| Abstract: | As a kind of high quality soil conditioner, biochar made the resources recycled and realized. It has huge application value and practical significance in the field of agriculture and ecology, thus universal attention by scholars both at home and abroad has focused on biochar in recent years. This paper reviewed the biochar effects on the soil heavy metal pollution repair, and from the effect of biochar on the improvement of soil aggregate micro domain environment cation exchange capacity, nutrients and organic matter, explored the effects of biochar to soil heavy metal pollution repair mechanism. The results showed that the biochar played a significant role in fixing and improving the form of soil heavy metal and the biological effectiveness. Suggestions and prospect for future research in this field were proposed in this paper, so as to provide a reference for biomass charcoal development. |
