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。
In this paper, a general rotation regression method was applied to ripe land in Zhangye city. The effects of nitrogen and phosphorus on the yield of cooked rice and the relationship between factors were studied. According to the experimental data, a binary regression yield model was established, which fitted well with the actual data and reached a very significant level. And through the analysis of production model. Clearly under the current conditions to high-yield as the goal, the appropriate amount of each factor, it is clear that the role of two factors in the increase in production is more phosphate fertilizer than nitrogen.
