It wasn't until almost ten o'clock that the reporters and onlookers dispersed.

Chen Cheng saw that Huang Weidong was still with him, looking like he wanted to speak and stopped.

"Mr. Huang, if you don't go back to the factory to arrange delivery, what are you doing here?" Chen Cheng asked.

Huang Weidong said with a smile: "I have already arranged the delivery. I have something to discuss with you. ”

"What's the matter?"

Huang Weidong looked at him longingly and said, "This super urease microbial technology, can you cooperate with our Hanxi Nongfeng to engage in market transformation?" ”

Chen Cheng thought for a while and said, "As long as it is beneficial to the farmers' production and harvest, I will consider it." If I want to transform, I will arrange for Wang Kai to dock with you. You go back first. ”

Huang Weidong seemed to have received great benefits, nodded and left in a hurry.

sent everyone away, leaving only Chen Cheng and the four people in his bedroom, and Uncle Li and his wife standing on the edge of the soybean field.

After the excitement, the fields of the countryside returned to silence, and the sound of grass and seedlings pulling out joints could be heard in the breeze.

"Xiao Chen, what about the other half of the soybean seedlings?" Uncle Li asked anxiously.

Now the whole field is green and yellow, and it is very dazzling to look at.

Chen Cheng squatted in front of the yellowed autumn soybean seedlings, and the system's prompt sounded.

[Drought problems and excessive urea application problems were detected in autumn soybean seedlings]

"Urea overdose?"

Chen Cheng frowned, probably guessing that Chanda and they deliberately increased the amount of sprinkling yesterday in order to make their compound fertilizer effective.

"Uncle Li, the urea in your field has been excessive, you can't add urea anymore, I'll get you a packet of super urease microorganisms later, you can mix it with soil and sprinkle it in." The effect should not be bad. ”

Uncle Li showed a reassuring smile and praised vigorously: "It has to be you Xiao Chen, as long as you make a move, there is no problem that cannot be solved." ”

Chen Cheng leaned over to the soybean seedlings that had been sprinkled with super urease microorganisms, pulled one out directly, and checked its rhizomes.

Because the system says that this super urease microorganism can symbiosis with soybean rhizomes.

This phenomenon he needs to observe and document.

At the moment when the soybean seedlings approached in front of him, the system prompt sounded in his head again.

[Ding, new autumn soybean varieties detected]

"What? Another new variety? ”

In addition to being excited, Chen Cheng found that the number of new varieties had reached 4.

In other words, he is still one new variety away from meeting the upgrade requirements of the system.

What happens when the system is upgraded?

Chen Cheng's heart was full of anticipation.

He exited the system, handed the soybean seedling to Ding Tao, and told him to do a section of the rhizome as soon as possible after returning to the laboratory.

Uncle Li and the existence of their village tried their best to keep Chen Cheng and them for lunch, but Chen Cheng refused their kind invitation on the grounds that he was rushing back to do the experiment.

Back in the laboratory, Wang Kai went to buy food, and Ding Tao and they began to do slice experiments.

The sectioning experiment is to cut the research target into very thin slices, pick out the thin and complete sections, put them on a glass slide filled with water, and observe them under a microscope.

Sectioning is a simple but important observational experimental method to study the relationship between the microstructure of materials and their composition and properties.

Chen Cheng was not idle, went back to the inner room and sat down, and then called up the super agricultural technology system.

"View new breed properties."

As an important food and cash crop, soybean is not only widely cultivated, but also an important economic resource.

Chen Cheng felt that he would conduct in-depth research in this area in the future, so he attached great importance to the attributes of this new autumn soybean variety.

[Please name the new variety first]

"Let's call it 'Chen Dou No. 1'!"

Soon, the system gave a list of attributes of Chen Dou No. 1.

[Variety: Chen Dou No. 1]

[Yield: 260 kg per mu]

[Characteristics: It has the dual characteristics of super urease microbial symbiosis and rhizobia symbiosis, the rhizome is strengthened, the ground is deeper, and it has the characteristics of drought resistance and rich nutrients]

[To be developed: the new generation can also increase the yield by 20%, and shorten the growth cycle by 15%]

[Weaknesses: It still has high soil requirements and poor salinity tolerance of ordinary soybeans]

Chen Cheng nodded.

It seems that the new variety was obtained this time because the symbiotic super urease microorganism promoted the evolutionary development of its rhizome and acquired this genetic trait.

In other words, even the offspring of this batch of autumn soybeans, without the addition of super urease microorganisms, have the characteristics of drought resistance and nutrient richness.

However, from the current point of view, this new variety still has many weaknesses, and the yield and growth cycle can be further improved.

That's what he's going to do next.

Watching the 3D virtual 'Chen Dou No. 1' soybean seedlings being projected onto the display wall, Chen Cheng not only sighed.

Unexpectedly, in just one month, he experimented with four new products.

Although this is an absolute miracle in the history of agricultural technology research, Chen Cheng still feels that he is not proud.

The country's 300 million peasants have to cultivate 1.8 billion mu of cultivated land and feed 1.2 billion mouths that are waiting to be fed. How difficult is it?

Just four new varieties are not enough for the peasants to live a good life, nor is it enough for the people of the whole country to have no worries about food and clothing.

The grain is not the lump of rice that is served in the bowl every day, but the harvest of spring and autumn, fighting with the sky, pests and diseases, and with soil and sweat.

They never come from as easy as they seem.

Chen Cheng sighed and exited the system and went out for lunch.

Wang Kai, who came back with a few bags of rice, used his mobile phone to read the news while walking.

The news of their press conference will undoubtedly be the most exciting, and he can't wait for a moment.

Sure enough, almost all the browsers pushed news about their launch event. The title is also one more UC than the other.

He read it to a few people as he read it.

[Shocked! Twenty-two-year-old genius invented super urease microbes】

[The weather is dry, it doesn't exist, we have super agricultural geniuses!] 】

[The peasants of Hanxi Province are saved! The autumn soybeans of Hanxi Province are saved! 】

[A young man who is not afraid of people's words and only wants a good harvest for farmers, what are the sad stories behind him]

[The general manager of Huanong Group Branch promised that compound fertilizer would only sell for 100 yuan a bag! 】

Regarding the last news headline, Chen Cheng felt that he was not exaggerating.

After reading the title, Wang Kai leaned over, blinked his eyes and asked, "Lao Chen, what is the sad story behind you?" ”

"I'm very upset to meet you." Chen Cheng scolded him.

Wang Kai didn't mind, put his arm around his shoulders and said, "Lao Chen, you are now a celebrity in the whole Hanxi Province, and you will soar in the future, don't forget a few of our brothers." ”

Chen Cheng glanced at him and said, "Huang Weidong has appointed you as the vice president of sales of Hanxi Nongfeng Company, and you still mention Huang Tengda to me?" ”

Wang Kai smiled: "Thank you Lao Chen, it's all thanks to you." ”

"Really? Brother Kai, you are so good! ”

Ding Tao and Tang Qiang also came over and asked Wang Kai about the details of this matter. Where would Wang Kai let go of this opportunity to fill the cup, and blew it on the spot.

Chen Cheng shook his head, silently laid out the meal for them on the table, and put chopsticks on it.
