在敌敌畏中掺入酒精与磷化氢混合环流熏蒸 ,使混合气体在粮堆内均匀分布 ,解决了敌敌畏在粮堆内的施药难题 ,达到彻底防治书虱的目的。
The results showed that the concentration of PH 3 can maintain 100 mL/m 3 for 47 days,and the distribution of PH 3 was uniform after 72 hours.
5 g/m3磷化铝 ,在高大平房仓进行粮面施药自然潮解磷化氢环流熏蒸 ,保持仓内磷化氢气体浓度在 1 0 0mL/m3以上 4 7天 ,投药 72小时 ,气体分布均匀。
The optimum application dosage of PH 3 fumigation were discussed,and the two methods,application only once and application two times for recirculation were compared.
