| 摘 要： | 高产条件下冬小表施肥前氮后移,可以明显提高单位面积上的产量。本文研究了前氮后移施肥对小表旗叶生理功能的影响,结果表明,前氮后移施肥可以提高旗叶叶绿素和蛋白质含量,减少(?)的产生,MDA含量降低,使叶片衰老延缓,旗叶功能提高,产量增加。

| Abstract: | N application at late growth stage could inerease the wheat yield greatly un-derhigh-yield condition . It is studied that the effect of N application at late growth stage onphysiological function of flag leaf in this artile . The result showed that N applocation at late growth stage could in crease the chlorophgll and protein content of flag leaf . decrease the produse of O2 and malondia dehyde (MDA) accumulation ,retard the leaf growing old,increase the function of flag leaf.raise the yield. |
