摘要
选择新建高大平房仓进行了不同磷化氢浓度、不同间歇方式、不同密闭时间进行环流熏蒸杀虫试验 ,从中探索了高大平房仓仓内磷化氢浓度衰减规律、粮堆内磷化氢气体分布的均匀性、最佳熏蒸剂量、最佳间歇方式、密闭时间及最佳熏蒸效果和环流熏蒸对粮温的影响等 .
Different phosphine concentrations,intermittent methods and airtight times were tested to kill insects by circulating fumigation in new built one story tall silo.It investigated the reguarities of phosphine concentrations decline,phosphine even distribution,the best dosage of fumigant and intermittent method,the airtight time and the best fumigation effect,and effectiveness of circulating fumigation to the grain temperature.
