Chapter 860: Changing the World

For hundreds and thousands of years.

It can even be said that since the emergence of large-scale civilization.

Humans have been facing the threat of soil desertification.

Especially in recent decades, the speed of land degradation has reached an alarming level.

Although this process has not been completely reversed, it generally happens in a long wheelbase time of centuries.

And now, an opportunity, an opportunity to change China, and even change the earth, at least the possibility, has been placed in front of everyone in the conference room.

In comparison, the exploration of the next two areas does not even seem that important.

Of course, the meeting must be completed as usual.

However, the enthusiasm of the people for discussion has cooled down a lot compared to before.

Chang Haonan naturally saw the change in this atmosphere.

So, after the last group of people introduced their work during this period, he spoke directly to wrap up:

"How about this, Researcher Zhai, you summarize the three sets of analysis and test results just now, including the original data, and give me and Chief Engineer Li a copy each, and we will do parameter fitting after we go back."

Zhai Mingguo naturally did not hesitate to Chang Haonan's request:

"We have prepared these before today's meeting. When you two leave later, the data clerk will deliver them."

Then, he changed the subject:

"In addition, Professor Chang, I see that there are many other abnormal points on the satellite map you sent. Do you need to organize a second round of exploration immediately?"

Zhai Mingguo is a serious researcher after all. Although his thoughts have flown to the Mongolian Province thousands of kilometers away at this time, and he wishes he could fly there with him, he will not throw away the work at hand.

What's more, he knows in his heart that if the desert soilification can really succeed, at least half of the credit comes from the remote sensing satellite and the high-dimensional data processing algorithm developed by Chang Haonan.

So even from his own perspective, he should help sharpen the "knife" faster before chopping wood.

However, Chang Haonan waved his hand:

"Not for the time being."

"After we go back and finish fitting, we should be able to upgrade the algorithm once, and then use the 2.0 version of the algorithm to reprocess the satellite images, and by that time there may be newer images sent back... In short, it would be more appropriate to decide on the specific tasks of the second round of exploration after a while."

At this point, he turned his head and looked at Xiao Wenchang on his right:

"Moreover, I see that Team Leader Xiao and his team have been working non-stop for a long time, and they should rest for a while, at least have a complete Spring Festival..."

The latter suddenly heard his name, and was stunned for a moment before expressing his opinion:

"Well... our team members have been used to it in the past..."

That being said, when Chang Haonan said that there was a period of rest, several members from the exploration unit still showed a relaxed expression.

If possible, who wouldn't want to stay at home for a while?

After arranging the tasks directly related to him, Chang Haonan added to Zhai Mingguo:

"Also, send a copy of today's investigation report on the permafrost conditions in the northern foothills of the Tianshan Mountains to the comrades in the railway engineering department. The last time I cooperated with the Institute of Computing Technology, I heard from them that in addition to the Qinghai-Tibet Railway, the country also has plans to build railways in the Tianshan Mountains."

"Including if there are remote sensing and geographical exploration results related to the Qinghai-Tibet Plateau in the future, you can also cooperate with them. At most, the railway system will bleed a little from the infrastructure funds..."

After some arrangements, today's long meeting finally came to an end, and everyone left the meeting one after another to leave.

However, Chang Haonan specifically called Zhai Mingguo:

"If we really want to implement this desert soilification idea, then we have no hope of staying in Beijing, and it also involves land management and agronomy. We are not experts in this area, so we still have to cooperate with some colleges and universities in the central and western regions that are closer to the desert terrain. Do you have any ideas in this regard?"

Although geotechnical science and soil science sound a bit similar, the former is earth science and the latter is agronomy, and even the major categories are different. It belongs to a field that Chang Haonan has not even touched.

Moreover, as time entered the second half of 2000, the cumulative safety test hours of WS-10 continued to break new records.

If nothing unexpected happens, WS-10 will enter the design finalization process in 2-3 months.

It is estimated that Chang Haonan's main focus will be on this matter throughout the fourth quarter.

After that, the equipment imported from Europe should also arrive, and we will start to study the topic of pulsed laser processing.

Therefore, Chang Haonan can only provide some theoretical and engineering guidance at most, and it is impossible for him to stay in Meng Province.

Zhai Mingguo's situation is similar.

So, they need help.

"I know a professor at the Meng Province Agricultural and Animal Husbandry College... er, now it should be the Agricultural University, named He Guangyou, who specializes in soil erosion. He has contacted us during field exploration before."

Zhai Mingguo immediately replied:

"Although because the platform is not very good, he has not many results, and the strength of the research team is also average, but his academic research is still relatively rigorous."

"It doesn't matter if the strength is average."

Chang Haonan doesn't care much about this:

"The main thing is to be able to complete the task with quality and quantity according to our requirements."

Zhai Mingguo nodded:

"Then let me contact him and see when he is free recently. Let's talk about it together?"

"Can."

…

Zhai Mingguo's efficiency was even much faster than Chang Haonan's estimate.

Less than a week later, he contacted the latter and said that Professor He Guangyou had arrived in the capital.

Considering that this project must be led by Chang Haonan, the three simply chose to meet in a small conference room at Beijing Hang University this time.

After a brief exchange of greetings, Chang Haonan got straight to the point and stated his idea of ​​"turning sand into soil" and introduced the theoretical basis he had previously told Zhai Mingguo and the others in more detail.

After listening, He Guangyou pondered for a long time.

To be honest, he was not proficient in these theoretical knowledge. Even though he had just listened to it once, he still felt a little confused.

But no matter what, He Guangyou still believed the names of Chang Haonan and Zhai Mingguo.

So the focus actually lies on the operation——

The desert area in central and western Mongolia Province is a terrain that he is very familiar with.

In fact, He Guangyou's hometown is in Bayannur City, near Alxa.

However, Chang Haonan has no knowledge of agriculture after all, and his ideas are almost entirely based on physics, so it will take him some time to think about how to implement the project.

"Chang Jiao, there are two things I need to say first."

After a few minutes, He Guangyou looked at Chang Haonan again.

The latter nodded and signaled the other party to continue.

"First of all, your idea just now is mainly to improve the binding force of the sand body and convert the dispersed sand into a rheological state. However, in actual production, most of the problems faced by the soil are that the agglomeration is too serious, so If we blindly increase the binding force, it may be okay at first, but it may lead to the deterioration of the soil condition to the other extreme after a few years.”

He Guangyou said:

"In addition, these soils are modified from sand, so at least in the first few years, it is difficult to grow food... In fact, considering the problem of salinity, it may be difficult to grow anything, so my suggestion is that it is best to Find a crop with relatively high salt-alkali tolerance but relatively low soil fertility requirements..."

"for example?"

Although Chang Haonan is not indifferent to grains, he has never cultivated land and has no idea about this kind of thing.

"for example……"

He Guangyou hesitated for a long time:

"I'm afraid natural crops don't have such good properties, so we may need a breeder to specially cultivate some alfalfa or legume crops in this direction..."
