摘　　要：目的观察碳酰胺结合黑色地膜覆盖杀螺效果。方法选择金华市江东镇曾有钉螺孳生的潮湿荒田,设加药黑色地膜组、黑色地膜组和空白对照3个组进行灭螺试验。结果试验第3、7、15、20 d和30 d加药黑色地膜组钉螺死亡率分别为86.0%、88.0%、100%、100%、100%,均高于对照组,差异均有统计学意义;在第3、7 d高于黑色地膜组,差异均有统计学意义。结论喷洒碳酰胺显著提高了黑色地膜覆盖灭螺效果,该法操作简便,是一种理想的灭螺方法。Objective To evaluate the molluscicidal effect of black plastic film combined with carbon amide. Methods In Jiangdong Town, Jinhua City, the field with Oncomelania hupensis in the history was selected as experimental area and divided into 3 groups： Group One was administered with black plastic film combined with carbon amide; Group Two was administered with simple black plastic film; and Group Three was a control group. Results On the 3rd, 7th, 15th, 20th and 30th day after the experiment, the mortality rates of O. hupensis of Group One were 86.0%, 88.0%, 100%, 100% and 100% respectively, which were significantly higher than those of the control group （all P 〈 0.05）. The differences of mortality rates between Group One and Group Two were statistically significant on the 3rd and 7th day after the experiment （Group One was superior to Group Two）. Conclusion The black plastic film combined with carbon amide can improve the molluscicidal effect.
