Now more and more fruit farmers choose orchard sprayers, but there are many specifications, models and manufacturers of orchard sprayers on the market. So, how to choose an orchard sprayer? First, we must understand the types of orchard sprayers Including self-propelled, suspended, and towed. Among them, both the suspension type and the traction type require tractors as supporting power. The former is economical and practical, with strong mobility, while the latter has strong climbing ability and is suitable for dense planting or sloping orchards. Secondly, we must understand the structure of the orchard sprayer. Orchard sprayer is mainly divided into two parts: power and spray. The spraying part is composed of liquid tank, fan, plunger pump or diaphragm pump, pressure regulating distribution valve, filter, suction valve, transmission shaft and spraying device, etc. There are several nozzles on each side of the nozzle, arranged in a fan shape, adjustable Spray range. Finally, it is necessary to be clear about the working principle of the orchard sprayer. When the tractor's rear output drives the liquid pump, the water in the medicine tank enters the liquid pump through the head, switch, and filter, and then passes through the return pipe and the mixing pipe of the pressure regulating distribution switch. Enter the medicine tank. While adding water to the medicine box, add pesticides and mix them in the required proportions. When spraying, the liquid medicine in the medicine tank enters the liquid pump through the outlet pipe, filter and the inlet pipe of the liquid pump. Under the action of the pump, the liquid medicine enters the main switch of the pressure regulating distribution valve from the outlet pipe of the pump, and passes The medicine tube enters the nozzle of the spray device. At this time, the pressurized liquid medicine is sprayed out in a mist under the action of the nozzle, and the strong air flow generated by the fan will atomize the mist again, and at the same time blow the atomized fine mist to the canopy of the fruit tree.

Mycoplasma pneumoniae is one of the smallest free-living microorganisms, intermediate in size between bacteria and viruses (6). Its small genome and size make diagnosis difficult. Bacteria are not visible on Gram staining and cannot be grown on standard bacterial media.

Chlamydia pneumoniae is an important cause of acute respiratory infections, but may also be associated with chronic diseases (24). Because chlamydia pneumoniae was different from other types of chlamydia, a new name was proposed for the bacterium, chlamydia pneumoniae. Although the overall incidence is unknown, there are an estimated 2 to 5 million cases of pneumonia and 500,000 pneumonia-related hospitalizations in the United States each year, according to CDC estimates. While all age groups are at risk, it is most common in school-age children. In addition, according to some researchers, mycoplasma pneumoniae infection may be associated with atherosclerotic vascular disease, as well as Alzheimer's disease, asthma, and reactive arthritis.
