Abstract
In order to understand the influences of irrigation during mature stage on upper leaf expanding condition, and physical characters and chemical components of cured tobacco leaves, three different irrigation management methods during mature stage were conducted to K326. The results indicated that after irrigation during maturation stage, the upper leaf area increased, the condition of leaf expanding was better, and the physical characters of tobacco leaf was great(the contents of reducing sugar and total sugar in tobacco leaf increased, and the contents of total nitrogen and nicotine decreased). Especially irrigated during squaring stage, topping stage and round top stage, the harmony of the chemical component in tobacco leaves enhanced significantly, the contents of neutral aroma components were plentiful. Therefore,irrigation during mature stage is available to improve the quality of tobacco leaves.
