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
