Abstract：Water resource shortage in North China is serious. A experiment studying yield improving and water-saving effects of several soil fertilization patterns were carried out. The results showed that vield on field with all corn and wheat straw kept down and tilled into soil(referred as Treat A)is 477.72 kg/hm2 higher than that on field with only wheat straw kept down and tilled into soil(referred as Treat B),a raising of 3.62%. The water consumption in Treat A was higher than that in Treat B in winter wheat season, and was opposite in summer corn season. Total Water consumption of winter wheat and summer corn in Treat A was higher than that in Treat B, but the water use efficiency values in two treats is nearly the same. On the experimental data, optimum fertilization pattern can be set up as: all straw kept down and tilled into soil+N2 level+organic fertilizer. Under this fertilization pattern, total water consumption of two growing seasons were 778.34 mm, and water use efficiencies were 19.00 kg/(hm2·mm).
