根据二次旋转回归试验结果,建立了氮磷钾三要素与亩产量关系的数学模型;得出三者对产量的影响为:磷肥 >氮肥>钾肥,并模拟筛选出不同试验条件下获得高产时氮磷的适宜范围;对各单因子效应也进行了分析。
According to the results of quadratic rotation regression, a mathematical model of the relationship between NPK and yield per mu was set up. The results showed that the three effects were: phosphate fertilizer> nitrogen fertilizer> potassium fertilizer, and simulated the high yield under different experimental conditions The appropriate range of nitrogen and phosphorus; the single factor effects were also analyzed.
