Propagation methods and management points of coral vine

The florescence of coral vine is from March to December, and the flowering period is very long, so it is one of the flowers with ornamental value. The difficulty of artificial cultivation of coral vine is not high, it is cultivated in Taiwan, Hainan, Guangzhou and other places in China, and it has a good name of "after the vine".

Coral vine

Coral vines can be sown or cut, but mainly by sowing. Because it is not resistant to transplantation, it is better to use live broadcast or pot sowing.

The suitable period is from spring to summer, and the optimum temperature for germination is about 22-28 degrees. Soak the seeds for 4 hours and 6 hours before sowing, make them fully absorb water, then bury them shallowly in the soil for about one centimeter, maintain humidity, and rooting after about 30 days.

Spring is the suitable time for cutting. Generally in spring or autumn, new shoots or stem segments without budding are cut as cuttings with a length of 5-8cm. Remove the lower leaves, leave only the upper 2 murine leaves, insert them into the culture soil mixed with peat soil and coarse sand, pour enough water, then cover the flowerpot with a plastic bag, put it in the semi-shade, and take root after 15 mi for 20 days. The new leaves can be transplanted after growing, but the rooting rate and growth rate are not as good as those of sowing.

Key points of management of flower culture in December

Key points of flower culture management in December 1. The types of flowers that can be sown in the greenhouse in December are: big rock tree, asparagus, gentleman orchid, bulb begonia, cyclamen, winter coral, African chrysanthemum and so on. The types of flowers and trees that can be picked or planted outdoors or stored in sand are: rose (such as Elizabeth), Phyllostachys pubescens, rich seeds, holly, fiery thorns, palms, privet, camphor, lobular privet, disease-free, heather, cypress and so on.

2. 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 (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 cultivated in leaves; combined with pruning, mulberry, geranium, lotus flower, epiphyllum, gemstone, stone lotus, purslane, rooting, longevity flower, golden bract, shrimp flower, 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 nursery bed, you can also cultivate gardenia, Jinxin (Phnom Penh) boxwood, ten meritorious services, hypericum, Admiralty, Yingchun, Luohansong, Luohanbai, June snow, firethorn, silver bud willow, three branches and so on. In addition, branches such as Lingxiao, cloves and grapes can be cut for sand storage and cut again next spring.

3. Excellent varieties of grafted plum blossom, such as bone red and cinnabar, can be used in December to dig up the rootstocks and split or cut the rootstocks, 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 seep into the joint when watering, cover the plastic film to keep warm and moisturize, and then remove the covered plastic film in spring after the scion sprouts. 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. The feasible species of flowers and trees for striping culture in December are: Luohansong, plum blossom, camellia, sweet-scented osmanthus, Michelia mollissima, pedicel begonia, purple magnolia, snowball, brocade, gardenia, spring, golden bell, eight immortal flowers, hemp leaf hydrangea, Qionghua, snow spray, pomegranate and so on.

The offspring at the base of the ramet cut from the large colored leaf pineapple must be small plants that have grown on the mother plant for three or four months, otherwise the color bands of the cut offspring are easy to disappear, which should be paid special attention.

The species of woody ornamental plants that can be cultivated in December are: southern bamboo, hypericum, ten meritorious plants, begonia, brown bamboo, safflower spiraea, golden finch, golden bell, Yingchun, Jasmine, jasmine, magnolia, gardenia, sisal, Phoenix tail bamboo, Phyllostachys pubescens and so on.

6. the grass flower seeds that can be harvested in December are generally the species of grass flowers that are transferred to 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.

7. Transplanting and planting 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. Key points of flower management in July

Weather characteristics in July: on July 7, the Meiyu weather ended in the Jianghuai region. Ambush on July 16 and ambush on August 15, most parts of the country entered the hottest period of the year. The monthly mean temperature in July is more than 24 ℃ in most parts of China and 28 ℃ in the south of Jianghuai. Only the average temperature in the north of Northeast China and Qinghai-Xizang Plateau is below 20 ℃. The management of flower events in July mainly includes the following contents:

I. Flower culture

1. Sowing seeds

The grass flowers that can be sown in July are: melon leaf chrysanthemum, spring of the four seasons, kale, bluebells and so on. When sowing, we should pay attention to moisturizing, shading and increasing ventilation and light transmission.

In July, mature fruits such as plum, hairy peach, mountain peach and elm leaf plum can be picked, washed and sown, or the washed drupe can be stored in wet sand to the crack before sowing. Wintersweet seeds can be sowed as they are picked, and the seeds removed from the fruit sac can also be dried and stored for sowing in the following spring, which will not affect its germination rate.

two。 Cuttage

Rubber tree, Qionghua, Tianmu Qionghua, yellow poplar, Yuanhua fruit, purple magnolia, sweet-scented osmanthus, rhododendron, camellia, tea plum, dragon claw willow, golden willow and so on. Guding flower can also be cut with scales.

In addition, some flowers and trees can be raised by water insertion in July. They are: gardenia, oleander, rose, jasmine, pearl orchid, fig, pomegranate, inverted golden bell, crape myrtle, hibiscus and so on. To cultivate flowers and trees by water cutting, one is to have a foam plastic board with a thickness of 1 cm to 2 cm, which is used as a cutting fixing material after perforation; the other is to keep the water quality of the cutting water clean and put a few pieces of charcoal into it for anticorrosion.

3. Grafting

Annual mountain peach and hairy peach seedlings can be used as rootstocks, budding to cultivate green peach, Shouxing peach, red leaf peach, plum blossom, elm leaf plum, red leaf plum, beautiful plum, etc.; cuttings of wild rose, pink rose and "ten sisters" are used as rootstocks, budding cultured varieties rose, cut rose and rose; potted Magnolia and Magnolia seedlings are used as rootstocks, and Magnolia magnolia and Magnolia magnolia seedlings are used as rootstocks The 2-year-old seedlings of Chimonanthus praecox can be used as rootstocks, and the seedlings of 2-year-old Chimonanthus chinensis can also be used as rootstocks. Grafting is carried out at a distance of 3 cm to 4 cm above the ground, and whether it survives or not can be judged after 7 to 10 days. "Purple Butterfly" and "Jade Butterfly" in rhododendron are used as rootstocks to cultivate Belgian rhododendron or rhododendron by split or abdominal grafting. Cherry seedlings were used as rootstocks, excellent varieties of cherry blossoms were cultured by budding, current-year seed seedlings of bauhinia, Hubei begonia or weeping begonia and begonia flowers were used as rootstocks, T-shaped buds were grafted to cultivate excellent varieties of begonia. Acer maple seedlings were used as rootstocks and bagged grafting to cultivate red maple, feather maple and other seedlings.

The seeds of flowers and trees that can be harvested in July are: wax plum, plum, hairy peach, mountain peach, elm leaf plum and so on.

two。 Transplanting, planting and potting

July is the main period of time for Chen to put grass flowers on the pot during the National Day, when the grass flowers transplanted into the pot can be sowing seedlings or cutting seedlings. After three months of careful maintenance, they bloom just during the National Day period for holiday decoration. They are mainly: a string of red, early chrysanthemum, thousand-day red, Xiaoli, Guinean impatiens, Longkou flower, marigold, peacock grass, ground skin, chrysanthemum, sulfur chrysanthemum, cockscomb and so on.

Tree transplanting is generally not carried out in July, but in some special cases, it is also feasible to transplant some flowering shrubs with soil balls, such as ten meritorious works, hypericum, golden leaf privet, red leaf Berberis, peach leaf coral, dragon cypress ball and so on. However, it is necessary to prune pertinently, set up a shed for shade in time, and increase the number of water spraying, and then transfer to normal management after its basic survival. We must not be careless.

III. Flower management

1. Watering

The flower species that enter the semi-dormant state at high temperature, such as safflower sorrel, geranium, golden bell, gentleman orchid, calla lily, begonia, sedum, longevity flower, cactus, crystal cactus, big flower rhinoceros, emerald beads, big string moon, Ruixiang, crab claw orchid, purslane tree, aloe, etc., due to high temperature, their growth activities basically stop and their metabolic level is very low. Watering should be reduced to keep the basin soil moist. And pay attention to shading and ventilation to create a relatively cool environment. If too much watering, it is easy to lead to rotten roots, but also seriously affect the recovery of its growth after autumn.

The species of flowers that entered deep sleep at high temperature, such as cyclamen, Lycoris, buttercup, purse peony and so on, showed that the aboveground stems and leaves withered, the underground nutrient fibrous roots withered, and spent the summer dormant in the soil with underground stems or tubers. For deep dormant flowers, stop watering, move to a cool place, and keep the pot soil not too dry.

For exuberant flower species, especially foliage plants, such as cycad, Magnolia, tortoise back bamboo, rubber tree, Magnolia, jasmine, Milan, pearl orchid, southern sequoia, bamboo taro, taro, red (green) gemstone, hulk, green emperor, green queen, pink leaf, Brazilian iron, rich tree, camellia, tea plum, peach leaf coral, torch fruit, daidai, lemon, Luohan pine, pomegranate, bauhinia, wisteria, rose, etc. It is not only necessary to increase the amount of water and times of watering, but also to give foliar spraying water and the combination of spraying and pouring properly. Especially when it comes to continuous cloudy days, due to the high temperature and dry air, it is also necessary to give watering and spraying, and must not be negligent. Once it is found that the basin soil is too dry and the leaves wilt, water should be sprayed on the leaves first, and then the roots should be watered after the leaves are erect again. Do not water the roots violently, otherwise it is very easy to cause the woody flowers to "fall green leaves", or lead to the rot of the vegetative fibrous roots of the plants, or even cause the death of the plants.

For potted plum piles, as the flower bud differentiation period is from July to August, appropriate "buckle water" should be given to promote the normal differentiation of flower buds. The method is to keep the leaves of pot plants curled inward slightly in order to control vegetative growth; if the vegetative growth of branches can not be controlled, only one leaf at the base can be cut off when 2 or 3 leaves are pulled out from the second shoot, and flower buds can still be differentiated in the axils of this leaf.

In July, watering potted flowers should avoid a few hours before and after noon, and it is appropriate to water before 10:00 and after 4 p.m., so as not to affect the growth of potted ornamental plants. If you encounter continuous rain this month, you should check the flowerpot in time after the rain, pour it when you find stagnant water in the flowerpot, and loosen the soil once after the pot soil dries up, so as not to cause rotting roots of potted plants.

two。 Fertilizer application

There are four types of ornamental plants that should be strengthened in July. First, the flowering period is particularly long, from spring and summer to autumn, such as Magnolia, rose, Milan, jasmine, etc.; second, the species of autumn flowers, such as chrysanthemum, sweet-scented osmanthus, hibiscus, etc.; third, the species of viewing flowers and fruits in winter, such as hawkdai, bamboo, wax plum, rhododendron, etc.; fourth, foliage plants, such as brown bamboo, tortoise back bamboo, spring feather, rubber tree, and so on. For the first three types of fertilization, in addition to the necessary nitrogen fertilizer, appropriate amount of phosphorus and potassium fertilizer should be applied to meet the overall needs of plants for nitrogen, phosphorus and potassium, and to provide adequate nutritional guarantee for their budding, flowering and fruit hanging; for foliage plants, it should be based on thin cake fertilizer or urea. In the method of fertilization, it is better to apply thin liquid fertilizer.

The grass flowers that should be fertilized in July are: a bunch of red (white, purple, pink), cockscomb, chrysanthemum, hundred-day red, thousand-day red, chrysanthemum, black chrysanthemum, petunia, golden bracts, shrimp flowers, Jianlan, marigold, purple jasmine, longkou flower and so on. Woody flowers are: crape myrtle, pomegranate, poinsettia, Michelia, sweet-scented osmanthus, camellia, tea plum, Fusang, jasmine, Prynne, Milan, evening incense, rose, begonia, mandarin duck jasmine, triangular plum, rhododendron, pearl orchid, wax plum, hibiscus, hibiscus, hibiscus and so on. There are many kinds of foliage plants, such as pineapple, Brazilian iron, brown bamboo, southern fir, synthetic taro, bamboo taro, hulk, ruby, cycad, rubber tree, tortoise back bamboo, Zhu banana and so on.

In July, fertilization must be stopped for dormant or semi-dormant ornamental plants, especially for those succulent ornamental plants, such as sedum, fairy pen, pine chrysanthemum, leopard skin flowers, etc., to prevent plant decay.

3. Pruning, picking buds

The ornamental plants that can top and sprout in summer must be species with exuberant growth, strong germination and resistance to pruning. Heart-picking refers to the direct removal of tender tip buds with fingers. The main bonsai plants suitable for heart-picking are: hammer elm, sparrow plum, Chinan, silk cotton wood, melon seed yellow poplar, wax plum, firethorn, Luohan pine, Tamarix, Elaeagnus angustifolia, banyan tree, white wax, maple, crape myrtle, June snow, Jiuli incense and so on. Pruning refers to the use of scissors to trim off part of the new shoot to promote the germination of the lower lateral buds to form a beautiful crown or tree shape. Most of the species of bonsai plants suitable for pruning are woody ornamental plants that are not easy to pick with their fingers, such as juniper, Platycladus orientalis, Sabina vulgaris, cedar, oak, cat thorn, cypress and so on.

For those potted flower species that bloom continuously for a long time, such as Milan, rose, jasmine, pearl orchid, etc., the stump should be picked in time, and the branches that have flowered should be shrunk in time, which can promote the germination and re-flowering of the lower lateral buds, while for rhododendron, camellia, tea plum, begonia, wax plum, plum, etc., the overlong branches of the crown should also be shrunk in order to form a better crown shape.

4. Shade

July is the month with the strongest sunshine and the highest temperature of the year, so special attention should be paid to shading management for potted ornamental plants.

For those ornamental plants that like shade or semi-shade, they must be placed under the shade to avoid damage to plants caused by the scorching sun. Such as ferns, hairpins, purple calyx, tortoise back bamboo, camellia, tea plum, rhododendron, pearl orchid, crane orchid, orchid, palm bamboo, rubber tree, red (green) gem, spring feather, pink leaf, green apple, pepper grass, orchid, hanging bamboo plum, Brazilian iron, unicorn leaf, pineapple, bamboo taro, auspicious grass and so on.

For the species that like the light, you can give enough light, such as pomegranate, wisteria, crape myrtle, pyracantha, jasmine, June snow, cycad, round cypress, Platycladus orientalis, peach blossom, plum blossom, wax plum, hammer elm, sparrow plum, triangular maple, black pine, bayberry, oak, golden pine, blue orchid, Milan, rose and so on. On the other hand, it is necessary to give proper shade to Luo Han pine, bamboo and cypress, Michelia mollissima, tiger thorn, cloud bamboo, Guanyin bamboo, five-needle pine and so on.

For small, miniature and shallow bonsai, because the temperature is too high this month and the air is relatively dry, in addition to giving necessary shade, flowerpots must also be buried in wet sand, which can reduce evaporation on the surface of potted soil and help to protect the nutrient fibrous roots of plants.

5. Flowers in the air-conditioned room

In an air-conditioned room, you should choose flowers with a higher degree of leathery leaves, or with thicker cuticle, slightly resistant to dry environment, and more resistant, such as rubber tree, star anise plate, ten merit, cycad, Nanyang fir, golden sunflower, sunflower, palm bamboo, Canadian jujube, pineapple, spring feather, tortoise back bamboo, goose palm wood, one-leaf orchid, peach leaf coral and so on. It is not suitable to choose kidney fern, colored leaf grass, hulk, taro and so on. In addition, in the management, attention should be paid to the combination of watering and spraying, and away from the air outlet of the air conditioner, so as to prevent the wind from directly attacking the plant, resulting in the withered tip and scorched edge of the leaves.

6. Pest control

When the new bud of ⑴ orchid spreads its leaves in July, the leaf tip is easy to be infected with anthracnose, which gradually spreads to the whole plant, and in serious cases, it will lead to plant wilting and death. The disease may occur all the year round, poor ventilation, high temperature and humidity, continuous rain, it is more conducive to the breeding and spread of bacteria. Ventilation should be strengthened and 75% of chlorothalonil wettable powder 800 times or germicidal Dan 500 times should be sprayed during the onset period for prevention and treatment.

⑵ when plum blossom, peach blossom, begonia, red leaf plum, cherry blossom, elm leaf plum and other stumps or trunk, red-brown sawdust feces build up, mostly caused by longicorn beetle larvae, which can be controlled by artificial killing, injecting inhaler pesticides, plugging poison labels, burying carbofuran and other methods, which can effectively kill the larvae in the trunk. Pay attention to the injection of pesticides, do not use dimethoate, omethoate and so on, in order to prevent drug damage.

In July, ⑶ should timely control the wild borer of Euonymus tomentosa, Populus tomentosa, Populus tomentosa and Populus tomentosa. When the insect occurs seriously, it can gnaw off all the leaves. Once found, pesticides such as trichlorfon, dimethoate or permethrin can be sprayed in time. If a certain pesticide has been used for a long time, it has produced resistance and can be changed to a new type of pesticide.

In July, some areas of ⑷ will continue to see the leaves of citrus butterfly larvae harming new shoots, such as daidai, kumquat, golden bean, bergamot, lemon, fragrant circle, rue and so on.

⑸ harms ash insects of Ligustrum lucidum, Ligustrum lucidum, water wax and ash trees. The emergence period is from late July to late August. It is necessary to choose the right time to spray pesticides such as quick culling to prevent the disease from happening again in the coming year.

⑹ Japanese tortoise wax scale is the main pest that harms Populus tomentosa, Fawu, Haitong, Camellia, red leaf plum, cedar and so on. When it is serious, it is often covered with branches and leaves. The nymph hatching period is in the first ten days of July, which can be controlled by spraying dimethoate and quick killing pesticides in time.

Fourth, bonsai modeling

In July, due to the high temperature, low air humidity and the vigorous growth of plants, it is difficult to recover from infection after branch injury, so most species of tree stumps are no longer suitable for flat binding. Still can carry on the modelling is some adaptable, tolerant plant species, and the request is the spring pot refines the seedling or the plant planted on the ground. They are: Yingchun, Ginkgo biloba, Luo Hansong, Luo Hanbai, Cuibai, June snow, black pine, melon seed yellow poplar, bayberry and so on.

In July, the modeling of the plant should be careful, light and slow, slowly, not eagerly, too hard, otherwise it is easy to cause the branch and stem of the plant to break, endangering its survival.

Solar terms in mid-July: Lesser Heat on July 7th and Greater Heat on July 22nd.
