动物学实验有一个重要特点,它的实验对象是活的有机体,必须在实验前加以采集和培养。现将一般常用的无脊椎动物实验材料的采集、处理和保存方法介绍如下。1 标本的采集 要根据动物的栖息环境,在一定的时期内进行采集。例如采集蜗牛,可在墙角潮湿的地方;采集昆虫,最好在晚春至秋末;采集蚯蚓,宜在温暖和下雨的晚上,在其排泄物的土堆内掘取。
The zoology experiment has an important feature. Its experimental object is a living organism that must be collected and cultivated before the experiment. The collection, processing, and preservation methods for commonly used invertebrate experimental materials are described below. 1 Collection of specimens Collection should be performed within a certain period of time according to the habitat of the animal. For example, snails can be collected in wet corners; insects should be collected, preferably from late spring to late autumn; collecting cockroaches should be carried out in the earth piles of their excrements on warm and rainy evenings.
