摘　　要：以‘荷兰15’为供试马铃薯品种,采用二次通用旋转组合设计,建立氮肥(X1)、磷肥(X2)和钾肥(X3)三因子的回归数学模型,通过方差分析和数学模型优化得到施肥的优化区间。结果表明,三项肥料因子对马铃薯产量影响的大小顺序依次为:钾肥(X3)>氮肥(X1)>磷肥(X2);马铃薯产量大于2 782.04 kg/667m^2的肥料施用量优化区间为:N 16.755~24.675 kg/667m^2、P_2O_5 8.36~11.64 kg/667m^2、K_2O 42.24~48.48 kg/667m^2。The potato variety ＇The Netherlands 15＇ was tested using two general revolving combination design, and three factors regression mathematical model of nitrogen （Xl）, phosphorus （X2） and potassium （X3） was established and the optimized range of fertilization by the analysis of variance and mathematical model optimization were obtained. The results showed that the order of three fertilizer factors on potato yield was K （X3） 〉 N （Xl） 〉 P （X2）. When the optimized range of nitrogen fertilizer （N） were 16.755- 24.675 kg/667m2, phosphorus fertilizer （P2O5） 8.36- 11.64 kg/667m2, and potassium fertilizer （K20） 42.24 - 48.48 kg/667m2, the yield could be more than 2 782.04 kg/667m2.
