摘要
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 。
As the only evergreen broadleaf species in sand area of China, Ammopiptanthus is endangered. Based on the analysis of drought resistant, fairly salinization resistant, erosion tolerant and other capabilities, we found Ammopiptanthus is belong to better species with strong resistant capability. Due to the special characteristics of the seed and its special requirement of water at the beginning of growing, the natural growing ability is not strong. If some measures can be taken during planting, Ammopiptanthus can be used not only for fixing-sand, but also other aspects.
