The seedbed is 1.5 meters wide and 6 meters long, with an interval of 8 centimeters and a depth of 5 centimeters, covering soil and watering, keeping 20 degrees during the day and 12 degrees at night. The seedlings grew to 4 true leaf pine seedlings in the soil. Apply light fertilizer and water, grow 6 leaves and plant in the field.

When planting, high ridge planting, generally 10 cm high, 30 cm wide ridge row, 20 cm apart ditch. The distance between the planting plants is 20 cm, and the length of the ridge row is determined by the topography, which can be disconnected from the middle and open the ditch horizontally. About 2000 jin of fertilizer is applied per mu and 3000 plants are planted. The planting depth is under the help, and the temperature should be above 14 degrees at night after planting.
