摘要
本文探讨了小麦叶片生育后期衰老过程中的代谢变化以及抽穗期喷施氮肥、6—苄基腺嘌呤(6—BA)的影响。喷施氮肥、6—BA两处理明显地延缓了冠层叶片的衰老,促进基部小穗的灌浆,提高结实性。
This paper illustrates the metabolic changes of wheat leaves during laten period senescence, and the effects of spraying solution(2% urea and 10ppm 6-BA)at the time cf heading. Spraying solution can significanly postpone the leaf senescence, promote kernel filling of base spikelets, increase the yield of wheal.
