1. Trunk Wrapping and Wind and Coldproof Canopies: Wrap tree trunks with straw rope, non-woven fabric, or other insulating materials to reduce direct exposure to cold winds, and set up temporary windbreak canopies around the trunks.

2. Root Soil Addition: After frost damage occurs, the root system can be protected by increasing the thickness of the soil around the roots, and then address the issue once the spring temperatures stabilize.

3. Apply anti-freeze agent: Spray the anti-freeze agent once the temperature rises above 5°C to enhance the trees' frost resistance and prevent further freezing damage.

4. Strengthening Treatment: Prior to the temperature rise and the start of plant sprouting, conduct a strengthening treatment by applying organic fertilizers and trace element fertilizers to promote the recovery of tree growth.

5. Pruning and Wound Treatment: For frozen branches and trunk wounds, perform appropriate pruning and promptly apply disinfectants and healing agents to promote wound healing and prevent diseases.

6. Soil Management and Root Care: After thawing, loosen the soil around the trees for better aeration, apply mycorrhizal fertilizer to increase ground temperature, promote root growth, and strengthen the tree's vigor.
