目的：观察单纯黑色地膜覆盖法在云南山区的灭螺效果，为推广其使用提供科学依据。方法选择南涧县乐秋村的有螺梯田，按从上到下的顺序分成A、B、C、D、E5组，其中A、B、C、D4组为实验组，实施单纯黑色地膜覆盖灭螺，覆膜时间分别为30、60、90 d和120 d；E组为对照组，采用50%氯硝柳胺乙醇胺盐可湿性粉剂喷洒灭螺，比较两种方法的灭螺效果与成本。结果单纯黑色地膜覆盖法覆膜90 d和120 d后，覆膜区域均未查到钉螺，活螺平均密度与灭螺前相比下降100%，1年的灭螺成本不高于对照组。结论单纯黑色地膜覆盖法灭螺效果较好，可在不宜开展药物灭螺地区推广应用。

Objective To evaluate the molluscicidal effect of black plastic mulching in mountainous areas of Yunnan Prov-ince. Methods In Leqiu Village,Nanjian County,Yunnan Province,the terraced fields with Oncomelania hupensis snails were divided into A,B,C,D,E groups,and of which,A,B,C,D groups,as the experimental groups,were administered with sim-ple black plastic mulching for 30 days,60 days,90 days and 120 days respectively;Group E,as the control group,was adminis-tered with 50%niclosamide ethanolamine salt wettable powder spraying. Results In Group C and D(simple black film mulching for 90 days and 120 days),no snails were found after the administration,the average density of living snails decreased by 100%, and the cost of one year was similar to that of the control group. Conclusion The molluscicidal effect of black plastic mulching is good in mountainous areas.
