It is an excellent native shrub species for the control of rocky desertification,as well as the preferred tree species for the ecological control of mountainous areas with severe and extremely severe rocky desertification and shallow soil. It has wide prospects in the follow-up development of the controlled rock desertification regions. The afforestation technology of planting bimonthly seedlings in small ponds has low cost and good effect,so S. davidii is an ideal tree species to replace Dodonaea viscosa in afforestation.展开更多
