| 摘 要： | 为研究微喷灌模式下不同灌水量对冬小麦生长、产量及水分利用效率的影响,于2015年10月开展了大田试验。以"小偃22号"为供试品种,研究高水W3(拔节期和开花期各灌水60 mm)、中水W2(拔节期和开花期各灌水40 mm)、低水W1(拔节期和开花期各灌水20 mm)和全生育期不灌水W0 4个处理下冬小麦的生长、产量及水分利用效率。结果表明:随着灌水量的增加,各处理的生长指标呈上升趋势,处理W1、W2、W3的籽粒产量分别较处理W0增产17.75%、35.78%和36.72%,但W2和W3处理间无显著差异;处理W2的水分利用效率和收获指数最高,较处理W3提高了0.22 kg·m~(-3)和0.01。综合对比冬小麦生长、产量和水分利用效率,得出拔节期和开花期各灌水40 mm为冬小麦最优灌水量。
