人们在长期的生产实践中观察发现,在千姿百态的植物界中,有些植物能在天气变化之前表现出特有的反应,以预示天晴或阴雨,因而被誉为植物界的“气象预报员”。树叶无风摆动梧桐、杨树等在夏日无风的情况下,有时会有少数叶片摇来摆去,经久不停。这种现象预示着将在一、两天内降雨。含羞草“害羞”你用手触动一下含羞草,倘若它的叶子很快合拢,瑟瑟地垂下头,并经相当长时间才恢复原态,那么,就可以发出预报:当日天气艳阳高照,晴空万里。反之,若触动它,叶子收缩慢,下垂迟缓,或叶子
It has been observed in long-term production practice that in plants with different poses and in different attitudes, some plants exhibit a peculiar reaction before the weather changes to indicate the weather is sunny or rainy, thus becoming the “forecasters” of the plant kingdom. Leafless wind swing Indus, poplar, etc. In the summer without wind, sometimes there will be a few leaves shaking, prolonged non-stop. This phenomenon indicates that it will rain in one or two days.
