The farm has a phoenix

Chapter 257
Tidying up and washing, washing away the wind and dust all over her body, when she finished tidying up and sat on the small couch drinking tea in only her unlined clothes, the hot dishes had already been set, Chen Shaoyan lifted the curtain of the inner room, her black hair was loose and blown down from her neck, His dark eyes were half-opened, exuding a bit of laziness. He leaned against the door frame, looked at her and chuckled: "Eat something."

She responded, and followed him to the outside room, the food is not much, the price is exquisite, Nuanyu and Huancui are not there, a pot of wine is warmed on the table, the husband and wife have a light drink.

The longing for nearly two months reached its strongest at this moment, the two of them had an early rest, and when they saw the lights outside Huancui had gone out, they covered their mouths and sniggered, and took Nuanyu away.

The next morning, I continued to get up early and went to court. The emperor wanted to personally recruit river diggers. Naturally, he was opposed by many people, including Bai Yulian.

So it can only be discussed later, and the digging of the river will be delayed.

After the imperial court, Zhan Jinfeng went to the Department of Agricultural Affairs School. This class went very well. Many people followed Dabai to Mianqi Villa for practice. Many people have been able to make a good greenhouse alone. .

Ye Laogui was also very satisfied with this, and from time to time he asked Chen You'an to have fun, telling him how good his students were.

Chen You'an smiled slightly, and refused to comment. Ye Laogui was making fun of himself, and after a long time, he stopped mentioning it.

Zhan Jinfeng decided to give another class and let herself explain it. Once this was mentioned, even Zheng Weishuang was surprised.

He hadn't even heard what Zhan Jinfeng was going to talk about. What was it called pollination?
"Master Zhan."

Zheng Weishuang bowed his hands, and now Zhan Jinfeng is a third rank, one rank higher than his official position.

"Even we haven't heard of this thing, can you ask adults to teach us too?"

Zhan Jinfeng nodded readily and agreed: "Okay, I also hope to have a few more teachers, so that I can relax more."

Zheng Weishuang was very happy when he heard the words, so he began to work in the Department of Agricultural Affairs. First, he led everyone to study internally, so as to save time for the class to start. Don't let anyone come in and ask.

Zhan Jinfeng took one hour a day to teach everyone a biology class.

Let's start with the structure of the flower.

The receptacle and calyx, just now the north is also warm to drink, the spring is warm, and the flowers are blooming. Pick some flowers at random, and then she can explain them to these people. Then she talked about the male and female of the flowers. She was afraid that everyone would not understand, so she beat a boar. Take the example of a sow. At this time, these talents suddenly realized that the flowers that only bloom but do not bear fruit are male flowers, which is why there are many blooms but the yield cannot increase.

"But there are exceptions to this."

Zhan Jinfeng patted the "small blackboard", which was invented by Zhao Hongyu. It was not a blackboard, but a board erected with a thick layer of rice paper on it.

It is because of this thing that the gentlemen in the school can write on it, and then everyone in the classroom can see it.

Zhan Jinfeng couldn't help giving Zhao Hongyu a thumbs up. This thing is indeed very well made, but it would be more convenient if it was painted with pot bottom ash and white powder for writing. That's the most important thing.

"Most of the flowers are monoecious, which means they live together as husband and wife and can be fertilized at any time..."

People at this time don't even know what a fertilized egg is, so when Zhan Jinfeng told them this, they couldn't understand the hidden meaning in it, they still listened carefully, and wrote down carefully with a brush in a small notebook Fertilized eggs a few words.

Flowers are fertilized in many ways, wind.Insects, birds, including artificial insemination and so on and so forth.

While Zhan Jinfeng was talking, he took out the peach tree branch that was broken off from Mianqi Villa today, and gave a demonstration to these people.

The structure of the petals has already been explained, so she only needs to tell everyone that it is enough to let the pollen fall on the stigma, and she demonstrates it gently, and then shows it to everyone, so that everyone understands what pollination is.

Zhao Hongyu listened very carefully, until after he finished listening, he suddenly raised his head and asked, "Then when people in the south raise bees, the fruit trees often grow fruitful in the places they pass by. Is it because of this relationship?"

"Yes!" Zhan Jinfeng nodded with a smile. Although Zhao Hongyu is young, she is very observant and likes to chat with others. Naturally, she can inquire about many rumors from many sources, and this one is very useful.

Hearing this, even Zheng Weishuang couldn't help being surprised: "Does that mean that as long as we keep bees, we will have a good harvest?"

Zhan Jinfeng smiled slightly. Although Zheng Weishuang was quite old among these people, his way of thinking was still as flexible, not losing to young people at all.

Zhan Jinfeng smiled and replied cautiously: "Theoretically, that's right."

"What is theory?" Zheng Weishuang asked persistently.

Zhan Jinfeng also patiently answered one by one: "Because we can't control the consciousness of bees, they won't pick all the honey from every flower as we think, and then pollinate. It may be missed, or It is attracted by other flowers and picks other types of nectar, then the pollination process will be greatly reduced, and the percentage will not be [-]%."

Zheng Weishuang lowered his head.

"Then artificial pollination is better." Gao Wei, who had been silent all the time, asked meticulously with a straight face.

"In theory, that's right."

Hearing this, Gao Wei also frowned: "Why is it theoretical?"

"Because of artificial pollination, the process will inevitably cause damage to trees or petals, and if it is an orchard of more than ten acres, wouldn't it mean that the pollination has not been completed after the flowers have finished blooming?"

Hearing this, everyone couldn't help but whispered to each other.

Zhan Jinfeng hesitated for a while. It is a good thing to be serious, but it is more troublesome to care about pollination so seriously. No matter what, it is difficult to be perfect, and there will always be fish that slip through the net.

Seeing everyone whispering and discussing endlessly, she had no choice but to stop it: "Everyone be quiet, let me explain to everyone."

Then the officials of the Department of Agricultural Affairs, ranging from those in Gaowei who are in their 70s and [-]s, down to those in their early twenties like Zhao Hongyu, all of them turned their attention to Zhan Jinfeng, and Zhan Jinfeng couldn't help feeling a wave of ecstasy.

I have given lectures to people before, but this is the first time I have given lectures to people in state government agencies like this, and I still feel a sense of accomplishment.

She had no choice but to give a general introduction to the problem of probability, and then... the trouble was big...

"What is this? Probability? How do you calculate it? Come on, tell me!" Gao Wei stood up excitedly, his beard trembling.

Seeing this, everyone burst into laughter: "Master Gao, don't frighten his little wife."

Gao Wei blushed, and then remembered that Zhan Jinfeng was still a woman, so she could only sit down with a muffled groan, but she still couldn't help asking her, "How is this calculated?"

"Master Zhan, Mr. Gao likes mathematics very much. If it is not because he wants to do more for the common people, I am afraid he will go to the yamen of the abacus!"

Everyone laughed, and Zhao Hongyu couldn't help asking: "Master Zhan, please tell us about this, I think this thing is also useful in agriculture, for example, we can calculate the probability of a good harvest this year, and the weather probability of the situation."

After hearing this, everyone stopped laughing, and all of them looked at Zhan Jinfeng seriously.

She only thinks that one head is two big, and she simply knows about probability and remembers the formula, but he has no way to explain the specific content! ! !

But seeing everyone's expecting eyes, she decided to simply talk, and they left the rest to their free play.

I don’t know if the person who invented probability will be pissed off by himself, forget it, let him go, it’s best if this thing can appear in China, at least we are ahead.

Zhan Jinfeng grinned, wrote down a series of formulas on the small blackboard, and explained them slowly.

Therefore, the one-hour class every day was full of seats. Even if they had something to do, these officials insisted on coming every day. Even the emperor asked them to go to various places for inspections. Chun Yuyue was very curious, what was this little girl talking about so that these old stubborn people could listen to it with interest?
Thinking of the end, Chunyuyue still felt very curious, so he had someone call Zhan Jinfeng to the upper study.

This little girl will always give him many surprises, one after another.

After learning from Wang Gonggong why the emperor asked him to come here, Zhan Jinfeng had an idea in his mind. It was still early in the morning, and the upper study room was brightly lit, so Chunyu Yue bowed his head to the writing table and concentrated on reviewing the memorial.

Chun Yuyue was indeed a good emperor, more diligent than the inactive prince and the treacherous fourth prince.

"See the emperor." Zhan Jinfeng bowed cautiously.

Chunyuyue raised his head and glanced at her: "I heard that your Department of Agricultural Affairs is also having a class to study. Why don't you tell me what you're talking about."

Zhan Jinfeng answered yes, and told Chunyuyue the structure of petals and pollination that he had told Zhao Hongyu and the others. After the lecture, Chunyuyue was very interested and asked many questions. Zhan Jinfeng only answered simple answers. It's rare, but it's a deliberate trick.

"Your Majesty, does Your Majesty think that the enemies on the surface are more frustrating, or the enemies in the dark are more frustrating?"

Chunyu Yue, who was deep in thought, froze for a moment, and looked up at her.

He thought for a while: "Of course it's on the bright side, after all, I can see their every move."

As he spoke, he looked up at Zhan Jinfeng: "You suddenly changed the subject, what exactly are you trying to say?"

what you want to say?Naturally, it is her own Mianqi Villa, she needs that piece of orchard.
