中文摘要	通过在陇中黄土高原半干旱区的坡耕地上建立天然降雨径流小区,于2007年对粮草豆隔带种植保护性耕作防治水土流失效应进行定位研究.试验设传统耕作下春小麦与苜蓿间作(T_(WL))、马铃薯与苜蓿间作(T_(PL))、鹰嘴豆与苜蓿间作(T_(CL))和免耕秸秆覆盖下春小麦与苜蓿间作(NTS_(WL))、马铃薯与苜蓿间作(NTS_(PL))、鹰嘴豆与苜蓿间作(NTS_(CL))6个处理.结果表明:(1)免耕秸秆覆盖可显著减少径流量和侵蚀量,6个处理的水土流失量为T_(WL)＞NTS_(WL)＞T_(CL)＞NTS_(CL)＞T_(PL)＞NTS_(PL).(2)流失泥沙的养分含量中有机质、速效N、速效P、速效K的流失总量最大,全N和全P的流失总量最小.免耕秸秆覆盖对减少速效N、速效K和全P的流失具有明显的作用.(3)径流量、泥沙量与降雨量的回归关系均十分显著.保护性耕作是控制水土流失的有效措施.
英文摘要	The effect of conservation tillage of strip intercropping of grain-grass-legume on reducing soil and water losses was conducted with runoff-plots in sloping fields in the semi-arid areas of west Loess Plateau in Gansu province from 2007.Six treatments including conventional tillage of Spring Wheat/ Lucerne intercropping(T_(WL)),Potato/ Lucerne intercropping(T_(PL)) and Cheick Pea/ Lucerne intercropping(T_(CL)),no-tillage with stubble retention of Spring Wheat/ Lucerne intercropping(NTS_(WL)),Potato/ Lucerne intercropping(NTS_(PL)) and Cheick Pea/ Lucerne intercropping(NTS_(CL)).The results showed that:(1) No-tillage with stubble retention has significant effection to prevent soil erosion,the total amounts of runoff and soil loss of six treatments were T_(WL)>NTS_(WL)>T_(CL)>NTS_(CL)>T_(PL)>NTS_(PL).(2) The total loss of organic matter,available N,available P,available K in the nutrients of sediment loss is maximum,but the total loss of whole N and whole P is minimum,and no-tillage with stubble retention has obvious function to reduce the loss of available N,available K and whole P.(3) The regression relation among runoff,sediment yield and rainfall are very notable.It was indicated that conservation tillage could control soil and water losses significantly.
