Leek cultivation techniques
First, select high-quality varieties of good selection, strong stress resistance, leaf hypertrophy, good quality of high-yield varieties, such as: Rhinoceras, Pododendron, ferret and so on. Second, sowing seedlings choose bright color, full of new seed sowing. Seed beds should be loose, fertile and well-drained sandy loam. Seeds soaked before sowing germination, until the buds grow and then sowing. Seeds of 300 to 400 grams per 66.7 square meters can grow 1 mu of Daejeon. When planting, sowing must be done. Cover the soil to a thickness of 1 to 1.5 centimeters. Water immediately after sowing to cover the mulch to facilitate warming and protection. After the emergence, remove the mulch. 3. Before transplanting and transplanting, 3,000 to 4,000 kg of organic fertilizer shall be applied to the field per mu before transplanting. The seedbed shall be irrigated with seedling water before planting, and then the seedling shall be dug up and shaken to remove dirt, and the tip of the fibrous root shall be cut off by 2-3 centimeters. Promote new root development. The leaves can be cut off to reduce the evaporation of leaf moisture. Planting specifications: the use of ditching planting, spacing 50 cm, cluster distance 17-20 cm, 4-5 seedlings per clump. Fourth, field management For the first year after planting, the leeks are not cut, but it is necessary to strengthen management and raise roots and strong seedlings. In the spring of the following year, the new leaves can be harvested when they grow 25-28 cm long. Before harvesting, they are drenched with water once. After the harvest, the new leaves are 4-5 centimeters long, watered and fertilized, and 400 kg of organic fertilizer is applied per acre. Simultaneously apply 15 kg of compound fertilizer to supplement nutrition and promote growth. The beginning of May with no flower and nourishing moss will not cut leeks, and it will be able to bloom and flower in June and July. From the second year onwards, leeks should be cultivated once a year in combination with cultivators to solve the problem of rooting leeks year by year. Fifth, timely prevention and control of pests and diseases: 1. Use adult armyworm traps to kill adults. 2. Use 80% dichlorvos EC 1000-2000 times or 50% phoxim EC 1000 times to control adult pupae. Leek Botrytis cinerea: At the time of onset, 50% Suo Ke Ling WP 1000 times solution or 50% Propionine WP 1200 times solution can be sprayed on the next day after the leek is harvested and sprayed 2-3 times. Leek disease: at the beginning of the disease, 64% anti-virus WP can be used 500 times or 72% Propmethrin 800 times. After the leeks are sprayed, they are sprayed and sprayed every 5 to 7 days. They are sprayed 2-3 times.
