Disease control device for agricultural production

Abstract

The invention provides a disease control device for agricultural production. The disease control device comprises a pesticide storage end for being inserted into soil, a fumigation support pipe for being connected with the pesticide storage end and a heat-gathering temperature difference fumigation mechanism for disinfecting the soil, wherein the surface of the pesticide storage end is in threaded connection with the bottom end of the fumigation support pipe, and the surface of the pesticide storage end is conical. The invention relates to the field of agricultural production. According to the disease control device for agricultural production, a special structure for evaporation by means of temperature difference and illumination is designed according to the conditions of long soil disinfection time, serious pesticide waste and non-uniform soil pesticide permeation in the existing ginger planting process and carries out cyclic evaporation and permeation on pesticide liquid, and therefore, the problems that a general soil disinfection device cannot easily control the fumigation trend of a disinfectant, the disinfectant is prone to permeating and sinking, the upper and lower layers of soil are non-uniformly disinfected, the lower-layer soil is high in pesticide content, the pesticide is easily excessive, the upper-layer soil is not fully disinfected, insufficient insect killing is easily caused and the disinfection time is long are effectively solved.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a disease prevention and control device for agricultural production. Background technique [0002] The root-knot nematode pathogen of ginger is widely distributed in the soil, and the disease cycle is long, so it is difficult to control. At present, the soil needs to be disinfected when planting ginger, and a certain amount of chloropicrin needs to be mixed to fumigate the soil. At present, The fumigation method used in ginger planting is to inject chloropicrin into the soil at a certain interval, and then cover it with a film and wait for at least one month. This method mainly uses light to evaporate the pesticides contained in the soil under the film. , disinfect the soil after evaporation, but chloropicrin is oily, and it is easier to flow and penetrate after infiltrating into the soil. It often takes a long time to disinfect the upper layer of soil, and the up...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides a disease prevention and control device for agricultural production, which solves the problem that the general soil disinfection device is difficult to control the fumigation trend of disinfectant, the disinfectant is easy to penetrate and sink, the upper and lower layers of soil are not evenly sterilized, and the lower layer The soil contains a large amount of drugs, which is easy to overdose, and the upper soil is not fully disinfected, which may easily lead to insufficient insecticide and long disinfection time.
