粮食在储藏期间,如何做到少用药以至不用药来保管好,这是一个关系到人民健康的大问题。目前在粮食仓库较为广泛采用的“化学保藏”和“熏蒸杀虫”等方法,虽然对抑制虫霉起了一定作用,但是,这些方法使用化学药剂的剂量都较大,污染粮食,成本高,有效防治期也较短,一般药效仅能维持几个月,长期保管的粮食,一年至少要熏蒸处理2～3次,每万斤需处理费用3～5元,特别是对人的身体健康有一定的影响。“自然缺氧”储藏方法试验成功后,为保管好粮食开创了新途径,这种方法主要是利用粮食本身以及粮堆内害虫、微生物的呼吸作用来消耗粮堆中氧气,改变粮堆内气体成份,造成缺氧环境,以抑制虫霉的繁殖危害。由于方法简便易行,深受广大保粮人员欢迎。但“自然缺氧”的降氧速度与粮食 During the storage of food, it is a big issue that concerns the health of the people how to use less medicine and not to take medicine. Although the methods of “chemical preservation” and “fumigation and insecticide”, which are widely used in grain storage, play a certain role in the inhibition of Mycoplasmaphrax, these methods use large doses of chemical agents to pollute foodstuffs and have high cost, Effective control period is also shorter, the general efficacy can only be maintained for a few months, long-term storage of food, fumigation at least a year to handle 2 to 3 times per kilogram to be processed costs 3 to 5 yuan, especially for the human body Health has a certain impact. After the test of “natural hypoxia” storage method, it succeeded in opening a new way for keeping good food. This method uses the respiration of food itself and the pests and microorganisms in the grain pens to consume the oxygen in the grain piles and change the gas in the grain piles Ingredients, resulting in hypoxia environment, in order to inhibit the propagation of insect mold hazards. As the method is simple and convenient, welcomed by the majority of food security staff. But the “natural hypoxia” rate of oxygen reduction and food
