NTS improved the rotation grain yield significantly while no-till without stubble retention had the worst grain yield compare to conventional tillage system.The average yield of spring wheat under NTS was 18.10%,26.21%,13.15%,2.34%and 2.38%higher than that under T,NT,TS,TP and NTP respectively.The average yield of field pea under NTS was 20.25%,30.33%,15.83%,8.82%and 10.39%higher than that under T,NT,TS, TP and NTP respectively.

这归功于NTS处理改善了土壤结构性和渗透性能，并提高了土壤水分和肥力状况，最终体现为作物产量显著提高。6年间NT处理平均纯收益为1692.44￥/ha，比T、TS、NTS、TP、NTP增加了37.52%、194.58%、9.02%、86.79%、13.99%；平均产投比为2.98，比T、TS、NTS、TP、NTP提高了0.61倍、1.28倍、0.52倍、1.10倍、0.52倍。
