采用经典统计学和地统计学方法,分析云南省陆良县植烟土壤及烟叶中铜、锌、铁、锰、硼5种微量元素的含量和空间分布特征及主要影响因素。结果表明:参照土壤微量元素丰缺标准,陆良县植烟区土壤有效铁含量（76.78 mg/kg）、有效锰含量（36.80 mg/kg）极高,有效铜含量（1.59 mg/kg）、有效锌含量（2.13 mg/kg）较高,有效硼含量（0.54 mg/kg）适中;烟叶中各微量元素含量都较为丰富,烟叶铜含量为0.12～62.99 mg/kg,与土壤有效铜含量相关性不显著（r=0.056）,受海拔高度和有机质含量的影响较大;烟叶锌含量为12.62～162.26 mg/kg,与土壤有效锌含量呈极显著相关（r=0.084）,受土壤有效态锌含量及土壤pH值...

The contents of trace elements （Cu, Zn, Fe, Mn, B） of tobacco and soil in Luliang were analyzed using the classical statistical methods. The result obtained according to the standard for rating the level of available trace elements in soil showed that in soil of Luliang, the contents of available Fe and Mn were 76.78 mg/kg and 36.80 mg/kg, respectively, which were very rich; the contents of available Cu and Zn were 1.59 mg/kg and 2.13 mg/kg, respectively, which were rich; and the content of available B was 0.54 mg/kg, which was moderate. The ...
