摘要
以邢麦7号为试材,探讨不同灌水次数对冬小麦耗水量、产量、农艺性状和水分利用率的影响。结果表明:不同处理下,冬小麦产量、耗水系数和水分利用率均不同,各处理间差异显著。随着灌水次数的增加,冬小麦产量也呈现增加的趋势,但是水分利用率随着灌水次数的增加逐渐减少。灌两水为最优组合(拔节水和扬花水),产量为8 187.3 kg/hm2,水分利用率21.4 kg/mm·hm2。
Xingmai No.7 was used as material to study the effect of different irrigation tina^s on the water consumption,yield,the agricultural traits and water use efficiency of winter wheat.The results indicated that water consumption coefficient, yield, and water use efficiency of winter wheat were remarkable difference. Along with the increase of times of irrigation, the yield increased, while water use efficiency of winter wheat was gradually decreased. Two-irrigation was the best treatment (jointing and flowering stages),the yiled was 8 187.3 kg/hm2, the water use efficiency was 21.4 kg/mm, hm2
