应用3类肥效模型和Monte Carlo法,对水稻＂3414＂田间试验结果进行分析。结果表明：3种肥料对产量的影响大小为N〉P〉K;N、P、K任意2种肥料在2水平施用时,均有利于第3种肥料肥效的发挥;最高产量和最高施肥利润的函数均为三元二次肥效函数,最高产量和最高施肥利润分别为8 567.92 kg/hm2和17 165.59元/hm2,对应的纯N、P2O5、K2O的比例分别为1∶0.51∶0.56和1∶0.52∶0.52;产量高于8 500kg/hm2的纯N、P2O5、K2O的推荐施肥量分别为151.11～185.43、75.65～96.65、81.81～108.12 kg/hm2,利润高于17 000元/hm2的纯N、P2O5、K2O推荐施肥量分别为120.97～157.24、62.12～83.95、59.01～86.52 kg/hm2。%Research on the Efficiency of ′3414′ fertilizer design on rice were carried on by using three kinds of fertilizer response models and Monte Carlo method.The results showed that the influence on the yield was NPK.Any two Fertilizer of N,P,K applied in middle level,which was in favor of the effect of the third fertilizer.The function of the highest yield and the highest fertilization profit was three-variable quadratic function,the highest yield and the highest fertilization profits were 8 567.92 kg/hm2 and 17 165.59 yuan/hm2,the N,P2O5 and K2O ratios of the corresponding were 1.00∶0.51∶0.56 and 1.00∶0.52∶0.52,the fertilization recommendations of higher yield than 8 500 kg/hm2 were 151.11～185.43 kg/hm2,75.65～96.65 kg/hm2 and 81.81～108.12 kg/hm2,the fertilization recommendations of higher fertilization profit than 17 000 yuan/hm2 were 120.97～157.24 kg/hm2,62.12～83.95 kg/hm2 and 59.01～86.52 kg/hm2.
