1991年～ 1993年作者在内蒙古大兴安岭林区选择有代表性的样地 12块 ,对 6种经口化学毒饵进行了毒饵适口性、毒饵剂型和不同投饵量的野外实验研究。结果表明 ,在林区大面积鼠害控制中 ,应用经口毒饵控制鼠密度 ,首选毒饵为敌鼠钠毒饵 ,投药方法为 2 0 m行距 ,每隔 5 m投放 2 0 g袋装毒饵 ,灭效可达 90 %以上 ,从而为内蒙古大兴安岭林区大面积鼠害防治提供了 1种省时、省料的控制鼠害方法。
From 1991 to 1993, 12 representative plots were selected in the forest area of Daxinganling, Inner Mongolia. Field experiments on six kinds of chemical chewing baits were carried out, including bait palatability, bait dosage forms and different feeding rates. The results showed that in the control of large area of rodent pests, the oral density was used to control the density of rats. The preferred bait was the sodium molybdate which was administered at a distance of 20 m. The bait containing 20 g of bait was dispensed every 5 m. Effective up to 90%, thus providing a kind of time-saving and material-saving method for controlling rodent pests for the prevention and treatment of large-scale rodent pests in the Greater Xing’an Mountains in Inner Mongolia.
