Beijing in March once again ushered in the decoration season. With the increase in awareness of environmental protection in home improvement, many families have chosen to put plants in a "detoxification" way, which also led to the sales of flowers. The reporter recently discovered that in some flower markets in the city, there was a phenomenon of playing the “purify air†brand.

A sticker can sell more than one percent
The reporter saw some flower markets in the city such as Laitai, Fornit and Laiguangying. Some merchants even posted signs for "purifying the air" and "excluding formaldehyde."
At a booth marked “Exclude Formaldehyde and Clean Airâ€, the sales staff told the reporter, “Since February, we have affixed the logo of 'purifying the air'. Not only are there more people consulted, but they are probably able to sell more than before. It's about.†He pointed to a pot of ivy and told reporters, don’t look for this pot as long as more than 20 yuan. In the day, he can sell 20 or 30 pots.
Before another stall, when it was learned that the purpose of the reporter’s purchase of flowers was, the sales staff said that most of the major sales here were plants that had an improving effect on the environment of the living room. He told reporters that in order to purify the air in the living room, it was better to select the leaves. Larger plants, and preferably no flowers.

Purification of indoor air-tolerant plants is effective
In an interview, the reporter found that some salespeople obviously lacked logic. For example, "If it is a 20-square-meter house, this pot can reduce formaldehyde by 20%. You can buy 5 pots without problems." A salesperson even Said, "I am not clear about the specific, anyway, are good for the room."
So how important is the flower to eliminate harmful gases in the room? Which plants are more suitable for placing in the living room? With these two questions, the reporter interviewed Dr. Zhao Shiwei, deputy head of the Beijing Botanical Garden.
"Plants have a certain effect on purifying indoor air and eliminating harmful components such as formaldehyde, but I personally feel that some of the current publicity has overestimated its actual role." Dr. Zhao Shiwei said that after all, plants are quite limited in their ability to breathe, relying entirely on plant removal. Unrealistic.
Which kind of plant is more able to purify indoor air is currently not conclusive. In contrast, negative-tolerance plants have a greater effect on purifying indoor air. The so-called negative resistance, that is, plant growth mainly depends on photosynthesis, and some negative-tolerance plants can grow better in the absence of photosynthesis. Therefore, it is said that plants that are suitable for indoor growth and have large leaves have stronger resistance to negative. The negative-tolerance plants include bamboo shoots, Araceae, Evergreen, Dracaena, and other varieties.
In addition, there are some misunderstandings in the introduction of plant functions in the market. For example, cactus plants such as Jinhu are relatively more in need of sunlight. There is no problem in beautifying the indoor environment, but it is not very good for decontamination. Dr. Zhao Shiwei also emphasized that some of the so-called toxic plants, including tiger acacia, oleander and green radish, are actually very good indoor shade-tolerant plants. As long as they do not eat it or touch it, there is no problem.
He also stated that in addition to purifying the air, flowers and plants also have a certain improvement on the environment of the living room. On the one hand, it will emit some water itself, which will increase the humidity in the room, and on the other hand, it will also be beneficial to people's spiritual adjustment. .
