%X Experiment of different stored water of soil before sowing were conducted in dryland of east Gansu. The results show that the winter wheat yield has interrelated significantly with the stored water of soil before sowing in 0- 200cm soil layers. With the increasing of the soil stored water, the yield of winter wheat increases to 40.8% , the transpiration rate, photosynthetic rate, leaf area index, and efficiency of stored water in summer fallow raise.
