Abstract: In order to learn more about the impact of the nitrogen adjustment method for insect prevention on the mellowing quality and mechanical property of tobacco leaves , the appearances, physical and chemical indicators, smoking quality and mechanical properties of Yunnan flue-cured leaves DBBFAPK processed by the routine insect prevention and nitrogen adjustment insect prevention were tested and comparatively analyzed. The results showed that the mechanical properties, appearance and smoking quality of the tobacco leaves processed by the two treatments were not significantly different. In terms of physical and chemical indicators, the total sugar of the nitrogen adjustment method was higher than that of the routine method, and the total nitrogen and nicotine were lower than that of the routine method.

Key words: nitrogen adjustment, tobacco leaves, mellowing quality, mechanical property
