The turbid fluid disease is an extremely common disease in the large cherry producing areas. At present, the cause of the disease is unknown and it is not easy to completely eradicate it. The plasticity of the plants results in weakening of the tree vigor, which affects the growth of the tree and the quality of the fruit, while it can cause dead branches and dead trees, which has a greater impact on the production of big cherries. First, the symptoms and the site of the disease 1. Cause. The cause of rubber flow in cherry trees is relatively complex. All factors that hinder the normal growth and development of the trees may cause fluidity. First, due to parasitic fungal and bacterial damage, such as dry rot, rot, and perforation can all cause fluidity. Second, pests, especially maggots, cause wound-induced fluid injections, such as giardia, Red neck cattle and so on. Third, root diseases can also cause fluids. Such as root cancer, root rot. Fourth, mechanical damage, overweight trimming, cutting kerfs, and freezing injury, sunburn, etc. can also cause fluidity. Fifth, the construction of the park is irrational. The heavy soil, poor ventilation, poor drainage, and excessive water accumulation in the park can cause physical obstacles to the tree body, and can also cause fluid flow. 2. Symptoms and site of onset. Most of the diseases occur in branches, trunks and branches of the main branches are more likely to occur. At the beginning, the disease was slightly expanded and gradually overflowed with soft, translucent gum. After the rain, the gum gradually became jelly-like, almost transparent, yellow-brown after losing water, dark brown when dry, and surface solidified. In severe cases, the bark dehiscent, which is full of glial, cortical necrosis, debilitating growth, yellowing of the leaf color and weakening of the tree vigor. The disease is located in the southern Liaoning region, which is the peak of two epidemics every year from May to June and from August to September. Second, strengthen orchard management. 1. Reasonably build gardens and improve soil. Big cherries are suitable for cultivation on sandy loam and loam soils, to strengthen soil, fertilizer, and water management, increase soil fertility, and increase tree vigor. They do not build gardens where soils are heavy, where ventilation is poor, and where drainage is inconvenient. 2. Reasonably trimmed. There should not be too much sparse branching, and it is not advisable to remove large branches. Avoid large cuts, cuts, cuts, and weakening of tree vigor. When the tree is disordered and non-evacuation is not possible, it is also necessary to gradually eliminate large branches in different years, and it is better to grasp timely and appropriate amounts. 3. Strengthen soil management. Cherry trees are not resistant to flooding, flood control during the rainy season, timely cultivating loose soil, and improving soil ventilation conditions. 4. Branches painted white. The trunks and branches of winter and spring were painted white, preventing sunburn and freezing. Whitening agent preparation methods: 6 kg of lime, sodium chloride 1-1.5 kg, 0.3 kg of soybean juice, water 20 kg. First, the high-quality lime was hydrolyzed and unzipped, and then soybean juice and sodium chloride were added, and the mixture was stirred into a paste. Third, chemical control 1. Before bud enlargement, spraying lime sulfur mixture plus 80% sodium pentachlorophenol 200-300 times, eradicate the overwintering germs. 2. Scratch treatment spots. In the dormant period of cherry, first scrape and remove rotten bark, minimize mechanical damage, and then use Baume 3-5 degrees lime sulfur or 40% of arsenic arsenic 50-100 times, three consecutive spots, right Disease control efficiency up to 70% -85%, the effect is more obvious. 3. There is also a certain control effect on the sticky yellow mud on the lesions, but there is no obvious effect of lime sulfur and thiram. The prevention and control of cherry tree dripping gum disease should be based on strengthening the comprehensive management of the orchard, strengthening the resistance of the tree body, and supplemented by the use of adapted chemical control, so as to better prevent the occurrence of leeches and accelerate the development of cherries.
