Pulling the huge clouds in the sky, Lin Han once again passed through the tunnel that crossed the Sino-Mongolian border, returned to northern Shaanxi, and then came to the Mu Us Desert in Yulin, where he slowly split the huge clouds and evenly distributed them over the vast desert of nearly 15,000 square kilometers.

In the morning of the same day, when the clouds were surging in the sky, he sent a notice to the Weather Modification Office to prepare for the implementation of artificial rainfall.

With the experience of the last time, the weather modification office immediately dispatched several teams to the predetermined location to carry out rain enhancement with all the equipment for launching rain enhancement bombs.

With the launch of rain-enhancing rockets, thick smoke rose from many parts of the Mu Us Desert and soared into the sky......

"Wow-"

It didn't take long for a trickle of rain to fall in the sky.

The rain spread rapidly, from the initial breeze and drizzle, and soon had a bit of momentum.

The Mu Us Desert is only 15,000 square kilometers in Yulin, but the cloud qi collected by Lin Han this time almost condenses all the cloud water vapor in half of South Gobi Province, which is at least five times the size of this desert in terms of area.

Therefore, although the climate of South Gobi Province is not humid, the rain that falls on the Yulin Desert is also very considerable.

"Whoa...... Whoop ......"

The rain poured in the cold wind, and as soon as the rain fell into the yellow sand, it dissolved the desert binder powder that covered it.

The rainwater mixes with the desert binder, and then it turns into a grayish-brown liquid that flows, permeates and blends between the yellow sands......

Compared with gravel, there is a binding force between soil particles, which can be combined into a clump, which is a rheological state when wet and a solid state when dry, and the two states can be transformed steadily between each other.

However, sand is discrete from each other, and without this constraint, it cannot support plants, buffer and stabilize environmental changes, and cannot conserve water and soil and prevent nutrient loss.

After being modified with a desert binder, a "modified sodium carboxymethyl fiber", the sand quickly acquires a confinement similar to that of the interior of the soil, that is, it has the physical properties of the soil.

So after a rain baptism, these long yellow sand soon showed a viscous and condensed trend, from a plate of loose sand to a mud-like form.

After the rain, the Mu Us Desert in Yulin has turned into a vast mud land of 15,000 square kilometers.

When it dries a little, the sand and mud that has been "turned into soil" looks similar to the untreated loess, but the color is a little different.

Compared with the endless scene of the long yellow sand not long ago, although it is also desolate, it can already be said to be quite amazing.

Turn sand into dirt!

The 15,000-square-kilometer Yulin Desert has turned into a vast land in such a short period of time.

The shock brought by this change really feels a bit "earth-shaking".

The "Shaanxi Reform Commission" has also begun to coordinate with local governments and enterprises to issue commissions. Sanitation companies and garbage disposal companies in several nearby cities in northern Shaanxi and Inner Mongolia have been busy, transporting a large amount of organic waste from all over the country.

After all, biological properties are more important to soil than physical properties.

Without microorganisms, organic matter, and other necessary conditions for plant growth, the soil and desert are not much different.

While the "Shaanxi Reform Commission" and various sanitation companies are busy, it is natural that the progress of the management of the Yulin Desert has once again entered the attention of countless media, attracting worldwide attention.

Originally, desert adhesives were only used in small quantities in the deserts on the edge of large cities due to many restrictions, and were not promoted.

But after the Mu Us Desert, almost everyone focused on the "desert adhesive" developed by Professor Yu, and the Internet and media were even more lively.

The sudden fanatical pursuit made Professor Yu Jian a little flattered.

After all, he knew that without an adequate water supply, the significance of desert binders was very limited, and he could not afford such a big reputation.

But the media didn't care about this, and only blew it vigorously, as if they would not give up if they did not say that Professor Yu Jian was a contemporary Einstein.

For example, today, when some members of the "Shaanxi Reform Commission" were inspecting the Mu Us Desert, a large wave of media came to hear the news and were busy conducting various interviews.

Professor Yu is naturally the center of media focus, and he has to deal with a few words in the face of inquiries from the media in front of him.

"Professor Yu, how did the Shaanxi Reform Commission contact you and use the desert adhesive CMC as the core of a desert restoration?" asked a reporter holding a microphone.

Professor Yu said very frankly: "Not long ago, Director Lin told me that the Shaanxi Reform Commission hopes to use desert adhesive to repair the Mu Us Desert and turn sand into soil ......."

"At that time, I didn't know much about this, and in the spirit of seeking truth from facts, I said to Director Lin, I said that you should ask for another master, CMC is not as amazing as you think. ”

The click-click photo sound came and went, and the reporter interjected and asked: "You are too modest, why do you say that?"

Professor Yu Jian waved his hand: "I'm really not modest, the desert adhesive has a hard water requirement. As we all know, the root cause of the desert problem is the lack of water. ”

"If it weren't for the rain from Vientiane Lab and the Weather Modification Office in Yulim, CMC wouldn't have played such a big role, and I just did a small job. He said slowly, in a very calm tone.

The reporter followed up and asked: "Then may I ask, how does the "Shaanxi Reform Commission" achieve efficient rainfall in northern Shaanxi?"

Professor Yu lifted down his black-framed glasses: "This, I'm sorry, I can only say that I have no comment." ”

"Professor Yu, may I ask ......?"

"Professor Yu ......"

Professor Yu Jian attracted the firepower of reporters and media, and other investigators of the "Shaanxi Reform Commission" were able to carry out the investigation work relatively smoothly.

The committee still attached great importance to this activity, and even Zhang Shihou, who had just finished his work in the provincial party committee, also came over at this time and followed everyone to inspect the Mu Us Desert.

Zhang Shihou leaned over and pressed the ground, and couldn't help but say: "This desert adhesive has a really magical effect. In the blink of an eye, the desert became almost like the yellow earth. ”

Lin Han nodded: "Yes, as long as the second restoration is carried out to replenish the soil organic matter content, the desert problem of Yulin will be completely solved." ”

Zhang Shihou stood up and clapped his hands: "By the way, didn't you say before that increasing rain is not a long-term solution, and controlling the Yellow River is fundamental." ”

"Do you have any thoughts on the management of the Yellow River now?"
