摘要
[目的]研究保护性耕作对土壤含水量和风蚀量的影响。[方法]以位于内蒙古阴山北部武川县典型农牧交错带的耕地为试验地点,比较用不同保护性耕作对不同作物留茬的土壤含水量、风蚀量的影响。[结果]与传统耕作相比,马铃薯免耕、油菜留茬和燕麦留茬可以提高土壤含水量,极大地减少土壤风蚀。[结论]留茬耕作和免耕是当地农业发展和环境治理一条可持续的耕作途径。
[Objective] The purpose was to study the effect of conservation tillage on soil moisture and wind-blown mass. [Method] Several conservation tillage lands were used to compare the impact of soil moisture and wind-blown mass of different crop stubble in Wuchuan County of Inner Mongolia. [Result] Compared with conventional tillage,no-tillage potato,rape stubble and oat stubble could increase soil moisture and greatly reduce soil erosion. [Conclusion] Stubble tillage and no-tillage was a sustainable way of farming for local agricultural development and environmental governance.
