摘要
在固原林区,应用克鼠星 1号 (Krs1#)灭鼠剂进行鼢鼠防治, 2个防治区内,林木死亡率分别比对照下降了 9. 2%和 5. 7%,鼢鼠的有效洞率分别下降 18. 0%和 28. 9%。在地面害鼠的防治中,防治区林木死亡率分别为 6. 0%和 5. 8%,而对照区为 41. 2%和 35. 4%,防治后的地面害鼠洞口密度分别为 12. 1个 /m2 和 10. 6个 /m2,对照区为 14. 3个 /m2 和 12. 4个 /m2。应用克鼠星 1号防治后,由害鼠引起的林木死亡率显著降低,经方差分析,防治区和对照区差异显著。同时,探讨了不同害鼠的投饵方法和投饵量。
The results show that the tree's death rates in treatment are reduced by 9.2% and 5.7% than control, and the rate of effective zokor cave are reduced 18.0% and 28.9%, by making use of Krs1~# to control zokor. In controlling other mouse, the tree's death rates in treatment are 6.0% and 5.8%, the cave density are 12.1/m^2 and 10.6/m^2; but in control, the tree's death rate are 41.2% and 35.4%, the cave density are 14.3/m^2 and 12.4/m^2. There is a remarkable difference between treatment and control by analysis.
