Returning to the earth in spring is the critical period for the rot of fruit trees in Chah. Fruit tree rot disease is a fruit tree disease with a wide range of occurrence, heavy damage, and great loss. In light cases, large branches and branchlets die; in severe cases, the whole tree of fruit trees dies and should cause fruit growers to attach great importance. According to the analysis, cold damage, sunburn, and extensive management are the causes of the disease. The year when large frost damage occurs is the year when rot occurs or begins to happen. In mountainous and sandy orchards, sunny branches are prone to sunburn, and rot is also prone to occur. Sloughing off the branches of trees due to rot disease is more prone to sunburn and aggravated rot disease. Freezing damage and sunburn weaken the tree vigor and increase bark necrotic tissue, creating conditions for the invasion and expansion of germs. In addition, in orchards with shallow topsoil and infertile lands, poor or low-lying drainage and heavy pests and diseases and excessive fruit orchards all cause serious disease. Strong tree potential Determine the reasonable load of fruit trees, according to the tree growth status and fertilization level, determine the appropriate amount of results, do not make the tree burden too heavy, to appropriate sparse fruit thinning, so that the results, long trees are correct. Strengthen water and fertilizer management, according to analysis, many of the more common phenomenon of fruit trees is the lack of fertilizer and water shortage, investment in fruit farmers. In fertilization, pay attention to increase organic fertilizer, pay attention to increase phosphate fertilizer, potassium fertilizer and trace element fertilizer. At the same time, do not apply too much partial nitrogen fertilizer, especially in the autumn fertilization avoid partial nitrogen fertilizer. To protect the leaves and promote root and timely control of the diseases and insect pests that cause early defoliation, such as apple leaf blight, early spotted deciduous disease, peach perforation, walnut anthrax and spider mites, aphids, various kinds of borers, leaf roller moth. Pay attention to the prevention and treatment of various root diseases, especially root cancer. We found that tree vigor was in time to check if nodules occurred. Once found, root nodules under the rhizome should be promptly removed to root the cancer. At the same time, it is necessary to add and protect amino acids to promote new roots and enhance absorption capacity. The second is to avoid and protect the wounds of fruit trees. Avoid, reduce the branches of wounds, and properly protect existing wounds and promote healing. Thorough control of trunk pests, such as Giardinus, Tianni and others. At the same time prevent freezing damage and daily burning. The sun-dried fruit tree trunks have a large temperature difference between day and night and are prone to frost damage. If there is no leaf cover on the sun surface in the summer, it is easy to get skin due to sun exposure. Effective measures The trunk is painted white to reduce the temperature difference between day and night, and the whitening is required after the leaves are fallen. The trunks are tied up with grass and covered with antifreeze. Pour frozen water before winter to reduce frost damage. To protect the wound, it is necessary to flatten the larger kerfs at the time of trimming, and then protect the wounds of fruit trees with healing agents. For diseased fruit trees, it is recommended to use medicinal control. One is to scrape off the curled bark and necrotic tissue before sprouting. The scraped dead bark and pruned sick branches should be brought out of the orchard in time for burning or deep burial, and then sprayed with 3-5 degree lime sulfur or Corruption rot. The second is that during the growing season, it is necessary to deal with lesions, especially in the summer. After scratching the diseased tissue, use 2% NINGNANXIN 100 times fluid to add wounds or spray spoiling rot, which is better for curing lesions. Effect.
