"Growing rice in the desert?" Li Changsheng was really shocked by the teacher.

"Yes, but because the desert is formed for a very diverse reason, the best test site is in the saline soil at the moment. Yi Daoping nodded, and then pointed to the genetic sorting method on the small blackboard and said:

"Its real name is saline-alkali tolerant rice, and it is a special rice that can be grown in saline-alkali land such as seaside tidal flats and swamps. The environment in which it grows is not really like normal rice and it is immersed in seawater or sea for a long time, but it is not afraid of short-term immersion in seawater. If we can really plant this seawater rice in the seawater, then our East China Sea and Bohai Sea can all be used as granaries. ”

Li Changsheng nodded, and then continued to ask, "But teacher, why does seawater rice attract your attention?"

Yi Daoping seemed to have expected Li Changsheng to say this, and said: "There are 950 million hectares of saline-alkali land in the world, 320 million hectares in Asia, and 100 million hectares (1.5 billion mu) of saline-alkali land in China, of which 280 million mu can be developed and utilized. There are more than 200 million mu of saline-alkali land that can be used to grow seawater rice in China, and according to the calculation of the future yield of 200-300 kilograms per mu, it can increase the grain output by tens of billions of kilograms and feed about 200 million more people. ”

"Just now the institute called me and said that it had analyzed its chemical equation, and I will write it to you now. On the other half of the small blackboard, Yi Daoping writes the chemical equation for saline-alkali tolerant rice.

"Changsheng, can you understand these genetic maps and chemical equations? You can point out what you don't understand, and I can teach you. ”

Li Changsheng shook his head, he is now level 4 in chemistry and level 5 in biology, this kind of map is not difficult for him at all, but he began to figure it out:

"Teacher, I can understand these diagrams, you don't have to worry. I'm more concerned about what you said about growing rice in the desert, what is the specifics?"

Yi Daoping took out a large stack of materials from his briefcase and handed it to Li Changsheng to read.

According to the information, most of the saline land is in the desert, because the salt content is too high, it is difficult for fish and plants to survive, and only a few plants can survive.

If seawater rice wants to be planted on it, it must be planted on this sand.

The question arises, how can it be planted on sand?

You must know that as long as a gust of wind blows in the desert, the sand can run with it, which is because it is not stable, and there is another more important factor, the sand cannot hold water.

After Li Changsheng finished reading it, he was silent, thinking in his head.

If we want to grow seawater rice in the middle of the desert on saline soil, we have to overcome this problem. Our institute has invited experts and professors from universities all over the world, including experts in mechanics specializing in soil constraints, as well as professors from materials disciplines, biochemistry, biomathematics, biological side blood measurement, ecology, genetics, etc.

This time, we have gathered a large number of people to solve this problem, and I believe that we will be able to overcome this problem within a year. ”

Yi Daoping's tone could not hide the excitement in his heart, this time the country mobilized so many technicians to support him in the development of saline-alkali tolerant rice, he must not live up to the country's expectations.

For this project, the state attaches great importance to it, and the research funds alone have been earmarked for one billion yuan, and research units and university professors across the country can be mobilized at any time, and thousands of people have been mobilized to study how to grow plants on the sand alone, and the state has fully supported what equipment is needed.

It can be said that the soldiers are strong, waiting for the day when they will conquer it.

"Tuk Tuk Tuk~"

There was a knock on the door to the study.

Yi Daoping said "Please come in", and saw Su Xuexian walking in with food.

"Mr. Yi, you haven't eaten tonight, let's eat a little food first. ”

Yi Daoping nodded with a smile and said:

"Okay, thank you Jingru. ”

And Li Changsheng on the side suddenly jumped up and shouted loudly: "Teacher, I have a way, I know what to do to make rice grow on this sand." ”

"Oh?" Yi Daoping looked at Li Changsheng suspiciously.

"I'll write it out for you. Li Changsheng hurriedly found a blank piece of paper and wrote on it.

And Su Xuexian, who had just brought in the food, was contemptuous, and she secretly said in her heart: Planting rice on the sand? This guy is really good at bragging, who doesn't know that planting rice requires a lot of water, and the sand does not store water at all, how can these two unrelated things be combined?

Yi Daoping saw what Li Changsheng wrote, and his heart was even more shocked, their research project has thousands of experts and professors, sufficient funds, and countless research equipment, even so, they have not found any clue to solve this kind of world problem, and Li Changsheng, this guy, actually just read the information, and in less than two minutes, he had a very genius idea.

What Li Changsheng wrote was a special adhesive formula, like a glue, gluing each sand together for a certain period of time.

In other words, the sand used to be a fishing net with a very large gap, and when the water was poured on it, it would flow away directly, leaving not a drop left.

And Li Changsheng's adhesive is like replacing a fishing net with a quilt, and if water is poured on it, the cotton inside will absorb a lot of water and retain a lot of water.

"Genius! genius idea!" Yi Daoping felt his heart beating rapidly.

Li Changsheng's idea was too amazing, and the most terrifying thing was that he was writing the formula for this special adhesive.

He's actually writing recipes?

How did he do it?

"Teacher, I'm done. Li Changsheng threw away the pen and handed the formula directly to his teacher for review.

"Wait, I just have the ingredients you need for these recipes. Yi Daoping became excited, he hurriedly took off the key to the warehouse, held the formula written by Li Changsheng tightly in his hand, and strode out.

"Hey, what are you doing? What are you planting rice on the sand? Are you kidding?" Su Xuexian was angry when she saw Li Changsheng, this guy was annoying to look at.

"Alas, I've said it a few times, if you're ugly, read more. Why can't rice be planted on the sand?" Li Changsheng asked rhetorically.

"Hmph, let me tell you, I'm a graduate student at Jingcheng University, dare I say I haven't studied?" Su Xuexian snorted angrily, crossed her hands on her chest and said, "Are you that little cookie?"

"Five hundred years ago, before the airplane, people were like, 'How can a man fly in the sky?'" Li Changsheng fought back.

"You ......" Su Xuexian shook her big murder weapon angrily, and then turned her head; I don't fight with you. Anyway, it is impossible to grow rice on the sand. ”

"Hey, we'll see. Li Changsheng smiled faintly.

And in the aisle, there was already the sound of Yi Daoping's footsteps.
