With Jingdong No.8 as control, the soil water consumption, root development, yield, WUE, etc.of 7 varieties of winter wheat were studied for two years.The results showed that reviving~jointing stage was critical to wheat, and the consumption rate is 3.4~4.0 mm/d. Jing 9428 and Zhonghan 110’s yield and WUE were higher and stable compared to the control.In Beijing's climate condition, three times irrigation during the whole growth period is necessary for relatively high yield of winter wheat. |
