摘    要:目的]实现小麦优质高产节水省肥提供科学合理的水氮运筹模式。方法]在大田条件下,研究灌水次数及施N时期对小麦旗叶Pn、叶绿素荧光参数及产量的影响。结果]灌水次数对旗叶Pn、Fv/Fo、Fv/Fm、qP、qN及产量的影响均达到显著或极显著水平,且不灌水与灌水处理间差异较大;N肥全部基施与返青期追施(40%)处理间旗叶的Pn、Fv/Fo、Fv/Fm、qP和qN差异不大,但2个处理的光合参数与产量均明显低于拔节期或孕穗期追施(40%)处理。结论]灌水次数与施N方式对Pn、叶绿素荧光参数及产量性状的调控存在显著的互作效应,其中以W2N4处理组合效果最好。

Abstract:Objective] The aim was to provide a scientific and rational water,nitrogen model for achieving high yield,high quality of wheat and water and fertilizer saving.Method] Under the field conditions,the effects of irrigation frequencies and N application times on net photosynthetic rate(Pn),chlorophyll fluorescence parameters of flag leaf and yield of wheat was studied.Result] The differences on Pn,chlorophyll fluorescence parameters Fv/Fo,Fv/Fm,qP,qN of flag leaves and yield of wheat among different irrigation times had reached a significant level,and the difference between treatment without irrigation and irrigation treatments were relatively large;the difference on Pn,Fv/Fo,Fv/Fm,qP and qN between treatments of basal application of N fertilizer and N application(40%)in returning green stage was not significant,however,the photosynthetic parameters and yield of two treatments were obviously lower than that of N application(40%)in jointing stage or booting stage.Conclusion] The effects of irrigation frequencies and N application times showed significant interaction effects on photosynthetic characteristics of wheat flag leaves and yield,in which W2N4 treatment combination was best.
Keywords:Wheat  Irrigation frequency  N application time  Photosynthetic traits  Yield
