摘要
为了解凤凰县烤烟化学成分特征,采用比较分析、聚类分析和模糊优先相似比分析等方法研究了凤凰县与国内外主要烟区的烟叶化学成分差异和相似性。结果表明:凤凰县烟叶具有糖高、钾较高、氮和氯低、烟碱适宜的特点,烟叶化学成分与中间香型的黔西南兴义最相似,其次与清香型产区的大理祥云、曲靖罗平相近,与浓香型产区的郴州桂阳、许昌襄县及国外烟叶津巴布韦、巴西差异较大。可推知凤凰县烤烟属于中偏浓香型。
The chemical components of flue-cured tobacco between Fenghuang and main domestic and overseas were studied by comparative analysis, clustering analysis and fuzzy preferred ratio in order to know the characteristic of chemical components of flue-cured tobacco in Fenghuang. The results showed that comparing with main domestic and overseas leaves, Fenghuang leaves were higher sugar, slightly higher potassium, lower nitrogen, lower chlorine and suitable nicotine. The similarity of chemical components of flue-cured tobacco was the highest between Fenghuang County and Xingyi City, southmest of Guizhou of pure-sweetness type, followed by Xianyun County, Dali and Luoping County, Qujing of fresh-sweetness type. The difference of chemical components of flue-cured tobacco was more between Fenghuang County and Guiyang County, Chenzhou, Xiang County Xuchang of burnt-sweetness type, and Zimbabwe and Brazil of overseas leaves. It was deduced that the aroma types of flue-cured tobacco in Fenghuang belonged to intermediary-to-intense fragrance.
