Fruit tree scraping "five measures"
Curing old fruit trees is an effective measure to eradicate pests and rejuvenate the tree. This is a good measure. Pests can be reduced by 70% to 80% over the winter, pathogens are reduced by more than 80%, and the use of drugs is reduced by 1 or 2 times in the growing season. Save money and increase efficiency. However, there are many problems in the scraping of bark by fruit growers. Five reforms are now proposed. Early in the evening, most people think that the sooner the scrapings go from leaf to flowering, the better. It's actually wrong, because it takes several months before the leaves fall to flowering. The early scrapings on the one hand are exposed by the young tissue and the wind blows. Sun exposure, loss of moisture, on the other hand scraping off the old skin, the equivalent of a layer of clothes off people, the ability to significantly reduce the cold, so it should be before the pest that the insects before scraping the skin as well. The depth of change is shallow. A considerable number of fruit growers are too deep and heavy to shave, so that fresh and disease-free protective tissues are severely damaged and affect the normal growth of the tree. Therefore, it is appropriate to just remove the diseased body and knock off the skin, that is, the tree is white. The tree is green and the disease-free body does not scratch. Change the thickness to fine, do not scrape only the main disease, the main branch on the epiphyseal body, for more than 1 year old twigs should also be carefully observed, do not miss a small tumor, because mung bean size tumors can produce hundreds of millions of colonies After the scraping of the entire tree, it must be checked again and again to achieve complete and complete objectives. Change the belt to be buried. When scraping the skin, pay attention to spreading plastic paper or chemical fertilizer bags under the trees. Collect the skin disease body at the same time. Do not bring it out of the orchard or burn it, because the bacteria brought to the garden can continue to spread along with the water flow. Burning and wasting nutrients is the best way to dig more than 30 centimeters deep in the orchard and bury the fallen leaves of the tree. After rot, it is a better nutrient. Change old to new, scrape skin should not use high residual, highly pathogenic Fumei arsenic coating or spray, can be used pollution-free biological pesticides 5 times chlorhexidine, or use pollution-free chemical synthesis of gum tree, biofilm, etc. The bactericidal protection of the brush spray, especially the gum tree, the biofilm is applied to the tree to form a film, the bacteria is not easy to invade and infect, and the moisture of the tree is not easy to dissipate.
