Over the years, there have been many crops that have been harmed by powdery mildew, such as wheat powdery mildew, melon powdery mildew, strawberry powdery mildew, grape powdery mildew, apple powdery mildew, powdery mildew, and powdery mildew, although it is said that the white powder on different plants The pathogenic genus is different, but it is certain that the occurrence of plant powdery mildew is related to mycelia or conidia. Therefore, powdery mildew cannot be prevented because we have not yet used the remote camera spore capture instrument. The spore monitoring of the disease in the field has been strengthened and the best time for treatment has been missed. Therefore, the best way to control powdery mildew in modern agriculture is to use remote photo spore traps to enhance remote real-time monitoring of spores and to guide the timely and effective monitoring of spores. Scientific prevention. In general, conidial formation and germination have different requirements on the environment. Powdery mildew requires higher temperatures and relative humidity when forming conidia. At the time of germination, lower relative humidity is needed. Therefore, it is favorable for the occurrence and prevalence of powdery mildew to be clear after the rain, or in the hot weather with large temperature difference between day and night. In fact, many experienced agricultural workers are fully aware of this fact. However, it is necessary to timely detect the occurrence of conidia and monitor its quantitative status, and to carry out disease prevention and control in a timely manner. Scientific professional instrument - remote photo spore capture instrument for monitoring and analysis. In many cases, powdery mildew is uncontrollable. The main reason is that the treatment time is too late. Under suitable conditions, the powdery mildew has a large amount of reproduction and is widely distributed, making it difficult to stop it. Once the lesions expand, on the one hand, a large number of white spores have matured, which will cause rapid proliferation. Second, the nutrition of the cells in the leaves has been dried by the white spores, and the resistance to disease has been greatly reduced. When the lesion expands or a large-scale outbreak occurs, it is difficult to spray evenly with a large number of leaves and it is difficult to control it. Therefore, the prevention and treatment of plant powdery mildew should be done as early as possible and early prevention and control. In addition to the prevention and control process, long-range photo spore capture devices are used to strengthen spore monitoring, and cultivation management should be strengthened to create a disadvantage. Powdery mildew occurs in the development of the environment to ease the spread of the disease.
This SCR system adopts mutilayer Nylon Tube made of ETFE/PA12. These tubes hace excellent performance of corrosion resistance and low Urea solution permeation. They meet the requirements of SAE J844. SCR system is made up of supplying tubes, returning tubes and injection tubes.
Because of the flexibility of the pipeline, the pipeline is often used in hydraulic systems and other mechanical devices driven by liquid. Because of the various parts of the car generally dispersed installed in various parts of the car, the car line like blood vessels in the body, responsible for linking these dispersed components, so that the complete system of automobile work orderly.
