自1980年起采用第一代抗凝血灭鼠剂——敌鼠钠盐毒饵,使90%旅客列车灭鼠达标,社会和经济效益显著。至80年代末期,旅客列车的鼠害又大幅度回升,为害严重,有的专家认为鼠对敌鼠钠盐已产生抗药性。为此,我们于1992年1月,选择283次客车,用敌鼠钠盐毒饵实施灭鼠。结果如下: 一、试验方法:郑州→重庆的283次列车编组 Since 1980, the first-generation anticoagulant rodenticide - the enemy mouse sodium salt bait has been adopted to make 90% of passenger train rodent control standards with remarkable social and economic benefits. By the late 1980s, rodent trains in passenger trains rebounded sharply, causing serious damage. Some experts think that rats have developed resistance to the sodium salt of the enemy mice. To this end, we in January 1992, the choice of 283 passenger cars, with the enemy rat sodium bait implementation deratization. The results are as follows: First, the test method: Zhengzhou → Chongqing train train 283
