摘　　要：保护性耕作技术是在能够保证种子发芽的前提下,通过少耕、免耕、化学除草等技术措施的应用,尽可能保持作物残茬覆盖地表,减少土壤水蚀、风蚀,实现农业可持续发展的一项农业耕作技术。通过保护性耕作与传统耕作的对比,分析了保护性耕作在减少水土流失方面的作用,提出了保护性耕作的适宜年降雨量为250~800 mm,温度不低于7℃的地区实行,并提出了玉米连作区（玉米-玉米-玉米）、玉米大豆轮作区（玉米-大豆-玉米）和大豆连作区（大豆-大豆-大豆）3种不同农业区的保护性耕作种植模式。Conservation tillage is an agricultural tillage techniques that under the premise of ensuring seed germination,through minimum tillage,no tillage,chemical weeding and other technical measures to keep crop residues,reduce soil erosion and wind erosion,and achieve sustainable development of agricultural.Based on the conservation tillage compared with conventional tillage,analysis of conservation tillage to reduce soil erosion was conducted,proposed that it adaptd to apply in area with rainfall was 250~800 mm and temperature was over 7℃,and provided conservation tillage cropping patterns of three different agricultural areas,which were：maize continuous cropping area,maize and soybean rotation area and soybean continuous cropping area.
