青蛙是“捕虫能手”,已是众所周知的事。但对青蛙吞食哪些农林害虫,每天吞食的有效系数是多少,却缺少充分的数据。为此,我校从1984年起在青蛙解剖实验中,同时对青蛙胃进行解剖和食性分析的统计。这既可以增强学生对保护青蛙的自觉性,也为学生的科技活动作一些基础训练。现将实验过程和有关数据介绍如下: It is a well-known fact that frogs are “catching insects”. However, what are the effective coefficients of swallowed daily for the frogs, but lack sufficient data? To this end, our school from 1984 frog anatomy experiment, at the same time the frog stomach anatomy and diet analysis statistics. This will not only enhance students’ awareness of protecting frogs, but also provide some basic training for students in science and technology activities. Now the experimental process and related data are as follows:
