What are the benefits of green plants for humans?

Since ancient times, plants have been silently improving and beautifying the living environment of human beings. In the plant kingdom, there are about 7,000 species of plants that can be eaten by humans, and many of them have miraculous healing properties. There are about 5,000,600 species of folk herbs, and 40 per cent of modern medicines come from nature.

Scientists also extract anti-cancer substances from plants such as Mayden wood and yew, and their curative effects are very obvious. Green plants are the pillars of ecological balance, because plants can purify sewage, eliminate and reduce noise, tolerate drought and sand fixation, resist salinity, waterlogging, and monitor pollution from sulfur dioxide, fluorine, chlorine, ammonia, etc. Green plants rely on photosynthesis to sustain growth, absorb carbon dioxide, and release life-sustaining oxygen from humans.

According to the survey, there are more negative oxygen ions in the air in the forest area, and after inhalation into the human body, it can regulate the excitatory and inhibition process of the cerebral cortex, improve the body's immunity, and have curative effects on chronic bronchitis, insomnia, etc. There are also many plants that can secrete fungicides to kill surrounding germs, such as eucalyptus, which can kill tuberculosis bacteria, pneumonia bacteria, etc. A pine tree can secrete 2 kilograms of fungicide in one day and one night, which can kill diphtheria, dysentery and other germs.

Rain and dew moisten the seedlings and grow, and all things depend on the sun for survival. The beautiful environment comes from the first, and the green leaves of the plants are miraculous. Here we will talk about the important role that green plants play in the earth's environment, especially the urban environment, on which human beings depend.

Plants are the best materials for greening and beautifying urban and rural areas. The colorful flowers of the plants and the fragrance of many plants give people a pleasing and relaxing feeling. For example, the scent of chrysanthemums is good for headaches, dizziness and colds.

In addition, the fresh air in green spaces and forests is rich in negative oxygen ions, up to more than 20,000 per cubic meter of air in the forest, and only 40-50 in the indoor air in the city. Negative oxygen ions can give people a fresh feeling and have a certain effect on lung disease. According to the survey, where the environment is green, the accident rate can be reduced by 40%, and the work efficiency can be increased by 15-35%.

A beautiful environment can also be a great inspiration for creativity.

1. Green plants convert solar energy into organic matter such as starch and lignin.

etc., to provide food for animal microorganisms.

2. Green plants absorb carbon dioxide.

and release oxygen. It provides animal microorganisms with oxygen for respiration.

3. Green plants provide a large number of building materials and various materials for life and production for human beings.

4. Green plants absorb red light and a lot of heat from the sun, which can effectively reduce the temperature.

5. Green plants absorb and release water deep underground into the air, which can improve the regional environment.

Ways to protect greenery:

First, it is a reasonable plan, delineate the green plant development area, and gradually expand the area of green plants.

Second, it is to strengthen fertilizer and water management, apply enough fertilizer, achieve balanced fertilization, reasonable water supply, and promote the growth of green plants.

Third, it is to strengthen the prevention and control of pests and diseases to ensure the healthy growth of green plants.

Fourth, it is to strengthen management and protection to avoid trampling or destruction by humans and animals.

Fifth, it is the establishment of special protected areas, mainly referring to the green plants protected by the state.

1. Synthetic organic matter.

The net annual production of all plants on the planet is about 150 billion to 200 billion tons of organic matter, which is the basic material on which humans and heterotrophs around the world depend.

2. Oxygen production function.

It has been determined that 750 kg and 600 kg of oxygen are released per day per hectare of forest and park green space respectively in summer. More than 100 billion tonnes of oxygen are released annually by the world's green plants.

3. Wind prevention and sand fixation.

Shelterbelts can be built in wind-damaged areas, and the wind speed can be reduced by about 30% within the protection range; Farmland with shelterbelts has about 20% more yield than those without.

4. Regulate the climate.

In summer, the ground temperature in the green space is generally 10-17 degrees lower than that in the white ground in the square, and 12-22 degrees lower than the asphalt road; In winter, the average surface temperature of the lawn is 3-4 degrees higher. According to statistics, the average rainfall in woodlands is 16-17% higher than that in non-forested land, and the lowest is 3-4% more.

5. Maintain soil and water.

Scientists have observed that soil erosion is reduced by 60% in 30% forest land compared with non-forest land. Observations of mountainous land with a slope of 13 degrees have also revealed that the amount of soil and sand lost each year is 48 times that of bare land and that of forest land.

6. Absorb poison gas.

More than 300 species of plants have been found to secrete volatile fungicidal compounds, such as fresh peach leaves to repel bed bugs; The smell of cucumbers can make cockroaches flee; Onion and tomato plants repel flies; Woody nightshade or basil repellent mosquitoes.

Green plant role:

In terms of greening:

Green and other ornamental plants can be used for greening, creating a fresh and comfortable environment, and as street trees to absorb dust.

Environmentally:

Other plants such as green can absorb CO2 and release O2 from the environment under suitable photosynthetic conditions such as sunlight, temperature, and CO2 (at night, they will also respire and release CO2 due to lack of sunlight).

At the same time, the green plants around the hospital and the factory usually have the functions of purifying the environment, resisting and disinfecting, and absorbing toxic gases, and some green plants can reduce radiation (cactus family) and purify formaldehyde (tiger tail orchid, monstera, ivy, iron fern, weeping ficus) and so on.

In terms of health care: there is now a kind of "gardening" and refers to an effective method for people who need to improve their physical and mental aspects through the environment and horticultural operations in the garden, and most of the horticultural plants are green ornamental plants.

1. Green plants convert solar energy into organic matter such as starch, lignin, etc., which provide food for animal microorganisms.

2Green plants absorb carbon dioxide and release oxygen. Provide the microorganisms in animal clothing with the oxygen they need to breathe.

3. Green plants provide a large number of building materials and various materials for life and production for human beings.

4. Green plants absorb red light and a lot of heat from the sun, which can effectively reduce the temperature.

5. Green plants absorb and release water deep underground into the air, which can improve the regional environment.

The roles of plants are: photosynthesis, respiration, absorption, transpiration, and transport.

1. Photosynthesis:

Green plants use light energy to convert carbon dioxide and water into energy-storing organic matter, mainly starch, and release oxygen. Note: From the raw materials of photosynthesis, water, carbon dioxide and warm cherry lead, consider how to enhance photosynthesis and photosynthesis conditions, places, raw materials, and products.

2. Respiration:

Respiration consumes oxygen, releases carbon dioxide, and energy is a retraction experiment and a method to promote plant respiration and inhibit respiration for recall.

3. Absorption:

When the concentration of root hair cell fluid is greater than the concentration of the surrounding soil solution, the cell absorbs water; The principle of water lossWhen the concentration of the cell fluid of the root hairs is less than the concentration of the surrounding soil solution, the cells lose water.

4. Transpiration:

The water of the plant body is transpired through the stomata of the leaves in the form of a spine of water vapor. It can lower the temperature of the plant body; Promotes the absorption of water by the roots from the soil and the rise of water from the roots to the leaves.

5. Transportation function:

Ducts (located in the xylem of the stem): transport water and inorganic salts from the bottom up.

The role of green plants: absorb harmful gases and release beneficial substances; regulating climate change and curbing global warming; provides food for human survival; provided the conditions for human evolution; Reducing noise pollution in urban areas; The basic conditions of biodiversity are maintained; Protecting human vision health; Some green plants have a certain disinfection and sterilization effect.

Green plants refer to non-unicellular plants that contain chlorophyll. It can usually be understood as a green plant. Chlorophyll in the leaves and stems of green plants can carry out photosynthesis, which is essentially the release of oxygen and energy when carbon dioxide and water are converted into sugars.

In order for animals to consume oxygen and exhale carbon dioxide, they must rely on green plants to photosynthesize to maintain the balance of oxygen and carbon dioxide in the earth's atmosphere. The vast majority of human food comes directly (grains, vegetables, fruits) or indirectly (meat) from green plants. Oil, coal, and natural gas, which account for the vast majority of human energy, also come mainly from ancient green plants.

Wood is used to build houses, cotton and linen are used to make clothes, and many plants can be used directly into medicine or extracted from them to make medicines. All in all, human life is absolutely inseparable from green plants. Green plants are trees, grasses, algae, etc.
