【摘要】[Objective]The research aimed to provide the theoretical basis for soil testing and formula fertilization of different tobacco-growing areas. [ Method] Based on \fertilizer experiment design, the effects of different fertilizer on flue-Cured tobacco growth, yield and quality were studied. [ Result ] The growth condition in field of different treatment tobacco plants had large difference. The content of total nitrogen, total nicotine and K3O in flue-cured tobacco had a closed relationship with different fertilizer effect. The different fertilizer effects had a large impact on economic characters of flue-cured tobacco. The flue-cured tobacco yield by the treatment of no fertilizer was lowest, and the ratio of mid-high grade leaves of flued-tobacco was higher. The economic characters of flue-cured tobacco by the treament of most N fertizer application rate didn' t show the best manifestation. [ Conclusion] The simulated three-factor equation of fertilizer effect was eatablished: Y = 138. 36 + 23. 18X1, -0. 83X12 -4. 32X2 +0. 34X22 -4. 40X3 +0. 09X32 - 1. 02X1X2 -0. 35X1X3 +0. 64X2X3(X1,X2 ,X3 represent the level of N,P3O5 and K2O fertilizer respectively). The research could guide local tobacco production by forecasting maximum fertilization
