蛇形毒饵站的稻田防治效果试验

为了确定自主研发的蛇形管毒饵站的使用效果,于2007年7月在哈尔滨市民主乡高玉环屯水稻田进行了田间防治试验。结果表明:在处理样地中的毒饵站平均毒饵消耗量的下降趋势符合y=5.169 3e-0.0685x,R2=0.984 5;在对照中平均饵料消耗量增长趋势符合y=1.820 7e0.027x,R2=0.966 7。说明在处理样地中的毒饵消耗随着害鼠数量的减少而逐渐减少,对照样地中害鼠对毒饵站中的饵料选择性增加,使饵料的消耗量逐渐增加。夹夜结果为处理平均捕获率为2%,对照平均捕获率为11.33%,防治率为82.35%,防治效果明显。

Effect of Serpentine Tube Poisonous Bait in Rice Field

In order to test the serpentine tube poisonous bait station which autonomous innovative by ourselves,it was tested it in rice field experiment in Harbin Minzhu townships Gao Yuhuan village in July 2007.The results showed that consumption averaged poison bait with poison accord with the decreasing function：y=5.169 3e-0.0685x,R2 =0.984 5,and consumption averaged poison bait with no poison plot accord with the increase function y =1.820 7e0.027x,R2 =0.966 7.It is shown that poison bait consumption reduced because of the number of rodents decreased in the treatment plot,and poison bait consumption increased because of rodents selectivity increasing in the control plot.The results of the night traps showed that the average capture rate was 2% in the treatment plot,the average capture rate was 11.33% in the control plot,the effect of prevention and cure was 82.35%.
