Winter jasmine, also known as golden plum, golden belt and small yellow flower, is a deciduous shrub of Oleaceae. Named after its earliest flowering among hundreds of flowers, it is also called "four friends in the snow" with plum blossom, daffodil and camellia, and is one of the precious flowers in China. Winter jasmine is not only gorgeous in color and extraordinary in temperament, but also has the characteristics of not being afraid of cold, not adapting to local conditions and strong adaptability, and has always been loved by people.

morphological character

Deciduous shrub, slender branches, arched and drooping growth, more than 2m long. The lateral branches are stout, quadrangular and green. The trifoliate compound leaves are opposite, 2-3 cm long, and the leaflets are oval, smooth and entire. Flowers are solitary in leaf axils, with cup-shaped corolla, bright yellow, 6-lobed at the top, or compound leaves. The flowering period lasts for 50 days from March to May.

Ecological habit

Like light, slightly tolerant of shade, slightly cold, afraid of waterlogging, can overwinter in North China and Yanling in the open air, requiring warm and humid climate, loose and fertile sandy soil with good drainage, which grows vigorously in acidic soil and poorly in alkaline soil. The roots germinate vigorously. The landing part of the branch takes root easily.

breeding method

Multipurpose cutting. Select 1 annual branches, cut them into 15cm long, water the whole seedbed, and then cut them. You can also dry-cut, that is, cut the whole seedbed and then irrigate it with water. Cutting can be carried out from the middle of 10 of 65438 to the middle of 10 of 65438 or in spring. After rooting, it can be planted alone, divided into plants or propagated in layers.

Cultivation and modeling

Yingchun forms flower buds on the annual branches of/kloc-0, and blooms in the following spring. Therefore, after the flowers wither every year, all the branches should be cut short to promote the growth of more lateral branches, increase the amount of flowers and strengthen the management of fertilizer and water.

Diseases and pests:

Pests and diseases often occur leaf spot disease and dead branch disease, and 1500 times of 50% bactericidal wettable powder can be sprayed. Insect pests do great harm to aphids and giant salamander, spraying 50% phoxim EC 1000 times.

Gao Qian's Spring Festival Culture

You can choose water wax seedlings with breast diameter above 2cm, and perform abdominal grafting at 1m or a certain height when they sprout in early spring. Take the branches of Jasminum nudiflorum as scions, with the length of 8- 10 cm, and carry out grafting. Then tie it tightly with a film, wrap it in a plastic bag, and gradually tear the bag after the branches survive, so that they can breathe freely to exercise seedlings, pick their hearts to promote side branches and cultivate crown shapes.

Suitable range

Originated in the subtropical regions of South China and Southwest China, it is widely cultivated in South China, and can be grown in North China and Henan, and cultivated in Yanling County.

Garden use

The branches droop, and the flowers bloom first and then the leaves in early spring. The flowers are golden yellow and the leaves are green. It should be arranged at the lakeside, stream side, bridge head, corner or lawn, forest edge and slope in the park. It can also be planted around the house for flower viewing in early spring. Flowers, leaves and shoots can be used as medicine.

Distribution of origin

Originated in northern China, mainly distributed in North China, Liaoning, Shaanxi, Shandong and other provinces. Winter jasmine is cold-tolerant, sunny, drought-tolerant but not waterlogged. Propagation is mainly based on branching, layering and cutting. It is often used to decorate flower beds and gardens. It is an important flower and plant in early spring.

Often cultivated in various places for viewing; It is also distributed in the central and northern provinces of China.

Leaves are used as medicine to reduce swelling and detoxify, and treat swelling, pain, sores and blood stasis; Flowers can relieve fever and diuresis, and treat fever, headache and urinary heat pain. Both leaves and roots contain syringin and geniposide. Reproduction by cutting or layering.

Edit the section on reproduction and cultivation.

Cutting is the main method, and layering and ramet propagation can also be used. Cutting can be done in spring, summer and autumn. Semi-lignified branches, with the length of 12- 15 cm, were inserted into sandy soil, kept moist, and took root about 15. Layering: Bury the longer branches in the sand without being scratched, take root after 40-50 days, and transplant them separately from the mother plant in the next spring. The division of plants can be carried out when they sprout in spring. When transplanting in spring, some overground branches should be cut off and lodging soil should be brought. During the growth process, pay attention to the fact that the soil can't accumulate water and be excessively dry, and properly fertilize 2-3 times before and after flowering. Prune and reshape in autumn and winter to keep more new flowers. Pests and diseases often occur leaf spot disease and dead branch disease, and 1500 times of 50% bactericidal wettable powder can be sprayed. Insect pests do great harm to aphids and giant salamander, spraying 50% phoxim EC 1000 times.

Jasminum nudiflorum likes warm and cold, and it can safely overwinter outdoors in Beijing and its south area, whether planted in ground or potted. Only potted plants can be planted in the north of Beijing, and they will be moved to a low greenhouse (5 ~ 10℃) to overwinter at -5℃. The flowering period of the Spring Festival is affected by the temperature, and1opens from south to north from late October to April. If you want to blossom in the Spring Festival, you can move the flower buds into the sunny room at 12 ~ 16℃ 2 ~ 3 weeks before the Spring Festival, and water them for 3 days 1 time, and often spray water on the branches and leaves. If the flowers don't bloom before the Spring Festival 1 week, the room temperature can be raised to 20.

Edit this paragraph to identify differences.

Both Yingchun and Forsythia suspensa belong to deciduous shrubs of Oleaceae, which are widely cultivated in China. There are many similarities between the two plants. They bloom at the same time, open yellow flowers, bloom first and then grow leaves. So many people can't tell these two plants apart.

In fact, the difference between them is obvious:

1) The old branches of Yingchun are grayish brown, with quadrangular branchlets, slender, arched and green. Yequan is a trifoliate compound leaf, which grows symmetrically in a cross. The leaves are small, oval, entire, and the apex is narrow and sharp. Flowers are solitary, yellow, tall, disc-shaped, and inserted between the axils of annual branches. Forsythia suspensa branches are round, the branchlets are light brown, the stems are hollow, often drooping, the leaves are large, the shape is rectangular, the upper part is serrated neatly, and the lower part is full. Single leaf or 3 pairs of opposite leaves, in which the top leaf is larger and the two sides are smaller. These flowers are golden yellow with wide petals.

2) The branchlets of Yingchun are green, and those of Forsythia suspensa are dark in color, generally light brown;

3) Each flower of Jasminum nudiflorum has 6 petals, while Forsythia suspensa has only 4 petals;

4) Jasminum nudiflorum rarely bears fruit, while Forsythia suspensa bears fruit.
