在气密性良好的粮仓内通入CO2 气体来改变粮仓内气体的组成 ,使粮仓中的昆虫因缺氧窒息而死亡。试验表明 :CO2 气调技术能完全杀死粮仓内昆虫成虫、卵、蛹和幼虫 ,有效保持粮食较高品质和延长储藏期 ,不会产生任何残留污染 ,是一项能完全替代磷化铝的储粮新技术。
CO2 gas is introduced into the gas tight granary to change the composition of the gas in the granary so as to cause the insects in the granary to die of suffocation due to lack of oxygen. The experiment shows that the CO2 gas-phase technology can completely kill adult insects, eggs, pupae and larvae in the grain silo, effectively preserves the high quality of the grain and prolongs the storage period without any residual pollution, and is a completely replaceable aluminum phosphide New grain storage technology.
