Study on wood fumigation technology in tent

为严防俄罗斯林木检疫性有害生物随原木传入境内 ,本文以火车装载的俄罗斯进境木材为对象 ,用溴甲烷对原木进行了熏蒸处理试验。在环境温度 1 5℃以上 ,采用了不同的投药剂量和熏蒸时间进行试验。通过熏蒸效果系列检测 ,投药剂量 1 0 0 g/m3、80 g/m3、60 g/m3、50 g/m3、经 1 2h熏蒸 ,对天牛、小蠹、吉丁虫的幼、成虫、叶甲成虫等害虫死亡率为 1 0 0 % ,投药剂量 50g/m3、熏蒸 1 2h为最佳剂量和熏蒸时间。

The log imported from Russia by train was fumigated with bromo Gas in order to prohibit the forest pest from spreading into our country from Russia.When enviromental tempreature was above 15℃,diferent dosage and fumigation time was selectedd.The test results showed that when the dosage is in the scope of 100g/m 3,80g/m 3,60g/m 3 and 50g/m 3,with fumigation time of 12h,the death rate of long horned beetle,the Scolytidae,the larva and adult of Buprestidae,the adult of leaf beetle were 100%.The 50g/m 3was the best dosage,and 12h was the best time of fumigation.
