据植物学家的研究发现,荷的叶面密生细小的绒毛,覆盖有一层蜡质的粉,保护着叶面的气孔。当雨水滴在叶面上时,由于细小绒毛的推动,会形成滚来滚去的水珠。当污物或灰尘沾染叶面时,由于叶面上细小绒毛的作用,不易被沾附,且极易被水冲刷掉或被风刮走。现代环境科学又证明,莲藕独具一种解毒排污的“自净”能力,它可以过滤掉污泥浊水中的有害成分。莲藕在污染的环境里生长,能够吸收、转移和富集多种金属元素,使淤泥中的铁、锰、锌、 According to the botanist’s study, the tiny hairy foliage of the leaves of the Netherlands, covered with a layer of waxy flour, protects the leaf stomata. When the rain drops on the foliage, drops of water will form as the small fluff advances. When the dirt or dust contaminated leaves, due to the role of fine hair on the foliage, not easy to be stained, and easily washed away by the water or by the wind away. Modern environmental science has proved that lotus root has a unique detoxification sewage “self-purification” ability, it can filter out the harmful components of muddy water. Lotus root growth in the polluted environment, to absorb, transfer and enrichment of a variety of metal elements, the sludge of iron, manganese, zinc,
