In view of the prevention and control of brown root disease of trees on the campus, which poses a threat to public safety, a health inspection and risk assessment of trees near the main roads, sidewalks and parking lots of the campus were carried out in March 2020. 26 trees were confirmed to be suffering from brown root disease. For the first seven, 46 trees are adjacent to brown root disease, and the 2021 project budget is actively compiled for the prevention and control of brown root disease of trees.
