Scholars in the courtyard

Yangjiazhuang.

When Yang Xiaotao drove back, it was already past three in the afternoon.

The car stopped at the entrance of the brigade, and the strong New Year atmosphere could be felt as soon as he got off the car.

"You came back at the right time, our family is killing chickens, don't leave tonight."

Yang Dazhuang said happily when he saw Yang Xiaotao coming down.

These days, people say that chicken butts are banks, and old ladies are bank presidents.

This shows the status of chickens in people's hearts.

Especially in rural areas, it is an important channel for farmers to improve their lives and provide economic sources.

So it is rare to kill chickens to entertain guests during the New Year.

Of course, rare is not nothing.

Some wealthy and capable families will also raise a few roosters to improve their lives.

Because of the relationship with the farm, Yangjiazhuang is like an independent individual in this world.

In addition to completing the breeding work required by the superiors, the production income does not need to be handed in.

That is, Yangjiazhuang does not need to pay for the surplus grain, and every household has something on hand, so they can afford to kill chickens during the New Year.

"No, I still have to take Grandpa up."

"If you ask me, Grandpa should just spend the New Year here. You have so many things to do, take care of yourself first, there are people in the village."

Yang Dazhuang said indifferently, and Uncle Jiu came over and laughed, "Dazhuang is right."

"Just bring him back on the first day of the New Year to kowtow."

"It's enough as long as the intention is there."

Several people persuaded him, but Yang Xiaotao shook his head, "After the New Year, it's just right to take Grandpa to the hospital for a check-up."

"You're old, you have to be careful."

Hearing Yang Xiaotao say this, several people were not in a position to persuade him anymore.

In the early years, Grandpa led a group of old brothers to fight in the flames of war, and those who survived were also covered with scars.

Over the past few years, thanks to Xiaowei's help, his body has barely maintained health.

But time is the most terrifying thing, which can corrode everything in the world.

The only difference is the length of time.

So Yang Xiaotao thought of taking him to the hospital for a check-up after the New Year.

"That's true!"

Uncle Jiu agreed, then thought of something, "By the way, Qiuye, tell me. There are many students coming from the city recently. I'm thinking about recruiting more students to be teachers. There will be more students next year, and there will be more needs."

Uncle Jiu talked about the school for a while. Since Teacher Hong left, the usual trivial matters in the school fell on Uncle Jiu.

Grandpa, the nominal principal, only comes when he is free. As for Ran Qiuye, his focus is now on building the school, so he naturally can't take care of the village school.

"Okay, I'll tell her later."

Yang Xiaotao agreed, and then asked, "Where is Grandpa?"

"Grandpa is still in the greenhouse now."

"You don't know, it has become a treasure for the whole village now."

Yang Shitou smiled aside. "It's warmer inside than the kang at home, and many people sleep in it at night."

"You can watch over the greenhouse at night and protect the greenhouse."

"Really? That's killing two birds with one stone!"

Yang Xiaotao smiled, and then rushed to the greenhouse with Yang Shitou and others.

Came to the south of the village and stood on the river bank.

What caught my eye was a silvery white, closely arranged greenhouses, neatly arranged gray mud walls, and a white film in front reflecting dazzling light, like white waves.

The white was soft, and as the wind blew, this layer of silvery white waves began to sway, and a buzzing sound sounded from time to time, like a sparkling water surface, just like the frozen river water next to it.

Under the greenhouse, clusters of green were reflected, and there were children running and playing hide-and-seek in the middle. In the laughter, adults' scolding came from time to time.

Yang Xiaotao walked down the river bank and quickly disappeared in the silvery white waves.

"I won't go, I'll just spend the New Year here!"

Grandpa Yang was sitting in a greenhouse, his eyes looking at the thermometer hanging on the wood from time to time.

Yang Xiaotao persuaded on the side, and Gao Yufeng also nodded.

"Old Secretary, we are here."

"No, I'm worried! These herbs almost went bad a while ago, we have to watch them carefully."

"We have accepted the task, if we can't complete it, it will delay the national construction, no!"

Grandpa Yang looked up, the green grass in front of him was their task, it was his treasure.

No problem.

Gao Yufeng on the side had nothing to say after hearing this.

In the past, one person was on duty in each greenhouse at night, but near the end of the year, it might be that the weather was very cold, the growth of the herbs was obviously slow, and some greenhouses were sluggish.

This scared them.

The number of people on duty at night also changed from one to two.

And they tried their best to ensure the temperature of the greenhouse.

But in this way, not only do they have to be on duty at night, but they also have to pull the curtains during the day and take care of the herbs in the greenhouse, and the village manpower is not enough.

For these, Yang Xiaotao understood in his heart.

Perhaps part of it was due to the cold weather, but more importantly, Xiaowei, the plug-in, was lost.

Without her help and care, many problems will naturally arise.

But now Xiaowei is back, as long as she is given time, these problems will naturally be solved.

But Yang Xiaotao couldn't say this.

So, after persuading, Yang Xiaotao put the problem on the main contradiction.

Under the watchful eyes of Gao Yufeng and Mr. Yang, Yang Xiaotao walked to the middle of the herbs, then pretended to check them carefully, and picked a leaf with his fingers to observe carefully.

It seemed that he was observing, but it was Xiaowei who was carefully checking beside him.

After watching for a while, Xiaowei explained the situation. Indeed, the energy in the Artemisia argyi in the greenhouse is a little low.

"Master, the energy in this grass is relatively low. I think it should be that the photosynthesis is too weak."

Xiaowei's explanation made Yang Xiaotao understand the current situation.

To put it bluntly, photosynthesis also requires conditions.

In addition to light energy, there must be water and carbon dioxide.

In addition to photosynthesis, there is also respiration.

These two functions complement each other and are indispensable.

Yang Xiaotao understood the situation, so he stood up seriously, walked to the side and picked up the record book in Hou Lijing's hand.

Everyone saw that Yang Xiaotao's face was serious, even Master Yang pursed his lips and did not dare to disturb Yang Xiaotao.

"Are the temperatures here real?"

"Yes, each one is confirmed."

Yang Xiaotao looked at almost the same data and always felt that it was not real.

"Is it the same in other greenhouses?"

Yang Xiaotao looked at Director Gao, and Gao Yufeng nodded, "It's almost the same."

"What, is there a problem?"

Yang Xiaotao nodded, "The temperature difference is not right."

"Why is it wrong?"

"Look, when it was warm before, the temperature was about the same during the day and at night."

"Now it's cold, the outdoor temperature has dropped by three or four degrees, but the temperature inside is the same as before, this won't work!"

"We also have to make appropriate adjustments."

Gao Yufeng and Hou Lijing looked at each other, and Hou Lijing thought for a while and asked, "But the temperature has dropped, will it freeze?"

"No! You have also been to the northwest, it was hot during the day, and you had to wear long sleeves at night. So it is necessary to keep it a little cooler."

Gao Yufeng listened and thought for a while, and finally nodded.

"Listen to Team Leader Yang on this matter!"

Hou Lijing nodded, even if Gao Yufeng didn't say it, she would do what Yang Xiaotao said.

"There's more!"

Yang Xiaotao's face was serious, "It's too tight in here, this won't work!"

"What?"

Yang Taiye didn't know if he didn't hear clearly or felt that Yang Xiaotao's words were wrong, "It's not tight, let it ventilate!"

"It's so cold in there!"

Yang Taiye said puzzledly, but found that Yang Xiaotao was still shaking his head.

He even looked at Gao Yufeng and Hou Lijing, "I just tried it, the soil moisture is OK, there is no lack of water."

"This film is transparent, so it's not a problem."

"But there is another key factor in photosynthesis, that is carbon dioxide."

"You should know it when you were studying."

When Yang Xiaotao told the situation, Gao Yufeng immediately clapped his hands, looking disappointed, "How could I forget this!"

Hou Lijing knew about photosynthesis, but her previous focus was on maintaining temperature, and she forgot about this link.

"I'll let the greenhouse ventilate for a while every day."

Gao Yufeng was very happy to find the problem, and looked at Yang Xiaotao with gratitude, "Thank goodness you're back, otherwise we don't know what it will be like."

"No, I have to tell the dean, it's better to let you stay, you must stay to help!"

Gao Yufeng was a little scared, but also a little relieved.

Fearful that if this continues, what will happen if everything is destroyed?

Luckily Yang Xiaotao is back, the problem was found early and can be corrected.

"Old Gao, you can't repay kindness with enmity!"

Yang Xiaotao heard Gao Yufeng's words. It was so hard to refuse the dean at the Academy of Agricultural Sciences. If this guy brings it up again, it would be repaying kindness with enmity.

"How could it be? I'm responsible for the revolutionary mission!"

Gao Yufeng immediately heard the meaning of Yang Xiaotao's words, and laughed and joked.

"If you want to do this, I'll take the things back!"

"Don't, don't! I'm still hoping to take the things home to celebrate a prosperous New Year!"

Gao Yufeng hurriedly persuaded him. There was no reason to return the things he had obtained.

What's more, Yang Xiaotao gave him meat, eggs and duck eggs, which were the hard dishes on the table during the New Year.

Taking it home would also give him face in front of his wife.

"Just open it for fifteen minutes every day at noon."

Yang Xiaotao suggested, and Gao Yufeng nodded immediately.

And these fifteen minutes are enough for Xiaowei to fly back and forth twice in the farm.

Afterwards, Gao Yufeng and Hou Lijing immediately went out to greet people and give instructions. Mr. Yang on the side could hear every word clearly, but he felt a little confused when he heard it so intensely.

What photosynthesis, what does it mean?

What carbon dioxide, what is that?

I don't understand, I don't understand anything!

But seeing Yang Xiaotao's wise look, he felt very powerful.

The persistence in his heart became irrelevant.

"Will it work like this?"

Grandpa Yang still felt unreal, and asked immediately.

"It will definitely work, you have to believe in science!"

Grandpa Yang opened his mouth, but in the end he had nothing to say.

What the hell is science?

Finally, Grandpa Yang got in the car, waved to Yang Dazhuang, Uncle Jiu and others, and left in the car.

Now, he understood that some things are useless to do blindly.

You still have to let people with ability do it.

"By the way, how is your grandfather's problem solved?"

In the car, Grandpa Yang asked casually with a pipe in his hand.

"It's solved, anyway, the person is fine."

Yang Xiaotao didn't say much, some things didn't happen, and it's useless to talk about them.

However, he also wanted to know, without those two people, how would the course of history change?

"By the way, Master, grandpa asked me to bring this to you!"

Yang Xiaotao took out an iron box from his pocket and handed it over.

"Hey, Lao Jin still remembers it!"

"No, I have been asking him for it before, but he was reluctant to part with it."

Yang Xiaotao looked at the iron box. This was not from the United States, but a wine bottle from Germany.

There are not many of these in the country.

And drinking from this compact wine flask is much more stylish than holding a wine bottle.

I don’t know why I gave it to my grandfather!

Mr. Yang smiled and took the iron box, "When we chatted last time, he said there was such a wine flask. I said I had never seen it before, so he said he had one at home and would give it to me when the time came."

After speaking, he turned his head and took a sip.

"Well, it's a bit like a laojiao!"

In this way, Mr. Yang sipped his mouth all the way, and when it got dark, he returned to the courtyard.
