为寻找适合长江江滩的灭螺方法，压缩钉螺面积，于1995年5月在洪山区天兴乡进行了氯硝柳胺乙醇胺盐可湿性粉剂土埋缓释灭螺研究。通过对2g／m2、4g／m2土埋缓释和2g／m2、4g／m2机喷两种灭螺方法对比观察，结果显示：灭后15d两种灭螺方法的效果相仿，其钉螺校正死亡率均在91％以上；灭后30d，缓释4g／m2剂量组活螺密度下降率为98.42％，活螺框减少率为94.16％，钉螺校正死亡率为97.25％，其效果优于缓释2g／m2及机喷2g／m2、4g／m2剂量组；灭后180d的远期效果亦以缓释4g／m2剂量组最佳，3项指标分别为93．99％、91．92％和95．31％。此法操作简便，其费用仅为机喷的1／3，适合于大面积长江江滩应用。
In order to find a snail-killing method suitable for the Yangtze River beach and compress the snail area, a slow release and snail-killing study of niclosamide ethanolamine wettable powder was carried out in Tianxing Township, Hongshan District in May 1995. By 2g / m2, 4g / m2 soil burial slow release and 2g / m2, 4g / m2 machine spray two kinds of snail control method comparison, the results showed that: 15d off after the two kinds of snail-killing methods similar effect, the snail corrected death The rate of living snail densities was 98.42%, the percentage reduction of live snails was 94.16% and the corrected mortality of snails was 97.25%, which was better than sustained release 2g / m2 and machine spray 2g / m2, 4g / m2 dose group; the long-term effect of 180d after extinction is also the best in the sustained release 4g / m2 dose group, the three indicators were 93.99%, 91.92% 95.31%. This method is easy to operate, the cost is only one-third of the machine spray, suitable for large areas of the Yangtze River beach applications.
