1, you can put some small and medium-sized plants, such as asparagus, chlorophytum, Commelina communis, ivy, radish, taro and so on.
2. Some flowers with elegant fragrance are also ideal choices. The fragrant oil secreted by flowers contains a variety of bactericidal substances, which are beneficial to human health, can also make people feel calm and happy, and is conducive to promoting sleep. For example, chrysanthemum can cure headaches; Jasmine can reduce the heat in summer and make people feel "cool when it is hot"; Both rose oil and jasmine oil have strong bactericidal ability; Osmanthus fragrans has antiasthmatic, antitussive, anti-inflammatory and antibacterial effects. Geranium geranium oil has sedative effect, can improve sleep and treat neurasthenia; In addition, gardenia, orchids, wintersweet, Milan, narcissus and so on. Are fragrant and pleasant fragrant flowers.
3. If the bedroom space is not large enough and the air is not circulating enough, it is not appropriate to place too many plants. Because plants stop photosynthesis at night and continue to breathe, they have to inhale oxygen and release carbon dioxide like people, thus increasing indoor exhaust gas and reducing fresh air, resulting in a situation of competing with people for oxygen. Some succulents native to tropical arid areas can be raised, and their photosynthesis mode is completely different from that of ordinary plants. They only open their pores at night to absorb carbon dioxide. During the day, the stomata are closed to reduce the loss of water. This kind of plants not only absorb carbon dioxide at night, but also absorb and digest the carbon dioxide produced by themselves during breathing, and do not discharge it to the outside world, thus making the air fresh. There are more than 300 kinds of flowers that can purify the air at night, and the common ones are Hupilan, Huweilan, Tongweilan, Pineapple, Aloe, Sedum (Yushu), Longevity, Palmae and so on.
With the improvement of people's living standards, the requirements for indoor air quality are getting higher and higher. However, due to decoration and other reasons, there are thousands of harmful substances in the indoor environment, among which radon, radioactivity, formaldehyde, benzene, ammonia, polyvinyl chloride, nitrogen oxides and carbon oxides are the most important and common. In addition, the increase in the use of electrical appliances has reduced the number of negative oxygen ions indoors. Planting flowers can not only beautify the environment and enliven the atmosphere, but also purify the air and eliminate indoor harmful substances. But some flowers have negative effects on people, so we should pay attention to them.
It is reported that plants such as Zi Yuan, Astragalus membranaceus, tobacco and Celosia cristata can attract a large number of radioactive nuclides such as uranium; Aloe, chlorophytum and Eupatorium adenophorum can remove formaldehyde; Ivy, rose, rose, aloe and evergreen can effectively remove trichloroethylene, sulfur specific hydrogen, benzene, phenol, hydrogen fluoride and ether indoors; Pigeonpea, Phyllostachys pubescens and Eupatorium adenophorum can absorb more than 80% of indoor harmful gases; Asparagus can remove heavy metal particles; Citrus, rosemary and chlorophytum can greatly reduce bacteria and microorganisms in indoor air.
In addition, chlorophytum can effectively absorb carbon dioxide; Some fleshy flowers of cactus rarely emit carbon dioxide at night; Wisteria has strong resistance to sulfur dioxide, chlorine and hydrogen fluoride, and also has certain resistance to chromium. Some leafy and water-loving plants, such as radish, can keep the indoor air humidity in an excellent state.

Growing flowers in the house has many advantages.

Pay attention to the flowers in the bedroom.
Although raising flowers at home has many advantages, we should pay attention to the arrangement of flowers in the bedroom, because flowers release oxygen and absorb carbon dioxide during photosynthesis during the day; But at night, flowers do not carry out photosynthesis, not only spit out carbon dioxide, but also absorb oxygen. At this time, if flowers are placed in the bedroom, it will be harmful to health; Therefore, in the bedroom, it is best to put less or no flowers at night to avoid them competing for oxygen and affecting health.
Some flowers can not only freshen the air, but also have some negative effects on people, so it is best not to put them in the bedroom. For example, although Chinese rose can absorb a lot of harmful gases, its rich fragrance will make people feel depressed and uncomfortable, hold their breath and even have difficulty breathing; Rhododendron, tulip, lily, poinsettia, etc. can also absorb volatile chemicals, but Rhododendron flavum contains a toxin, which can lead to poisoning and shock in severe cases (not for sale in the market), but most Rhododendron contains some volatile oil and azaleas, which have certain curative effects on tracheitis and asthma. On the other hand, tulip flowers contain a toxic alkali, which is reported to accelerate hair loss when exposed for too long;
The fragrance of lily, if smelled for a long time, will make people's center excessively excited and cause insomnia.
There are also some flowers, such as the pollen of Bauhinia, which can induce asthma or aggravate cough when exposed for a long time. Mimosin in mimosa is a very toxic organic substance, and excessive contact with human body will cause hair loss; Nose-stimulating particles emitted by cordate telosma at night will make patients with hypertension and heart disease feel dizzy, depressed and even worse. However, cordate telosma is an ornamental fragrant flower, and its rich aroma can repel mosquitoes, which is generally used in courtyards and balconies.
Those flowers are suitable for the 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, Chinese rose, camellia, pomegranate, Milan, daisy, Chimonanthus praecox and calendula can effectively remove sulfur dioxide, chlorine, ether, ethylene, carbon monoxide and peroxide. Diarrhea?
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.
Those flowers don't fit in the bedroom;
(1) Flowers that should not be kept indoors for a long time. Pine and cypress plants, such as a large number of indoor plants, will release a strong rosin, which will affect people's appetite and make pregnant women feel sick. Geranium can cause allergic reactions in some people; Tulip flowers contain toxic alkali, which will make people dizzy and make their hair fall off if exposed for too long. Cordate telosma emits a lot of waste gas when it stops photosynthesis at night, which will make patients with hypertension and heart disease feel depressed; Jade cloves are put indoors for a long time, giving off peculiar smell, and some people will cause asthma and boredom; The smell of elderberry can also make people sick and dizzy. Therefore, the flowers listed above should not be placed indoors for too long.
(2) poisonous flowers:
(1) Rhododendron flavum, plants and flowers contain toxins, which can be poisoned if eaten by mistake.
(2) Poinsettia, the whole plant is poisonous, and the white juice can stimulate the skin to be red and swollen, and eating the stems and leaves by mistake is in danger of poisoning and death.
3 oleander, branches, leaves and bark all contain oleanolide, and eating a few grams of dry matter by mistake can cause poisoning.
(4) Light leaves are succulent plants, and the white juice from broken stems can make the skin red and swollen, which can cause blindness if eaten by mistake.
⑤ Five-colored plum, with poisonous flowers and leaves, can cause diarrhea and fever if eaten by mistake.
⑥ Narcissus and bulbs contain lacodine, which can cause enteritis and vomiting if eaten by mistake. The juice of leaves and flowers will make the skin red and swollen.
⑦ Lycoris radiata and bulbs contain lycorine and other toxic substances. Exposure to lycorine can cause redness and itching. Lycorine inhaled into respiratory tract can cause nosebleeds, vomiting, diarrhea, cold hands and feet, shock, and even death due to central nervous system paralysis.
8 mimosa, the body contains mimosaponin, too much contact will make people's hair fall off and eyebrows sparse.
Pet-name ruby thorn plum, overlord whip, the white milk in the stem is toxic and can't enter the eyes.
Attending the leaves, flowers and leaves of Evergreen contain oxalic acid and asparagine, which will cause swelling and pain in the mouth, throat, esophagus and stomach, and even hurt the vocal cords, making people dumb.
⑾ The prickles of cactus plants contain poisonous juice, and allergic symptoms such as redness, pain and itching are easy to appear after being stabbed.
⑿ coral bean, the whole plant is poisonous. Children should be educated not to eat its red fruit.
