What about the withered Australian fir leaves, replenishing light / reasonable fertilization / replacing alkaline soil

As one of the three largest ornamental trees in the world, Australian fir is very effective. It not only looks good, can relieve eye fatigue, but also has a powerful function of purifying air. But when the Australian fir leaves wither, all this good will leave us, at this time flower friends must be very urgent! So, what if the Australian fir leaves wither? Today, the editor is here to solve this problem for everyone.

1. What if the Australian fir leaves wither

What should we do if the Australian fir leaves wither? if the light is insufficient, add light; water too much, loosen the soil and dry the soil, or cut off the roots to change the basin soil; when the nutrients are insufficient, apply the right amount of fertilizer; when you fertilize too much, dilute the irrigation, or cut off the roots to change the basin soil; when the soil is too alkaline, change the slightly acidic soil; when you encounter bugs, spray with medicine. Specifically, let's move on.

2. the causes and solutions of the withering of Australian fir leaves.

1. Lack of light

Australian fir bogey strong light, more resistant to shade. In indoor farming, many flower lovers often focus only on shading the bright light, neglecting that it also needs sufficient light. As a result, the leaves of Australian fir will slowly wither in a long-term shady environment.

Solution: Australian cedar Xi astigmatism, we should put the Australian fir in the indoor semi-shade, let it receive enough light, it will slowly get better in a few days.

2. Overwatering

Australian cedar avoid stagnant water, we can not water too much. But in indoor farming, many flower friends like watering, regardless of the lack of Australian fir, as a result, watering too frequently, resulting in stagnant water in the basin. Australian fir roots soak in the water, breathing will not be smooth, the leaves will naturally wither. Over time, the roots will rot, and in severe cases, the plants will die.

The solution: first loosen the soil for the Australian fir with tools, and then put it outside in the sun to allow the water to evaporate quickly; if the roots are rotten, we need to take off the basin, cut off the rotten roots, and then replace the pot soil and replant it.

3. Improper fertilization

Insufficient fertilization: adequate nutrients will make Australian fir grow luxuriantly, correspondingly, if insufficient fertilization, resulting in lack of plant support, its leaves will slowly wither. Solution: appropriate amount of fertilizer, fertilizer to the florist to buy, remember not to apply too much at a time.

Excessive fertilization: although Australian fir likes to be fertilized, once it is fertilized too much, or too thick, it will cause root burning. The roots are burnt, naturally can not absorb nutrients, although the leaves will grow, but will slowly wither. Solution: irrigate and dilute the fertilizer to let it flow out from the bottom of the pot, and if the root is burned, you need to cut the root to change the soil, and then replant it.

4. Soil alkali.

Australian cedar prefers slightly acidic soil, which is not suitable for growing in soil with too high alkali content. Once the soil is alkaline, there will be symptoms of Australian fir leaves withering.

Solution: it's simple to change the basin soil, replace it with fertile, slightly acidic soil with good drainage, and then replant it.

5. Insect damage

In addition to the above points, the withered Australian fir leaves may also be attacked by insects. Usually this pest is a scale insect, which eats the roots of Australian fir in the soil.

Solution: we should put some medicine in the soil to kill shell insects. If the bite is not serious, it will recover soon.

Generally speaking, as a common potted plant, the culture method of Australian fir is not difficult, even if the novice, according to the requirements to maintain, can also raise it well. Of course, there is no need to worry about the phenomenon of wilt, just solve it according to the above method. With regard to the withering of Australian fir leaves, the editor has introduced this, hoping to give you some help.

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 2cm, and the row spacing is 2cm × 8cm. After pouring water, set up a bamboo bow on the seedbed, then cover it with plastic film, press it tightly with mud around, shade the light in a double-layer shade, keep the bed moist, control the temperature in the film at about 30 ℃, and keep the humidity above 90%. Generally, a large number of cuttings can take root after one month.

3. Grafting

Grafted, potted seedlings of Chimonanthus praecox were used as rootstocks, excellent varieties of Chimonanthus were grafted, and potted Magnolia and Magnolia seedlings were used as rootstocks to graft Magnolia and Michelia. Budding, using wild rose seedlings as rootstocks, grafting to breed excellent rose varieties; using apricot, peach, plum and other annual seedlings as rootstocks, budding breeding Birthday Bun with Bean Paste Filling, green peach, purple leaf plum, red leaf peach, Yu plum, plum blossom, etc.; using 1-2-year-old maple seedlings as rootstocks, grafting breeding red maple, feather maple, red maple and so on. Branch grafting, Camellia oleifera, Camellia oleifera or Camellia oleifera seedlings as rootstocks, Camellia oleifera and Camellia oleifera as rootstocks, "Purple Butterfly" and "Jade Butterfly" in rhododendron as rootstock, split or abdominal grafting of Belgian rhododendron or western rhododendron.

4. Pressing strip

The flowers and trees that can be propagated by pressing in June are: rhododendron, honeysuckle, eight immortals, snowball, Qionghua, brocade, oleander, sweet-scented osmanthus, camellia, plum, wax plum, clove, gardenia, red maple, Milan, pearl orchid, jasmine, magnolia and so on.

5. Ramet

The flower species that can be propagated in June are: kidney fern, calla lily (after anthesis), Phyllostachys pubescens, dry umbrella grass, purple evergreen, pineapple, twelve volumes, one-leaf orchid, calamus, Ophiopogon, and so on.

II. Seed harvesting and transplanting

1. Harvest seeds

The grass flower seeds that can be harvested in June are: carnation, cornflower, goldfish grass, dwarf snow wheel, high snow wheel, hollyhock, mallow, primrose, bungee, Zhu Dinghong (sown with picking) and so on.

Flower and tree seeds that can be harvested in June: after harvest, if the nursery conditions are not allowed, the detached seeds can also be dried and sown until next spring, which will not affect their germination rate; peaches and apricots should be sowed as they are picked, or the seeds should be stored in the crack to germinate and then sow. The sweet-scented osmanthus seeds harvested in June were removed from the fleshy pericarp and washed, stored in wet sand to promote the post-ripening of the embryo, and then sowed in the nursery when they germinated.

two。 Transplanting, planting and potting

In June, a considerable number of grass flowers need to be transplanted and planted or put on the pot. they are: evening primrose, drunken butterfly, impatiens, guinea impatiens, primroses, ornamental peppers, winter corals, red tobacco, petunia, marigold, peacock grass, hundred-day grass, thousand-day red, a string of red, dragon mouth flower, ground skin, sulfur chrysanthemum, cockscomb, red-green grass and so on.

In summer, some large flowers and trees are no longer transplanted, so as not to affect their survival rate and growth after transplanting. However, for some small flowering shrubs, such as star anise gold plate, broad leaf ten meritorious service, ten meritorious service, hypericum, gardenia, Phnom Penh privet, red leaf Berberis, boxwood, under special circumstances, transplanting with the ball is fine, just as the old saying goes: "never move, do not call tree knowledge", but it is necessary to strengthen the management of water spraying and shading after transplanting.

III. Flower management

1. Watering

Watering potted flowers in June should pay attention to the following aspects: first, watering time, 10:00 or 5pm is better, usually watering once a day; second, watering temperature, watering water should be kept basically consistent with basin soil temperature, if the difference between water temperature and soil temperature is too large, it will cause potted flower roots and leaves to be stimulated and then affect their growth. Third, the combination of watering and spraying, when it has not rained for several days, in addition to watering the basin, it is also necessary to spray water around the leaves and potted flowers in order to improve the humidity of the local space. If there is a continuous cloudy day, it depends on the dry and wet condition of the basin soil to decide whether to give watering and spraying.

A species of flower that enters semi-dormancy or dormancy in summer. Semi-dormant people such as safflower sorrel, geranium, golden bell, orchid, calla, begonia, etc., when the temperature is more than 30 ℃, because their growth activity is very weak and metabolic level is low, it is necessary to reduce watering and keep the basin soil moist. The types of deep dormancy, such as cyclamen, Lycoris (class), buttercup, Dutch peony, etc., show that the aboveground stems and leaves wither, the underground nutrient fibrous roots wither, and the underground stems or tubers dormant in the soil for the summer, which must be stopped watering and moved to a cool place to keep the basin soil from being too dry.

[page] if there is continuous rain, check the potted flowers thoroughly after the rain stops and find that there is stagnant water in the pot. pour them away as soon as possible, loosen the soil after the pots are dry, so as not to cause rotten roots, or knock down the potted flowers before the heavy rain, and then straighten the potted flowers after the rain stops.

two。 Fertilizer application

For exuberant species Such as tortoise back bamboo, hanging orchid, synthetic taro, bamboo, kidney fern, spring feather, iron tree, one-leaf orchid, green giant, red (green) gemstone, green emperor, green queen, rubber tree, Anthurium, red back cinnamon, palm bamboo, southern sequoia, Brazilian iron, Luohan pine, wealth tree, wax plum, rose, Magnolia, Milan, jasmine, pearl orchid, plum, camellia, tea plum, Ruixiang, rhododendron, cinnamon, five-colored plum, Longtuzhu, shrimp, dai, dai Lemon, kumquat, pomegranate, crape myrtle, pyracantha, etc. The thin cake fertilizer and water that can be retted thoroughly every half a month, and the species that are blooming, but also apply an appropriate amount of phosphorus and potassium fertilizer to meet the needs of its growth, flowering and fruit hanging.

For those flower species that are dormant or semi-dormant, fertilization must be stopped; especially for those succulent flower species, such as jade leaves, crab claw orchid, crystal cactus, cactus pen, squirrel tail, pine chrysanthemum, leopard skin flower, sedum, when the temperature reaches above 35 ℃, stop fertilization to avoid decay.

3. Pruning, picking buds

⑴ pruning Lang elm, Finch plum, Luo Hansong, Fujian tea, real cypress, juniper, bayberry, round cypress, wolfberry, holly, triangular maple snow willow, Tamarix, firethorn and other kinds of vigorous growth, the branches that affect the shape should be pruned or shrunk as soon as possible, so that the plant can maintain a hierarchical and good appearance, and can promote it to draw more short branches, send more new buds, and form a perfect shape as soon as possible.

When ⑵ picks buds from Milan, jasmine, magnolia, rose and other flowers, the abortive stems of the remnants should be removed in time, and the branches that have flowered should be properly shrunk so as to promote the lower side branches or flower buds to bloom again. In order to promote the flowers and trees such as Magnolia, daidai, rhododendron, camellia, wax plum, plum blossom and begonia to form a good plant shape, in the same year or in the coming year, more pregnant flowers, more blossoms and good flowers, those branches that are too prosperous should be topped and budded to inhibit the growth of the main and lateral shoots and promote the germination of lateral buds.

4. Shade

In June, those flowers and trees that like shade or semi-shade must be moved to the shade to prevent the sun from causing damage to the plants. Such as Hosta, purple calyx, asparagus, camellia, tea plum, rhododendron, orchid, orchid, palm bamboo, rubber tree, fern, forest taro, fruit taro, pink daiye, spring feather, green apple, bean green, green giant, red (green) gem, green emperor, red queen, sunflower, Ruixiang, one-leaf orchid, hanging orchid and so on. Flower species that like light must be given sufficient light, such as pomegranate, wisteria, Firethorn, crape myrtle, jasmine, June snow, cycad, cypress, peach blossom, plum blossom, wax plum, elm, Fujian tea, triangular maple, sparrow plum, wolfberry bone, holly, water bayberry, oak, black pine, brocade pine, Bailan, Milan, rose, ten meritorious works, grapes and so on. Luohansong, tiger thorn, bamboo, Buddha belly bamboo, Guanyin bamboo, five-needle pine, bamboo and cypress, etc., can be given appropriate shade.

5. Prevention and control of diseases and pests

⑴ cypress, cypress, elm, papaya, pyracantha, Luohansong and begonia are easy to be harmed by longicorn beetles, so poison label should be used in time to prevent and cure them.

⑵ rose, etc., are prone to powdery mildew and brown spot in the rainy season, so it is necessary to spray Bordeaux solution as soon as possible.

⑶ Magnolia, plum blossom and wax plum are easy to be harmed by aphids, so it is necessary to choose appropriate pesticides as soon as possible.

The leaves of ⑷ orchids are easy to be infected with anthracnose, so carbendazim and other fungicides should be sprayed as soon as possible.

⑸ daidai, lemon, kumquat, bergamot, etc., tender leaves are easy to be eaten by citrus butterfly larvae, can be sprayed with contact agents, stomach poisons and other pesticides to kill.

Fourth, bonsai modeling

Solar terms in mid-June: Grain in Beard on June 5; the Summer Solstice on June 21.

Flower planting Handbook (July)

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

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

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.

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.

For continuously flowering flowers and trees in the courtyard, such as rose, crape myrtle, five-colored plum, triangulated plum, etc., we should continue to cut off the stump and stem, and cut the branches that have flowered moderately. For the grass flowers planted in the courtyard, such as red, marigold, thousand-day red, etc., it is necessary to cut off the open inflorescences in time to promote their lateral shoots to continue to blossom and blossom, so as to prolong the ornamental period.

3. Watering. For the newly planted courtyard flowers and trees in that year, we should continue to do a good job in watering and spraying: first, we should keep the soil at the roots moist, but there should be no stagnant water; second, we should continue to spray water on the leaves. In addition, we should also do a good job of spraying water and moisturizing the newly planted grass flowers.

4. Fertilizing. For autumn grass flowers planted in the courtyard, it is appropriate to apply balanced quick-acting fertilizer of nitrogen, phosphorus and potassium; for sweet-scented osmanthus flowers that have already bloomed, base fertilizer can be opened in annular trenches; for pruned rose, begonia, crape myrtle, hibiscus, camellia, Michelia, plum blossom, wax plum, etc., appropriate amount of compound fertilizer can be applied. For Phyllostachys pubescens and Firethorn, as well as bergamot, kumquat, daidai and golden marbles in the south, a small amount of available phosphorus and potassium fertilizer can be properly applied to prolong the fruit appreciation period.

5. Pest control. Stem borer pests such as plum blossom, red leaf plum, cherry blossom and begonia planted in the ground will continue to be controlled with poison swabs. The withered branches and leaves falling in the courtyard should be cleaned and burned in time.

In addition, at the end of October, the underground roots of canna and dahlia were dug up when the aboveground part was close to withering, and the sand was stored indoors, keeping the room temperature not less than 5 ℃, and then cut and planted again in the spring of next year.

Management of potted flowers in courtyard

1. Watering. Although the weather has turned cool, in most areas south of the Huaihe River, the temperature is still above 17 ℃, and the air is quite dry, so watering of potted flowers must be managed carefully. For some foliage plants that like to be moist, such as rubber tree, orchid orchid, tortoise back bamboo, green apple, synthetic taro, ash ash wood, orchid cinnamon, hulk, ruby, etc., it is appropriate to water once a day in sunny days, supplemented by foliar spray; for summer dormant flowers that resume growth after entering autumn, including semi-dormant species, such as calla lily, cyclamen, gentleman orchid, purslane, incense, geranium, hanging bell crabapple, etc., need to increase the amount of water. For wax plum, plum blossom and camellia that blossom in winter and early spring, watering should be controlled and more water should be sprayed to facilitate the expansion of the bud. For the cold-afraid flower species in the northern region, it is necessary to reduce watering, which can accelerate the Lignification of their new shoots, so as to facilitate their safe passage through the winter. The best watering time is 10:00 or 3pm.

2. Fertilizing. For summer dormant flowers that resume growth after cool autumn, it is necessary to apply low concentration quick-acting liquid fertilizer in time; for camellia, plum blossom, wax plum, melon and leaf chrysanthemum, primrose, gentleman orchid, cyclamen, cyclamen, Belgian rhododendron, red daffodil, etc., the mixture of 0.2% potassium dihydrogen phosphate and 0.1% urea should continue to be applied. For most foliage plants, the application of nitrogen fertilizer should be stopped after the middle of October, and some low concentration potassium fertilizer should be applied properly in order to increase the cold resistance of plants; for ornamental fruit potted plants, such as daidai, lemon, kumquat, Tianzhu, winter coral, rich seeds, golden marbles and so on, a small amount of phosphorus and potassium fertilizer can be applied in the first and middle of October.

3. Shade. For some very shady foliage plant species, such as Daifen leaf, tortoise back bamboo, bamboo taro, synthetic taro, emerald, Boston fern, pepper grass, etc., they still need to be shaded 2 to 3 hours before and after noon.

4. Trim. For most of the bonsai and potted flowers that must be moved indoors in the middle and late October, the withered branches, disease and insect branches, and thin branches should be cut off first; for the long branches, they should be shrunk in strength; the binding objects that have been modeled for 1 to 2 years can be removed, or they can be re-tied after they are untied, so that they will not be strangled and bound in a fixed position for a long time, injuring the cambium of the branches, causing the branches and leaves to die.

5. Keep out the cold. In the middle and last ten days of October in the northern region, some ornamental plant species that cannot tolerate the low temperature below 10 ℃ can be moved into the greenhouse in time; for some more hardy woody potted flowers or tree stump bonsai, they can be buried in the leeward and sunny soil at the end of the month to prevent the basin soil from freezing. The Yangtze River basin should accurately grasp the information of weather changes and avoid the threat of cold wave going south.

6. Pest control. Cut off the dead branches and leaves from potted flowers and trees, collect them uniformly and burn them. For potted chrysanthemums, aphids, chrysanthemum tigers, leaf miner larvae, inchworm and other pests should be controlled.

Potted plants suitable for balcony display

On the balcony in the first and middle of October, the light is strong and the air is dry. Only those potted flowers and trees that have been left on the balcony for a long time and have strong resistance can adapt to the open-air environment of the balcony. They are: black pine, golden pine, hammer elm, sparrow plum, triangular maple, water bayberry, white wax, Fujian tea, Luohan pine, Platycladus orientalis, round cypress, dragon cypress, melon seed yellow poplar, pomegranate, leaf flower, thick-leaf banyan, ginkgo, rose, jasmine, Milan, iron tree, firethorn, five-colored plum, Tamarix, red maple and so on. Some cold-resistant southern flowers and trees can no longer be placed on the balcony when the temperature drops to 10 ℃. For some flower species that like a cooler environment, they can be placed indoors at the beginning of the month. Such as Cymbidium, crystal candle, netted grass, Cartland, Phalaenopsis, Oncidium and so on. For some common foliage plants, they can be moved indoors in 3 to 4 hours before and after noon, and can be placed on the balcony at other times, such as palm bamboo, Brazilian wood, wealth tree, green apple, one-leaf orchid, loose-tailed sunflower, fishtail sunflower, king coconut, spotted cymbidium, goose palm wood and so on. In the north, when the temperature drops to 10 ℃, most flowers and trees can no longer be placed on the balcony. The propagation of flowers on the balcony in the first ten days of October, we can continue to use the wide-mouth flowerpot as the cutting container on the balcony, containing the mixed cutting substrate of 1% of bran ash and 1% of wet sand, or vermiculite can be used alone as cutting substrate, covered with plastic film to moisturize, and cuttings propagate a small amount of ornamental plants. Such as gardenia, goose palm wood, rubber tree, peach leaf coral, Michelia, jasmine, pearl orchid, Guangdong evergreen, coral flower, golden bract, shrimp flower, mulberry, bergamot, silver queen silk grass, golden kudzu, geranium and so on.

Management of balcony flowers

1. Watering. For woody ornamental plants placed on the balcony, such as cycads, banyan trees, rubber trees, goose palm wood, Brazilian wood, rich trees, Milan, Prynne, jasmine, etc., can be watered once a day, supplemented by foliar spray; for the already pregnant bud, the species that will blossom in winter and early spring, such as wax plum, plum blossom, camellia, tea, Belgian rhododendron, etc., should not be watered too much, and spraying the branches and leaves at the same time can effectively promote the expansion of the bud. For potted foliage plants shelved indoors, such as tortoise back bamboo, spring feather, cherry angel, one-leaf orchid, plantain, bird's nest fern, Anthurium andraeanum, taro, green apple, etc., should be watered mainly and watered as a supplement, in order to keep the basin soil dry.

2. Fertilizing. Potted flower species that resume growth from dormancy or semi-dormancy, such as Cymbidium, cyclamen, calla, and Cymbidium, pineapple, orchid, etc., can be poured with a mixture of 0.2% potassium dihydrogen phosphate and 0.1% urea; for fruit-viewing daidai, kumquat, kumquat, lemon, bamboo, golden marbles, rich seeds, hot thorns, winter corals, etc., can continue to apply a small amount of low concentration available phosphate and potassium fertilizer. For Milan, Magnolia, Pearl Orchid, Jasmine and so on, thin phosphorus and potassium fertilizer can be applied 1 or 2 times in early October to facilitate its smooth winter.

3. Shading. In the first and middle of October, in order to reduce the amount of water, protect the nutritious fibrous roots distributed on the surface of the potted soil, and prevent the consolidation of the potted soil, we can continue to cover the surface of the potted soil with wet grass, moss, wet cloth and so on, especially the shallow potted tree stump bonsai, in order to reduce the amount of water, protect the nutritious fibrous roots distributed on the surface of the potted soil and prevent the consolidation of the potted soil. For some shade-loving foliage plants, they can be moved indoors for 3 to 4 hours before and after noon in sunny weather. The sunshade net built in summer can be removed after mid-October.

4. Trim. The stump bonsai shelved on the balcony in mid-late October, such as hammer elm, sparrow plum, triangular maple, banyan tree, Fujian tea, Platycladus orientalis (pile), Luohan pine, round cypress, dragon cypress, privet, etc., must be pruned and reshaped as necessary. The wire or non-metal wire which has been bound for more than a year can be solved first. if the modeling requirement is not met, a new binding position can be changed and then fixed, so as to avoid serious damage to the plant caused by deep constriction. For general potted flowers and trees, such as rose, wax plum, plum blossom, pedicel begonia, vertical silk begonia, etc., can also be pruned appropriately.

5. Pest control. In late October, the dead branches and leaves of all potted flowers on the balcony can be collected and burned together. The stump bonsai with partially exposed xylem of the trunk can be smeared with stone-sulfur mixture, which can not only protect the xylem of the trunk, but also reduce the occurrence of diseases and insect pests in the coming year. Flower planting Handbook (November)

In winter, bamboo crabapple, borer leaf begonia, lotus leaf begonia, geranium, Fusang, hanging bell begonia, Yushu, purslane, red back cinnamon, golden bract, shrimp flower and so on can be cut and propagated in the greenhouse.

In November, ear cuttings such as hibiscus, Lingxiao and grape can be cut and stored in the Yangtze River valley, and cutting in the next spring can obviously accelerate the rooting speed and improve the survival rate of cuttings.

3. Grafting. Red maple and feather maple were grafted with green maple seedling as rootstock, red maple and feather maple were grafted with apricot seedling and peach seedling as rootstock, plum blossom was cut (grafting interface was buried in soil for overwintering), sturdy branches of rose (Elizabeth variety) were used as rootstock, branches of excellent rose were used as scion, split grafting or cutting were carried out after cuttage, interface healing and lower incision rooting were synchronized, which could speed up the process of cultivating grafted seedlings of rose.

4. Press the strip.

Among them, when transplanting evergreen trees, the branches and trunk must be properly cut or truncated, and most of the leaves must be deleted, and the trunk should be tied up with grass rope, and at the same time, a large soil ball (generally the diameter of the soil ball is about 6 to 7 times the diameter of the trunk). To ensure its survival; transplanting deciduous trees, you can cut the trunk short, cut the big branches, bring the soil balls and tie up the trunk. After transplanting, the management of watering and trunk spraying must be strengthened in order to survive. In addition, the incisions of the trunk and big branches should be sealed with wax or bound with plastic film to prevent a large amount of water evaporation in the tree.

In November, plum piles, wax plums, camellias, camellias, camellias

In November, potted hyacinths, tulips and daffodils should be transferred to the greenhouse to promote them to blossom around the Spring Festival.

1. Water it. For most of the ornamental flowers (including bonsai) placed in the greenhouse, greenhouse or room, the amount of watering in November should be based on keeping the basin soil moist and should not be too wet. if the temperature is too low and the plants are watered too much, the roots are easy to die. If the indoor temperature is high, the amount of water should be increased appropriately, and the necessary foliar spray should be given.

For those species of potted flowers that bloom before and after the Spring Festival, such as camellia, tea plum, rhododendron, plum blossom, wax plum, melon and leaf chrysanthemum, as well as fruit ornamental plants such as dai dai, bergamot, lemon, firethorn, bamboo, winter coral, rich seeds, etc., not only to keep the potted soil moist, but also to spray water frequently to the plant, so as to facilitate the expansion and growth of the plant flower buds, and also make the fruit appear more colorful.

For foliage plants shelved in greenhouses, greenhouses and rooms, we should not only keep the basin soil moist, but also spray water on the leaves regularly to keep them green and clean all the time. In the greenhouse and living room with higher temperature, the amount of water can be increased. For less hardy foliage plants, such as taro, bamboo taro, pink daiye, green emperor, variable leaf wood, silver queen, etc., the amount of water should be controlled to help them survive the winter safely.

[page] the suitable watering time for potted flowers in November is from 10 am to 11:00, and the water temperature should be basically consistent with the soil temperature, so as to avoid adverse reactions caused by low water temperature, which will affect their safety in overwintering.

two。 Fertilize. For potted flowers shelved in the room above 15 ℃, such as rhododendron, camellia, camellia, plum blossom, wax plum, golden bract, shrimp flower, Rui Xiang, melon and leaf chrysanthemum, cyclamen, tapestry begonia, hyacinth, gentleman orchid, tulip, ornamental pineapple, crab claw orchid, colorful pineapple, etc., they can continue to apply low concentrations of phosphorus and potassium fertilizer, and 0.2% potassium dihydrogen phosphate fertilizer solution can promote their growth and flowering.

For most of the potted plants, foliage plants and bonsai placed in the general greenhouse, topdressing should be stopped to facilitate its normal dormancy and overwintering. Most of the flowers and trees planted on the ground, such as begonia, Magnolia, Michelia, Gardenia, seven-leaf tree, camphor, Spiraea, sweet-scented osmanthus, grape, rose, wax plum, plum blossom, cherry blossom, trouble-free, acacia, palm, red maple, peony, golden bell, peony, hypericum, etc., can be buried with biscuit fertilizer The dosage of each plant is 0.5 kg to 1.5 kg, and the smaller plants can be less, laying a good material foundation for the growth and flowering of next year.

3. Trim. Continue to trim hedges, green walls and ball shapes that have not been trimmed, and base fertilizer can be applied after pruning.

Carry out omni-directional shaping and pruning of bonsai plant species dominated by scissors, such as hammer elm, Fujian tea, Finch, maple, oak, white wax, fire thorn, June snow, cypress, Luohan pine, wintersweet, begonia, etc., to lay a good skeleton for next year's growth.

Pruning the ground or potted rose that has not yet been pruned, except for retaining 3 to 5 1-to 2-year-old sturdy stems with a base of 30 cm to 50 cm, the rest of the old stem is amputated from its base, and all the thin branches are cut off. The current year's branches on the untrimmed crape myrtle were shrunk intensively, except for retaining 20 cm to 30 cm at the base of several thick branches, and all the other branches were cut off, so as to draw more sturdy shoots in the coming year and lay a good foundation for its more flowering.

Common flowers and trees on the flower bed, along the street, and in the courtyard, such as crape myrtle, hibiscus, sweet-scented osmanthus, camphor, Fatong, purple magnolia, Admiralty, plum blossom, wax plum, cherry blossom, camellia, acacia, firethorn, Haitong, begonia, etc., cut off all the irregular branches, thin branches, bore branches, disease and insect branches, and cut the long branches protruding the crown properly. In addition, the thick palm trees can be peeled off in November to do a good job in trunk cleaning, so that it shows its due ornamental effect.

4. Keep out the cold. Potted flowers and trees that are not too afraid of cold, such as Camellia, Camellia, rhododendron, Cymbidium, Cymbidium, Phyllostachys pubescens, Sequoia, Jasmine, Magnolia, Magnolia, Dai Dai, bergamot, lemon, kumquat, cinnabar root, goose palm wood, tortoise back bamboo, spring feather, fish tail sunflower, rubber tree, wealth tree, Canadian jujube, palm bamboo, etc., can be put in a plastic greenhouse, as long as the room temperature is not less than 5 ℃.

For non-cold-resistant potted flower species, such as bamboo taro, pink daiye, synthetic taro, deep feather split vine green velvet, Milan, variable leaf wood, golden vein jade bed, golden bract, Brazilian iron, red (green) gemstone, hulk, green emperor, silver queen, egg flower, rich bamboo, Phalaenopsis orchid, Cartland, magnolia, etc., should be kept indoors at room temperature not less than 10 ℃, or you can use a double-layer plastic greenhouse to protect the winter.

For those more hardy bonsai or potted plants, such as wax plum, plum blossom, begonia, Yingshanhong, pomegranate, hammer elm, crape myrtle, melon seed yellow poplar, Finch, Luo Hansong, five-needle pine, green cypress, round cypress, triangular maple, red maple, etc., can be directly buried in the leeward and sunny soil together with the flowerpot, under the condition of not less than-10 ℃, generally will not occur frost injury. In case of particularly cold weather, it can be covered with film soft grass to prevent cold.

For potted flowers or bonsai placed in greenhouses, greenhouses or bedrooms in November, in addition to ensuring certain temperature conditions, we should also do a good job of ventilation, which can be ventilated around noon to prevent plants from falling flowers, fruits and leaves due to being stuffed indoors for a long time; in addition, there should be no gas and other toxic gases indoors, otherwise it is also easy to cause fallen leaves and fruits. When ventilating, you should also be careful not to let the plant be directly attacked by the cold wind.

5. Pest control. For the flowers and trees which are prone to leaf diseases, such as grape, begonia, rose, rose, camellia, chrysanthemum and so on, collecting and burning the fallen leaves under their plants can significantly reduce the occurrence of diseases in the coming year.

Continue to whiten the trunk of the street; dry and split-dry stump bonsai can be coated with stone-sulfur mixture to prevent the deep decay of the stump xylem.

Whitefly and scale insects on potted flowers and trees placed in greenhouses or greenhouses (dai dai, bergamot, cycad, orchid, camellia, gentleman orchid, orchid) are all likely to be wiped off with a wet cloth and sprayed with pesticides such as quick culling.

For aphids on potted plants put indoors (which may occur in Magnolia, Milan, daidai and rose), tobacco water can be sprayed to control them.

For the rhododendron placed in the greenhouse, it is necessary to stop spraying Yemianbao fertilizer, otherwise coal pollution will occur easily due to poor indoor ventilation and high air humidity.

The main types of bonsai plants suitable for modeling in November are: Luo Hansong, Cuibai, round cypress, velvet cypress, Yanbai, weeping spear, June snow, plum blossom, wax petal flower, oak, Chinese wolfberry, holly, melon seed, yellow poplar, pearl yellow poplar, hammer elm, vertical silk begonia and so on.

For the bonsai pile head which has been suspended with brown rope for 1 to 2 years, when it is found that there are deep constrictions on the stem and branch, the old brown rope can be disassembled in November and the hanging adjustment of the dry branch can be carried out again.

After preliminary root cutting, stem cutting and branch cutting, new tree stumps such as hammer elm, sparrow plum, triangular plum, bayberry, pyracantha and Elaeagnus angustifolia were planted in sandy soil by the method of shallow burial and high culture, and then modeled after branch in the coming year.

After 1 to 2 years of maintenance and modeling, the stumps that have been basically formed can be replanted in November according to the modeling characteristics of stump trunks, roots and branches, equipped with fist stones and covered with moss for indoor display before and after the Spring Festival.

Tall plum piles, Luo Hansong, green peaches, crape myrtle, cypress, tapestry, etc., can be planted in pots in November to strengthen water management and can be used for display in squares, parks and auditoriums in the coming spring.

Flower planting Handbook (December)

Weather characteristics in December: winter has entered in most parts of our country this month, and the weather is getting colder. The snowfall in China has increased from north to south, the temperature in Jianghuai and Jiangnan has dropped to below zero one after another, and the frost is frequent. The maintenance of flowers and trees this month should pay attention to three aspects: first, to do a good job in the heat preservation and anti-freezing of flowers and trees in greenhouses, greenhouses and rooms, and second, to do a good job in pruning and cleaning flowers and trees in the open field and fertilizing the fields. The third is to do a good job in the preparation of compost organic fertilizer and preparation of cultivated soil.

I. Flower reproduction

1. Sow seeds. The flower species that can be sown in the greenhouse in December are: big rock tree, asparagus, gentleman orchid, bulbous begonia, cyclamen, winter coral, African chrysanthemum and so on; the flowers and trees that can be sown outdoors or sand hide are: rose (such as Elizabeth), celadon, rich seeds, holly, fire thorns, palms, privet, camphor, lobular privet, disease-free son, heather, wood heather and so on.

Red leaf plum, wax plum (with heel cutting), Spiraea, yellow poplar and so on. Among them, yellow soil should be used for cutting plum blossom and red leaf plum, mixed substrate of rice chaff ash and fine sand 2 ∶ 1 should be used for rose cutting, and general sandy soil should be used for other kinds of cutting, which can be covered with plastic film to keep heat and moisture.

In the greenhouse, African violets can be propagated in leaves; combined with pruning, mulberry, geranium, lotus, epiphyllum, gemstone, stone lotus, purslane, rooting, longevity flowers, golden bracts, shrimp flowers, four seasons begonia, bamboo begonia, Rieger begonia, pearl orchid, jasmine, Longtuzhu, five-colored plum, goose palm wood, Ruixiang, green apple, Zhu Jiao and so on. Using cold room seedbed, gardenia, Jinxin (Phnom Penh) boxwood, ten meritorious services, hypericum, Admiralty, Yingchun, Luohansong, Luohanbai, June snow, firethorn, silver bud willow, three branches and so on can be propagated by cutting. In addition, branches such as Lingxiao, cloves and grapes can be cut for sand storage and cut again next spring.

3. Grafting. Fine varieties of plum blossom, such as bone red and cinnabar, can use the seedlings of apricot, fruit plum and peach sown in the same year in December to dig up the rootstocks and then split or cut them, then plant them on the seedling bed according to a certain row spacing, bury the soil above the grafting site, or even cover most of the grafted ear, pay attention not to infiltrate into the joint when watering, cover the plastic film to keep warm and wet, and then remove the covered plastic film after the scion sprouts in spring. Use the excavated wild rose plant to bud the rose of the superior variety, or use the robust branch segment of the Elizabeth rose variety (10 to 12 cm long) to cut or split the scion of the superior variety at the top, and then sow the grafted Elizabeth ear segment into a loose seedbed. The grafting part can be buried in the sandy soil, do not infiltrate into the interface when watering, cover the plastic film to keep moisture and heat preservation, remove the covered plastic film after the scion sprouts in the next spring, and then cut the binding belt of the joint with a blade after it is completely alive. In addition, it can also be bagged indoors to moisturize the abdomen and connect the red maple.

4. Press the strip. The feasible species of flowers and trees for strip propagation in December are: Luohansong, plum blossoms, camellias, sweet-scented osmanthus, Michelia, pedicel begonia, purple magnolia, snowballs, brocade flowers, gardenia, Yingchun, Admiralty, eight immortal flowers, hemp leaf hydrangea, Qionghua, snow spray, pomegranate and so on.

5. Ramet. The herbaceous flower species that can be propagated in December are: onion orchid, Ophiopogon japonicus, auspicious grass, hairpin, purple calyx, safflower grass, one-leaf orchid, Jian orchid, spring orchid, cymbidium, kidney fern, shoot stem, iris, big leaf Ophiopogon japonicus, along the steps, evergreen, rooting, Guangdong evergreen. The offspring at the base of the ramet cut from the large colored leaf pineapple must be small plants that have grown on the mother plant for three or four months, otherwise the color bands of the cut offspring are easy to disappear, which should be paid special attention.

The species of woody ornamental plants that can be propagated in December are: Phyllostachys pubescens, Hypericum, Ten Gonglao, Begonia, Brown Bamboo, Safflower Spiraea, Golden Finch, Golden Bell, Yingchun, Jasmine, Jasmine, Magnolia, Gardenia, sisal, Phoenix tail Bamboo, Phyllostachys pubescens and so on.

1. Gather seeds. The grass flower seeds that can be harvested in December are generally the species of grass flowers transferred in the greenhouse or cold room, such as a string of red, thousand-day red, marigold, malachite, cyclamen, gentleman orchid and so on. The seeds of Cymbidium should be sown as they are picked.

The main woody ornamental plants that can collect seeds in December are: rose, wisteria, privet, lobular privet, pyracantha, rich seeds, holly, camphor, and heather. After treatment, these seeds are basically required to sprout in sand and can not be sown until the seeds are white in the coming year. Under dry storage, it is easy to lose vitality, resulting in the failure of sowing and breeding in the coming year.

two。 Transplanting and planting. The herbaceous flowers that can be planted in flower beds and flower beds in December are: carnation, kale, pansy, goldfish grass, calendula, daisies and so on. Some grass flowers can also be put in the greenhouse after potting, such as daisies, calendula, goldfish grass, kale, carnation, pansy and so on, which can be used for street display next spring.

In December, most deciduous greening trees and shrubs can be transplant, such as hibiscus, pomegranate, bauhinia, begonia, wax plum, plum blossom, white magnolia, purple magnolia, disease-free son, Luan tree, acacia tree, seven-leaf tree, red leaf plum, cherry blossom, papaya, two Arbor magnolia, crape myrtle, wisteria, Lingxiao, Linden, Liriodendron, red maple, blue peach, Robinia pseudoacacia, etc. On the other hand, the transplanting of evergreen trees and shrubs should be more cautious. the evergreen species that can be transplanted in winter are: privet, sweet-scented osmanthus, palm, Magnolia, camphor, rhododendron, holly and so on. When transplanting, we should first cut the strength of the main shoots and branches and delete most of the leaves. At the same time, we also need to bring large soil balls, the trunk is bound with grass rope to cover the plastic film, the trunk and big branches are cut and sealed with 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.

December can be on the pot of stumps and flowers are: plum, wax plum pile, camellia, tea plum, stick stem begonia, flowering begonia. Put it in the greenhouse, carry on the flower urging treatment, it is expected to bloom during the Spring Festival.

December to potted hyacinth, tulip, red narcissus, etc., continue to put in the shed to urge flowers, can promote its flowering around the Spring Festival.

1. Cold weather. The following ornamental plants can be placed in simple plastic greenhouses with temperature not lower than 0℃ without freezing damage, such as Penglai pine, asparagus, one-leaf orchid, star anise, peach leaf coral, caltrop, kidney fern, palm bamboo, southern bamboo, Michelia, rich seed, fire thorn, camellia, spring orchid, cymbidium, phoenix tail bamboo, Philippine white bamboo, cycad, etc.

Ornamental plant species with overwintering temperature requirements of not less than 5℃, such as Araucaria, Schefflera chinensis, Rubber tree, Jasmine, Whiteflower, Nuccinia, Pocket coconut, Calla lily, Spring feather, Turtle bamboo, Cymbidium, Cymbidium, Belgian rhododendron, Triangle flower, Cyclamen, Primula, Chromatic plum, Kumquat, Dai Dai, lemon, Sargassum, Pelargonium, Fusang, Buddha belly bamboo, etc., can overwinter in double-layer plastic greenhouse. For the species requiring winter temperature not lower than 10℃, such as variegated leaf wood, flower taro, pepper grass, arrowroot, rich bamboo, fish tail sunflower, Brazil iron, rich tree, reticulate grass, pineapple, pink leaf, poinsettia, hybrid cymbidium, dragon tuzhu, golden bud flower, Milan, butterfly orchid, catlan, orchid, South American iron tree, red (green) gem, Oncidium, tiger head orchid, etc., in the double-layer greenhouse with good sealing performance, it should be heated appropriately. In the especially cold time period, From 4 p.m. to 9 p.m. the next day, cover the top of the greenhouse with straw curtains and remove them when the temperature warms up.

For those cold-resistant potted plants, bonsai plant species, such as wax plum, plum blossom, begonia, azalea, pomegranate, elm, finch plum, oak, crape myrtle, wisteria, boxwood, podocarpus, triangular maple, cuibai, garden cypress, red cypress, water myrica rubra, Chinese holly, duijie white wax, etc., at not less than-10℃, generally will not be frozen; encounter particularly cold weather, and then covered with plastic film or soft grass cold.

[page] Whether it is in the greenhouse, greenhouse, or placed in the living room bonsai, potted flowers and foliage, fruit plants, in addition to must maintain the indoor temperature corresponding to it, but also pay attention to ventilation, can be in the highest temperature of the day around noon to open doors and windows to give ventilation, in case of falling leaves, flowers, fruit. In the ventilation, but also must pay attention not to let the cold air directly hit the plant, so as not to have adverse reactions.

2. Watering. Most potted flowers and potted plants placed in greenhouses, greenhouses and rooms are kept moist. If the temperature is too low and too much watering is done, it is easy to cause plant rot. When the temperature rises, water can be increased and appropriate foliar spray can be given.

For potted flowers, plant species that bloom around the Spring Festival, such as camellia, tea plum, Belgian rhododendron, plum blossom, wax plum, melon, primrose, longevity flower, hyacinth, European narcissus, etc., fruit viewing categories such as Dai Dai, lemon, fingered citron, four seasons orange, golden bean, winter coral, rich seed, South Tianzhu, etc., not only should keep the pot soil moist, but also must give foliar spray to facilitate the expansion of flower buds, but also increase the brightness of flowers and fruits.

For most of the foliage plants placed indoors, it is necessary to keep the pot soil moist and spray the foliage, and always keep the foliage clean; for the species of foliage plants that are not very cold-resistant, such as Fendai leaf, Synthecium, arrowroot, variegated leaf wood, silver queen, etc., when the room temperature is close to the minimum temperature limit that they can tolerate, special attention should be paid to controlling the watering amount to ensure that they can safely overwinter.

The watering time in December should be 3 to 4 hours around noon, and the water temperature should be kept basically consistent with the temperature and soil temperature to avoid adverse reactions caused by low water temperature.

For outdoor newly transplanted flowers and trees, regular inspection should be carried out and supplementary watering should be given in time; for transplanted evergreen trees, foliar spray can be properly given around noon to prevent leaf shrinkage and shedding.

3. Fertilization. Most of the potted flowers and trees placed in general greenhouses, foliage plants, bonsai, etc., should stop fertilizing, otherwise it is easy to cause plant rot and death.

For most of the green trees and flowers planted in the ground, such as Begonia, Magnolia, Magnolia, Manglietia, Michelia, Red Maple, Gardenia, Horse chestnut, Cinnamomum, Osmanthus, Chimonanthus, Plum, Cherry, Red Leaf Plum, Sapindus, Albizia, Koelreuteria, Palm, Paeonia, Peony, Admiralty, Hypericum, Grape, Rose, Spiraea, Mandarin Tree, Mountain Plum, Deutzia, Pomegranates, Lagerstroemia, Wisteria, Pyracantha, South Tianzhu, Lilac, Lingxiao, Aucklandia, Hypericum, Salix, Cryptomeria, Cedar, cypress, dragon claw locust tree, elm leaf plum, plum, white silk plum, heather, bauhinia, hibiscus, etc., in December, when the garden is plowed, fertilizer can be buried on the periphery of the plant root system, such as cake fertilizer, pig dung, pond mud, septic tank residue, etc., laying a good material foundation for next year's growth and flowering.

For potted flower species placed indoors at 10℃ to 15℃, such as camellia, tea plum, azalea, plum blossom, wax plum, golden bud flower, shrimp flower, pineapple, daphne, melon, primrose, cyclamen, begonia, hyacinth, clivia, tulip, freesia, etc., 1.2% potassium dihydrogen phosphate solution can be continuously applied to promote bud pregnancy and flowering of plants.

4. Trim. Hedgerows, green walls and ball shapes that have not been pruned in November shall be pruned. Hedgerows and green walls such as Ligustrum lucidum, Ligustrum microphylla, Echinacea, Euonymus chinensis, Chinese cypress, etc.; balls such as Chinese holly, Chinese bayberry, Chinese heath, Buxus chinensis, Pittosporum chinensis, Golden bell, Pyracantha chinensis, Dragon cypress, Juniperus chinensis, etc. shall be fertilized while pruning.

For the ground flowers and trees that have not been pruned in November, such as rose, crape myrtle, palm, red leaf plum, heather, paulownia, plum blossom, wax plum, etc., plastic pruning can be carried out. After pruning, fertilizer can be buried around the root system.

For the bonsai plant species dominated by pruning, such as elm, plumule, Chinese holly, Fujian tea, triangular maple, oak wood, white wax, fire thorn, June snow, Podocarpus, cypress, juniper, begonia, papaya, etc., continue to prune in December to lay a good skeleton for next year's growth; for the plants that have not been replaced for many years, they can be replaced in combination with pruning.

5. Pest control. For grape, begonia, rose, rose, camellia, Lagerstroemia and other flowers and trees whose leaves are prone to diseases and insect pests, the dead leaves under the plants will be collected and burned, which can reduce the occurrence of diseases next year. At the same time, stone sulfur mixture is sprayed for sterilization and disinfection.

For powdery mildew of potted melon and gray mold of primula, 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 greenhouses, such as Dai, fingered citron, cycad, camellia, monophyllum, etc., you can wipe them with rags first, and then use pesticides such as rapid killing to control them.

When be opposite aerate bad, the flowers and trees kind that often appears aphid on potted plant, wait like Bai Lan, Milan, Dai, rose, Fujian tea, usable tobacco water undertakes control.

For many kinds of scale insects that often appear on the trunks and branches of flowers and trees such as Pittosporum, Osmanthus fragrans, Phalaenopsis, Camellia, Ligustrum lucidum, Pyracantha, Oleander, Begonia, Magnolia, Bauhinia, Gardenia, Cedar, Photinia, Lagerstroemia, Chimonanthus praecox, etc. cultivated in the open field, such as Ceratococcus hornatus, Japanese wax scale, red wax scale, shield scale, arrowroot scale, mealybug scale, etc., spray them with high concentration of pesticides such as Sukill, Quinethiuron, Pushiling, etc., and rarely cause phytotoxicity.

6. Compost fertilizer. In order to breed seedlings next year, the preparation of culture soil needs, can use winter leisure time, rapeseed cake, bean cake, tea seed cake, etc., into the water tank, pool, add water for sealed maceration fermentation.

Dry withered grass, deciduous leaves, shrubs, branches, etc. will be stacked with the garden soil layer, ignited and burned to form burning soil, which is the best covering soil for planting seedlings next year.

The manure, pond mud, chicken manure and pigeon manure mixed with garden soil, sealed fermentation, can be used for the next year's nursery topdressing and preparation of culture soil.

7. Preparation of culture soil. Use your free time in winter to find an open space or under the shade of trees and pile as much culture soil as possible for the next spring when you need to change pots and plants. Generally, it is 4 parts of garden soil, 2 parts of rotting leaf soil (or 2 parts of mountain humus soil), 1 part of fine sand, 1 part of sawdust, tobacco powder or chaff ash, plus about 5% of retting cake fertilizer and 2% to 3% compound fertilizer. Among them, garden soil and rotting leaf soil should be sieved to sift out stones, roots and other impurities. After fully mixing them, they can be covered with plastic film. They can also be stacked indoors. After 3 to 4 months, they can be used for changing pots or putting flowers in pots.

8. Turn over the ground and freeze the soil. For the garden used for sowing, cutting and planting seedlings next year, ploughing can be carried out in December; for the garden used for sowing and planting seedlings, cake fertilizer, manure, pond mud, etc. can be applied before ploughing; temporarily do not make beds, after winter freezing, to the early spring of the next year to draw ditches as beds, can greatly reduce the cost of seedling management, but also reduce the occurrence of diseases and insect pests.

Ornamental plant species suitable for bonsai modeling in December are: Podocarpus, Arhat cypress, Park cypress, Cuibai, Ficus cypress, Platycladus orientalis, Pudibai, True cypress, Black pine, Five-needle pine, Red pine, Myrica rubra, Chinese holly, Euonymus pendula, Ginkgo biloba, June snow, broom, elm, larch plum, Acer triangularis, wax petal flower, Tamarix chinensis, Malus acuminata, Malus papaya, Melon seed, Buxus chinensis, Wisteria, Lagerstroemia, Ficus, Fujian tea, Fraxinus chinensis, Quercus mongolica, etc.

For bonsai plants fixed by palm wire (rope) or metal wire, if the fixation time has been one year, or obvious constriction marks are found on the trunk and branch, the original binding should be removed, and the metal wire or palm rope should be used again for hanging traction.

After some necessary pruning and shaping, the plum piles, podocarpus, begonia, ginkgo, juniper, crape myrtle, etc. that have been planted in the ground are planted in suitable pots, and the management is strengthened so that they can be displayed in public places or rooms in the coming year.

Winter for some shallow pots of landscape bonsai, tree stump bonsai, must be carefully managed, one is to prevent the pot soil frostbite plant roots, two is to prevent the freezing of artificial cemented rocks disintegration, three is to prevent the plants planted on rockery were frozen to death or dry. It can be placed in a place that is not frozen, and regularly watered and sprayed, so that it can safely winter.

The seeds of mature winter corals can also be sown indoors at this time. In January, seeds such as NanTianZhu, Pyracantha, Holly and Fugui seeds can be picked, and after treatment, they can be stored in sand for germination, and can be sown only after the seeds are cracked and 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 there is mildew, the seeds must be poured out and washed again, and clean fine sand must be replaced before storage; If the seeds are found to be dry, supplementary water spray should be given in time; If the seeds are found to have been cracked or the radicle has been extended, they must be sown immediately, and covered with plastic film or straw, pine needles, etc. for heat preservation and moisture preservation.

II. transplanting

January, in not too cold areas can be transplanted planting grass flowers are: Dianthus, collard greens, calendula, daisies, etc.; in relatively cold areas, Dianthus, collard greens, snapdragon, pansy, primrose, etc. can be planted in pots, first placed in simple plastic greenhouses, and then used as street flower beds, green spaces and flower displays after spring warms up.

In January, most deciduous shrubs and greening trees can be transplanted and planted, such as hibiscus, pomegranate, bauhinia, begonia, ginkgo, sweet gum, maple, wintersweet, plum blossom, magnolia, purple magnolia, sapindus, koelluteria tree, acacia tree, horse chestnut, red-leaf plum, cherry, papaya, magnolia, crape myrtle, wisteria vine, creeper, linden tree, mandarin tree, peach, Chinese tallow, safflower spiraea, triloba, rose, sophora japonica, dragon claw locust, etc. Evergreen tree species, especially camphor, green law, etc., this month in addition to special circumstances, generally should be advanced to December or delayed to February and then transplanted, of course, in sheltered places, after transplanting intensity shrinkage shear, and strengthen the cold and watering management after transplanting, there is no problem.

In January, although the weather is cold, it does not affect the collection of wild stumps in the process of forestry afforestation in the south of the Yangtze River, mainly deciduous stumps, such as elm, larch plum, triangular maple, azalea, Lagerstroemia, Acer claustrophala, Wisteria, Chimonanthus praecox, wild plum, Elaeagnus, Euonymus pendula, etc.; evergreen stumps, such as southern Tianzhu, cat thorn, Chinese holly, holly, oak tree, etc., must be cut intensively and most leaves must be deleted. Whether deciduous stumps, or evergreen tree stumps, should be adopted shallow buried high culture method cultivation, and covered with straw curtain anti-freezing.

III. cold-proof

This month's cold-proof heat preservation work is the most important in the management work. A slight negligence will bring serious losses to potted flowers and bonsai overwintering. According to the lower limit of the lowest temperature that different flower species can endure, a special environment for safe winter should be created, either in greenhouse, in greenhouse, in home, or buried in open soil. In a simple plastic greenhouse with a temperature of not less than 0℃, ornamental plant species that can withstand low temperatures of about 0℃ can be placed, such as Penglai pine, asparagus, one-leaf orchid, star anise, caltrop, kidney fern, palm bamboo, southern sky bamboo, peach leaf coral, Michelia, spring orchid, orchid, rich seed, daphne, cycad, calamus, phoenix tail bamboo, Philippine white bamboo, etc. In the double-layer plastic greenhouse not lower than 5℃, ornamental plant species that can endure low temperature of about 5℃ can be placed, such as araucaria, rubber tree, jasmine, pearl orchid, white peony, pocket coconut, bottle orchid, calla lily, spring feather, turtle, kumquat, Dai Dai, lemon, Sanwei sunflower, camellia, tea plum, orchid, primrose, epiphyllum, arrow-shaped lotus, big buddha belly bamboo, Belgian azalea, triangular plum, five-colored plum, etc. In the double-layer plastic greenhouse or greenhouse with auxiliary heating equipment, flowers and plants that can endure low temperature of about 10 DEG C can be placed, such as variegated leaf wood, flower arrowroot, fruit arrowroot, pineapple, pepper grass, colored leaf grass, rich bamboo, fish tail sunflower, Brazil iron, fortune tree, reticulate grass, red (green) gem, green giant, green king, silver queen, Milan, cymbidium, phalaenopsis, katlan, oncidium, wandai orchid, money tree, South American iron tree, desert rose, pink leaf, poinsettia, Golden bud flower, coral flower, etc., in the particularly cold time period, from 4 p.m. to 9 p.m. the next day, it is advisable to cover the grass curtain on the top of the greenhouse until the temperature warms up before stopping covering the grass curtain. In very cold days, we should strengthen the inspection of heating facilities and personnel on duty, especially from 5 to 6 o 'clock in the morning, and must not cut off fire or power failure, otherwise it is easy to cause freezing damage to plants. For those relatively cold-resistant potted flowers, potted plant species, such as wax plum, plum blossom, begonia, azalea, pomegranate, elm, finch plum, oak, crape myrtle, wisteria, boxwood, podocarpus, triangular maple, cuibai, juniper, summer cypress, Platycladus orientalis, small bayberry, holly, Chinese white wax, etc., can be buried together with the flowerpot in the soil, when not lower than-10℃, generally will not occur frost damage, in the event of particularly cold weather, and then covered with plastic film or soft grass insulation.

It is worth noting that, whether placed in the greenhouse, greenhouse, or home potted flowers or bonsai, including fruit, leaf plants, in addition to maintaining the temperature appropriate to it, but also should do a good job of ventilation, can be in the highest temperature of the day around noon to open doors and windows to give ventilation, to prevent the occurrence of falling flowers, leaves, fruit. When ventilation is given, it is also necessary to avoid direct cold air blowing on the plants.

In January, special attention should be paid to the greenhouse and greenhouse inspection during each cold air southward process. If glass damage and film tear are found, leakage plugging shall be made up in time to avoid freezing of potted flowers. In the greenhouse to provide coal, gas, oil heating, should also be carefully checked, do not have air leakage, smoke leakage into the greenhouse or greenhouse, in case of smoke damage caused by falling flowers, leaves, fruit.

In order to promote peony flowering during the Spring Festival, potted peony can be placed in a greenhouse, heated to 18 ° C to 25 ° C during the day, maintained at about 10 ° C at night, and increased by 4 to 5 hours of light (incandescent lamp) every day. It is expected to bloom around the Spring Festival. Potted plum blossoms, wax plum blossoms, camellia, tea plum blossoms, flowering crabapple, flowering crabapple, spring jasmine, etc. can also be placed in a greenhouse at about 15 DEG C for flower promotion, and the illumination time can be appropriately increased, which can meet the needs of indoor display of potted flowers and trees during the Spring Festival. Water and fertilizer management should be strengthened for potted hyacinth, tulip, narcissus and freesia placed in greenhouse in December, and it is expected to be used as decoration display during Spring Festival. [page]

IV. watering

In January, the watering management of potted flowers, the first and most important thing is to pay attention to the temperature of irrigation water, that is, to keep the water temperature and soil temperature generally consistent, if the disparity between the two is too large, it is easy to cause adverse reactions of potted plants, and even make plants fall, rot or die. Watering time, preferably arranged around noon 2 to 3 hours. Secondly, according to different plant species, determine the number, frequency and method of watering, most potted flowers and bonsai placed in greenhouses, greenhouses and living rooms should be kept moist, the temperature should be reduced accordingly, and when the temperature rises, the amount of watering can be increased and foliar spray can be given. For most of the foliage plants, it is necessary to keep the pot soil moist, but also pay attention to spraying the leaves, always keep the leaves of the plants clean, for the less cold-resistant foliage plant species, such as Fandai leaves, Synthecio, arrowroot, variegated leaf wood, etc., when the temperature is close to the minimum temperature that the plant can tolerate, the watering amount should be specially controlled. For those potted flowers that will bloom around the Spring Festival, such as camellia, tea plum, Belgian rhododendron, poinsettia, melon, wax plum, plum blossom, primrose, hyacinth, longevity flower, calendula, etc., fruit observation such as firethorn, Dai, fingered citron, lemon, rich seed, kumquat, golden bean, winter coral, etc., not only keep the pot soil moist, but also spray water on the plants to facilitate the expansion of flower buds, but also increase the bright color of fruits.

Although potted flowers do not need much water in January, they should be checked to prevent water shortage in potted flowers placed in remote parts, and timely watering of plants dried in pot soil can reduce the death of overwintering plants.

For newly planted greening trees and flowering shrubs, regular inspection should be carried out and supplementary watering should be given in time, especially for those evergreen ornamental plants after transplantation, leaf spray should be properly given around noon to prevent leaves from shrinking and falling due to excessive air.

v. fertilization

For most of the green trees and flowering shrubs planted in the field, such as begonia, magnolia, Michelia, acer, gardenia, horse chestnut, camphor, linden, crape myrtle, lingxiao, osmanthus, wintersweet, plum blossom, podocarpus, cherry blossom, sapindus musifida, acacia, koeluteria, palm, schima superba, nannan, purple tree, camptotheca, peony, golden bell, boxwood, grape, coral tree, rose, hydrangea, red-leaf plum, plum, trifoliate plum, mandarin tree, Deutzia, Mountain plum blossom, banksia rose, Elaeocarpus sinicus, golden willow, weeping elm, Cryptomeria, Taiwan fir, cedar, Chinese sophora tree, Chinese locust tree, white sericeous plum, hibiscus, clove, Lagerstroemia, Heather, bamboo, purple bamboo, pomegranate, loquat, etc. If the fertilization task is not completed in December, cake fertilizer, manure, pond mud, septic tank cleaning matter, etc. can be buried on the periphery of tree roots while ploughing, so as to lay a good material foundation for spring growth and flowering.

For potted flowers placed in greenhouses at 10℃ to 15℃, such as Belgian rhododendron, shrimp flower, golden bud flower, daphne flower, melon, primrose, cyclamen, red narcissus, flowering crabapple, hyacinth, tulip, multicolored pineapple, clivia, Stagelanthe, crab claw orchid, etc., low concentration of potassium dihydrogen phosphate solution can be continued to be applied to facilitate the growth of plants and flowering of pregnant buds.

For most of the potted flowers and trees placed in the greenhouse, foliage plants, bonsai, etc., due to winter plants in a dormant state, fertilization should be stopped, otherwise it is easy to cause the rotten roots of the plants to die.

vi. pruning

The hedgerows, green walls and balls that have not been pruned in December are continuously pruned; the flowering shrubs that have not been pruned in December, such as rose, crape myrtle, banksia rose, Chinese creeper, wisteria vine, flowering rose, camphor tree, Chinese tung tree, Chinese tallow, heather, pomegranate, red-leaf plum, papaya, wintersweet, plum blossom, palm, grape, etc., are continuously pruned; after pruning is completed, base fertilizer is buried at the periphery of the root system to meet the needs of spring growth.

For the potted plant species with pruning as the main method and binding as the auxiliary method, such as elm, finch plum, triangular plum, Fujian tea, oak wood, white ash, water myrica rubra, elaeagnus, fire thorn, June snow, juniper, etc., we can continue to adjust and prune according to the original composition requirements, the development trend of dry branches of plants, according to personal aesthetic taste, and lay a good foundation for the growth and formation of spring. At the same time as pruning, plants that have not been repotted for many years can be repotted.

VII. bingchong prevention

For Begonia, Plum Blossom, Ulmus Leaf, Papaya, Loquat, Peach, Cherry Blossom, Red Leaf Plum and other trunk or large branches, which have been eaten by Pink Neck Longicorn, etc., they can be sawn off and burned.

Cleaning leaves under roses, roses, grapes, crape myrtle and other trees, gathering and burning them together can reduce the occurrence of leaf diseases in the coming year.

The large-scale occurrence of scale insects in the current year can be effectively inhibited by spraying with high concentration of quickkill, quinphos, diaphorous phosphorus and stone sulfur mixture on horny wax scale, turtle wax scale, red wax scale, blowing cotton scale, shield scale, arrowhead scale, mealyscale and line scale appearing on the trunks and branches of Pittospora chinensis, Pittospora chinensis, Ligustrum lucidum, Pyracantha fortunei, Fructus Gardeniae, Plum Blossom, Chimonanthus praecox and Heather.

Thiophanate-methyl can be used to control powdery mildew on melon and gray mold on primula leaves in greenhouse to prevent them from spreading to other plants.

The scale insect and coal pollution disease appeared simultaneously on the plants of Dai, fingered citron and kumquat in greenhouse were comprehensively controlled. The coal pollution patches on the leaves and the insects attached to the dry branches were wiped off by wet cloth, and then the pesticides such as dimethoate were sprayed for control.

The grey mold on cyclamen plants in greenhouse can be controlled by spraying 50% iprohydantoin (main component is iprodione) WP 1000 - 1500 times.

VIII. compost

Rapeseed cake, bean cake, tea seed cake, etc. are poured into a pool or water tank for soaking and fermentation so as to be used for watering potted flowers in growing season; withered grass, branches, fallen leaves, etc. are stacked in layers with garden soil, ignited and burned, and self-made burning soil can be used as covering soil for seeding and seedling raising in spring; manure, pond manure, tobacco powder, chicken excrement and pigeon dung are mixed with garden soil for composting and fermentation, and can be used as fertilizer for preparing culture soil.

IX. ploughing and freezing

For the nursery land that has not been cultivated in December, it can be tilled in the first ten days of January. At the same time, cake fertilizer, compound fertilizer, soil fertilizer, etc. can be applied. After winter freezing, the furrow can be used as bed in early spring for sowing and planting seedlings.

Because January is particularly cold, suitable for modeling plant species must be those with soft branches, good toughness, easy to model operations, such as Podocarpus, Cuibai, Ginkgo biloba, Buxus chinensis, Ficus chinensis, Sabina chinensis, June snow, cypress, cypress, pine needles, Huangshan pine, black pine, water myrica rubra, cytiscus, wax petals, Euonymus pendula, fig tree, wisteria, etc. After modeling, it is best to put the plant indoors or in a simple plastic shed, and then move it outdoors after the spring is warm, which is conducive to the healing of the damaged parts that may be caused during modeling.

For the plants molded with palm rope or metal wire 1 to 2 years ago, if there are obvious concave constrictions in the binding position, the original binding should be removed and re-tied.

In January, we should strictly strengthen the management of some shallow potted tree stump bonsai, shallow potted landscape bonsai and small and miniature bonsai. Small, miniature bonsai, should be buried in the indoor sand bed; tree stump bonsai to prevent the pot soil from freezing, damage to the hairy roots of the plant, and can lead to the disintegration of man-made cemented rocks, but also to prevent the plants planted on small stones from dying after freezing, they should be placed in a non-freezing place, and regularly watered and sprayed to ensure that they can safely winter.
