After beginning of autumn, before the leek grows rapidly, it is suggested that the grower must topdress once, with 300-500 kilograms of decomposed bean cakes per mu. When we topdressing, we can use bamboo poles to turn the leeks from the middle of two rows of leeks to both sides to expose the ground, then open a small ditch, sprinkle bean cakes in the ditch, and then cover the soil and water them once after fertilization. After that, water it every 5-7 days 1 time and continuously for 4-5 times. In late September, combined with watering, 20 kilograms of urea was applied to each mu of land, and watering and fertilization were stopped in early October.

Therefore, it is necessary to support on both sides of the leek border and pull iron wires in the border to prevent the leek from lodging, which is beneficial to ventilation and light transmission in the field, maintain the vigorous photosynthesis of the leek, promote the growth of the leek and reduce the occurrence of pests and diseases.
