What is the role of a big tree, what is the role of a big tree

Trees can provide oxygen for human beings, purify the air, beautify the environment, and contribute to the protection of the ecological environment. Trees have photosynthesis, and trees release oxygen under photosynthesis, like "green factories". When we inhale oxygen and then exhale carbon dioxide, the trees will suck in the oxygen we exhale, and then release fresh oxygen for us to grow healthy and happy!

According to statistics, one acre of forest can absorb 67 kilograms of carbon dioxide and release 49 kilograms of oxygen every day, which is enough for 65 adults to breathe. Because the forest has the role of shading and sheltering from the wind, tree respiration and transpiration, the place with a forest is warm in winter and cool in summer, which can be used to recuperate from the heat, which is the first choice for us to rest and vacation. Trees also have the effect of sticking to dust in the air, making the air clean and fresh.

Scientific tests have shown that one acre of forest can absorb 4 kg of toxic gas sulfur dioxide in a month, and 20 tons and 60 tons of dust in a year. In addition, in the process of respiration, trees produce a large amount of special air, which can lead to some diseases and have a good effect on the human body, such as birch, poplar, cypress, etc., which can secrete plant heteromycins, which can kill diphtheria, tuberculosis, typhoid, dysentery and other pathogenic bacteria.

Trees can also reduce the noise emitted in the industrial area, and planting a variety of tree types, flowers and fruits and verdant foliage on both sides of the road can not only beautify the environment, but also provide an ideal environment for people to study, work and live. Afforestation is also very important for human life, and our desks, bookcases, paper, etc., are all made of wood, which brings great help to our life and study. It also prevents soil erosion.

In Shanxi, Shaanxi and border Xinjiang, soil erosion is extremely serious!

Regulates the climate: The branches and leaves of large trees are in photosynthesis.

Can purify the air while transpiration.

It can increase the humidity of the air.

Noise reduction: Leaves and bark absorb echoes. Sterilization: Secretions from large trees can destroy bacteria. Wind and sand fixation: The large tree is tall and has a barrier effect. Industrial value: can make furniture.

1. Regulate the climate

The branches and foliage of large trees are luxuriant, and as they grow, the leaves will photosynthesize and absorb carbon dioxide from the outside world.

Oxygen is released to keep the environment fresh, and the transpiration of the leaves releases moisture, increasing the humidity of the air and thus reducing the temperature.

2. Reduce noise

The bark of large trees is coarse, which can absorb echoes, and the lush leaves are very absorbent of external sounds, so large trees can reduce noise, and generally a 10-meter-wide forest can reduce noise by 30%.

3. Sterilization

The substances secreted during the growth of large trees have the effect of sterilization and sterilization, which can destroy the bacteria in the air, so there are only more than 300 bacteria per cubic meter of air in the forest, and more than 40,000 bacteria per cubic meter of air in the open space.

4. Wind prevention and sand fixation

The root system of the tree is more developed, and in the process of growth, the root system will extend deep into the soil, so as to protect the soil layer and avoid being washed away by the current, and the tall tree can resist the outside wind and act as a barrier.

5. Industrial value

Large trees have industrial value, and the cut trunks can be used as wood to make furniture or buildings, or as raw materials for wood carving, processed into works of art.

Photosynthesis. Trees photosynthesize with sunlight and absorb carbon dioxide from the air.

Thus oxygen is released. Protective effect: Large trees make cities and villages less affected or even protected from wind and sand disasters.

Universal props: Since ancient times, people have used trees to build houses and make musical instruments. Now we have wooden houses, wooden chairs, wooden benches.

The paper is made of trees. <

1. Photosynthesis: Since trees photosynthesize with sunlight, it can absorb carbon dioxide from the air, thereby releasing oxygen. So. Every time we walked into the woods, a fresh air came to our nostrils.

2. Protective effect: large trees can also make cities and villages less affected or even protected from wind and sand disasters. Many people write figurative sentences.

will write trees like an umbrella. I don't think this is an exaggeration at all. Trees are the umbrella of our planet.

3. Universal props: Since ancient times, people have used trees to build houses, make musical instruments, and so on. Now we still have wooden houses, wooden chairs, wooden benches. Even the paper is made of trees. Therefore, trees are indispensable little helpers in our lives.

The role of the tree is: regulating the climate, windbreak and sand fixation, conserving water and soil, reducing noise pollution, etc., its secretions can also kill bacteria, in addition to the environment, you can also make a variety of tables, chairs and other wood products, more afforestation is very beneficial to human beings.

Large trees can perform transpiration to regulate the humidity of the air.

Large trees can fix the soil and prevent soil erosion, and large trees can also act as a barrier to keep out wind and sand.

The role of big trees: it can maintain ecological balance, because trees can inhale carbon dioxide and exhale oxygen through photosynthesis, so they can make the air fresher and cleaner; Large trees can prevent wind and fix sand, because the roots of trees need to be consolidated, so they can inhale a lot of dust, and can also conserve water and soil; Large trees can also reduce noise pollution, and a 40-meter-wide forest belt can reduce noise by 10-15 decibels; Secretions from large trees can also kill bacteria. Trees and our human survival are closely related and inseparable.

How to protect large trees:

1. Do not cut down trees indiscriminately, because flowers and trees are the green barrier of nature, and some protective measures should be taken, rather than trampled on. For example, indiscriminate cutting and logging will cause a lot of soil erosion and so on.

2. Winter protection measures, in the winter of the blue book wrapped in silver, you can use a rope to surround the trunk of the tree, so that the tree is far away from the attack of cold wind. At the same time, a thick layer is placed around the trunk to keep the trunk warm, so as to avoid cracks in the trunk.

3. Strengthen the trunk support, when the tree does not grow well, the branches droop and tilt, which is easy to be pested, wilted and died. At this time, the trunk is reinforced with iron hoops, wooden poles, mud ropes, cement and other supplies.

4. Don't pick leaves indiscriminately, with the progress of the times, most people are yearning for a green life. However, in order to satisfy their inner desires, many people will choose to swing on the branches. However, this practice can cause serious damage to the tree, such as falling off leaves, breaking branches, and so on.

1.Trees regulate the climate and maintain ecological balance, and through photosynthesis, trees inhale carbon dioxide and exhale oxygen, making the air 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, an acre of forest can absorb 20 60 tons of dust a year. 3.

Forests reduce noise pollution. A 40-metre-wide forest strip reduces noise by 10-15 decibels. Noise 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.Tree secretions 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 reduce temperature and increase humidity. The temperature of 30 degrees can drop to about 20 degrees.
