If you put a cactus or two next to your 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 sunshine, it has a particularly strong ability to absorb radiation.

In the field of flower gardening, it is customary to call the spherical variety of cactus plants cactus; The cactus is a kind of stem, leaves and flowers with high ornamental value. The traditional cactus is planted in the desert, and the hydroponic cactus cultivated by plant aquatic mutagenesis technology can not only see its white and tender roots, but also see the cute little fish swimming among the roots, which is really pleasing to the eye. It is an artistic masterpiece of hydroponic flowers.

Application value of hydroponic cactus

cactus

Cactus and succulents have their own names-"lazy plants". This kind of plant cultivation does not need much care and care, and hydroponic cactus is easier to maintain. Because cactus grows in a place with strong sunshine, it is particularly resistant to ultraviolet radiation. Hydroponic cactus is clean and environmentally friendly, and has no peculiar smell. If you put a pot or two of hydroponic cactus next to your 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 sunshine, it has a particularly strong ability to absorb radiation.

Known as the night "oxygen bar" cactus.

Most cactus breathing is carried out at night when it is cool and humid. When breathing, inhale carbon dioxide and release oxygen. Therefore, putting a giant like Jinhu 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 decoration at night. 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.

Xinhua Online Haihai, March 23 (Zhangyuan) The prominent anti-cancer, anti-aging and anti-radiation functions of cruciferous plants have always been concerned by the scientific community. Shanghai researchers screened a natural radioprotective agent from cruciferous plants and vegetables.

This protective agent, called SP88, is a small molecule aromatic compound, which can be dissolved in water and ethanol. Researchers from Shanghai Institute of Physiology and Ecology, Chinese Academy of Sciences have proved through experiments that its anti-radiation protection is achieved by eliminating the anions produced by radiation on DNA. When the concentration of SP88 reaches 0.78g per hour, the DNA damage caused by ionizing radiation can be completely prevented. SP88 also has the function of scavenging superoxide anion radical and hydroxyl radical. It is confirmed that SP88 can completely eliminate hydroxyl radicals produced in the experimental system.

The experiment of radiation protection of SP88 in mice found that after taking SP88 after ionizing radiation, not only the mortality rate was reduced, but also the decrease of white blood cells and platelets caused by radiation and the micronucleus rate of polychromatic erythrocytes in bone marrow caused by radiation were alleviated, which also proved that SP88 had a very obvious radiation protection effect on mice. The experiment of sex-linked recessive lethal mutation in Drosophila showed that SP88 could reduce the mutation rate of Drosophila caused by ionizing radiation to the normal range. In the anti-aging experiment of Drosophila melanogaster, SP88 can obviously prolong the maximum life span and average life span of experimental Drosophila melanogaster.

According to the researchers, experiments have proved that SP88 has a strong absorption effect in the ultraviolet section that is harmful to human skin, and it has no irritation to the skin. When used in cosmetics production, it can reduce the damage of ultraviolet rays in sunlight to human skin and effectively prevent skin aging and wrinkles.

Plants that can absorb toxic chemicals

Aloe, chlorophytum, Eupatorium odoratum, Eupatorium odoratum and Phyllostachys giganteum are natural scavengers, which can remove harmful substances in the air. Studies have shown 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, and it can absorb 90% of formaldehyde contained in 1 m3 air.

Ivy, Cycas, Chrysanthemum, Kumquat, Pomegranate, Scutellaria barbata, Chinese rose, Camellia, Milan, Daisy, Chimonanthus praecox, Marigold, etc. can efficiently remove harmful substances such as sulfur dioxide, chlorine, ether, ethylene, carbon monoxide and nitrogen peroxide.

Orchids, osmanthus fragrans, Chimonanthus praecox, cauliflower taro, osmanthus fragrans, etc. are natural dust collectors, and their cilia can intercept and absorb floating particles and smoke in the air.

Plants that can kill germs

Volatile oils produced by fragrant flowers such as rose, osmanthus fragrans, violet, jasmine, lemon, rose, carnation, lily of the valley, crape myrtle, etc. have significant bactericidal effect.

Plants such as crape myrtle, jasmine and lemon can kill protobacteria such as diphtheria and dysentery bacteria in 5 minutes. The fragrance of 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.

Cactus and other succulent plants native to tropical arid areas, the stomata on their succulent stems are closed during the day and opened at night, and oxygen is produced while absorbing carbon dioxide, which increases the concentration of negative ions in indoor air.

Hupilan, Huweilan, Tequila, Palmetto, Kale, Sedum, Rooting, Pineapple and other plants can also purify the air at night.

Plants such as Parthenocissus tricuspidata, grape, morning glory, wisteria, rose, etc. are planted around the house, so that they can climb along the wall or along the shelf to form a green arbor, which can effectively reduce the sunlight radiation and greatly reduce the indoor temperature.

Lilac, jasmine, rose, violet, mint and other plants can relax people, make them happy, help them sleep and improve their work efficiency.

Aloe vera, chlorophytum, Eupatorium odoratum, Eupatorium odoratum and Phyllostachys giganteum are natural scavengers. Studies have shown that aloe vera, Eupatorium odoratum and Chlorophytum chlorophyllum have strong ability to absorb formaldehyde, a harmful indoor gas.

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.

Volatile oils from rose, osmanthus fragrans, violet, jasmine, lemon, rose, carnation, lily of the valley and crape myrtle have significant bactericidal effect. Plants such as crape myrtle, jasmine and lemon 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, Palmetto, Dwarf Kale, Striped Kale, Sedum crassifolia and cultivated pineapple can purify the air at night. 10 square meter indoor, if there are two pots of such plants, such as pineapple, you can absorb all the carbon dioxide discharged by a person at night.

Cactus, lotus flower, fairy finger, ruler and epiphyllum can increase negative ions. When a TV or computer is turned on indoors, 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.

Orchid, osmanthus fragrans, Chimonanthus praecox, cauliflower taro and osmanthus fragrans can absorb floating 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 have too strong fragrance 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 enzyme and calcium oxalate, which will cause strange itching when touching the skin, eating it by mistake and causing poisoning. Other plants, such as tulips, contain toxic alkali; Mimosa, frequent contact will cause hair loss; Narcissus, contact with leaves and flower juice, can cause skin redness and swelling.

Generally, the number of flowers and plants placed in the 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, Cycas brasiliensis and China orchids; It is best not to put flowers and plants in the bedroom. If you must put them, you can choose some small and exquisite succulent plants such as cactus and cactus as decorations.

Aloe vera, chlorophytum and Eupatorium adenophorum can remove formaldehyde. 15 square meters of living room, planting two pots of tiger's tail orchid or chlorophytum can keep the air fresh and free from formaldehyde. Huwei orchid can also release a lot of oxygen during the day. Chlorophytum can also emit fungicides and kill germs. If there are enough chlorophytum in the room, 80% of harmful substances will be killed within 24 hours. Chlorophytum can also effectively absorb carbon dioxide.

Zi Yuan, Astragalus, tobacco and Celosia cristata, these plants can absorb a lot of radioactive nuclides such as uranium.

Ivy, rose, rose, aloe and evergreen can effectively remove trichloroethylene, sulfur hydrogen, benzene, phenol, hydrogen fluoride and ether in the room.

Eucalyptus, asparagus, spurge and cactus can kill germs, and asparagus can also remove heavy metal particles.

Ivy, fig, Penglai banana and aloe vera can not only deal with bacteria and other harmful substances brought back from outdoor, but also absorb dust that is difficult for even vacuum cleaners to absorb.

Phyllostachys pubescens, Eupatorium odoratum and Eupatorium odoratum can absorb more than 80% harmful gases indoors.

Citrus, rosemary and chlorophytum can greatly reduce bacteria and microorganisms in indoor air.

Rose can absorb more harmful gases such as hydrogen sulfide, benzene, phenol, hydrogen chloride and ether.

Wisteria has strong resistance to sulfur dioxide, chlorine and hydrogen fluoride, and also has certain resistance to chromium.

First, the desert oasis-cactus

If you put a cactus or two next to your 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 sunshine, it has a particularly strong ability to absorb radiation.

Reason:

1, cactus (ball) can resist radiation.

Cactus and succulents are called "lazy plants". This kind of plant cultivation does not need much care and care, and hydroponic cactus is easier to maintain. Because cactus (ball) grows in a place with strong sunshine, it is particularly resistant to ultraviolet radiation. Hydroponic cactus is clean and environmentally friendly, and has no odor. If you put a pot or two of hydroponic cactus (balls) next to your 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 sunshine, it has a particularly strong ability to absorb radiation.

2, known as the night "oxygen bar" cactus.

Most cactus breathing is carried out at night when it is cool and humid. When breathing, inhale carbon dioxide and release oxygen. Therefore, putting a giant like Jinhu 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 decoration at night.

3, 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 family grows chlorophytum, and the dirty ghost is frightened."

Chlorophytum is not only blue in shape and bright green in all seasons, but also has a strong ability to absorb pollution. "The family grows chlorophytum, and the dirty ghost is frightened." People in southern Fujian, Taiwan Province and other places praised Chlorophytum in this way.

Chlorophytum is the best plant to purify indoor air, which has been approved by scientists. American environmental expert Bill? Warwell once conducted experiments. He put the chlorophytum in a special plexiglass container, gave it a good light, then filled the air in the polluted room, and measured the air composition absorbed by the chlorophytum after a while. It was found that there were few harmful gases left in the container, and its efficiency almost exceeded that of the air filter. Experiments show that chlorophytum can absorb and purify all the 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 from indoor appliances, stoves, plastic products and paints can be absorbed and transported to the roots in one day, and then decomposed into harmless substances by microorganisms in the soil, which are absorbed as nutrients. In its own metabolism, chlorophytum can also convert carcinogenic formaldehyde in the air into substances such as sugar and amino acids. And it can decompose benzene emitted by photocopiers and printers, and it 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 several pots of chlorophytum in a closed environment like the space shuttle capsule. After 12 hours, harmful gases such as carbon monoxide, nitrous oxide and formaldehyde in the capsule were reduced by 85%. Researchers at Xi 'an Botanical Garden said that in recent years, more and more people have chosen chlorophytum as a family potted plant, and its pollution absorption ability has been recognized by most people.

Third, aloe vera

Aloe vera, evolved from Arabic allcoh, is a folk herb. Aloe vera is not unusual. Many beauty products contain aloe vera.

Fourth, canna

Canna has a strong ability to absorb sulfur dioxide.

Perennial perennial herbs of Cannaceae. Easy to cultivate, like sunny and warm climate, not cold-resistant. The requirements for soil are not strict, and the fertile, deep and well-drained sandy loam is the best. Fear of waterlogging, soil water is easy to rot roots. Short and large-flowered varieties can be selected when potted. Canna tubers should be buried in a pot 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, it is necessary to apply compound liquid fertilizer several times (fat water made from chicken manure or sesame sauce residue can also be applied). Don't water it too often after planting, and put it indoors in a sunny and ventilated place. If fertilizer is insufficient or phosphorus and potassium fertilizer are not applied, the plant will grow only stems and leaves, and there will be few or no flowers. After the flowers wither, Hualien should be cut off in time and liquid fertilizer should be applied.

Evergreen can effectively remove the pollution of triethylene.

Perennial evergreen herb of Liliaceae. The rhizome is thick and short, with fibrous roots at the nodes, basal leaves, banded or oblanceolate, and terminal spikes. There are many cultivated varieties, such as Phnom Penh, Silver Edge and Spotted Evergreen. I like semi-shady environment, and put it in a shady place in summer to avoid strong light. I can change the pot once every March to April. When changing the pot, I will remove the aged rhizomes and persistent dead leaves and plant them in acidic cultivation soil with base fertilizer. Put it in the shade for a few days after serving. Watering should be done without watering the basin soil, rather dry 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), watering in spring and autumn should not be too frequent. Thin liquid fertilizer can be applied twice or three times in the growth period. Pot 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.

V. Phyllostachys pubescens

Bambusa bambusa has a strong ability to absorb carbon dioxide at night.

Also known as Penglai banana, Araceae perennial evergreen vine. There are also mottled leaves, bamboos with oblique leaves and so on. Its stems are stout and bamboo-like, and there are a lot of fleshy air roots on the stems. The leaves are alternate, the leaves are nearly round and huge, and the young leaves are heart-shaped without perforation. When it grows up, many oblong holes and deep cracks are scattered in the shape of tortoise shells on its large leaves. Native to South America, I like warm and humid environment, prefer semi-cloudy, avoid direct sunlight, and prefer fertile sandy loam rich in humus. Pot soil can be mixed with 2 parts of humus soil (peat soil)+garden soil 1 part+river sand 1 part+a small amount of base fertilizer. The suitable growth temperature is 20℃ to 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 growth period, and it is better to be wet than dry at ordinary times. When the air is dry, water can be sprayed on the leaves and the ground. When the plant grows up, it needs to be supported or climbed along the object. Propagation is mainly based on cutting. In April and May, stem segments with two or three nodes can be cut. After removing aerial roots, they can be vertically inserted into plain sand pots, with one node exposed outside the sand, and one plant in each pot can be placed in a warm and semi-shady place for moisture preservation. Rooting and budding can be carried out in one month.

6. In addition, plants that can absorb carbon dioxide at night include Crab Claw Orchid, Crab Peony, Immortal Column of Cactaceae, Purple Pineapple and Torch Pineapple of Bromeliaceae, and Bottle Orchid of Agavaceae. Plants that can purify the air include pomegranate, carnation, rose, rose, daisy, Eupatorium odoratum, sedge and so on. Indoor greening plants should be reasonably matched in order to be more conducive to our health.

Excessive formaldehyde, electromagnetic radiation, kitchen fume, cigarette dust, street noise ... With a large number of luxurious decoration in modern offices and bedrooms, indoor pollution has greatly increased, which makes people smell "dirty" and change color. Yesterday, senior engineer Wu Zhixing, a well-known horticulture and forestry expert known as Dr. Hua in Shencheng, disclosed 60 kinds of domestic flowers and plants 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, the "Domestic Flowers and Plants for Purifying the Air" edited by him will appear at the "2005 Shanghai Book Fair" which will open tomorrow.

Domestic chlorophytum and aloe prevent formaldehyde

A small pot of chlorophytum can deal with the number one "killer" in the newly renovated room-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 the first 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 photocopiers, which is irreplaceable by other plants. In particular, chlorophytum can carry out photosynthesis and absorb toxic gases in weak light, especially chlorophytum likes shade, which is more suitable for indoor placement. In contrast, Aloe Vera likes the sun, 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% 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 Phyllostachys giganteum.

Flowers and plants "sick" can monitor air pollution.

"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 the indoor air. Inadvertently, if you find that flowers and plants are' sick', you may also need to be wary of whether there is environmental pollution in your room and whether you need to do an air test. "

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 toxic gas hydrogen sulfide. If it is attacked by such 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, we should pay special attention to chlorine pollution; When there is fluorine pollution in the air, the tip of HEMEROCALLIS HEMEROCALLIS leaves will turn brownish red, 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.

Put a cypress tree in the room along the street to reduce noise.

The location of the house is not good, so I have to buy a commercial house along the street or adjacent to the elevated building. Every day, I always feel noise, car horns and cars coming and going on the elevated building ... 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". If I put them in the window or balcony of the room,

Ivy and Cycas can absorb benzene. It has been calculated that these two plants can remove 80% benzene released from cigarettes and man-made fibers.

Cactus placed next to computer for radiation protection

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 on 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 has the function of increasing fresh air and negative ions. In addition, it also has a good inhibitory effect on bacteria in the air.

"But to really play the biggest role of flowers and plants in preventing environmental pollution, it also involves the location of flowers and plants. If the location is correct, the effectiveness of cactus can be revealed. Therefore, it is necessary to decide what kind of plants to plant and where to place them according to the habits of each plant and the role of purifying the air. " If you are near the TV, you can put a pot of Jinhu, which has the strongest ability to reduce electromagnetic radiation in cactus. However, plants with thorns like cacti should not be placed in children's rooms to avoid accidental injuries.
