Key points of Cuttage Propagation of Corydalis

Evening incense is a special ornamental flower. Flower friends who like it all know that it has a certain ornamental value and medicinal value. If some flower lovers want to breed their own nocturnal incense, they might as well consider the method of cutting propagation.

Night incense

1. Choose the insert. The branches with strong growth and free of diseases and insect pests should be selected, and the sunny branches in the middle and upper part of the year should be selected on the same plant, requiring short internodes, strong branches and leaves, full bud tips, and unsuitable branches and overgrown branches that are about to bloom.

2. Select the matrix. The bed soil prepared with peat soil and rotten leaf soil is 3 ∶ 3 ∶ 4 respectively. The bed soil prepared in this way has the characteristics of increasing bed temperature, water retention, aeration, fertility and partial acidity, and is suitable for branches to take root and sprout.

3. Deal with cuttings. The cuttings were treated with ABT rooting powder before cutting, which had the effect of promoting rooting. Cut the cuttings into a section of 8 cm to 12 cm, with 2 to 3 buds above. The cut in the lower part of the cuttings should be 0.5 cm below the node. The incision should be smooth, cut off the lower leaves, leaving only 2 to 3 leaves at the top, and the insertion depth is generally about 3 cm.

4. Conditions for rooting. The suitable rooting temperature is 20 ℃ to 24 ℃, and the soil temperature is 3 ℃ to 5 ℃ higher than the air temperature. The relative humidity of the bed air is 80% to 90%, which is favorable for rooting and requires light of about 30%. The moisture should be suitable, which is slightly higher at the initial stage of cutting and slightly dry at the later stage. The suitable period for local open-field cutting is from early May to mid-June, which is in a better climate, which can better meet the temperature and humidity conditions needed for cuttings to take root.

5. Strengthen the management after insertion. After planting, it should be watered thoroughly, covered with plastic film, placed in a shaded place, or scattered grass on the film to prevent direct sunlight, and increase light at night to help the cuttings survive. Air is released once or twice a day to replenish the oxygen needed and prevent diseases. To often spray water, keep the inserting bed moderately moist, but do not spray too much water, otherwise the inserting bed is too wet, often affecting the cuttings healing and rooting. When the new root grows to 2 cm to 3 cm, it can be transplanted into the basin at the right time.

Evening primrose and its cultivation techniques are perennial vines, distributed in Yunnan, Guangxi, Guangdong and Taiwan. They are semi-wild vegetables with fresh flowers and buds for consumption. It has the effect of clearing the liver and eyesight, and can treat red swelling and pain of the eyes, measles on the eyes, corneal nebula and so on.

I. characteristic characteristics

Nocturnal incense has more developed root system and more lateral roots. Stems trailing, without tendrils. Leaves simple, opposite, long ovoid to broadly ovate, green. Cymes with pale yellowish green flowers. The fruit is pod, lanceolate-cylindrical, apically acuminate. Seeds broadly ovate, apically with white sericeous seed hairs.

Nocturnal incense grows mostly in woodland or bushes. Like warm, humid, sunny, well-ventilated, loose and fertile soil, drought-resistant, barren, not waterlogging, not cold-resistant, stop growing after defoliation in winter; branches and long leaves after spring, with axillary buds or flower buds in each node, lateral branches and inflorescences continue to occur with growth, generally blossom one after another from May to October, and smell fragrant when flowering, more fragrant at night. Winter results.

2. Key points of cultivation techniques

1. The method of reproduction. Cuttings, striping, ramet or seed can be used to raise seedlings. Cutting propagation is often used. Semi-lignified and robust stem vines are selected in winter and spring, and stem vines with about 30cm and 5 nodes are cut for cuttings, and seedlings are raised in the seedbed or planted directly in the field. Ramet propagation is only suitable for plants with more lateral branches near the ground. Nocturnal incense bears little fruit and generally propagates without seeds.

two。 Planting, management and harvesting. Planting in spring and summer, select the plot with good drainage, apply sufficient basic fertilizer to raise the border, 30cm, row spacing 1.0m-1.5m, plant spacing 50~70cm. Open a hole in the border, put the seedlings obliquely in the hole, cover the soil, the seedlings are exposed to the ground, cover the border with a layer of dry weeds and sprinkle with water. Just keep the soil moist in the future. When the seedlings grow to 1m, set up to draw the vine. The way of setting up the frame is similar to planting melons and beans, leaving 2-3 main vines per tree when introducing vines, and the redundant ones are removed. Pick the whole inflorescence when 40% to 50% of the florets are budding and a few flowers are blooming. Generally pick once a day, blooming flowers should be removed, so as not to affect other buds and lose commodity value. Night fragrance generally produces 1200~1800kg per 667m2.

3. Fertilize. After clearing the garden in the first ten days of March every year, shoot-promoting fertilizer was re-applied once, and compound fertilizer 25kg, mature organic fertilizer (soil fertilizer or farm manure) 200~300kg were applied every 667m2 to cultivate soil and cover fertilizer. After every 20-30 days, every 667m2 was drenched with compound fertilizer aqueous solution 15kg or rotten farm manure 500kg, soil cover fertilizer, do not partial application of nitrogen fertilizer.

4. Pest control. At present, it is found that the main pests are mites and shellfish, and the disease is Fusarium wilt. In order to control mites, we can use anti-mite 23 EC 800x solution, 73% mites 2000 times solution and so on. To control shell insects, you can use 40% dimethoate emulsion 600-800 times. To control Fusarium wilt, we can use 600 times of Fusarium wilt 600 times, 50% carbendazim 600 times, and so on. If you find a wilted plant, you should remove it in time, take it outside the garden and burn it, and spread quicklime in the soil around the diseased plant, and replant it one month later.

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 bully" 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 section on the stump can be treated with stone sulfur mixture, etc.

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 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, wild rose as rootstock, Chinese rose as rootstock, and Artemisia annua as rootstock to propagate fine varieties of chrysanthemum. The two-year-old seedlings of Chimonanthus praecox are used as rootstock, and the excellent variety of Chimonanthus chinensis can also be grafted with potted rootstocks. In addition, cactus and trigonous arrow can be used as rootstock to propagate crab claw orchid by grafting.

4. Pressing strip

The flowers and trees that can be propagated under high pressure in May are: Magnolia, rubber tree, Milan, rhododendron, camellia, variegated wood, Michelia, red maple, etc.; flowers and trees that can be propagated under low pressure are: plum blossom, wax plum, rose, gardenia, Luohan pine, sweet-scented osmanthus, Lingxiao and so on.

2. Potting and transplanting

1. Upper basin

Most of the potted flowers used for street decoration during the National Day must be planted in May. After three to four months of careful maintenance, they can blossom on time at the end of September and the beginning of October, so as to create a festive, warm and colorful atmosphere. The main species are: a string of red (pink, white, purple), thousand-day red (white), cockscomb, hundred-day red, sulfur chrysanthemum, chrysanthemum, ground skin, marigold, Longkou flower, Tianmeng, he's impatiens, colored leaf grass, begonia and so on.

two。 Transplant

At the end of April and the beginning of May, when Magnolia Magnolia was transplanted from the end of April to the beginning of May, the survival rate was the highest. Some flowers and trees that germinate late and are easy to survive can also be planted with soil balls in early May, such as crape myrtle, hibiscus, bauhinia, pomegranate, acacia and so on.

III. Flower management

1. Watering

Due to the rising temperature, the water demand of potted ornamental plants will gradually increase. In addition to paying attention to the combination of root watering and foliar spraying, we must also pay attention to the quality of water used for watering and spraying, and it is best not to use tap water directly. In particular, do not directly use tap water treated with bleach. To this end, tap water can be first injected into a pool or small tank, and then an appropriate amount of acidified substance is added to improve the acidity of water quality, such as ferrous sulfate, whose concentration can be controlled between 0.1% and 0.2%. The main species of potted flowers suitable for acidic water quality are camellia, tea plum, plum blossom, rhododendron, Yingshanhong, gardenia, Ruixiang, magnolia, chrysanthemum, begonia, safflower oil tea, etc.; foliage species are: iron tree, spring feather, tortoise back bamboo, palm bamboo, rubber tree, fern, Luohan pine, variable leaf wood, red (green) gemstone, hulk, green emperor, synthetic fruit taro, bamboo taro, pineapple, Brazilian wood, rich tree, goose palm wood, etc. Fruit categories are: daidai, firethorn, kumquat, bergamot, lemon, southern bamboo, winter coral, rich seeds and so on.

two。 Pruning, picking buds

(1) pruning the shearing of white orchids shortly after leaving the room, special attention should be paid to the loose pith of its branches, and the cross section is easy to lose water and dry up and extend downwards. For this reason, consideration should be given to cutting 8 to 10 centimeters above the bud eye, not too close to the bud eye. Pruning after potted rose flowers should be moderately reduced by 10 to 20 centimeters, and the bud eyes located in the middle of the branches can give birth to flower buds.

(2) picking buds for potted Chimonanthus plants, we should also pay attention to the position of picking buds, generally 3 to 5 centimeters above the selected leaf buds, otherwise they will wither and atrophy because of the wound, which will affect the selected leaf buds downwards. For the rose on the basin in the same year, the terminal buds should be removed in time to promote the formation of a good plant shape.

3. Shade

After entering May, potted plants that like semi-shade or shade should be moved under the shade or in the shade, such as: tortoise back bamboo, brown bamboo, taro, spring feather, hulk, red (green) gemstone, green emperor, pink daiye, sunflower, taro, orchid, rhododendron, crane orchid, camellia, tea plum, etc.; flowers and trees that like light must be given full light, such as wax plum, iron tree, rose, pyracantha, jasmine, magnolia, etc. Bonsai plants, such as hammer elm, sparrow plum, triangular maple, bayberry, oak, June snow, black pine, cotton pine, etc., require sufficient light, while Luohan pine, tiger thorn, Chinan, Cuibai, five-needle pine and so on can be shaded appropriately.

4. Fertilizer application

To Camellia, rhododendron, tea plum, plum blossom, Milan, jasmine, white orchid, gardenia, wintersweet, rose, Ruixiang, gentleman orchid, orchid, begonia, etc.; to pick off the residual flower stem after the flower fade, and to apply nitrogen-based and phosphorus-supplemented compound fertilizer once every semimonthly to lay a good foundation for its pregnant flower buds while restoring its vegetative growth. For foliage-based species, such as rubber trees, tortoise-backed bamboos, hulks, red (green) gems, green emperors, spring feathers, orchids, ferns, etc., the fertilizer and water of thin pancakes are applied once every half month. For foliage plants with colored spots and patterns, such as Phnom Penh tiger tail orchid, colorful pineapple, golden heart Brazilian wood, variable leaf wood, colored leaf taro, white butterfly taro, pink leaves, etc., 0.2% potassium dihydrogen phosphate solution can be applied outside the root to make the leaf color look more beautiful and bright.

5. Pest control

For roses, etc., we should pay attention to the control of powdery mildew and brown spot, timely spraying pesticides to kill leaf-eating pests, and to common leaf-eating pests such as daidai, kumquat, golden bean, bergamot, lemon and rue. Citrus butterfly larvae should be killed by spraying as soon as possible.

Fourth, bonsai modeling

The ornamental bonsai plants that can still be modeled in May are: plum blossom, lobular gardenia, mountain gardenia, Luohansong, June snow, emerald cypress, bayberry, Galo wood, ginkgo and so on. It is worth noting that: modeling must be careful, try not to hurt the branches and bones, otherwise it will affect the normal growth of plants.

Flower planting Handbook (June)

The weather characteristics of June: from time to June, the temperature rose further. The Yangtze-Huaihe River Basin has entered the Meiyu season, entering the plum on June 12 and coming out on July 7 this year, when the evenly matched cold and warm air met in the region, causing frequent frontal or cyclone activities. June is the season with the largest number of Rain Water of the year, with long periods of continuous rainfall. Special care should be taken for some dormant or semi-dormant flowers and most bonsai in summer, so as not to cause rotten roots due to Rain Water, or plant growth due to lack of light, disturbing the shape or affecting the normal flowering and fruiting of ornamental plants. The main contents of raising flowers from south to north in June are as follows:

I. Flower reproduction

1. Sowing seeds

The flowers and trees that can be sown in June are: primrose, lotus seed, cycad, loquat, wax plum and so on. For Chimonanthus praecox, when the pot-shaped fruit sac on the fruiting mother tree changes from green to yellow, and then from yellow to brown, the internal seeds are brown; peel off the fruit sacs in time, remove the seeds, soak them in cold water for 24 to 36 hours, wait for the seeds to absorb enough water to expand, and then bury them in clean wet sand to sprout. After about 2 weeks, the seeds can be split and sown in a ditch. The thickness of the covered soil is generally 2 cm to 3 cm, covered with straw to moisturize. After the cotyledons of most seeds are unearthed, remove the grass for 2 to 3 times and build a shed for shade in time.

two。 Cuttage

In summer, the temperature and humidity are high, and the cambium in the branches of flowers and trees is active, which is the best time for cutting to propagate flowers and trees. There are two kinds of flowers and trees suitable for softwood cutting in summer. One is the species of hardwood cuttings that are not easy or slow to take root, such as sweet-scented osmanthus, camellia, Michelia mollissima, medlar, holly, clove, magnolia, tapestry, snowball, Qionghua, coral tree, paulownia, Belgian rhododendron, Buddha belly bamboo (root with air), rubber tree, metasequoia, pond fir, Sequoia lanceolata, etc. The other is the species that are easier to take root. Such as yellow poplar, rose, fiery thorn, golden bell, welcome spring, Jasmine, June snow, pomegranate, hibiscus, golden Finch, jasmine, pearl orchid, dragon leaf bead, five-colored plum, Diitang, leaf flower, bergamot, lemon, Luohansong, southern bamboos, Lingxiao, red back cinnamon, honeysuckle, Fusang, plantain, hypericum, honeysuckle, golden willow, dragon claw willow, banyan, Brazilian iron, cinnabar root, incense, changing leaf wood, Shu Shu, mountain plum, crape myrtle, banyan tree Sea immortal, brocade flower, hemp leaf hydrangea, peach coral, goose palm firewood, ten meritorious categories, star anise gold plate, snowspray, eight immortal flowers, poinsettia and so on. It also includes a large number of other grass flowers, such as five-clawed golden dragon, brocade, golden lotus, piano Finch, Qianqiu tea, perfume grass, dry umbrella grass, geranium, colored leaf grass, begonia, tricolor pansy, thousand-day red, hundred-day red, malachite, marigold, sulfur chrysanthemum and so on.

Take the fully closed moisturizing cuttings of camellia and sweet-scented osmanthus as an example: the cutting time is from early June to mid-July, when the twigs of sweet-scented osmanthus and sweet-scented osmanthus are semi-lignified, and the substrate can be yellow soil, sandy soil or vermiculite. Cuttings are new shoots of the year, 10 cm to 15 cm long, leaving only 2 to 3 leaves at the end. Dip the lower incision with 500mg / kg 1#ABT rooting powder or naphthalene acetic acid solution for 10 seconds, dry slightly and insert it into the seedbed. The depth of the cuttings is 1x2 to 2x3, and the row spacing is 2cm × 8cm. After pouring water, set up a bamboo bow on the seedbed, then cover it with plastic film, press it tightly with mud around, shade the light in a double-layer shade, keep the bed moist, control the temperature in the film at about 30 ℃, and keep the humidity above 90%. Generally, a large number of cuttings can take root after one month.

3. Grafting

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

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

The plant species that can be modeled in June are mainly woody ornamental plants with strong adaptability and resistance to prickling, and they must be pots or ground-planted plants in early spring. They are: Luo Hansong, Yingchun, Elaeagnus angustifolia, Huashan pine, Cuibai, round cypress, wolfberry bone, holly, Chinese wolfberry, five-needle pine, weeping silk begonia, Xifu begonia, plum blossom, green peach, triangular maple, June snow pine, melon seed yellow poplar, hammer elm, Tamarix, water bayberry, real cypress, ginkgo, snow willow, firethorn and so on. June modeling must be careful, light and slow, must not be too hasty, too hard.

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

Flower planting Handbook (July)

July weather characteristics: July 7, Jianghuai area ended plum rain weather. July 16 into the volts, August 15 sunrise volts, most parts of the country into the hottest period of the year. The average monthly temperature in July in most parts of China is above 24℃, 28℃ in the south of Jianghuai, and only the average temperature in July in the north of Northeast China and Qinghai-Tibet Plateau is below 20℃. July flower management mainly includes the following contents: 1. Flower reproduction 1. sowing July feasible sowing grass flowers are: melon, primrose, collard greens, bluebells and so on. When sowing, attention should be paid to moisture, shade and increase ventilation and light transmission.

In addition, some flowers and trees can be propagated by water insertion in July. They are: gardenia, oleander, rose, jasmine, pearl orchid, fig, pomegranate, fuchsia, crape myrtle, hibiscus and so on. The use of water insertion method to propagate flowers and trees, one is to have a thick 1 cm to 2 cm foam plastic plate, after perforation used as cutting fixed material; second, to keep the water quality of cutting clean, can be put into a few pieces of charcoal for anti-corrosion. 3. Grafting can be carried out by using one-year-old seedlings of mountain peach and hairy peach as rootstocks, budding and propagating peach, longevity peach, red-leaf peach, plum blossom, trifoliate plum, red-leaf plum, beauty plum, etc.; using cuttings of wild rose, pink rose and "ten sisters" as rootstocks, budding and propagating varieties of rose, cut rose and rose, etc.; using potted purple magnolia and white magnolia seedlings as rootstocks, budding and propagating white orchid, Michelia flower, etc.; using potted two-year-old seedling of wax plum as rootstocks, budding and propagating excellent varieties of wax plum; 2-year-old Chimonanthus praecox seedlings can also be used as rootstocks, and grafting is carried out at a position 3 cm to 4 cm away from the ground by adopting a method of tendril ventral grafting and bagging, and whether the seedlings survive can be judged after 7 to 10 days; T-shaped bud grafting is carried out by taking the seedlings of the seeds of Vitex chinesis, Malus hupehensis or Malus pendula and Malus flower as rootstocks to propagate excellent varieties of Malus; Acer palmatum seedlings are taken as rootstocks to be bagged and grafted to propagate seedlings of red maple, feather maple and the like. 4. bead In July, the feasible varieties of flowers and trees for layering propagation are: Milan (high pressure), Chimonanthus praecox, Honeysuckle, Hydrangea, Campsis, Qionghua, Oleander, Delicious flower, broom, Osmanthus fragrans, Gardenia, Magnolia, Jasmine, Pearl orchid, vine rose, Yingchun, etc. 5. ramets Ornamental plant species that can be divided in July are: Hosta, Purple Calyx, Acorus, Umbrella, One-leaf Orchid, Evergreen, Bromeliad, Twelve Volumes, Chlorophytum, Ophiophora, Auspicious Grass, Onion, Nephropteris, Iris, Bambusa suspensa, etc. II. Harvesting seeds and transplanting 1. Harvesting seeds July can be harvested grass flower seeds are: hollyhock, mallow, morning glory, Xia Cao, petunia, phlox, digitalis, snake chrysanthemum, sweet pea, daisy, delphinium, pansy, pine leaf chrysanthemum and so on. July can be harvested flowers and trees seeds are: Chimonanthus praecox, plum, peach, peach, plum, etc. 2. Transplanting and potting July is the main time period for Chen to put grass flowers in pots during the National Day. At this time, the grass flowers transplanted in pots can be seedlings or cuttings. After three months of careful maintenance, they bloom during the National Day for festival decoration. They are mainly: a string of red, early chrysanthemum, globeflower, small lily, guinea balsam, dragon mouth flower, marigold, peacock grass, skin, atterina, sulfur chrysanthemum, cockscomb and so on. Tree transplantation is generally not carried out in July, but in some special cases, it is feasible to transplant some flowering shrubs with soil balls, such as Mahonia, Hypericum, Ligustrum aurantifolium, Berberia rubra, Peach leaf coral, Dragon cypress ball, etc. However, it is necessary to prune in a targeted manner, set up a shed in time for shade, and increase the number of water sprays. After it basically survives, it will be transferred to normal management. It must not be careless. III. Flower Management 1. Water the flower species that enter half dormant state when high temperature, such as safflower sorrel, geranium, fuchsia, clivia, calla lily, begonia, sedum, longevity flower, cactus, crystal palm, big flower rhinoceros, emerald pearl, big crescent moon, daphne, crab claw orchid, purslane tree, aloe, etc., because the temperature is too high, its growth activity basically stops, metabolic level is very low, should reduce watering, keep basin soil moist, and pay attention to shade and ventilation, Create a relatively cool environment for it. If too much watering, easy to cause plant rot roots, but also seriously affect its recovery after autumn growth. In July, the flower species that enter deep dormancy state at high temperature, such as cyclamen, lycoris, ranunculus, and lotus peony, show that the stems and leaves on the ground wither, the vegetative fibrous roots die underground, and the underground stems or roots sleep in the soil for summer. For flowers in deep dormancy, stop watering, move to a cool place, and keep the pot soil not too dry. For the vigorous growth of flower species, especially foliage plants, such as cycad, one-leaf orchid, turtle, rubber tree, white peony, jasmine, Milan, pearl orchid, araucaria, arrowroot, syncarp, red (green) gemstone, green giant, green king, green queen, powder Dai Ye, Brazil iron, fortune tree, camellia, tea plum, peach leaf coral, torch fruit, Dai Dai, lemon, podocarpus, pomegranate, bauhinia, wisteria, rose, etc., not only to increase the amount of watering and increase the number of watering, Also appropriate to give foliar spray, spray irrigation combination. Especially in the case of continuous cloudy days, due to the high temperature and dry air, it is also necessary to give watering and spraying, and must not be careless. Once the pot soil is found to be too dry and the leaves wither, spray water on the leaves first, and then water the roots after the leaves are restored. Do not irrigate the roots violently, otherwise it is easy to cause woody flowers to "drop green leaves", or cause the decay of plant nutrient fibrous roots, or even cause plant death. For potted plum trees, due to the flower bud differentiation period from July to August, appropriate "water" should be given to promote the normal differentiation of flower buds. The method is: keep the leaves of potted plants slightly curled inward to control the vegetative growth; if the vegetative growth of branches cannot be controlled, only one leaf at the base can be retained after the second shoot shoots are taken out, and flower buds can still be differentiated between the leaf axils. July, to potted flowers watering, should avoid a few hours around noon, before 10 a.m., after 4 p.m. watering is appropriate, so as not to water temperature and soil temperature difference is too large, affecting the growth of potted ornamental plants. In case of continuous rainfall in this month, check the flowerpot in time after rain. When there is accumulated water in the flowerpot, pour it out in time. After the pot soil is slightly dry, loosen the soil again to avoid rotten roots of potted plants. 2. fertilization There are four kinds of ornamental plants that should be strengthened fertilization management in July. First, the flowering period is particularly long, from spring and summer to autumn species, such as Magnolia, rose, Milan, jasmine, etc.; Second, autumn flowering species, such as chrysanthemum, osmanthus, hibiscus, etc.; Third, winter flower appreciation species, such as Dai Dai, Tianzhu, wax plum, azalea, etc.; Fourth, foliage plants, such as palm bamboo, turtle bamboo, spring feather, rubber tree, etc. The type of fertilizer, for the first three types, in addition to the necessary nitrogen fertilizer, but also appropriate amount of phosphorus, potassium fertilizer, in order to meet the overall needs of the plant for nitrogen, phosphorus, potassium, for its budding, flowering and fruit, to provide adequate nutrition guarantee; for the foliage plants, it should be based on thin cake fertilizer solution or urea solution. Fertilization method, with thin liquid fertilizer irrigation is good. July should strengthen fertilization of grass flowers are: a string of red (white, purple, pink), cockscomb, aster, hundred days red, thousand sun red, chrysanthemum, black heart chrysanthemum, petunia, golden bud flower, shrimp clothing flower, orchid, marigold, purple jasmine, Longkou flower and so on. Woody flowers are: Lagerstroemia, pomegranate, poinsettia, Michelia, osmanthus, camellia, tea plum, hibiscus, jasmine, white peony, Milan, evening primrose, rose, begonia, mandarin duck jasmine, triangular plum, azalea, pearl orchid, wax plum, hibiscus, hibiscus and so on. There are many kinds of foliage plants, such as pineapple, Brazil iron, palm bamboo, Araucaria, arrowroot, arrowroot, green giant, ruby, cycad, rubber tree, turtle bamboo, red banana and so on. In July, fertilization must be stopped for ornamental plants in dormant or semi-dormant state, especially for those fleshy ornamental plants, such as sedum, fairy pen, pine leaf chrysanthemum, leopard bark flower, etc., to prevent plant decay. 3. Pruning, picking buds summer feasible topping off the buds of ornamental plants, must be some vigorous growth, germination, pruning resistant species. Topping refers to picking the tender terminal buds directly with your fingers. The bonsai plants suitable for picking are mainly: Ulmus chinensis, Prunus chinensis, Photinia chinensis, Gossypium hirsutum, Buxus chinensis, Chimonanthus praecox, Pyracantha fortunei, Podocarpus podocarpus, Tamarix chinensis, Elaeagnus chinensis, Vitex negundo, Golden bell, Celtis chinensis, Fujian tea, Banyan tree, Fraxinus chinensis, Acer triangularis, Lagerstroemia indica, June snow, Murraya chinensis, etc. Pruning refers to the pruning of a part of the new shoots with scissors, which promotes the germination of the lower lateral buds and makes them form beautiful crowns or trees. Suitable for pruning bonsai plant species, mostly not easy to pick with fingers woody ornamental plants, such as juniper, Platycladus orientalis, Sabina, cypress, oak, cat thorn, true cypress and so on. For those potted flower species that continue to bloom for a long time, such as Milan, Rose, Jasmine, Pearl Orchid, etc., the residual flower and sterile stem should be picked in time, and the flowering branches should be cut down necessary to promote the germination and re-flowering of the lower lateral buds. For rhododendron, camellia, tea plum, begonia, wax plum, plum blossom, etc., the long branches protruding from the crown should also be cut down in order to form a better crown shape. 4. shading July is the month with the strongest sunshine and highest temperature in a year, so special attention should be paid to shade management of potted ornamental plants. Ornamental plants that like shade or semi-shade must be moved under shade to avoid sun exposure and damage to plants. Such as ferns, hairpin, purple calyx, turtle bamboo, camellia, tea plum, azalea, pearl orchid, Stagelina, orchids, palm bamboo, rubber tree, red (green) gemstone, spring feather, powder bud leaf, green radish, pepper grass, one-leaf orchid, hanging bamboo plum, Brazil iron, unicorn leaf, pineapple, arrowroot, auspicious grass and so on. For light-loving species, sufficient light can be given, such as pomegranate, wisteria, Lagerstroemia, Pyracantha, Jasmine, June snow, Cycas, Sabina, Platycladus orientalis, Peach Blossom, Plum Blossom, Chimonanthus praecox, Ulmus, Sparrow Plum, Acer Triangle, Black Pine, Water Myrica rubra, Oak Tree, Brocade Pine, White Pine, Milan, Rose, etc. And to Podocarpus, bamboo cypress, Michelia, tiger thorn, cloud bamboo, Guanyin bamboo, five-needle pine, etc., it is necessary to give appropriate shade. For small, miniature, shallow potted plants, due to the high temperature this month, the air is relatively dry, in addition to the necessary shade, but also must be buried in wet sand, so as to reduce the evaporation of the surface of the pot soil, but also conducive to the protection of plant nutrition fibrous roots. 5. Air-conditioned indoor flowers have air-conditioned indoor, should choose leaves with a higher degree of leather, or leaf surface is thicker cuticle, slightly resistant to dry environment, strong resistance of flower species, such as rubber tree, star anise, ten mahonia, cycad, Araucaria, golden sunflower, catnip, palm bamboo, Canadian jujube, pineapple, spring feather, turtle back bamboo, goosefoot firewood, one-leaf orchid, peach leaf coral, etc., and should not choose kidney fern, colored leaf grass, green giant, etc. In addition, in management, attention should be paid to the combination of watering and spraying, and away from the air outlet of the air conditioner, in order to prevent wind from blowing directly on the plants, causing their leaves to wither and burn. 6. Disease and pest control (1) Orchid buds in July when the leaves, leaf tip part easily infected with anthracnose, gradually spread to the whole plant, serious will lead to plant wilt death. This disease may occur all year round, poor ventilation, high temperature and humidity, continuous rain, more conducive to the propagation and transmission of bacteria. Ventilation should be strengthened and 75% chlorothalonil wettable powder 800 times solution or sterilization Dan 500 times solution should be sprayed during the onset period for prevention and control. (2) When reddish-brown sawdust accumulation occurs on the stump or trunk of plum blossom, peach blossom, begonia, red leaf plum, cherry blossom, trifoliate plum, etc., most of which are caused by the larvae of pink neck longicorn. Artificial killing, injection of internal absorbent pesticide, insertion of poison stick, soil burying carbofuran and other methods can effectively kill the larvae in the trunk. Note that when injecting pesticides, avoid using dimethoate, omethoate, etc., in order to prevent causing phytotoxicity. (3) In July, it is necessary to prevent and control in time the wild borer of Buxus chinensis, Buxus chinensis, Buxus chinensis and Buxus chinensis. When the insect occurs seriously, it can gnaw all the leaves. Once discovered, pesticides such as trichlorfon, dimethoate or fenvalerate can be sprayed in time. If long-term use of a pesticide has made it resistant, a new pesticide type can be changed. (4) In July, some areas will continue to appear citrus butterfly larvae harm Dai Dai, kumquat, kumquat, fingered citron, lemon, fragrant round, rue and other new shoots of the leaves, should be timely sprayed stomach poison pesticides to kill (5) White wax insect, which damages Ligustrum lucidum, Ligustrum microphylla, water wax and Fraxinus chinensis, has its emergence period from late July to late August. It is necessary to spray pesticides such as quick kill at the right time to prevent white wax insect from harming again in the next year. (6) The Japanese turtle wax scale is the main pest that harms Euonymus, Fawu, Pittosporum, Camellia, Red-leaf plum, Cedar, etc. When it is serious, the insect body is often covered with branches and leaves, and its nymph hatching peak is in early July. Pesticides such as dimethoate and quick kill can be sprayed in time for control. IV. Bonsai modeling In July, due to high temperature, low air humidity and vigorous growth of plants, branches are easily infected and bacteria are not easy to heal and recover after damage. Most tree stump species are not suitable for winding and binding modeling. Some plant species with strong adaptability and resistance can be modeled, and it is required to be potted in spring or planted in the ground. They are: Yingchun, Ginkgo biloba, Podocarpus, Arhat cypress, Cuibai, June snow, black pine, Buxus seeds, water bayberry and so on. July plant modeling should be careful, light pan slow tie, slowly with strength, not eager to operate, too hard, otherwise it is easy to lead to plant branches, stems broken, endangering its survival. Solar terms in July: July 7 small heat; July 23 big heat.

For species that continue to bloom, such as rose, cinnamon, cinnamon, pomegranate, hibiscus, crape myrtle, leaf flowers, dahlias, and five-colored plums, as well as those that will bloom, such as sweet-scented osmanthus, chrysanthemum, hibiscus, autumn peony, etc., we should promptly apply an appropriate amount of available phosphorus and potassium fertilizer. For camellia, tea plum, plum blossom and wax plum which are in flower bud differentiation, a small amount of potassium dihydrogen phosphate can be sprayed by foliar topdressing. 5. Prevention and control of diseases and pests. In August, scale insects on cedar, privet, Haitong, sweet-scented osmanthus, crape myrtle, heather, camellia and other plants should be promptly sprayed with 1500-fold solution to control. For chrysanthemum tigers and aphids planted on the ground, 1000 times of trichlorfon crystal can be sprayed to kill them. The larvae such as rose leaf wasp and Spodoptera litura that ate rose leaves were promptly sprayed with 1000 times of fenvalerate to control. 6. Seed collection. In August, the woody flower species that can collect seeds are: peony, elm leaf plum, safflower oil tea, Luohansong, summer wax plum and so on. The grass flowers that can collect seeds are: peony, sunflower, purple jasmine, Fulukao, Lingcao, alpine snow and so on. Management of potted flowers in courtyard 1. Watering. In August, it should be watered between 9 and 10:00 in the morning and after 4 o'clock in the afternoon to keep the water temperature basically consistent with the soil temperature and air temperature. For those ornamental plant species that like acidity, 0.1% ferrous sulfate can be added to the irrigation water. It is worth noting that for ornamental plants with dense hairs on their leaves, such as Baobao, Tripterygium, Tripterygium, Begonia, etc., the leaves are not easy to evaporate after droplets, which can easily lead to leaf rot, and only a small amount of spray is feasible; the flower buds of Fulang flower (African chrysanthemum) and the leaf center of Magnolia can not be drenched with water, and the flow of dirty water into the leaves will cause heart damage. Pineapples must be watered less, sprayed more, and injected water into the leaf tube in order to meet their needs. When watering and spraying potted plants this month, you must pay attention to loosening the soil, but every 10 days, otherwise it will lead to pot soil hardening due to repeated watering. For dormant and semi-dormant flower species, watering and spraying should be controlled to keep the basin soil slightly moist, and a relatively cool environment can be created by spraying water around the flowerpot. 2. Fertilizing. In August, foliage plants Such as tortoise back bamboo, one-leaf orchid, rubber tree, spring feather, brown bamboo, red (green) gemstone, southern sequoia, golden wasabi, beautiful needle sunflower, sunflower, fishtail sunflower, sunflower, green apple, Brazilian wood, Dutch iron, fortune tree, kidney fern, dew tree, ash wood (African jasmine), orchid cinnamon (peace wood), gold coin tree (dragon and Phoenix wood), taro, green emperor, green queen, poinsettia, pink leaf, goose palm wood, peach leaf coral, green queen Pocket coconut, leafy wood, star anise gold plate, etc. Can be applied with low concentration of liquid fertilizer, such as urea, flower special fertilizer or cake fertilizer. For species with long flowering period, such as rose, magnolia, jasmine, pearl orchid, crape myrtle, pomegranate, Milan, four seasons cinnamon, cinnamon, triangular plum, five-colored plum, etc., as well as daidai, bergamot, kumquat, lemon, rich seeds, firethorn, golden marbles, pomegranate, pumpkin, papaya, etc., in addition to ensuring nitrogen supply, we should also apply appropriate amount of available phosphate and potassium fertilizer, such as potassium dihydrogen phosphate and so on. For potted grass flowers blooming in autumn, such as red, thousand-day red, dry chrysanthemum, marigold, peacock grass, longkou flower, chrysanthemum, chrysanthemum, pocket sunflower, etc., thin liquid fertilizer can be applied every semimonthly to ensure the reproduction of leaves and flowers after autumn. For the species of flowers and trees in flower bud differentiation, such as camellia, tea plum, plum blossom, sweet-scented osmanthus, rhododendron and so on, low concentration of phosphorus and potassium fertilizer should be applied to the leaves. When applying organic fertilizer to ornamental plants, do not drop the fertilizer on the leaves, so as not to cause the leaves to rot. For the sake of safety, spray water on the leaf surface in time after fertilization to rinse away the fertilizer droplets that may adhere to the leaves. For ornamental plant species in dormant or semi-dormant state, such as orchid, crabapple, calla lily, cyclamen, Daphne, aloe, longevity flower, purslane, crab claw orchid, sedum, purple triangle leaf sorrel, cactus, cactus, etc., it is necessary to stop all forms of topdressing, otherwise it is easy to lead to rotten roots or death. 3. Shade. In August, the heat is still strong, so it is still very important to manage the shade of potted flowers in the courtyard. For those cool ornamental plant species Such as tortoise back bamboo, spring feather, cherry angel, rubber tree, hulk, hulk, taro, taro, red (green) gemstone, brown bamboo, green apple, green emperor, green queen, bluegrass, pink daiye, pepper grass, pineapple, water mass flower, mirror grass, fern, Buddha belly bamboo, Phoenix tail bamboo, hanging orchid, auspicious grass, pocket coconut, netted grass, purple velvet, blood leaf orchid, silver silk grass, black leaf Guanyin lotus, crystal candle, anthurium, anthurium Begonia, rich bamboo, one-leaf orchid, asparagus, purple calyx, etc. Can continue to give shade, pull up the shade net at 9: 00 in the morning, and then withdraw after 4: 00 in the afternoon. If the number of potted flowers is small, they can also be moved indoors for 6 to 7 hours before and after noon. If there are conditions, you can also move it to the shade of big trees and wait until the middle of September to move out from the shade of trees. 4. Trim. In August, those stump bonsai that are vigorous, pruning-resistant and easy to germinate continue to be heart-picked or trimmed, such as hammer elm, Finch plum, Fujian tea, banyan tree, white wax, bayberry, melon seed and yellow poplar. Cut the rose, pomegranate, Milan and so on after each flower. For potted chrysanthemums, it is necessary to do a good job of sprouting and bud removal? BR > 5. Control diseases and insect pests. In August, scale insects, citrus butterflies, rose leaf wasps, peach red-necked longicorn beetles and other pests should be controlled. Pay attention to the prevention of orchid leaf diseases, including anthracnose, Botrytis cinerea, leaf blight and so on. Pay attention to the control of chrysanthemum aphids, leaf moths, borer and so on. Potted plants suitable for balcony display in August, the balcony is still hot and dry, and only some potted ornamental plants with strong resistance or long-term shelving on the balcony can adapt. Such as black pine, brocade pine, five-needle pine, hammer elm, Finch plum, water bayberry, wolfberry, holly, wax plum, fruit pomegranate, pomegranate, melon seed yellow poplar, Platycladus orientalis pile, round cypress, ground cypress, oak, white wax, Fujian tea, rose, leaf flower, tequila, five-colored plum, ginkgo, jasmine, Milan, triangular maple, Luohan pine and so on. In August, some of the flowers and trees on the balcony can be transferred to air-conditioned rooms. Such as Cymbidium, Dendrobium, Cartland, Orchid, Orchid, Oncidium, South American iron tree, black leaf Guanyin lotus, crystal candle, red palm, hulk, red (green) gemstone, taro, sunflower, king coconut, cherry, tortoise back bamboo, orchid, green apple, palm bamboo, rich tree, gentleman orchid, inverted golden bell, reticulate grass, golden bract, Brazilian wood, star anise plate and so on. The propagation of flowers on the balcony in August, large diameter flowerpots can be used on the balcony, covered with plastic film, moisturizing and cutting some ornamental plants, and the cutting substrate can be mixed with rice bran ash and fine sand in the ratio of 2 ∶ 1, or vermiculite can be used alone. The ornamental plants that can be cut are: goose palm wood, golden peach leaf coral, bamboo begonia, gardenia, golden bracts, coral flowers, cinnamon, pearl orchid, plantain, jasmine, Guangdong evergreen, silver silk grass, camellia, camellia, Camellia, Michelia, etc., which should be moved indoors 5 to 6 hours before and after noon. Some ornamental plants can also be inserted indoors, but the water must be changed frequently, such as rose, gardenia, jasmine, pearl orchid, goose palm wood, peach leaf coral, figs, plantains, Burmese gardenia, geraniums, Guangdong evergreen, hanging golden bell and so on. Balcony flower management 1. Watering. The watering and spraying of potted flowers on the balcony in August should be careful. First, the difference between water temperature and soil temperature and air temperature is too big; second, we should pay attention to the time of watering and spraying, which can be carried out before 10:00 or after 4 p.m.; third, while watering, loosening the soil for potted plants should not be ignored. fourth, it is best to put a small amount of ferrous sulfate in irrigation water to meet the needs of most ornamental plants in acidic soil environment. If the balcony is more spacious, you can use bricks to build a simple sand pool with 10 cm thick wet sand, and then put some more humid potted flowers on the wet sand, such as: tortoise back bamboo, one-leaf orchid, cherry, camellia, tea plum, taro, spring orchid, Jianlan, pineapple, red (green) gemstone, magnolia, etc., usually spray water instead of watering, it is very beneficial to its safety over the summer. For Cymbidium, Cymbidium, Oncidium, Cartland, inverted Golden Bell, Dendrobium, Crystal Candle, Black Leaf Guanyinlian and so on, they can be moved to an air-conditioned room and watered instead of watered to ensure that they can spend the summer normally. For flowers that are more heat-resistant on the balcony, such as rose, Milan, jasmine, pomegranate, triangular plum, hammer elm, Finch plum, melon seed yellow poplar, triangular maple, black pine, Jinsong, wisteria, Fujian tea, bayberry, tequila, cycad, etc., can be watered once or twice a day and sprayed once or twice a day. 2. Fertilizing. In August, fertilizer should be stopped for potted plants on the balcony that are dormant and semi-dormant. For exuberant foliage plants, 0.3% urea can be sprayed or poured, or multi-component compound fertilizer particles can be applied on the basin. Flowers and trees that mainly watch flowers and fruits, such as Magnolia, Milan, pomegranate, crape myrtle, jasmine, daidai, firethorn, bergamot, kumquat, etc., should continue to apply quick-acting phosphorus and potassium fertilizer. For hammer elm, sparrow plum, wolfberry bone, holly, Luo Hansong, Fujian tea, triangle maple, bayberry, melon seed, etc., after each pruning, you can apply a thin fertilizer. 3. Shade. In August, potted plants shelved on the balcony to receive full light, especially shallow pot piles, such as five-needle pine, Luohan pine, cypress, Fujian tea, plum blossom, triangular maple, etc., can be covered with soft grass, moss or wet cloth on the potted surface, which can not only keep moisture and cool down, but also protect the nutrient fibrous roots distributed in the topsoil from harm. If the balcony is more spacious, sunshade nets can be used to block the light. If there are not many potted flowers and trees on the balcony and are relatively precious, it is best to move them indoors for 5 to 6 hours before and after noon. 4. Trim. In August, most of the stump bonsai shelved on the balcony, such as hammer elm, Finch, June snow, white wax, oak, small bayberry, triangular maple, banyan, Fujian tea, Platycladus orientalis, lobular privet, melon seed yellow poplar, firethorn and so on, still need to be picked or trimmed this month. The stump flowers, withered branches and yellow leaves on other potted ornamental plants should also be cut off in time. 5. Prevention and control of diseases and pests. In August, red spiders are the most vulnerable to red spiders on the balcony. 1500 times of 25% Baileba wettable powder should be sprayed and killed in time. A small number of scale insects on flowers and trees can be removed by pasting transparent glue. The aphids that often appear on chrysanthemums should be sprayed with 1000 times of trichlorfon crystals.

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

The ones that can be planted on the ground are: a string of red, thousand-day red, sulfur chrysanthemum, ground skin, marigold, peacock grass and so on. It is appropriate to pick the heart every 10 days to promote it to form a plump plant shape, and give birth to more inflorescences on the lateral shoots, and stop picking the heart after late September. For woody flowers that bloom continuously for a long time, such as variety rose, abundant rose, miniature rose, rattan rose, crape myrtle, pomegranate, five-color plum, triangular flower, etc., the stump should be cut off in time, and the branches that have flowered should be appropriately shrunk to effectively promote them to blossom again. 3. Watering. In September, the climate is relatively dry, and continuing to do a good job in watering and spraying the trees and shrubs transplanted in the spring in the courtyard is one of the key measures to consolidate their survival effect. The first is to water the roots to keep the soil moist, but not to accumulate water; the second is to spray water on the grass rope wrapped around the trunk to create a locally moist protective layer for the trunk; and the third is to spray water on the crown to reduce foliar transpiration and increase the humidity of the local space. In addition, for the newly planted grass flowers, it is also necessary to do a good job of spraying water and moisturizing. 4. Fertilizing. Colorful foliage plants planted on the ground, such as golden leaf privet, red leaf Berberis, red maple, safflower? Wood, alpinia officinalis, alpinia mandshurica, golden peach leaf coral, red mulberry, red leaf dwarf cherry, red leaf plum, red leaf peach, etc., in order to keep its bright leaf color, phosphorus and potassium fertilizer should be applied properly. For land-planted flowers and trees that blossom continuously or watch flowers and fruits in autumn, such as crape myrtle, rose, cinnamon, tangerine, pomegranate, leaf flower, hibiscus, chrysanthemum, canna, dahlia, plum, southern bamboo, firethorn, cinnabar root, kumquat, etc., as well as a large number of autumn grass flowers, it is appropriate to apply balanced available fertilizer of nitrogen, phosphorus and potassium. For the flowering kumquat, cinnamon, cinnamon and so on, fertilization can be stopped during the flowering period. 5. Pest control. The green thorn moth that harms flowers and trees such as crape myrtle, pyracantha and begonia can be sprayed with 1000 times liquid of trichlorfon crystal for control; for longicorn beetles that harm crape myrtle, papaya and begonia, poison labels can be inserted from the wormhole to control powdery mildew on rose and chrysanthemum plants. 50% carbendazim wettable powder 1000 times solution can be used at the initial stage of the disease. 6. Seed collection. The woody ornamental plants that can be collected are mainly flowers and trees of Magnoliaceae. Such as Tiannu, Michelia, Magnolia, Magnolia, Yunshan Magnolia, Lechang Michelia, Michelia mollissima, Michelia mollissima, Magnolia magnolia and so on. In addition, there are seven-leaf trees, crape myrtle, cloves, begonia, bauhinia, rhododendron, yew, bright-leaf wax plum and so on. The seeds of Magnoliaceae, yew, seven-leaf tree, begonia, etc., must be stored in wet sand until early spring next year, and then sow in the field after the seed crack. The seeds of grass flowers that can be harvested are: marigold, zinnia, impatiens, purple jasmine, cockscomb, Catharanthus roseus, wheat straw chrysanthemum, emerald chrysanthemum and so on. Management of potted flowers in courtyard 1. Watering. In September, the light is strong, the temperature is high, and the air is quite dry, so the watering management of potted flowers can not be ignored. Watering times, for the general wet foliage plants, the first half of the month can be watered or sprayed once in the morning and afternoon, and watered once in the second half of the month, and give foliar spray water appropriately. For most potted flowers and bonsai, it can be watered once a day, supplemented by foliar spraying. Watering time is before 10:00 in the morning and after 3pm. For ornamental plant species that like acid environment, a small amount of 0.1% light green ferrous sulfate powder can be added to the irrigation water. For summer dormant or semi-dormant flower species that resume growth after autumn, the number and frequency of watering (or spraying) can be gradually increased. When watering potted plants, they should loosen the soil every half a month. 2. Fertilizing. September is the period of exuberant growth of most flowers, some dormant and semi-dormant flower species in summer, with the gradual cooler temperature, also began to restore growth, this month should attach great importance to fertilization management. For foliage plants, such as tortoise back bamboo, rubber tree, wealth tree, Brazilian wood, spring feather, brown bamboo, ash ash, cinnamon, money tree (dragon and Phoenix wood), Nanyang fir, fish tail sunflower, green apple, red (green) gem, green emperor, silver queen, bamboo taro, synthetic taro, fir, etc., it is still dominated by low concentration of light fertilizer, such as 0.3% urea, etc. For flowers and trees with special flowering or full flowering in autumn, such as rose, tricolor plum, five-colored plum, pomegranate, crape myrtle, Milan, blue blue, jasmine, four seasons cinnamon, cinnamon, sweet-scented osmanthus, etc., ornamental plants such as daidai, Phyllostachys pubescens, cinnabar root, firethorn, papaya, golden marbles, purple beads, fruit pomegranate, etc., colorful leaf plants such as variable leaf wood, gold-sprinkled peach leaf coral, pineapple, flower leaf banyan, Phnom Penh Brazil wood, Zhu banana, colored leaf grass, etc. Fertilizer types with balanced application of nitrogen, phosphorus and potassium should be applied. For the resuming growing crabapple, geranium, calla lily, cyclamen, four seasons begonia, Daphne, crab claw orchid, sedum, purslane (jade leaf), purple triangle leaf sorrel, gentleman orchid, arrow lotus, etc., low concentration liquid fertilizer can be restored. For flowers that have completed flower bud differentiation and entered the stage of flower bud expansion, such as Camellia, Camellia, Chimonanthus, Plum, Michelia, rhododendron, etc., low concentration nutritionally balanced fertilizers can be applied to potted grass flowers, such as red, marigold, chrysanthemum, chrysanthemum, dahlia, pocket sunflower, etc., thin fertilizer can be applied every 10 days to meet the needs of their pregnant buds and next month's flowering. 3. Shade. In September, the temperature is high and the sun is still strong, so the shading management of potted flowers in the courtyard can not be relaxed. For those species of foliage plants that like shade Such as tortoise back bamboo, rubber tree, kidney fern, Boston fern, bird's nest fern, synthetic taro, taro, green apple, brown bamboo, green emperor, silver queen, orchid, pink daiye, golden horseradish, orchid, autumn begonia, unicorn leaf, cherry, red (green) gemstone, crystal candle, black leaf Guanyin lotus, reticulate grass, red vein jade bed, asparagus, goose palm wood, flower leaf Phoenix tail fern, watermelon pepper grass, flower and leaf evergreen, green giant, red palm, red palm Antler fern, mirror grass, water mass flower, emperor sunflower, rich bamboo, etc. Give 5 to 6 hours of light a day through shade Full light can be given to the species that like light, such as triangular maple, hammer elm, Fujian tea, ginkgo, bayberry, black pine, Platycladus orientalis (pile), round cypress, crape myrtle, southern fir, wisteria, Milan, jasmine, fire thorn, rose, oak, white wax, etc. Wood, epiphyllum, Phyllostachys pubescens, Yushu, rhododendron, camellia, tea plum, bergamot, daidai, kumquat, etc., can be given appropriate shade around noon. The newly transplanted autumn grass flowers should also be shaded properly to prevent the plant from wilting and affecting its growth. 4. Trim. For potted chrysanthemums, we should continue to peel off buds and remove buds, and prune rose, pomegranate, Milan, jasmine, pearl orchid, triangular plum, five-colored plum, golden bract, coral flower and so on after each flowering. For those tree stump bonsai species that are resistant to pruning, easy to germinate and thrive, such as hammer elm, sparrow plum, triangular maple, Fujian tea, banyan tree, red nan, lobular privet, bayberry, melon seed yellow poplar, Platycladus orientalis (pile), true cypress, white wax, Tamarix, etc., continue to prune or pick buds. In addition, the seedlings of the rich trees can be braided and put on the pot. 5. Pest control. The red-necked longicorn beetles on potted plum blossom, begonia, Birthday Bun with Bean Paste Filling, green peach and other plants can be injected with poison and can also be controlled by burying carbofuran granules. The Japanese tortoise wax scale, cotton blowing scale, shield scale, velvet scale and so on appeared on potted flowers and trees were controlled with 1500 times liquid of 40% speed culling. Potted plants suitable for balcony display in September, the balcony is still strong light, dry air, only some long-term put on the balcony potted flowers or potted plants with strong resistance, can adapt to the special environment on the balcony. They are: black pine, golden pine, red pine, five-needle pine, hammer elm, Finch plum, bayberry, triangular maple, wolfberry, holly, wax plum, pomegranate, melon seed yellow poplar, Platycladus orientalis (pile), round cypress, Fujian tea, white wax, banyan, leaf flower, rose, tequila, ginkgo, Milan, jasmine, park tree, Luo Han pine, thorn, five-colored plum and so on. For some flower species that prefer a cool environment, they can continue to be placed in air-conditioned rooms, such as Cymbidium, Oncidium, Dendrobium, Cartland, Wandai Orchid, Spider Orchid, Black Leaf Guanyin Lotus, Crystal Candle, Anthurium, Gentleman, inverted Golden Bell, Reticulate Grass, etc. For some common foliage plants, they can be moved indoors in 4 to 5 hours before and after noon, such as brown bamboo, tortoise back bamboo, Brazilian wood, rich tree, green apple, one-leaf orchid, loose-tailed sunflower, fish tail sunflower, king coconut, spotted oak tree, sprinkled peach leaf coral, goose palm wood and so on. The breeding of flowers on the balcony in September, you can continue to use large-caliber flowerpots as containers on the balcony, with a mixture of bran ash and wet sand accounting for 1 and 2 respectively, moisturizing with plastic film, and can be cut and propagated some ornamental plants, such as gardenia, plantain, sprinkled peach leaf coral, goose palm wood, Japanese cinnamon, four seasons cinnamon, camellia, tea plum, pearl orchid, jasmine, red back cinnamon, coral, golden bract, smile, silver bright silk grass and so on. You can also insert goose palm wood, rose, gardenia, figs, Guangdong evergreen and so on in indoor water. Balcony flower management 1. Watering. For some ornamental plants that like wetting, such as Chunlan, Jianlan, Magnolia, tortoise back bamboo, one-leaf orchid, camellia, tea plum, cherry, pearl orchid, pineapple and so on, they can be put on the plank on the balcony pool or tank, or in the simple sand pool built by themselves, and usually spray water instead of watering. For potted foliage plants shelved indoors, they should also spray more water and less watering, so as to keep the pot soil loose and moist; especially in the air-conditioning room, spray water at least once or twice a day, otherwise even the five-needle pine bonsai, which is more drought-resistant, will lose water and die without watering or spraying for 5 to 7 days. Potted ornamental plants with strong resistance on the balcony can continue to be watered once a day and sprayed once or twice a day, or soaking pot method can be used to prevent the occurrence of wet and dry soil. Watering time should still avoid 2 to 3 hours before and after noon, pay attention to the difference between water temperature, soil temperature and air temperature, and add a small amount of light green ferrous sulfate to the irrigation water to avoid physiological yellowing. 2. Fertilizing. Low concentration liquid fertilizer should also be applied to potted flowers that gradually recover from dormancy or semi-dormancy; for potted pile heads with vigorous growth, dilute liquid fertilizer can be applied once after heart-picking and pruning; for potted flowers and trees that mainly view flowers and fruits, such as Magnolia, rose, pomegranate, crape myrtle, jasmine, pearl orchid, daidai, hot thorn, bergamot, kumquat, etc., we should continue to apply quick-acting phosphate and potassium fertilizer. For potted flowers that have completed flower bud differentiation and whose buds are growing, such as Camellia, Camellia, Chrysanthemum, Plum, Osmanthus, Chrysanthemum, etc., according to different species, appropriate amount of available phosphorus and potassium fertilizer or nitrogen, phosphorus and potassium balanced multi-component compound fertilizer can be applied. On the balcony to the kinds of flowers and trees topdressing, do not have a peculiar smell, especially can not have a bad smell, pouring attention to do not splash downstairs, careful operation. 3. Shade. For the stump bonsai and potted flowers shelved on the balcony to receive full light, in order to reduce watering, prevent soil hardening, and protect the nutritious fibrous roots distributed in the surface of the potted soil, you can continue to cover the potted surface with wet grass, moss, wet cloth, etc.; when the number of potted flowers is small, it can be moved indoors in 5 to 6 hours before and after noon; if there are more potted flowers and the conditions are available, you can continue to stand and pull up the sunshade to block the light. 4. Trim. In September, bonsai stumps placed on the balcony, such as hammer elm, sparrow plum, bayberry, melon seed yellow poplar, triangular maple, banyan tree, Fujian tea, Platycladus orientalis (pile), round cypress, cedar, lobular privet, white wax, etc., still need to be coring or pruning. The withered branches, yellow leaves and abortive stems of other potted flowers and trees should also be cut off in time. 5. Pest control. In September, when the temperature on the balcony is high and the air is dry, potted flowers and trees are most vulnerable to the harm of red spiders, which can be sprayed with 1500 times of 25% Begonia wettable powder. Longicorn beetles on dragon cypress, cypress and juniper bonsai, and pink-necked longicorn beetles on plum blossoms, begonia, papaya, Birthday Bun with Bean Paste Filling and other flowers and trees can continue to be injected with poison labels or buried with carbofuran for control. A variety of scale insects harmful to camellia, pyracantha, crape myrtle, wax plum and other flowers and trees can be artificially erased when the number is small, and can be sprayed with 1500 times of quick culling liquid to control when the number is large.

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.

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)

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Flower planting Handbook (December)

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

I. Flower reproduction

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

two。 Cuttings. The woody ornamental flowers and trees that can be cut in the open field in December are plum blossom (mainly palace powder, green calyx, etc.), rose (mainly Elizabeth, abundant rose, miniature rose, etc.). Red leaf plum, wax plum (with heel cutting), Spiraea, yellow poplar and so on. Among them, yellow soil should be used for cutting plum blossom and red leaf plum, mixed substrate of rice chaff ash and fine sand 2 ∶ 1 should be used for rose cutting, and general sandy soil should be used for other kinds of cutting, which can be covered with plastic film to keep heat and moisture.

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

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

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

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

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

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

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

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

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

The stumps and flowers that can be put on the pot in December are: plum blossom, wax plum pile, camellia, tea plum, pedicel begonia, vertical silk begonia. It is expected to blossom during the Spring Festival by putting it in the greenhouse and promoting the flowering treatment.

In December, potted hyacinths, tulips and daffodils continue to be put in the shed to promote flowering, which can promote their flowering before and after the Spring Festival.

1. Keep out the cold. In a simple plastic greenhouse with a temperature of no less than 0 ℃, the following ornamental plants can be placed without freezing damage, such as Penglai pine, Tianmeng, one-leaf orchid, star anise plate, coral of golden peach leaves, sunflower, kidney fern, palm bamboo, Phyllostachys pubescens, Michelia, rich seeds, fire thorns, camellias, spring orchids, cymbidium, Phoenix tail bamboo, Phyllostachys pubescens, cycads, etc.

Ornamental plant species with an overwintering temperature of not less than 5 ℃, such as southern fir, goose palm wood, rubber tree, jasmine, brandy, pearl orchid, pocket coconut, calla lily, spring feather, tortoise back bamboo, Jianlan, Mulan, Belgian rhododendron, triangular flower, cyclamen, primrose, five-colored plum, kumquat, daidai, lemon, loose-tailed anemone, geranium, mulberry, Buddha belly bamboo, etc., can overwinter in a double-layer plastic greenhouse. For the species requiring a winter temperature of not less than 10 ℃, such as variable leaf wood, taro, pepper grass, bamboo taro, rich bamboo, fishtail sunflower, Brazilian iron, rich tree, reticulate grass, pineapple, pink leaf, poinsettia, Cymbidium, Longtuzhu, golden bract, Milan, Phalaenopsis, Cartland, Magnolia, South American iron tree, red (green) gemstone, Oncidium, tiger orchid, etc., in a double-layer greenhouse with good sealing performance. It is also necessary to heat it up properly. in the particularly cold period, from 4: 00 p.m. to 9: 00 the next day, put a grass curtain on the roof of the greenhouse, and then remove it until the temperature gets warmer.

For those more hardy potted and bonsai plant species, such as wax plum, plum blossom, begonia, Yingshanhong, pomegranate, hammer elm, sparrow plum, oak, crape myrtle, wisteria, yellow poplar, Luohansong, triangular maple, Cuibai, garden cypress, red cypress, bayberry, Chinese wolfberry, white wax, etc., generally will not be frozen when not less than-10 ℃; in particularly cold weather, cover with plastic film or soft grass to prevent cold.

[page] whether the bonsai, potted flowers, foliage and fruit plants are placed in the greenhouse, greenhouse or in the living room, in addition to maintaining the appropriate indoor temperature, we should also pay attention to ventilation. The doors and windows can be opened around noon with the highest temperature of the day to prevent the occurrence of fallen leaves, flowers and fruits. In the ventilation, we must also pay attention not to let the cold air directly attack the plant, so as to avoid adverse reactions.

two。 Water it. For most of the potted flowers and bonsai placed in the greenhouse, greenhouse and bedroom, the degree is to keep the basin soil moist. If the temperature is too low and watered too much, it is easy to cause rotting roots. When the temperature rises, the amount of water can be increased and proper foliar spray can be given.

For those potted flowers that blossom before and after the Spring Festival, such as camellia, tea plum, Belgian rhododendron, plum blossom, wax plum, melon chrysanthemum, primrose, longevity flower, hyacinth, European daffodil, etc., ornamental fruits such as daidai, lemon, bergamot, tangerine, golden bean, winter coral, rich seeds, Phyllostachys pubescens, etc., should not only keep the potted soil moist, but also spray the leaves to facilitate the expansion of flower buds. It can also increase the freshness of flowers and fruits.

For most foliage plants in the shelving room, we should not only keep the basin soil moist, but also spray water on the foliage surface, and always keep the foliage surface clean; for those foliage plant species that are not very cold-resistant, such as Fendai leaf, fruit taro, bamboo taro, leaf-changing wood, silver queen, etc., when the room temperature is close to the minimum temperature they can bear, special attention should be paid to controlling the amount of water to ensure that they can survive the winter safely.

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

Newly transplanted flowers and trees outdoors should be checked frequently and replenished in time; for transplanted evergreen trees, foliar spray can be given around noon to prevent leaves from drying and falling off.

3. Fertilize. For most of the potted flowers and trees, foliage plants and bonsai placed in the general greenhouse, fertilizer should be stopped, otherwise it is easy to cause the plant to rot and die.

Most of the green trees and flowers planted on the ground Such as Begonia, Magnolia, Magnolia, Magnol Cryptomeria fortunei, cedar, cypress, Robinia pseudoacacia, elm leaf plum, Yu Li, white silk plum, heather, bauhinia, hibiscus, etc. While ploughing the garden field in December, fertilizers such as cake fertilizer, pig and cow manure, pond mud and septic tank residue can be applied to the periphery of the plant root system, so as to lay a good material foundation for next year's growth and flowering.

For potted flower species placed in the room from 10 ℃ to 15 ℃, such as camellia, tea plum, rhododendron, plum blossom, wax plum, golden bract, shrimp flower, pineapple, Ruixiang, melon leaf chrysanthemum, primrose, cyclamen, pedicel begonia, hyacinth, gentleman orchid, tulip, freesia, etc., 1.2% potassium dihydrogen phosphate can be applied to promote the pregnant bud and flowering of the plant.

4. Trim. The hedgerows, green walls and ball shapes that have not been pruned in November are trimmed, such as privet, lobular privet, Fa Qing, big leaf boxwood, Shu juniper, four seasons cinnamon, spinulosa heather, etc.; balls such as gooseberry, bayberry, heather, yellow poplar, Haitong, Admiralty, pyracantha, dragon cypress, juniper, etc., can be fertilized while completing pruning.

The ground-planted flowers and trees that have not been pruned in November, such as rose, crape myrtle, palm, red leaf plum, heather, Fatong, plum blossom, wax plum and so on, can be pruned and fertilized around the root system after pruning.

For bonsai plant species dominated by shearing, such as hammer elm, sparrow plum, medlar bone, Fujian tea, maple, oak, white wax, fire thorn, June snow, Luohansong, cypress, cypress, begonia, papaya, etc., continue to prune in December to lay a good skeleton for next year's growth; plants that have not changed pots for many years can be combined with pruning to change pots.

5. Pest control. For flowers and trees that are prone to diseases and insect pests in the leaves of grape, begonia, rose, rose, camellia, crape myrtle, etc., the litter under their plants will be collected and burned, which can reduce the occurrence of diseases next year. At the same time, spray stone sulfur mixture for sterilization and disinfection.

For powdery mildew of potted melon-leaf chrysanthemum and Botrytis cinerea of primroses, the former was controlled by triadimefon or thiophanate-methyl in time, and the latter was controlled by thiophanate-methyl.

For the species of scale insects that are easy to appear in flowers and trees in the greenhouse, such as hadai, bergamot, cycad, camellia, orchid, etc., you can first wipe them with a dishcloth, and then use pesticides such as quick culling.

When there is poor ventilation, aphids often appear on potted plants, such as Magnolia, Milan, daidai, rose, Fujian tea, etc., can be controlled by tobacco water.

On the trunk and big branches of flowers and trees such as Haitong, sweet-scented osmanthus, Fatong, camellia, lobular privet, pyracantha, oleander, begonia, Magnolia, bauhinia, gardenia, cedar, heather, crape myrtle, wax plum, etc., there are many kinds of scale insects that often appear on the trunk and big branches of flowers and trees, such as horned wax scale, Japanese tortoise wax scale, red wax scale, shield scale, sagittal scale, pink scale, velvet scale, etc., at this time, spray and kill with high concentration of pesticides such as quinathulfan, quinathulene, buprofezin and other pesticides. Drug damage is rarely caused.

6. Compost. In order to meet the needs of raising seedlings and preparing culture soil next year, rapeseed cake, bean cake and tea seed cake can be poured into water tank and pool for sealed soaking fermentation.

Dry withered grass, fallen leaves, shrubs, branches, etc., are piled up in layers with the garden soil, ignited and burned to form burning soil, which is a good covering soil for sowing and raising seedlings next year.

Compost, pond mud, chicken droppings and pigeon manure were mixed with garden soil and sealed fermentation, which can be used for topdressing seedlings and preparing culture soil in the coming year.

7. Prepare culture soil. Make use of your winter free time to find an open space or pile up as much culture soil as possible in the shade of trees in case you need to change pots and plant flowers next spring. Generally, there are 4 parts of garden soil, 2 parts of rotten leaf soil (or 2 parts of alpine humus soil), 1 part of fine sand, 1 part of piled sawdust, tobacco dust or bran ash, plus about 5% retted cake fertilizer and 2% to 3% compound fertilizer. Among them, garden soil and rotten leaf soil should be screened, gravel, tree roots and other sundries should be sifted, fully mixed, covered with plastic film, and can also be stacked indoors after 3 to 4 months. It can be used for changing pots or potting grass flowers.

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

The ornamental plants suitable for bonsai modeling in December are: Luohan pine, Luohanbai, garden cypress, cypress, velvet cypress, Platycladus orientalis, Sabina vulgaris, black pine, five-needle pine, red pine, bayberry, wolfbone, holly, weeping spear, ginkgo, June snow, broom elm, finch, triangular maple, wax petal flower, Tamarix, pedicel begonia, weeping silk begonia, papaya begonia, melon seed yellow poplar, pearl yellow poplar, wisteria, purple myrtle, banyan, banyan, Fujian tea, white wax, oak and so on.

For bonsai plants fixed with brown wire (rope) or wire, if it has been fixed for one year, or obvious constriction marks are found on the stem or branch, the original ligature should be removed and the wire or brown rope should be used for hanging traction.

For plum piles, Luohansong, begonia, ginkgo, cypress, crape myrtle, etc., after some necessary pruning and plastic surgery, choose a good pot for planting and strengthen management, so that they can be used in public places or rooms for display in the coming year.

In winter, we must carefully manage some shallow landscape bonsai and tree stump bonsai: first, to prevent the roots of plants from frostbite in the basin soil; second, to prevent the disintegration of artificial cemented rocks caused by freezing; and third, to prevent plants planted on rockery from freezing or drying to death. It can be placed in an ice-free place and watered regularly so that it can survive the winter safely.

Flower planting Handbook (January)

The weather characteristics of January: this month is the lowest and coldest month of the year. On January 5, Lesser Cold, just before and after the "39 th Day", most parts of China entered a period of severe cold. On January 20, Greater Cold, the cold air in the north frequently went south, the frost was heavy and the snow was thick, resulting in the lowest temperature of the year. This month's flower conservation, the most important thing is to do a good job in greenhouse, greenhouse and indoor cold-fearing flowers, bonsai, etc., followed by tree pruning, litter cleaning and land preparation, and other auxiliary work.

6. Gather seeds. In January, if there are mature asparagus and magnolia seeds in the greenhouse, they can be picked and sown, mature winter coral seeds, and can also be sown indoors at this time. The seeds of Phyllostachys pubescens, Firethorn, holly and rich seeds can be picked in January, and the seeds can be sown after the seeds are exposed to white.

In January, the seeds stored in sand should be checked frequently, including magnolia, Michelia, heather, holly, etc., to see if there is mildew in the seeds. If mildew occurs, the seeds must be poured out and re-scrubbed, and clean fine sand must be replaced for storage; if the seeds are found to be dry, spray water should be given in time. If it is found that the seed has been white or the radicle has stretched out, it must be sowed immediately and covered with plastic film or rice straw, pine needles and other heat preservation and moisturizing.

two。 Transplanting and planting

In January, grass flowers that can be transplanted and planted in less cold areas are: carnation, kale, calendula, daisies, etc.; in relatively cold areas, after sowing seedlings such as carnation, kale, goldfish grass, pansy and primroses, they can be placed in a simple plastic greenhouse and used as a display of street flower beds, green spaces and flower borders when the air is warmed up in spring.

In January, most deciduous shrubs and green trees can be transplanted and planted Such as hibiscus, pomegranate, bauhinia, begonia, ginkgo, maple, maple, wax plum, plum blossom, white magnolia, red leaf plum, cherry blossom, papaya, two Qiao magnolia, crape myrtle, wisteria, Lingxiao, Linden, Liriodendron, green peach, Chinese tallow, red Spiraea, three branches, rose, Robinia pseudoacacia, dragon claw locust and so on. Evergreen tree species, especially Cinnamomum camphora and Fa Qing, should be transplanted in advance to December or postponed to February this month except for special circumstances. Of course, in places of shelter, intensity shearing is carried out after transplanting, and cold protection and watering management are strengthened after transplanting.

In January, despite the cold weather, the collection of wild tree stumps in the south of the Yangtze River did not affect the collection of wild tree stumps in the process of afforestation and land preparation, mainly deciduous tree stumps, such as Ulmus pumila, Sparrow Plum, triangular Maple, Yingshanhong, crape myrtle, Acer sinensis, wisteria, Wintersweet, Wild Plum, Elaeagnus angustifolia, Weisheng Spear, etc. For evergreen stumps, such as Phyllostachys pubescens, Maoer thorn, medlar, holly, oak, etc., strength shearing must be done and most of the leaves must be deleted. Both deciduous stumps and evergreen stumps should be cultivated by shallow burying and high cultivation, and covered with grass curtain to prevent freezing.

three。 Guard against cold

This month's cold prevention and heat preservation work is the top priority in the management work, a little negligence will bring serious losses to bonsai and bonsai overwintering. According to the lower limit of the lowest temperature that can be tolerated by different flower species, a special environment for them to survive the winter should be created, either in a greenhouse, in a greenhouse, at home, or buried in open soil. In a simple plastic greenhouse of no less than 0 ℃, ornamental plant species that can withstand a low temperature of about 0 ℃ can be placed, such as Penglai pine, Tianmeng, one-leaf orchid, star anise, sunflower, kidney fern, brown bamboo, southern bamboo, peach leaf coral, Michelia, Chunlan, magnolia, rich seeds, Daphne, cycad, calamus, Phoenix tail bamboo, phenanthrene bamboo, white bamboo and so on. In a double-layer plastic greenhouse of not less than 5 ℃, you can put ornamental plant species that can withstand a low temperature of about 5 ℃, such as southern fir, rubber tree, jasmine, pearl orchid, magnolia, pocket coconut, bottle orchid, calla lily, spring feather, tortoise back bamboo, kumquat, daidai, lemon, sunflower, camellia, tea plum, Jianlan, orchid, epiphyllum, Ling Arrow lotus, big Buddha belly bamboo, Belgian rhododendron, triangular plum, five-colored plum and so on. Flower species that can withstand low temperatures of about 10 ℃ can be placed in double-layer plastic greenhouses or greenhouses with auxiliary heating equipment. Such as variable leaf wood, flower leaf taro, taro, pineapple, pepper grass, colored leaf grass, rich bamboo, fish tail sunflower, Brazilian iron, wealth tree, reticulate grass, red (green) gemstone, hulk, green emperor, silver queen, Milan, Cymbidium, Phalaenopsis, Cartland, Oncidium, Magnolia, gold tree, South American iron tree, desert rose, pink, poinsettia, golden bract, coral flower, etc., during the very cold period. From 4: 00 p.m. to 9: 00 p.m., it is appropriate to cover the grass curtain on the roof of the greenhouse, and the grass curtain can not be stopped until the temperature turns warm. In very cold days, it is necessary to strengthen the inspection of heating facilities and personnel on duty, especially from 5 o'clock to 6 o'clock in the morning, do not cut off the fire and power, otherwise it is easy to cause freezing damage to the plants. For those more hardy species of potted flowers and bonsai, such as Chimonanthus praecox, plum blossom, begonia, Yingshanhong, pomegranate, elm, sparrow, oak, crape myrtle, wisteria, yellow poplar, Luohansong, triangular maple, cypress, round cypress, summer cypress, Platycladus orientalis, small bayberry, Chinese wolfberry, holly, opposite section white wax, etc., can be buried together with flowerpots, when not less than-10 ℃, generally will not occur frost injury In particularly cold weather, cover with plastic film or soft grass to keep warm.

It is worth noting that whether it is placed in a greenhouse, in a greenhouse, or at home for potted flowers or bonsai, including ornamental fruits and foliage plants, in addition to maintaining the appropriate temperature, we should also do a good job of ventilation and ventilation. Doors and windows can be opened around noon when the temperature is highest in the day to prevent falling flowers, leaves and fruits. When giving ventilation, we must also try our best to avoid cold air blowing directly on the plant.

In January, special attention should be paid to the inspection of greenhouses and greenhouses in the process of air-conditioning going south, and glass breakage and film tearing were found, and leakage plugging should be carried out in time to avoid freezing the potted flowers. In the greenhouse to provide coal, gas, oil heating, should also be carefully checked, there should be no air leakage, smoke leakage into the greenhouse or greenhouse, in order to prevent falling flowers, leaves and fruits caused by smoke damage.

In order to promote peony blossom during the Spring Festival, potted peony can be placed in a greenhouse, heated to 18 ℃ to 25 ℃ during the day, and kept at about 10 ℃ at night, adding 4 to 5 hours of light every day (incandescent light). It is expected to blossom before and after the Spring Festival. Potted plum blossoms, wax plums, camellias, camellias, camelli Potted hyacinths, tulips, daffodils and freesia, which have been placed in the greenhouse in December, will strengthen the management of water and fertilizer and are expected to be used for decoration and display during the Spring Festival. [page]

four。 Watering

In the watering management of potted flowers in January, the most important thing is to pay attention to the temperature of watering and spraying water, that is, to keep the water temperature roughly consistent with the soil temperature. if the gap between them is too large, it is easy to cause adverse reactions of potted plants. even make the plant deciduous, rotten root or death. Watering time is best arranged for 2 to 3 hours before and after noon. Secondly, according to different plant species, determine the number, times and methods of watering. For most of the potted flowers and bonsai placed in the greenhouse, greenhouse and bedroom, it is appropriate to keep the potted soil moist, and those with low temperature should reduce watering correspondingly. When the temperature rises, the amount of water can be increased and foliar spray can be given. For most foliage plants, we should not only keep the basin soil moist, but also pay attention to spraying water on the leaves, and always keep the leaves of the plants clean. For the species of foliage plants that are not very cold-resistant, such as Fendai leaves, taro, taro, variable leaf trees, etc., when the air temperature is close to the lowest temperature that the plant can bear, the amount of water should be specially controlled. For those species of potted flowers that will blossom before and after the Spring Festival, such as camellia, tea plum, Belgian rhododendron, poinsettia, melon and leaf chrysanthemum, wax plum, plum blossom, primrose, hyacinth, longevity flower, calendula, etc., and ornamental fruits such as firethorn, daidai, bergamot, lemon, rich seed, kumquat, golden bean, winter coral, not only to keep the potted soil moist, but also to spray water on the plant to facilitate the expansion of flower buds. It can also increase the bright color of the fruit.

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

For newly planted green trees and flowering shrubs, they should be checked frequently and watered in time, especially for those evergreen ornamental plants after transplanting, they should also be sprayed properly around noon to prevent the leaves from shrinking and falling off due to excessive air dryness.

five。 Fertilizer application

For most of the green trees and flowering shrubs planted on the ground Such as Begonia, Magnolia, maple, gardenia, seven-leaf tree, camphor, Linden, crape myrtle, Lingxiao, sweet-scented osmanthus, wax plum, plum, cherry, cherry-free, acacia, Luan, palm, Schima superba, runnan, purple tree, camptotheca, peony, golden bell, yellow poplar, grape, coral tree, rose, hydrangea, red leaf plum, Yu Li, elm leaf plum, horse Liriodendron wood, Shu Shu, Prunus mume, Muxiang, du Ying, Golden Salix, hanging Elm, Cryptomeria fortunei, Cryptomeria fortunei, Cedar, Robinia pseudoacacia, Robinia pseudoacacia, White Silk Plum, Hibiscus, clove, crape myrtle, Photinia, Phyllostachys pubescens, Pomegranate, Loquat, etc. If the fertilization task is not completed in December, cake fertilizer, barnyard manure, pond mud and septic tank cleaning materials can be buried on the periphery of the tree root system while the soil is turned over, so as to lay a good material foundation for the growth and flowering of spring.

Potted flowers placed in a greenhouse of about 10 ℃ to 15 ℃, such as Belgian rhododendron, shrimp flower, golden bract, Ruixiang, melon and leaf chrysanthemum, primrose, cyclamen, red mouth daffodil, tapered begonia, hyacinth, tulip, colorful pineapple, orchid, orchid, crab claw orchid, etc., can continue to apply low concentration of potassium dihydrogen phosphate solution, in order to facilitate plant growth and bud blooming.

For most of the potted plants, foliage plants and bonsai put in the greenhouse, as the plants are dormant in winter, fertilizer should be stopped, otherwise it is easy to cause rotting roots of the plants to die.

six。 Pruning

Continue pruning hedges, green walls and balls that have not been pruned in December, and continue pruning flowers and shrubs that have not been pruned in December, such as rose, crape myrtle, wood incense, Lingxiao, wisteria, abundant rose, camphor, Fatong, Chinese tallow, heather, pomegranate, red leaf plum, papaya, wax plum, plum blossom, palm, grape, etc. After pruning, base fertilizer is applied to the periphery of the root system to meet the needs of its spring growth.

According to the original composition requirements, bonsai plant species dominated by shearing and supplemented by pruning, such as hammer elm, sparrow plum, triangular plum, Fujian tea, oak, white wax, bayberry, Elaeagnus angustifolia, pyracantha, June snow, juniper, etc., can continue to be adjusted and trimmed according to personal aesthetic taste to lay a good foundation for the growth and formation of spring. At the same time of pruning, plants that have not changed pots for many years can be changed.

seven。 Pest control

The trunk or big branches such as crabapple, plum blossom, elm leaf, papaya, loquat, blue peach, cherry blossom, red leaf plum, etc., can be sawed off by red-necked longicorn beetles, and the sawed stems and branches can be burned.

Cleaning up the leaves under the trees such as rose, rose, grape, crape myrtle and so on, and burning them centrally after collection can reduce the occurrence of leaf diseases in the coming year.

On the trunk and branches of Haitong, Fatong, privet, firethorn, persimmon, gardenia, plum blossom, red wax scale, cotton blowing scale, shield scale, sagittal scale, pink scale, line scale, etc., spraying and killing with high concentration of quick culling, quinathion, parathion, stone sulfur mixture can effectively inhibit the occurrence of scale insects in that year.

Powdery mildew on melon-leaf chrysanthemum in greenhouse and Botrytis cinerea on primrose leaves can be controlled with thiophanate-methyl to prevent it from spreading to other plants.

To carry out comprehensive control of scale insects and coal pollution on daidai, bergamot, kumquat and other plants in the greenhouse, first wipe off the coal spots on the leaves and the insects attached to the dry branches with a wet cloth, and then spray pesticides such as dimethoate.

Botrytis cinerea on cyclamen plants in the greenhouse can be sprayed 1000 to 1500 times with 50% prohydantoin (mainly composed of isocarbamide) wettable powder.

eight。 Compost fertilizer

Pour rapeseed cake, bean cake and tea seed cake into a pool or tank for soaking and fermentation, so as to provide pot flowers for pouring during the growing season; layer-by-layer accumulation of withered grass, branches, fallen leaves, etc., with garden soil, ignition and burning, self-made burning soil, which can be used as covering soil for sowing and breeding in spring; mixing barnyard manure, pond manure, smoke powder, chicken feces and pigeon dung with garden soil for composting and fermentation can be used as fertilizer for preparing culture soil.

nine。 Ploughing and freezing

The nursery land that has not been reclaimed in December can be ploughed in the first ten days of January. while ploughing the garden, cake fertilizer, compound fertilizer and soil fertilizer are applied, and after freezing over the winter, ditches are made to make beds in early spring for sowing and planting seedlings.

Because January is particularly cold, the plant species suitable for styling must be those with soft branches, good toughness, ginkgo, melon seeds, yellow poplar, velvet cypress, cypress in June, snow in June, cypress, cypress, five-needle pine, yellow pine, black pine, bayberry, canary, wax petal, weeping spear, banyan, wisteria and so on. After modeling, it is best to put it indoors or in a simple plastic greenhouse, and then move to the outside after the air is warm in spring, which is conducive to the healing of damaged parts.

For the plants shaped with brown rope or wire 1 or 2 years ago, if obvious constriction is found in the binding site, the original ligature should be removed and flat traction should be carried out again.

In January, the management of some shallow pot tree stump bonsai, shallow basin landscape bonsai and small, miniature bonsai should be strictly strengthened. Small and miniature bonsai should be buried on the indoor sand bed; tree stump bonsai should prevent the basin soil from freezing, injure the hairy roots of the plant, cause the disintegration of man-made cemented rocks, and prevent the plants planted on the pebbles from withering after being frozen, it is appropriate to put them in an ice-free place and water and spray them regularly to ensure that they can survive the winter safely.
