摘要
在我国的重金属土壤污染中,镉(Cd)污染是危害性最大的,因此有关植物对镉胁迫的耐受性机制一直是人们研究的热点,其中多数研究主要是针对单一Cd胁迫进行的,但是在自然环境下Cd通常与铜(Cu)、锌(Zn)等其它重金属共同富集在土壤中,给重金属污染修复带来很大困难。本文主要从Cd污染的危害、植物自身抗性及Cd与其它金属元素的相互作用等方面做出了简要综述,对重金属土壤污染的研究提出了发展和展望。
The heavy metal cadmium (Cd) enriched in soil is one of the most harmful pollution issues in the whole world. The most of the research related to plant response to Cd stress mainly focus on Cd stress alone, ignoring the question that multiple kinds of heavy metals including Copper (Cu), Zinc (Zn) frequently combined with Cd in soil in the natural environment. It has brought great difficulties in governance. Here, we combine the recent research reports from the aspect of Cd harm, the resistance of plant and the interaction with other metal elements under Cd stress to make a brief summary. Then, the development and prospect in heavy metal contamination of soil research were proposed.
