Chimonanthus praecox is different from Huangmei and Huangmeihua.
Chimonanthus of Chimonanthaceae. Deciduous shrub, about 3 meters high, with opposite leaves, elliptic, ovate or ovate-lanceolate leaves, tapering apex, rounded or wedge-shaped base, 7- 15 cm long, entire and rough surface; Amphoteric flowers, solitary in the axils of annual branches, with short pedicels, yellow, waxy and fragrant, flowering in 65438+February-March.
Cultivated varieties are Chimonanthus praecox; Diesel wintersweet; Chimonanthus praecox is native to central China. It likes sunshine, but it is also slightly tolerant to shade, cold and drought. It is called "Chimonanthus praecox that never dies after drought".
Light loam which is not strict with soil quality and has good drainage is suitable. Li Shizhen's Compendium of Materia Medica records: "Chimonanthus praecox, whose real name is Huang Meihua, is not plum, so it is named because it is similar to plum in fragrance and color.
Flowers: pungent, warm and nontoxic. Relieve summer heat and promote fluid production. "
In the early Qing Dynasty, the reading mirror said, "Chimonanthus praecox is commonly known as Chimonanthus praecox, Huangmei and Feimei. Because it is placed with plum, its fragrance is similar, its color is like beeswax, and the twelfth month is open, so it has its name. " Chimonanthus praecox is also called Huang Meihua, snowflake, wax wood, wax flower and croton flower.
It belongs to Chimonanthus of Chimonanthaceae, a deciduous shrub with a height of 2-4 meters. Branches and stems are square, brownish red, and have oval prominent lenticels.
The bud has many imbricate scales. Leaves opposite, apex acuminate or acute, base rounded or broadly cuneate, elliptic-ovate to ovate-lanceolate, entire.
The flowers and leaves are open and fragrant, with a diameter of about 2.5 cm. Perianth is multi-slice, waxy and translucent; Receptacle oval, about 4 cm long, semi-lignified, capsule-shaped, persistent, covered with filiform hairs, containing several achenes, one seed per fruit.
The flowering period is from February 65438 to February, and the fruiting period is from June to September. Chimonanthus praecox is mainly distributed in the southern part of the Yellow River Basin, cultivated everywhere, and wild in Qinling and Hubei.
There are many cultivated varieties. According to Zhao Tianbang's book Chimonanthus praecox in China, Chimonanthus praecox has four varieties, 12 and 165. Among them, there are pure yellow, golden yellow, light yellow, dark yellow, purple yellow, silvery white, pale white, snow white and yellowish white, and the stamens are red, purple and white.
Among them, the best is Yanling Chimonanthus praecox produced in Yanling County, Henan Province, which is known as "Yanling Chimonanthus praecox is the best in the world". The representative variety is' Suxin Chimonanthus praecox': it is called' Yanling Suxin Chimonanthus praecox' in Yanling literature, and its heart is white and fragrant.
Because it is not completely open, the opening is downward, like "hanging on the golden bell", so it is called Jin Zhongmei. Chimonanthus praecox is a traditional and precious ornamental flower with a long cultivation history and rich Chimonanthus praecox culture.
Li Shangyin, a poet in the Tang Dynasty, called wintersweet Han Mei, and there is a saying that "Han Mei is known through a wild pond". Yao's Remnant Pieces also called Chimonanthus praecox a cold guest.
Chimonanthus praecox is the first flower among all flowers before spring, especially the tiger-hoofed plum, which blooms in October of the lunar calendar, so it is called early plum. Chimonanthus praecox flowers first and then leaves, flowers and leaves do not meet, and branches are thinner when flowering, so it is also called dried plum.
When Chimonanthus praecox blooms, it usually snows, so I want to enjoy Chimonanthus praecox. After the snow, you will walk through the snow, so it is also called Xue Mei. Also called wintersweet, because it blooms in early winter and bears fruit in winter, it is also called winter plum.
Chimonanthus praecox is the best tree species to enjoy flowers in winter because of its unique personality, and it is also one of the first choice tree species for urban beautification, fragrance and air purification. At the same time, Chimonanthus praecox has developed root system, strong growth adaptability and strong rooting and germination, and is an excellent tree species for soil and water conservation, windbreak and sand fixation.
It can be used as a clustered flowering shrub for street greening, and can also be cultivated into small trees as street trees. It can not only form large-scale landscapes such as Meishan, Meiyuan and Meiyu in the park rockery and lakeside, but also form sketches in the lawn plate with broad vision. It can be planted in the open space of the garden and can be free and easy naturally. Can also be bred into carved bonsai, get a wonderful artistic conception, can also be cut into flower arrangements.
Chimonanthus praecox not only has ornamental value, but also was used as a dish or snack in ancient times. Flowers are often used for health care and longevity.
He Guozhen's "Flower Cooking Recipe" lists the varieties of flowers such as wintersweet bean curd soup and wintersweet glass chicken slices. Flowers can also be eaten in other ways, such as air-drying flowers and adding tea leaves to make wintersweet tea, or directly pouring a few flowers into boiling water instead of tea leaves, which has a strong aroma and can stop coughing and relieve asthma.
Flowers can also be used as cooking ingredients, such as fish, shrimp and tofu or soup, which are delicious and fragrant. Chimonanthus praecox contains volatile oil. The oil contains borneol, eucalyptus oil, linalool, myricetin, isorhamnetin, myricetin, a- carotene, linoleic acid, oleic acid and other chemical components. The leaves contain myricetin, myricetin and isorhamnetin. Fresh leaves contain cyanohydric acid.

6. How to raise wintersweet The wintersweet bought in the market is like a branch with some small flowers on it.
Do you seem to be asking how to raise cut wintersweet? After the flower arrangement is cut, it is necessary to extend its viewing period, one is to maintain the balance of water in the branches and leaves, and the other is to sterilize and prevent corrosion.
The main methods are as follows: 1. Cutting flower branches and arranging flowers should be done at the bud and after flowering, otherwise the flowers will wither quickly and the flowering period will be short. Cut flowers should be cut in the morning, inserted into the water while cutting, and placed in the shade to prevent sun exposure and reduce transpiration and water loss.
Secondly, in order to improve the water absorption function of Chimonanthus praecox cuttings, more holes can be broken or opened with a hammer at the base end of the lower 3 cm branch to expand the water absorption surface. Before flower arrangement, the flower branches can be inverted and poured in with clear water from the incision at the base, which can eliminate air, improve its water absorption function and prolong the flowering period.
Third, use preservatives such as peppermint oil, alcohol, acetic acid and dilute hydrochloric acid. The cut at the root of the branch can be preserved. Use 0.
03% aspirin or 0. 0.25% potassium permanganate solution can be used as the medium for flower arrangement of Cymbidium hybridum, which can prolong the flowering period by 3 ~ 5 days.
Add appropriate amount of sucrose, vitamin B 12, boric acid, sulfur, salt, carbolic acid, etc. Adding flower arranging water can not only keep fresh and sterilize, increase nutrition, but also improve water absorption function and inhibit the aging speed of flowers. According to the proportion of 98 ml of sterile water, 2 ml of absolute ethanol and 2 g of sucrose, a fresh-keeping liquid for flower arrangement was prepared, and a small amount of 8- hydroxyquinoline citric acid was added as a bactericide for flower arrangement, and it was changed every 2-4 days 1 time, which could prolong the fresh-keeping period of Chimonanthus praecox flower arrangement by 2-2 times.
Five times.
7. How to successfully plant Chimonanthus praecox? I have a small Chimonanthus praecox, which will be planted indoors.
Potted Chimonanthus praecox, due to the limited potted soil, the soil should be sandy nutrient soil with high humus and loose air permeability.
The temperature should be kept at about -2℃, and the flowering period should not be lower than-10℃. Chimonanthus praecox is afraid of the wind, which will cause rust spots on the leaves due to mutual friction.
Chimonanthus praecox is drought-tolerant. Generally, it is not watered, but it should be watered thoroughly. However, there must be water shortage in summer to avoid the formation of dry white spots on the leaves and affect the formation of flower buds. It is wise to water them thoroughly.
Special attention must be paid to proper watering before or during flowering. Too much watering is easy to drop buds and blossom, and too little watering is not neat. Chimonanthus praecox must be pruned in time after the flowers wither.
-Generally, it is advisable to prune the flowers in time after they wither and before they come out, and cut off dead branches, over-dense branches, cross branches and moth-eaten branches. Leave 2-3 pairs of buds at the base of annual branches, and cut off the upper branches to promote germination and branching. After each new branch grows to 2 ~ 3 pairs of leaves, it should be pitted to promote the germination of short and strong flower branches and make the plant shape symmetrical and beautiful.
Pruning is mostly carried out in March-June and stopped after July. If it is not suitable for pruning, it will take out a lot of long branches, consume nutrients, make the flower buds not differentiate much, and affect flowering.
Chimonanthus praecox likes fertilizer, so you can apply thin fertilizer once a month, and you can't use agricultural fertilizer to avoid "greed for green" after autumn. Topdressing before defoliation in autumn, the ratio of phosphorus, potassium and nitrogen is 2: 1:0.
Five is more appropriate. Chimonanthus praecox is a deep-rooted tree species and must be planted in deep pots.
Potted once every 2~3 years, the topsoil of the soil is removed, so that its root neck gradually emerges from the surface of the pot soil, and its roots are exposed, which is particularly unique. Pest control: Chimonanthus praecox has fewer diseases and more pests, such as aphids, scale insects, thorn moths and leaf curl moths. Aphids suck juice on shoots, scale insects suck juice on branches, and spiny moths and leaf rollers bite leaves, new buds and flower buds.
Prevention should be given priority to, and flowerpots should be placed in an environment with sufficient light and good ventilation to reduce the occurrence of pests and diseases. If the above pests are found, 50% chlorpyrifos 1000 times can be sprayed. In order to reduce the pollution to the environment of flower cultivation, it can also be killed by indigenous methods. For example, scale insects can be killed with acid and vinegar solutions, aphids can be killed with washing powder water, and a small amount can be killed manually.
8. Little knowledge: What plants will bloom in winter?
There are plum blossom, narcissus, snow lotus, camellia, longevity flower, wintersweet, chrysanthemum, begonia, poinsettia, bergamot, rose and so on.
Plants that bloom in winter are generally in the subtropical zone in the south, and there are no real flowers in the snow and ice in the north, so they are frozen. In winter, the crab claw lotus blooms in 65438+February, also known as zygocactus trurncatus.
Some varieties of camellia bloom in June, February and October. Chimonanthus praecox bloomed in June 5438+10, which is also a southern flower. Other flowers, such as plum blossom, which we often say, all bloom in early spring. Tulips and magnolias that bloom early are also in early spring, while irises, peaches, apricots and pears are a little later, which is basically spring. Narcissus was originally a flower in early spring and planted in the ground. In winter, we often keep it indoors for hydroponics, which is a kind of cultivation, that is to say, this is not the flowering period of the plant itself, but the forced flowering of the plant at that time. The natural flowering period of daffodils is in March. You can plant daffodils, hyacinthus orientalis, swallow's paw and Clivia at home. Commercial cymbidium, Anthurium andraeanum, Cyclamen persicum, Phalaenopsis, Crab Claw Orchid, Cyclamen persicum, Clivia, Plum Blossom, Rhododendron, Camellia and Chimonanthus praecox all bloom in winter.
9. How to raise wintersweet?
Plum blossoms in winter are fragrant and cold-resistant. It is an excellent indoor fragrant flower in winter, and can also be cut into flowers for bottle planting during the Spring Festival.
Chimonanthus praecox is a shrub species with strong clustering. Before placing the box, keep a thick main branch in the center of the cluster and cut off other branches from the base. After the pot is put on, cut off the side branches sprouting at the base of the main branch 30 cm, keep three evenly distributed side branches at the top, and cut off the main branch at the same time, so that the three side branches produce robe branches. In the future, a large number of roots and new small side branches will occur every year. In addition to pruning the flower branches in time to promote axillary bud germination and form more flower branches, we should also prune the over-dense side branches and remove all the roots and tillers at the same time to maintain a small tree shape.
Chimonanthus praecox is a deep-rooted plant, which should be planted in deeper and larger flowerpots. Beijing is the critical line for courtyard open cultivation, but it should be planted on the south side of buildings facing the sun and leeward to avoid freezing. Potting must be carried out in areas below the temperature in the north or Beijing, and it is not advisable to enter the house too early in late autumn.
As far as Beijing is concerned, fallen leaves should still be kept outside. At this time, the flower buds have formed and will be moved indoors before the heavy snow comes (65438+February). If the room temperature is high, it will bloom before New Year's Day. If the temperature is low, the flowering period will be delayed until around the Spring Festival.
After flowering, it should be stored in a cold room below 0℃ to prevent new buds and leaves from sprouting prematurely, otherwise the plant will grow in vain, which will affect the differentiation of flower buds and is not conducive to the next year's flowering. Care must be taken to control the amount of watering during maintenance. We want to plant it in a high-lying, dry and well-drained place in the garden, which can grow normally all year round without artificial irrigation, so it is called "Chimonanthus praecox".
When potted, you should master the watering principle of thoroughly drying before watering, but you should always topdress fertilizer to promote the formation of a large number of buds, otherwise flowers will be scarce. Chimonanthus praecox is a positive plant, but it is also tolerant to shade, so it can also be planted on the north side of buildings in warm areas, and it can grow normally as long as it can see oblique light in the morning and evening. After the leaves fall in winter, they don't need enough sunshine.
