Abstract: As a worldwide harmful invasive plant, Eupatorium adenophorum has an adverse effects on agriculture, forestry, husbandry and even human health because of its strong adaptability, rapid diffusing speed and harmful substances. Therefore, how to effectively prevent, control and comprehensively utilize Eupatorium adenophorum has become a hot issue. Biochar is a carbon-rich solid material formed by pyrolysis and carbonization of organic substances under low or limited oxygen conditions. Due to its unique properties and potential value, it is widely used in agricultural soil amendment, environmental remediation and other fields. The pyrolysis of Eupatorium adenophorum to produce biochar not only reduces the production cost of biochar, but also protects the ecosystem and re-uses the waste efficiently. At present, although there are some studies on the preparation of biochar from Eupatorium adenophorum, the reports are relatively few, and the researches are scattered and conclusions are different from one to others. Therefore, it is necessary to review the current utilization status of Eupatorium adenophorum and the application potential of biochar. Based on the current research status of Eupatorium adenophorum in application, this paper analyzes the research value of the preparation of biochar from Eupatorium adenophorum and summarizes its application in environmental remediation and agricultural soil amendment, then puts forward the future research direction and prospect, with a aim to provide a reference for the coming researches.
Key words: Eupatorium adenophorum; biochar; environmental remediation; soil amendment
