Microwave machine for killing root knot nematodes in vegetables under structure in whole growth period

Abstract

The invention discloses a microwave machine for killing root knot nematodes in vegetables under structure in a whole growth period, which comprises a shell, a microwave transmitter and a soil detector, wherein the microwave transmitter and the soil detector are arranged in the shell and are connected with a controller respectively; the bottom face of the shell has a microwave irradiation through hole; the outer wall of the bottom face of the shell has a microwave irradiation cavity; the bottom face and the surrounding wall of the microwave irradiation cavity are mutually connected to form a closed shape; the top face of the microwave irradiation cavity is open, the opening of the microwave irradiation cavity is connected with the microwave irradiation through hole; one side wall of the microwave irradiation cavity has a plurality of micro through holes; one side wall of the shell is provided with a crop protection plate; crop through holes are formed on the crop protection plate; the outer edge end of the crop protection plate is connected with a microwave reflecting plate at a right angle; and the bottom end of the microwave irradiation cavity and the bottom end of the microwave irradiation plate are on the same plane. The machine can kill root knot nematodes in time when the vegetables grow, and has the characteristics of convenience for use and high killing efficiency.

Description

technical field [0001] The invention relates to a machine for killing agricultural diseases and insect pests, which is a microwave machine for killing root-knot nematodes in the whole growth period of protected vegetables. Background technique [0002] Because root-knot nematodes are especially suitable for breeding and growing in an environment with a soil temperature of 25°C-30°C, root-knot nematodes in temperate tropics and northern protected areas are the main diseases that cannot be killed by physical methods in this field. Therefore, the use of It is a common and usual method to kill root-knot nematodes with highly toxic pesticides, and "poisonous vegetables" are born from this, which cannot be eliminated. Using microwaves to kill root-knot nematodes is a purely physical method without soil pollution, environmental pollution and water pollution. Currently disclosed microwave insecticides, due to the deficiencies in their structure and other aspects, cause no products ...

AI Technical Summary

Problems solved by technology

However, the damage period of root-knot nematode to crops occurs during the whole growth period of crops, causing crops to wilt, turn yellow and die

Since there is no simple, easy-to-implement, and effective physical method to kill vegetable root-knot nematodes, current vegetables can only use a large amount of pesticides during the growth period, and even highly toxic pesticides can be used to kill root-knot nematodes. It is one of the main causes of the existence of "poisonous vegetables"
