1. Before sowing, weed the land, loosen the soil and apply an appropriate amount of base fertilizer. Sow leek seeds in loose soil, water them properly and soak the soil to provide enough water for the seeds. During curing, the ambient temperature should be kept at 15 ~ 20 degrees, and the moisture should be controlled. After 7 ~ 15 days, leeks can germinate.

2. After the leek germinates, it can be given enough light and water, which can promote the growth of new buds and leaves of leek. During the curing period, water properly to keep the soil moist as much as possible. After the leaves of leek grow out in the later stage, we can apply appropriate fertilizer to it, and the fertilizer is mainly nitrogen fertilizer, which can promote the growth of leek stems and leaves.

3. During the later growth of leek, thin fertilizer should be applied frequently, and most of the fertilizers are mainly phosphorus and potassium fertilizers. During baking, 10 ~ 15 days, leek can be applied with 1 times thin fertilizer to promote the growth of stems and leaves and enhance the stress resistance of leek. During curing, 1 bactericide can be sprayed for about 20 days to prevent leeks from being damaged by pests and diseases.
