我县由于仓容不足,其中有40%粮食常年露天储存.露天储粮害虫的防治药剂主要是磷化铝,每年至少熏杀一次,一部分要进行两次.“磷化铝小包分散埋藏法”是我县熏蒸露天储粮害虫的常规方法.这种方法很容易造成局部的高浓度,而产生自燃自爆现象,所以不得不拆除苫盖堆囤的草席及防鼠裙等. 在我县磷化铝是露天储粮害虫防治的唯一杀虫剂.由于设备条件差,尽管采取了很多方法,但熏蒸效果仍不理想,达不到彻底杀灭害虫的目的.这次试验正以解决上述问题为目的进行的.
In our county, 40% of the grain is perennially stored in the open because of insufficient storage capacity. The chemical for pest control of open storage is mainly aluminum phosphide, which is smoked and killed at least once a year and twice in part. My county fumigation of open storage pests in the conventional method .This method is easy to cause local high concentrations, and the phenomenon of spontaneous combustion self-explosion, it had to dismantle the cover mast hoarding and rodent skirts, etc. In our county of phosphate Aluminum is the only pest control agent for pests stored in the open air.Due to poor equipment conditions, the fumigation effect is still unsatisfactory and can not reach the goal of completely killing pests though many methods are taken.This test is trying to solve the above problems The purpose of the.
