Chapter 1145 The Last Piece of the Puzzle in Desert Transformation

Take a break in the middle to verify the sudden inspiration.

Listen, does this sound like what people say?

The last person who used this sentence pattern and was widely circulated was probably Guan Erye when the eighteen princes challenged Dong.

"Pour down the wine. I'll come as soon as I leave."

Fortunately, this kind of internal closed-door meeting actually has no adjournment.

Everyone is leaving today, just meet up another day.

Considering that the person who said this was Chang Haonan after all, everyone finally accepted his request.

After leaving the Industrial and Construction Committee, Chang Haonan contacted Zhuang Bingchang almost immediately.

Fortunately, the latter was not experimenting in the deserted Mongolia Province at this time, but cultivating the latest batch of sand-fixing crops at the Jilin Provincial Academy of Agricultural Sciences.

Therefore, I was able to fly to the capital overnight with the research results so far...

When Zhuang Bingchang arrived at the Torch Laboratory, Chang Haonan had just finished working all night and returned to the office——

Although the degree of polymerization and group ratio of the polymer have not been completely determined, after one night of calculations, he has at least determined the feasibility of the idea of ​​hydrophobic main chain + hydrophilic groups.

We even got some unexpected surprises in the process...

…

As soon as the two met, Zhuang Bingchang took two steps forward enthusiastically:

"Academician Chang, I finally have the opportunity to congratulate you in person on your successful election..."

"..."

Chang Haonan has basically been active in Beijing and Haojing in recent years, while Zhuang Bingchang's workplace is in Mongolia and Jilin provinces.

The two of them usually communicate through emails and phone calls, and they only see each other once every year when reporting.

But because at the end of 2003, Chang Haonan was in a hurry to go to Haojing to deal with the project, so we actually didn't see each other for two years.

During the chat, Zhuang Bingchang also inadvertently revealed that his hometown had hoped to introduce him back to Changyang Agricultural College as a talent a few years ago, but considering that many half-way research projects are still in Jilin Province, and with Chang Haonan The cooperation was also in the name of the Jilin Provincial Academy of Agricultural Sciences. It was too troublesome to change places in the middle, so I finally refused.

Chang Haonan dealt with it cheerfully, but he said in his heart that you were lucky not to go back, otherwise if something unexpected happened, all my hard work over the years would have been in vain...

After some pleasantries, the two finally got down to the topic:

"Professor Zhuang, to what extent is your crop breeding...probably?"

Zhuang Bingchang is well-known in the industry as a soybean breeding expert, but in fact, his team no longer only focuses on a single crop.

In particular, the resources provided by Chang Haonan, no matter how few, are still richer than when he was at the Academy of Agricultural Sciences, so he actually led several teams from different institutions to select multiple types of soil-fixing and plants at the same time.

Zhuang Bingchang also quickly got into the mood when talking about business.

"It went much smoother than expected..."

As he spoke, he took out a notebook with obvious signs of use and a USB flash drive from his briefcase——

After entering the 21st century, things like floppy disks finally gradually withdrew from the stage of history.

Chang Haonan plugged the USB flash drive into the computer, which contained dozens of test record files.

“We have optimized several crop varieties with outstanding root strength, including Elymus elegans, naked oats, and Artemisia vulgaris... The roots of this type of plant can produce friction reinforcement and grid wrapping effects on the soil, providing additional cohesion and reduce the lateral shear force on the soil.”

Zhuang Bingchang easily opened the notebook to the page he wanted, and pointed out the data recorded on it to Chang Haonan:

"In addition, the hydraulic effect of the plant itself can also regulate the transport and exchange of soil moisture between the atmosphere, plants and soil, changing the shear strength of the soil... In other words, it can directly enhance the kind of water you proposed before. Universal binding binding force..."

“After two to three rounds of improving soil conditions, we can use the drought-tolerant, salt-alkali-tolerant alfalfa and soybean varieties we are cultivating to start restoring land fertility..."

Upon hearing this, Chang Haonan immediately interrupted the other party:

"You mean, the previous three rounds of space breeding...are considered to have yielded results?"

The effectiveness of space breeding depends largely on luck

Although with a large enough base, it is possible to find a few mutant traits that are beneficial to human agriculture, but if two requirements are specifically selected, the probability of success is actually not high.

Therefore, before this, the breeding work of these two types of leguminous plants was also another long-standing difficult problem besides the screening of curing agents.

"That's right..."

Zhuang Bingchang nodded hesitantly:

"We were lucky. Among the second batch of seeds that came back, we found several typical traits that we had been looking for before. We also happened to find wild soybeans that met the requirements during that time. What's even better is that they did not contain Monsanto's application. Patented marker gene..."

"It's just that the varieties currently cultivated have strong survivability, but they have almost no yield..."

Obviously, as a crop breeding expert, he still hopes to find products that have both economic and ecological benefits.

But for Chang Haonan, who is in urgent need of results, this is already an unexpected surprise.

"That's enough...that's enough."

Chang Haonan raised his hand slightly to indicate that this was not a problem.

Then he continued to ask:

"Have you done the whole process test of the improvement plan?"

"Yes."

Zhuang Bingchang replied:

"Since the year before last, we have conducted modification tests in 14 areas in the western part of Inner Mongolia Province, and we have now entered the third round... The main problem we found is that this process can only be used to save existing cultivated land or grassland that has not yet completely degraded into deserts, but it is powerless for sandy land that has completely degraded."

"We have tried to use several typical materials such as polyacrylate, vinyl acetate, and polyacrylamide for chemical sand fixation, but the first two materials will quickly lose water after absorbing enough water, resulting in a reversible sand fixation effect... Although polyacrylamide and polylactic acid can be used after absorbing water, they can only provide a constraint torque once. Once they lose water during the solidification process, all previous efforts will be wasted..."

"..."

Usually, as the person in charge of the project directly leading the project, he cannot show too much pressure in front of his colleagues.

Even if there is a problem with the experiment, he has to take the initiative to relieve everyone's pressure.

In front of Chang Haonan, there is no such concern at all.

Therefore, this complaint can be said to be very refreshing.

Listening to the difficulties mentioned by Zhuang Bingchang, Chang Haonan was expressionless at first.

But at some point later, he couldn't hold it back and smiled directly.

This scene scared Zhuang Bingchang, who was finishing his report:

"Academician Chang, you..."

"Nothing..."

Chang Haonan waved his hand:

"It's just that I can help you put together the last piece of the puzzle that you were missing before..."

"Hmm?"

The worry in Zhuang Bingchang's eyes instantly turned into surprise.

You know, he had already prepared himself to stay in Meng Province for more than ten years.

"Come and see this."

Chang Haonan said as he opened another file on the computer.

That was the result of his hard work in the computer room last night:

"According to my calculations, after sodium carboxymethyl cellulose and polyacrylamide are used as the main materials and configured in a certain proportion, they can provide higher bonding strength and better hydrophilicity through physical cross-linking with other water-soluble polymers in the water system, thereby strengthening the universal binding force between loose sand particles."

"At the same time, because the long-chain structures of the two main materials are composed of hydrophobic groups, they can also ensure a certain aging resistance, and will not become a one-time sand fixation agent like polyacrylamide."
