Fertilizing Generally, 50 kg of low-nitrogen, high-phosphorus, high-potassium sulfur-based compound fertilizer and 5000 kg of decomposed farmyard manure are applied. After the fertilizer is evenly spread, the tillage is carried out, and the soil is ploughed and made into a crucible of 100-120 cm wide. Choose strong seedlings Before transplanting, it is recommended that the onion age is 50-55 days. At this time, the seedlings tend to root, and the growth is quick after transplanting. The diameter of the seedlings is 5-6 mm, and the seedling height is about 25 cm. 10 to 15 days before transplanting, spraying the potassium dihydrogen phosphate foliar fertilizer on the seedlings can promote the early rooting of the seedlings after colonization and enhance the cold resistance of the seedlings. It is usually planted in early or mid-November, and the membrane is raised to increase the ground temperature 5 days before transplanting. Plastic film cultivation can enhance the cold resistance of onions to winter, improve soil water retention and fertilizer retention capacity, and greatly increase onion yield. Before the film is covered, it is necessary to fill the water to make the sputum. After the water in the sputum is completely oozing, when the soil is wet, spray 33% of the weeding solution to 100 ml per acre, spray evenly on the surface of the sputum, and then cover the membrane. When working, choose a windless weather, and use the soil pressure on both sides of the membrane. Holes were punched in the mulch before transplanting, with a line spacing of 18 cm and a plant spacing of 15 cm. Immediately after transplanting, the transplant should be carried out. When transplanting, the root should not be exposed on the surface, but it should not be too deep. The planting depth should be 2 to 3 cm.
