贵州省毕节地区韭菜坪2号烤烟新品种(系)烟叶质量分析与评价

Primary Analysis and Evaluation on Quality of New Flue-cured Tobacco Variety Jiucaiping 2 in Bijie Region

[目的]为毕节地区特色烟叶的开发及烤烟新品种韭菜坪2号的推广提供依据。[方法]以K326为对照,分析烤烟新品种韭菜坪2号的烟叶外观质量、初烤烟叶的化学成分、经济性状,量化烟叶的感官质量,综合评价韭菜坪2号的烟叶质量。[结果]韭菜坪2号的杂色烟较少,成熟度较好,香气值较高,相同等级烟叶的总糖和还原糖、淀粉含量高于对照,烟碱和总氮含量低于对照,钾/氯比更协调,蛋白质含量与对照相当,产量、均价、产值等经济性状高于对照。[结论]与K326相比,韭菜坪2号的外观质量和内在感官质量总体水平略好,初烤烟叶化学成分较协调,烟叶经济产量高,初步工业验证评价较好,但栽培和调制措施有待进一步完善。

[Objective] The purpose was to provide the basis for the development of characteristic tobacco and extension of the new flue-cured tobacco variety of Jiucaiping 2 in Bijie region. [Method] With K326 as CK, the appearance quality of flue-cured tobacco, chemical composition of cured tobacco leaves and the economic characters, sensory quality of quantitative tobacco leaves in the new flue-cured tobacco variety Jiucaiping 2 were analyzed and tobacco leaf quality was comprehensivelly evaluated. [ Result] The variegated tobacco of Jiucaiping 2 was less with good maturity and higher aroma, the contents of total sugar, reducing sugar and starch of tobacco with the same grade were higher than that of CK, the contents of nicotine and total nitrogen were lower than that of CK, the potassium/chlorine ratio was mare hannenious, the protein content was equivalent to CK, and the economic characters of output, mean price and production value were higher than CK. [ Conclusion] Compared with K326, the general level of appearance quality and inherent sense for Jiucaiping 2 was slightly better, the chemical composition of cured tobacco leaves was harmonious, economic output of tobacco leaves was high and appraisal on preliminary industrial verification was good, but cultivation and modulation measures should be further improved.
