摘要
为进一步了解上部烟叶烘烤特性,探究叶片与主脉失水的动态协调关系,采用高温高湿变黄的方法,研究了上部叶烘烤过程中叶片与主脉含水率变化对烟叶烘烤质量的影响。结果表明,变黄期处理与对照均易变黄,定色期处理定色效果较好,干筋期对照主脉较难干燥,处理烤后上等烟比例明显高于对照。变黄期通过高温高湿的方法使叶片凋萎与主脉发软同步,能够有效提高烤后烟质量,从而提高上部叶的可用性。
In order to further understand the upper tobacco curing characteristics, explore the dynamic coordination between the blade and the main vein dehydration, the effects of moisture variation of blade and main veins on the quality of tobacco during the baking process of upper tobacco leaves were studied by using the method of high temperature and humidity yellowing. The results showed that, during the yellowing period, the treatment and the control were easy to turn yellow; during the stage of fixing color, fixing color effect of the treatment was better than the control; during the stem drying period, the drying for main vein of the control was more difficult; after baking, the first-class tobacco proportion of the treatment was higher than the control. During the yellowing period, the wilting of leaves synchronized with the softening of main veins under high temperature and high humidity, which could effectively improve the quality of the flue-cured tobacco, so as to increase the availability of the upper leaves.
