摘　　要：采用砂培盆栽实验,研究了油菜苗期硒对铅吸收的抑制作用。结果表明,硒对铅在植物体内的吸收具有抑制作用,且随着硒处理质量浓度的增大,油菜茎叶及根系吸收铅的能力下降。The inhibition action of selenium to lead in rapeseed seedling stage was studied using sand pot culture. The results show that there exists an inhibition action on absorbing of selenium to lead in plant. And as selenium content in the above, the abilities of absorbing lead on ground parts and root of rapeseed were fallen.
