Third, soil preparation and fertilization

When the seedling grows to 2-3 true leaves, it can be poured. 1 time water. When pouring the second water, 15 kg of urea can be applied per acre with water, and the appropriate amount of vegetable stalks can be sprayed on the foliage to improve the ability of the seedlings to absorb water and absorb fertilizer.
Fifth, timely harvest
