向日葵、油菜对镉胁迫反应及对镉污染土地修复作用研究进展

摘要

Soil is contaminating because more and more heavy metal enter into soil as the increasing of human activities. Among the heavy metal,Cd is the most toxic to human body.The harnessing of the soil polluted by cadmium became one of the most concerned issues by people.Compared with different regulation methods of soil heavy metal pollution,phytore-mediation is considered to be the best.This article summarized the research about the reaction of sunflower and rape under cadmium stress in recent years around the world.The phytoremdiation of sunflower and rape for the cadmium contaminated soil was overviewed.The research direction for the future was discussed.%随着人类活动的增加，越来越多的重金属进入土壤中造成土壤污染，其中镉是对人体毒害最强的，土壤镉污染治理已经成了人们最关心的问题之一。对比不同的土壤重金属污染治理的方法，植物修复被认为是最好的。总结了向日葵和油菜对镉胁迫的反应，以及它们对镉污染土地的修复作用，并对以后的研究方向进行了探讨。
