The photosynthetic pathway of these plants is different from that of ordinary plants. They open their stomata at night, absorb carbon dioxide and store it, and release it for photosynthesis during the day. This phenomenon was first discovered in Sedum, so this photosynthetic pathway is also called Sedum photosynthetic pathway.
Question 2: What green plants give off oxygen at night? Cactus (bulbs) release oxygen at night. General plants carry out photosynthesis during the day and release oxygen; Breathing at night absorbs oxygen and releases carbon dioxide; Cactus is different from other plants. Cactus originally lived in desert and arid climate. As a result of long-term adaptation, its leaves become prickly and its stems are thick and fat to store water. The pores are closed during the day and opened at night, releasing oxygen, which is beneficial to people's health. Moreover, cactus can absorb harmful gases such as formaldehyde and benzene, and can also absorb rays emitted by computers and televisions. It is suggested to put a cactus on the computer desk. Common flower varieties that can purify night air are Phalaenopsis, Ailanthus altissima (longevity flower), Phalaenopsis, Sedum, cup-shaped rooting, pineapple cultivation and so on. , as well as reeds, Eupatorium odoratum, agave, aloe, aerial orchids (such as Phalaenopsis) and some ferns (such as bird's nest ferns).
Question 3: What is needed to release oxygen at night? The bedroom is a place where people sleep and rest, so it is appropriate to create a beautiful and quiet environment. The following points should be considered when arranging flowers:
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.

Question 4: What plants release carbon dioxide at night? Do indoor plants "take oxygen" with people at night?
Recently, Miss Qin found that the green radish at home and outside was depressed and yellow. Several "senior" flower farmers in the company said that the green radish is a subtropical plant and will be moved indoors in winter. Those flower growers also reminded Miss Qin that after winter, air conditioners, humidifiers and other equipment will gradually be used indoors, and electromagnetic radiation will gradually increase. It is suggested to plant some radiation-resistant plants, such as cactus and chlorophytum.
"If there is no light at night, will the plants moved indoors inhale oxygen and exhale carbon dioxide because they can't carry out photosynthesis?" Recently, the reporter found in several forums that many netizens posted questions. Some netizens even said that after moving a few pots of plants into the house, they felt weak and unconscious every morning. He moved the plants outside the house and all the symptoms disappeared immediately. Therefore, he insisted that all the previous feelings were caused by plants "competing for oxygen" with themselves at night, resulting in "lack of oxygen" in sleep.
Cactus will release oxygen at night.
Wu Zhixing, a senior engineer, said that the view that "plants placed indoors at night will release a lot of carbon dioxide and' take oxygen' from people" is totally misunderstood. At night, plants release very little carbon dioxide and will not "take oxygen" with people. Compared with other plants, cactus releases oxygen at night.
In addition, the latest research also shows that if 2% to 5% plants can be planted near computers and televisions, the damage of electromagnetic radiation will be reduced by 50%. If "large foliage plants" and "cactus" can be combined, the electromagnetic radiation of household appliances can be reduced and blocked to the greatest extent.
Wu Zhixing suggested that white-collar workers who are accompanied by computers and televisions all the year round should build a "green wall" indoors to avoid electromagnetic radiation because of frequent use of heating and other equipment in winter.
Ten foliage plants suitable for home cultivation
Ivy, chlorophytum, tiger tail orchid, green radish, rubber tree, brown bamboo, Brazilian wood, banyan tree, sundew, rich tree, etc.

Question 5: Which flowers also give off oxygen at night? Plants that release oxygen all day, such as cactus, tiger orchid, Sedum, aloe and chlorophytum, are jasmine, rose and cordate telosma. They have been absorbing carbon dioxide and releasing oxygen. They can release volatile essential oils and negative ions day and night, which have the functions of refreshing the air and keeping the bedroom air clean. The fragrance contained in them is refreshing and can relieve fatigue. Some floral scents can also treat chronic diseases such as depression and neurasthenia. Giant bamboo 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. Plants need to support or climb along objects when they grow up. 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 Crabapple, Crabapple, cactus, purple pineapple and torch pineapple, agave and so on. Plants that can purify the air are pomegranate, carnation, rose, rose, daisy, flying grass, sedge and so on. Indoor greening plants should be reasonably matched in order to be more conducive to our health. If the bedroom space is not large enough and the air is not ventilated enough, it is not advisable 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.
Question 6: What are the plants that release oxygen at night? Most plants absorb carbon dioxide and release oxygen during the day. At night, it's the opposite. But cactus, tiger orchid, Sedum, aloe and chlorophytum have always absorbed carbon dioxide and released oxygen.
Photosynthesis and respiration coexist in plants, each exercising its biological function and mission, and cooperating with each other. It seems that photosynthesis releases oxygen and absorbs carbon dioxide. Breathing releases carbon dioxide and absorbs oxygen. The intensity of photosynthesis determines the amount of oxygen released by plants. But it doesn't mean that photosynthesis can determine respiration. There is no absolute dependence between them. The main controlling factor of photosynthesis is light, while the main controlling factor of respiration is temperature. The respiration of plants has always existed, including day and night. Photosynthesis mainly occurs in the daytime, which determines that most plants will release carbon dioxide and absorb oxygen in the daytime and at night, but in the case of light, photosynthesis far exceeds respiration, making carbon dioxide released by respiration almost directly utilized by photosynthesis, which also shows that plants release oxygen and absorb carbon dioxide in the daytime.
For succulents, the cells of this kind of plants adopt the acid metabolism pathway (CAM) of Sedum. Therefore, it is different from other C3. C4 factory. The stomata of these plants are closed during the day, and little or no gas exchange occurs. But at night, it's different. They exchange gases through photosynthesis and respiration. Obviously, they release much more oxygen than carbon dioxide. This is very different from other plants. But this does not mean that the photosynthesis of succulents takes place at night. In fact, these carbon dioxide are stored in organic acids (such as malic acid) in mesophyll cells.
Question 7: Plants that release oxygen at night? Plants that release oxygen at night are:
Cactus: cactus, fairy mountain, cactus column, inchworm, crab claw orchid, Haohua, spirit sword, white sandalwood and so on.
Sedum: Sedum, Sedum, Sedum, Eichhornia, Yu Lian, Lycopodium, etc.
Hupilan genus: Hupilan, with more than 300 varieties of agave, tequila in Phnom Penh, aloe, African claw, Cui Hua palm, raw flower, root of rehmannia, kiwi, yucca, dwarf Galand, centennial leaf, etc.
The photosynthetic pathway of these plants is different from that of ordinary plants. They open their stomata at night, absorb carbon dioxide and store it, and release it for photosynthesis during the day. This phenomenon was first discovered in Sedum, so this photosynthetic pathway is also called Sedum photosynthetic pathway.
Question 8: Which potted plants can be kept indoors and release oxygen at night? Just now, the man said that Chlorophytum can't be kept at home, because the geomantic omen is not good and Chlorophytum is homophonic.
Question 9: Whether plants release oxygen at night or during the day mainly depends on the light.
There is plenty of light during the day, absorbing carbon dioxide and releasing oxygen.
But at night, the light is insufficient, the photosynthesis of plants is completely inhibited, and the respiration is very strong. Like people, they inhale oxygen and expel carbon dioxide.
Question 10: What plants can release oxygen at night? Plants that release oxygen at night are:
Cactus: cactus, fairy mountain, cactus column, inchworm, crab claw orchid, lotus flower, arrow, white sandalwood and other Sedum families: Sedum, Sedum, Yu Lian, Shi Lian, tiger orchid, agave, agave in Phnom Penh, aloe, African claw, Cui Hua palm, rock flower and so on.
