最近,联邦德国 Stabl,E.和 Rau,G.报道一种叫做压力膨胀(Pressure expansion)简称 PEX 的灭虫新技术。即利用熏蒸剂 CO_2,通过一定设施加压施入气体达到农产品熏蒸除虫的目的。CO_2和其它常规熏蒸剂相比,具有成本低、安全适用的特点。将气体在10—20分钟内以10—50巴的压力施入,使其迅速膨胀而杀死害虫。在试验中对赤拟谷盗的卵和成 Recently, Federal Republic of Germany Stabl, E. and Rau, G. reported on a new technology called pest control called Pressure Expansion (PEX). That the use of fumigant CO_2, through certain facilities pressurized gas into the flue gas to achieve the purpose of fumigation. Compared with other conventional fumigants, CO_2 has the characteristics of low cost and safe application. The gas is applied within 10-20 minutes at a pressure of 10-50 bar, causing it to rapidly expand to kill pests. In the trial on the red eggs and into a net tilting
