摘要:

受农用品投入、固体废弃物堆放、污水农灌及大气沉降等因素影响,导致农田土壤退化、农产品安全等问题愈发严峻,重金属污染通过食物链严重威胁人体健康,成为中国农业环境领域亟待解决的关键问题之一。针对中国农田重金属污染现状,从有机、无机钝化材料、土壤钝化健康技术出发,对农田土壤重金属污染健康修复技术进行深入梳理、分析,提出目前农田重金属土壤修复中存在的主要关键瓶颈问题,从有机、无机联合钝化、绿色农产品投入、土壤质量健康提升等方面进行展望发展趋势,为土壤重金属逆境的生态治理、农田废弃物循环利用及土壤健康可持续发展提供理论及技术依据。

Abstract:

Affected by factors such as input of agricultural materials, solid waste dumping, sewage irrigation and atmospheric deposition, problems such as farmland soil degradation and agricultural product safety are becoming more and more serious. Heavy metal pollution seriously threatens human health through the food chain and has become one of the key issues in the field of agricultural environment in China. According to the status quo of heavy metal pollution in farmland in China, from the perspective of the organic and inorganic passive materials and soil passivation health technology, we analyzed the health restoration technology of heavy metal pollution in farmland soil, and proposed the main key bottlenecks in the current soil remediation of heavy metals in farmland, and looked forward to the development trend from organic and inorganic combined with passivation, green agricultural input, and soil quality improvement, which could provide a theoretical and technical basis for ecological control of soil heavy metal stress, the recycling of farmland waste and sustainable development of soil health.

Key words: Farmland Heavy Metals, Passive Material, Soil Health, Ecological Restoration, Application Trend
