摘　　要：为了研究土壤理化性质对烟叶中巨豆三烯酮的影响,为选择适宜的植烟土壤提供理论依据,笔者通过灰色关联度分析研究烟叶中巨豆三烯酮含量与土壤理化性质之间的关系。结果表明:土壤砂粒含量和p H对巨豆三烯酮含量影响最大,其中砂粒含量与巨豆三烯酮符合二次曲线变化规律;其次是交换性钙、交换性镁;碱解氮、速效磷、速效钾与巨豆三烯酮关联度较小。In order to study the effect of soil physico-chemical properties on megastigmatrienone content offlue-cured tobacco leaves and provide theoretical foundation for the selection of suitable tobacco-planting soil,the relationship between megastigmatrienone content in tobacco leaves and soil physico-chemical propertieswas analyzed by gray correlation analysis. The results showed that sand content and soil p H had the greatestinfluence on megastigmatrienone content, and the relationship between sand content in soil andmegastigmatrienone content in flue- cured tobacco leaves accorded with quadratic. The relevancy ofexchangeable calcium, exchangeable magnesium, available nitrogen, rapid available phosphorus and rapidavailable potassium with megastigmatrienone content was lesser.
