我国保护性耕作的研究进展

Research Progress of Conservation Tillage in China

保护性耕作是通过少耕、免耕以及地表覆盖秸秆等措施,减少农田水土流失,保护农田生态环境,获得生态、经济和社会效益协调发展的环境友好型耕作模式。为减少土壤侵蚀、荒漠化以及盐碱化等导致的耕地退化,土壤管理方式需要由传统的耕作转向保护性耕作,以保护土壤环境、稳粮增收。介绍了保护性耕作对农业可持续发展的重要性,系统阐述了保护性耕作的发展现状,分析了未来保护性耕作的发展重点与难点,并对保护性耕作未来的发展方向进行展望,为健全保护性耕作发展体系提供参考。

Conservation tillage is an environmentally friendly farming model that reduces soil erosion,protects the ecological environment of farmland,and achieves coordinated development of ecological,economic and social benefits by means of less tillage,no-tillage and surface mulching of straw.In order to reduce soil erosion,desertification and salinization,soil management methods need to be changed from traditional tillage to protect the soil environment,stabilize food and increase income.This paper introduces the importance of conservation tillage for the sustainable development of agriculture,systematically describes the current development status of conservation tillage,analyzes the key points and difficulties of future development of conservation tillage,and provides an outlook on the future development direction of conservation tillage to provide reference for improving the development system of conservation tillage.
