Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plant protection, especially to a kind of back-carrying lossless ozone plant protection device. BACKGROUND

[0002] In modern agricultural production, vegetable planting faces many challenges, especially the prevention and control of diseases and pests. Traditional disease and pest control methods rely heavily on the use of chemical agents, which are widely used in fields by portable pesticide application devices. However, the overuse of chemical agents not only causes serious environmental pollution, such as soil and water pollution, but also may lead to drug residues on the surface and inside of vegetables, thereby endangering human health. In addition, long-term use of chemical agents can also lead to drug resistance of diseases and pests, increasing the difficulty of prevention and control.

[0003] To find more environmentally friendly and efficient disease and pest control methods, researchers have begun to explore the application of green disinfectants. Ozone, as a strong oxidizing agent, is considered an ideal green disinfectant due to its rapid bactericidal effect, broad spectrum and no residual characteristics after treatment. Ozone water, which is made by passing high-concentration ozone gas into water, further enhances the bactericidal and disinfecting ability of ozone and its decomposition catalytic effect. Currently, ozone water has been widely used in water treatment, aquaculture, food disinfection and other fields, and has achieved remarkable results.

[0004] However, when ozone water is applied to disease control in agricultural production, there are still some technical difficulties. In particular, during the spraying of ozone water, the volume of the sprayed droplets is small, which increases their specific surface area, causing the dissolved ozone in water to easily escape, resulting in a decrease in effective concentration. This not only affects the bactericidal effect of ozone water, but also reduces its utilization efficiency.
