Abstract: With the treatments of seeping and sprinkler irrigation in winter wheat field, taking less irrigation as a check, the movement characters of soil water and its effects on wheat yield formation under different irrigation methods were studied. The soil water consumption of seeping irrigation in the layer of 0～20cm was less than that of sprinkler. The soil water content of the surface layer of 0～20cm in seeping irrigation field was lower during the whole growing season and the soil water consumption of seeping irrigation in the layer of 20～120cm was more than that of sprinkler. The soil water in the layer below the depth of 120cm was less used by wheat both in the two irrigation ways than the upper layers. The change of soil water in the layer below 120cm was small. The yield of seeping irrigation was increased by 11.6% and 17.6% compared with sprinkler and less irrigation, respectively. Seeping irrigation could save water by 57.1% compared with sprinkler irrigation. Its water use efficiency was 1.35 times of sprinkler irrigation method.
