| 摘 要： | 试验应用四因素五水平二次正交回归组合设计方法,研究了施用氮、磷、钾、有机肥对水稻产量及其构成因子的影响。结果表明,氮、磷、钾、有机肥的合理施用对水稻产量及其构成因子有非常显著的影响。通过株高、干物重、产量等指标的分析得出,氮肥是影响水稻产量的主效因素。

| Abstract: | The experiment was designed of ordinary second order straight regression of four factors. Under the condition of experiment combined application of nitrogenous fertilizer (N), phosphate fertilizer (P), potash fertilizer (K) and organic fertilizer to rice was studied for its effects on yield and component factors. The results showed applying proper N, P, K, organic fertilization can significantly increase rice yield and yield. N fertilizer is primary factor of rice yield. |
