不同氮素运筹对小麦光合生产的影响
he Effects of Photosynthetic Production under Different Nitrogen operations
本文选用多穗型小麦品种山农9801，研究不同氮素运筹对小麦光合生产的影响。结果表明，适当推迟追氮时期与加大追氮比例，能够满足小麦生长中后期对氮素较高的需求，提高旗叶叶绿素含量、加大旗叶净光合速率峰值、减缓后期群体光合速率的衰退。同一追肥时期不同基追比例间差异表现为3:7＞5:5＞7:3＞10:0；同一追肥比例不同追肥时期间表现为孕穗期＞拔节期＞返青期。
In this paper,the effects of Photosynthetic Production under different Nitrogen operations were studied.The results showed: with the transferred and raised of nitrogen recovery, the chlorophyll content and the net photosynthetic rate of flag leaf were raised. In the same period of time between the different performance-based recovery ratio for 3:7 (A3)>5:5 (A2)>7:3 (A1)>10:0 (A4).In the same period ,the proportion of the performance of the different top dressing for the booting stage>jointing stage>green period.
