| 摘 要： | 采用二次回归通用旋转组合设计方法，对沙地春玉米水肥因子进行了试验研究，结果表明，试验条件下沙地农田土壤相对含水量保持在66.6%。施用尿素量59.4g/m^2时可获得1.13kg/m^2的最高产量，影响春玉米产量形成的关键因子是N肥施用量和土壤相对含水量。春玉米产量（Y）——与土壤相对含水量（X1）、N肥施用量（X2）的关系为Y=4.1 0.54X1 0.46X2-0.23X1X2-0.24X21-0.16X^22。

| Abstract: | 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. |
