摘要
该文探讨了阴山北麓农牧交错区麦薯带状间作农田土壤的抗风蚀效果.研究表明,有88.46%～98.56%的翻耕带土壤风蚀物能够被保护性耕作带截留,是一种既可以保护间作翻耕带,又能满足地区种植结构要求的防风抗蚀的种植方式.在定量研究的基础上,提出了保护性耕作带截留风蚀物的标准留茬高度和植被覆盖度分别为30 cm和50%.
The authors investigated the effect of wind erosion resistance for wheat and potato strip intercropping farmland in agro-pastoral ectone in Yinshan Mountain areas. The results show that 88.46% -98.56% of the wind erosion matter can be intercepted by the conservation tillage strip. Strip intercropping can both protect strip ploughed land and satisfy the needs of this area＇s planting structure. It is a planting method to resist wind erosion. Based on the quantitative study, the authors put forward that the standard residual stubble height to intercept wind erosion matter in the conservation tillage strip for the wheat and potato intercropping farmland is about 30 cm, and the standard coverage percentage of vegetation is about 50%.
