植物生长和人一样需要吃东西,但它们要吃的是些什么,很早以前的人们并不十分清楚。古希腊的科学家亚里士多德认为植物是靠吃土壤中的营养成长的,可是后来比利时科学家范·海尔蒙通过多次实验,却说植物完全是靠喝水长大的。 Plant growth needs to be eaten as much as human beings, but what they eat is what people did not know very well before. Aristotle, an ancient Greek scientist, believed that plants rely on the nutrient growth in the soil, but after many experiments by the Belgian scientist Van Helmont, they said that the plants grew up entirely by drinking water.
