湖北十堰野人谷基地单元中上部上等烟叶质量特征及其稳定性分析

Analysis on Quality Characteristic and Stability of Upper Fine Tobacco in Shiyan Savage Valley Base Unit of Hubei

[目的]考察湖北十堰野人谷基地单元烟叶质量状况。[方法]以云烟87为研究对象,对2010—2015年野人谷基地单元连续6年中上部上等烟叶外观质量、感官评吸进行分析。[结果]中上部上等烟叶外观质量与感官评吸质量较好,需要进一步提高烟叶油分,增加烟叶余味;中上部上等烟叶外观质量和感官评吸质量均较为稳定,年际间质量变化不大;建议采取减氮密植技术,控制烟碱,降低淀粉,提升化学成分协调性,提高烟气的细腻柔和程度;适量增施有机肥,提高烟叶的油分和结构疏松度,增加烟叶香气质、香气量,减轻烟叶杂气,从而进一步提升烟叶的外观质量和感官评吸质量,保障湖北中烟对优质特色烟叶原料的需求。[结论]该研究可为基地单元烟叶的品质改善提供参考。

[ Objective ] Tobacco leaf quality condition was investigated in Shiyan savage valley base unit of Hubei. [ Method ] Taking Yunyan 87 as the research object,appearance quality and sensory evaluation of the middle-upper fine tobacco were analyzed in savage valley base unit from 2010 to 2015. [ Result] The middle-upper fine tobacco appearance quality and sensory smoking quality were good,the oil content and tobacco aftertaste need to be further increased; The middle-upper fine tobacco appearance quality and sensory smoking quality were relatively stable, quality between the interannual change was not obvious ; Reducing nitrogen and close planting technology was suggested applying, it could control nicotine, reduce starch, improve chemical composition of coordination, increase the exquisite soft degree of flue gas;Increasing organic fertilizer application appropriately could improve tobacco leaf oil and gas porosity structure, increase tobacco flavor and quality of aroma, concentration of aroma, reduce mixed gas of tobacco leaves, so as to further enhance the tobacco leaf appearance quality and sensory smoking quality, guarantee the need of high quality characteristic tobacco raw material of Hubei China Tobacco. [ Conclusion ] The research can give reference for improving tobacco leaf quality of base unit.
