Abstract:

To improve the availability of upper flue-cured tobacco leaves in northern Guangdong, the appearance quality, chemical composition and sensory quality of upper flue-cured tobacco leaves were compared and summarized, changing planting layout, irregular cultivation technique, incorrect harvest maturity and baking techniques were analyzed as the influencing factors. The results showed that planting layout and cultivation techniques affected the ripeness of upper tobacco leaves in the field, the immature upper leaves affected the curing characteristics, and incorrect baking techniques produced immaturity leaves of cured tobacco. In this paper, the related technologies in cultivation, harvesting methods and baking modulation were summarized and analyzed. Therefore, it is pointed out that the key for improving availability of upper flue-cured tobacco leaves is to carry out the problem-oriented and systematic research from theory to application technology.

Key words: tobacco area of northern Guangdong, upper flue-cured tobacco leaves, availability, key technologies
