摘 要 对贵州省黔东南州具有代表性的194个植烟土样的全钼含量、pH值和89个烟叶样本的钼含量进行测定。结果表明：黔东南州植烟土壤全钼含量平均为2.32 mg/kg，烟叶钼含量平均为0.53 mg/kg，土壤全钼含量较为丰富，烟叶钼含量较为缺乏；土壤全钼量与烟叶钼含量呈正相关性，土壤pH与烟叶钼含量呈负相关性，但相关性均未达显著水平。针对黔东南州植烟土壤及烟叶钼含量低的区域，尚需开展进一步的研究与探讨。

Abstract Molybdenum content and related items in 194 representative tobacco-planting soil samples and 89 tobacco leaf samples from Qiandongnan State of Guizhou procince were analyzed.The results showed that the average Mo content in Tobacco-planting soils was 2.32 mg/kg， average Mo content in tobacco leaves was 0.53 mg/kg. Soil Mo contents were rich， and tobacco leaves Mo contents were deficiency....
