2011年对永州市50个种烟乡镇的629个植烟土壤样品的钙、镁、硫等有效养分进行了取样调查和统计分析。结果表明：永州烟区土壤有效硫、交换性钙含量丰富，极少缺乏；土壤交换性镁部分缺乏，应适量补充。利用聚类分析方法将永州烟区植烟土壤有效钙、镁、硫含量划分为2大特征区域，第1类硫、钙含量较高、镁中等，第2类硫、钙含量高，镁含量较高。

Soil available Ca,Mg,S nutrient contents status were investigated and determined in 629 soil samples which were collected from 50 tobacco growing towns in Yongzhou city in 2011.The results showed that the contents of available S and exchangeable Ca were rich,rarely lack.The content of exchangeable Mg was partly lack;it should be applied to soil prop-erly.The tobacco growing soils in Yongzhou area were classified into 2 types by systematic cluster analysis of soil available Ca,Mg,S.Fertilizer should be applied appropriately according to the nutrient category of tobacco growing soil.
