开片降碱灵不同插签位置对烤烟产质量的影响

Effects of Different Insertional Position of Kaipianjiangjianling on Tobacco Yield and Quality

为改善烤烟上部烟叶品质,降低和控制上部烟叶烟碱含量,增加烟农收入,进行了开片降减灵不同插签位置对烟叶产质量影响的试验研究。结果表明,使用开片降碱灵签后,烟叶叶片长度和宽度增加显著;能显著地提高烟叶产量、产值,各处理间均价差异不显著。与对照相比,处理1、处理2和处理3烟碱含量分别下降17.92%、15.28%和12.26%,还原糖含量分别提高160.15%、129.21%和20.54%,叶质重分别降低7.6%、9.8%和13.68%,叶厚分别降低25.8μm、25.1μm和26.2μm,平衡含水率分别增加9.28%、7.86%和3.31%,自由燃烧时间分别缩短2.43 s、3.02 s和0.1 s,香气质、香气量上部叶略有降低,劲头明显改善,其余评吸指标相当。

The different insertional position of kaipianjiangjianling was tested to investigate the effect on tobacco yield and quality for improving upper tobacco quality and raising farmers＇ income. The results show that kaipianjiangjianling can significantly increase tobacco yield and output value by raising the tobacco length and width obviously and there is no significant difference between different treatments. The nicotin content of treatment 1, 2 and 3 decreases 17.92 %, 15.28 % and 12.26 %, the reduction sugar content increases 160.15 %, 129.21% and 20. 54%, the leaf weight and thickness decreases 7.6 %, 9.8% and 13.68%, and 25.8μ m,25.1 μm and 26.2 μm, the balance water content increases 9.28% ,7.86% and 3.31%, the free burning time of treatment 1, 2 and 3 shortens 2.43 s,3.02 s and 0.1 s compared with CK respectively.
