Plants that can absorb toxic chemicals, such as aloe, chlorophytum, Eupatorium odoratum, Eupatorium odoratum, Dendrocalamus japonicus, etc., are natural scavengers and 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. It can absorb 90% formaldehyde contained in 1 m3 air. Ivy, cycad, chrysanthemum, kumquat, pomegranate, Scutellaria barbata, rose, camellia, Milan, daisy, Chimonanthus praecox, calendula, etc. It can effectively remove harmful substances such as sulfur dioxide, chlorine, ether, ethylene, carbon monoxide and nitrogen peroxide. Orchids, osmanthus, wintersweet, cauliflower taro, osmanthus, etc. They are natural dust collectors, and their cilia can intercept and absorb floating particles and smoke in the air. 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, which increases 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. Plant creeper, grape, morning glory, wisteria, rose and other plants. Around the house, they can climb along the wall or along the frame 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. Aloe, chlorophytum, Eupatorium odoratum, Eupatorium odoratum and Dendrocalamus giganteum are natural scavengers. The research shows that aloe vera, Eupatorium odoratum and chlorophyllin have strong absorption ability to indoor harmful gas formaldehyde. Cycas evergreen, chrysanthemum, kumquat, pomegranate, mirabilis jalapa, Scutellaria barbata, rose, camellia, Milan, daisy, wintersweet and marigold can absorb harmful gases emitted by household appliances and plastic products. The volatile oils of rose, osmanthus fragrans, violet, jasmine, lemon, rose, carnation, lily of the valley and Lagerstroemia indica have obvious bactericidal effect. Crape myrtle, jasmine, lemon and other plants can kill protobacteria, such as diphtheria and dysentery bacteria, within 5 minutes. The fragrance of jasmine, rose, carnation, lily of the valley, violet, rose, osmanthus and other plants has obvious inhibitory effect on the growth and reproduction of mycobacterium tuberculosis, pneumococcus and staphylococcus. Hupilan, Huweilan, tequila, palm, dwarf kale, striped kale, Sedum, and cultivated pineapple can purify the air at night. If you put two pots of this plant, such as pineapple, in a room of 10 square meter, you can absorb all the carbon dioxide discharged by a person at night. Cactus, lotus, fairy finger, ruler and epiphyllum can increase negative ions. Turn on the TV or computer indoors, and the negative oxygen ions will decrease rapidly. The stomata on the fleshy stems of these plants are closed during the day and opened at night, which absorbs carbon dioxide and releases oxygen at the same time, increasing the concentration of negative ions in indoor air. Orchids, osmanthus fragrans, wintersweet, cauliflower taro and osmanthus fragrans can absorb suspended particles and smoke in the air. Lilac, jasmine, rose, violet, chrysanthemum, mint, these plants can relax people and help them sleep. In addition, plants that are too bright and harsh, have peculiar smell or are too fragrant should not be placed indoors. Such as: oleander, oleander and Datura flower. These flowers and plants are poisonous and harmful to human health. The fragrance of cordate telosma has a strong stimulating effect on people's sense of smell, and it will also discharge a lot of waste gas at night, which is not good for people. Evergreen stems and leaves contain dumb enzymes and calcium oxalate, which will cause strange itching when touching the skin, and poisoning when eaten by mistake. Other plants, such as tulips, contain poisonous alkali; Mimosa, frequent contact will cause hair loss; Narcissus, contact with leaves and flower juice, can cause skin redness and swelling. The number of flowers and plants placed in the general hall should be controlled within 3 pots; In terms of varieties, it is best to choose some plants that do not require high light, such as evergreen, cycad in Brazil, orchid in China, etc. It is best not to put flowers and plants in the bedroom. If you must put it, you can choose some small and delicate succulents such as cactus and cactus as decoration. Aloe, chlorophytum and Eupatorium adenophorum can remove formaldehyde. 15 square meter living room, planting two pots of Sansevieria or Chlorophytum can keep the air fresh and free of formaldehyde. Huwei orchid can also release a lot of oxygen during the day. Chlorophytum can also release fungicides to kill germs. If there are enough chlorophytum indoors, 80% of harmful substances will be killed within 24 hours. Chlorophytum can also absorb carbon dioxide effectively. Zi Yuan, Astragalus membranaceus, tobacco and Celosia cristata, these plants can absorb a lot of radionuclides such as uranium. Ivy, rose, rose, aloe and evergreen can effectively remove trichloroethylene, hydrogen sulfide, benzene, phenol, hydrogen fluoride and ether indoors. Eucalyptus, asparagus, spurge and cactus can kill germs, and asparagus can also remove heavy metal particles. Ivy, fig, Penglai banana and aloe can not only deal with harmful substances such as bacteria brought back from outdoors, but also absorb dust that is difficult for even a vacuum cleaner to absorb. Phyllostachys pubescens, Eupatorium odoratum and Eupatorium odoratum can absorb more than 80% of indoor harmful gases. Citrus, rosemary and chlorophytum can greatly reduce bacteria and microorganisms in indoor air. Roses can absorb more harmful gases, such as hydrogen sulfide, benzene, phenol, hydrogen chloride, ether and so on. Wisteria has strong resistance to sulfur dioxide, chlorine and hydrogen fluoride, and also has certain resistance to chromium. 1. Desert Oasis-Cactus If you put one or two pots of cactus next to the computer, it can help the human body absorb the radiation released by the computer as little as possible. Because cactus grows in a place with strong sunlight, it has a particularly strong ability to absorb radiation. Reason: 1. Cactus (balls) can resist radiation. Cactus and succulents are called "lazy plants". This kind of plant cultivation does not need much care and nursing, and hydroponic cactus is easier to maintain. Because cactus (ball) grows in strong sunlight, it is particularly resistant to ultraviolet rays. Hydroponic cactus is clean and environmentally friendly, and has no peculiar smell. If you put a pot or two of hydroponic cactus (balls) next to the computer, it can help the human body absorb the radiation released by the computer as little as possible. Because cactus (ball) grows in a place with strong sunlight, it has a particularly strong ability to absorb radiation. 2. Cactus cactus, known as the "oxygen bar" at night, breathes mostly when it is cool and humid at night. When breathing, inhale carbon dioxide and release oxygen. So putting a monster like Jin Hu in the room is tantamount to adding an air freshener, which can purify the indoor air. Therefore, it is also an ideal flower for indoor night decoration. 3, the master of dust adsorption, don't underestimate the cactus, people are still masters of dust adsorption! Placing a cactus indoors, especially hydroponic cactus (because hydroponic cactus is cleaner and more environmentally friendly), can purify the environment. Second, the "home-grown chlorophytum, dirty ghosts are scared." Chlorophytum is not only blue in appearance, but also bright green in all seasons, and it has a strong ability to absorb pollution. "The family grows chlorophytum, and the dirty ghost is shocked." People in southern Fujian, Taiwan Province Province and other places praise Chlorophytum in this way. Chlorophytum is the best plant to purify indoor air, which has been recognized by scientists. American environmental expert Bill? Warwell has done experiments. He put the chlorophytum in a special plexiglass container to give it a good light, then filled the polluted room with air, and measured the air composition absorbed by the chlorophytum after a period of time. It is found that there is little harmful gas left in the container, and its efficiency almost exceeds that of the air filter. Experiments show that chlorophytum can absorb and purify all harmful gases in the experimental container within 24 hours. As long as a pot of chlorophytum is put in the bedroom, harmful gases such as carbon monoxide and nitrogen peroxide emitted by indoor 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 and absorbed as nutrients. In its own metabolism, chlorophytum can also convert carcinogenic formaldehyde in the air into sugars, amino acids and other substances. Moreover, it can decompose benzene discharged from photocopiers and printers, and can also "swallow" nicotine and so on. Therefore, in a room of about 10 square meter, as long as there is a pot of chlorophytum, it is equivalent to installing an air purifier, which is enough to offset the negative effects brought by harmful gases. Scientists also put pots of chlorophytum in a closed environment like a space shuttle capsule. After 12 hours, the harmful gases such as carbon monoxide, nitrous oxide and formaldehyde in the cabin decreased by 85%. Researchers at Xi 'an Botanical Garden said that in recent years, more and more people chose chlorophytum as a family potted plant, and its pollution absorption ability was recognized by most people. Thirdly, aloe, which evolved from Arabic allcoh, is a folk herb. Aloe vera is not uncommon. Many beauty products contain aloe vera. 4. Canna Canna has a strong ability to absorb sulfur dioxide. Perennial herbs of Cannaceae. Easy to cultivate, like sunshine and warm climate, not cold-resistant. The requirements for soil are not strict, and fertile, deep and well-drained sandy loam is the best. Fear of waterlogging, soil water is easy to rot roots. Short-flowered and large-flowered varieties can be selected when potted. Canna tubers should be buried in pots with a diameter of about 40 cm in late April. Before planting, sufficient organic fertilizer combined with nitrogen and phosphorus should be applied to the bottom of the pot as base fertilizer. During the growth and flowering period, compound liquid fertilizer (or fat water made of chicken manure or sesame sauce residue) should be applied many times. Don't water it too often after planting, and put it in a sunny and ventilated place indoors. If fertilizer is insufficient or phosphorus and potassium fertilizer are not applied, the plants will only grow stems and leaves, and rarely or not bloom. After the flowers wither, Hualien should cut them off in time and apply liquid fertilizer. Evergreen can effectively remove the pollution of triethylene. Perennial evergreen herbs of Liliaceae. Rhizomes are thick and short, with fibrous roots, basal leaves, banded or oblanceolate, and terminal spikes. There are many cultivated varieties, such as Phnom Penh, Silver Border and Spotted Evergreen. I like semi-cool environment, and put it in a cool place in summer to avoid strong light. I can change the pot once a year from March to April. When changing pots, I will remove the aged roots and persistent dead leaves and plant them in acidic cultivation soil with base fertilizer. Leave it in the shade for a few days after serving. Don't water the basin when watering, it would be dry rather than too wet. In addition to keeping the soil moist in summer (when the climate is hot, water should be sprayed around the flowerpot in the morning and evening), and watering should not be too frequent in spring and autumn. Dilute liquid fertilizer can be applied two or three times during the growth period. Potted soil can be cultivated in general garden soil, but sandy loam with rich humus and good water permeability is the best. In addition, tiger-eye evergreen, Guangdong evergreen and mosaic evergreen can all be used as indoor potted plants. Dendrocalamus giganteus has a strong ability to absorb carbon dioxide at night. Also known as Penglai banana, Araceae perennial evergreen vine. There are also spotted leaves, bamboos and so on. Its stem is as thick as bamboo, and there are a lot of fleshy air roots on it. Leaves alternate, the leaves are nearly round and huge, and the young leaves are heart-shaped without perforation. When it grows up, its big leaves are scattered with many rectangular holes and deep cracks in the shape of tortoise shells. Native to South America, I like warm and humid environment, prefer semi-cloudy, avoid direct sunlight, and prefer fertile sandy loam rich in humus. Potted soil can be mixed with humus soil (peat soil) 2 parts+garden soil 1 part+river sand 1 part+a small amount of base fertilizer. The suitable growth temperature is 20 ~ 25℃, and the overwintering temperature is more than 8℃. Thin liquid fertilizer (such as cake fertilizer and water) can be applied once a month during the growing period, and it is usually better to be wet than dry. When the air is dry, you can spray water on the leaves and the ground. When a plant grows up, it needs to be supported or climbed along the object. Cutting is the main breeding method. In April and May, stem segments with two or three nodes can be cut. After removing aerial roots, it can be vertically inserted into plain sand pots, with one section exposed outside the sand, and one plant in each pot can be placed in a warm and semi-cool place for moisturizing. It can take root and sprout in one month. 6. In addition, plants that can absorb carbon dioxide at night include Crataegus pinnatifida, Crataegus pinnatifida, cactus cactus, purple pineapple and torch pineapple of pineapple family, and bottle orchid of agave family. Plants that can purify the air are pomegranate, carnation, rose, rose, daisy, flying grass, sedge and so on. Reasonable collocation of indoor greening plants can be more conducive to our health, such as excessive formaldehyde, electromagnetic radiation, kitchen fumes, cigarette dust, street noise ... With a large number of luxurious decoration of modern offices and bedrooms, indoor pollution has greatly increased, making people smell "very dirty". Yesterday, a famous horticulture and forestry expert and senior engineer, known as "Dr. Hua" in Shencheng, disclosed 60 kinds of domestic flowers that can reduce pollution and purify the air for the first time in China. The reporter found that these "flowers and plants special attack teams" to stop environmental pollution are ordinary plants that citizens can usually buy, afford and grow easily. At the same time, "Home Flowers for Purifying the Air" edited by him will appear at the "2005 Shanghai Book Fair" which will open tomorrow. Domestic chlorophytum and aloe can block formaldehyde, and a small pot of chlorophytum can deal with the number one "killer" in newly renovated houses-formaldehyde. If you put one or two pots of chlorophytum indoors, toxic and harmful gases such as formaldehyde can be greatly reduced. Among many plants that absorb toxic substances, chlorophytum plays a primary role. Generally speaking, a pot of chlorophytum can absorb 96% of carbon monoxide and 86% of formaldehyde in a cubic meter of air, and can also decompose benzene emitted by the copier, which is irreplaceable by other plants. In particular, Chlorophytum can carry out photosynthesis and absorb toxic gases in weak light, especially Chlorophytum likes shade and is more suitable for indoor display. In contrast, aloe likes sunshine, and it is more suitable to be placed in a bright place to exert its greatest effect. According to the test, a pot of aloe can absorb about 90% of formaldehyde in one cubic meter of air. It is understood that plants that can absorb formaldehyde include orchids, Eupatorium odoratum, Eupatorium odoratum, Cymbidium hybridum and Dendrocalamus giganteum. Air pollution can be monitored when flowers and plants are sick. In fact, many flowers and plants can also monitor the air. Once the flowers and plants at home are found to be' sick', the culprit may be indoor air. Inadvertently, if you find that flowers and plants are' sick', you may need to be alert to whether your room has environmental pollution and whether you need to do air testing. "There are many flowers and plants that can monitor the air. For example: corn poppy, canna, day lily, rhododendron, peony, morning glory, begonia and plum blossom. For example, corn poppy is extremely sensitive to the reaction of the toxic gas hydrogen sulfide. If attacked by this toxic gas, its leaves will be burnt or spotted, which can be used as an ideal monitoring plant. When canna leaves turn green and white and flowers and fruits fall off, special attention should be paid to chlorine pollution; When there is fluorine pollution in the air, the tip of day lily leaves will turn brown, which can be used to monitor environmental fluorine pollution. Peach blossom is also a good indicator plant for monitoring sulfide and chlorine emissions; Plum blossoms also have the function of monitoring formaldehyde. Plant a cypress tree in the house along the street to reduce noise. Not a good place to buy a house. I have to buy a commercial house along the street or beside the elevated road. I always feel noise, car horns and cars coming and going on overhead 24 hours a day ... even if I spend a lot of money, I can't keep the window open all day ... In fact, many plants have the function of absorbing noise. For example, cypress and conifer are very good "noise absorbers". Ivy and Cycas can absorb benzene if I put it in. According to calculation, these two plants can remove 80% benzene released by cigarettes and man-made fibers. Put a cactus next to the computer to prevent radiation and isolate the electromagnetic radiation of the computer. In addition to computer screen protectors and radiation protection suits, a small cactus can also reduce the possible harm caused by electromagnetic radiation. The stomata at the fleshy base of cactus will be closed during the day and opened at night, so it will absorb carbon dioxide and release oxygen at night, so it can increase fresh air and negative ions. In addition, it also has a good inhibitory effect on bacteria in the air. " However, to really play the greatest role of flowers in preventing environmental pollution, it also involves the location of flowers. If the position is correct, the effect of cactus can be revealed. Therefore, it is necessary to decide what kind of plants to plant and where to put them according to the habits of each plant and its role in purifying the air. "If you are near the TV, you can put a pot of golden lake, which is the strongest ability to reduce electromagnetic radiation in cactus. However, prickly plants like cactus should not be placed in children's rooms to avoid accidental injury.
