Abstract: To seek new ways to improve the quality of tobacco, a field experiment was conducted to study the effect of vermicompost and vinasse on improving the growth and chemical properties of flue-cured tobacco using K326 as materials. Six treatments were set up, which were CK (conventional fertilization);T1(vermicompost 2 400 kg/ha);T2(vermicompost 1 800 kg/ha and vinasse 600 kg/ha);T3(vermicompost 1 200 kg/ha+vinasse 1 200 kg/ha);T4(vermicompost 600 kg/ha+vinasse 1 800 kg/ha);T5(vinasse 2 400 kg/ha),respectively. The results showed that vermicompost and vinasse could improve the plant growth, enhance the agronomic traits and chemical component of flue-cured tobacco, especially for the T2 (vermicompost 1 800 kg/ha and vinasse 600 kg/ha). The content of total nitrogen, total potassium and sugar content at topping stage were increased by 60.60%, 46.37% and 7.80%, while those at maturing stage were increased by 14.86%, 34.59%, 32.50%, as compared with CK, respectively. It also exhibited appropriate chemical property under T2 treatment. In conclusion, applying with vermicompost 1 800 kg/ha and vinasse 600 kg/ha can be suggested as a suitable fertilization models in tobacco-growing areas in Southern Shaanxi Province.
