1、灭螺有机复合肥料的灭螺效果观察及预防意义詹素云欧阳俊杰(宜春学院医学院,江西省宜春市336000)摘要:目的:观察灭螺有机复合肥料的灭螺效果,探讨其预防血吸虫病的意义。方法:分2个实验组:灭螺有机复合肥1,灭螺有机复合肥2。5个对照纽.:氯硝柳胺、渙乙酰胺、有机复合肥1、有机复合肥2及淸水。将活成螺装入尼龙布袋(每袋20只),每种浓度4袋,清水、有机复合肥1、有机复合肥2各4袋,浸泡Id、2d、3d、4d、各取1袋,用清水冲洗干净,经2d恢复期饲养,最后用敲打法鉴定死活。结果:灭螺有机复合肥料1X10"浸杀4d、2X106浸杀3d、钉螺死亡率达100%。而氯硝柳胺及混乙酰胺2X10&
2、浸杀4d、4X1(T浸杀4d、8X10"浸杀3d钉螺死亡率才达100%。在相同时间内,灭螺有机复合肥料的4种浓度的灭螺率,分别比单纯氯硝柳胺、漠乙酰胺4种浓度的灭螺率高。在相同时间内,灭螺有机复合肥料的4种浓度的灭螺率,分别与有机复合肥1、有机复合肥2比较,差异均有显著性(P均<0.001)o结论:灭螺有机复合肥料有显著的灭螺效果。关键词:灭螺有机复合肥料;有机复合肥料;灭螺药;灭螺效杲;观察中图分类号:R184.6文献标志码:AAnObservatiorioftheMolIuseicidaIEffectoftheMolluscicidalOrganicCompoundFertiIi
