A detailed explanation of new grain insect-killing technology, scientific prevention and control of grain pests
In rural areas, this phenomenon is often encountered: when farmers spray pesticides, they do not know what pesticide they are using, nor how many times it should be diluted, and only know how many caps (pesticide bottle caps) to mix into a bucket of water. This is the true portrayal of how most Chinese farmers use pesticides today. Of course, this current situation has to do with rural...
Japan's Mitsubishi Heavy Industries has developed a technology that kills pests in rice and other grains by increasing and decreasing carbon dioxide pressure. Compared with traditional methods, the new technology causes less environmental damage and less harm to the human body.This technology uses the principle that suddenly reducing pressure under a high-pressure state causes an object to expand. Specifically, the rice is placed in a treatment tank and carbon dioxide is introduced. The carbon dioxide penetrates into the bodies of adult pests, larvae, and the interior of eggs, while hardly penetrating into the grain kernels. The pressure in the tank is then raised to 30 atmospheres, maintained for several minutes, and then suddenly reduced. At this point, almost all pests die from their bodies expanding and bursting, the eggs are also destroyed, and the grain kernels are basically unaffected.
