Problems solved by technology

In China, the use of microwave technology for sterilization is already in the practical stage, but because the size and structure of pests are different from those of bacteria, the killing mechanism is fundamentally different, so the sterilization technology cannot be used for killing insects, so microwave has not yet bee

Embodiment Construction

[0023] Before using microwaves to kill vegetable insects, the principle of microwave killing vegetable insects and the impact of microwaves on plants and people were studied.

[0024] 1. The principle of microwave killing vegetable insects

[0025] According to the theory of biological effects of high-power microwave (PHM), the thermal effect and field effect of a certain band of narrow-band microwaves have a strong damaging effect on biological cells and nervous systems. It has been proved by microwave theory and experiments that the natural oscillation frequency of water molecules is similar to the microwave frequency of a certain wavelength band of centimeter waves, and can absorb 98% of microwave energy. Tissues with larger dielectric constants absorb more microwaves, and the dielectric constant of water Therefore, the tissue rich in water absorbs the most microwave energy and generates a large amount of heat energy to form a thermal effect, causing the temperature of the ...

Abstract

The invention relates to a method for killing vegetable insects with microwave, belonging to the field of microwave technology and application. For thousands of years, the problem of crop diseases and insect pests has been a trouble for agricultural workers home and abroad. Moreover, as the volumes and structures of the vegetable insects are different from those of bacteria and generated microwave signals cannot be used universally, an oscillation source for generating microwave signals, a modulation signal and the like all need to be improved. According to different shapes of the vegetable insects, by changing the transmission power and the working frequency range of the oscillation source and the repetition frequency and the pulse width of the modulation signal, a high-frequency pulse signal is obtained to replace pesticide to kill the vegetable insects containing more than 60% of water in vivo without causing pollution so that the crop can grow healthily and soil and ground water are prevented from being polluted by pesticide. Therefore, with the wide application, the method certainly has great significance to the production of green food, environmental protection, improvement of the living standard of people and the like.

Description

technical field [0001] The invention relates to a method for killing vegetable insects with microwaves, belonging to the field of microwave technology and applications. Background technique [0002] For thousands of years, the problem of crop diseases and insect pests has been perplexing agricultural personnel in our country and even in the world. In order to kill insects, people have to use a large amount of pesticides, and with the increase of pest resistance, more toxic pesticides must be used. Scientific research has confirmed that a large number of highly toxic pesticides will pollute the environment for a long time and endanger human health. Due to the extensive use of pesticides, their residues will seep into the soil and groundwater, which will be detrimental to the protection of the soil. If things go on like this, the soil and water will also be seriously polluted by pesticides, which will affect the sustainable development of agriculture and increase the impact o...
