2、0(土壤相对含水量:播种期80%+拔节期65%+开花期65%)、W2(土壤相对含水量:播种期80%+拔节期80%+开花期80%)和W3(土壤相对含水量:播种期90%+拔节期80%+开花期80%)处理,W1和W4处理间无显著差异;W1处理增加了0~200cm土层土壤贮水消耗量,降低了小麦拔节至开花期的耗水模系数,提高了开花至成熟期的耗水模系数;W4处理在开花至成熟期、拔节至开花期的耗水量和耗水模系数均较大.调亏灌溉条件下,W0处理水分利用效率较高,但产量最低;随灌溉量增加,其他处理水分利用效率为先增加后降低的趋势.耗水量
3、最高的W1和W4处理产量也最高,W1处理灌溉水利用效率和灌溉效益均高于W4处理,为本试验条件下高产节水的最佳处理.关键词冬小麦调亏灌溉耗水特性水分利用效率Effectsofregulateddeficitirrigationonwaterconsumptioncharacteristicsandwateruseefficiencyofwinterwheat.作者姓名英文(作者地址英文)Abstract:Fieldexperimentwasconductedtoexaminetheeffectsofregulatedde
