小麦不同剪叶处理试验结果表明：（１）剪剑叶、倒二叶、倒三叶３处理的灌浆期物质生产量分别较对照降低１６．２４％、１５．４１％、１１．６９％；（２）剪叶处理后由于净同化率的提高，对灌浆期的物质生产有一定的补偿作用，净同化率的提高幅度为１０％～１５％；（３）剪叶处理对灌浆速率有不同程度的影响，进而影响了单穗籽粒重，剪剑叶、倒二叶、倒三叶３处理的单穗籽粒重分别较对照降低３３．６４％、２４．８６％、１７．７０％，三叶全剪处理的单穗粒重较对照降低４２．６９％；（４）剪叶处理在影响灌浆期物质生产的同时，影响灌浆期物质向籽粒的运输是导致籽粒产量下降的共同因素。
The results of different treatments of cutting leaf in wheat showed that: (1) The material yield of grain filling during the treatments of shearing, inverting and inverting three treatments were reduced by 16.24%, 15.41% and 11.69%, respectively; (2) As the net assimilation rate increases after the leaf cutting treatment, it has a certain compensation effect on material production in the filling stage, and the net assimilation rate is increased by 10% -15%; (3) The grain weight of single ear was affected, the grain weight of single ear was decreased by 33.64%, 24.86% and 17.70% respectively compared with the control, The grain weight per spike under full leaf shear treatment was reduced by 42.69% compared with the control. (4) Leaf cutting treatment affected the material production at grain filling stage, while the transport of material to grain during grain filling stage was the common factor leading to the decrease of grain yield.
