As the saying goes: “It is necessary to eat pears and scrape the bark.†The scraping of fruit trees is an important measure for the management of orchards in the winter. It not only helps to increase tree vigor, prevents premature degeneration of the trees, but also eliminates wintering in the cracks in the barks. The pathogens and pests will reduce the base number for overwintering and control or reduce the occurrence and damage of some diseases and insect pests in the coming year, thus receiving the anti-control effect of “do not apply pesticides and win pesticidesâ€. The following four points should be paid attention to when peeling the pear tree in winter: First, scraping the skin. Pear trees more than 10 years old, the main branch, dry cortex will occur in varying degrees of cracks, it should be scraping. The second is scraping strength. The younger ones should be scraped and the old ones should be heavily scraped. Scrape must be deep and thorough. But the movement should be light and prevent scratching the tender skin. The third is the scraping time. When the pear tree enters the wintering period, it can last until the early spring pears sprout. Fourth, care after shaving. After scraping the skin, the dander should be collected and burned in time. The main branch should be promptly coated with whitening agent such as 10 kg of lime, 2 kg of salt, 1 kg of sulfur powder, 0.1 kg of animal or vegetable oil, and 20 kg of water. For pear trees with rot and blight disease, apply Fumei arsenic or lime sulphur to prevent and cure the skin in winter.
