Breeding methods of Jasminum nudiflorum (basic knowledge)
The best propagation time: the cutting of Jasminum nudiflorum can be carried out from mid October to mid November or in spring.
The best growing soil: the culture of Jasminum nudiflorum has certain requirements for the soil, which requires loose, fertile and well drained sandy soil to grow vigorously in the acidic soil, but poor in the alkaline soil.
Growth humidity requirements: spring like wet, especially in the hot summer, in addition to watering once a day in the morning, in the afternoon should also be appropriate watering. In order to maintain the humidity of small environment, water should be sprayed to the ground frequently.
The best growth temperature: when the hot sun and high temperature appear in summer, it is better to move the Jasminum nudiflorum to half shade. Before and after the Spring Festival, the pot will be moved into the greenhouse or plastic greenhouse, room temperature maintained at about 15 ℃, about 15 days to see flowers.
The best growth light: Jasminum nudiflorum should have more light before flowering, which is very important for pregnant bud flowering. But when blooming, it doesn't need direct sunlight. It should be put in the half shade of the room.

Precautions for breeding Jasminum nudiflorum
Fertilizer application:
1. When planting bonsai of Jasminum nudiflorum, several animal hooves should be put at the bottom of the pot as base fertilizer.
2. In the growth period of spring, the thin liquid fertilizer should be applied once or twice a month.
3. The period of flower bud differentiation is from July to August. Liquid fertilizer containing more phosphorus should be applied to facilitate the formation of flower bud.
4. For example, in the early flowering stage, the application of a rotten thin organic liquid fertilizer can make the flowers colorful and prolong the flowering period.
5. In spring, pruning should be done after flowering, and cake fertilizer or base fertilizer should be applied once, and manure should be applied every half month in growing season. Pay attention to the application of phosphorus and potassium fertilizer in the late growth stage, so as to promote more strong branches after pruning.
Watering points:
1. Jasmine likes to be moist, especially in hot summer. Besides watering once a day in the morning, it should also be watered properly in the afternoon. In order to maintain the humidity of small environment, water should be sprayed to the ground frequently. In the rainy season, the basin should be put down or moved to a place free from rain. In winter, the temperature is low and the water evaporation is little, so we should water less.
2. During the period from flowering to flowering, the spring Jasmine should be watered 1-3 times according to the degree of soil dryness and wetness. Before the rainy season, it should be watered frequently. In the growing season, it is not allowed to topdressing, and it should not be watered after the beginning of autumn, so as to prevent the branches from being too long and too tender to survive the winter safely.
Pruning tips: Jasminum has strong sprouting power. During the growth period, we should often pick the heart, cut off or shorten some branches, so as to maintain the tree shape. After the flower withers, the branch should be cut short, generally leaving only 2-3 buds. The main branch can leave more buds. After the new branch is born, if it is properly maintained, the flower buds will grow in clusters.
Basin soil replacement: every year, the branches of Jasminum nudiflorum should be cut short after flowering and fertilized in the basin to facilitate flowering again in the next year.
Breeding points:
1. Ramet method. Jasminum nudiflorum can be carried out in spring and autumn, but it is better to plant at the beginning of sprouting in spring. Each clump can be divided into 20 small clumps, so it is easy to survive.
2. Layering method. The hard branch is usually layed in March, and takes root in June. The tender branch is layed in May. It can take root 30 days after layering. If it is watered regularly, it will take root more quickly. When the Jasminum nudiflorum is layed, it does not need to be cut. It can stand at the base of the layering with a small stick and be tied with a rope to make it grow upward. It can be separated from the mother plant one year after pressing.
3. Cutting method. In February, after the flowering of Jasminum nudiflorum, cut 15 cm long branches and insert them into the soil. The part buried in the soil accounts for about half of the branches, and remove the leaves. The aboveground part has leaves or no leaves, but it is easy to take root with some leaves. After a month, it can take root.
Pest control:
1. Mosaic. Control methods: first of all, weeds should be removed in time to reduce the source of infection. Secondly, aphids should be controlled as soon as possible to eliminate virus vectors.
2. Brown spot. Control method: spray 70% chlorothalonil wettable powder 1000 times liquid and other fungicides at the early stage of the disease.
3. Gray mold. Control method: planting density should be reasonable. Pay attention to ventilation and reduce air humidity. The diseased leaves and plants should be removed in time to reduce the source of infection. In the early stage of the disease, spray 50% sukeling or 50% chlorhexidine WP 1500 times. It is better to apply it alternately with 500 times of 65% mebendazole WP in order to prevent drug resistance.
4. Spot disease. Control methods: breeding disease resistant varieties, strengthening the management of fertilizer and water, increasing the application of organic fertilizer and phosphorus and potassium fertilizer, avoiding partial application of nitrogen fertilizer. In the early stage of the disease, 70% thiophanate methyl 1000 times solution, 75% chlorothalonil wettable powder 1000 times solution or 1 ∶ 1 ∶ 100 Bordeaux solution were sprayed.
5. Leaf spot. Control methods: strengthen the cultivation management, cultivate disease-free seedlings, and disinfect the soil of seedbed; The greenhouse should be ventilated in time to reduce the air humidity. The residual body of the diseased plant should be removed in time. After the onset of the disease, 50% succinic acid copper wettable powder 500 times or 72% agricultural streptomycin wettable powder 4000 times were sprayed.

Experience of breeding Jasminum nudiflorum
1. When planting spring, a few pieces of animal hooves should be put at the bottom of the pot as base fertilizer. In the growth period of spring, the thin liquid fertilizer should be applied once or twice a month. The period of flower bud differentiation is from July to August. Liquid fertilizer containing more phosphorus should be applied to facilitate the formation of flower bud. For example, in the early flowering stage, the application of a rotten thin organic liquid fertilizer can make the flowers colorful and prolong the flowering period.
2. The newly planted or newly changed spring Jasmine should be watered first, placed in shade for about 10 days, and then placed in half shade and half sun; Maintain for a week, and then place it in a sunny, well ventilated and humid place for maintenance.
3. In winter, the South can survive safely as long as the pot is buried in the leeward and sunny soil. In the north, it should be moved to low temperature (about 5 ℃) indoor in early winter. If you want to bloom in early spring, you can timely move it into the sunny room with medium or high temperature. If you place it in the sunny room at about 13 ℃, spray water on the branches and leaves once or twice a day, and it will bloom in about 20 days; If placed at about 20 ℃ indoor sunny place, about 10 days can blossom.
4. After flowering, keeping the room temperature at about 8 ℃ and paying attention not to let the wind blow directly can prolong the flowering period. After flowering, the higher the room temperature, the faster the flowers wither.
