Effect of Different Water Treatments on Growth and Yield of Winter Wheat

LI Xiao-dong et al(Institute of Farmland Irrigation,Chinese Academy of Agricultural Sciences,Xinxiang,Henan 453003)  
[Objective] The study aimed to seek for the irrigation mode suitable for the water requirement of winter wheat in Huanghuaihai area.[Method] With Zhengmsi 98 as tested material,the drought treatments to different extent were carried out in 6 growing stages of winter wheat to study the effects of different water treatments on growth and yield in winter wheat.[Result] The water deficiency to different extent in different growing stages had different effects on plant height,final filler,leaf area and dry matter accumulation in winter wheat and the water deficiency in growth prophase(seedling,wintering and the turning green stages) of winter wheat had litter effects on plant height,final filler,leaf area and dry matter accumulation after the normal irrigation was recovered.The lower irrigation limit was 45% of field water-holding capacity during growing prophase of winter wheat and the lower irrigation limits were controlled by 65%,70% and 65% resp.in stages of jointing,heading and flowering,and filling and ripening,which was a proper irrigation mode for water requirement of winter wheat in Huanghuaihai area.[Conclusion] The irrigation mode presented by this study increased the yield and water use efficiency in winter wheat remarkably.
