摘  要：
以旱作玉米地为研究对象,对免耕与传统耕作的农田积沙量、地表不同高度间积沙曲线、表层1 cm 深土壤粒径组成等内容进行了重点观测分析。结果表明:免耕对减少旱作玉米农田就地起沙的贡献率是非常巨大的,间接反映出沙质旱耕农田是很主要的沙源地之一,而以免耕对农田就地起沙的防效特别突出,在干旱风沙区是一项很值得推广的农耕措施。

摘  要：
This thesis's analyses are based on the no- irrigation condition maize farmland. We did some experiments through zero and traditional tillage those are about the effect of sand collection quantity curve, the surface (1 cm) soil's diameter etc. in different high degrees from the land's surface. The results are : zero tillage method has a very deeply contribution for the reduction of wind erosion. It also can be reflected that traditional tillage farmland is one of the main sand source indirect. We can say zero tillage has a very deeply contribution for the reduction of wind erosion. So it is a very useful tillage system and is worth to popularize in the sand -dust storm lands.
