Why plant trees? Why plant trees?

1. Maintain soil and water.

Afforestation, returning farmland to forest, and ecological reconstruction are extremely important. Afforestation can conserve water and soil, **vegetation coverage is low, **every rainy season, there will be a large amount of sediment into the river, destroying the fields, filling up the riverbed, silting up the estuary, and causing great harm.

To curb soil erosion, it is necessary to plant trees because trees resemble tree canopies.

With such a huge root system, it can grasp the soil like a giant hand. The water of the soil that is caught is constantly absorbed and stored by the tree roots.

2. Automatic thermostat.

In the shade of the trees, the temperature is about 10 times lower than in the open field in the summer, and 2-3 times higher in the winter.

3. Natural dust collector.

There are many small hairs and slime on the leaves, which can absorb carbon and sulfide in soot.

and other harmful particles, as well as harmful substances such as germs and viruses, can also greatly reduce and reduce the dust in the air, and one hectare of lawn can absorb more than 30 tons of soot per year. Therefore, people refer to green plants as "natural dust collectors".

4. Oxygen manufacturing plant.

Leaves absorb carbon dioxide in sunlight.

and make the oxygen that the human body needs. It has been determined that one hectare of broad-leaved forest absorbs about one tonne of carbon dioxide and releases 700 kg of oxygen per day. For this reason, people refer to greenery as "oxygen plants".

5. Disinfection station for bacteria.

Pine, camphor, elm and other trees can secrete fungicide to kill Mycobacterium tuberculosis.

Diphtheria bacillus and other germs.

Reasons why you should plant trees:

1. Trees can regulate the climate and maintain ecological balance.

Trees through photosynthesis.

Inhale carbon dioxide.

Spit out oxygen to make 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, 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 decibels. Noise pollution has caused great harm to human life, study, work, rest, etc., and can be said to be people's "surplus enemy". Therefore, we should pay more attention to afforestation.

Noise can also make humans hearing weakened and deaf in long-term life.

Becoming stupid, abnormalities in the heart, blood pressure, nerves, etc. It can even make people die under the torment of long-term noise erection. This way the woods will reduce the noise by four.

Five times. 4. The secretions of trees can kill bacteria. There are 34,000 bacteria per cubic metre 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.

The reasons for planting trees are as follows:

1. Protect the ecology

Tree planting is a very important factor in protecting the ecological environment, not only to control soil erosion, regulate the climate, but also to provide a good environment for animals to grow.

2. Beautify the environment

Planting trees can also beautify the environment, it is precisely because of the existence of trees that our homes are so beautiful, if the number of trees decreases, the surrounding is full of high-rise buildings, which will make the living environment lack vitality and have no beauty.

3. Resist wind and sand

Afforestation can prevent wind and sand fixation, where the wind and sand go, the countryside will be buried, the city will become ruins, to resist the attack of wind and sand, we must plant trees, weaken the power of the wind, block the wind and sand, and provide a good living environment for human beings.

China has had a tradition of planting trees since ancient times, and many interesting stories about Zheng Feng's advocating afforestation have emerged. The best time to plant trees is the Qingming season, when the climate is warm and the spring rain is sprinkled, which is conducive to the survival of saplings. Afforestation is of great significance for regulating climate, conserving water and reducing air pollution.

March 12 is the official Arbor Day in China. The nationwide voluntary tree-planting campaign has given a strong impetus to the improvement of China's ecological situation.

In 1981, before the campaign began, China had a forest area of 100 million mu, a standing tree stock of 100 million cubic meters, and a forest coverage rate of 12%. After years of unremitting struggle, China's forest area has reached 100 million mu, the volume of standing trees has reached 100 million cubic meters, and the forest coverage rate has increased to.

Afforestation can not only green and beautify homes, but also play a role in expanding mountain forest resources, preventing soil erosion, protecting farmland, regulating climate, and promoting economic development.

The purpose of Arbor Day is to stimulate people's feelings of love and afforestation, improve people's understanding of the function of forests, promote land greening, and achieve the purpose of loving forests and protecting forests, expanding forest resources and improving the ecological environment.

Steps to plant a tree.

1. Dig a pit. Dig a tree pit of appropriate size according to the length and width of the root system. The depth is generally 50 cm. When digging a pit, the cooked soil on the surface and the loess below should be poured on both sides of the pit.

2. Backfill. Before planting trees, according to the length and width of the roots and the length of the top of the root system, part of the cooked soil should be backfilled in the pit. In general, backfill cooked soil 20 to 30 cm.

3. Planting. Remember the phrase "three-two-one" - three buried, two stepped on the leak, one lightly mentioned. When placing the sapling, the roots should be straightened and the branches should be aligned, which is the premise. When planting trees, the soil should be filled in three times.

4. Covering soil and preserving moisture. Once the saplings are planted, cover them with a thin layer of soil to retain moisture.

Here are the benefits of tree planting:

1.Planting trees removes complete pollution.

According to statistics, one acre of forest can absorb 26,000 kilograms of dust a year, absorb 67 kilograms of carbon dioxide per day, and release 48 kilograms of oxygen; It can absorb 4 kg of toxic gas sulfur dioxide in a month, and one acre of pine and cypress can secrete 2 kg of fungicide for two days and nights, which can kill tuberculosis, typhoid, diphtheria, dysentery and other germs.

2.Planting trees can reduce noise and beautify the environment.

It can reduce noise, beautify the environment, maintain ecological balance, and provide an ideal place for human beings to study, work, play and live.

3.Planting trees balances the earth's carbon dioxide.

Forests are the main consumers of carbon dioxide, and every 10 tonnes of dry matter produced per hectare of forest absorbs 16 tonnes of CO2 and releases 12 tonnes of oxygen, making forests a huge reservoir of oxygen. Therefore, afforestation has become the main way to mitigate the greenhouse effect.

4.Planting trees can prevent wind and fix sand.

Forests can reduce the intensity of wind erosion by reducing wind speed and changing wind direction; The strong root system of forest trees, especially shrub trees, can hold soil particles in place. Practice has proved that by creating windbreak sand forests and cooperating with agricultural and water conservancy measures, good windbreak and sand fixation effects can be achieved.

Trees can take shade.

Tree roots can grasp and grasp the soil.

Trees can teleport wind.

Trees can neutralize yin and yang.

Arbor Day is to protect and advocate the people to plant trees, encourage people to care for trees, and remind people to pay attention to trees. Trees play a very important role in the survival of human beings and the ecological environment of the earth.

Afforestation can not only green and beautify the homeland, but also play a role in expanding mountain forest resources, preventing soil erosion, protecting farmland, regulating climate, and promoting economic development. In order to protect forestry resources, beautify the environment and maintain ecological balance, many countries in the world have set up Arbor Day according to their actual conditions.

The fundamental purpose of China's Arbor Day is to protect forests and plant more trees. The growth of each big tree has a considerable positive effect on human society.

Tree planting is an extremely important environmental protection work. With the continuous development of human activities, environmental problems are becoming more and more serious, including climate change, land degradation, water scarcity and other problems. As an environmental protection measure, tree planting can alleviate the above problems and protect the ecological environment.

This article will elaborate on why tree planting is needed from several aspects.

1. Maintain ecological balance.

Planting trees can help maintain the ecological balance. At the heart of ecological balance is species diversity and ecosystem stability, and tree planting can provide a variety of habitats and breeding environments. In addition, tree planting can also maintain the interaction between plants and animals, maintaining a balanced relationship between species in the ecosystem.

Through tree planting, afforestation, greening and other work, the relationship between plants and animals can be improved, and the natural ecological environment can be protected.

2. Prevention and control of natural disasters.

Planting trees can help prevent natural disasters. Trees have the role of soil fixation and windbreak and sand fixation, which can avoid land degradation and desertification, and protect forest and land water sources. Even in natural disasters such as storms and floods, trees that are dense enough can still act as a ward off severe storms and mitigate waterlogging.

In addition, large areas of ecosystems such as rainforests can regulate temperatures and reduce the occurrence of natural disasters.

3. Improving the climate.

Planting trees can also help improve the climate. While photosynthesizing, trees release a large amount of oxygen, which can purify the air and alleviate the problem of air pollution. In cities, planting trees can not only create green belts and reduce dust particles in the air, but also help reduce urban heat, increase water quality, and improve the urban ecological environment.

Fourth, a prosperous economy.

Planting trees can even lead to economic development. Afforestation is clearly a long-term investment project that requires sustained investment. In this process, agricultural and forest products are produced that can contribute to the development of the local economy.
