十年来,我库采用缺氧方法,防治储粮害虫的实践,使我们掌握了防治储粮害虫的主动权,使每吨粮食的害虫防治费用下降到0.15—0.20元,深受粮库工人的欢迎。 粮油种子自身的呼吸、后熟等生理作用,以及储粮害虫的呼吸、繁殖等生命活动,都要吸收氧气,放出CO_2。如果使粮堆外用塑料薄膜密封,就会造成粮堆内空气组成的改变。据试验,氧浓度在2％以下,玉米象、脊胸露尾
Over the past ten years, our library has adopted the method of hypoxia to prevent and control the pests of stored grain. This has enabled us to seize the initiative in preventing and controlling stored grain pests, reducing the cost of pest control per tonne of grain to 0.15-0.20 yuan, welcome. Oil and seeds of their own breathing, ripening and other physiological effects, as well as stored grain pests respiratory, reproductive and other life activities, must absorb oxygen, emit CO_2. If the outer plastic foodstuffs are sealed, the composition of the air inside the grain piles will change. According to the test, the oxygen concentration below 2%, corn, chiropractic tail
