Winter has many benefits for fruit trees
Pears, jujubes, apricots, apples, and other fruit trees are prone to produce rough skin, and as the tree ages, the bark grows thicker and gets older, loses its elasticity and stretchability, hinders the transport of water and nutrients, and affects the thickening of wood. Weaken the tree vigor and make the tree premature. The coarse groove gap is also a place where wintering of pests and pathogen spores occurs. Therefore, the rough skin will be scraped in winter to remove the pests and diseases, but also to promote the growth of fruit trees and increase production.
The measures for scraping fruit trees are applicable to adult trees over 10 years old. They are carried out at the end of winter and early spring to scrape off the rough skin, split skin, and the residual skin at the branches and branches of the trunk and main branches. If you do not see white, it is advisable to shave the stronger tree vigor and shave the weaker one. After smearing, oily ointment “wound and anti-corrosion film†should be applied in time to disinfect and sterilize. The tough and soft film formed should adhere to the xylem, prevent rain pollution and dry cracks and frostbite, in order to control the damage and promote healing. Do not scrape the skin prematurely, otherwise the tree nutrients will be lost and the fruit trees will be safely overwintered. The skin is shaved once every 2 to 3 years.
For lesions such as rot and ulcer disease, use a razor blade to gently scribe on the affected skin (vibration can spoil the rot of spores), and apply a brush to the "General Tree Guard" to quickly make the diseased skin dry and stained with dead spores. The diseased skin began to fall off. Scraps and parasites are collected, burned or buried deeply.
