What kind of flowers and plants are the best at home? Tell me why.

We all know that indoor air quality is very important to human health, so some air purifiers, adsorbents and humidifiers have appeared to adjust indoor air humidity. In fact, green plants have similar functions to these advanced devices. They also have beautiful shapes, fresh colors and vitality. Then you might as well keep a few pots of plants in your room as a natural air purifier. What are the benefits of plants in the living room? If green occupies 25% of the visual field, it can eliminate the physiological fatigue of the eyes. Therefore, putting green plants indoors not only plays the role of room decoration, but also creates a good indoor environment, which is pleasing to the eye and meets people's psychological requirements, and can also make people relax in intense work. Volatile substances released by aromatic plants can regulate people's mood well. Some flowers can change people's listless state and cheer them up, while others have the effect of calming and helping sleep. Release oxygen Most plants carry out photosynthesis, absorbing carbon dioxide to release oxygen during the day and breathing oxygen to release carbon dioxide at night. However, some plants such as cactus are just the opposite. In order to avoid water loss during the day, the stomata are closed, and at night the stomata are opened to release oxygen produced by photosynthesis. Since plants have this "complementary" function, raising two kinds of plants in the same room can balance the contents of indoor oxygen and carbon dioxide and keep the indoor air fresh. Humidity-regulating water is absorbed by indoor plants and then emitted into the air through transpiration of leaves, which can play a role in regulating air humidity. This function is particularly important in the dry north and closed rooms with air conditioning. Drug abuse and sterilization With the improvement of living standards, room decoration is essential, and those decoration materials contain toxic substances more or less. Some flowers have strong anti-poison ability and can absorb some toxic gases in the air, such as sulfur dioxide, nitrogen oxides, formaldehyde, hydrogen chloride and so on. Some foliage plants also absorb radioactive substances. The volatile oil from some flowers has obvious bactericidal effect and can make indoor air clean and hygienic. The functions of various flowers, such as camellia, cyclamen, violet, tuberose, impatiens, Dianthus, gladiolus and so on. The highly toxic sulfur dioxide can be converted into non-toxic or low-toxic sulfate through leaves. Narcissus, mirabilis jalapa, chrysanthemum and protein can transform nitrogen oxides into plant cells. Chlorophytum and aloe can absorb a lot of indoor formaldehyde and other pollutants, and eliminate and prevent indoor air pollution. Especially if you put a pot in the living room, its leaves will "eat" harmful gases such as carbon monoxide in the indoor air within 24 hours, and its effect even exceeds that of the air filter. Pomegranate and chrysanthemum have the ability to absorb sulfur, hydrogen fluoride and mercury. Germicides secreted by flowers such as jasmine can kill some bacteria in the air and inhibit the growth of tuberculosis, dysentery and typhoid fever. The fragrance of jasmine can relieve dizziness and cold and stuffy nose. People with headaches, dizziness, colds and blurred vision often smell chrysanthemums. Cactus plants release carbon dioxide during the day and absorb carbon dioxide at night to release oxygen, so it is also quite good to put a cactus in the bedroom. Besides cacti, orchids of Orchidaceae, Clivia of Amaryllidaceae and Narcissus also have this peculiar function. Nowadays, people pay more and more attention to the quality of indoor environment. Adding green plants to indoor decoration can not only beautify the room, but also improve the indoor air quality, which can kill two birds with one stone. Special note ● Although flowers have many benefits, you can't regard the living room as a "greenhouse", because indoor ventilation is limited, there are too many flowers and trees, which will compete with people for land, and most of the living rooms are closed at night. In addition, the carbon dioxide exhaled by pets in soil, human body and flower pots will increase the concentration of carbon dioxide, resulting in human hypoxia, which is not good for health. ● The purification function of plants is limited. So always open the window to let the air convection. ● Pine and cypress bonsai should not be placed indoors, and its rich pine fragrance will affect people's appetite. ● Cloves, cordate telosma, etc. Breathing a lot at night, the harmful gases discharged make people with high blood pressure and heart disease feel stuffy, and normal people will also have symptoms such as dizziness and insomnia. ● Western hydrangeas and colored plums can cause allergic reactions in some people. Tulips and mimosa contain toxic alkali, which can cause hair loss. Reference: /xinwen/xw The following three plants are suitable for indoor display. You can choose from these plants according to your own preference: 1 Plants that can absorb toxic chemicals, such as aloe, chlorophytum, Eupatorium odoratum and Dendrocalamus japonicus, are natural scavengers, which can remove harmful substances in the 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. 2 Mosquito repellent plant mosquito net vanilla is such a plant. It is an aromatic geraniaceae plant, its genetic structure has been changed, and it has only been introduced from Australia in recent years. The plant is drought-tolerant, can grow and mature within half a year, can survive for 10- 15 years after proper maintenance, and the shape of branches and leaves can be changed at will, so it has high ornamental value. Mosquito net vanilla gives off a fresh and elegant lemon fragrance, which has a good mosquito repellent effect indoors, but it has no toxic side effects on human body. The higher the temperature, the more fragrance it emits, and the better the mosquito repellent effect. According to the test, a pot of mosquito net vanilla with a crown width of more than 30 cm can drive away mosquitoes in a room with an area of more than 10 square meter. In addition, a plant called pyrethrum contains pyrethrins, which can also effectively repel mosquitoes. The volatile oil produced by fragrant flowers that can kill germs, such as rose, osmanthus fragrans, violet, jasmine, lemon, rose, carnation, lily of the valley and crape myrtle, has obvious bactericidal 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 succulents native to 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. It should be noted that positive flowers, such as pomegranate, jasmine, Milan, rose, etc., can only be seen in turn indoors for a short time. Even neutral and negative plants need to be moved to appropriate locations outdoors regularly for rejuvenation. If it is a green plant that has just moved into a new house, priority should be given to plants with strong resistance, easy feeding and pollution absorption. I suggest you choose longevity flower first. Longevity flower, a plant belonging to the genus Kaleida of Crassulaceae, not only has the function of releasing oxygen during the day, but also has the function of absorbing carbon dioxide at night, which most flowers do not have. It can not only watch flowers for a long time, but also make the air fresh when placed indoors. In addition, the leaves of the longevity flower are dense and green, and most of them bloom near Christmas, clustered and colorful. It is a lovely indoor potted flower. The arrangement of windowsill, desk and desk is very suitable. Because the name is Longevity Flower, it's lucky to send a pot of Longevity Flower to relatives and friends on holidays, which is very long-lived and pleasing. Longevity flower is a perennial succulent herb. The stems are erect, and the plant height is 10 ~ 30 cm. Opposite leaves, rectangular spoon-shaped, dark green, compact plant type and dense flowers are ideal indoor potted flowers in autumn, winter and spring. Longevity flowers are scarlet, pink, orange, yellow, orange and white. The flowering period is very long, reaching 2 ~ 5 months; There are many colors, including pink, pure white, orange, crimson, brownish red, yellow, orange and red. It blooms in the morning and evening, in early September, in the winter and Spring Festival Evening, and can last until April to May of the following year. The price is also quite cheap. When it is expensive, it costs more than 10, and when it is cheap, it costs only 1 5 yuan. If you are interested, you can choose several colors to put together. Now it's time to start maintenance. Other flowers, such as tiger orchid, crab claw orchid, chlorophytum, etc., are not only easy to raise, but also experts in purifying the air. Taxodium ascendens is a long green woody plant with high indoor air purification index. Its unparalleled shade tolerance, long-term indoor can also grow normally, not afraid of drying, not afraid of humidity. It doesn't hurt to apply some basic fertilizer once in the basin, and it doesn't hurt to not apply it for 1~2 years. With a little pruning, it is a beautiful and exquisite tree bonsai. If you want to further create a beautiful and quiet atmosphere in the room, you can put some small and medium-sized plants with exquisite and elegant appearance, such as asparagus, chlorophytum, Hedyotis diffusa, ivy, radish, bamboo banana, taro, and non-prickly and fleshy plants, such as gem flowers, squirrel claws, aloe and so on. In addition, there are orchids, calla lilies and colored taro. Before and after the New Year's Day to the Spring Festival, you can appropriately raise some seasonal flowers such as Chimonanthus praecox, silver willow, Spring Festival, narcissus, big-flowered Tianzhu and other precious flowers. Of course, the maintenance of these flowers will be more difficult. However, although there are so many plants that can purify indoor air, almost all plants can't move indoors, and most plants absorb oxygen at night. Therefore, window ventilation is the best way to purify the air. Planting flowers and grass only regulates the visual environment and people's mood, and its effect on purifying the air is really negligible.
