那是1771年,距今已经200多年了。有一个名叫波斯特莱的外国人做了一个实验,他在玻璃瓶中点燃了一支蜡烛,盖上瓶盖,等蜡烛完全熄灭以后,把一小枝薄荷放到瓶里,再盖好瓶盖,在日光下放10天左右,再把点燃的蜡烛放到瓶里,蜡烛又能继续燃烧。这个实验证明了植物有“恢复空气”(产生氧气)的能力。这是研究光合作用的开始。从这以后,研究光合作用的越来越多。现在, It was 1771, more than 200 years ago. There was an experiment by a foreigner named Poststreet who lit a candle in a glass bottle and put the cap on it. After the candle had completely extinguished, put a sprig of mint in the bottle and the bottle was closed Cover, put in daylight for about 10 days, then put the lit candle into the bottle, the candle can continue to burn. This experiment demonstrates the plant’s ability to “rejuvenate the air” (producing oxygen). This is the beginning of the study of photosynthesis. Since then, more and more photosynthesis research. just now,
