In the winter, if the cherry tree bark layer suffers from vertical cracks, it is easy to cause pests and diseases, so it is important to do a good job of protecting the tree against cold. The trunk was tied to the grass before the advent of freezing, and 10 cm thick hay was tied to the trunk to prevent frostbite. The tree tray is kept warm, and the whole tree plate is covered with mulch, crop straw or weed, or the soil around the neck is 5 to 10 cm in thickness, and the soil layer is removed when germinating. In the winter irrigation, when the local surface water appears to be frozen overnight, the frozen water is filled and the temperature below 0° C. can be maintained below the ice level in winter to protect the roots of fruit trees from frost damage.
