【摘要】The main chemical compositions and the chemical harmony indices of flue-cured tobacco from different soil types were studied in Xuanwei tobacco planting region, and the chemical quality of flue-cured tobacco from different soil types were evaluated base on fuzzy mathematical method. The results showed that there were significant differences of main chemical compositions of tobacco among different soil types, which were as follows: tobacco from paddy soil had the highest contents of total sugar, reducing sugar, total nitrogen and nicotine; tobacco from new alluvial soil had the highest contents of potassium and chloride and ratio of sugar to nicotine; tobacco from purple soil had the highest starch content, difference between two sugars and K/Cl; tobacco from red soil had the highest ratio of nitrogen to nicotine. Therefore, tobacco from red soil had the highest chemical harmony score (CHS) of flue-cured tobacco (79.74), and followed by new alluvial soil and purple soil, paddy soil had the lowest.%对云南宣威烟区不同土壤类型上烤烟的化学成分及其协调性进行了研究,并采用模糊数学方法对烤烟化学质量进行综合评价.结果表明:不同土壤类型上烤烟的主要化学成分存在极显著差异,总糖、还原糖、总氮和烟碱含量均以水稻土最高,烤烟钾含量、
