Post-freeze emergency measures: 1. Shake off the snow. The snow on the canopy must be shaken off or beaten with a long stick to prevent the snow from breaking the branches. 2. Irrigate in time. After the tree has lost water after freezing, the roots and trees need water, so they should be irrigated and watered in a timely manner. 3. Trim in time. After thawing, timely pruning of injured tree branches was performed to remove frostbite and snow-clad leaves. 4. Prevent diseases, spray foliar fertilizer. After frost damage, the resistance of fruit trees declines, pesticides should be sprayed to prevent diseases, and foliar fertilizers are combined with disease prevention to supplement crop nutrients, such as 0.3% potassium dihydrogen phosphate, urea, etc., to enhance plant resistance and promote growth. .
