| 摘 要： | 对湖北省恩施市几个主要产烟区的烟地土壤的调查分析和对烤烟盆栽试验结果的分析表明，烟地土壤含硒量因土壤母质而异，并与土壤有机碳含量呈正相关，其分布随土壤深度增加而减少；烤烟团棵期含硒量随土壤含硒量和土壤施硒量的增加而增加，并呈现出地下部分大于地上部分的分布规律。

| Abstract: | The results of analyzing tobacco soil in Enshi show that Se- content in bobacco soil is related with soil rocks and possitively correlated with organic carbon content in soil, but its distribution decreases as the soil deepens. The results of pot culture experiment on flue - cured tobacco prove that Se- content of Flue - cured tobacco in tuanke stage increases with soil Se- content and is possitively correlated with soil Se supplement. But the distribution of Se- content under ground parts is higher than that of superficial ones. |
