What are the functions of the latest hanging orchids?

Hanging orchids are not only shaped like orchids and bright green in the four seasons, but also have a strong ability to absorb pollution. "the family grows hanging orchids, but the dirty ghosts are scared." people in southern Fujian, Taiwan and other places praise hanging orchids in this way. Cymbidium is the best plant to purify indoor air, which has been approved by scientists. Bill Warwell, an American environmental expert, once conducted an experiment. He put the orchid in a special plexiglass container, gave it good light, and then filled it into the air in the polluted room. After a period of time, the air composition absorbed by the orchid was measured. It was found that there was little harmful gas left in the container, and its efficiency almost exceeded that of the air filter.

The hanging orchid can absorb and purify all the harmful gases in the experimental container within 24 hours. As long as a pot of orchids is put in the dormitory, harmful gases such as carbon monoxide and nitrogen peroxide emitted by indoor electrical appliances, stoves, plastic products and paints can be absorbed and transported to the roots within one day, and then decomposed into harmless substances by microorganisms in the soil, which are absorbed as nutrients.

In its own metabolism, Cymbidium can also convert the carcinogenic formaldehyde in the air into sugars and amino acids. And can decompose the benzene emitted by photocopiers and printers, but also "swallow" nicotine and so on. Therefore, in a room of about 10 square meters, as long as there is a pot of orchids, it is equivalent to installing an air purifier, which is enough to offset the negative effects of harmful gases.

Scientists also put several pots of orchids in a closed environment such as the airtight capsule of the space shuttle, and 12 hours later, harmful gases such as carbon monoxide, nitrous oxide and formaldehyde were reduced by 85%. Researchers at Xi'an Botanical Garden say that in recent years, more and more people have chosen Cymbidium as a family potted plant, and its pollution-absorbing ability has been recognized by most people.

In addition, hanging orchid is also often used indoors, especially the indoor "negative ion" purifier after decoration, which is believed to have an obvious effect on reducing the concentration of harmful substances such as formaldehyde and benzene.
