摘要
鼠害逐渐成为林业危害之一。以中坝乡、蒲台乡作为防治实验点,选择林地类型有灌木林地、宜林地、有林地3类立地各8个,采用物理防治和化学防治作为对比开展除治,结果表明:以采用雷公藤甲素0.25 mg/kg颗粒剂化学防治效果较好。每个样地的平均捕获数为为25.83个,从三类林地类型来看,宜林地密度最大,灌木林地次之,有林地最小。三者间的数量关系接近3∶2∶1。
Mouse damage has gradually become one of the forestry hazards.Zhongba township,Putai township are taken as the control experimental point.8 sites of shrub land,suitable forest land and forest land were selected,and physical control and chemical control were used as control.The results showed that the chemical control effect of Triptolide 0.25 mg/Kg granules was better.The average capture number of each sample plot was 25.83.According to the three types of forest land,the density of suitable forest land was the largest,followed by shrub land and forest land.The quantitative relationship among the three is close to 3∶2∶1.
