First, the origin of Arbor Day
In order to stimulate people's feelings of loving forests and afforestation, improve people's understanding of forest functions, promote land greening, achieve the purpose of loving forests and protecting forests, expand forest resources and improve the ecological environment, China has designated March 12 as Arbor Day every year to encourage people of all ethnic groups to actively participate in the team of greening the motherland and improving the environment. Students should also actively participate in tree planting activities and strive for each child to plant a tree by himself every year!
Due to the evolution of the times, the Arbor Day in China has been revised three times.
Sun Yat-sen was also the first person in modern China who strongly advocated afforestation. He personally drafted the political document "Li Shang Hongzhangshu", pointing out that in order to be strong, China must "develop agriculture urgently and attach importance to tree art". After the Revolution of 1911, in the fourth year of the Republic of China (19 15), at the initiative of Dr. Sun Yat-sen, Zhou Ziqi, Minister of Agriculture and Commerce, recommended himself as the president-to-be, and designated Tomb-Sweeping Day as Arbor Day every year to select tree species. After it was approved on July 2 1 day of that year, the whole country was ordered to comply with it as scheduled.
17 (1928) After the Northern Expedition was completed, on April 7, the Kuomintang government ordered the whole country: "The Qingming Arbor Day in the old calendar was changed to the tree planting method to commemorate the death of the Prime Minister." 18 (1929) On February 9th, the Ministry of Agriculture and Mines announced by ministerial order "Tree planting methods in various provinces to commemorate the death of the Prime Minister". Yi Peiji, Minister of Agriculture and Mines of the Executive Yuan of the National Government, actively advocated tree planting according to Dr. Sun Yat-sen's wishes, and submitted it to the Executive Yuan and the people in February of the Republic of China 19 (1930). March 9th to15th was the "Publicity Week of Afforestation Campaign", and a tree planting ceremony was held on the anniversary of Dr. Sun Yat-sen's death on 12. In the northern region, it is early March, and the cold has not disappeared, so it is not suitable for planting trees. It is specially stipulated that tree planting will still be held on March 12, and the greening publicity activities will be extended to Tomb-Sweeping Day this week. And by the Ministry of Land and Resources announced the "provincial, municipal and county afforestation campaign publicity week program" 7, so that all localities can follow suit.
After the founding of People's Republic of China (PRC), in February 1979, at the sixth meeting of the Standing Committee of the Fifth NPC, Luo Yuchuan, director of the General Administration of Forestry, submitted the Forest Law (Trial Draft) for deliberation, and stated that "March 12 was decided as China Arbor Day", which was adopted by the General Assembly. 19811February 13, the Fourth Session of the Fifth National People's Congress discussed and adopted a resolution on launching a nationwide voluntary tree planting campaign. Since then, the nationwide voluntary tree planting campaign has been implemented as a law throughout the country. The following year, the State Council promulgated the "Implementation Measures for Carrying out the National Voluntary Tree Planting Campaign".
Second, the slogan of Arbor Day
1, vigorously plant trees and prohibit deforestation.
2, bid farewell to the hustle and bustle of the city, into the embrace of green.
3. The predecessors planted trees, and the descendants enjoyed the cool, leaving a space for sustainable development for future generations.

On the Arbor Day on March 12, everyone will plant small trees, one tree, two trees and three or four trees. Fertilization will be applied after planting, and small trees will become big trees. Everyone can do it, and greening the earth depends on everyone.
If you plant a tree today, it will realize one of your wishes two years later. What did you press? Can you plant trees with one thumb?
9. Love forests for afforestation, promote land greening and protect the ecological environment on which human beings depend. Happy Arbor Day!

23. Water is the source of life, and trees are the guardians of water.
24. Afforestation benefits today and benefits the future.
25. Make the earth younger.
Third, the specific steps of planting trees
1, dig a hole. Dig a suitable tree pit according to the length and width of the root system. The depth is generally 50 cm. When digging a pit, the ripe soil on the surface and the loess below will fall on both sides of the pit.
2. Backfill. Before planting trees, some ripe soil should be backfilled in the pit according to the length and width of the roots and the length of the top of the roots. Generally, 20 to 30 cm of ripe soil will be backfilled.
Step 3 plant. Remember the word "321"-three buries, two steps and one lift. When planting saplings, it is necessary to straighten the roots and spread the branches, which is the premise. When planting trees, fill the soil in three times. Fill a little for the first time, stop filling at a certain distance from the top of the pit, walk around the tree on the filled soil, step on it evenly, then gently lift the stem and shake it loose to ensure the roots breathe smoothly. After filling the soil for the second time, walk around the tree again. After the third filling, try to ensure that it is flush with the pit surface. The roots should be aligned with the trees in the north-south, east-west direction. Then, put a large disk around the pit surface to facilitate water conservation in the future.
4. Cover the soil to keep moisture. After planting the saplings, cover them with a thin layer of soil to keep moisture.
Fourth, the benefits of planting trees.
1. Trees can regulate climate and keep ecological balance. Through photosynthesis, trees inhale carbon dioxide and exhale oxygen, making 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, keep water and soil, and absorb all kinds of dust. An acre of forest can absorb 20-60 tons of dust a year.
3. Woods can reduce noise pollution. A 40-meter-wide forest belt can reduce noise10-15db. Noise pollution has caused great harm to human life, study, work and rest, and can be said to be people's "enemy". Therefore, we should pay more attention to afforestation. Noise can also lead to hearing loss, deafness and stupidity, as well as heart, blood pressure and nerve abnormalities in long-term life. Even, it can make people die under long-term noise. In this way, the forest can reduce the noise by four or five times.
The secretion of trees can kill bacteria. There are 34,000 bacteria per cubic meter of air in the open space, and only 300-400 bacteria in the forest. Planting trees is the obligation of every citizen, and the state has designated March 12 as Arbor Day. Planting trees is of great benefit to our study, work and life.
5. Trees can lower the temperature and increase the humidity. At 30 degrees, the temperature can be reduced to about 20 degrees.
The unreasonable exploitation and utilization of natural resources by human beings is the main reason for ecological imbalance. Deforestation, deforestation, overgrazing, etc. It will destroy forests and grasslands, cause soil erosion and land desertification, and make sandstorms occur frequently. Unreasonable development and occupation of land make the cultivated land area decrease day by day. Now that we know so many benefits of afforestation, we should consciously fulfill the obligation of afforestation and lay the foundation for creating our beautiful home. Afforestation not only has very important environmental benefits for human survival, but also has great economic benefits for human production and life.
Verb (abbreviation for verb) Poetry of Arbor Day
Arbor day
Plant a tree seedling,
In that beautiful scenery.
The longer, the higher, the bigger,
I hope the longer the better.
That Sunday,
Go to see the tree quickly.
Tears kept flowing,
The young tree was broken.
I'm gonna bury it,
But always so sad.
I touched it gently,
It's my friend.
