Based on the practical experience of ancient tree protection and restoration in Ningguo City,Anhui Province,this paper analyzed the current growth situation of the ancient tree in the local area,summarized the commonly used techniques for ancient tree rejuvenation and restoration,and selected three ancient tree restoration projects in Pistacia chinensis(with the ancient tree identification number 34188120234),Torreya grandis(with the ancient tree identification number 34188120225),and Torreya grandis(with the ancient tree identification number 34188120174)as typical cases to explore the practical application of restoration techniques in the local ancient tree management.The research area has been continuously promoting the rejuvenation and restoration of ancient trees,and regularly conducting safety inspections and rectifications for tree structures.The existing management system is relatively complete,but a small number of ancient trees face problems such as structural deterioration of the tree bodies,restricted natural environment,and decreased soil fertility.The ancient tree protection and restoration techniques include repairing tree holes,managing growth space,pruning and reinforcement,supplementing soil nutrients,and controlling pests and diseases.The ancient trees at three sites exhibit issues including trunk cavities,close proximity to small cement-brick structures,and excessive dead branches.Through the implementation of tree cavity anti-corrosion repair,comprehensive environmental improvement around the trees,and tree pruning to reduce the load,the growth conditions of the ancient trees have been effectively improved,tree safety hazards have been eliminated,and the tree vigor has been effectively restored and long-term protected.
