Abstract:

In order to improve the species ‘K326’ the value of the upper leaves of cured tobacco and the coordination of the internal chemical composition, adjustment link in the tobacco harvest maturity, in the baking, a constant color temperature of the low-speed, high humidity curing process color set. This research showed that: when the upper leaves of fully mature leaves turned yellow, the main vein white, leaf angle of 90°, in the given color with low speed and high humidity of the baking process, the baking time extended by 10 hours, a slight increase in the cost of curing, cured tobacco leaf was better coordination within the chemical composition, starch content decreased, reaching the expected target; when parietal overripe, color yellow white, sharp focus dry side to reach the degree of color in the set of low speed and high humidity curing process used, the higher the average price of cured tobacco leaves, reducing sugar content was moderate, the starch content 5%, total nitrogen content was moderate, potassium chloride than the optimum, and good coordination of the internal chemical composition.
