摘  要：
为研究烟稻复种连作对土壤有效中、微量元素含量和烟叶中对应元素含量的影响效应,采取烟田定位检测和回归分析方法进行试验。结果表明,0~23年烟稻复种连作研究范围内,土壤和烟叶中的硫含量呈逐步积累趋势,土壤中其它9种中、微量元素有效铁、锰、铜、锌、硼、钼、水溶性氯、交换性钙、镁含量在复种连作10~15年后,呈不同程度的下降趋势,烟叶中对应的9种中、微量元素含量或呈直接下降趋势或复种连作10年后呈下降趋势,以上变化不利于烤烟良好品质的形成。土壤有效硼、钼、硫、钙、镁含量与烟叶中对应元素含量达到了极显著或显著的正相关关系,其它元素相关性不显著。

摘  要：
The effect of continuous and multiple cropping of tobacco-rice on soil available medium & trace elements and the corresponding elements in tobacco leaves was carried out in tobacco field. The results indicated that during 0 ~ 23 years of continuous and multiple tobacco-rice cropping,the sulfur content in soil and tobacco leaf increased gradually; the soil available nutrients of other 9 kinds' medium & trace elements showed different degree'downward trend after 10 ~ 15 years of continuous and multiple tobacco-rice cropping,meanwhile these corresponding 9 kinds of nutrient elements in tobacco leaves showed a downward trend directly or after 10 years of continuous and multiple cropping. The above changes were disadvantaged to the formation of good quality of flue-cured tobacco. The correlation between soil available boron,molybdenum, sulfur,calcium and magnesium and the corresponding elements in flue-cured tobacco leaves very significantly or significantly positive,other elements had no significant correlation.
