摘    要:采集湖南主产烟区B2F、C3F、X2F3个等级烟叶样本559份,通过测定烟叶硫含量,研究了湖南烤烟硫含量的区域特征及烟叶硫含量与烟叶评吸质量评价指标间的量化关系.结果表明:湖南主产烟区烤烟硫含量范围为0.100%~2.106%,均值为0.884%,其中含量大于0.7%的样本占71.6%;在区域差异方面,烤烟硫含量由湘中高值区域逐渐向湘南和湘西北降低.随着烟叶硫含量的增加,烤烟的香气质、余味、燃烧性和灰色变差,杂气和刺激性增加,香味、吃味和评吸总分分值降低.受大量施用硫酸钾和大气硫沉降的影响,湖南部分烟区烟叶硫含量偏高,对烟叶品质产生负面影响,已成为目前影响烟叶质量提高的关键因素之一,在生产中应引起足够的重视.

关 键 词:烤烟    生态区域差异  评吸质量

Abstract:A total of 559 flue-cured tobacco samples with 3 grades(B2F,C3F and X2F) were collected from the main tobacco-growing areas in Hunan Province,and their sulfur contents were determined to study the regional characteristics of the sulfur contents and their quantitative correlations with the evaluation indices of smoking quality.The results showed that the sulfur content in the flue-cured tobacco was 0.100%-2.106%,with a mean of 0.884%.The samples with sulfur content above 0.7% accounted for 71.56% of the total.The sulfur content decreased gradually from the high sulfur content area of Central Hunan to South Hunan and Northwest Hunan.With increasing sulfur content in tobacco leaf,the aroma quality,aftertaste,combustibility and ash color went to bad,offensive odor and irritation property increased,and aroma taste,eat-taste and total smoking quality score fell down.Under the influence of applying larger amount sulfate potassium and of sulfur-type acid precipitation,the sulfur content in tobacco leaf was somewhat higher in partial areas of Hunan Province,and gave negative impact on tobacco quality,being one of key factors limiting the improvement of tobacco quality and ought to be attached enough importance in tobacco production.
Keywords:flue-cured tobacco  sulfur  eco-regional difference  smoking quality
