In the dormant season of fruit trees, scraping off the rough old bark on the tree body can eliminate the source of diseases and insects that overwintered on it, stimulate the bark to renew and grow, and is conducive to tree development. Saplings of fruit trees should be conducted from December to February of the following year. The climate is cold or the shady areas in the mountains are advancing from start of spring to convulsions. Places with warmer climates can be scraped as early as possible. Sapling of fruit trees differs depending on the species, size, and thickness of the bark. Apples, pears, dates, etc., which are generally more than 10 years old, can be shaved. For example, the rough branches of the stems are also shaved. Peaches, apricots, and other stone fruit trees and persimmon trees should not be shaved, and brushing of the bark can be used. The skin of the apple tree is thin and should be lightly shaved and lightly shaved. The thick skin of the pear tree should be deep scratched. The fruit trees were shaved to see red endothelium. Scrape the skin thoroughly and smooth it to leave no gaps. Before scraping the bark, put a plastic sheet around the trunk so that the scraped bark and pests can be burned or buried deeply. After the fruit trees are shaved, whitening protection should be applied. (Source: China Green Times Meng Dehui)
