中文摘要试验设20cm留茬压倒(NPS20),40cm留茬压倒(NPS40),40cm立秆(NS40).20cm立秆(NS20),6750kg/hm~2覆盖(NSB40),3750kg/hm~2覆盖(NSB20)和传统耕作(CT)7个处理,在节水1950m~3/hm~2的条件下,研究了不同的秸秆覆盖量、留茬高度和秸秆处理对小麦产量、水分利用效率(WUE)和不同时期土壤水分的影响。结果表明。留茬覆盖免耕保护性耕作提高了春小麦的产量,NPS20,NPS40,NS40,NS20,NSB40和NSB20较CT分别增产53.08%,46.59%,40.81%,19.93%。17.33%和4.34%;留茬覆盖免耕保护性耕作提高了春小麦的水分利用效率(WUE)(NPS20,NS40。NPS40,NS20.NSB40,NSB20分别较CT提高58.02%,43.40%,47.27%,23.78%,20.69%,8.56%),但增加了小麦生育期土壤水分支出;不同处理在不同时期对土壤水分的影响不同。
英文摘要The influences of different qualities of mulched straw, height of standing straw, and straw treating style on grain yield, water use efficiency (WUE) and soil water content of different growth stages were studied in a field experiment aimed at saving 1 950 m~3/hm~2 water in the Hexi corridor. Grain yields were improved by conservation tillage with straw cover or straw standing, and that of NPS20, NPS40, NS40, NS20, NSB40 and NSB20 were increased by 53.08 %, 46.59%, 40.81 %, 19.93 %, 17.33 % and 4.34 % respectively compared with the CT. WUE and soil water consumption during spring wheat growth were also increased by conservation treatments, and WUE of NPS20, NS40, NPS40, NS20, NSB40, NSB20 were increased by 58.02%, 43.40%, 47.27% ,23.78% ,20.69% ,8.56% respectively compared with the CT. The influences of different treatments on soil water content of different stages were different.
