"Is that okay?" Wu Bin asked.

"It's the best way to go. Firstly, mixed planting can further increase the number of soybean plants per unit land, and secondly, a large amount of nitrogen fixation effect produced by lateral rhizobia of improved soybean varieties can be absorbed by ordinary soybean varieties. Chen Cheng said.

After nitrogen fixation, two-thirds of the rhizobia enters the plant and one-third remains in the soil, just enough to provide more nitrogen and ammonia for ordinary soybeans.

This is equivalent to a good fusion of the two, and the soybean increment effect it produces cannot be underestimated.

"You're doing a good idea!"

Wu Bin sighed: "With this method, at least most of the Loess Plateau can be planted with soybeans."

I will now arrange for the provinces and cities around the Loess Plateau to start a survey of land resources suitable for planting, and then arrange for them to prepare for spring planting in three months. ”

Wu Bin hung up the phone excitedly, and Chen Cheng returned the phone to Zheng Kebo.

"Director Zheng, do you believe it this time?" Chen Cheng asked.

Zheng Kebo hurriedly said: "I believe in you myself, Expert Xiao Chen." ”

Chen Cheng smiled and turned his head to arrange follow-up work for the researchers.

Including the subsequent planting of soybeans after pollination and the cultivation methods for the next generation of soybean seed production after harvest.

After doing this, Chen Cheng packed up his things and returned to Agricultural University.

It's already winter break.

Most of the students in the school have left the school, and as long as Chen Cheng and a few people in his dormitory have laboratories and innovation factories to do, they are not going to go home for the New Year.

And Lao Xu.

After the sow successfully conceived, now her belly is getting bigger day by day, and he has a lot of work to do, and he can't leave anyone.

Chen Cheng also gave up his plan to go home for the New Year, and then locked himself in the laboratory.

On the one hand, it is to continue the previous technical research, and on the other hand, it is to organize all the papers accumulated in hand, and send them to the Transactions of the Chinese Society of Agricultural Technology.

Thirteen whole articles.

Sending thirteen papers at once may be considered a pioneering feat.

The Transactions of the Chinese Society of Agricultural Technology has now doubled in citations due to the two papers published by Chen Cheng before. It is estimated that the impact factor will go up to a higher level next year. There should be no problem getting into the top 20 in the global rankings.

That afternoon, Chen Cheng was sorting out data in the laboratory, and Wang Kai, Ding Tao, and Tang Qiang all walked in.

"Lao Chen, are you still busy?" Wang Kai asked.

Chen Cheng nodded.

"Let's go out to dinner." Wang Kaidao.

"What's the joy? Going out to eat? ”

"Let's go!" Wang Kai pulled him up from the stool.

"I don't want you to have a treat."

Chen Cheng packed up his things ignorantly and locked the door after dinner.

The group arrived at a barbecue restaurant outside.

"This is not a self-service barbecue, the consumption is very high!" Chen Cheng said.

Although he is now very "rich", the funds are all used for research, and he still spends very little.

"Let's go, Lao Xu has a treat!" Wang Kai pushed him in.

When Chen Cheng walked into the private room, he found that it was a large private room with a table of ten people.

"So many locations?" Chen Cheng asked Lao Xu, who was ordering.

"Doesn't everyone bring their girlfriends?" Lao Xu said.

Chen Chenghu painted.

"You have a girlfriend too?" He looked at the swarthy and old-looking old Xu.

Lao Xu smiled shyly and said, "Didn't you just talk about it, Brother Kai had to let me have a treat!" ”

Chen Cheng looked at Wang Kai's smiling eyes, and probably understood.

They all have to bring their girlfriends, and he doesn't have a girlfriend himself, so Wang Kaicai kept it a secret from him just now and didn't tell him the reason for eating.

"I'm sorry, I still have experiments to do." Chen Cheng was about to get up.

Wang Kai grabbed him.

"Eh, Lao Chen, we promise not to show affection. Okay, right? Wang Kai begged.

Chen Cheng sat down at this time.

Without this trick, it would be very uncomfortable if they showed affection again later like they did at the last dinner.

The problem is that Tang Qiang accompanied him last time, but Tang Qiang also fell in love last month.

Now he is the only one who is alone.

As for why Wang Kai had to invite Lao Xu to dinner today, it was because their girlfriend was also going home from vacation, so he arranged to have a dinner while everyone was there.

After a while, the girls walked in with a chatter.

The friendship of girls comes very simply, although they are of different grades and majors, but once they have a common topic, they quickly become friends.

The common topic was their roommate boyfriend.

The four girls walked into the private room, and the boys who were originally discussing the game next to each other quickly separated and gave way to their respective girlfriends.

"Stop! I recommend men and women to sit separately! Chen Cheng said loudly.

Wang Kai said with a smile: "Lao Chen, you can't be like this, you are called beating mandarin ducks." ”

"Then I'd better go back to the experiment."

"Okay. Sit apart! ”

The eight people pouted at the same time and looked at Chen Cheng sullenly.

Chen Cheng had a satisfied smile on his face.

In winter, it is really comfortable to grill meat around the stove in a private room. It's just that what Chen Cheng didn't expect was that the table was still not big enough, and the four of them were able to reach out and pick up vegetables for each other.

It's hard to prevent!

Chen Cheng took a bored sip of beer.

It doesn't taste good.

After three rounds of drinking, Wang Kai opened the chatterbox.

"Lao Chen! When are you going to talk about your girlfriend? ”

"Yes, you're so famous, there must be a lot of girls chasing you."

"I think Lao Chen is too busy. His girlfriend is his laptop, and he's almost touched by it. ”

Several roommates ridiculed, and Chen Cheng felt the strong malice of the love dog.

These people are good at everything, they just like that girlfriend to sour him.

"First of all, I want to congratulate my good brothers, you all have girlfriends."

Chen Cheng took a sip of wine, and then said: "Actually, we haven't been looking for a girlfriend because I haven't met a girl who is beautiful enough to make me tempted." ”

He made a pun on that.

The first is to explain why he hasn't been in a relationship yet, and the second is to imply that your girlfriend is averagely beautiful, at least not to the point of beauty that makes me feel tempted.

Wang Kai and the others heard that he had something to say, and their faces were embarrassed.

After a while, Wang Kai patted his head.

"No, you're a single dog, what's the right to say that our girlfriend isn't pretty enough?"

Ding Tao, Lao Xu and others also reacted, and hurriedly followed.

"yes. You don't have a girlfriend. ”

"So that's why you're single?"

Wang Kai raised his hand to interrupt them, and then said, "Lao Chen, if you want to say that your agricultural skills are very good, I have no doubt about this. But to say how beautiful a girlfriend you can find, I don't believe it. ”

Wang Kai thinks that Zhang Mengmeng, the beauty of his propaganda department, is the most beautiful.

"I don't believe it either!" ×3.

Ding Tao: They also think that their girlfriend is the most beautiful.

Love is blind.

"What if I find a beautiful girlfriend?" Chen Cheng asked rhetorically.

Wang Kai snapped a bottle of beer on the table.

"I take a sip of a beer."

"Two bottles for me!"

"Three bottles for me!"

Then Chen Cheng's phone rang.

It was Han Qi who called.
