The Application of Invasive Plant-Derived Biochar in Controlling Plant Invasion by Removing its Allelochemicals

Invasive plants seriously threaten the natural ecosystem and human health due to their strong ecological adaptability, reproduction, and diffusion ability, so that the utilization and control of invasive plants have attracted much attention. Biochar is widely used in environmental and soil remediation owing to its high aromaticity and anti-degradation ability. However, the research on biochar prepared by invasive plants to adsorb their own allelochemicals is still scarce, which may limit the application of biochar in invasion prevention and control. In this paper, the application of invasive plant-derived biochar (IPB) and the adsorption effect and mechanism of IPB and its composites on organic and inorganic pollutants are reviewed, which may enhance our understanding for the utilization of invasive plants and the restoration of local plant communities.
