摘要： 为了研究花后去叶对小麦千粒重的影响，通过在4种肥料处理下，以3个小麦品种为试验材料，分别进行不去叶（对照）、留旗叶+倒二叶、只保留旗叶、去旗叶、去所有叶片处理，研究不同氮肥施用量下叶片对千粒重的贡献率。结果表明，去叶处理对千粒重影响差异显著(P<0.05)，不同去叶处理千粒重均小于对照。结论为在4种氮肥处理下，不同去叶处理对千粒重的影响趋势一致，去叶处理对千粒重的影响大小依次为：去掉所有叶片>只保留旗叶>留旗叶+倒二叶>去旗叶。

Abstract: To study the effects of removing leaves after flowering on 1000-grain weight of wheat, through the treatments of reserving all the leaves (CK), reserving flag leaf and backward second leaf, reserving flag leaf, removing flag leaf, removing all the leaves, we studied the effects of wheat leaves on the 1000-grain weight in different quantity of N. The results showed that there were significant differences in the 1000-grain weight between different treatments of removing leaf (P<0.05), the 1000-grain weight in the treatments of removal leaf was less than which in the treatment of no removing leaf. The trend of 1000-grain weight was accordance under different nitrogen treatment. The effect of treatments of removing leaf on 1000-grain weight was in the following order: removing all the leaves > reserving flag leaf > reserving flag leaf and backward second leaf > removing flag leaf.
