It can not only beautify the environment, absorbing carbon dioxide, oxygen, and also with the absorption of other harmful gases, dust adsorption, sterilization, regulating climate, sound absorption in dry, sand-fixing and monitoring of air pollution and many other aspects of the role. Accomplished through the following means, first, absorption, adsorption of pollutants, followed by the product, decomposition, transformation of pollutants, the other is to change the environment, prevent environmental degradation, which is in many other species can not be replaced. Therefore, the strong work of planting trees, grass greening activities.
plants have the role of dust, more importantly, the plant can absorb the atmosphere of the compounds or toxic chemicals. Retention of the process involved in plant interception, absorption, retention, etc., removal process, including plant uptake, degradation, transformation, assimilation. Plants for the adsorption and absorption of pollutants occurs mainly in the aerial part surface and leaves the pores. Adsorption is a physical process, with the plant surface structures, such as leaf morphology, roughness, and leaves a raw surface of the discharge point on. Plants can absorb the atmosphere of a variety of chemical substances, including co2, so2, cl2, HF, heavy metals (Pb) and so on. Plants to absorb pollutants in the atmosphere mainly through the stomata and through the plant vascular system to transport and distribution. Plants in the spring and autumn absorption ability of different plants absorb different pollutants have a greater difference in ability.
plants to maintain the balance of oxygen and carbon dioxide plays a very important role. It is the ecological environment of the major producers of oxygen, but also a major consumer of carbon dioxide. Carbon dioxide is the main raw material of plant photosynthesis. Carbon dioxide on plant growth and development has an important role.
plants absorb carbon dioxide and release oxygen in photosynthesis, but also absorb oxygen through respiration and release carbon dioxide. However, due to photosynthesis than respiration of carbon dioxide absorbed by carbon dioxide emissions more than 20 times, therefore,UGG boots, calculated the total consumption of carbon dioxide in the air, an increase of oxygen in the air. 1g glucose formed leaves of plants need to consume the carbon dioxide contained in the air 2500L. 1kg of glucose formed, it must absorb the 2.5 million liters of air contains carbon dioxide. According to the determination often leaves broad-leaved forest 1 hectare, the annual release of 20 ~ 25t oxygen, 1 hectare of coniferous forest 30t annual release of oxygen. Hectares of broadleaf forest in the growing season, one can absorb through photosynthesis 1t co2, release 0.73t o2. To the needs of an adult 0.75kg o2 oxygen discharge 0.9kg co2 will each be 10 square meters of forest area can be excluded from consumption of the respiratory carbon dioxide, and supply the necessary oxygen. About 150 square meters of plant leaf area to meet the needs of an adult of oxygen. A good lawn growth, during photosynthesis, the absorption of 1.5g per hour per square meter of carbon dioxide, exhaled carbon dioxide per person per hour is about 38g, therefore, 25 square meters of lawns during the day a person can exhale carbon dioxide absorbed. Coupled with the increase in plant respiration evening of carbon dioxide, the lawn area of 50 square meters per person can maintain the balance of carbon dioxide.
plants to absorb harmful gases are mainly carried out by the blade. Leaf area is larger, the stronger the purification capacity, leaf area is proportional with the purification ability. Tall, 1 hectare of forest, the leaf area of 75 hectares; 1 hectare of lawn, an area of 22 to 25 hectares. Strong resistance to the harmful gases, absorbing a large quantity of plants to air pollution is more serious in the areas of persistent growth, and to play its purification.
absorption ability of sulfur species (ie, 10mg 1g dried leaves can absorb more sulfur) are weeping willows, Populus, Fraxinus Liu, Shan residue, acacia, Ailanthus, elm, apple, acacia, peach, Blue Eucalyptus, Euonymus, cloves, dry cypress, Jujube, Rose, Ash, Populus, water elm, oleander and so on.
forsythia, acacia, acacia, gingko and other gases produced by chemical smoke, strong absorptive capacity.
smell of chlorine and other people have a strong yellow-green gas asphyxiation, is a strong oxidant and can absorb ultraviolet radiation in the air. A chemical, pharmaceutical and pesticide factory. Chlorine on human upper respiratory tract, eyes and skin with nasal irritation, long-term activities with the chlorine in the environment, but the increased incidence of chronic bronchitis, is corrosive to the teeth.
Gleditsia 80 kg, 42 kg black locust, willow 9 kg. Strong resistance of plants to purify the air can play a role. High levels of absorption of chlorine species are Beijing, peach, apricot, sugar maple, elm family, Tilia,
urban air pollution is the biggest in the motor vehicle emissions, accounting for total emissions of urban air pollution 88 %, followed by incineration with solid waste and industrial production. Pb steam plants can absorb, leaf through the stomatal breathing can lead vapor The absorption of pollutants degradation, 7 pb with the amount of species of forest trees: elm, pomegranate, black locust, privet, Euonymus japonicus.
ammonia, relative molecular mass of 17.03, is a colorless gas with a pungent odor, such as: soybean, sunflower, corn and cotton. Particular line of Flower Branch butterfly plant, can directly absorb the ammonia in the air.
tribute gases have significant toxicity, but some plants not only in tribute grow well under steam environment, free from hazards, and can absorb some of the contribution of steam. Palm, which are strong enrichment ability of tribute, to effectively reduce the contribution of vapor in the air.
measured in an area of Shanghai on the contribution of the absorption of the following plants are: palmitic 84, Sakura 60, Euonymus 52, 22 Hydrangea, Canna 19.2, Bauhinia 7.4, 6.8 magnolia, bay 6.8, 5.1 Osmanthus , coral tree, 2.2, 1.4 bloom.
cork maple, cinnamon Liu, Yang and trees can absorb the increase in the air aldehydes, ketones, alcohols, ethers and benzoin Pyrazoline and other toxic gases.
plants,UGG boots clearanc, especially trees, the atmosphere of smoke and dust have great blocking, filtering and adsorption, the role of forests in reducing dust in two aspects: first, the dense forest canopy, with a strong reduction wind effect, as the wind speed decreased, the air carrying the dust and dust quickly landed the larger leaves of trees or the ground; the second surface of the leaves of different trees of different structures, some of the rough surface, hairy plants, some plants also secrete sticky leaf oil and juice, particles in the air after the trees, they were attached to the leaves and branches on. So plants can absorb large amounts of floating dust. Trees is known as natural air filters. After rain washed the dust and can restore its adsorption capacity. Leaf surface area of the plant itself covers an area of typically more than 20 times, so the tree is a great Dust.
50 grams / square meters of hardwood trees are paulownia, myrobalan plum, Prunus triloba, Celastraceae, dust in the 10 to 30 grams / square meter of trees within the tree of heaven, Sophora japonica, mountain buckwheat, purple Ye fruits, Euonymus japonicus, Rhus typhina, dust content of 10 g / m below the ginkgo tree, ash,UGGs, willow, plane, elm, black locust, poplar, crabapple, forsythia, lilac, Wool daisy, pearl plum, peach, honey locust, Acer mono, honeysuckle and so on.
dust plant trees in the 10kg more than the amount of species there are plane trees, Ailanthus altissima, Paulownia, plant trees in the amount of dust species in the 5 ~ 10kg with ash, Sophora japonica,, plant trees dust volume in 1 ~ 5kg Euonymus species are, torch trees, honeysuckle, lilac and so on.
planting trees and grass, to avoid bare soil, in landscaping, it is also an effective measure to reduce pollution. When dust in the choice of species, total leaf area, rough hairy leaves that secrete sticky grease or juice pulp trees such as walnut, poplar,cheap UGG boots, Chinese chestnut, Ailanthus altissima, arborvitae, pine, acacia, paulownia, are all better dust species. Cotton grass, Bermuda grass, buffalo grass, Festuca spear, black and so is a good lawn dust buckwheat plants.
the particles in the air with a lot of bacteria, many of them, or harmful bacteria. Bacillus 37 species of bacteria 26 species of filamentous fungi, 20 species of blastomycosis 7 species, in addition to a variety of bacteria. Less dust in the atmosphere, less the number of bacteria, which is due to the role of green plants by dust, thus reducing the bacterial content of the air. Some trees also secrete volatile bactericidal substances, namely phytoncide, such as eugenol, resin, cinnamon oil, has a bactericidal capacity. Some bactericidal ability of species such as black walnut, plane trees, crape myrtle, pine, tree, in cedar leaves, etc. can be crushed within a few minutes to kill protozoa. Onion, minced garlic paste can kill staphylococcus, streptococcus and other bacteria. Pearl plum out of spinosad volatile gold color aureus, Pseudomonas aeruginosa, the bactericidal rate of 100%, and most capable system Disease Mycobacterium bovis and some soil-type acid-fast Mycobacterium tuberculosis has a very strong bactericidal effect, are stable. Thyme oil, clove powder, geranium oil, lemon oil, the bactericidal effect.
people at home an average of 66% of the time, plus the time in the office, time spent indoors totaled 94%. Indoor air quality is directly related to people's health. Seal of the house, ventilation rate is very low, indoor residential renovation, formaldehyde or solvents with serious pollution, has posed a threat to human health. NASA specifically for the development of living environment, the system carried out indoor air pollution. Through a variety of biological functions of research, concluded that the purification capacity of indoor foliage plants the most.
leaf stomatal foliage plants can strongly absorb the atmosphere of formaldehyde. Human health hazards of formaldehyde is very large, but widely produced in the resultant fuel, cooking fumes, poor decoration materials and various daily chemicals, drilling days, Yang, Robinia pseudoacacia, Acer palmatum absorption rate of formaldehyde was also high. In addition, the more adequate light, the higher the absorption rate of formaldehyde. Photosynthesis in plant leaves in the process and decomposition of formaldehyde is also being absorbed. Purification ability of plants to use sources break down into harmless substances.
raise some of the best indoor plants, such as Monstera, which put a lot of room to absorb CO2,, In addition, cactus, cactus, authority arrow, Epiphyllum and other cactus plants, orchid variety of orchids, stone garlic Section Clivia, Narcissus, Sedum Bauhinia others have this strange feature. Canna has a strong absorption of SO2 performance. Put a two basins in the indoor air of pomegranate can reduce the lead content, but also to absorb S, HF, Hg and so on. Carnation has the ability to absorb the SO2 chloride. Rose, rose to more absorption of H2S, HF, phenol, ether and other harmful gases. Spider plants, aloe can eliminate formaldehyde contamination. Crape myrtle, jasmine, lemon and other plants that can kill the native bacteria, such as diphtheria bacteria, dysentery monocytogenes. Jasmine, rose, carnation, lily of the valley, violet, rose, osmanthus and other plants emit the smell of Mycobacterium tuberculosis, pneumococcus, staphylococcus, etc. significantly inhibited the growth and reproduction. Tiger Piran, Sansevieria, agave and brown hair palm, pineapple cultivation in the night air purification. Orchid, osmanthus, red back Gui is a natural filter, the cilia can intercept and absorb particles floating in the air stagnation and fine dust. and bark of trees
oil purification of air pollution in addition leaves
purify air pollution effects, essential oils and bark of trees, ammonia, sulfur dioxide, ammonia and other air pollution dioxide with clearance.
Ye Youqing addition to higher than wood oil. In general, the leaves more oil with low boiling point components, the Frosty fir and cedar removal rate, can be used cedar leaf oil and other plant-based ingredients manufacturing formaldehyde trapping agent, in the trapping of formaldehyde at the same time, but also the release of volatile aroma.
