| 中文摘要: |
| 通过对渝东南烟区植烟土壤及烟叶成分进行分析，明确土壤pH值对渝东南烟区烟叶质量风格的影响。以渝东南典型烟区彭水、武隆两县149份土壤样品及其对应的烤后中部烟叶样品为材料，分别对植烟土壤pH、中部烟叶全钾、全磷、全氯、B、Mn、Fe、Cu、Ni、As等元素含量分布特性及相互关系进行研究。结果表明：（1）彭水、武隆两县植烟土壤以酸性土壤（4.5 |

| To assess the influence of soil pH on tobacco quality in southeast Chongqing, the soil samples andcomposition of tobacco leaves were analyzed. Taking 149 soil samples and the corresponding 149 flue -cured middle tobacco leaf samples from typicality smoke generation countries in southeast Chongqing, Pengshui and Wulong counties as materials, the distributive characteristics and relationship soil pH value and the contents of 9 elements (total K, total Cl, total P, B, Mn, Ni, Cu, As, Fe) in middle tobacco leaves were analyzed. The results indicated that: (1) the tobacco planting soil of Pengshui and Wulong counties was mainly acid soil (4.5 |
