In winter, 20~25 cm thick soil layers can be cultivated around newly planted fruit trees to protect the trunk. The soil should be taken away from the fruit trees to prevent the root system from being exposed to frost and the soil should be dry and fine. When the temperature rises in early spring, the earth should be removed in time, half removed for the first time and completely removed the second time. It can be used to cover the canopy of straw, film, etc., and use straw to wrap up the trunk. For fruit trees growing on a loquat, the branches are bundled into bundles and slowly pressed back to the ground, covered with soil and cold, with a thickness of about 20 cm. When snow falls, it is necessary to shake the snow off the tree in time to avoid breaking the branches after snowfall. Do not use bamboo sticks to beat the snow, damage the branches and cause wounds and reduce the cold resistance. Spraying plant growth regulators can also prevent freezing. Such as the use of wide-growth hormone 802 or love more to spray fruit trees, can increase the tree's metabolic capacity in the winter, regulate tree growth, promote rooting, improve fruit frost resistance. After the fruit trees are frozen, the thin organic manure after decomposing should be chased in early spring and the dead shoots or shoots should be cut off after germination so that the fruit trees can quickly restore the tree vigor.
