曲靖烟区烤烟主栽品种海拔适应性研究

摘要

运用简单相关、方差分析和主成分聚类统计分析方法，研究了曲靖烟区主栽烤烟品种初烤烟叶外观质量、化学成分和评吸质量与种植海拔高度的关系，结果表明：（1） K326、红大、云烟97对种植海拔高度的敏感性由高到低为：云烟97、K326、红大；烟叶外观质量、化学成分含量比评吸质量对海拔更敏感；（2）在1350～2250 m范围内，烟叶颜色和油分与海拔呈显著或极显著正相关，刺激性、余味、燃烧性、灰色、浓度、劲头、总氮、烟碱和钾含量与海拔呈显著或极显著负相关。综合分析得出，曲靖烟区K326在1400～1600 m和1800～2100 m、红大在1600～1700m和2100～2250 m、云烟97在1300～1400 m和2000～2250 m海拔段烟叶外观质量、化学品质和评吸质量较好，为适宜种植海拔段。%The relationships between appearance quality , chemical components , sensory evaluation index and planting altitude of tobacco in Qujing were investigated through simple correlation ,variance and principal component cluster analysis .The result indicated that:(1) the sensibility of flue-cured tobacco varieties to alti-tude decreased in order of Yunyan 97>K326>Hongda;leaf appearance quality and chemical components were more sensitive to altitude than smoking quality;(2) from 1 350 m to 2 250 m,there were significant or ex-tremely significant positive correlations between leaf color ,oil and altitude;there were significant or extremely significant negative correlations between leaf biting taste ,after taste,combustibility,ash,concentration,strength energy ,contents of total N ,Nicotine,K and altitude .In summary ,the integrate analysis showed that the leaf ap-pearance quality ,chemical components and smoking quality of K 326 were optimum at 1 400-1 600 m and 1 800-2 100 m,while those qualities of Hongda were at the altitude of 1 600-1 700 m and 2 100-2 250 m, and those of Yunyan97 were at the altitude of 1 300-1 400 m and 2 000-2 250 m in Qujing .
