　　Abstract In view of the problems in fertilization in Wenshan， which hindered the sustainable development of tobacco leaf quality and was difficult to meet the requirements of cigarette enterprises for higher quality of raw tobacco， the effects of optimized fertilization on growth and development of tobacco plant， yield and quality of tobacco leaves were studied in this paper. From the growth and development of tobacco， plant agronomic traits were relatively better by adjusting the proportion of base fertilizer to topdressing one； tobacco mature yellowing， biomass accumulation and resistance were improved by optimizing the nutrient ratio， and fewer differences were found between different treatments. Compared to the conventional fertilization， the economic benefit was the best when the nutrient rate was optimized； the chemical compositions were more conducive to improving the quality of tobacco leaves with lower total sugar content and ratio of sugar to nicotine after optimization of nutrient ratio and ratio of base fertilizer to topdressing one. Smoking assessment results showed that the comprehensive score and quality of flue-cured tobacco were the highest through nutrient ratio adjustment， the second was that through the ratio adjustment of base fertilizer to topdressing one， and that was the lowest under the conventional fertilization. The total score of flue-cured tobacco of the three optimization treatments were 1.98， 5.62 and 3.22 more than that of control respectively， and the quality was improved by two grades compared to the control. In conclusion， the local existing fertilization mode still had optimizing room； all the optimized fertilization treatments in this test showed obvious effects on improving quality and increasing yield especially the optimization of nutrient ratio.
