What plants wilt when exposed to carbon dioxide?

It is theoretically impossible to exist. Plants are autotrophs, and their growth depends on photosynthesis, and the raw material of dark reaction of photosynthesis is carbon dioxide. In other words, plants can't grow without carbon dioxide. After a period of time, the organic matter in plants will be exhausted and will die. But I have some information that I don't know if it will help you. Some people think that planting flowers in the bedroom will make the air turbid at night and reduce the oxygen content, which will affect people's lives, so they advocate not planting flowers in the bedroom. In fact, this is only a general inference, ignoring the analysis of the amount of substance transformation in the process of plant life activities and the phenomenon that flowers release some substances beneficial to human health at night. It turns out that all plants, including flowers, have the breathing function of inhaling oxygen at night, but compared with people, they are very weak, because every time a flower inhales two oxygen atoms, it must combine with a carbon atom in its own body and release a carbon dioxide molecule; Because the wet weight of the whole potted flower generally does not exceed 500g, the dry matter is only tens of grams, and the carbon content is even limited. Even if it is oxidized overnight to synthesize carbon dioxide, it is at most equal to the carbon dioxide produced by burning dozens of grams of anthracite. Plants can never convert carbon atoms in their bodies into carbon dioxide overnight.

According to scientific experiments, a potted flower consumes only 0. 1g of carbon in the body at night due to respiration, so the total amount of carbon dioxide released by ten potted flowers is exactly equivalent to that produced by smoking a cigarette. It can be seen that poor ventilation and air turbidity in the bedroom cause people's physical and mental unhappiness, which has nothing to do with flower cultivation. In addition, some flowers, such as jasmine, rose, cordate telosma and so on. It can emit volatile essential oil and negative ions day and night, which has the function of refreshing the air, and often keeps the bedroom air clean. The fragrance contained in it is refreshing and can eliminate fatigue. Some floral scents can also treat chronic diseases such as mental depression and neurasthenia. The fragrance of cordate telosma has the function of repelling mosquitoes. Hydrangea, begonia, asparagus, etc. It can not only absorb harmful gases such as sulfur dioxide, nitrogen dioxide and chlorine at night, but also secrete bactericidal gases, reducing the occurrence of infectious diseases such as colds, typhoid fever and laryngitis, which is of great benefit to human health.

Of course, when growing flowers in the bedroom, we should keep the soil clean, fertilize deeply, don't apply immature organic fertilizer, and remove dead flowers and leaves in time. In this way, it is really good to raise flowers in the bedroom, so you don't have to worry. Besides bathing plants in fog, there is no need to move potted plants outdoors at night. Obviously, they can safely grow flowers in their bedroom.

Recently, NASA scientists found that many evergreen foliage plants and green flowering plants have the function of eliminating toxic chemicals in buildings. The study also found that plants not only rely on leaves to absorb substances, but also the roots of plants and bacteria in the soil contribute to the removal of harmful substances. Zhou, an engineer at the Indoor Environmental Monitoring Center of China Decoration Association, believes that the following two types of plants are most suitable for indoor use.

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.

Flowers should mainly beautify the environment. Good flowers can not only enjoy the sight, but also purify the air. In fact, different flowers should be placed in different places, and some flowers are still not suitable for entering the house, otherwise it will cause air pollution.

Aromatic function of common flowers

Roses are sweet: relax nerves, relieve physical and mental fatigue, and help to treat nervous system diseases.

Tulip: It can relieve eye fatigue and irritability.

Orchid fragrance: relieving lung heat, resolving phlegm and relieving cough is good for people with neurasthenia, but it should not be too strong, otherwise it will also cause dizziness.

White orchid fragrance: it can sterilize and purify the air.

Chrysanthemum flower fragrance: it can clear away heat and dispel wind, clear liver and improve eyesight, and can be used as an auxiliary treatment for headache.

Clove: It has obvious air purification ability and strong sterilization ability. Putting cloves indoors can prevent infectious diseases to a certain extent, but its fragrance is rich and it is not suitable to smell, otherwise it will make you dizzy.

Narcissus: It can make people feel quiet and warm.

Clever flower arrangement in the hall can prevent diseases ... >>& gt Three kinds of plants are suitable for indoor display.

Experts pointed out that indoor flowers should be planted with flowers that can absorb toxic gases, purify the air or sterilize, and some flowers themselves have the function of preventing and treating diseases. For example, chrysanthemum and wintersweet have the ability to absorb sulfur and hydrogen fluoride, and the volatile oil secreted by thyme and clove has bactericidal effect. Jasmine, Milan, osmanthus, crape myrtle, rose, rose, etc. It can emit volatile oil with bactericidal effect, while Ren Mei gum and honeysuckle have a strong absorption effect on fluorine, and so on.

Don't plant flowers in the ward and bedroom at night.

Many flowers have the function of purifying the air and promoting health, but if you keep some flowers at home, they will become the source of disease or the "killer" who leads to the recurrence and aggravation of old diseases. Therefore, experts suggest that you must know the nature of flowers before raising them. In case flowers are kept at home, your body will have problems.

Patients should not keep potted flowers indoors-because the soil in the flowerpot will produce fungal spores. When they spread into the air, they can easily invade people's skin, respiratory tract, external auditory canal, meninges and brain, causing infection, which is very harmful to patients with existing diseases.

Flowers should not be placed in the bedroom at night-because most flowers absorb carbon dioxide and release oxygen through photosynthesis during the day, but at night, it is just the opposite. Therefore, it is best not to put flowers in the bedroom. Flowers planted during the day will be moved out at night, at least not in the bedroom, so as not to affect people's health.

Too many flowers will harm your health ... >>& gt Flowers that can't be ignored in the room.

Some medical experts have done experiments and tests, and the results show that people who often smell flowers will have a certain impact on their mood and health. Chemical experts believe that the fragrance emitted by flowers consists of dozens of volatile compounds, including aromatic esters, alcohols, aldehydes, ketones and other substances. These substances can stimulate people's respiratory center, thus promoting people's respiratory function. If people breathe the fragrance beneficial to human body, they can make the brain get enough oxygen, regulate people's nervous system, promote blood circulation, and make energy, thinking and vitality reach a very high level. Therefore, flower therapy and aromatherapy came into being.

Experts pointed out that the fragrance of flowers can not only cure diseases and protect health, but also cause diseases and harm people's health. The fragrance of flowers in the air is too strong, and the oxygen content is relatively reduced, which will stimulate people to hyperventilate, reduce the oxygen content in the blood, and cause symptoms such as headache, dizziness and nausea. Some people with allergic constitution will be stimulated by some pollen, resulting in allergic asthma and allergic rhinitis. For example, orchids can help relieve hot cough, and may also play a catalytic role. The smell of orchids is too strong, which makes people feel too excited and dizzy The fragrance of lilies is exciting, but if it lasts too long, it will make people dizzy and may also make people insomnia. 1, Dazhu (Penglai banana)
