Fruit trees scratching pests

Adult trees grow thicker with age and grow thicker year by year, giving rise to chapped and split skin. This is a natural phenomenon of tree decline. The rough skin of fruit trees impedes the transportation and metabolism of water and nutrients, and also affects the coarse growth of trunks. At the same time, the skins and cracks are overwintering sites for many kinds of pests and bacteria. Scratching the old skin of the fruit tree can not only slow down the aging and prolong the full fruit period, but also effectively eliminate overwintering eggs, maggots, larvae, and adults of pests such as leaf roller moth, red spider, pear caterpillar, pear borer, and pear hibiscus. The spores of rot, soft-streak, and other pathogens greatly reduce the occurrence of pests and diseases and promote fruit yield and quality. Now introduce the scraping technology points for reference. 1. Scrape objects Pears, peaches, plums, grape chestnuts, walnuts, apples, plums and other fruit trees that are prone to produce rough skin, and adult trees more than 10 years old are necessary to scrape skin. 2. Skin scraping time In order to ensure that the fruit tree branches are not damaged by frostbite, they can also achieve the goal of eliminating pests, germs, and promoting the fruitful growth of fruit trees. The scraping of skin should be carried out from late winter to early spring, that is, temperature begins to rise, pests and When germs have not yet begun to move. Do not scrape the skin prematurely, otherwise the tree nutrients will be lost and the fruit trees will be safely overwintered. Usually 2-3 years, scraping the skin once. 3, scraping skin deep scraping skin can only scrape off the trunk and the main branch of the appearance of the complete corked rough skin, split skin and cut and branch fork at the residual skin, but also scraping rot disease and round ring disease and other diseases spot. It is advisable to shave the skin to a depth that is not visible to red, and to avoid damage to the endothelial layer. The thick skin of the pear tree can be properly scraped deeper, and the stone fruit trees such as peach apricot are lighter. Those who have stronger tree vigor can shave more. Those with weaker vigor should shave more. 4, scrape after the white skin scraping after the application of white paint again to kill pests and germs, but also can reduce the incidence of sunburn. The ratio of white paint was: water: quicklime: lime sulfur stock solution: table salt: fat = 40:10:2:2:0.3. Liberate the lime, pour the oil, add water into the lime milk, then add the sulfur mixture and salt. 5. Other matters When scraping the skin, a plastic film should be placed under the canopy in order to collect the scraped dandruff and the body of the insect and burn it or deepen it. The white paint is applied in non-metallic containers, and should not be filled with metal containers to avoid chemical reactions. White paint should be used with the match and must not be stored for a long time. The above-mentioned scraping technology is also suitable for scraping operations of forest seed orchards and mother tree mother trees.
