Once the disaster weather happens, it is necessary to clean up the disaster site in time. Concentrate on the harmless treatment of broken branches, non-reserved values and twisted branches of ancient trees. Trim the stubble on the tree and apply calluses and wound protectants.

Cong Cong pointed out that when restoring trees, the sprained main branches should be fixed with metal hoops immediately, and the wounds should be protected by applying calluses and sealants. Spraying 40% omethoate 1000 times or 1500 times imidacloprid solution, sealing and drying to prevent the second invasion of moths. When necessary, support or integral reinforcement with the trunk can be used to accelerate the healing of the main branch.

According to the biological characteristics of different tree species and the disaster situation, the crown should be trimmed according to local conditions. Shortening local branches to promote crown restoration. According to the damage degree of ancient trees, measures such as topdressing outside the roots, supplementing nutrition under trees and improving the growth environment of ancient trees were taken to restore the tree vigor.

"It is very important to prevent and control secondary stem borers after the ancient trees are affected by disasters." The cluster theory, such as Beijing, is mainly to control the harm of all kinds of bark beetles and Monochamus alternatus.
