自然免耕技术在水土保持中的作用分析

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

自然免耕技术在理论和实践上都可以应用于任何土壤,但在水土保持中运用不是很广泛。通过对自然免耕的关键技术"小三化"(腐殖化、结构化、细菌化)、"大三化"(林网化、渠网化和复种化)和4个必须遵循的原则(连续垄作、连续浸润、连续植被和连续免耕)的介绍,从水土保持机制角度,有针对性的分析自然免耕技术在水土保持中的作用。

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.
