磷化铝是国内防治储粮害虫的主要熏蒸剂之一,施药方法普遍采用探管和小布袋多点埋藏投药。小布袋投药,透气性能好,反应完善,防治效果比较显著。但仍有以下几个缺点:1.灌药速度慢。接触药剂时间长,施药人员用汤匙、角匙等工具将药剂灌入每一只小布袋。2.灌药不均匀,药剂灌得有多有少。3.容易污染粮食,因小布袋袋口小,灌药时,药剂难免灌出,粘附在袋口或袋外。所以每到粮食熏蒸季节,特别是早稻入库高温期,仓温、粮温高达38～40度,施药人员已经吃尽了苦头。我们在局党委的领导下,针对了上述问题,组织了有关人员,开展专题攻关,群策群力,通过反复试制革新,终于试制成比较理想的磷
Aluminum phosphide is one of the main fumigants for preventing and controlling stored grain pests in China. Small bag administration, breathable performance is good, the reaction is perfect, the control effect is more obvious. But still has the following several shortcomings: 1. The medicine speed is slow. Contact pharmaceutical for a long time, spraying staff with a spoon, spoon and other tools poured into each small bag. 2. Irrigation is not uniform, how much less irrigation agent. 3 easy to contaminate food, because the small sack pocket mouth, irrigation, inevitably poured irrigation agent, stuck in the bag or bag outside. Therefore, every fumigation of grain to the season, especially the high-temperature storage of early rice, warehouse temperature, grain temperature as high as 38 to 40 degrees, spraying staff have tried their best. Under the leadership of the bureau of party committees, we have targeted the above problems, organized relevant personnel, carried out special projects and made joint efforts to make innovations and finally tried to make the ideal phosphorus
