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。
In the Guyuan forest area, the rats were treated with Krs1 # rodenticides for control. In the two control areas, the tree mortality rates decreased by 9.2% and 5.7% The effective hole rate decreased by 18.0% and 28. 9% respectively. In the prevention and control of ground pest rats, the forest mortality rate in the control area was 6.0% and 5.8% respectively, while that in the control area was 41.2% and 35.4%, respectively. The density of ground pest and rat hole after the control was 12 1 / m2 and 10. 6 / m2, and the control area was 14.3 / m2 and 12. 4 / m2. Applying Ketusin 1 to prevent and control forest trees caused by harmful rats significantly reduced the mortality rate, by analysis of variance, control and control areas significant difference. At the same time, we discussed the feeding method and feeding amount of different harmful rats.
