| 摘 要： | 对高大平房仓磷化铝粮面投药后磷化氢自然扩散渗透情况进行检测,并对熏蒸杀虫效果进行了试验,检测分析了不同仓房不同温度和同一仓房不同温度下磷化氢的扩散速度和分布规律.试验结果表明:高大平房仓由于粮堆内外温差的存在,粮面施药后磷化氢气体在相对比较短的时间内借助粮堆内的微气流扩散到粮堆的各层,并能分布均匀,而且粮堆内温差越大,磷化氢气体扩散速度越快,气体分布达到均匀的时间越短.

| Abstract: | The permeability of PH3 and the fumigation effect against insects were tested after applicated AlP on the surface of grain bulk in large warehouse.The permeability speed and distribution law of different warehouse at the different temperature and in the same warehouse at the different temperature were analyzed respectively.The results showed that because the temperature is different between inside and outside of grain bulk,PH3 can well-distributed in a short time by tiny air flow after application.The greater the temperature difference,the quicker the distribution speed is,and the time of well-distribution is shorter. |
