摘　　要：为掌握烟区土壤化学性状特征,2015年对永州市79个种烟乡镇689个植烟土壤取样调查和统计分析。结果表明,烟区土壤pH偏高,土壤有机质和阳离子交换量(CEC)丰富,分别有92.6%的土壤有机质和91.6%的CEC处于中等级别以上水平,植烟土壤肥力水平较高。土壤pH、有机质和CEC均存在正相关关系。通过聚类分析将烟区划分为2大特征区域,因地制宜,合理施肥及土壤保育。To understand the chemical characteristics of tobacco-growing soil in Yongzhou,689 tobaccogrowing soil samples from 79 tobacco-planting towns in Yongzhou of Hunan were investigated and analyzed in2015.The results showed that the collected soil samples had the characteristics of high pH and were abundant in content of soil organic matter and cation exchange capacity,and up to 92.6%and 91.6%of the soil samples were above medium level respectively in organic matter and CEC.Tobacco-growing soil had high soil fertility,and there was a positive correlation between the soil pH,organic matter and cation exchange capacity.The results of cluster analysis suggested that tobacco planting area in Yongzhou could be divided into two different characteristic regions,and measures of rational fertilization and soil conservation accorded with local conditions should be considered.
