Chapter 1146 Phase I Project, 40 Million Acres!

What was originally thought to be a huge obstacle has now been solved with just one sentence.

For Zhuang Bingchang, there are definitely surprises.

But I still have more doubts in my heart.

It's not that I don't believe in Chang Haonan's level.

It is true that the results given by the other party are a bit too accurate.

Both base materials, especially sodium carboxymethylcellulose, are not a common curing agent used in such studies.

It's not even a common chemical product.

Although "modified cellulose" belongs to a relatively popular category of biomass products, for now it can only be regarded as a promising future.

To be able to specify a particular category so accurately must go through quite rigorous arguments.

However, as the front-line person in charge of the experimental fields in Mongolia Province, Zhuang Bingchang knew very well that Chang Haonan had not conducted similar soil modification experiments——

Not to mention local.

From 2000 to now, the latter has only asked him for soil samples twice.

It's not just for experiments, but for soil mechanics modeling and improving the geological surface database.

So how did this argument process... come about?

Zhuang Bingchang, who was a little confused, hesitated for a moment and asked cautiously:

"Academician Chang, it would be inconvenient for me to reveal why these two main ingredients are used?"

In practice, of course it is inconvenient.

Inspiration is inspiration, but being able to transform inspiration into concrete results in just a dozen hours is thanks to the help of the system.

He directly skipped many unnecessary trial and error steps, analyzed and calculated the interaction between different hydrophilic/hydrophobic groups and the surface of soil particles at the molecular level, and finally screened out the best solution in terms of both cost and performance. A relatively balanced result in all aspects.

Even for Chang Haonan himself, this process takes a while to fully digest. For outsiders, it is extremely tearing, and it is impossible for anyone to understand it.

Fortunately, Chang Haonan had already thought of another explanation while waiting for the results.

“A few years ago, didn’t we establish a soil database for various regions in Mongolia? A while ago, when I was routinely reviewing the literature, I found that foreign scholars used polyvinyl alcohol curing materials to treat a soil with similar characteristics. Transformation was carried out...Although it failed, the failure cannot be explained by the direct polarity combination theory that I was used to..."

As he spoke, he opened a paper on his computer and the log file of the last round of calculations a few hours ago:

"I used the soil database we established to conduct several theoretical reductions on his experimental results, and finally determined that there are four main mechanisms of action of water-soluble or semi-water-soluble polymers on sandy soil micelles."

“First, by replacing cations on the surface of the micelles, the thickness of the electric double layer is thinned, increasing the attraction energy between particles, and promoting aggregation between particles; second, the carboxyl groups on the molecular chain and the hydroxyl groups on the soil surface form hydrogen bonds to strengthen the soil. Structural stability…”

"The third is that the hydrophilic groups of the polymer are adsorbed on the surface of the soil particles, and the hydrophobic groups repel the infiltration of water, thereby enhancing the water stability of the soil; the fourth is that the soil particles overlap each other through polymer chains to form a network structure, which further plays a role in Reinforcement effect.”

"After the main mechanism is determined, the only thing left is to perform calculations at the molecular level. This is a more time-consuming process, but fortunately the principle is not complicated... Just repeatedly sample the configuration space of the system particles, calculate the total energy, and then Find the most probable conformation and thermodynamic equilibrium properties of the system..."

"..."

This set of rhetoric highlights nine truths and one falsehood.

If you come to an expert in computational chemistry or computational materials science at the same level as Chang Haonan, you may be able to hear some problems.

For example, the last calculation process is a task that is simply impossible for today's computers to complete within a limited time.

Unfortunately, in this day and age, it may not be easy to find such a number one person.

As for Zhuang Bingchang, who was born in agriculture, he gave up completely when he heard the middle part.

He even felt a little regretful for the first time——

If I had known this, I should have studied mathematics in depth when I was young...

But the feeling is almost fleeting.

After all, if you can’t do mathematics, you just can’t do it.

"All right……"

He decided not to delve into the issue further:

"Then our next step is to go back to the experimental field and conduct sand modification tests in blocks?"

In most cases, even if the main ingredients have been confirmed theoretically, the suspension system after the cross-linking reaction is still too complex, so the specific ratio and preparation method still need to be carried out through experiments.

Of course, with theoretical guidance, the efficiency will definitely be much higher than aimless sifting.

However, Chang Haonan gave a refusal almost without thinking:

"No, let's not rush this yet."

Zhuang Bingchang was about to get water when he suddenly froze:

"Have you calculated the detailed ratio?"

"That's not true...I'm not that powerful yet."

Chang Haonan smiled helplessly and quickly waved his hand:

"It's just that before you return to Mongolia, there is one more thing that needs to be done."

Zhuang Bingchang curled his lips secretly, thinking not necessarily, what you suddenly brought out was not enough...

But on the surface, he still acted like he was listening carefully.

"With these current results, we can no longer stay in the small experimental field."

Chang Haonan turned his attention back to the screen:

"I am going to submit a report to my superiors to apply for increased investment in research and development of supporting technologies related to sand conversion, so I need your help to complete a report..."

…

If Chang Haonan's dual academician title has brought him any substantial benefits.

So the most obvious one is definitely that he has the right to bypass the intermediate levels and submit suggestions or applications directly upwards.

Of course, high-level leaders have a lot to deal with every day, so if you just use any trivial matter to cause trouble for others, don't blame the secretarial department for blocking your materials.

Most of the time, you still have to follow the normal step-by-step declaration process——

But this time the project is related to the jobs of 1.3 billion Chinese people.

It is simply not something that the Industrial Construction Committee can decide.

Even on the attendance list for the project demonstration meeting determined half a month later, Li Zhongyi's name could not even enter the first row of the list...

Chang Haonan is already used to this.

But Zhuang Bingchang is different.

Although he was a well-known professor at the Academy of Agricultural Sciences in the past, this was the first time he had experienced such a big scene...

In the side hall temporarily used for rest, Zhuang Bingchang, who was about to take the stage, held a manuscript in his hand and kept pacing back and forth.

"Academician Chang, if the leader later asks about the solidification principle..."

Chang Haonan, who was sitting on the sofa, interrupted him with a wry smile:

"Professor Zhuang, this is the third time you have asked me the same question in the past half hour..."

"In short, you should remember that first of all, the leader is a layman in the fields of chemistry and agronomy. It is unlikely that he will ask such a specific technical question. Secondly, even if he does ask, unless it is related to breeding, I will answer it... …You just need to summarize and report on the work of the past few years according to the rehearsals of the past few days.”

Zhuang Bingchang nodded slightly awkwardly, then took out his handkerchief and began to wipe his sweat:

"To be honest, Academician Chang, there was no transition at all. It was like this from the beginning. I was really nervous..."

"..."

If this continues, Chang Haonan has no doubt that the other party will ask the same or similar questions for the fourth time.

Fortunately, a staff member came in a few minutes later and informed the two that they could play.

…

This kind of high-level meeting is not open to the public, but there is not much red tape.

In particular, Chang Haonan is still a famous figure.

After just a brief self-introduction, we got to the point:

“As we all know, in recent years, due to human engineering activities and changes in the natural environment, various ecological and environmental problems have arisen in the originally fragile ecological functional protection areas. Among them, desertification is caused by soil loss and degradation after the destruction of slope vegetation. More prominent.”

“In particular, Xinjiang, Tibet, Gansu, Qinghai, and Mongolia account for 95.64% of the total desertified land area in the country, which has seriously restricted the economic and social development of these areas and is not conducive to the promotion and implementation of the Western Development Strategy..."

"Since 2000, the project team led by me and Professor Zhuang Bingchang of the Jilin Academy of Agricultural Sciences has been conducting a four-year pilot project on desert soil transformation in western Mongolia Province. So far, it has achieved theoretical and mu-level small-scale testing remarkable results..."

"..."

In front of the leaders, Chang Haonan naturally cannot use too much space to explain such advanced contents as shear rheology constitutive model, enthalpy control strategy, chemical bond formation mechanism or colloidal particle self-assembly process.

Together with Zhuang Bingchang, I briefly introduced the entire research and calculation process, and then switched to the core topic before the first person dozed off:

“I believe that there are sufficient conditions now. Based on our transformation plan and the actual situation, the Horqin Sandy Land, Hunshandake Sandy Land, and Hulunbuir Sandy Land located in eastern Mongolia Province have been significantly degraded in the past decade. Three agricultural production areas are undergoing demonstration transformation...but the specific scale of the pilot still needs to be determined by the leaders..."

When he said this, not to mention the leaders below, even Zhuang Bingchang couldn't help but show an expression of astonishment.

He had indeed heard Chang Haonan say that he needed to find his superiors to increase investment.

But I never expected it to be an increase in this sense.

By analogy, it is equivalent to jumping directly from the past small trial stage to industrial trial production...

The leaders in the front row who could participate in the final decision also looked at each other, and then discussed in low voices for a long time.

After a while, one of the representatives asked:

"Before the meeting, I read the information about your experimental field in western Mongolia Province. Although it is only less than 100 acres planned at this stage, the surrounding area is very empty... Why not choose to continue to expand at the original location, but to move to Mongolia Province? east?"

Regarding this issue, Chang Haonan has already prepared a draft:

"After all, agricultural production is different from technological experiments that pursue the ultimate limit. Even with qualified soil conditions, it still requires suitable light and precipitation... The eastern part of Mongolia Province belongs to the northeastern region, and the precipitation is almost twice that of the west, making it more suitable for agricultural production. True large-scale planting, with greater potential to increase production, has the potential to alleviate the shortage of cultivated land in our country..."

"Relieving the tension on farmland..."

The leader who asked the question just now shrank his pupils and almost lost his dignity.

After a few breaths, he sat up straight and his tone became serious:

"Comrade Chang Haonan, do you know... the weight behind this sentence?"

Among 100 research projects in the field of environment and agriculture, I am afraid that 101 will mention similar statements.

But it is one thing to brag in the project proposal, and it is another to say it in front of so many high-level leaders.

The issue of jobs.

No matter how much attention is paid, it is not too much.

Chang Haonan nodded firmly.

"Of course."

Until this time, everyone finally realized.

The "large scale" mentioned by Chang Haonan may be much more exaggerated than their previous estimates.

"Comrade Chang Haonan, I hope you will carefully consider the following question before answering."

The leader leaned forward slightly and cast a sharp gaze at Chang Haonan opposite:

"If you don't consider the investment and other costs, how large an area do you think this demonstration transformation you just mentioned has the potential to achieve?"

In fact, Chang Haonan has really calculated this matter in the past few days.

The final result even feels a bit exaggerated to him.

So, it has been calculated more than once.

But since the leader asked you to consider it carefully, it would be inappropriate to blurt it out.

Therefore, Chang Haonan deliberately lowered his head and pondered for three minutes:

"If all three pieces of sand are counted, the conservative estimate is... about 40 million mu!"
