烤烟上部烟叶一次性带茎采烤对烟叶产质量的影响

以烤烟上部5片烟叶（上部叶从上往下5片叶）为对象,研究上部叶一次性带茎采烤与上部烟编烟采烤两种采烤方式对烟叶产质量的影响。结果表明,上部叶一次性带茎采烤烤后烟叶质量、中上等烟叶比例及其产值有所提高,但平均烘烤增加14.7 h,用工成本增加,烘烤成本为每炉895元。结合当地实际情况,认为旬阳烟区目前不适宜推广上部烟叶一次性带茎采烤技术。

Effects of One-Time Harvesting and Flue-Curing of Tobacco Upper Leaves with Stem on Its Leaf Yield and Quality

The results showthat the leaf quality, the proportion of better-than-average leaves and the production value have somewhat been increased by means of the one-time method abovementioned, but accordingly the average time for flue-curing has increased by 14.7 h, so has the labouring cost at 895 yuan per flue-curing furnace.
