世双鼠靶防治不同林分内棕背?效果研究

The Control Effect of Sishuangshuba on Clethrionomys rufocanus in Diffrent Stands

世双鼠靶在4种不同幼林林分中撒施10d后平均防治效果达到65.42%,且不同林分之间具有显著差异性。其中,防治效果最好的是云杉幼林,最差的是落叶松幼林,两者之间差异极显著。分析原因是世双鼠靶在不同林地内野外摄食系数不同导致。总体来说,世双鼠靶作为环保型药剂在木兰林区防治棕背?鼠害效果较好,可推广应用于广大林区棕背?鼠害防控。

The average control effect of Shishuangmu target was 65.42%after 10 days of spraying in four different stand of Young,and there were significant differences among different stands,among which there were highly significant differences between the best Control Effect of Young Picea asperata and the worst Control Effect of Young Larix principis-rupprechtii.The reason of significant differences among 4 different stands may bedifferent Ingestion coefficient in different stands.In general,the invirnmental rodenticide named Shishuangshubahad a good control effect of Clethrionomys rufocanus in Mulan forest area,It had populariztion and application value for control Clethrionomys rufocanus in forest managenment.
