with appropriate low concentration can be sprayed to strengthen the nutritional supplement after planting. Check the root germination status of the plant frequently, if it is found that the plant grows new roots, you can consider increasing root fertilization, generally choose the season when the monthly average temperature is higher than 20 ℃, apply organic fertilizer as much as possible, and properly apply compound fertilizer with high P and K content, so as to promote the nutritional balance of the plant and ensure its Shaanxi to restore healthy growth. Pest control: spraying medicine before the nursery comes out of the nursery, and after arriving at the construction site, it is also necessary to spray the plant before unloading, and to ensure that the plant is sprayed three times at intervals of one week to ten days after planting, and then it is necessary to formulate a reasonable pest control plan.

General situation of project

Shilien (Nanjing) Optoelectronics Co., Ltd. is located at No. 31 Hengfei Road, Nanjing Economic and technological Development Zone, with a green area of 28186 square meters. The greening plant configuration in the factory area is relatively reasonable, the color is rich, and the seasonal change is obvious, forming a hierarchical and natural ecological plant community, which basically shows the natural landscape of plants. The configuration of plant flowers, shrubs and hedges among factories makes each plant form different landscape styles. The factory has planted dozens of plant varieties, such as camphor, magnolia, beech, sweet-scented osmanthus, crape myrtle and so on, among which there are boulevards composed of camphor, ancient red maple, fruit pomegranate, Xifu begonia, ginkgo, Canadian jujube and other varieties.

In view of the existing situation of the greening landscape in the factory area, we think that the initial construction of greening is relatively extensive, and the understanding of plant habits is not enough, especially the replacement of planting soil in the greening land is not in place, and the garbage soil in some areas has not been replaced, resulting in poor plant growth.
