Why do the leaves of plants adsorb to air?

Plants not only provide food and oxygen for animals and humans, but also purify the living space around us? Can plants use light, carbon dioxide from the air and from the soil? The water absorbed in the air makes organic matter through photosynthesis and produces a large amount of oxygen, and it is precisely because plants can absorb carbon dioxide in the air and release oxygen that the carbon dioxide and oxygen in the air are in balance?

Without plants, the atmosphere will soon run out of oxygen, and with more and more carbon dioxide, animals and people will not survive?

Can plants absorb dust from the air? Some plants have rough and hairy leaves, and some can secrete mucus and oil, so they can absorb a lot of dust? After a rain, the dust on the leaves will be washed away and the leaves will regain their adsorption capacity?

Can plants reduce wind speeds, which makes the air more polluting particles? Dust falls, which plays a role in purifying the air?

The roots of the plant are tightly bound to the soil, and it is not easy to fly dust even if the wind is strong? Can some plants also absorb toxic substances from the atmosphere and reduce the amount of toxic substances in the atmosphere? Hibiscus, for example? Boxwood? Arborvitae? Loquat? Can camphor absorb chlorine from the air?

In the process of sustaining life, people must inhale oxygen and exhale carbon dioxide. When the concentration of carbon dioxide in the air is too high, a person's breathing can be difficult or uncomfortable, and it may even be poisoning. Greenplants are the only creators on earth that can synthesize organic matter from sunlight, and they are also the absorbers of carbon dioxide and the manufacturing plants of oxygen on earth.

In addition to absorbing and scavenging carbon dioxide in the air, plants also have a certain absorption capacity for harmful gases such as sulfur dioxide, chlorine and hydrogen fluoride in the air. For example, 1 hectare of cedar forest can absorb 720 kg of sulfur dioxide per year; 259 square kilometers of alfalfa can reduce sulfur dioxide in the air by more than 600 tons per year; 1 hectare of silver birch forest, which can absorb 11 8 kg of hydrogen fluoride per year; l hectare of black locust forest, which can absorb 42 kg of chlorine gas per year.

Plants not only have the effect of blocking the spread of radioactive materials, but also can play the role of filtration and absorption. For example, in the United States, scientists have used different doses of neutrons and rays to mix five oak forests and found that trees can absorb a certain amount of radioactive material without affecting the growth of trees, thereby purifying the air.

Dust is the main pollutant in the air, it is small in size and weight, and it floats around. In addition to dust and dust, dust also contains soot charcoal particles and metal particles such as lead and mercury, which often cause respiratory diseases in people. Plants, especially forests or belts composed of trees, have a canopy of dense leaves and twigs, like a dense sieve, which can act as a filtering force for blocking, retaining and adsorbing dust pollution in the air, thereby purifying the air.

It is determined that the difference in dust content in the air between the green area and the non-green area is 10 15; There is more dust in the air on the street than in places with dense trees, such as parks, l 3 2 3. However, the dust reduction capacity of different tree species is different, and the test results show that the dust reduction capacity of broad-leaved trees is higher than that of conifers, and the dust reduction capacity of 1 hectare of spruce is 32 tons per year.

The purification of the air by plants is to turn the polluted air into fresh air without pollutants or with less pollutants through the physical effects of blocking, retention, adsorption and other physical effects through the absorption and accumulation functions of plants. Although different plants have different purification capabilities for different pollutants, the ability to purify the air depends on the group action of plants. Therefore, in order to make the air of a city or a factory clean and beneficial to people's life and health, in addition to selecting tree species for afforestation and greening according to the substances and concentrations of polluting air in factories and cities, a certain proportion of green space is also needed.

There are many benefits of potted plants at home, one of which is to purify the air, and the ability of many flowers and plants to purify the air is superb!

1.Repel insects and reduce fire.

Potted some herb plants indoors, keep warm and moist to keep plenty of water, only need a little scattered light they can grow well, vanilla plants have a strong fragrance, these herb plants have a good mosquito repellent effect, such as mint, bumper incense, etc., of course, mint can also be used to make tea, as well as to cool off the heat.

2.Increase oxygen levels.

Potted flowers and plants can also increase the oxygen content for the room, they photosynthesize and continuously release oxygen, increase the indoor oxygen content, improve air quality, we should choose some plants that can release oxygen 24 hours a day, such as longevity flowers, cacti, tiger pill orchid, sedum succulents, etc., they can also increase indoor negative ions.

Choose indoor purifying air plants are:Spider plant: Spider plant is not only beautiful, but also has a particularly good effect of adsorbing toxic gases. Even in an unrenovated room, raising a pot of spider plants is also beneficial to people's health.

Aloe vera: Aloe vera has a certain odor absorption effect, and also has the effect of beautifying the room.

Cactus: Most plants absorb carbon dioxide and release oxygen during the day, but the opposite is true at night. However, cacti, tiger pill orchid, sedum, aloe vera and spider plant have been absorbing carbon dioxide and releasing oxygen.

Peace Tree: At present, large plants such as peace trees and camphor trees are more popular on the market, and they can release a fresh gas that makes people feel happy.

People and animals breathe fresh air, the environment will be better, the earth will be more beautiful...

Plant purification is the harmlessness of pollutants entering the environment through metabolism (alienation and assimilation), including the purification of air pollution by terrestrial plants and the purification of water pollutants by aquatic plants. Plants purify the atmosphere mainly through leaves, and their main functions are: Absorb CO2

Releases O2; It has a retention and filtration effect on dust and dust; Within the resistance range, it can reduce the content of harmful gases such as SO2, HF, Cl2, and O3 in the air by absorption; In the resistance range, it can reduce photochemical smog pollution; filtration or bactericidal effect; It has the effect of absorbing and purifying heavy metals in dust and particulate matter; Reduction of noise contamination and radioactive contamination. Some aquatic plants have a good absorption and purification effect on pollutants in the water body, and are used to treat sewage. For example, Phragmites conmunis and rice grass (Spartina anglica) have certain purification capabilities for suspended solids, chlorides, organic nitrogen and sulfates in water. Shallot (scirpus validus) can purify phenols in water; Eichhornia crassipes, duckweed (Lemna minor), goldfish algae (ceratophyllum demersum), black algae (hydrilla verticillata) and so on have the effect of absorbing heavy metals in water. Pull.

Garden plants inhale pollutants in the atmosphere into their bodies through the stomata on the epidermis, and go through the process of redox in the body, turning the original toxic substances into non-toxic substances, excreting them from the body through the root system, or accumulating and storing them in a certain organ. The absorption, accumulation and discharge of air pollutants by plants play a role in purifying the atmosphere. My personal opinion, I hope it can help you.
