What are the benefits of big trees for people Please kiss

First, it can produce oxygen; second, beautify the environment; Third, it's good to enjoy the shade under the big tree! Three come to mind for the time being.

Produce oxygen, beautify the environment, prevent desertification of the land, control global heating and cold, and you can also dry bacon bars on it, and make swings from tree branches

purify the air; Releases anions to balance the body's cations, which is beneficial to health.

It can beautify the environment, absorb carbon dioxide, make furniture, and fruit trees can also make everyone eat delicious fruits. Only so much can be thought of.

1) Children's favorite, climbing trees is fun.

2) Teachers also love, essay topics.

3) Passers-by also love it, you can enjoy the shade.

4) The old man also loves, chatting and playing chess.

5) Couples also love and go on a date at night.

6) Merchants love more, logging to make money.

It can be used as firewood.

Our lives are basically inseparable from trees, we eat fruits, drinks, coconut oil for stir-frying, olive oil, traditional Chinese medicine for healing, housing and furniture, school supplies, paper, man-made fibers for wearing, sightseeing, living environment... Too much is made of wood, or extracted from trees, or produced by trees. Without trees to absorb carbon dioxide, we humans would have perished, without trees to cover the land would have dried up and cracked, without the nourishment of trees, animals would have been extinct, and even we humans have evolved from trees to the ground. The world has trees, and we humans have it.

Animal and plant town Animal and plant encyclopedia early to learn and know early.

1. Adjust the climate, after the tree has passed photosynthesis, it can absorb carbon dioxide, but also spit out more oxygen, and keep it clean and fresh. 2. Wind and sand fixation, big trees can nourish water and soil, and can also absorb a lot of dust. 3. Reduce noise pollution and better reduce the decibel level of noise.

4.Kills bacteria, trees.

The role of trees.

1. Photosynthesis, absorbing carbon dioxide and releasing oxygen.

2. Transpiration, regulating air humidity.

3. Fix the soil and prevent soil erosion.

4. Barrier function, wind and sand.

5. Increase greening and beautify the environment.

6. Appreciating the value of beauty and increasing the artistic component.

7. Industrial value, wood, wood carving and other wood products.

8. Medicinal value, made into medicinal materials.

9. Trees can reduce noise pollution. A 40-metre-wide forest strip can reduce noise by 10-15 decibels

10. Tree secretions can kill bacteria. There are thirty or forty thousand bacteria per cubic meter of air in the clearing, and only three or four hundred in the forest.

Conserve water sources, prevent wind and sand fixation, regulate the climate, and purify the air.

1. Trees can regulate the climate and maintain ecological balance, and trees inhale carbon dioxide and exhale oxygen through photosynthesis, so that the air is clean and fresh. One acre of forest releases enough oxygen for 65 people to breathe for a lifetime.

2. Trees can prevent wind and fix sand, conserve water and soil, and can also absorb all kinds of dust, and one acre of forest can absorb 20-60 tons of dust a year.

3. Forests can reduce noise pollution. A 40-metre-wide forest strip can reduce noise by 10-15 decibelsNoise pollution has caused great harm to human life, study, work, rest, etc., and can be said to be people's "enemy".

Therefore, we should pay more attention to afforestation. Noise can also make human beings lose hearing, become deaf, stupid, and have abnormalities in the heart, blood pressure, and nerves in long-term life. It can even make people die under the torment of long-term noise. This way the trees make the noise less.

Four, five times. 4. The secretions of trees can kill bacteria. There are 3,40,000 bacteria per cubic meter of air in the open space and only 300-400 in the forest. Afforestation is the duty of every citizen, and the state has also designated March 12 as Arbor Day.

Afforestation is of great benefit to our study, work, and life.

5. Trees can lower the temperature and increase the humidity. The temperature of 30 degrees can drop to about 20 degrees.

6. The empire of flowers and trees not only produces us food, wood, housing and work, but also the key to the empire of flowers and trees is the great environmental benefits of the empire of flowers and trees to the natural environment on which human beings depend. It is impossible to do anything else; There is no substitute for anything else.

7. Flowers and trees can adjust the climate, purify indoor air, prevent wind and reduce noise, and avoid soil erosion, landslides and other flood disasters, and are CO2 production plants. 1 acre of broad-leaved trees can digest and absorb 1 ton of carbon dioxide in 1 day and release it.

tons of CO2. 8. Flowers and trees are smoke and dust filtering devices. When a cyclone with a large amount of smoke and dust passes through the mountain forest, the smoke and dust with large particulate matter in the air will decrease rapidly as the wind force decreases. In addition, some flowers and trees have plush skins or can metabolize vegetable oils, which can stick to the body of soot and reduce the dust content of cyclones passing through mountains and forests.

1 Careful care and proper pruning are good for large trees.

2 Careful care can include keeping the soil moist, fertilizing and weeding, etc.; Proper pruning can help keep kenai trees healthy, used to prevent pests and diseases, maintain their form and increase productivity.

3 In addition, the proper selection of tree species and the appropriate planting location are also good for large trees.

The choice of tree species should take into account factors such as the size of the tree, environmental adaptability, and pests and diseases, and the planting location should take into account factors such as sunlight, soil, and wind direction.

Only by taking into account the above factors can we provide the best environment for the growth of the tree, and pure spring will help it grow stronger.

Formula 1).

1. Trees, flowers and plants are oxygen manufacturing plants.

People are constantly inhaling oxygen and releasing carbon dioxide. Without oxygen, all life would die. The amount of carbon dioxide in the atmosphere is usually when the concentration in the air reaches that makes people feel uncomfortable breathing.

Normally, one hectare of trees can release 730 kilograms of oxygen per day and absorb about one ton of carbon dioxide through photosynthesis; Each hectare of lawn releases 650 kilograms of oxygen and absorbs 900 kilograms of carbon dioxide per day. An adult needs about kilograms of oxygen to breathe and emits about 1kilogram of carbon dioxide every day.

2. Trees, flowers and plants are the regulators of climate.

Trees, flowers and plants have the functions of heat absorption, shading and water evaporation. The results show that when the urban temperature is 22 24 in summer, the temperature under the shade of trees in the woodland is 3 5 lower than that in the place without green space, and about 10 lower than that in the building area. The air humidity in the woods is generally 7 14 higher than in the open areas; Trees can reduce wind speed.

3. Trees, flowers and plants are natural vacuum cleaners.

Dust in the air and factory dust are substances that are harmful to people. Dust into the lungs, easy to suffer from tracheitis, pneumoconiosis and other diseases on the ground of a hectare of the general city, about 3 tons of dust fall in a year, and trees, flowers and plants have a strong adhesion to the dust, trees and leaves, on the one hand, can reduce the wind speed, so that large particles of dust fall, on the other hand, the stomata of the leaves, fluff and secreted mucus can absorb or stick a large amount of fine dust.

In general, the amount of dust in green spaces is 1 5 2 3 less than in streets. The air dust content of lawn and unpaved lawns is reduced by 2 3 5 6. Each hectare of Pinus tabuliformis forest can absorb more than 30 tons of dust per year.

4. Trees are a purification ground for toxic gases.

Some industries produce some toxic gases in the production process, which will cause serious pollution to the environment. For example, sulfur dioxide, when the concentration in the air is 1/100,000, can cause asthma and pulmonary edema; When it reaches 1-4 per 10,000, people's lives are in danger. Hydrogen fluoride is 20 times more harmful to humans than sulfur dioxide.

When chlorine is 3 milligrams per liter in the air, it can cause death in humans and animals.

Some trees have some capacity to absorb sulphur dioxide. As long as the sulfur dioxide in the air is kept at a certain limit, the leaves of the trees will not be harmed, and they can continue to absorb it, which has a purifying effect on the air. For example, one hectare of cedar forest can absorb 720 kg of sulfur dioxide per year.

5. Trees are nature's epidemic prevention workers.

Many trees secrete fungicides to kill bacteria. For example, one hectare of juniper fruit secretes 30 kilograms of fungicide every day, which can kill diphtheria, tuberculosis, typhoid, dysentery and other germs. It has been reported that the number of bacteria in the air in downtown towns is more than 7-3 times higher than in green areas.

Places with woods contain more than 85% less bacteria per cubic meter of air than busy streets.

The wind is cool (it is cool under the big tree);

release of oxygen (relying on photosynthesis, releasing oxygen);

precipitation level (through transpiration, lowering the water table);

Blocking strong winds (there are trees to block strong winds, which can play a protective role);

vertical markers (big trees on the edge of Taihu Lake, as well as the role of setting up navigation beacons for fishermen);

Add scenery (there are mountains, water, and trees, in order to form a beautiful landscape);

Offering wood (if necessary, you can provide wood for everyone, which is a kind of use for killing chickens and eggs).

The roots of the tree will stabilize the soil and prevent soil erosion.

Manufacture of chopsticks, matches, paper, furniture. Some houses are also made of trees and are called wooden houses.

When the tree has withered, it can be cut down to make a fire.

Absolutely original, think for yourself.
