Why do we plant trees on Arbor Day?

Arbor Day is a festival that advocates people to protect the environment and green their homes.

1. Planting trees can increase green vegetation, improve air quality, prevent soil erosion, protect ecological environment and improve quality of life. At the same time, planting trees is also a social responsibility and obligation, and everyone should make their own contribution to protecting the earth's homeland. Arbor Day is a festival that advocates people to protect the environment and green their homes.

2. With the acceleration of urbanization and the development of industrialization, the problem of environmental pollution is becoming more and more serious, the green vegetation is gradually decreasing, and the ecological environment is destroyed. In order to improve this situation, improve the quality of life and protect the earth's homeland, afforestation has become an important task. Planting trees can increase green vegetation and improve air quality. Trees absorb carbon dioxide and release oxygen through photosynthesis.

3. It can reduce the pollutant content in the air and reduce the air pollution index. At the same time, trees can also absorb harmful gases and particles, purify the air and improve people's breathing environment. Planting trees can prevent soil erosion and protect the ecological environment. The roots of trees can fix the soil, prevent soil erosion and maintain the fertility and productivity of the land.

Precautions for planting trees are as follows:

1. Soil conditions: It is very important to choose soil suitable for the growth of trees. Dig a tree pit: Dig a tree pit before planting trees. Generally speaking, the pit is 20 cm larger than the diameter of the root, and its shape can be round or square. It is recommended to dig a hole with a shovel. Select a place with thick soil layer for excavation and control the spacing between tree pits.

2. Prevent the seedlings from not getting enough sunshine when they grow up. Choose the right time: it is best to plant trees on cloudy days, when there is no wind or light rain. Avoid planting trees in rainy days. Watering and management: after planting trees, we should insist on watering, and if possible, we can apply some farmyard manure to ensure the survival of seedlings. At the same time, pay attention to protect saplings from people or animals.

3. Safety precautions: observe discipline and obey arrangements; Pay attention to traffic safety along the way and don't run around on the road; Don't wave the tools you carry (such as shovels and hoes) at will to avoid hurting others; Pay attention to the safety of the afforestation site (such as the presence of weeds, snakes and other animals); Don't plant trees under the power grid.
