What are the benefits of planting trees on Arbor Day?

Afforestation can preserve water and soil. Where the vegetation coverage rate is low, a large amount of sediment will flow into the river during the rainy season. Here is what I have compiled for you. What are the benefits of planting trees on Arbor Day? , you can collect and share if you like!

What are the benefits of planting trees on Arbor Day?

1. Maintain water and soil

Plant trees Afforestation can control desertified farmland, control soil erosion, prevent wind and fix sand, and increase soil water storage capacity.

And as the economic forest gradually enters the mature stage, the direct and indirect economic benefits generated are huge, and it can also provide a large number of labor and employment opportunities and promote the sustainable development of the local economy.

2. Resist wind and sand

Planting trees can prevent wind and sand. Wherever the sand blows, pastoral areas will be buried and cities will turn into ruins. To resist the attack of wind and sand, protective forests must be built to weaken the force of the wind.

Once the wind encounters the protective forest, its speed will weaken by 70 to 80 degrees. If many forest belts are arranged in parallel at a certain distance and planted with grass, the amount of sand and gravel blown by the wind will be reduced.

3. Economic construction

Afforestation can provide many useful things to mankind. Many fruits and medicinal materials are forest products; tea, rubber, new carbon, etc. are all contributions from trees. The use of woods is really great.

4. Remove air pollution

According to statistics, one acre of forest can absorb 20,000 to 60,000 kilograms of dust a year, absorb 67 kilograms of carbon dioxide and release 48 kilograms of oxygen every day; It can absorb 4 kilograms of toxic gas sulfur dioxide in one month, and one acre of pine and forest trees can secrete 2 kilograms of fungicides in two days and nights, which can kill tuberculosis, typhoid, diphtheria, dysentery and other germs.

5. Automatic thermostat

In summer, the temperature under the shade of trees is about 10℃ lower than in the open space, and in winter it is 2-3℃ higher.

The significance of afforestation

March 12th is Arbor Day in our country. However, if you reverse the number 12, it is Arbor Day in some foreign countries.

March 21st is World Forestry Day. This festival was initiated by Spain at the 1971 Tenerife Conference of the European Agricultural Union and was unanimously adopted by the conference. In November of the same year, it was officially recognized by the Food and Agriculture Organization of the United Nations, so many countries designated this day as their national Arbor Day or Tree Planting Day.

Some foreign scholars have calculated the ecological value of trees: a 50-year-old tree has a cumulative created value of approximately US$196,000. Regardless of whether this calculation is accurate, the practical value of trees is obvious.

A tree can produce 200 kilograms of pulp, and if this pulp is to be produced into toilet paper, it will require at least 750 rolls of toilet paper weighing 100 grams.

In a city, a tree can store the pollutants emitted by a car traveling 16 kilometers a year. Many trees can absorb harmful gases.

For example, 1 hectare of cedar forest can absorb 60 kilograms of sulfur dioxide per day. Others such as Ailanthus ailanthus, oleander, ginkgo, sycamore, etc. all have the function of absorbing sulfur dioxide. When the urban green area reaches more than 50%, pollutants in the atmosphere can be effectively controlled.

Benefits of planting trees

First of all, afforestation can purify the air. During the growth process of trees, due to photosynthesis, they can absorb a large amount of harmful gases such as carbon dioxide, thus purifying the air. According to scientists, the trees on earth. Grasslands dispose of 20 billion tons of waste gas for humans every year. Sometimes a stomata can suck in 2.5 trillion carbon dioxide molecules in one second, and the number can be imagined.

Secondly, afforestation can prevent wind and sand fixation. The protection forest can be cultivated to resist wind and sand attacks. The main function of the protection forest is to reduce the force of the wind. When the wind encounters the protection forest, the speed is reduced by 70-80. It is cultivated turf. With lawn covering the ground, even if there is wind, not much sand will be blown up, which reduces the source of sand particles.

From these two points, it can be seen that afforestation plays a very important role in preventing wind and sand fixation.
