Scraping the old peeling bark of fruit trees is an effective measure to eliminate pests and rejuvenate the tree. This measure is done well. The pests can be reduced by 70% to 80% over the winter, the pathogens can be reduced by more than 80%, and the use of drugs in the growing season can be reduced by 1 to 2 times. Save cost and increase efficiency. However, there are many problems in the production of fruit farmers scraping the bark. Five changes are proposed to enhance the effect. Change from early to late. Most people think that the earlier the peeling from leaf fall to the time before flowering, the better. In fact, it is wrong because it takes several months before leaf fall to flowering. On the one hand, early peeling is due to the exposed young tissues and the wind blowing. Drying will lose moisture; on the other hand, after scraping off the old skin, it is equivalent to taking off a layer of clothing, and the cold resistance is significantly reduced. Therefore, it is better to scrape the skin before germination, that is, before the pests sting. To change the depth to shallow, people need to face the tree and bark. A considerable number of fruit farmers scrape too deeply and too hard, which will seriously damage the fresh and disease-free protective tissues and affect the normal growth of the tree. Therefore, the depth is just to scrape off the diseased body and touch off the peeled bark. Appropriate, that is, the big tree is white, the small tree is green, and the disease-free areas are not scraped. Change the thickness to fine. Don’t just scrape the stems and pieces of diseased skin on the main branches. Carefully observe the branchlets over 1 year old, and don’t let a small tumor, because a mung bean-sized tumor can produce hundreds of millions of colonies. After the whole tree is shaved, check it again and again to achieve the goal completely. When changing the belt to buried and scraped, pay attention to spread plastic paper or fertilizer bags under the tree. While collecting the warped skin disease bodies, do not bring them out of the orchard or burn them, because the bacteria can continue to spread with the water when they are brought to the orchard. Burning wastes nutrients. ****** is to dig a deep hole of more than 30 cm in the orchard and bury it with the fallen leaves of the tree. After decay, it will be a better nutrient for the fruit tree. After changing the old to new, it is not advisable to use the high-residue and high-infectious arsenic coating or spraying. You can use pollution-free biological pesticides 5 times the rot and clear or use pollution-free chemically synthesized plastics, biological films, etc. Spraying for sterilization protection, especially to protect the gum and biofilm to form a layer of film on the tree body, the germs are not easy to invade and spread, and the tree body water is not easy to lose.
