摘要： 为探寻大花生新品种‘青花7号’的最佳施肥方案，采用三因素二次回归通用旋转组合设计方法，建立了氮、磷、钾施肥量与产量关系的效应方程。通过对回归方程的检验及效应分析，探讨了氮、磷、钾肥的单因子效应、互作效应和最佳施肥量。结果表明，施氮、磷、钾肥对花生产量具有明显的增产作用，其肥料效应顺序为钾肥>磷肥>氮肥；氮磷互作对花生产量的影响为极显著。对于试验地块种植的花生新品种‘青花7号’获得高产的最佳施肥组合为：氮肥106.08~133.92 kg/hm2，磷肥159.12~200.88 kg/hm2，钾肥为138.28~161.72 kg/hm2。

Abstract: A mathematical model was established to find the optimum fertilization scheme of peanut new variety (‘Qinghua No.7’) with the design of ordinary second order rotational regression of three factors, in which N (nitrogen), P (phosphorus) and K (potassium) were independent variables and peanut yield were dependent variables. It discussed the single factor effect, interaction effect and best fertilization of N, P and K fertilizer through the inspection of the regression equation and effect analysis. The results showed that N, P and K fertilizer had significant influence on yield increasing of peanut, and the rank of factor effects on peanut yield was K(X3) >P(X2) >N(X1). The interactions of N and P for peanut yield were extremely significant. The optimum application rates for‘Qinghua No.7’achieving high yield were the best combination of fertilizer application: N fertilizer 106.08-133.92 kg/hm2, P fertilizer 159.12-200.88 kg/hm2, K fertilizer 138.28- 161.72 kg/hm2.
