Greenhouse leek management technology

Greenhouse leeks are generally grown in spring and buckled in winter. Generally, plastic shed film is added in the middle and late November to the beginning of December. If the leeks are listed during the New Year's Day, the second 茬 can be listed in the Spring Festival. Before the shed, pay attention to the amaranth rooting and promote its germination. Especially in October, increase the water and fertilizer management of leeks, apply 667 square meters of compound fertilizer 50 kg, and simultaneously apply trichlorfon or phoxim. The pesticide is used to control the leek mantle, and the dosage is 1-1.5 kg. After the film is shackled, pay attention to controlling the humidity in the greenhouse. The humidity in the early stage is 70%, and the temperature in the later stage is 50%-60%. Pay attention to prevent the occurrence of gray mold and disease of the leek, and spray the gray mold and the metallurgical solution 2000 times on average for 10 days. Can play a preventive role.
