Pest control of Cymbidium is often checked and fertilized frequently.

Plants absorb formaldehyde and purify the air, which is a method with few natural side effects, so it is accepted by many families. Among the few plants with this function, Cymbidium is one of them, and attracts more families to introduce it indoors because of its stronger ornamental. So, how effective is it when the orchid absorbs formaldehyde?

The hanging orchid gets the laudatory name of the air purifier, which is related to the characteristics of the hanging orchid.

1. Cymbidium, which can carry out photosynthesis in weak light, can absorb more than 80% of the harmful gases in the room, and has a strong ability to absorb formaldehyde. General room raises 1-2 basin hanging orchid, the poisonous gas in the air can be absorbed completely, a basin hanging orchid is in the room of 8-10 square meters, be equivalent to an air purifier.

2. The experiment shows that 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. Therefore, the hanging orchid is also known as the "green purifier".

3. In its own metabolism, Cymbidium can also convert the carcinogenic formaldehyde in the air into sugars and amino acids.

4. Due to the continuous release of harmful gases such as formaldehyde in the newly renovated house, environmental protection experts suggest that after decoration, keep more ventilation and raise a few pots of hanging orchids and other green plants, so that the new house can basically meet the occupancy standard after three to six months.

Cymbidium is the best plant to purify indoor air, which has been approved by scientists. Bill, an American expert on environmental issues. Warwell once conducted an experiment in which he put the orchid in a special plexiglass container, gave it good light, then filled it into the air of the polluted room, and then measured the air composition absorbed by the orchid over a period of time. There is little harmful gas left in the container, which is almost more efficient than the air screening program.

Although the orchid has a strong ability to absorb formaldehyde, and this is also supported by experimental data, we should also be soberly aware that its capacity is limited after all, and we should not exaggerate this ability excessively, otherwise it will greatly reduce the process of air purification. This may be the reason why many materials emphasize the size of space, and why environmental experts not only recommend hanging orchids, but also put ventilation in the first place, but also emphasize the importance of time.
