%X The relationship between the corn yield and the soil water content, the application amounts of nitrogen and phosphate were studied by the general regressive method of rotary combination design. The results showed that the amounts of nitrogen and the soil water content are the sensitive factors for increasing corn grain yield. If the soil water content, the amounts of N is 66.6%,59.4g/m2 respectively, the highest corn yield will be 1.13kg/m2 under the experimental condition.The relationship between the corn yield(X2) and the soil water content(X1)and amount of nitrogen(X2) is as follows Y=4.1+0.54X1+0.46X2-0.23X1X2-0.24X21-0.16X22.
