摘要

采用土壤盆栽试验

以十字花科、锦葵科、菊科共十种植物为研究材料

在100mg/kg铀浓度土壤环境中培养55d后收割

采用ICP-AES分析方法测定植物地上部分和根部铀的含量。结果表明:试验的十种植物中

特选榨菜地上部分铀含量最高（1115mg/kg干重）

艾蒿地上部分铀提取量最大（1113μg/盆）;泡青菜和特选榨菜地上部分铀含量高于根部

迁移系数、生物富集系数均大于1

这两种植物地上部分均有较高的铀提取量

适合推荐作为铀超积累植物进行植物修复。

Abstract

A pot experiment was conducted to investigate the possibility for phytoremediation of U-contaminated soils. Ten plants of cruciferae (8 species)

malvaceae or compesitae were planted for 55 days in the U-contaminated soils (100 mg·kg-1). The samples were analyzed using an inductively-coupled plasma atomic emission spectrometer (ICP-AES). The results showed that U concentration was the highest in shoots of Chinese mustard (var.Texuanzhacai

1115 mg·kg-1)

the highest U removal from U-contaminated soils to plants occurred in the shoots of Artemisia argyi (1113 μg per pot). For the Chinese mustard (var.Paoqingcai

var.Texuanzhacai)

uranium concentration in shoots was higher than in roots

and bioaccumulation factors (BFs) and transfer factors (TFs) were more than one. They showed better suitability for phytoremediation of U than other plants due to their high U accumulation in the aboveground tissues.
