为了获得在冬季讲课时进行光合作用实验的较合适的材料,本人曾在1954和1955年两个冬季选取了多种在田野中生长良好的植物进行了反复的实验。试验结果,认为最满意的材料是小白菜和羊蹄(一种蓼科植物属酸模属。这两种材料有如下优点:(1)无需温室培养,至少在长江流域地区的任何中学都可以取得这种材料。(2)光合作用进行迅速,
In order to obtain a more appropriate material for photosynthesis experiments during winter lectures, I conducted a series of experiments over the course of winter in 1954 and 1955 by selecting a number of plants that grew well in the fields. According to the results of the experiment, the most satisfactory materials are cabbage and sheep hoof (a polygonaceae belonging to the genus Acidophilus, which has the following advantages: (1) it is possible to obtain this material at least in any middle school in the Yangtze River Basin without greenhouse cultivation Materials (2) Photosynthesis is rapid,
