Air-conditioning control system of killing crop pests by biological floating bed

Abstract

The invention discloses an air-conditioning control system of killing crop pests by a biological floating bed, which belongs to the air-conditioning device for preventing plant diseases and insect pests and aims at providing an air-conditioning device for killing plant diseases and insect pests of water crops. The air-conditioning device comprises a biological floating bed, an air supply device and a tail gas recovering device, wherein a transparent plastic tent (1) is closely covered on the biological floating bed (2), the air supply device comprises a gas mixing box (5), an oxygen supply device (7) and a carbon dioxide supply device (8) and a nitrogen supply device (9) which are respectively and sequentially communicated with the gas mixing box through a reducing valve (14) and a flow meter (13), an air inlet pipe (3) communicated with the gas mixing box (5), and an air outlet pipe (12) communicated with the tail gas recovering device (10), and the air inlet pipe and the air outlet pipe are respectively led into the plastic tents (1). The invention has the advantages of no pollution and residue, safety, environment protection, good pest killing effect and the like, and is an ideal device for killing the plant diseases and insect pests of the water crops.

Description

Technical field: [0001] The invention relates to a device for preventing and controlling crop diseases and insect pests, in particular to a device for killing water surface crop diseases and insect pests by utilizing non-residue controlled atmosphere technology. Background technique: [0002] Chemicals are a common way to kill crop diseases and insect pests. This method is highly toxic, has a low safety factor, and is not friendly to the environment. With the increasing awareness of environmental protection, many chemical agents have been listed as banned products. Due to its advantages of environmental protection and low residue, the modified atmosphere insecticidal technology has once again attracted the attention of the world, and has gradually become the mainstream technology for preventing and controlling pests and diseases in stored materials. However, the existing modified atmosphere insecticidal devices have defects such as relatively single gas types, or the combin...

AI Technical Summary

Problems solved by technology

However, the existing modified atmosphere insecticidal devices have defects such as relatively single gas types, or the combination concentration of various gases cannot be precisely controlled, so the effect of pest control is not ideal; and the tail gas has not been recovered. Conducive to environmental protection

In addition, most of the current controlled atmosphere insecticide technologies are only used to prevent and control pests and diseases of stored products, but not for the control of pests and diseases of growing crops.
