Trees are the earth’s air purification system. Planting trees not only replenishes green plants, but also protects our home.
1. Benefits of tree planting
1. Conservation of water and soil
Afforestation, returning farmland to forest and ecological reconstruction are extremely important. Afforestation can preserve water and soil. Wherever the vegetation coverage is low, a large amount of sediment flows into the river during the rainy season, destroying the fields, filling up the river bed, and blocking the entrance to the sea, which is extremely harmful. To curb soil erosion, we must plant trees, because trees have root systems as huge as tree crowns that can hold onto the soil like giant hands. The captured soil moisture is continuously absorbed and stored by tree roots.
According to statistics, one acre of forest can store about 20 tons more water than an area without forest. Afforestation can greatly improve the ecological environment and reduce losses caused by floods by controlling soil erosion, preventing wind and sand fixation, and increasing soil water storage capacity. As economic forests gradually enter the mature stage, they will generate direct and indirect economic benefits. It is huge and 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
Afforestation 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 be reduced by 70% to 80%. 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. Natural dust collector
There are many fine hairs and mucus on the leaves, which can absorb harmful particles such as carbon and sulfide in smoke, as well as harmful bacteria, viruses and other harmful particles. Substances can also significantly reduce and reduce dust in the air. One hectare of lawn can absorb more than 30 tons of smoke and dust every year. Therefore, people call green plants "natural dust collectors".
2. The significance of tree planting
Trees are the lungs of the earth. I hope everyone can protect forests and trees, and add a touch of green to urban life! Protecting trees means protecting the earth. It is to protect us humans! For all of us, the meaning of tree planting is not just as simple as planting a tree. The significance of Arbor Day to us is not only to plant more trees, but also to cultivate the concept of caring for nature and living a low-carbon life among our citizens. Data expansion:
Afforestation is a production activity that creates or renews forests. It is a basic link in cultivating forests. Planting trees is beneficial to future generations. The ancestors left thick shade trees so that the children and grandchildren of future generations can enjoy the shade. Planting areas that are large and can form forests and forest environments in the future are called afforestation. If the area is small and cannot form a forest and forest environment in the future, it is called tree planting. The basic measures for afforestation are: suitable trees for the right site, careful land preparation, improved seeds and strong seedlings, appropriate dense planting, tending and protection, tool modification, and possible irrigation and fertilization.
