摘　　要：应用D-饱和最优回归设计，通过氮、磷、钾配比田间试验，建立烤烟施用氮、磷、钾对烤烟产量、产值及施肥利润的效应函数。试验结果表明：产量极大值氮、磷、钾优化施肥组合为N＝-0．2858，P2 O5＝-0．0710，K2 O＝0．0906，此时的产量为3080．14 kg/hm2。产值极大值氮、磷、钾优化施肥组合为N＝-0．9552，P2 O5＝-0．0149，K2 O＝0．3683，此时的产值为39513．59元/hm2。最佳施肥利润的氮、磷、钾优化施肥组合为N＝-1，P2 O5＝-0．0248，K2 O＝0．2840，此时烤烟的产量为2956．48 kg/hm2，产值为38174．43元/hm2，施肥利润为36710．92元/hm2。综合分析得出最佳的施肥组合范围为N 64．28 kg/hm2、P2 O5144．3～148．95 kg/hm2、K2 O 235．2～266．4 kg/hm2，即N∶P2 O5∶K2 O＝1∶（2．2～2．3）∶（3．6～4．1）。The effects of N-P-K ratio on the yield and production value of flue -cured tobacco variety Yunyan 100, as well as the benefit of applying N , P, K fertilizer were studied through field test by using D -saturation optimum regression design .The results showed that the optimum N , P2 O5 , and K2 O application level for obtaining the highest yield （ 3080.14 kg/hm2 ） was-0.2858, -0.0710, and 0.0906 respectively.The optimum N, P2 O5 , and K2 O application level for obtaining the maximum pro-duction value （39513.59 yuan/hm2） was -0.9552, -0.0149, and 0.3683 respectively.The optimum N, P2O5, and K2O appli-cation level for obtaining the highest fertilization benefit （36710.92 yuan/hm2） was -1, -0.0248, and 0.2840 respectively.Un-der the highest fertilization benefit , the yield of flue-cured tobacco was 2956.48 kg/hm2 , and the production value was 38174.43 yuan/hm2 .By comprehensive analysis , it was concluded that the optimum application rate of N , P2 O5 , and K2 O was 64.28, 144.3~148.95, and 235.2~266.4 kg/hm2, respectively, namely the optimal N-P2O5 -K2O ratio was 1∶（2.2~2.3）∶（3.6~4.1）.
