for greenhouses gas pest control system

Abstract

The invention discloses a greenhouse gas disease and insect pest control system, comprising a greenhouse, an ozone generator is arranged outside the greenhouse, the support column is fixedly connected to the middle wind guide plate, and the rotating rod is fixed Rotating blades are provided, a sphere is fixedly arranged on the pressure rod, an air vent is provided at a position corresponding to the sphere on the lower baffle, a screen plate is movably arranged on the guide rail; A return pipe, the return pipe extends to the interior of the greenhouse and communicates with the ozone pipe, and the exhaust pipe communicates with the irrigation water tank. The invention provides a greenhouse gas disease and insect pest control system, the ozone distribution is more uniform, the concentration difference between the near end and the far end is small, and the ozone gas can be recycled to improve the insecticidal effect on tall seedling crops, and the excess ozone is also It can be dissolved in irrigation water for recycling, easy to operate, and effective in controlling diseases and insect pests, and is very worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of pest control, in particular to a gas pest control system for greenhouses. Background technique [0002] In the prior art, a greenhouse fruit and vegetable disease ozone control system with the application number "201510544764.1" includes an ozone generator, an ozone concentration sensor, an intelligent controller, an ozone leak pipe and a fan; the ozone generator and the fan are placed in the greenhouse Outside, and the air inlet of the fan is connected with the ozone outlet of the ozone generator through the gas delivery pipe; the ozone leakage pipe is horizontally erected in the greenhouse, and the end close to the fan extends out of the greenhouse and communicates with the outlet of the fan ;Ozone concentration sensors are evenly distributed on the upper and lower sides of the ozone leak pipe; the intelligent controller has a built-in signal converter, microprocessor, relay and controller, wherein the ...

Problems solved by technology

[0003] But in its use, there are still relatively obvious defects: 1. The above-mentioned device discharges ozone by offering air leak holes on the ozone leak pipe, but the ozone diffusion after this discharge is very uneven, and the distance More ozone will be discharged from the leak hole at the closer end of the ozone generator, causing the problem that the ozone concentration is too high to damage the crops, and there is even no ozone at a little distance, which cannot guarantee the effect of ozone gas on pest control; 2. Ozone The specific gravity of the ozone is greater than that of the air, so the ozone will soon fall to the ground after being discharged. Although it can control the diseases and insect pests of the low crops, the ozone and the high seedling crops do not have sufficient contact time, so the overall control effect is relatively low. Poor; 3. When the ozone is added too much, or the remaining ozone needs to be discharged after use, the above device can only discharge the ozone gas directly into the external environment. If it is too much, it will not only cause pollution, but also have potential safety hazards. big waste of resources
