What are the causes of root disease? How to effectively prevent and control? There are many reasons for the disease in the roots. For example, when the vegetables are single, the vegetables are seriously planted, and the soil environment is poor, the roots of the vegetables will be diseased. Then Xiaobian will simply talk about the difficulty in controlling the root diseases of vegetables. Reasons and countermeasures. First, the root disease is difficult to prevent and cure 1. There are many types of diseases For example, common yellow wilting, withered, wilting, gray mold, stem rot, root rot and other diseases, as well as oomycetes, fungi, bacteria and nematodes, due to different disease prevention methods and pesticides It is different, so some vegetable farmers are difficult to treat differently. 2. Seriously serious Many varieties of greenhouse vegetables are relatively simple, and it is difficult to change them. Therefore, in addition to the reduction in yield and quality caused by heavy mites, the disease will increase year by year, especially in root diseases. Huinong.com suggested that the vegetable farmers should change the different types of crops every 2-3 years. At the same time, they can improve the soil environment and increase the weight by adding organic fertilizer and adding a large amount of biological fertilizer. 3. It is difficult to find diseases in time The pathogenesis of root diseases is invisible in the soil, so it is difficult to find after the onset. One reason is that the main root of the vegetable crop is unique. Once the main root is diseased, the agent used in the necrosis of the meristem can not save the disease. Plant. Second, the response measures 1. First, protect the crop After root disease occurs, water shortage and wilting will occur. At this time, it is necessary to reduce the indoor temperature of the greenhouse, reduce the water required for crop transpiration, increase the humidity in the greenhouse, spray the water on the foliage, or spray aspirin on the foliage to ensure the crop. Will not die due to lack of water. 2. Secondly, the root of the medicine is as follows: a. The medicine is not rooted with water: the amount of medicine required to reach the concentration of the medicine with the water is very large, which will greatly increase the cost. b. When irrigating the roots, the whole shed plants should be irrigated. The single-injection of “dead plants†is difficult to solve. Plants with serious diseases can be irrigated, and plants that are not ill will also be irrigated. c. Note that the concentration of the medicine is slightly higher. d. Avoid “pour a water to dieâ€, pay attention to the filling before the watering or between the two watering, not after the watering.
