Soil is an indispensable and important part of human production and life, and biochar, as an important form of utilization of biomass energy, can be widely used in soil conditioning and crop conditioning. Currently, a systematic framework for studying biochar's ecological impact on soil is still required. This paper briefly introduces the basic preparation method of biochar, structural characterization of biochar, and briefly describes its basic properties. By adsorbing pollutants with a high specific surface area and strong adsorption, biochar can be used to clean up heavy metal contamination in soil. It can also boost soil fertility by increasing enzyme activity and organic carbon content, as well as by reducing bulk weight and increasing cation exchange to increase soil fertility retention capacity. In addition the moderate addition of biochar can also play a positive role in crop conditioning to a certain extent. The purpose of this paper is to summarize the basic theories and research related to the study of the ecological effects of biochar in soil by introducing the typical preparation methods and basic properties of biochar, so as to facilitate the subsequent further research.
