Abstract: To solve the problem of deficit soil organic matter in tobacco planting area and decreasing quality of flue-cured tobacco, with different kinds of organic fertilizers as experimental material, we adopted the method of field experiment to study the growth and quality of flue-cured tobacco. The results showed that: compared with local conventional compound fertilizer, 750 kg/hm2 oil cake organic fertilizer and 600 kg/hm2 straw organic fertilizer could promote the growth of tobacco, increase the yield and improve the coordination of tobacco leaves. Compared with conventional fertilization, the yield under the application of oil cake organic fertilizer was increased by 2.6%, the output value increased by 13.9%, and the average leaf area increased by 14.5%. Compared with conventional fertilization, the application of straw organic fertilizer increased the yield by 0.6%, increased the output value by 5.4% and the average leaf area by 36.6%. Organic fertilizer and chemical fertilizer could increase the potassium content in tobacco leaf, reduced nicotine content, and improve the proportion of better than average tobacco leaves, thus to increase the tobacco output value.
