| 摘 要： | 用枫杨的新鲜叶、茎皮、根皮水浸液处理钉螺的周年实验表明；枫杨水浸液对钉的毒杀作用随处理液浓度的增加和处理时间的延长而增大；毒杀作用的大小具有的季节性差异，夏季毒杀效果最好，春，秋季次之，冬季毒杀效果差，枫杨各部位之间灭钉螺作用大小也随季节更替而变化。

| Abstract: | The result of annual experiment in which Oncomelania was treated with the soaking liquid of Pterocarya stenoptera's fresh foot or bark or leaf in water showed that as the density of soaking liquid is raised or the time of treating is lasted, the mortality of Oncomelania has also come up;furthermore ,the soaking liquid of Pterocarya stenoptera has different effects of killing Oncomelania in different seasons It is the strongest in summer,the stronger in spring or autumn and the weakest in winter |
