１９９４～１９９６年对高产冬小麦前氮后移施肥方式的产量效应和生理变化进行了研究。结果表明，采用此施肥方式可以减缓旗叶中超氧化物歧化酶（ＳＯＤ）活性下降和脂质过氧化产物丙二醛（ＭＤＡ）含量的积累，减少超氧阴离子（Ｏ２）的产生，提高旗叶叶绿素和蛋白质含量，延缓叶片衰老，显著增加穗粒重和产量。
From 1994 to 1996, the yield and physiological changes of high yield winter wheat before N fertilizer application were studied. The results showed that the decrease of superoxide dismutase (SOD) activity and the accumulation of malondialdehyde (MDA) in flag leaves and the production of superoxide anion (O 2) Flag chlorophyll and protein content, delayed leaf senescence, significantly increased ear grain weight and yield.
