The invention relates to the technical field of ancient tree maintenance and discloses a dry-rot tree hole cleaning composition for ancient tree maintenance and an application thereof. The key to repairing a tree hole is how to prevent the tree hole from further decaying. The prepared hydroxyl-containing quaternary ammonium salt long-chain siloxane has an antibacterial quaternary ammonium salt structure, and the hydrophobic quaternary ammonium salt is introduced into a hydrophilic polyurethane molecular chain, which is beneficial to the preparation of a polyurethane foaming agent and exhibits good antibacterial durability. In addition, the tree hole also needs to be waterproofed, and the introduction of silicon-oxygen bonds not only promotes good compatibility with polyurethane, but also improves the water resistance of the material. At the same time, the tree hole also needs to effectively isolate harmful insects, and pyrazole compounds have extremely high activity and high-efficiency and low-toxic insect resistance. In addition, the modified polyurethane is added to a foaming agent for foaming, which can completely fill the tree hole part, ensuring the normal growth of the ancient tree while improving its ornamental value.
