土埋灭螺是山丘地区灭螺方法之一 ,但在石头较多的有螺环境 ,若采用土埋灭螺法 ,土埋厚度难以达到技术要求 ,且有钉螺沿压实不紧的缝隙上爬的可能 ,螺情的反复性较大。因此 ,我们首次采用薄膜覆盖灭螺法进行了现场试验 ,以探求更加有效的灭螺方法 ,现将试验结果报告如下 :1　材 Soil burying snail is one of the snail-killing methods in the hill area. However, in the snail environment with more stones, if the soil embedding snail method is adopted, the thickness of the burying soil is hard to meet the technical requirements and the snail snaps along the compaction gap Climbing may be more repetitive snail. Therefore, for the first time, we conducted a field test with the membrane-covered molluscicide method to find out more effective molluscicidal methods. The test results are reported as follows: 1
