Plant diseases can generally be classified into non-infectious diseases and infectious diseases. Non-communicable diseases are diseases caused by plants on unsuitable soils, or encounter unfavorable weather, moisture, and fertilizers; Infectious diseases are caused by bacteria and can be transmitted. No matter what kind of plant diseases, the impact on plants is very large. At the same time, because the plant diseases are invisible, the characteristics of the early stage diseases are not obvious, so plant disease detectors are used to quickly identify the types of plant diseases. It is of great significance for the scientific prevention and control of pests and diseases.
After a plant becomes ill, some common symptoms, such as discoloration, spotting, dwarfing, tufting, yellowing, necrosis, rot, wilting, shrinking leaves, shrinking fruit, distortion, tumor, malformation, etc., generally appear. However, the prevention and control of these plant diseases can often lead to the best opportunity to prevent and control plant diseases. The control effect will be greatly discounted, and the application target of plant disease detectors will be at the early stage of plant diseases. These plant diseases are diagnosed, and it is determined what kind of diseases are caused, so that scientific and reasonable targeted prevention and control measures can be formulated according to the test results, and the harm of plant diseases can be killed in the cradle.
The plant disease detector is a scientific detection instrument that converts analog signals into digital signals, enabling rapid diagnosis of plant diseases, rapid analysis and determination of various types of crop diseases, diagnosis of the cause, remedy of the disease, how to prevent pests and diseases, and science The medication provides a scientific and rational theoretical basis. At present, the application of scientific instruments in agriculture is a development trend. Therefore, the application of plant disease detectors is becoming more and more widespread at the grassroots level. The plant protection departments throughout the country are actively deploying plant disease detectors to carry out the prevention and control of plant diseases. The instrument also played an important role in the actual work. The application of plant disease detectors has greatly improved the level of prevention and control of modern agricultural plant diseases and provided guarantees for agricultural production.
