目的　解决太湖芦滩灭螺与水产养殖的矛盾。方法　生石灰撒粉加土埋方法在现场实验 ,采用生石灰剂量 5 0 0、10 0 0 g/ m2 ,同时与氯硝柳胺喷洒加土埋和单纯土埋方法作对比。结果　两种生石灰撒粉加土埋 10、30 d后 ,与氯硝柳胺喷洒加土埋和单纯土埋的灭螺效果比较差异有显著性。结论　生石灰撒粉加土埋对太湖芦滩的灭螺效果较好 ,且可节省费用 ,对水产养殖无不良影响。 Aim To solve the contradiction between Lushan snail and aquaculture in Taihu Lake. Methods Lime dusting and soil-burial method were used in the field experiment. The dosage of quick lime was 500, 100, 000 g / m2, and compared with spraying with niclosamide and soil burial. Results After two kinds of lime were dusted and dug for 10-30 days, there were significant differences between the two kinds of quicklime and the snail control effect of niclosamide sprayed with or without soil burial. Conclusions The quick-lime-dredging and soil-burying is better than snail-killing in Taihu Lake, and it can save the cost and has no adverse effect on aquaculture.
