新编的生物第一册(上)中增加了《观察葫芦藓》实验内容。这节实验大约在12月左右做,但由于季节、环境污染等原因不易采到葫芦藓。为了方便教学,夏天,在葫芦藓成熟的季节,到郊外将成熟的葫芦藓采集下来,去掉泥土,把三至五根葫芦藓放在吸水纸上面再盖上几张吸水 The first experimental book (observing the observation of the gourd) was added to the first book of the new book (above). This section of the experiment was conducted around December, but due to seasonal and environmental pollution, it is not easy to pick gourds. In order to facilitate teaching, in the summer, in the ripe season of gourd, collect the mature gourd from the suburbs, remove the dirt, put three to five gourds on the absorbent paper and cover it with water.
