Abstract
应用20.02% 地芬·硫酸钡饵剂对森林害鼠进行药效防治和适口性试验.结果表明:在黑龙江省试验地20.02% 地芬·硫酸钡饵剂低,中,高投药量为2,3,4 kg/hm2的灭鼠效果分别为50.00%,75.00%,92.93%;在青海省同样低,中,高剂量的灭鼠效果分别为53.77%,77.60%,82.12%.随着投药剂量的增加,灭鼠效果也相应的提高.害鼠对20.02% 地芬·硫酸钡饵剂的摄食量较高,适口性能够满足对害鼠防治的要求.饵剂投药剂量为4 kg/hm2时,对棕背鼠平Clethrion-omys rufocanus和达乌尔鼠兔Ochotona dauurica等多种害鼠的防治效果高于对照药剂溴敌隆.
