The scientific name Jasninon nudiflonw Lindl is also known as Spring Blossom, Golden Plum, Golden Belt, and Chuanxuan. It belongs to the small yellowaceae family 0leaceae Jasmine genus asmuw is geographically distributed as a temperate tree species, originating in northern my country. Northwest, southwest. Shandong, Henan, Shanxi, Shanxi, Gansu, Sichuan. It is widely distributed in Xizang, Yunnan, Guizhou and other places. It is now widely cultivated in the north and south.
Morphological characteristics Deciduous shrubs, with a plant height of up to 3 meters, and an artificially cultivated strand height of less than 1.5 meters, upright or tenant. The branchlets have four fusiform shapes, green, with more or less Di wings on the branches, and the branches are long and slender and Hong shaped. The leaves are opposite, with three compound leaves. The surface is smooth and full. Leaf rachis has wings, petiole is 3 - 10 mm long: small leaf blades are ovate, long ovate or elliptical. The handle is rounded, the apex is sharp or sharp, with a mucronate, the base is cuneate, and the leaf margin is reflexed: the terminal small leaf blade is larger, 1-3 cm long and 0.3 - 1.1 cm wide, sessile or the base extends into a short handle. Lateral leaflets are 0.6 - 2.3 cm long and 0.2 - 1 cm wide. Flowers are solitary in the leaf axils of the last year's branchlets and sparsely on the top of the branchlets: bracts are leaf-shaped, lance-shaped, ovate or elliptical: pedicel is 2 - 3 mm long: flower is green, with 5 - 6 lobes. Narrow-lanceolate, apex sharp: corolla yellow. The length is 2 - 2.5 cm, the corolla tube is 0.8 - 2 cm long and 3 - 6 mm wide, gradually expands upward, splits into 6 pieces, the lobes are oblong or finely rounded, and are 0.8-1.3 cm long. Apex acute or obtuse: stamens 2, inserted in corolla: ovary 2-loculed. Flowering period is from March to April and usually does not bear fruit.
Ecological habits are light-loving, slightly cold-resistant, slightly cold-resistant. They can overwinter in the open field from North China to Northwest China. They require a warm and humid climate, loose, fertile and well-drained sandy soil layer, and grow vigorously in acidic soil, and poor growth in acidic soil. The front force of the roots is strong, and the parts of the branches that touch the ground are easy to take root, which is afraid of waste.
National forest use winter jasmine is named because it blooms earliest among all flowers, and after the flower, it welcomes spring with a hundred flowers blooming. Together with plum blossoms, narcissus and camellia, it is collectively called the "Four Friends in the Snow" and is one of the most precious flowers in my country. The winter jasmine branches have long and weak sides. Music or climbing, the branches and leaves are green and the colors are golden. Gardening should be planted in clusters and on the lake. By the stream. Bridgeheads and corners of walls. Lawn. Green pipes can also be planted on forest edges and sloping terraces. Garden greening can be planted around the room type and on the edge of the front stage. T: Don't apply to hotels. Building ceiling layout. You can also plant plants, move old perennial piles into the pot to make pots into mouths, or change branches into various shapes. It can also be used as a vase for cut flowers. Flowers, leaves. The twigs can be used as medicine.
Where does the spring jasmine grow?
Breeding and cultivation 1. Seedling breeding: use cuttage and layering. Plant reproduction.
(1) Cuttage propagation: Cuttage is mostly carried out in hotbeds. You can also cut directly in the open field. In early spring, select strong annual branches as cuttings, with a length of 15 centimeters. The depth of soil treatment of greenhouse cuttings is 1/3. The cuttage cuttings in open field are buried 2 ~ 3 of the soil. Water after planting to keep the soil moist. Take root in 2~3 weeks. When the young roots change from white to brown, they can be transplanted. In the early stage of transplanting seedlings, a sad sun net or reed curtain is needed to follow the shade for 5 to 7 days. The seedling formation rate is high.
(2) Individual breeding: usually in spring. It is carried out in autumn, but it is better to use early spring buds before they move.
(3) Layered propagation: Primrose branches are often crawling and easy to lay, usually carried out about a week after the flowering. When layering. First, cut the cortex of the branches buried in the soil in Europe with a knife to facilitate rooting.
2. Cultivation and management: (1) Pruning: The jasmine flowers form flower buds on the annual branches and bloom in the spring of the following year. Therefore, all flower branches should be cut short after the annual flowering to promote the growth of more new branches and increase the number of flowers. After flowering, cut off the old branches at the base to promote the emergence of new branches, and pick the heart many times from May to July to promote the emergence of autumn shoots to increase the number of flower branches. If immortal flower measures are adopted, you can enjoy flowers in other seasons. The method is to control water in autumn. Move into the greenhouse half a month in advance. Keep the room temperature at 18C ~ 20C, and strengthen fertilizer management.
(2) Disease and insect pest control: Yingfeng flower diseases often have leaf spot diseases and dead branches. You can spray wine with 1500 times of 50% Tuji Special Powder. Insects are harmful to aphids and macrosacs, so they are sprayed with 1000 times 50% cinchophos emulsifiable concentrate.
(3) Cultivation of high-stem spring flowers: Choose water-wax seedlings with a DBH of more than 2 cm as rootstocks, and branches with 8 - 10 cm long as citrus spring flowers in the same year as ears. Select a certain height to perform abdominal techniques when the bacteria are moving in early spring, tie it tightly with a film, and put it in a crab bag. The difference between jasmine and forsythia both belong to the Xylophyllum family and have many similarities. Such as similar flowering times. The flowers are yellow. Both bloom before the leaves, or the flowers and leaves appear together. Therefore, many people mistakenly think that forsythia is the jasmine flower. In fact, the difference between them is very obvious: ① The jasmine flower has a bushy shape and the plants are short. It looks like a very short irrigation technique. The branches grow in disorder and stretch everywhere. It is slender and drooping, grows in an arched shape, and can reach more than 2 meters long, and many plants are about 1 meter high. Branch: Color group green. Four prisms are obvious: the faces are connected to the shape of star shrubs or beautiful trees. Tall, generally 2 meters high, the branches are relatively regular and not easy: drooping, the color of the branches;-generally light brown.
