| 摘 要： | 本文对张掖市的熟地采用了通用旋转回归设计方法,研究了氮、磷二因子对熟地水稻产量的影响以及因子间的配合关系。根据试验资料。建立了二元二次回归产量模型，与实际资料拟合较好，达到了极显著水准。并通过对产量模型的分析，明确了在当前条件下以高产为目标时，各因子的适宜用量，明确了二因子在增产中的作用是磷肥大于氮肥。

| Abstract: | Effects of nitrogenous and phosphate fertilizers on the yield of rice growing on various long-cultivated land and the relation between the two nutrients were studied by revolving regression designed field experiment.Based on the experimental data a regressive yield model was established.Then by analysis of the model suitable rate of ap;lication of the two fertilizers on present condition can be determined.It was also concluded that for increasing rice yield phosphate fertilizer was more important than nitrogenous fertilizer. |
