风蚀是农业生态环境恶化的主要成因之一,用作物秸秆残茬覆盖地表是保护性耕作的重要内容,它可以减少风蚀、水蚀,抑制扬沙,进而提高土壤肥力和抗旱能力。研究农田各种残茬秸秆覆盖方式的抗风蚀效能对于实施保护性耕作具有指导作用。1内蒙古自然条件与留茬覆盖内蒙古位于北纬37°
Wind erosion is one of the main causes of agroecological environment deterioration. Covering the surface with stubble of crop stalks is an important part of conservation tillage. Wind erosion can reduce wind erosion, water erosion and sand suppression, thereby improving soil fertility and drought resistance. It is instructive to study the wind erosion resistance of various stubble mulching methods in farmland for conservation tillage. 1 Inner Mongolia Natural Conditions and Stubble Coverage Inner Mongolia is located at 37 ° N
