摘要: 为了获得广东蕉岭县福寿螺分布和危害情况基础数据,为推广具有环境友好生态功能的植物源杀螺剂油茶粕提供依据,于2015年6月至2016年4月以问卷调查、访问农技部门调查和野外现场调查的方式搜集福寿螺危害和防治措施数据。结果发现蕉岭地区各镇福寿螺危害严重,单位面积可捡福寿螺的数量均在20只/m2以上,可捡福寿螺至少为767.05 kg/hm2,最多可达1227.28 kg/hm2;水稻分蘖前期大中螺的比例几乎均超过50%,各镇投入防治福寿螺的经济成本仅占福寿螺造成损失的5%左右;有67.09%的农户使用农药灭螺。在水稻分蘖前期推广应用植物源杀螺剂油茶粕与肥料混施具有较高的经济价值和生态价值。

Abstract: The aims of the study are to obtain the basic data of Pomacea canaliculata distribution and harm condition in Jiaoling County, Guangdong Province, and provide foundation for popularizing environment friendly molluscicide oil- tea meal. The data were collected by questionnaire investigation, agricultural department survey and field survey from June 2015 to April 2016. The results showed that there was serious harm by Pomacea canaliculata in Jiaoling County, the quantity and weight density of Pomacea canaliculata was 20 ind./m2 and 767.05 kg/hm2, respectively, and the largest weight density was up to 1227.28 kg/hm2. Large and medium Pomacea canaliculata exceeded 50% in early tillering stage of rice. The cost for controlling Pomacea canaliculata only occupied 5% of the loss caused by it. 67.09% farmers used pesticides to control Pomacea canaliculata. Thus, in the early tillering stage of rice, the mixed application of plant source molluscicide oil- tea meal and fertilizer might have a high economic and ecological value for controlling Pomacea canaliculata.
