Function of natural no-tillage technology in soil and water conservation

Though natural no-tillage technology has wide uses for every kind of soil both in theory and proactice,it has not used for soil and water conservation work.The paper introduces six key technologies,such as soil with humus,structure and bacteria,protection belt,irrigation work and sequential cropping,and four principles like successive rotation,soakage,planting and no-tillage for the implementation of the natural no-tillage technology,and analyzes the roles of the natural no-tillage technology for soil and water conservation.
