摘　　要：沙冬青是我国重要的珍稀濒危树种,苗木移栽后的成活率很低。从截根可行性、截根时间、截根深度等方面,对蒙古沙冬青截根技术进行了试验,得出了不同截根方式、截根时间、截根深度对幼苗成活、地上生长和根系生长的影响,初步解决了沙冬青移栽成活困难的关键技术问题。Ammopiptanthus is a significant rare and endangered tree species in China. Its breeding is very difficult in common ways. The experimentation was conducted in the aspects of feasibility analysis, method, time and depth of cutting roots for young Ammopiptanthus mongolicus seedlings in this article. The results showed that the methods, the time and the depth of cutting roots had a great influence on the rate of survive, the growth of ground and roots and the crucial technology of Ammopiptanthus in planting were found.
