报告题目：镉污染土壤的植物萃取及其强化修复技术 

报告摘要：

镉在生产活动中容易被作物吸收富集，不仅严重影响作物的产量和品质，甚至直接威胁人类健康。植物萃取修复能不断移走土壤重金属，降低重金属含量，在重金属污染土壤修复领域具有广阔的应用前景。本报告重点介绍课题组在该方向的研究进展，包括超积累植物萃取镉的机理探究，利用微生物、纳米材料强化植物萃取，以及中轻度镉污染土壤的边生产边修复技术研究。

TITLE：Phytoextraction and its enhancement remediation of cadmium contaminated soil

ABSTRACT：

Cadmium is easily absorbed and enriched by crops in production activities, which not only seriously affects the yield and quality of crops, but also directly threatens human health. Phytoextraction can continuously remove heavy metals from soil and reduce its content, which has a broad application in the field of heavy metal-contaminated soil remediation. This report will introduce the mechanism of cadmium extraction by hyperaccumulator, the technology of enhancing phytoextraction with microorganisms and nanomaterials, and the simultaneous production and remediation of moderately cadmium- contaminated soil.
