In the movie “me and my hometown”, one of the most impressive unit stories for the audience is called “the way back home”. The plot expresses the world’s respect for the Maowusu Sand Control people. Since the 1950s, a number of sand control people have paved their way back to their hometown with their hard work, making Huangsha completely green. The biggest problem that has been puzzling all over the world is the problem of desert. The climate of desert is changing greatly, and the harsh desert environment is a serious threat to human survival and health.

The Maowusu sandy land has experienced a historic transformation of “green sand advance and retreat”
When it comes to deserts, China has the most say, because China has the largest desert area in the world. The whole desert area has reached 710000 square kilometers. What does this figure represent? 710000 square kilometers, equivalent to two German cities. In this 710000 square kilometers, there are 12 deserts, some of which are Sandy. Some netizens can’t help asking, “isn’t sand a desert?” Although “sand” is also called “desert” in our name, there is a big difference between desert and sand in the scientific community. Only the quicksand in the completely arid area is called desert, while the quicksand in the semi-arid area is called sand.
The 12 deserts are divided into eight deserts and four deserts. The eight deserts are Taklimakan Desert, Qaidam desert, Gurbantonggut desert, Kumtag Desert, Badain Jaran Desert, Ulanbuh Desert, Tengger Desert and Kubuqi Desert. The four sandy lands are Mu Us sandy land, Hunshandake sandy land, Horqin sandy land and Hulunbeier sandy land. It is worth mentioning that now China’s four major sandy land has become three major sandy land, among which
Mu Us sandy land became “Mu Us forest”.

Mu Us sandy land is one of the four largest sandy lands in China, which is located between Yulin area of Shaanxi Province and Ordos City of Inner Mongolia Autonomous Region. Compared with other deserts, Maowusu sandy land is not a pure natural desert. As early as the Wei, Jin, southern and Northern Dynasties, it was a vast grassland, where the Huns lived for a long time. In the Tang Dynasty, Maowusu eventually became a small piece of sand due to the herdsmen’s wanton reclamation of grassland and the constant wars among different nationalities. Without vegetation coverage, Mu Us area is like an “infectious disease”, the sand area is expanding, and the vegetation is less and less, which is ruthlessly engulfed. The ancient people living there only know how to escape and look for the next prairie, but they don’t know how to improve the ecological environment here.
The Mu Us sandy land covers an area of 42200 square kilometers, and the annual precipitation is only 440 mm at most. The wind and sand are rampant, the land is barren, and the ecological environment is extremely fragile. Shaanxi, which is located across the Yangtze River and Yellow River, is suffering from serious soil erosion and desertification. Before that, people have not taken off the label of poverty. The most typical example is Yulin City, which suffered from sandstorm for a long time. In order to improve this bad ecological environment, desertification control has been carried out since 1959. With the unremitting efforts of generations, the barren desert has been completely improved, and the Mu Us sandy land has finally withdrawn from the historical stage of “desert”. It is worth mentioning that for thousands of years, China has once again done something unprecedented, eradicating the Mu Us sandy land and turning the Gobi desert into an oasis! So how did the Chinese do it, and by what means did they realize their dream of transforming the Gobi into an oasis?

1. Huangsha has made people suffer a lot, relying on their perseverance to control desertification and forestation
In the early days of liberation, Yulin formed a passive situation of sand advancing and people retreating, and Mu Us sandy land completely became a pain in Yulin’s heart. Because of the sand all over the land, it is impossible to develop agriculture at all. Yulin people of the older generation clearly remember:
“Eat bran vegetables, wear fur coat all year round, northwest wind blows from morning to night” situation
At that time, people’s life was miserable. The desert is spreading, eroding the living space of people here. In order to prevent the sandstorm from threatening the next generation, Baixin began to control the sandstorm and plant trees one after another. With a firm belief, the people living here are still fighting against the Mu Us Desert,
Sometimes, just after planting a batch of saplings, a strong wind blows, and the saplings will be completely destroyed
Even so, the people still did not give up and insisted on afforestation day after day.

A red heart for more than 40 years
In the process of harnessing the Mu Us Desert, in addition to the outstanding contributions made by ordinary people, there were also the first generation of bulanghe women’s militia, also known as the sand control militia. At that time, they came to the boundless Mu Us desert with a red heart, and this persistence lasted for more than 40 years. With the spirit of “self-reliance and hard struggle”, these female militia fought against the harsh sandstorm in the Maowusu Desert. When the winter goes and the spring comes, these female militiamen dedicate all their beautiful youth here. They are pale and gaunt, and all their blood is to weave an oasis dream without regrets. It is precisely this belief that this female militia company, with the great attention and strong support of the state, has managed the Mu Us Desert better and better. The change of the Mu Us Desert cannot be separated from their efforts.

3. “Three North Shelterbelt Project” starts to build Gobi oasis in a new era
He sold the only valuable sheep in his family to buy saplings; he would rather work hard than earn money, as long as she could exchange saplings; a little girl who has no strength to bind a chicken with her hands would also go to the Gobi desert to plant trees with her shoulders and hands digging against the strong wind and bad sand It is this group after group of hardworking and simple people who want to plant trees in their lifetime. The country is finally determined to support the desertification control project to the end. In the late 1970s, the “Three North Shelterbelt Project” was completely launched. Science and technology made farmers living here understand that the reason why they had been unsuccessful in planting seedlings before was that there was no sand fixation. In the desolate desert, the sand control heroes repeat their boring work day after day. It is with their perseverance that the shrubs can take root and thrive here, making maowusudi a lush oasis!

4. The energy of “ant forest” has changed the desert
It is worth mentioning that the transformation of Mu Us sandy land into oasis is partly due to the function of “ant forest”. After Ma Yun created the e-commerce platform, it facilitated the daily life of the people. Unremittingly, Ma Yun created many charitable works, such as the ant forest, the most common cause of Alipay. It is like a game. If we plant seedlings in ants’ forests, Alipay will grow a real tree in desert areas and the desert area will gradually decrease after the seedlings grow. Forests have undergone tremendous changes, and trees have been planted in many desert areas. It can be seen that MU US has changed from sand to oasis, and the role of ant forest can not be underestimated.

The world desert tree planting which strong, Asian China when self-improvement!
Nowadays, China has proved the miracle of transforming Gobi into oasis to the whole world with high-tech means. For the Chinese people, no piece of land is useless. Generations of people can persevere in doing a simple big thing. Maybe only the Chinese people can do it, because we always believe that it is reasonable for Yugong to move mountains. We can plant hundreds of millions of acres of forests by changing sand into soil. What makes countries all over the world curious is, what methods did China use to plant trees in the desert, and why is it so strong?
Grass square sand barrier
In many people’s minds, the process of desertification control is very simple, that is, afforestation in the desert. The implementation of desertification control is not as simple as we think, because the desert environment is harsh, the climate is changeable, not only the long-term water shortage and drought, but also the soil conditions are very harsh, so simple afforestation, even when planted at that time, when the wind is raging, these planted seedlings will be destroyed Therefore, according to this harsh desert climate, Chinese researchers have developed a better way to control desertification, namely grass square grid sand barrier. The grass grid is very simple in the process of implementation. The staff need to lay straw and wheat straw in the shape of a grid on the sand dune, and then bury their roots with sand, and sprinkle all the grass seeds in the middle of the grid, even if the layout is completed. This way can well control the spread of the desert area, intercept water, improve the water content of the sand layer, and increase the water content of the sand layer to the maximum extent The speed of desert management has been increased.

The most fundamental reason for soil desertification is the loss of universal binding constraints. For example, this kind of relationship is like gravity, which allows people to “fly” but move freely. If you want to turn sand into soil, you need to give it a new “binding force.”. Yi Zhijian, a professor of Chongqing Jiaotong University, led the scientific research team to open up the mystery. He extracted a kind of plant fiber adhesive from plants. As long as the adhesive is put into the sand and added with an appropriate amount of water, the sand can become a soil with “universal binding constraints”. This kind of desertification soil technology, now has made a breakthrough success. This technology is coveted by many countries. Before that, the UAE signed an agreement with China to turn 100000 square kilometers of desert into fertile land within three years.
Minimally invasive drilling and tree planting
The traditional method of planting trees is to dig a tree pit on the ground, and then plant the seedlings. But in fact, this method is very easy to damage the soil ecology, and the efficiency is very low. In the process of sand control, Chinese researchers have developed a new tree planting method called “minimally invasive drilling tree planting method”. That is to use normal pressure water as the power to punch a hole about 1 meter deep in the sand with a rubber hose, and then insert the seedlings into the hole, so that the seedlings can be closely combined with the sand layer. The whole process only needs three steps: digging, planting and watering, which can be completed at one time.

To sum up, China is the country with the most deserts in the world, but at the same time, it is also the country with the best sand control projects in the world. It has to be said that from the last century to the present, behind the transformation of the Maowusu Desert into an oasis in China, the wisdom and hard work of generations of sand control people have also been gathered. It is believed that in the near future, China will depict its advanced sand control technology as a picture of the Gobi Desert turning into an oasis that will amaze all countries in the world.
