Scholars in the courtyard.

Chapter 1658 Science, what is it?

Yangjiazhuang.

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

The car stopped in front of the brigade office, and as soon as we got off the car, we could feel the strong festive atmosphere.

"You came back at a good time, as they are slaughtering chickens at home. Don't leave tonight."

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

These days people say a chicken's butt is a bank and an old lady is the president.

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

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

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

Of course, rare does not mean non-existent.

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

Because of its status as a farm, Yangjiazhuang seems like an independent entity in this world.

Apart from completing the breeding work required by superiors, production income does not need to be handed over.

That is to say, Yangjiazhuang did not need to pay surplus grain to the government, and every household had something on hand, so they could afford to kill chickens during the New Year.

"No, I still have to take my grandfather upstairs."

"If you ask me, Grandpa, just spend the New Year here. You should take care of your own things first. There are still people in the village."

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

"When the first day of the new year comes, just bring him back and kowtow to him."

"It's enough if the intention is there."

Several people tried to persuade him, but Yang Xiaotao shook his head and said, "After the Chinese New Year, it's a good time to take Grandpa to the hospital for a checkup."

"When you get older, you have to be more careful."

After hearing what Yang Xiaotao said, they were not in a position to persuade him any further.

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

Over the past few years, thanks to Xiaowei's help and care, I have managed to maintain good health.

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

The only difference is the length of time.

That's why Yang Xiaotao thought of taking him to the hospital for a check-up after the New Year.

"makes sense!"

Uncle Jiu agreed, then thought of something, "By the way, Qiuye, tell me. There are quite a few students coming to the city recently, and I'm thinking of recruiting more students to be teachers. There will be more students next year, and we'll need more."

Uncle Jiu talked about school matters for a while. Since Teacher Hong left, the daily chores of the school fell on Uncle Jiu.

The grandfather, the nominal principal, only comes when he is free. As for Ran Qiuye, his focus is now on building the school, so he naturally cannot take care of the village school.

"Okay, I'll tell her later."

Yang Xiaotao responded, then asked, "Where's the master?"

"Grandpa is still in the greenhouse."

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

Yang Shitou smiled at the side. "It's warmer inside than at home. Many people sleep inside at night."

"I can both watch over the greenhouse at night and protect it."

"Really? That would be killing two birds with one stone!"

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

Come to the south of the village and stand on the river bank.

What catches the eye is a silvery-white expanse of closely-arranged greenhouses, neatly-arranged grey mud walls, and a white film in front reflecting dazzling light, like white waves.

The white color is soft, and as the wind blows, this layer of silver waves begins to sway, and a buzzing sound can be heard from time to time, like rippling water, just like the frozen river water next to it.

Under the greenhouse, clusters of green are reflected, and there are children running and playing hide-and-seek in the middle. Amid their laughter, scoldings from adults can be heard from time to time.

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

"I'm not going. I'll just spend the New Year here!"

Grandpa Yang was sitting in a shed, his eyes constantly fixed on the thermometer hanging on the wood.

Yang Xiaotao persuaded him and Gao Yufeng nodded.

"Old Secretary, we are here to serve you."

"No, I'm worried! These herbs almost went bad a while ago, so I have to keep an eye on them carefully."

"We have accepted the mission. If we fail to complete it, it will delay the country's construction. No way!"

Grandpa Yang looked up. The green grass in front of him was their mission and his treasure.

There can't be any problems.

Gao Yufeng, who was standing by, had nothing to say after hearing this.

In the past, there was one person on duty in each greenhouse at night, but as the year drew to a close, perhaps because the weather was very cold, the growth of the herbs was noticeably slow, and some greenhouses even showed signs of sluggishness.

This gave them a fright.

The number of people on night duty increased from one to two.

And we do our best to ensure the temperature of the greenhouse.

But this means that not only do they have to stand guard at night, but they also have to pull the curtains during the day and take care of the herbs in the greenhouse, so there won’t be enough manpower in the village.

Yang Xiaotao understood all this.

Maybe part of it is because of the cold weather, but more of it is because of the loss of Xiaowei as a plug-in.

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

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

But Yang Xiaotao couldn't say anything about this.

So, after some persuasion, Yang Xiaotao focused on the main point of contradiction.

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

It looked like she was observing, but it was actually Xiao Wei who was examining carefully.

After watching for a while, Xiaowei explained the situation. Indeed, the Artemisia selengensis in the greenhouse had less energy in its body.

"Master, there is relatively little energy in this grass. I think it is because the photosynthesis is too weak."

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

To put it bluntly, photosynthesis also requires conditions.

In addition to light energy, it also requires 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, and then 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, and even Mr. Yang pursed his lips and did not dare to disturb Yang Xiaotao.

“Is the temperature here real?”

“Yes, every one of them is confirmed.”

Yang Xiaotao looked at the almost identical 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 always like this."

"What, is there a problem?"

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

"What's wrong?"

"You see, in the past, when the weather was warm, the day and night were almost the same."

"It's cold now, the temperature outside has dropped by three or four degrees, but the temperature inside is the same as before. This won't work!"

"We also need to make appropriate adjustments."

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

"No! You've been to the northwest before. It's so hot during the day and you have to wear long sleeves at night. So it's necessary to keep it a little cool."

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

"We'll listen to Team Leader Yang on this matter!"

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

"besides!"

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

"What?"

Mr. Yang didn't know whether he didn't hear clearly or felt that Yang Xiaotao's words were not right, "This is not tight, it's leaking!"

"It's not cold in there!"

Master Yang said this in confusion, but found that Yang Xiaotao was still shaking his head.

He even looked at Gao Yufeng and Hou Lijing and said, "I just tested it. The soil moisture is OK. There is no lack of water."

"This film is light-transmissive, so that's not a problem."

"But there's another key ingredient in photosynthesis, and that's carbon dioxide."

“You should have known this when you were studying.”

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

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

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

Gao Yufeng was very happy to have found the problem, and looked at Yang Xiaotao with gratitude, "It's a good thing you're back, otherwise we don't know what would have happened."

"No, I have to talk to the dean. It's better for you to stay. You must stay and help!"

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

I'm afraid if this continues and everything gets ruined, how will I explain it?

Fortunately, Yang Xiaotao is back and the problem was discovered early and can be corrected.

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

When Yang Xiaotao heard what Gao Yufeng said, he had finally rejected the dean at the Academy of Agricultural Sciences. If this guy brought it up again, it would be like repaying a kindness with a hateful heart.

"How could that be? I am fulfilling my revolutionary mission!"

Gao Yufeng immediately understood the meaning of Yang Xiaotao's words and even laughed and joked.

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

"No, no! I was hoping to take some home and have a good year!"

Gao Yufeng hurriedly persuaded them that there was no point in returning something they had already obtained.

What's more, Yang Xiaotao gave meat, eggs and duck eggs, which are the main dishes on the table during the Chinese New Year.

Take it home and you will feel proud in front of your wife.

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

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 call people and give instructions. Master Yang who was standing by could hear every word clearly, but when it came together so intensely, he felt a little confused.

What is photosynthesis and what does it mean?
What is carbon dioxide? What is that?
I don’t understand, I don’t understand anything!
But seeing Yang Xiaotao's wise look, I felt he was very powerful.

The little bit of persistence in my heart no longer matters.

"Is this how it will work?"

Master Yang still felt it was unreal, so he asked.

"It will definitely work. You have to believe in science!"

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

Science, what the hell is that?
Finally, Grandpa Yang got in the car, waved to Yang Dazhuang, Uncle Jiu and others, and drove away.

Now, he realized that it was useless to just blindly do some things.

We still have to let capable people do it.

"By the way, how is the matter with your grandpa going?"

In the car, Master Yang was smoking his pipe and asking as if nothing had happened.

"It's solved. At least the person is fine."

Yang Xiaotao didn't say much. Some things didn't happen, so there was no point in talking about them.

However, he also wanted to know how the course of history would change without those two people.
"Oh, by the way, 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!"

"That's right. I kept asking him for it, but he was reluctant to give it to me."

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

There are not many of these things in the country.

Moreover, drinking from this small wine jug is much more stylish than drinking from a wine bottle.

I don’t know why I gave it to my grandfather!
Grandpa Yang took the iron box with a smile, "Last time we were chatting, he mentioned this kind of wine pot. I said I had never seen one, and he said he had one at home and would give it to me when the time comes."

After saying that, he turned his head and took a sip.

"Well, it looks a bit like an old cellar!"

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