| Abstract: | By using experimental data of winter wheat planted in lysimeters in 2001 - 2002, the effects of irrigation treatments in different growth stage on the grain yield constituents and water use efficiency of winter wheat were studied . Based on analyzing the experimental results, the optimal irrigation scheduling and optimal soil water index in growth stage were put forward. It is significant to realize the unification of water-saving and high yields of winter wheat in the North China Plain where the water resource shortage is becoming a major problem. |
