摘要： 采集了城关、松柏、桃川、允山、夏层铺5个植烟乡镇的104个土壤样品，研究了江永植烟土壤有效锰含量及其影响因素，为改良江永植烟土壤和烟区的可持续发展提供理论依据。研究结果表明：江永县植烟土壤有效锰含量适中，均值为19.56 mg/kg，变幅为3.80~93.80 mg/kg，变异系数达到93.30%，有效锰含量处于适宜范围的样本比例为49.04%。土壤有效态锰含量会随pH、有机质、全磷、全氮含量升高而降低。4个影响因素pH、有机质、全磷、全氮中，尤以有机质含量对土壤有效锰含量影响最大。

Abstract: 104 tobacco soil samples were collected from Chengguan, Songbai, Taochuang, Yunshan and Xiacengpu to study the the content of effective Mn in soil and its influencing factors, in order to provide theoretical basis for the improvement of Jiangyong tobacco soil and the sustainable development of tobacco industry. The results showed that: the content of effective Mn in Jiangyong tobacco soil was moderate, the average value was 19.56 mg/kg, ranged from 3.80 to 93.80 mg/kg, and the variable coefficient was 93.30%, the proportion of effective Mn in appropriate range was 49.04%. The content of available Mn in soil decreased with the increase of soil pH, organic matter, total phosphorus and total nitrogen content, and organic matter content had the greatest influence on the content of effective Mn.
