摘　　要：通过棉花氮、磷、钾"3414"田间试验测得的数据,分别建立获嘉位庄高产田、延津东屯中高产田、卫辉虎头庄中低产田以籽棉产量为目标函数的氮、磷、钾三元二次回归模型,通过模拟仿真因素取值的频率分析,分别求得3个试点高产的N、P2O5、K2O最优施肥配比为:位庄高产点施N 380.3～394.94 kg/hm2、P2O5192.81～200.23 kg/hm2、K2O 297.80～311.4 kg/hm2,籽棉产量可达4 456.07～4 483.42 kg/hm2;延津东屯中高产点,施N 94.08～112.54 kg/hm2、P2O5 48.85～59.0 kg/hm2、K2O 263.34～277.96 kg/hm2,期望产量为3 906.63～3 962.18 kg/hm2;卫辉虎头庄中低产点,施N 243.76～271.59 kg/hm2、P2O5 210.48～214.00 kg/hm2、K2O 286.73～301.02 kg/hm2,期望产量为3 317.41～3 352.80 kg/hm2。并对各类模型的两因素互作效应及单因素效应作了剖析。The data from 3414 fertilizer effect experiment of cotton about nitrogen,phosphorus and potassium were used to establish the regression model for the high-yield field in Weizhuang Village,Huojia,medium-high-yield field in Dongtun Village,Yanjin,and low-yield field in Hutouzhuang Village,Weihui,respectively.Through the frequency analysis method by simulating factors,the optimum fertilizer rate of N,P2O5 and K2O for high-yield field was 380.3-394.94 kg/hm2,192.81-200.23 kg/hm2 and 297.80-311.4 kg/hm2,respectively,and the seed cotton yield could reach 4 456.07-4 483.42 kg/hm2.The optimum fertilizer rate of N,P2O5 and K2O for medium-high yield field was 94.08-112.54 kg/hm2,48.85-59.0 kg/hm2 and 263.34-277.96 kg/hm2,respectively,and the seed cotton yield could reach 3 906.63-3 962.18 kg/hm2.The optimum fertilizer rate of N,P2O5 and K2O for medium-low yield was 43.76-271.59 kg/hm2,210.48-214.00 kg/hm2 and 286.73-301.02 kg/hm2,respectively,and the seed cotton yield was 3 317.41-3 352.80 kg/hm2.The interaction effect of two factors and the single factor effect in each modal were also analyzed.
