In spring, budding and flowering of fruit trees require large amounts of nutrients, so fertilization in spring is critical. The process of fertilization needs to grasp the points to prevent the occurrence of fertilizer. Some farmers found that 1-2 weeks after fertilization, the young leaves or buds of the big branches or entire trees of the tree were found to have shrunk and dried, and the flowers and young fruits were atrophied and fell off. The bar-like bark on the back showed watery ulceration. In severe cases, all the large branches died or even the entire tree body. Death, causing serious damage. The main reason for this phenomenon is the burning of fertilizer. Northern fruit trees are the most vulnerable to fertilizer damage. How to avoid To avoid the occurrence of fertilizer damage, the following methods can be used: first, the correct method of fertilization should be selected. At present, fruit growers mostly use hole method (four holes are digged in four directions around the tree body), fertilization groove, and ring groove fertilization method. Or the whole garden spreads fertilization. However, it is generally not recommended to use acupuncture, especially peach, apple, citrus, apricot and plum. Fertilization of fruit trees is best combined with the use of composted soil and fertilizer. The use of ring groove, radiation groove fertilization pay attention to not apply too deep or too close to the root; fertilization site can not be too close to the trunk. The second is to choose the right fertilizer. If there is fertilizer damage after fertilization, timely remedy is the key to avoiding greater losses, and you cannot hold on for a chance to delay treatment. The fertilizer damage should be discovered in time, and the corresponding large roots should be looked for in the extension direction of the branches showing the symptoms of fertilizer damage. If the root part is found to be black and rotten, it can be scraped off with a cutter; if the roots are rotted badly, the affected part can be cut off, and the rotting can be taken from the main part. The cadres cut off the roots and dried them for 1 to 2 days to avoid flooding. Disclaimer: Some articles in this website have been transferred from the Internet.
