| 摘 要： | 试验于１９９０～１９９２年在江苏农学院实验农场进行，供试品种（系）为扬麦５号、冀８４５４１８和８８７４．通过在小麦开花期喷施强力增产素，研究其对小麦花后干物质生产和产量的影响。结果表明：喷施强力增产素能延缓花后叶片的衰老，提高叶片叶绿素含量，增强光合功能，扩大花后干物质积累量，具有一定的增粒、增重作用。开花期喷施，可增产６．８２％～８．５６％，花后２０ｄ喷施效应下降，仅增产３．７３％。

| Abstract: | The effects of Yield-inereasing-regulator (YIR) on dry matter accumulation after anthesisand grain yield were studied.The main rcsults were as follows.Spraying YIR could delay the leavesscnescence,raise chlorophll content of leaves,and promote the photosynthetic rate afler anthesis;The drymatter accumulated after anthesis could be raised. Thercfore the grain number and weight could be in- creased. |
