畜禽粪便有机肥源重金属在土壤—蔬菜系统中累积、迁移规律的研究进展

Research Progress on Heavy Metal Accumulation and Migration of Livestock Dung Organic Fertilizer in Soil-Vegetable System

综述了畜禽粪便有机肥源重金属在土壤—蔬菜系统中的累积、迁移规律。介绍了有机肥源重金属对农业用地的污染,尤其是畜禽粪便有机肥导致的蔬菜种植用地重金属污染状况,总结了近年来施用畜禽粪便有机肥的农业用地重金属累积规律以及土壤—蔬菜系统重金属吸收迁移规律,并对今后相关研究工作进行了展望。

This pap er summarized the laws of heavy metal accumulation and migration of livestock dung organic fertilizer in soil-vegetable system and briefly introduced the organic fertilizer heavy metal pollution in agriculture land, especially in vegetable planting land caused by livestock dung organic fertilizer. The heavy metal accumulation and migration laws in agricultural land were reviewed in the application of livestock dung organic fertilizer, and heavy metal absorption and transformation laws in soil-vegetable system were summarized in recent years, consequently. The future research works were prospected.
