Effects of Different Water Treatment on Winter Wheat Photosynthetic Physiology

[Objective]The research aimed to provide the theoretical basis for the proposal of the cropland water irrigation program suitable for the environment.[Method]Under pot experiment conditions,in jointing stage,flowering stage,filling stage of winter wheat in all the different water treatments,the effects of different water treatment on photosynthesis of wheat were studied.[Result]The different water treatments had impacts on wheat transpiration rate,photosynthetic rate,water use efficiency and so on.Compared with low water treatment,the transpiration rate and photosynthetic rate were more obvious,different water treatments of winter wheat in the optical and physiological indexes including the transpiration rate,stomatal conductance,photosynthetic rate,intercellular CO2 concentration and water use efficiency had great influence,and only minor effects on the blade temperature.[Conclusion]The research was conductive to realize the effective utilization of the water,and achieve the goal of saving water and the achievement of the high yield.
