摘要: 随着农田土壤重金属污染的日益严重,农作物品质和产量不断下降,并对人类的健康产生了巨大的危害。但不同地区的污染状况存在很大的差异。针对不同污染程度的农田采取不同的修复措施,不仅能够提高修复效率,还能节约成本。文章综述了重金属不同污染程度农田的有效治理方法,中轻度污染农田主要采取植物阻控-植物富集移除、土壤钝化-植物阻控、农艺措施强化等防治措施;重度污染农田主要采取植物阻控-高效钝化、植物富集-其他高效技术、物理修复等修复措施。现在对于不同重金属污染程度修复技术的研究还存在不足,今后还需系统地针对不同程度的重金属污染研究出具体可行的修复技术。

Abstract: With heavy metal pollution of farmland is more and more serious, crops’ quality and yield decline continuously and cause harm to the health of human beings. But pollution status of different regions has great differences. Taking different restoration measures in terms of different pollution levels of soil can not only improve repair efficiency, but also cut the cost. This paper expounds the effective prevention and remediation methods for farmland soil with different pollution levels. For the moderately and slightly polluted farmland, we mainly take prevention measures as planting resistance control-plant enrichment, passivation-plant resistance controlling and agronomic strengthening; for the heavily polluted farmland, we mainly take prevention measures as planting resistance control-efficient passivation, planting enrichment-other high efficiency technology, physical remediation etc. Now the study on remediation techniques for different levels of heavy metal pollution is still insufficient. We need to develop concrete and feasible remediation technology for different levels of heavy metal pollution systematically.
