摘　　要：目的探索适合山丘地区的灭螺方法。方法采用单纯灭螺法、复合灭螺法和改良灭螺法分别对1000 m2的有螺面积进行灭螺,比较3种灭螺方法的用工投入和1年后的灭螺效果,并于2006年和2007年采用改良灭螺法进行了扩大灭螺试验。结果单纯灭螺法、复合灭螺法和改良灭螺法的用工投入分别为1.5、75工和22工;1年后有螺面积压缩率分别为25%、100%和100%;改良灭螺法扩大灭螺有螺面积压缩率为96.48%,以往单纯灭螺法的灭螺效果为36.47%,改良灭螺法的灭螺效果比单纯灭螺法提高了164.54%。结论单纯灭螺法因效果差而不可取;复合灭螺法投入大,且易损坏农田设施,很难广泛应用;改良灭螺法投入适中,简单易行,效果理想,可广泛应用于山丘地区灭螺。The simple molluscicide-using method, excessive molluscicide-using method and improved molluscicide-using method were used to control Oncomelania snails in an area of 1 000 m^2, respectively, so as to explore the suitable technologic methods of molluscicides in hilly regions. The results showed that the simple molluscicide-using method should not be encouraged because of its bad effect, the excessive molluscicide-using method also should not be popularized because of its large expense and damages to the farmland, but the improved molluscicides-using method was suitable in the hilly areas as its low input, easy operation and good effect.
