二氧化碳充气法是使仓库空气中含有60％的二氧化碳(保持四天),这样就促使害虫的呼吸频率加快,导致虫体迅速失水,最后枯竭致死。这种方法具有与二溴乙烷相同的效果,且无毒性。其设备制作也较简
Carbon dioxide aeration method is to make the warehouse air contains 60% of carbon dioxide (for four days), so that to promote the respiratory rate of pests to speed up, resulting in rapid loss of parasites and eventually dried up to death. This method has the same effect as dibromoethane and is non-toxic. Its equipment production is also relatively simple
