绿色植物是空气天然的“净化器”。科学家们通过研究和实验证明,植物对空气中几种重要的污染物(CO2、SO2、HF、NH3、Cl2及汞蒸气等)具有很强的吸附能力,这些污梁物可通过绿色植物叶片背面的微孔道被吸入植物体内,而且花卉根部共生的微生物也能自动地分解污染物,并被根部吸收。比如芦荟、吊兰能在新陈代谢中把甲醛转化为橡糖或氨基酸那样的天然物质。 Green plants are natural “purifiers” of air. Scientists have proved through research and experiments that plants have a strong adsorption capacity for several important pollutants (CO2, SO2, HF, NH3, Cl2, mercury vapor, etc.) in the air. These pollutants can pass through the back of green plants. The microchannel is inhaled into the plant, and the symbiotic microorganisms in the flower root can also automatically decompose contaminants and be absorbed by the roots. For example, aloe vera and chrysanthemum can convert formaldehyde into natural substances such as sugar or amino acids in the metabolism.
