The cutting place can be selected at the edge of the forest or in the glade with good microclimate. The cutting seedbed can be built into a bed frame with a height of 60 cm in the east, 40 cm in the west and a width of 365,438+05 m in the east and west (the length depends on the terrain). A dark tunnel with a depth of 40 cm and a width of 40 cm is opened in the center of the bed to communicate with the outside of the seedbed, and the ditch is filled with gravel until it is turtle-backed.

The inserted soil is red soil alluvial soil with a thickness of 20-25cm. Disinfect with 0.2% potassium permanganate one week before cutting and cover with film. A 2-meter-high fixed shade shed is set up on the bed, and the light transmittance is about 30% ~ 40%. In order to facilitate transplanting, you can also use nutrition pots for cutting.
