新编高中《生物》（上海版）实验三，需要顾藻作实验材料。这种材料在室外采集不太方便，采到的颤藻纯度较低，分离困难，不利于学生识别观察。我们在实践中摸索到利用实验室的水泥水斗养殖额藻的方法。此法简便易行，养殖出来的颤藻纯度高，可随时采用，十分方便。现简介如下 The third experiment of the new high school “Biology” (Shanghai edition) requires Guzao as experimental material. This kind of material is not convenient for outdoor collection, and the collected vibroseis is of low purity and difficult to separate, which is not conducive to student identification and observation. In practice, we explored ways to use the laboratory’s cement buckets to culture the amount of algae. This method is simple and easy, and the cultured algae has high purity and can be used at any time. It is very convenient. The brief introduction is as follows
