Abstract: This paper focuses on solutions to immaturity of upper leaves of tobacco cultivated in Wuping Tobacco Plantation Area and explores the standard degree of maturity for harvest. An experiment, based on comparison of results and analysis, was conduct on Yunyan 87 to investigate the appearance, quality, primary chemical compositions and related harmony, flavor and economic characters of flue-cured tobacco leaves. The experimental results show that optimal degree of maturity for harvest is 9~10, where appearance, quality, chemical compositions and related harmony and flavor reach the peak after the leaves are cured. Those flue-cured leaves highly meet industrial needs by virtue of optimal average price, proportion of first-class tobacco and economic benefits. Therefore, taking into account weather conditions and filed diseases, both quality of tobacco leaves and income of tobacco growers are expected to be improved by extending growth period of tobacco and harvest it when the degree of maturity reaches 9~10, instead of traditional standard of 8~9.
