Protection Construction Technology of Ancient Litchi Chinensis under Adverse Environment

Ancient trees protection technology under adverse environment plays a very important part in tree conservation and transplant protection in urban renewal projects. In order to develop the protection effects, researchers using complex technologies including growth status dynamic monitoring, resist typhoon trimming and shaping, root maintenance, the result shows that trimming operation decreased leaf area, which helps improve the resistance of typhoon. The overall technology can promote the effective recovery of tree vigor, which is conducive to the promotion of full crown migration work.
