Effect of wind erosion resistance of soil for wheat and potato strip intercropping farmland

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%.
