(1) the land selection, land preparation and seedling cultivation should choose cool, fat and wet raw wasteland or mature land, and the loose and fertile sandy loam soil should be better, and the cultivation land should be fallow land or second wasteland with deep soil layer. In the middle of July, shrubs and weeds were cut down, spread on the ground and burned, then the land was turned more than 25 centimeters deep and matured in the sun, and then, before planting, 37500 kg of rotten barnyard manure per hectare was applied and turned into the soil as base fertilizer.

On the planting ground where the rake is fine, the holes are staggered in a triangle according to the row spacing of 33 cm × 27 cm, with a depth of 20 cm. Then, the root neck of the seedling was 0.3 cm thick and 0.5 cm thick, and 3 seedlings were planted in each hole according to the zigzag arrangement of each hole. After the planting, the seedlings were pressed while covered with soil. When the soil was covered to half a hole, the seedlings were gently lifted up to stretch the root system. Then cover the soil to the full hole, apply an appropriate amount of plant ash or soil fertilizer, cover the fine soil not over the root neck of the seedling 2 cm.
