我们经过数年观察发现:仓房做熏蒸处理后,当时效果很好,但时过不久,多则三个月,少则15天,在粮堆的压盖物上或粮堆表层又出现了虫种不一,数量不少的活虫.这些活虫是从何而来呢?通过观察发现:它们是通过仓门空隙这个易被人们忽略的缺口潜入的.这个新的发现,应当引起我们仓储工作者高度警惕!既然那些活虫能从门缝里进入粮仓,那么,我们就应该研究对策,铲除它们.为此,我们在仓门口设置了粮食仓储的重要防线,即防虫线.
After several years of observation, we found that after the warehouse was fumigated, the effect was very good at that time. However, shortly afterwards, as many as three months and as little as 15 days, insects appeared on the gland of the grain piles or on the surface of the grain piles Species, lots of live worms come from these living things come from? Observations found that: they are through the door gap that is easy to overlook the gap sneaked into this new discovery should cause us to warehousing The workers are very vigilant! Now that live insects can enter the silo through the door, we should study countermeasures and eradicate them. For this reason, we set up an important line of defense for food storage at the gate, that is, pest control lines.
