一、应变耕作有助于防止风蚀若刮风吹走了田间土壤,就得采取措施予以防治.明尼苏达大学自然资源保护学家Clif Halsey说:“应变耕作在春耕前能暂时减少风蚀危害”.应变耕作使裸露地面粗糙,并且己证明对壤土和粘壤上是有益的.Halsey建议耕作土壤要在地面留有较大的土块及明显成垄.用凿形犁或用带有2—3圆盘的单向圆盘犁每隔一定距离成垄,就能做到这一点.
First, strain farming helps prevent wind erosion If the wind blows away the field soil, you have to take measures to prevent and cure.University of Minnesota natural resources protectionist Clif Halsey said: “Strain farming in the spring before the temporary reduction of wind damage.” Strain Tillage makes the bare ground rough and has proved beneficial to loamy and clayy soils.Halsey recommends tilling the soil to leave larger blocks and clear ridges on the ground.Use chisel plows or with 2-3 rounds One-way disc plow into the ridge at regular intervals, you can do this.
