| 摘 要： | 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值的影响较大;烟叶铁含量为71.40～1 861.64 mg/kg,与土壤有效铁含量相关性不显著(r=?0.081),受有机质含量的影响较大;烟叶锰含量为13.73～1 020.22 mg/kg,与土壤有效锰含量呈极显著相关(r=0.258),受土壤有效态锰含量、海拔高度、土壤pH值的影响较大;烟叶硼含量为0.58～75.17 mg/kg,与土壤有效硼含量相关性不显著(r=?0.047),受海拔高度和有机质含量的影响较大。 |

| Abstract: | 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 contents of these trace elements in tobacco were all rich in tobacco,and the content of Cu in tobacco,which were 0.12–62.99 mg/kg,showed no significant correlation with Cu in soil(r=0.056) and was influenced by altitude and organic matter much more;the content of Zn in tobacco,which were 12.62–162.26 mg/kg,was very significantly correlated to available Zn in soil(r=0.084) and influenced by soil available Zn content and pH value much more;the content of Fe in tobacco,which were 71.40–1 861.64 mg/kg,showed no significant correlation with Fe in soil(r=?0.081) and was influenced by organic matter much more;the content of Mn in tobacco,which were 13.73–1 020.22 mg/kg,was significantly correlated to available Mn in soil(r=0.258) and influenced by soil available Mn and altitude pH value much more;the content of B in tobacco,which were 0.58–75.17 mg/kg,showed no significant correlation with B in soil(r=?0.047) and was influenced by altitude and organic matter much more. |
