People will feel suffocated in a stuffy room. The reason is not the lack of indoor oxygen, but the lack of negative oxygen ions. When there is a TV or computer running indoors, negative oxygen ions will decrease rapidly. There are many plants that can be planted indoors that can produce negative oxygen ions-these plants are cypress, arborvitae and cedar.
If the indoor area is too small, you might as well change varieties and plant some low plants, such as cactus. At present, spruce and other low conifers are popular in the west, which can make the room full of refreshing tree fragrance.
Placing some anti-pollution flowers and plants in the living room can also play the role of an air purifier. For example, ivy can "eat" benzene, chlorophytum can "swallow" indoor carbon monoxide and formaldehyde, and bracts of Araceae can absorb benzene and trichloroethylene. 10 square meter room is good for air purification if there are anti-pollution plants.
Plants that can absorb toxic chemicals.
Aloe, chlorophytum, Eupatorium odoratum, Eupatorium odoratum and Dendrocalamus giganteum are natural scavengers, which can remove harmful substances in the air. Studies show that Eupatorium adenophorum and Eupatorium adenophorum can absorb more than 80% of indoor harmful gases, and their ability to absorb formaldehyde is super strong. Aloe vera is also a good hand at absorbing formaldehyde, which can absorb 90% formaldehyde contained in 1 m3 air.
Ivy, cycad, chrysanthemum, kumquat, pomegranate, Scutellaria barbata, rose, camellia, pomegranate, Milan, daisy, Chimonanthus praecox, marigold, etc. can effectively remove harmful substances such as sulfur dioxide, chlorine, ether, ethylene, carbon monoxide and nitrogen peroxide.
Orchids, osmanthus fragrans, wintersweet, cauliflower taro and osmanthus fragrans are natural dust collectors, and their cilia can intercept and absorb suspended particles and smoke in the air.
Plants that can kill bacteria
Volatile oil produced by fragrant flowers such as rose, osmanthus fragrans, violet, jasmine, lemon, rose, carnation, lily of the valley and crape myrtle. Has obvious sterilization effect.
Crape myrtle, jasmine, lemon and other plants can kill diphtheria, dysentery bacteria and other protobacteria within 5 minutes. The scents of roses, carnations, lilies of the valley, violets, roses, osmanthus flowers and other plants have obvious inhibitory effects on the growth and reproduction of mycobacterium tuberculosis, pneumococcus and staphylococcus.
Cactus and other succulent plants originated in tropical arid areas, the stomata on their succulent stems are closed during the day and opened at night, which absorbs carbon dioxide and produces oxygen at the same time, increasing the concentration of negative ions in indoor air.
Plants such as Hupilan, Huweilan, Tequila, Palm, Kale, Sedum, Rooting and Pineapple can also purify the night air.
Climbing plants such as Parthenocissus tricuspidata, grape, morning glory, wisteria, rose, etc. Planting around the house can make it climb along the wall or along the shelf to form a green arbor, which can effectively reduce sunlight radiation and greatly reduce the indoor temperature.
Lilac, jasmine, rose, violet, mint and other plants can make people relax, feel happy, help sleep and improve work efficiency.
Many people like to raise flowers indoors to improve and beautify the indoor environment, but if they choose it improperly, it will cause indoor pollution. Therefore, flowers should be paid attention to:
Choose a good variety. It is most suitable to choose evergreen flowers and trees or varieties that can absorb toxic gases, such as chlorophytum, asparagus, evergreen, cactus, tortoise shell bamboo, ivy and so on.
Unfavorable cloves and cordate telosma will emit particles that stimulate the sense of smell at night, which has adverse effects on patients with hypertension and heart disease; The floral fragrance of oleander can make people sleepy and decrease their intelligence; The particles emitted by hydrangea will make people's skin allergic and itchy; Tulip flowers are toxic and alkaline, and too much contact can easily make people's hair fall off; The oily smell of pine and cypress flowers and trees will affect people's appetite.
If you don't keep the flowers of "Fragrant Family" together with mignonette, mignonette will wither, but mignonette will release a substance to poison the rose and die before it withers. Young corn poppy, orchids, carnations, violets and lilies are difficult to get along with other flowers, leading to plant death.
Fungal spores produced by soil in flowerpots without flowers in patients' rooms will spread into indoor air, causing surface or deep infection of human body, and may also invade human skin, respiratory tract, external auditory canal, meninges and brain. Professor Li Zuowen, head of the expert group of Liaoning Landscape Architecture Society, answered these questions. He believes that the worry of "dripping Guanyin" is unnecessary, and there are no 52 kinds of cancer-promoting plants. Although toxic, it can be raised safely. In fact, many flowers in residents' homes are poisonous. Bamboo is a natural scavenger, which can remove harmful substances from the air, but it is also a poisonous flower. Green radish is evergreen all the year round and can absorb toxic gases, but the juice of green radish is toxic, which will be red and itchy when it comes into contact with the skin, and it will also cause sore throat if eaten by mistake; Evergreen belongs to Liliaceae, and the poisonous part is rhizome. Eating too much rhizome by mistake can cause nausea, abdominal pain, chills in limbs and even coma. Zebra is an evergreen plant, and the juice of its leaves can make people speechless.
Guo Xichang, a professor of forestry at Shenyang Agricultural University, believes that Euphorbiaceae and Daphne are also toxic, such as Kirin Crown, one of 52 cancer-promoting plants, which should not be planted at home. However, there is absolutely no need to smash poisonous flowers that can purify the air at home, such as dripping Guanyin and green radish.
Experts believe that the attitude towards poisonous plants should be: keep a proper distance and don't play around at will; You can't put branches and leaves in your mouth.
Experts also concluded that 10 bedroom should avoid placing all kinds of flowers: for example, the fragrance of orchids can cause insomnia; Mimosa may cause hair loss; Bauhinia pollen can cause asthma and aggravate cough; Cordate telosma can cause dizziness; Lily fragrance can cause insomnia; The fragrance of Chinese rose is depressing; The milky liquid secreted by oleander may be toxic; The fragrance of pine and cypress makes people lose appetite; Hydrangea is easy to cause allergies; Tulip flowers can cause hair loss.
The two professors also put forward some suggestions on what flowers to keep indoors in winter: the more flowers to keep indoors, the better. The Home Ownership Scheme with an area of 65,438+05 square meters only needs two pots of medium and large plants, while three or four pots of small plants can be placed.
