Abstract
A plot experiment was conducted to explore the effect of the basal and top dressing N ratio(10∶0and 6∶ 4)on the yield and physiological traits of winter wheat under regulated deficit irrigation.The results showed that water deficit from returning green to jointing stage significantly reduced leaf area of winter wheat,well water promoted root activity after heading stage,and reduced the accumulation rate of MDA content in flag leave after anthesis,which resulted in significant increase of water use efficiency and grain yield of winter wheat eventually.Compared with the treatment of basal N to top dressing N ratio of 10∶0,the treatment of basal N to top dressing N ratio of 6∶4significantly improved leaf area of winter wheat after anthesis,significantly increased photosynthetic rate of winter wheat during grain filling and reduced the content of MDA in flag leaf after anthesis under the progressive soil dying condition after heading stage.The treatment of basal N to top dressing N ratio of6∶4also increased yield stability.The results indicated that water deficit from returning green to jointing stage positively increase grain yield if soil water condition was well at the late growth stage,and increasing top dresseing N could potentially improve drought resistance of winter wheat when soil water condition was lower at the late growth stage.
