1, sowing seedlings: sowing seedlings is mostly carried out between February and March, before sowing to catalyze the germination disinfection. Seeds can be placed in warm water for soaking, about two days, when the seeds are white before sowing, so that the germination rate will be higher. Note that after sowing the seeds should be covered with a thin layer of soil on the upper layer of soil, insulation and moisture treatment.

2, burying the roots of seedlings: every year after the fall of the leaves to the germination of the root, from the growth of more robust trees in the selection of two or three centimeters thick lateral roots, the length of control in the 15-20 centimeters, after cutting and drying for two or three days, and then buried straight or buried diagonally can be.

3, cuttings seedling: In addition to the above two methods, can also be used to cuttings seedling method. The specific method is to cut the annual robust branch to do the plug, the length control in about 20 centimeters. After treatment, directly inserted into the substrate on it, the survival rate is also relatively high.
