摘　　要：为探讨土壤质地与烟叶品质的关系,对4种土壤质地的170个土壤和烟叶样品进行了分析比较。试验结果表明,中等偏黏重质地为贵州省植烟土壤的主要类型。质地较轻的砂壤种植的烟叶具有高糖、低碱、高糖碱比和高氮碱比的特征;质地较重的粉黏土,其烟叶具有低糖、高碱、低糖碱比和低氮碱比的特征。由于黏性质地的土壤含有7%左右的砾石和适宜的养分含量,质地较重的烟叶评吸得分要略高于质地较轻的。In order to investigate the relationship between quality of flue-cured tobacco and soil texture,170 tobacco leaf samples and 170 soil samples of four types of soil texture were studied.The results showed the majority of tobacco planting soils in Guizhou province had texture of middle and moderately clay.Tobacco leaves planted on sandy loam was with characteristic of high sugar,low nicotine,high ratio of sugar to nicotine and high ratio of all nitrogen to nicotine.Tobacco leaves planted on silty clay was with characteristic of low sugar,high nicotine,low ratio of sugar to nicotine and low ratio of all nitrogen to nicotine.Because of suitable soil fertility and about 7% volume of gravelly in soil texture of high clay,the sensory evaluation score of tobacco leaf planted on heavy soil was better than those planted on light soil.
