一、沼气贮粮作法是:给密封好的粮食贮藏室(库)输入一定比例的沼气,将室内的部分空气排挤出去,使室内的氧气含量下降到3％以下,二氧化碳含量上升到29～38％(正常空气中氧含量为21％,二氧化碳含量为0.03％)。这样,就使贮粮害虫的新陈代谢受到了抑制,继而窒息死亡。据试验,经沼气处理72小时后,各种粮食 First, the biogas stored grain approach is: to seal a good grain storage (library) enter a certain percentage of biogas, the room part of the air out of the room to reduce the oxygen content of less than 3%, the carbon dioxide content rose to 29 ~ 38 % (Normal air oxygen content of 21%, carbon dioxide content of 0.03%). In this way, the metabolism of stored grain pests is suppressed, and then suffocated to death. According to the test, 72 hours after the biogas treatment, a variety of food
