The transplanting plant spacing is 6 cm and the row spacing is 5 cm. Then the planting depth is 5 cm, the planting row width is 1.2 meters, the length is about 5 meters, and the row gap is 20 cm, which is convenient for management. Planting should be shallow and sparse.

5. Disease and pest control
