玉树市藏霸喇种畜场应用D 型肉毒灭鼠剂大面积鼠害防治效果调查

Investigation of Control Effect of D-type Botulism Rodenticide on Plateau Pikain in Zangbala Breeding Farm of Yushu

为提高玉树地区寒牧退化草地植被恢复的治理效果,降低高原鼠兔、高原田鼠对试验区草地补播的破坏。本研究以优质燕麦为基饵,拌制添加D型肉毒灭鼠剂浓度为1.5%的毒饵,投放至试验区内0.133万hm^2亩寒牧退化草地,随机划定25×25 m^2样方3个,采用堵洞开洞法计算灭鼠区内鼠害防治效果。样方调查结果显示:平均灭洞率均在90%以上,灭鼠效果良好,为后期草地植被恢复奠定了良好基础。

To improve the effect of vegetation restoration of degraded grassland in Yushu area and reduce the damage of reseeding by Pika and Vole.In this study,high-quality oats were used as the base bait,and the poison bait with type D botulism rodenticide of concentration of 1.5%was mixed and put into the Alpine degraded grassland of 1333.3hm2 of in the test area,and three 25 x25m2 samples plot were randomly selected.The results of the quadrat survey showed that the average rodent control rate of each hole was above 90%,and the rodent control effect was good,which laid a good foundation for the later grassland vegetation recovery.
