花椒是经济价值较高的树种,而且根系发达,耐干旱瘠薄,保土作用强,具有较高的培育价值。花椒的繁殖当前多采用种子育苗,这一方法繁殖的后代分化比较明显,不易保持母树的优良品质。有的采用嫁接繁殖,但砧穗对后代遗传的影响不确定,现在国外也已开始由嫁接法转向扦插技术的探讨。 Zanthoxylum bungeanum is a tree species with higher economic value, and has well-developed root system, drought-resistant infertility, strong soil-protecting effect and high cultivating value. Prickly ash seed multiply the current use of seedling breeding, offspring of this method of breeding more obvious differentiation, not easy to maintain the excellent quality of the mother tree. Some use of grafting, but the impact of anvil on the offspring of genetic uncertainty, and now abroad has also begun to shift from the grafting method of cutting technology.
