沙冬青是我国西北荒漠地区唯一的超旱生常绿阔叶灌木树种 ,现渐近濒危状态。文中从其抗旱、耐盐、耐风蚀等抗逆性方面进行了细致的分析 ,发现沙冬青是抗逆性比较强的优良树种。但由于其果实的特殊性和种子发芽所需土壤有特定水分的要求 ,自然繁殖能力较差。如果在栽培过程中采取适当的措施 ,沙冬青不仅可作优良的固沙树种 ,而且在其他方面也有广阔的应用前景 Ammopiptanthus is the only super-arid evergreen broad-leaved shrub species in the desert region of northwest China, and is now asymptotically endangered. In this paper, we analyzed the drought resistance, salt tolerance and wind erosion resistance, and found that A. sativa is a good tree species with strong resistance. However, due to the particularity of its fruits and the requirement of germinating the soil for specific water, the natural reproduction ability is poor. If you take appropriate measures in the cultivation process, sand Dongqing not only for good sand fixation species, but also in other areas have broad application prospects
