摘要：

摘要：【目的】米易县是攀枝花市烟叶的重要产区，为了解该区植烟土壤有效态微量元素含量特征；【方法】对米易县12 个产烟乡镇345 个植烟土壤样本中有效态微量元素进行了测定分析统计；【结果】米易县植烟土壤有效铁和有效锰平均含量达到146.91 mg/kg 和 69.80 mg/kg，含量极丰富；有效铜平均含量为3.49mg/kg，含量丰富；有效锌、有效钼平均含量为1.53mg/kg和0.28mg/kg，含量中等；有效硼平均含量为 0.09 mg/kg，含量极低；【结论】几种微量元素在不同海拔高度、不同土壤类型和不同乡镇间都存在不同程度的差异，需要合理补充相应的微量元素肥料。

Abstract:

【Objective】Miyi is the important region of the tobacco of Panzhihua,in order to find out Miyi tobacco soil microelements content characteristics;【Method】 Effective state Microelements were determinationed in 12 townships and 345 soil samples in Miyi ;【Results】The average content of available Fe、Mn is 146.91mg/kg and 69.80mg/kg in tobacco soil in Miyi, the content is extremely rich；available Cu’s average content is 3.49mg/kg which has a rich content; the average content of available Zn ,Mo is 1.53mg/kg and 0.28mg/kg, the content is medium and the average content of available Cu is 0.09mg/kg which content is extremely low; 【Conclusion】There are differences between in these kinds of microelements in different altitude, different soil types and different towns, the corresponding trace elements fertilizer should be added reasonablely.
