1, seed selection: seed selection is the basic requirement for how to grow leeks. It is best to choose fine varieties such as chive 1 or Xue Jie No.4, wash their seeds, soak them in water at 53℃ to accelerate germination to improve germination rate, and then soak them in diluted carbendazim solution for 30 minutes to play a bactericidal role.

2. Soil treatment: Before planting leeks, the soil needs deep ploughing. Fermentation preparation is generally carried out in late April. Appropriate amount of organic fertilizer should be added, and mixed and stirred after watering. After ploughing, it is necessary to level the soil, apply less base fertilizer when preparing the soil, and add appropriate amount of calcium superphosphate to promote root growth.

3. Planting and field planting: bury the turmeric seedlings in the soil, plant them reasonably and closely, keep the spacing between each plant at about 10 cm, immediately cover with a layer of plastic film or straw after planting, cultivate the soil for the first time when the seedlings are 50 cm high, cut off the upper leeks, and then cultivate the soil for the second time, and apply a small amount of compound fertilizer and manure before cultivating the soil.

4. Planting management; When planting leek, it should be avoided in the season of high temperature and high humidity. During the growing period, plants should avoid light as much as possible. Young seedlings can be properly treated with thinning, and leeks should be shaded from light. Fertilization is mainly based on organic fertilizer solution, and fertilizer and water can be increased when the weather is dry.
