塑料薄膜密闭条件下的低剂量磷化铝熏蒸是低水份储粮害虫防治的主要方法。为探讨磷化氢毒气在此条件下的存在状态。毒效及施药技术,我们结合生产实践在81年至83年的熏蒸防治工作中,使用剂量为0.63—2.37克/米
Low-dose aluminum phosphide fumigation under plastic film confinement is the main method for pest control of low-moisture stored grain. To explore the presence of phosphine gas in this condition. Toxicity and application of technology, we combine production practices in the 81 to 83 years of fumigation prevention and control work, the use of doses of 0.63-2.37 g / m
