There are many reasons for cherry root rot, and it may also be poor air permeability. Air permeability is an important index to evaluate soil, and it is also an important reason to affect root development. It often happens that the soil is hardened, the air permeability is poor, and the root system is poorly developed, which leads to the premature aging and yield reduction of vegetables. Under normal circumstances, the roots of saplings are generally not disinfected when they are planted, so the roots generally do not carry too many harmful bacteria and do not have much impact on the roots.

Most root rot diseases start from fibrous roots. At first, reddish-brown spots appeared around the fibrous roots, then slowly spread, and finally spread to the growing fibrous roots, and the disease slowly spread to the whole root until the whole root was necrotic. The causes of cherry root rot are: too much water leads to long-term soaking of roots, which leads to airtight soil and air, and makes cherry roots rot. Maintaining the permeability of cherry root soil can improve root rot. The storage nutrition of trees is seriously inadequate. Poor orchard management, no topdressing in summer, no base fertilizer in autumn, and serious lack of nutrients in trees, leading to rampant rot. A large number of human and animal feces that have not been fermented and decomposed are directly applied to the orchard soil, and a large number of germs, pests, salt, etc. What it carries will cause serious damage to the root system, and more seriously, it will cause rotten roots and dead trees.

In spring, after removing the soil from the root neck, check the root neck cortex tree by tree, scrape it off in time after finding the diseased spots, smear the wound with 30 times of 4% nongkang 120 aqueous solution, and burn the scraped diseased belt out of the garden. There is a serious shortage of organic matter in the soil, beneficial bacteria lose their living environment, and harmful bacteria multiply in large numbers, leading to rotten roots and dead trees, serious depletion of trace elements in the soil, serious physiological diseases and declining fruit quality. At the beginning of the disease, the leaves will turn yellow and wither, and slowly the leaves will fall off until the whole plant dies. In summer, if it suddenly clears up after continuous rain, it will lead to the sudden death of the diseased plant.
