摘    要:调查了恩施州植烟土壤及烟叶硒含量状况。结果表明:(1)恩施州植烟土壤硒含量平均为0.661 mg/kg,从土壤总硒水平来看,恩施土壤属于富硒土壤。烟叶硒含量平均为0.216 mg/kg,并表现为B2F>C3F>X2F,高于我国其他烟区。(2)恩施土壤硒的垂直地理分布特性明显,即随海拔高度的升高而极显著地增加;土壤硒含量与土壤中有机质、碱解氮、速效磷、速效钾等大量元素具有极显著正相关,而与pH的相关性没有达到显著水平。当土壤等级为足硒和富硒土壤时,土壤中主要养分含量处于烟叶生长所需的适宜范围内。(3)在相对较高的硒含量土壤中,烟叶对硒的吸收累积强于低硒土壤。8个植烟县(市)土壤和烟叶硒含量的相关性均为正相关。

关 键 词:恩施  烟区    土壤  烟草

Abstract:The status of selenium contents in soil and flue-cured tobacco in Enshi tobacco-growing areas were analyzed.The results indicated that:(1) The average content of selenium in soil in Enshi tobacco-growing areas was 0.661 mg/kg and could be defined as selenium-rich.The average content of selenium in flue-cured tobacco leaves was 0.216 mg/kg and showed the trend of B2F > C3F > X2F.The contents of selenium in soil and tobacco leaves in Enshi were higher than other areas.(2) The content of selenium in soil in En...
