摘要
本文对平房仓低温粮堆表面生虫,采用粮堆表面投药、依靠微气流扩散的熏蒸方式和环流熏蒸的杀虫对比试验,两者都取得较好的杀虫效果。虽说环流熏蒸对粮堆整体的“冷芯”影响不大,但对底层粮堆的温升有一定的作用,建议在北方地区高大平房仓低温粮堆表面生虫时采用粮面投药的杀虫方法。
Two methods of fumigationputting ALP into the surface of the grain bulk diffusing PH3 by microairflow and reeireulation fumigation were compared. The results showed that the two methods had good effect. Reeireulation fumigation have a tiny influence upon the temperature of the cold core but a distinct influence upon the bottom of the grain bulk. The methods putting ALP into surface of the grain bulk and diffusing PH3 by mieroairflow is well commended to kill the insect in the surface of the grain bulk in the large warehouse in the north.
