为研究恩施烟区烤烟的主要农艺性状与经济性状的相关关系，明确影响烤烟经济性状的主要因素，采用灰色关联度分析法，对3种肥力烟田烤烟农艺性状与经济性状之间的关系进行了分析。结果表明，高肥力水平下株高和有效叶数对烤后烟叶的产量和产值影响较大，其次为茎围、上部叶面积和中部叶面积。中等肥力水平下烟株的茎围与产量、产值和均价等经济性状指标的关联度较大，其次为有效叶数、中部叶面积和株高；低肥力水平下，烟株节距是影响烤后烟叶产量、产值以及上等烟比例的重要因素，其次为有效叶数。在恩施烟区实际烤烟生产中，可根据与经济性状的关联度较大因素，改进烤烟生产技术措施，进而提高烟叶经济效益。

To explore the relationship between agronomic and economic characters of flue-cured tobacco in Enshi tobacco-growing areas, and identify the major impact factors of tobacco economic character, the correlations between agronomic and economic character of tobacco under three fertility levels were determined by use of grey correlation analysis. The results showed that the leaf yields and output value affected strongly by plant height and leaf number under high fertility level, the stem thickness, the upper leaf area and middle leaf area also affected leaf yields and output value. The grey correlation degree was high between the stem thickness and leaf yields and output value, average price of flue-cured tobacco under middle fertility level. The leaf number, the middle leaf area and plant height also had a high grey correlation degree. The distance between internodes were an important impact factor on leaf yields, output value and proportion of superior leaves of flue-cured tobacco under low fertility level and the leaf number was also an impact factor. These results are significant for improving production technical measures and increasing economic values of flue-cured tobacco in Enshi tobacco-growing areas.
