不同投饵量对草地高原鼠兔有效洞口减退率的影响

EFFECT OF DIFFERENT BAITS QUANTITY FOR CONTROLLING RODENTS IN GRASSLAND

用C型肉毒素、燕麦配制成毒饵的不同投饵量,即A,0.45kg/hm2(8粒/洞)、B,0.56kg/hm2/(10粒/洞)、C,0.87kg/hm2(15粒/洞)和D,1.29kg/hm2(20粒/洞)对高寒草甸类草地高原鼠兔进行了防治试验。结果表明,C、D处理灭洞率最佳,分别达到93.5%和94.78%,经方差分析比较,两者间差异不显著。但C处理较D处理节省饵料0.2948kg/hm2,可降低投资成本0.58元/hm2。

Trial on controlling rodents were carried out by using botulinus. C toxic baits in different quantity ： A： 0. 45kg/（ ha） （8 granule/hole）, B： A： 0. 56kg/（ ha） （10 granule/hole）, C： 0. 87kg/（ ha） （15 granule/hole） ,D： 1.29 kg/（ha） （20granule/hole）, the results showed that C treatment and D treatment effect were the best, each could reach 93.5% and 94.78%, from variance analysis , difference wasnt obvious Saving baits 0. 2948 kg/（ha） and reducing the cast 0.58 RMB/（ha） of C treatment than D treatment.
