The earth is turning into a big ball of sand, believe it or not? Desertification plagues 40% of the world's land, and the situation in China is even more worrying.
The Eight Great Deserts and the Four Great Sandy Lands are like scars on the skin of the earth, stubborn and incurable.
Why haven't we been buried in the sand, you may ask? That's a long story.
In the early years, what did we rely on to control desertification? Rely on crowd tactics.
Thousands of desertification control workers braved the scorching sun to plant trees in the desert one by one.
There is nothing wrong with having more people, but it is inefficient and frighteningly expensive.
Planting a tree takes more time and money than raising a child.
What's even more troubling is that the survival rate of these saplings is pitifully low in the harsh environment.
Later, we had the "grass grid sand control method".
It sounds lofty, but it's actually time-consuming and labor-intensive.
This method is to weave the grass into squares and then grow plants in it.
Although it is effective to a certain extent, it is still inefficient, the cost remains high, and the survival rate is not high.
You say, if this continues, when will the desert be green?
In 2016, the team of Professor Liu Junhao of Beijing Forestry University developed a magical machine - a multi-functional sand fixing machine, which is known as the "sand swallowing monster" by the people of the rivers and lakes.
This is a big guy, integrating sowing, irrigation, and fertilization, and can automatically adjust the working mode according to different desert environments.
It's like a Transformer in the desert, where you need to go.
Compared with the traditional method of planting trees, the efficiency of the "sand swallowing monster" has increased several times.
It can plant 40 acres of land a day, which is more than four times that of artificial labor.
What's more, the survival rate of plants is as high as 80%, which is much higher than before.
The machine can also automatically adjust various parameters according to real-time land conditions to achieve precise sand control.
In recent years, Professor Liu Junhao's team has also upgraded the equipment of the "Sand Swallowing Behemoth" and added an adaptive oscillating disc to make it move more flexibly in the desert.
You may think that these data are a bit abstract, let's take Gansu as an example.
Every year, the "sand swallowing monster" can control more than 2 million acres of desert in Gansu.
Who can't be thrilled to see these oases gradually expanding?
When it comes to the advantages of the "Sand Swallowing Behemoth", it is impossible to talk about it for three days and three nights.
First of all, it's a multi-functional integrated guy that can adapt to different desert environments.
Whatever you want to plant, it can do it.
Secondly, it is equipped with advanced sensors and control systems that can monitor soil data in real time and automatically adjust parameters.
Don't look at it big, but it's very delicate.
The most important thing is that it can work 24 hours a day, and the efficiency is uninterrupted.
With the help of advanced technologies such as the "sand swallowing monster", China has made remarkable achievements in desertification control.
The area of desertification and desertification continues to decrease, which is the result of the joint efforts of everyone.
However, desertification control is a long and arduous task that requires our persistent efforts.
In the future, we also need to continuously upgrade the technology of the "sand swallowing monster" to make it smarter and more efficient.
The "sand swallowing monster" not only shines in China, but also goes abroad and becomes a popular choice for global greening.
Many countries have learned from China's experience, and even directly purchased "sand swallowing monsters" for their own desertification control.
You think our machine is amazing, right? It is not only powerful, but also very practical, solving the common problem of desertification in the world.
Desertification is a common challenge for all mankind and requires us to work together to address it.
In the future, China will continue to adhere to the development concept of "lucid waters and lush mountains are invaluable assets", and make more contributions to building a beautiful China and a beautiful world.
Hopefully, in the near future, we will be able to defeat desertification and return green to the earth.
