Do you know what jasmine seed planting methods are? What are the effects and effects of scented tea? What are the prospects?

First, jasmine seed planting methods and pest control

1. Sowing: in the north, seedlings can be raised in a greenhouse or geothermal seedbed, the seeds can be removed from the seedbed, the ground temperature is controlled at about 20 ℃, and the ground temperature is stopped after emergence. The sowing amount is about 300 grams per square meter of seedbed. When there is a pair of true leaves, the seedlings are transferred once, and a single plant becomes a seedling. 5-7 days before planting, cool down and release the strong wind to refine the seedlings, and plant after the final frost. Can also be on demand in the small arch shed, do not transplant, a seedling, according to 7 cm x 7 cm interval on demand.

2. Soil: if you want jasmine to grow well, it is recommended that the family potted jasmine soil should choose fertile sandy and semi-sandy soil. When planted in the slightly acidic soil with pH 6 to 6.5, the root system is dense and the growth is vigorous, such as heavy clay, lack of matrix, low fertility, poor ventilation, less root system, short plant, slender stems and leaves, and few flowers.

3. Watering: Jasmine is not resistant to drought, but avoid stagnant water. In rainy season, it is necessary to dump stagnant water in the basin in time, otherwise the leaves are easy to turn yellow. In summer, hot and sunny days should be watered twice a day, once in the morning and evening, if the leaves are found to curl and droop should be sprayed on the leaves to promote growth, the rainy season should often loosen the soil, so that there is no water in the basin. Water is watered every few days in spring and autumn. Winter should keep the basin soil moist, too much watering, the roots will be black and rotten, leaves withered and yellow, shedding.

4. Lighting: Jasmine is fond of hot, humid, ventilated and breathable environment, requiring sufficient light. Jasmine is afraid of the cold. Potted jasmine in the south can be cultivated outdoors to survive the winter. In the north, it is necessary to keep warm in autumn and winter, and move indoors and put it toward the south. If the light is strong, the branches are strong, the leaves are dark green, the flowers are many and fragrant, and if the sun is not enough, the flowers are sparse and not fragrant. The stronger the light is, the more developed the root system of jasmine is, the stronger the plant growth is, and the stronger the stress resistance is.

5. Temperature: Jasmine is sensitive to temperature, which requires warm, hot and humid climate and can adapt to higher air temperature, but it is not resistant to low temperature and poor cold resistance. When the temperature is below 10 ℃, jasmine grows very slowly, even stops growing. The buds can sprout at about 19 ℃, the buds can only be conceived at more than 25 ℃, and the buds can form and develop well at 30-40 ℃. If the room temperature is controlled at about 20 ℃ in the air-conditioned room, the opening time of the bud can be delayed by about 10 hours. after removing the low temperature, the room temperature will rise to the suitable temperature for the bud to open, and the jasmine can bloom quickly and the fragrance is pure.

6. Fertilization: the high temperature season in midsummer is the peak period for jasmine growth. More organic fertilizer and phosphorus and potassium fertilizer, such as peanut cake powder, bone powder, calcium superphosphate and multi-element flower fertilizer, are applied twice a month. Jasmine often has luxuriant branches and leaves but does not blossom in summer, the main reason is that too much nitrogen fertilizer is applied, resulting in the growth of branches and leaves. In such a situation, it is necessary to control fertilizer and water, increase the application of phosphorus and potassium fertilizer, and promote the gestation of flower buds. At the same time, we should pay attention to move the jasmine to a place with sufficient sunshine and good ventilation.

7. Prevention and control of diseases and insect pests: Jasmine is often harmed by borer larvae and shell insects and red spiders, which is most serious from July to September. It often eats buds and can be sprayed with almighty powder or permethrin plus water 200 times every semimonthly, that is, no diseases and insect pests should be sprayed, so that it is appropriate to spray at 9 am and 4 pm on a sunny day, and it is not suitable to spray in the hot sun at noon to prevent drug damage.
