摘  要:
通过测定设置沙柳沙障的沙丘土壤与对照地土壤有机质N、P、K含量和机械组成等理化指标,分析设置沙障对沙丘土壤理化性质的变化。结果表明:与对照相比,设有沙障的沙丘土壤表层细沙、粉沙含量分别提高71.0~106.8g!kg-1、2.92~14.03g!kg-1,沙丘土壤有机质、全N、全P、全K含量分别提高了1.7倍、2倍、1.51倍和1.03倍以上,说明设置沙障可增加沙丘土壤表层细小颗粒含量,有利于沙丘土壤的养分积累,促进土壤环境改善。

摘  要:
In this work,the effect of Salix psammophila checkerboard on physical and chemical characteristics of sandy soil were analyzed by comparing the sandy soil of S.psammophila checkerboard and control sand of which physical composition,organic matter,total nitrogen,total phosphorus,total potassium and pH were determined.Studied results indicated that compared with control sand,established S.psammophila checkerboard increased the contents of fine sand and clay sand of soil surface with 71.0~106.8g·kg-1 and 2.92~14.03g·kg-1,the contents of organic matter,total nitrogen,total phosphorus and total potassium enhanced with 1.7,1.2,1.51and 1.03times,respectively.It shows S.psammophilacheckerboard can increase fine particles content of sandy soil surface,improve nutrition accumulation and edatope.
