Leeks can survive without being exposed to light because the roots and stems store more organic matter, which enables it to consume its own nutrients in the process of growth, while the nutrients in the soil are also able to meet the requirements of its growth, so it can survive in the absence of light conditions.

A, general planting leek site can choose solarium, plastic greenhouse, large warehouse, spacious houses for shade.

Methods:

3, the soil selection: it is appropriate to choose the soil layer of deep, high organic matter content, loose and permeable, water retention and fertilizer, irrigation and drainage of sandy loam. Irrigation and drainage of sandy loam;

4, soil preparation for beds: before planting, be sure to turn the soil deep, in order to facilitate the development of the root system. It is good to plow the soil up to 25-30 centimeters deep and expose the soil to sunlight for 3-5 days after deep plowing to break up the large pieces of soil and make the beds with fine tilling;

5. Choose the suitable cultivation method: leeks can be sown and planted in spring and fall every year, and the time from mid-March to mid-April is better in spring. Autumn in late September to early October;
