摘要 在我国加强重视生态农业的宏观背景下,阐述了我国农田土壤重金属污染的现状,以及对作物生长发育、产量、品质和对人体健康的影响,分析了农田土壤重金属污染形成的原因,介绍了当前我国重金属污染农田土壤物理、化学、生物修复技术和重金属低富集品种筛选应用、种植结构调整、农艺措施调控等重金属污染农田土壤安全生产技术的研究进展。为我国修复重金属污染农田土壤,实现重金属污染土壤安全农业生产提供了理论和现实技术参考。最后,在我国重金属污染农田土壤修复及安全利用技术研究现状的基础上,对今后的研究思路和方法提出了建议。 The paper described the situation of farmland soil heavy metal pollution in China under the macro-background of paying great attention to ecological agriculture and the effects of farmland soil heavy metal pollution on the growth,yield and quality of the crops and people's health, as well as the causes of the pollution. The research development for the soil remediation and the safety production was also presented,including physical treatment, chemical remediation, bioremediation, selection and breeding of cultivars that accumulate lower levels of heavy metals, adjustment of cropping industrial structure and agronomic regulation, etc. The results provided a theoretical basis and a real reference for the soil remediation and the safety production. Lastly, some suggestion was brought forward for research guideline and methods of farmland soil heavy metal pollution abatement in future according to present condition.
