Answer: You can cut off the injured branches before germination, and use 3 ~ 5 Baumedus stone sulfur mixture to coat the cuts, scrape off the necrotic tissue in the affected parts of the branches, and apply healing agents to increase the healing ability and restore growth early. In addition, the prevention and control of diseases and insect pests must be strengthened, because after the tree body is damaged by freezing, many diseases are often induced, and the control of diseases and insect pests must be strengthened from the young fruit stage. In late March, spray 1: 2: 200 times Bordeaux solution. After sprout, spray with protective agents such as zinc. Insect pests mainly control early aphids, and strictly control the harm of pests and diseases to promote early recovery of the tree.
