Effects of different needle insertion height on flue-curing results of loose tobacco leaves

研究不同插针高度对散叶烘烤效果的影响,结果表明：采用背靠式分风板散叶烘烤,通过配套靠背加高杆调节插针高度烘烤平均长度为75.9 cm的鲜烟叶,插针高度55 cm的处理产生黑糟、蒸片、活筋等烤坏烟的比例明显降低,均价高,上等烟比例提高21.70~32.90个百分点,烟叶内在化学成分更趋于协调。

Effect of different needle insertion height on flue-curing result of loose tobacco leaves were studied in this paper.The results showed that adopted the treatment of back type air distributing plate leaf baking and supporting back mast pin to adjust needle insertion height with the average fresh tobacco leaves length of 75. 9 cm and pin height 55 cm,the ratio of producing black grains,steamed and gluten steamed decreased significantly and the average price was high,and the proportion of superior tobacco increased by 21. 70- 32. 90 percentage points and the intrinsic chemical composition of tobacco tended to be more harmonious.
