Second, to exclude the air inside the hood, fill with carbon dioxide gas, the general concentration of about 60%, stable for 24 hours, can kill all insects. Third, through the inspection port at any time to check the storage of mushrooms, the determination of carbon dioxide concentration, concentration control as appropriate. 4.
