Select the Gaoshuang plot that did not grow cruciferous crops in the previous crop, and make a 2-meter-wide bed after deep ploughing and fine rake to open a deep ditch. The basic application of organic fertilizer is 2000kg / mu and compound fertilizer is 50kg / mu. The seedling age was 30 min 35 days, and the seedlings were planted after 4 p. M. in cloudy or sunny days, and the planting density was determined according to the varieties. The flat-head varieties were planted with 2800 plants per mu. Watering live trees after planting.
