Answer: In the winter cold season, 20-25 cm thick soil layer can be cultivated around the fruit trees to protect the trunks and remove the soil from the fruit trees to prevent the root system from being exposed to frost damage. In early spring, when the temperature rises, the soil is removed twice. The first time it is halved, and the second time it is completely removed. When it snows, shake the snow on the trees in time, and do not use sticks to knock down the snow, damage the branches, cause wounds and reduce the cold resistance. Spraying plant growth regulators can also prevent freezing. It can increase the metabolic capacity of the tree in the winter, regulate tree growth, and promote rooting.
