What are the management methods of summer leek? Please give guidance to the management of summer leek can refer to the following methods: cut-free: due to the summer temperature regulation nutrition tired less, high consumption, affecting plant growth, and leaf tissue fiber increase, rough texture, growth weakening and showing a phenomenon of rest. At this time, there is generally no more harvest. Otherwise, it will affect the autumn growth and yield, but also affect the life span of leek. Plant culture should be strengthened to lay a good foundation for autumn production. Weeding: high temperature and rainy summer, which is conducive to the growth of weeds and affects the growth of leeks. After each harvest, weeds are eliminated in time, and then 25% herbicide is sprayed on the ground between rows. Picking flower bolts: due to the real-time flowering and fruiting of leek, a large amount of nutrients are consumed, affecting plant growth, tillering and nutrient accumulation, thus affecting the yield in the coming year. Therefore, in addition to the seed field, the flower should be removed in time when the flower is young to facilitate plant culture. Strengthen fertilizer and water management: according to seedling situation, soil moisture and weather conditions, irrigate water once every 7-10 days, and apply human feces and urea fertilizer 3 times with water. Disease prevention and insect control: leek is most prone to Fusarium wilt in the case of high temperature in summer, especially after heavy rain, it is exposed to the hot sun again, close to the ground, occurs in hot spots, and the whole plant dies when it is serious. Therefore, attention should be paid to drainage and waterlogging prevention in summer. after heavy rain, shallow irrigation with well water should be used to reduce the ground temperature and remove the yellow leaves on the ground, so as to make the rows well ventilated and reduce the harm. It can also be irrigated with 50% carbendazim 500 times solution for root control. The occurrence of leek maggots is also very serious in summer. Generally, 90% trichlorfon plus 100g 200 grams of alkali surface or 50% phoxim 800 times solution is used to control leek maggots at the beginning of summer. At the end of summer, 3000 times of permethrin was used to spray leaves, dung piles, thatched pits and fields to eliminate pests.
