烟叶不同部位成熟度与质量的关系

通过研究不同部位烟叶成熟度与烟叶质量的相互关系,以确定田间烟叶成熟度标准和直观的量化指标。研究结果表明,上、中部烟叶烘烤前后的鲜干比有随成熟度提高而降低的趋势;不同成熟度处理对烟叶烤前和烤后长宽比的影响没有明显规律;从中上等烟比例、均价、烟叶化学成分协调性及评吸结果来看,下部烟叶7～8成黄处理最好,中部烟叶8～9成黄处理最好,上部烟叶8～9成黄处理最好。

Relationship between maturity and quality in different parts of tobacco leaves

The paper studied the relationship of maturity and quality in different parts of tobacco leaves,in order to determine the maturity standards of field tobacco leaves and intuitionistic quantified index.The results showed that:the fresh stem ratio had the trend of reducing with the increasing of maturity before and after flue-cured tobacco baking in the upper,the middle parts;different maturity had no significantly affecting regularity on the aspect ratio before and after baking.The results of medium and classy ratio,average price,the coordination of chemical component,smoking results showed that the best stage of baking were 70%～80% of yellow in the lower tobacco leaves,80%～90% of yellow in the middler and upper tobacco leaves.
