Winter jasmine, also known as Spring Festival, Jasminum giraldii, golden belt, has deciduous shrubs. Plant height is 30- 100 cm. Branchlets are slender, erect or arched, drooping, showing a chaotic pattern. 3 leaflets are opposite to compound leaves, and the leaves are ovoid to oblong. Flowers were born on the branches born last year, which opened before the leaves, with a faint fragrance, golden color and a blush outside. The flowering period is from February to April. Named for its earliest opening among flowers, flowers will usher in the spring of flowers. Potted spring has strong adaptability, likes light, cold tolerance, drought tolerance, alkali tolerance and fear of waterlogging. The soil requirement is not high, and it can grow in slightly acidic, neutral and slightly alkaline soils, but it grows best in loose and fertile sandy soil. Planting is usually carried out after flowers wither or in mid-September. If you want to cultivate the root-lifting type, you can raise the root properly when planting, but don't raise it too high at a time, otherwise it will be bad for growth. Since winter jasmine is yellow, light blue, purple and black pots should be chosen when planting, so that the colors of pots and flowers can be coordinated. If cultivated properly, there will be yellow flowers in spring, green leaves in summer and autumn, green vines in winter and spring all year round. Maintain the site. During the Spring Festival, those newly planted or changed pots should be watered, kept in the shade for about 10 days, and then placed in a semi-cloudy and semi-sunny place; Cure for a week, and then put it in a sunny, well-ventilated and humid place for curing. In winter, the pots planted with spring flowers in the south can survive the winter safely as long as they are buried in the soil in the leeward and sunny places, while in the north, they should be moved indoors when the temperature is low (about 5℃) in early winter. If you want to make the Spring Festival blossom ahead of time, you can move it into a sunny room with moderate or high temperature, such as placing it in the sunny place around 13℃, spraying clean water on the branches and leaves twice a day, and it will bloom in about 20 days. If it is placed indoors in the sunny place at about 20℃, it will bloom in about 10 days. Keep the room temperature at about 8℃ after flowering, and be careful not to let the wind blow directly on it, which can prolong the flowering period. After bloom, the higher the room temperature, the faster the flowers wither.

maintenance management
1. Location: Spring Festival, just after planting or changing pots, water them first, put them in the shade for about 10 days, and then put them in the semi-cloudy and semi-sunny places; Cure for a week, and then put it in a sunny, well-ventilated and humid place for curing. In winter, in the south, as long as the pots planted with spring flowers are buried in the soil in the leeward and sunny places, they can safely overwinter, and in the north, they should be moved indoors when the temperature is low (about 5' C) in early winter. If you want to make the Spring Festival blossom ahead of time, you can move it into a sunny room with moderate or high temperature, such as placing it in the sunny place around 13℃, spraying clean water on the branches and leaves twice a day, and it will bloom in about 20 days. If it is placed indoors in the sunny place at about 20℃, it will bloom in about 10 days. After flowering, keep the room temperature around 8' C, and be careful not to let the wind blow directly on it, which can prolong the flowering period. After bloom, the higher the room temperature, the faster the flowers wither.
2. Watering: It is humid in spring, especially in hot summer. Besides watering once every morning, water properly in the afternoon. In order to keep the environmental humidity low, water should be sprayed on the ground frequently. Yingchun is afraid of water in the basin. In rainy season, when it rains continuously, the basin should be put down or moved to a place without rain. In winter, the temperature is low, water evaporation is less and water is less.
3. Fertilization: When planting in the Spring Festival, put a few animal hooves at the bottom of the pot as base fertilizer. In the spring growing season, the decomposed dilute liquid fertilizer should be applied 1 ~ 2 times a month. July-August is the flower bud differentiation period of winter jasmine, so liquid fertilizer containing more phosphorus should be applied to facilitate the formation of flower buds. For example, in the early flowering stage, applying a decomposed and thin organic liquid fertilizer can make the color gorgeous and prolong the flowering period.
4. Shaping: Jasminum nudiflorum has strong germination ability. During the growing period, you should always pick your heart, cut off or shorten some branches to keep the tree shape. After the flowers wither, the branches should be cut short, generally leaving only 2 ~ 3 buds, and the main branches can leave more buds appropriately. After the new branches are born, if they are properly maintained, the buds will be clustered.
5. Pest control: There are few pests and diseases in the Spring Festival, and there are occasional red spiders, which should be removed in time.
How is the winter jasmine suitable for reproduction?
Winter jasmine is so easy to breed that it can grow into new plants when it is slaughtered and scattered in the soil, so the breeding base is large, but the seedlings are a little small. Otherwise, cut, the number is less, but the plant is bigger.
How to breed Jasminum nudiflorum quickly?
Are you looking for information about rapid propagation? Cutting and layering are generally used for propagation, but these methods are not as fast as water insertion.
Water Insertion Propagation of Jasminum nudiflorum
Winter jasmine is cultivated all over China. Because of its strong adaptability to soil, drought resistance, vivid and beautiful plant shape and pruning resistance, it is widely used as a greening material for garden lawn, courtyard viewing and soil and water conservation. The roots and tillers of Jasminum nudiflorum have strong germination ability, and the general propagation methods are cutting and layering. However, this conventional propagation is time-consuming and laborious, and is limited by many conditions. After many experiments, it is a simple, time-saving and labor-saving method to make cuttings take root in water with water as the substrate.
1. Water injection time: it can be carried out all year round. In winter, the water injection container can be placed in a sunny place indoors. Pay attention to shading in summer to prevent sun exposure. When inserting water, the water temperature should be kept at 15 ~ 20℃, and the cuttings can take root quickly and have high survival rate.
Second, the cuttings are inserted into the water: the cuttings are selected to grow strong and full, and the buds are full. The cutting length is generally 8 ~ 12 cm, and 2 ~ 4 sections can be left. Cut it from the flat mouth about 2 mm below the lowest knot and tie it into a bundle every 10. If there are too many leaves in the upper half of the cuttings, they can be removed appropriately to facilitate rooting.
3. Water injection containers: The containers are large-caliber pots or shallow tanks, glass tanks, porcelain tanks and other containers, which should be cleaned before use.
4. Water insertion method: clean rainwater, river water or tap water are filled into the container to a depth of 8/ 10 cm, and then the bound cuttings are arranged in water to a depth of 4-6 cm. Then put the container in a ventilated and semi-cool place outside, and the water quality must be kept fresh and clean, and the water can be changed once every 3 to 5 days. Generally, tumor-like healing tissue can be produced about 20 days after implantation, and fibrous roots can grow about 35 ~ 40 days.
Verb (abbreviation of verb) cultivation: when the fibrous root grows to 3 ~ 5 cm, it must be planted in time, and the operation should be careful to avoid damaging the root. Generally, shading treatment after planting takes about 10 days, which can be managed normally.
Cultivation techniques of winter jasmine
Winter jasmine is a deciduous shrub of Oleaceae, with beautiful branches and beautiful flowers. In addition to being planted in courtyards, flower beds and other places, potted plants can also be used for viewing or making bonsai.
Spring likes sunshine, but also bears shade, cold and drought. No matter soil, pastoral soil, sandy loam soil, slightly acidic or slightly alkaline soil can grow. Potted winter jasmine should be planted in pots after defoliation in winter and before germination in spring. Potted soil should be loose and fertile sand with good drainage and water retention. After planting, water it and maintain it in a sheltered and sunny place. During the growing period, watering should be done "if you don't do it" to avoid water accumulation in the basin, otherwise it will cause rotten roots. After September, it is necessary to reduce watering, control the vigorous growth of branches and make them overwinter safely. After flowering in spring every year, the decomposed organic liquid fertilizer 1 ~ 2 times should be applied topdressing to supplement the nutrients consumed by flowering and restore plant growth as soon as possible. June-August is the flower bud differentiation period, so the amount of phosphorus and potassium fertilizer can be increased and the water should be retained to facilitate the formation of flower buds. Fertilization in autumn can increase the cold resistance of plants and promote the development of flower buds. Applying some fertilizer before flowering can not only make the flowers full, but also prolong the flowering period. Turn the pot every 65438+ for 0 to 2 years after the spring flowers wither. Potted soil can be made by mixing 1 part garden soil, humus soil and sandy soil, and adding a small amount of decomposed cake fertilizer and livestock manure as base fertilizer. Combined with changing pots, pruning plants, except dry branches, pests and diseases, long branches, and pay attention to pinching in the growing period, promote more branches of plants and keep the tree perfect. Because the branches of winter jasmine are slender and soft, they can be woven into basket-shaped, fan-shaped, spherical and triumphant shapes to increase their ornamental value. If you need to blossom on New Year's Day or Spring Festival, you can move the seedling pot to the sunny place indoors three weeks in advance, and keep the temperature at 15℃ to 20℃ to blossom in time. The flower branches of Yingchun can bloom in water for 5 to 7 days. It is an excellent winter cut flower material.
There are many propagation methods of Yingchun, such as dividing plants, layering and cutting. Plant division usually takes place in spring and autumn, but it is better before flower buds germinate in early spring. Usually, layering or cutting is carried out about one week after flowering. When layering, first cut the cortex of the buried branch with a knife to facilitate rooting. Cuttings can be carried out in hotbeds or directly in open spaces. Two-year-old robust branches were selected as cuttings, and the appropriate length was 15cm ~ 20cm. Bury 1/3 branches in the soil, keep the soil moist and take root in 2 ~ 3 weeks. When the young roots change from white to yellow-brown, transplanting begins. In the early stage of transplanting seedlings, sunshade net or reed curtain should be used for 5 ~ 7 days, and the seedling rate is high.
The winter jasmine used for bonsai can be selected from those that have grown for many years and have roots & gt
How to raise the bonsai of winter jasmine, the cultivation methods and matters needing attention of the bonsai of winter jasmine.
1. Soil: The breeding of Jasminum nudiflorum has certain requirements on soil, which requires loose, fertile and well-drained sandy soil, which grows vigorously in acidic soil and does not grow well in alkaline soil.
2. Temperature: In the hot summer sunshine and high temperature, the winter jasmine should be moved to the semi-shade, which is more conducive to its growth. Before and after the Spring Festival, move the flowerpot into the greenhouse or plastic shed, keep the room temperature at about 15℃, and you can see the flowers in about 15 days.
3. Water: Spring Festival is humid. According to the degree of soil dryness and wetness, water 65,438+0-3 times from flowering to flowering. Before the rainy season comes, water it frequently. Don't topdress in the growing season. Don't water after beginning of autumn, lest the branches are too long and tender to survive the winter safely.
4. Fertilization: When planting in the Spring Festival, put a few animal hooves at the bottom of the pot as base fertilizer. In the spring growing season, the decomposed dilute liquid fertilizer should be applied 1~2 times a month. July-August is the flower bud differentiation period of winter jasmine, so liquid fertilizer containing more phosphorus should be applied to facilitate the formation of flower buds. For example, in the early flowering stage, applying a decomposed and thin organic liquid fertilizer can make the color gorgeous and prolong the flowering period.
5. Pruning: Jasminum nudiflorum has strong germination ability. During the growing period, you should always pick your heart, cut off or shorten some branches to keep the tree shape. After the flowers wither, the branches should be cut short, generally leaving only 2~3 buds, and the main branches can leave more buds appropriately. After the new branches are born, if they are properly maintained, the buds will be clustered.
6. Insect pests: There are few common pests and diseases of winter jasmine, mainly aphids. The control method is to spray 40% omethoate emulsion, dichlorvos 1500- 1800 times or use tobacco liquid.
How to make the bonsai of winter jasmine look better
In Shi Sheng Xinyi Botanical Garden, potted plants are very good.
How to raise the bonsai of winter jasmine and how to strengthen the root system of winter jasmine.
The bonsai of winter jasmine needs pruning, adjusting the tree potential, preserving nutrients, making the branches evenly distributed, the crown neat and beautiful, and it is important to facilitate more flowering. Whether the pruning time of Jasminum nudiflorum is appropriate or not is the key link in raising Jasminum nudiflorum.
The buds of winter jasmine are formed on the branches in the first year, so they should not be pruned in autumn and winter. If you prune at this time, you will cut off the branches with flower buds formed in summer, resulting in no flowers to bloom. The most suitable pruning time for the bonsai of winter jasmine is within 10 days after all the flowers wither and two or three buds are left on each branch.
Prune the bonsai of winter jasmine once after flowering in spring, and cut off all the branches of that year, leaving 1-2 tooth holes. After growing for a period of time, then pruning, according to the symmetry of crown branches, cut off weak branches. If the branch grows too fast, you can chop it again in late March or early April, and then wipe a lateral tooth according to the growth direction of the branch after the lateral tooth grows out.
At the beginning of June, cut off the wheel branches, anti-branches and overlapping branches that don't need to be kept, and properly thin the branches that are too dense to facilitate light transmission. Pruning the bonsai of winter jasmine must make the new branches strictly follow the natural law of plant growth and fully reflect the combination of natural beauty and artificial beauty of plants.
After two to three years of pruning and cultivation, an ancient and colorful bonsai of winter jasmine appears in front of us. After the modeling is finalized, the redundant branches and leaves should be trimmed every year to keep the tree shape unchanged.
How to Cultivate Thick Roots of Winter jasmine
1, after planting, water the tree holes with the rooting agent of happy forest and regenerated organisms for 2-3 times, depending on the later situation.
2. Use soil with water and fertilizer conservation, rich humus and good air permeability to improve the living environment of roots.
3. Avoid stagnant water and irrigate scientifically.
4, cold season, pay attention to cold insulation, prevention and control of root freezing injury.
5, after watering for a period of time, appear hardening, should be timely punching breathable, promote root respiration, improve root activity.
6, foliar spraying nutrition regulator, promote photosynthesis, increase nutrient accumulation, * * * root growth.
7. Scientifically adjust the mutual adaptability between soil and trees, so that the soil can meet the needs of the growing environment of trees. (such as saline-alkali land improvement)
How to plant winter jasmine how to plant winter jasmine
Winter jasmine, deciduous shrub, mainly planted underground. Propagation methods include plant division, layering and cutting. The time of ramet propagation can be carried out in spring and autumn. The method is to cut off the small branches at the base of the roots and stems of Yingchun and connect them with the mother plant, and then plant them separately. After planting, you can pour some root-fixing water to improve the survival rate.
Generally, perennial mother plants can be divided into 10 ~ 20 clusters, which can bloom after planting. Winter jasmine flowers first, then leaves. From February to March every year, the flowering period lasts for 3 to 5 months and lasts for 50 days.
