干旱是旱地农业可持续发展的主要限制因素，如何在水资源有限的条件下提高降水利用率，已成为旱作农业研究的主要内容。覆盖耕作是干旱、半干旱和半湿润干旱区对土壤进行保护性管理的有效手段，通过采取少耕、免耕，深松，辅之以覆盖措施，实现对旱地土壤环境因子水、肥、气、热的调控，从而达到土壤环境质量的可持续发展和良性循环，实现农作物高产、稳产的目的。

Drought is a major limiting factor in the sustainable development of dryland agriculture, how to improve the utilization of precipitation in the conditions of limited water resources, has become the main content of dry farming research. Covering farming in arid, semi-arid and sub-humid arid area of soil management is an effective means of protection carried out by taking minimum tillage, no-tillage, subsoiling, complemented by covering measures to achieve environmental factors on upland soil water, fertilizer, gas thermal regulation, so as to achieve sustainable development of soil environmental quality and a virtuous cycle, to achieve crop high yield purposes.
