Jasmine is a traditional fragrant flower. In many places, Lai Li is cultivated in open fields and the flowering period is as long as 5 to 7 months. The main techniques of jasmine field management are as follows: - Weeding and weeding. Weeding and weeding should be carried out frequently to create a loosely ventilated soil environment for Lilly root system to avoid nutrient dispersion and promote its growth and development. In general, the annual cultivating and weeding will be 6-8 times. Second, reasonable control of water. The flowering leaves of Lai Li are luxuriant. The transpiration of the water is large. The soil should be kept moist. The water content in the field during the flowering period should be kept between 60% and 80%. In the morning and evening in summer, in the morning in autumn, and in the winter at 4-5 days every day. Pour 1 water. Early hot weather can be sprayed with a sprayer to moisten its leaves, which is conducive to lush growth. Third, scientific fertilization. When the jasmine shoots germinate, the concentration of 50% thin human fecal urine is 1500 kg per acre. Add 4 kg of urea. In the summer after pruning, combined with cultivating and weeding, apply 500-1000 kg of fertilizer per acre, 15-20 kg of urea, 35-50 kg of superphosphate, and 25 kg of compound fertilizer. Buds use 50 grams of potassium dihydrogen phosphate per acre, 150 grams of urea water distribution 40 kilograms, foliar spray fertilizer. At the end of autumn flowers, it is usually 10-15 days to apply 1 fertilizer. After the white dew, the flowering period has basically ended and fertilization can be stopped. In the usual fertilization to deepen the ditch, should not be applied, if a small amount of bone powder applied, can increase the fragrance. Fourth, pruning. After Lai Miao is transplanted, it is necessary to carry out sparse leaves and cultivate high-yield trees. Pruning must end before the jasmine sprouts. For the old jasmine plants that have been grown for more than 6 years, the first buds will appear after the beginning of summer and before the small age. The number of buds is small, and the flowers are small and of poor quality. To prevent consuming nutrients, more shoots are promoted. Students should cut off the buds and buds on their branches. This is a key measure to ensure that jasmine blossoms and blossoms. After entering the flowering period, a short cut is required after each inflorescence is picked. In each of the 6th, 7th, and 8th months of the harvest, 2 pairs of leaves were trimmed. Fifth, pest control. The main diseases of jasmine are caused by fungi-induced white feathers and dead branches. It was found that the diseased plants should be treated, and the diseased plants should be removed or pentachloronitrobenzene must be applied. Or use 40% sclerotia net or 25% scouring, or 40% pentachlorone and stupid 500-800 times liquid to root or spurt control. Insect pests are mainly harmed by scale insects, red spider mites, and pupa horseshoe bugs (Lyly scapes) and can be sprayed with 40% dimethoate emulsion 1500-2000 times. 7-10 days after the re-spray 1 times. Spray time should be after the end of the afternoon flower collection. In addition, when the pests occur, they can smoke in the garden at dusk, which drives the adults to lay eggs.
