| 摘 要： | 为提高品种‘K326’上部叶烤后烟叶价值及内部化学成分协调性，在烟叶采收环节调整采收成熟度，在烘烤时采用定色期低速升温、高湿定色的烘烤工艺。研究表明：当上部叶充分成熟，叶色变黄，主脉泛白，茎叶角度在90°左右，在定色期采用低速高湿烘烤工艺，烘烤时间延长10 h以上，烘烤成本略有增加，烤后烟叶内部化学成分协调性较好，淀粉含量降低，可以达到预期的目标；当顶叶过熟，叶色变黄泛白，到达枯尖焦边的程度，在定色期采用低速高湿烘烤工艺，烤后烟叶均价较高，还原糖含量适中，淀粉含量5%左右，总氮含量适中，钾氯比适宜，内部化学成分协调性好。

| 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. |
