以云烟87、K326、黔西1号、毕纳1号、南江3号、韭菜坪2号、杜鹃1号品种为材料,在贵州省毕节市江苏中烟大方基地单元开展品种筛选试验。在对比分析毕节大方与国内外优质烟区气候相似性的基础上,研究不同烤烟品种烟叶化学指标可用性与感官质量,对烟叶质量作出综合评价,为卷烟工业引导基地单元的种植品种提供理论支撑。结果表明,大方与三明、津巴布韦、巴西的气候条件具有很高的相似性,夹角余弦值在0.95以上,与三明的相似性最高,达0.98;云烟87的烟叶化学指标可用性指数最大,为92.14%,且感官质量表现最好。总的来看,江苏中烟大方基地单元最适宜种植云烟87。
A variety screening experiment was carried out in Yunzhai 87, K326, Qianxi 1, Pina 1, Nanjiang 3, leek Ping 2 and Rhododendron No. 1 in the unit of Generous Base of Jiangsu Tobacco in Bijie City, Guizhou Province. Based on the comparative analysis of climate similarity between Bijie and other high-quality tobacco areas, the availability and sensory quality of different tobacco varieties were studied, and the quality of tobacco leaf was evaluated comprehensively to provide theoretical support for the tobacco industry to guide the cultivation of the base unit. The results show that the climatic conditions of generous and Sanming, Zimbabwe and Brazil have very high similarity, and the cosine of included angle is above 0.95, which has the highest similarity with Sanming, reaching 0.98. The availability index of tobacco chemical index of Yunyan 87 is the highest, which is 92.14 %, And the best sensory quality. In general, units at Jiangsu Zhongyan Generous Base are most suitable for planting Yunyan87.
