Five Benefits of Afforestation

1, resist sandstorm. Afforestation can prevent wind and fix sand. Once the wind meets the shelter forest, the speed will be reduced by 70% ~80%. If many forest belts are arranged in parallel at a certain distance and grass is planted, the sand blown by wind energy will be reduced.

2. Maintain soil and water. Afforestation can control soil erosion, prevent wind and fix sand, increase soil water storage capacity, greatly improve ecological environment and reduce flood losses.

3. Adjust the temperature. In summer, the temperature in the shade is 5- 10℃ lower than that in the open air, and it is 2-3℃ higher in winter.

4. Control air pollution. Afforestation can eliminate air pollution. According to statistics, an acre of forest can absorb 20,000-60,000 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 a month, and one acre of pine and cypress can secrete 2 kilograms of bactericide for two days and nights, which can kill bacteria such as tuberculosis, typhoid fever, diphtheria and dysentery.

5. Absorb carbon dioxide, make oxygen, and keep the air composition relatively stable. Leaves can absorb carbon dioxide from sunlight and make oxygen needed by human body. It is measured that one hectare of broad-leaved forest absorbs about one ton of carbon dioxide and releases 700 kilograms of oxygen every day. Therefore, people call green plants "oxygen factories".

Precautions for planting trees:

1. Wear dirty and wear-resistant clothes and sneakers, and put on gloves.

2. Bring your own drinking water.

3. Plant trees in the wild according to the organizer's arrangement, and pay attention to your own safety.

4. Lay gravel or sand on the bottom of the tree pit to provide drainage.

5. Adding proper amount of fertilizer and organic matter is beneficial to plant growth.

6. After planting trees, water them and keep them moist.

7, regular pruning and cleaning, to ensure that trees have a good growth environment.
