Sowing and seedling raising: Sowing and seedling raising are mostly carried out between February and March, and germination and disinfection are required before sowing.The seeds can be soaked in warm water for about two days, and then sowed when the seeds are white, so that the germination rate will be higher.Pay attention to covering a thin layer of soil on the upper layer of soil after sowing, and treat it with heat preservation and moisture preservation.

2. Root burying and seedling raising: After defoliation and before germination, roots should be collected every year. Lateral roots with a thickness of 2 to 3 centimeters should be selected from large trees with relatively strong growth, and the length should be controlled at 15 to 20 centimeters. After shearing, they should be aired for 2 to 3 days, and then they can be directly buried or obliquely buried.

3. Cuttage seedling raising: In addition to the above two methods, cuttage seedling raising can also be used.The specific method is to cut annual strong branches as cuttings, the length of which is controlled at about 20 centimeters.After treatment, it can be directly inserted into the matrix, and the survival rate is relatively high.
