| 摘 要： | 不同时期灌水对冬小麦的产量有显著影响，适时适量灌水对提高冬小麦的产量具有重要意义，实验结果表明冬小麦冬灌应在11月底到12月份较适宜，春灌应在2月下旬到3月上旬较适宜。灌水量冬灌应控制在750～900m3／hm2，春灌600～750m3／hm2。灌溉定额应控制在1350～1650m3／hm2。

| Abstract: | To irrigate the winter wheat in different periods has an obvious effect on yield, therefore a timely irrigation with ap- propriate amount can increase the yield of winter wheat. The experiment result shows that winter irrigation should be carried out at the end of November to December; spring irrigation should be suitable in late February to early March. Irrigation amount in winter should be controlled at 750 ~ 900 m3/hm2 , spring irrigation at 600 ~ 750 m3/hm2 , irrigation quota should be con- trolled at 1 350~1 650 m3/hm2. |
