不同灌水处理对冬小麦籽粒灌浆过程的影响研究

Effect of Different Irrigation Treatments on Grain Filling Process of Winter Wheat

利用2004-2005年度冬小麦测坑与桶栽籽粒灌浆试验资料，研究了冬小麦不同生育期灌水和灌浆期不同灌水处理对冬小麦籽粒灌浆进程的影响。在试验结果分析的基础上，提出了冬小麦生育期适宜灌水制度和灌浆期适宜灌水时间与土壤水分控制指标，这对干旱缺水的华北地区实现冬小麦节水与高产的统一有着重要意义。

Through using experimental data of grain filling of winter wheat planted in lysimeters and pots in 2004~2005, the effect of irrigation treatments at different growth stages as well as at grain filling stage on the grain filling process of winter wheat were studied. Based on the analysis of the experimental results, the optimal irrigation scheduling and optimal soil water index at the grain fillmg stage were put lorward. It was significant to realize the unification of water-saving and high yields of winter wheat in the droughty North China Plain.
