Generally, potted plants or hydroponics are placed indoors in sunny places ~ Chrysanthemum: It can resist and absorb harmful gases such as ethylene, mercury and lead emitted by household appliances and plastic products in the air, but it has strong resistance to sulfur dioxide, hydrogen chloride and hydrogen fluoride. Can be potted ~ cactus and succulents: the stomata on the fleshy path of cactus and succulents are closed during the day and opened at night, so they can absorb carbon dioxide at night. It releases oxygen, so it can increase fresh air and negative ions. It can also reduce the harm of electromagnetic radiation to human body and has a good inhibitory effect on bacteria in the air. But it is speculated that cactus can also remove volatile organic compounds. Can be placed on the balcony, courtyard, windowsill, desk or computer desk ~ big gray gray orchid: Orchidaceae plants can absorb carbon monoxide and formaldehyde in the air. It can purify the air. Should be placed in a well-ventilated, semi-cool, cold-proof place, such as the living room on the windowsill ~ Aloe: it can purify harmful and toxic gases such as formaldehyde, carbon dioxide, sulfur dioxide and carbon monoxide. In the air, especially the absorption of formaldehyde is particularly strong. When the toxic gas is serious, brown spots will appear on its leaves, which plays a warning role. Under the condition of 4 hours illumination, a pot of aloe can eliminate 90% formaldehyde in one cubic meter of air. It can also kill harmful microorganisms in the air and absorb dust, which plays a great role in the elite living room environment. Put it in a place without strong direct sunlight ~ Cycas: Purify harmful gases such as carbon dioxide, nitrogen peroxide, ethylene, mercury vapor, fluorine and lead vapor in the air. You can put it in the yard. Or make bonsai for viewing. Chlorophytum: It can absorb harmful gases through photosynthesis under weak light, especially 95% carbon monoxide and 85% formaldehyde in the air. Chlorophytum can also decompose benzene harmful substances emitted by photocopiers. In addition, it can absorb nicotine in tobacco leaves. Can be placed in windowsill, balcony, bedroom, living room, study and other places ~ Ivy: can absorb toxic benzene, with 24-hour lighting. It can absorb 90% benzene indoors. It can also adsorb particulate dust and purify the air. Can be hung indoors ~ Huweilan: it has a strong function of absorbing formaldehyde. According to records, two pots of medium-sized Euonymus japonicus can effectively absorb the toxic substances released by formaldehyde in a room of about 15 square meters. It should be placed in a bright and ventilated room, such as living room, bedroom and study room. Computer room ~ cold spray: it can purify the oil fume emitted by cooking in the kitchen and is an ideal environmental protection plant in the kitchen. Put it in dark places indoors, such as kitchen, bathroom, living room, bedroom, etc. , and has a strong resistance to negative palm: absorption of chlorine, sulfur dioxide, hydrogen fluoride, mercury vapor and so on. , especially chlorine and sulfur. Kilogram of dry leaves can absorb 65,438+sulfur. Tortoise shell bamboo in the living room and other places: remove the harmful substance formaldehyde in the air and put it in indoor corridors and other places ~ Clivia: it has a very advanced absorption effect on hydrogen sulfide, carbon monoxide and carbon dioxide, and can also absorb smoke and adjust the turbid indoor air, so it can be placed in the living room instead of the bedroom ~ Fortune tree: it is one of the international environmental protection tree species recommended by the United Nations. Can effectively purify the surrounding air, especially for carbon monoxide, ammonia and carbon dioxide. Can be placed in the living room, corridors and other places ~ Haitang: It has strong resistance and absorption ability to sulfur dioxide. Placed on balconies, courtyards, windowsills, etc. ~ Chimonanthus praecox: It can absorb mercury vapor, purify harmful substances such as sulfur dioxide, and remove harmful substances emitted by household appliances and plastic products in the air. Can be placed on the balcony, roof garden, etc. ~ kumquat: it can purify harmful substances such as mercury vapor, lead vapor, ethylene and nitrogen peroxide in the air, and absorb the odor and resistance of household appliances and plastic products in the air. Indoor viewing ~ Rose: It can adsorb harmful substances such as benzene, hydrogen sulfide and hydrogen fluoride in the air, as well as ether, nitrogen dioxide and chlorine, which has a good effect on purifying the air. Potted plants can be placed in terraces, living rooms and other places ~ Camellia: It can absorb sulfur dioxide, hydrogen fluoride, chlorine, hydrogen sulfide and nitrogen, and can be placed in sunny places such as terraces, roof gardens and window sills. In addition, it can absorb carbon dioxide and hydrogen fluoride to some extent. Can be placed in dark places such as bedroom and living room corner ~ geranium: it can absorb chlorine in the air and resist sulfur dioxide and hydrogen fluoride. It can be planted in the courtyard or potted in the verandah and hall ~ Rubber tree: it can resist harmful substances such as formaldehyde, carbon monoxide, carbon dioxide and hydrogen fluoride in the air to a certain extent, and can play a role in retaining indoor dust. Can be placed in indoor living rooms, corridors and other places ~ azaleas: azaleas have strong resistance to harmful gases such as ozone and sulfur dioxide, and can also absorb these harmful gases and purify the air. It is also very sensitive to ammonia and can be used to monitor plants. Can be placed on the balcony, roof garden, windowsill ~ Begonia: Begonia can remove harmful substances such as hydrogen fluoride from the air, and is also very sensitive to nitrogen oxides, which can be used as a monitoring indicator plant. Once these harmful gases are in the air, the leaves will appear spots and even wither. Can be placed indoors or on the balcony ~ Plum Blossom: Plum Blossom can monitor formaldehyde, hydrogen fluoride, benzene and sulfur dichloride. After it was attacked by poisonous gas, its leaves were damaged and mottled, so it is a good monitoring plant. Can be placed on the balcony, windowsill, living room, etc. Peony: Peony is very sensitive to light, smoke and fog pollution in the atmosphere, such as sulfur dichloride. Once this kind of pollution occurs, according to the pollution degree, several spots with different colors can appear on the leaves, which plays an indicating role in monitoring the pollution degree. Can be placed on the balcony, balcony, roof garden and other places ~ pay special attention! Most of the above plants should not be placed in the bedroom ~ because most plants carry out photosynthesis during the day, absorb carbon dioxide and release oxygen; Breathe in oxygen at night and release carbon dioxide. In other words, it will rob the room of oxygen. Therefore, we can refer to the following standards in the selection of bedroom plants: 1, chlorophytum 2, cactus, fairy mountain, cactus, etc. 3, swallow palm, Yu Lian, Shi Lian, etc. 4.
