露天储粮易受害虫危害,而且是虫害感染快,发展快,严重虫粮多,目前,主要依靠化学药剂熏蒸进行防治。研究探索安全、经济、有效的施药方法,是摆在我们面前的一个迫切需要解决的问题。我们根据本地露天储粮大部分能进行机械通风及粮面不便施药的特点。选择了利用现有露天储粮的通风系统,在基本上不增加其它设备的条件下,将磷化铝药剂投入风道让其挥发,然后通过风机压入式作业,将已挥发的磷
Open storage of grain susceptible to pests, insect pests and infection is fast, rapid development, severe pest and more food, at present, mainly rely on chemical fumigation for prevention and treatment. Studying the safe, economical and effective drug application methods is an urgent problem that needs to be resolved before us. According to the local open-air storage grain most of the mechanical ventilation and food noodles easy to apply characteristics. Choose to use the existing open air grain storage ventilation system, basically do not add other equipment conditions, the aluminum phosphide pharmaceutical into the airway to volatilize, and then through the fan press-in operation, the volatile phosphorus
