摘要: 以内蒙古自治区武川县上秃乡保护性耕作农田地表土壤为研究对象,利用移动式风蚀风洞对麦茬深松农田地表进行土壤抗风蚀效果测试研究。研究结果表明,麦茬深松农田地表相对传统耕作地表可降低近地表风蚀土壤量,对土壤输沙影响显著。该研究可为防治农田土壤风蚀提供理论依据.Abstract: Soil-erosion experiment was conducted on wheat stubble fields by a movable wind erosion tunnel on bald rural farmland conservation tillage in Wuchuan County, Inner Mongolia Autonomous Region. The results show that the surface of subsoiling wheat stubble fields can reduce soil erosion of near-surface volume compared with traditional farming. It also impacts on sediment transport of soil significantly. The provide a theoretical basis for control soil erosion.
