以河北省5个小麦推广品种为试验材料，分别在0水（只浇底墒水）、1水（拔节后期浇水）、2水（拔节后期、提穗期各浇水1次）和3水（拔节后期、抽穗期、浇浆期各浇水1次）条件下，研究了花后去叶〔不去叶（ CK）、只保留旗叶、去掉所有叶片〕对小麦千粒重的影响。结果表明：不同去叶处理的小麦千粒重均极显著＜不去叶处理；0水处理下小麦千粒重最大，2水处理下小麦千粒重下降率最高。在小麦后期管理中，保持较大光合面积的同时，要适当进行灌水，以提高小麦的千粒重。

Five wheat cultivars in Hebei Province were used to study the effect of removing leaves after flowering ( no defoliation, keep the flag leaves, removing all leaves) on 1000-grain weight of wheat under the conditions of no irrigation ( watering before sowing ) , irrigate one time ( watering at late jointing stage ) , twice ( watering at late jointing and heaoling stages ) and three ( watering at late jointing, heaoting and grain filling stages ) times.The results showed that the 1000-grain weight in the treatments of removing leaves were very significantly less than which in the treatment of no removing leaves , the 1000-grain weight was the highest under no irrigation condition and the rate of descend was the maximum under irrigate twice condition.In the later period of wheat , maintaining larger photosynthetic leaves area and proper irrigation was important to improve 1000-grain weight.
