The transplanting of mulch corn should master the principle of “first filming and then transplantingâ€. Generally, the mulch is laid one week before transplanting to increase the temperature and moisturize. Suitable for transplanting, the seedling age is from three leaves to one heart and four leaves. It is transplanted by wide and narrow row technique. The wide row spacing is 70-80 cm, the narrow row spacing is 35-40 cm, the plant spacing is 27 cm, and each row is transplanted 4 rows. When transplanting, the size of the seedlings should be graded and transplanted. First, lay the seedlings according to the plant spacing, then gently put the nursery to prevent the roots and the seedlings. When placing the nursery, pay attention to the fact that the blade is perpendicular to the surface of the clam, that is, the blade of the east and the west is placed north and south, and the blade of the north and south taro is placed. After planting, the soil and the bottom of the carcass are tightly sealed with soil, and then the soil moisture is poured into the living water.
