Through contrast experiments

soil evaporation and water use efficiency of winter wheat after applying soil amendment fertilizer were studied using the method of farmland water balance and micro-lysimeter. Results indicated that after applying soil amendment fertilizer

the mean water consumption of winter wheat during the growth period decreased by 491.67 m3/hm2 averagely

compared with the contrast. Soil evaporation of winter wheat and the ratio of soil evaporation to water consumption during the stage from seeding to jointing also decreased. The water use efficiency was 2.62 kg/m3 under the treatment of 2 250 m3/hm2 irrigation water and the yield increased by 32.68% under the treatment of 1 950 m3/hm2 irrigation water.
