混凝土立筒库是近年在我市投产使用的新仓型.在原建筑设计方面没有考虑熏蒸杀虫的设施.小麦在储存期间害虫生长繁殖迅速,特别是在高温季节为害严重,据记录每年由六月下旬至十月上旬小麦经一百余天储存虫口密度一般可发展到300～400头/公斤.许多粮粒被蛀蚀成空壳或带有粉状,加工时的出粉率和产品质量下降,造成经济损失.为了探索适合我市立筒库防治害虫的方法,根据立筒库害虫集结在上、下两粮层活动的规律来探求防治办法.据观察:立筒库筒区中层粮食含氧量较低,处于缺氧状态,
Concrete vertical tube library is put into use in our city in recent years, the new warehouse type in the original architectural design did not consider fumigation insecticidal facilities.Peters during storage rapid growth and reproduction of pests, especially in the hot season, serious damage, it is recorded by the annual six In late October to early October, the density of stored insects in wheat over a hundred days can generally be increased to 300 to 400 heads / kg. Many grain grains are eroded into an empty shell or with a powdery form, and the output of flour and the quality of products during processing decrease , Resulting in economic losses.In order to explore suitable for our municipal tubular pest prevention and control methods, based on the vertical cylinder pests assembled in the upper and lower layers of the law of activity to explore ways to prevent and cure.It is observed: Low volume, in hypoxia,
