2011年对永州市53个种烟乡镇的629个植烟土壤的微量元素有效养分进行了取样调查和统计分析，结果表明：永州烟区植烟土壤有效铜、铁、氯含量丰富，极少缺乏；土壤有效锌、钼、锰部分缺乏，应适当补充；95％以上的土壤有效硼处于缺乏状态，应大范围补充。聚类分析将永州烟区植烟土壤微量元素含量划分为4大特征区域，应根据土壤养分分布特征，合理施用微量元素肥料。
2011年對永州市53箇種煙鄉鎮的629箇植煙土壤的微量元素有效養分進行瞭取樣調查和統計分析，結果錶明：永州煙區植煙土壤有效銅、鐵、氯含量豐富，極少缺乏；土壤有效鋅、鉬、錳部分缺乏，應適噹補充；95％以上的土壤有效硼處于缺乏狀態，應大範圍補充。聚類分析將永州煙區植煙土壤微量元素含量劃分為4大特徵區域，應根據土壤養分分佈特徵，閤理施用微量元素肥料。

The contents of available trace elements of 629 soil samples collected from 53 tobacco -growing towns of Yong-zhou city were investigated and statistically analyzed in 2011.The results showed that the contents of available Cu,Fe and Cl were rich in tobacco -growing soil of Yongzhou.The contents of available Zn,Mo and Mn were partly lack,and which should be appropriately complemented.Available B in 95% of soil samples was deficiency in the soil,and which should be widely complemented to tobacco -growing soil.Based on the content of trace elements,tobacco -growing soil of Yong-zhou was clustered into 4 groups.Trace element fertilizer should be applied properly according to the nutrient distribution properties.
