Chapter 860: Change the world
For hundreds of thousands of years.
It can even be said that since the emergence of large-scale civilization.
Humanity is facing the threat of soil desertification.
Especially in recent decades, the rate of land degradation has reached an alarming level.
Although this process is not completely reversed, it usually occurs during the long wheelbase time measured in centuries.
And now, an opportunity, an opportunity to change China and even the earth, at least the possibility, has been placed in front of everyone in the conference room.
In comparison, the exploration situation in the latter two areas does not even seem that important.
Of course, the meeting will definitely continue as usual.
However, everyone’s enthusiasm for discussion has cooled down a lot compared to before.
Chang Haonan can naturally see this change in the atmosphere.
So, after the last group of people introduced their work during this period, he directly finished:
"Let's do this, Researcher Zhai, you just analyzed the three groups Summarize the test results, including the original data, and give them to Mr. Li and me to make a copy. We will do some parameter fitting after we go back.”
Zhai Mingguo naturally had no problem with Chang Haonan’s requirements:< br>
“We have prepared these before today’s meeting. A document clerk will bring them over when you two leave.”
Immediately afterwards, he changed the topic:
"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 immediately? Exploration? "
Zhai Mingguo is serious about research after all. Although his thoughts have flown to Mongolia Province thousands of kilometers away at this time, and he wishes others could fly there with him, he will not abandon his hands because of this. His job was thrown away.
What's more, he also knew in his heart that if the desert soilification was really successful, at least half of the credit would come from the remote sensing satellite and the high-dimensional data processing algorithm developed by Chang Haonan.
So even from his own point of view, he should help sharpen the "knife" faster before chopping wood.
However, Chang Haonan waved his hand:
“No need for the time being.”
“When we go back and finish the fitting, we should be able to upgrade the algorithm once and then reprocess it with version 2.0 algorithm. Satellite images will be taken again, and updated images may be sent back by then... In short, it will be more appropriate to decide on the specific tasks of the second round of exploration after a while."
At this point, he continued. He turned to look at Xiao Wenchang on his right:
"Besides, I think Team Leader Xiao and the others have been working continuously for a long time. They should need to rest for a while, at least to have a complete Spring Festival... …”
The latter suddenly heard his name, and was stunned for a moment before expressing his position:
"Is this...our team members were used to it in the past..."
That's what he said , but when they heard Chang Haonan say that they had some rest time, several members from the exploration unit still showed relaxed expressions.
Who wouldn’t want to stay at home for a little longer if possible?
After arranging tasks that were directly related to him, Chang Haonan added to Zhai Mingguo:
"Furthermore, I would like to send a copy of today's inspection report on the permafrost conditions at the northern foot of the Tianshan Mountains to the comrades in the railway engineering department. When I cooperated with the Institute of Computing Technology last time, I heard them say that in addition to the Qinghai-Tibet Railway, the country also has The plan to build a railway in the Tianshan Mountains. ”
“Including if there are remote sensing and geographical exploration results related to the Qinghai-Tibet Plateau, we can also cooperate with them. At worst, the railway system will spend some money from infrastructure funds. ..."
After some arrangements, today's long meeting finally came to an end, and everyone left the table and prepared to leave.
However, Chang Haonan stopped Zhai Mingguo specifically:
“If we really want to implement this idea of desert soilization, then there is no hope for us to stay in the capital, and this It also involves land management and agronomy. We are not experts in this area, so we still have to cooperate with some colleges in the central and western regions that are close 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 agricultural science. They are even different categories. They are fields that Chang Haonan has not had much contact with.
Moreover, as time entered the second half of 2000, the cumulative safety test hours of Turbofan 10 continued to break new highs.
If nothing unexpected happens, in another 2-3 months, the turbofan 10 will enter the design finalization process.
It is estimated that throughout the fourth quarter, Chang Haonan's main focus will be on this matter.
After that, the equipment imported from Europe should also arrive, and we should start studying the subject of pulse laser processing.
Therefore, Chang Haonan can only provide some theoretical and engineering guidance at most, and it is impossible for him to stay in Mongolia.
The situation of Zhai Mingguo is similar. So, they need helpers.
"I know the Mongolian Agriculture and Animal Husbandry College...well, he should be a professor at the Agricultural University now, his name is He Guangyou, who specializes in soil erosion. He was doing field exploration with us before. I had contact with him at that time.”
Zhai Mingguo immediately replied:
"Although because the platform is not very good, he has not achieved many results and the strength of the research team is average, but his scholarship is still relatively rigorous."
"It doesn't matter if the strength is average."
Chang Hao Nan doesn’t care much about this:
“The main thing is 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 together?"
"Okay."
......
Zhai Mingguo's efficiency, 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 went 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 others in more detail.
After listening, He Guangyou pondered for a long time.
To be honest, he is not proficient in these theoretical knowledge. Even after hearing it just once, he still feels a little confused.
But no matter what, He Guangyou still believed the names of Chang Haonan and Zhai Mingguo.
So the focus is actually on the operation -
The desert area in the central and western parts of Mongolia Province is a terrain that he is very familiar with.
In fact, He Guangyou’s hometown is 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 The agglomeration situation is too serious, so if we blindly increase the binding force, it may be okay at first, but it may cause the soil condition to deteriorate 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 Can we find a crop with relatively high salt-alkali tolerance but relatively low soil fertility requirements..."
"What about?"
Although Chang Haonan is not indistinguishable from grain to grain, he has never farmed before and has no idea about this kind of thing.
“For example...”
He Guangyou hesitated for a long time:
“Natural crops may not have such good properties, so we may need a breeder to specialize in Cultivate some alfalfa or legume crops in this direction..."
