谷类贮藏时一般采用熏蒸法防治害虫,但此法仅能杀死幼虫和成虫,而对附着于谷类上的虫卵无破坏作用,因此不能彻底防治谷类害虫。现有一种新方法,可以解决这一问题。将脱氧混合物密封在透气度为200～100000秒/100ml的通气性包装材料中,再与谷类一起密封于氧浓度0.5％以下的非通气性包装材料或气密容器中,在5～ Fumigation method is generally used to control pests during grain storage, but this method can only kill larvae and adults, but has no damaging effect on the eggs attached to cereals. Therefore, cereal pests can not be thoroughly controlled. There is a new way to solve this problem. The deoxygenated mixture is sealed in an air-permeable packaging material having an air permeability of 200 to 100,000 sec / 100 ml, and then sealed together with cereal in a non-air-permeable packaging material or airtight container having an oxygen concentration of 0.5% or less,
