Answer: The method of direct defense against freezing damage to fruit trees is more effective. At present, most of the physical methods adopted by fruit growers include: covering crop stalks, leaves, etc. between the rows of fruit trees, which can both protect the hoe and increase the temperature of the ground; the orchard covers the grass and applies grass and frost protection within a diameter of 1 meter around the fruit trees; Before the winter plowing, 15 cm of soil was cultivated on the fruit trees. Before the arrival of the winter solstice, the stems were tied with straw ropes, the main branches, or the trunk was tied with grass. After the heavy snow, the trees were shaken off the snow.
