Hand over the jade seal first [Infrastructure]

Xiao Zirong's ears twitched when he heard the word "major event". He was a little nervous at first, but when A Yin came in, he found a smile on the other party's face, and asked involuntarily: "What happened so happy?"

How big of a happy event is this for Ah Yin to be so incoherent?

A Yin's excited eyes lit up, and she spoke very fast: "City Master, we found Jiahe in our field!"

Golden Harvest?Xiao Zirong was stunned for a moment, but Liu Cainiang jumped up excitedly and asked, "Really?"

Xiao Zirong immediately searched in his mind, only to find out that the Jiahe mentioned these days is a rice seedling with one body and two ears, and when encountering such rice seedlings in ancient times, they would be picked and dedicated to the ruler to flatter the ruler Yes, it proves that the appearance of auspiciousness is good for the ruler, and the hearts of the people move the heavens.

After Xiao Zirong heard it, he jumped up and asked, "Where is it? Take me to see it now!"

Ah Yin smiled and said: "Aman will bring it later, the weather is too hot, so the city owner doesn't have to make this trip."

After Xiao Zirong heard this, his soul was about to come out of fright, and he said quickly: "Don't, don't, take me there!"

Although Ah Yin didn't understand, she nodded when she saw his serious expression, and led them all the way to her own field.

Along the way, Xiao Zirong was almost flying, and he didn't care about whether it was hot or not, and whether he was sweating or not.

When he ran over, he happened to see Aman gesticulating with a little lady and beckoning her to cut off the rice, Xiao Zirong immediately shouted: "Leave the grain!"

Aman and the little lady were taken aback immediately, so they stopped cutting the ungrown Jiahe.

Xiao Zirong didn't care about the muddy field and ran over to take a closer look at the rice plant with two ears of wheat. After observing carefully for a long time, he was sure that the rice plant was intact now, and he was relieved immediately. .

He felt tired only after he let go of this breath, his legs were so weak that he almost fell directly into the field, but Lu Liu, who ran out after him, reached out and grabbed his collar and dragged him back.

However, Lu Liu's strength was too great, and she didn't know what she had done recently. She felt that her strength was stronger than before, so she picked him up directly by his collar.

Xiao Zirong clutched his neck and hurriedly said, "Let it go!"

Only then did Lu Liu carefully let go of him, and apologized in a low voice.

Xiao Zirong waved his hands, took a breath after tidying up his clothes, and then said to the stunned people around him: "This Jiahe plant is the key to increasing rice production, it cannot be pulled out! Not only can it not be pulled out, but you have to take care of it, When the autumn harvest comes, all the products of this rice will be collected and sent to me."

Xiao Zirong turned his head and said to Liu Cainiang: "Wait and give an order by the way, once Jiahe is found, it must not be pulled out."

Seeing that he was so serious, Aman was a little scared. She almost pulled up the Jiahe tree just now.

Xiao Zirong wiped his sweat to appease the frightened Ayin and Aman. It’s not their fault. Even people who have received relatively advanced education may not know the importance of Jiahe, let alone them. Most people are brainwashed. The more special and difficult things are, the more precious they are. This is the signal from God. Some things are considered auspicious by everyone, while others are considered disasters.

Xiao Zirong took another look at the seedling, took a rest and prepared to go back.

Liu Cainiang followed him and asked, "City Master, is there any other use for this Jiahe?"

Xiao Zirong thought for a while and said, "I'm not sure, I need to go back and think about it."

He knew that in order to increase the yield of rice, he had to use hybrid rice, but in later generations, most people would know that what they ate was hybrid rice, and that the yield per mu of hybrid rice was very high, and there were even rice that could grow in saline-alkali land, but Most people don't know how hybrid rice is hybridized, and Xiao Zirong is no exception.

But fortunately, he still has a library in his head as his theoretical support. Even if he may not be able to produce hybrid rice in a short time, at least he can lay a foundation first, so that no one will see two ears of rice. Just pull it out!

After Xiao Zirong went back, he put aside the unimportant things at hand, and was going to look for literature related to hybrid rice.

In the end, he realized that he had overestimated his abilities. Those documents... He couldn't understand any of them, and the writing on them was very complicated. Even if he found relatively easy-to-understand popular science articles, he was tortured enough.

After reading the whole article, he only knows that hybrid rice is very cumbersome at the beginning. Three-line hybridization, two-line hybridization, and finally one-line hybridization gradually approach maturity. However, even if he knows that the result has no foundation, he must start from scratch. .

Xiao Zirong focused on the three-line hybridization. After reading it, he only knew that he needed three kinds of rice, one is the male sterile line, the other is the male sterile line and the other is the male sterile restorer line. The maintainer line is used The male sterile line is used to propagate the male sterile line, and the male sterile restorer line is used to pollinate the male sterile line to produce hybrid rice seeds that are male sterile and can also have the advantage of hybrid rice.

I have to say that after reading a bunch of documents, Xiao Zirong's mind is full of the word masculinity, and it feels like he almost doesn't know the word.

So now the question is, where can he find male sterile lines, male maintainer lines and male sterile restorer lines?

Xiao Zirong took a closer look and found that there are many ways to produce sterile lines, but the only thing they can use now is to count on natural mutations.

If you want to artificially intervene, you must wait for the science to develop to a certain level, at least after the research on the cell nucleus is possible before artificially inducing intervention.

Xiao Zirong just stayed with Golden Harvest because he glanced at a certain book and knew that Golden Harvest could be used as the basis for increasing production, but he didn't know how to do it.

Now it seems that it is probably because Jiahe itself has coped with the natural mutation, so it probably cannot self-pollinate itself, so it needs normal rice to pollinate it.

The existence of the male maintainer line is to provide a stable male sterile line. If there is a maintainer line, more samples can be used for hybridization experiments, instead of just trying to see if there is Jiahe as it is now.

The emergence of the male maintainer line requires the male sterile line to be hybridized with the normal variety of rice... The good guy has directly formed a closed loop!

When sisters Zhai Xi came over, they happened to see their city lord staring out the window with a tortured look, and couldn't help being startled: "City...City lord?"

Xiao Zirong came back to his senses, wiped his face and asked, "What's wrong?"

Hearing his weak voice, Zhai Xi said cautiously: "That... we have already prepared what you want."

Xiao Zirong suddenly became energetic: "Where is it?"

Zhai Xi and Zhai Ling worked together to move a half-person-high fan in. Xiao Zirong walked over to take a look and found that although the fan was relatively ordinary in appearance, it looked a little plain because it was not painted with varnish, but he had to admit The workmanship of the Zhai family sisters is pretty good, at least in appearance, there is no difference from the drawing on the blueprint.

Xiao Zirong tried to turn the handle. It was a little rough at first, but it soon became smoother. After the fan blades turned, it also brought a cool breeze.

When he stopped his hands and turned his head, he saw the three sisters of the Zhai family looking at him expectantly, and couldn't help laughing: "Your skills are getting better and better."

Zhai Xi was very happy. Before she could say anything, she heard their city lord ask, "How is it? Are these things particularly interesting?"

Zhai Xi looked at him with bright eyes and nodded vigorously, Xiao Zirong smiled slightly: "When you learn all the knowledge from those books, you will make more interesting things."

Sisters of the Zhai family: ...

Never thought that their city lord was waiting for them here, is it really an inescapable study?

Xiao Zirong looked at the three young ladies who were still very excited just now and felt extremely depressed. Oh, no, the ones who were depressed were Zhai Xi and Zhai Ling. Because Zhai Wei was still young, she didn't seem to realize that what was waiting for her was inhumane. learning, still curiously asking: "Really? Can I make more interesting things after learning?"

Xiao Zirong nodded and said: "Of course, and the more you learn, the more you will be able to make new things by yourself. At that time, you don't need me to give you blueprints, and you can make good mechanisms by yourself."

Zhai Wei's eyes lit up in an instant and she said quickly, "Then I want to study!"

Xiao Zirong was very pleased, finally had someone who loves learning, it was not easy.

Zhai Xi and Zhai Ling looked at each other, very helpless, but their city lords never talked nonsense. As people from a family of institutions, even if they did not inherit the core skills of the Mohist family, they still yearned for that gorgeous world.

And strictly speaking, they are not so repulsive to learning. The main reason is that they are not too young, and they are not as good as young girls when they learn calligraphy again. Coupled with their lack of concentration, learning is extraordinarily difficult.

But they also know that Xiao Zirong is doing it for their own good, so... just learn it.

Xiao Zirong on the side didn't know Zhai Xi's change of heart, he was frowning at the fan.

Although this fan is not difficult to use, the problem is that it doesn't seem to be suitable for them here.

Because the hand of the fan is on the back, that is to say, there needs to be a servant to operate the fan, and then the host will blow the air.

Where do they have this condition?Even if there are many people around Xiao Zirong who are willing to do this for him, he will not agree, so changes are imperative.

Xiao Zirong thought about it carefully, then turned around and asked, "Can you move this hand shaker to the front?"

Zhai Xi was stunned for a moment, looked at the structure of the fan, thought for a while and said, "It should be possible, but I'm not sure."

She has never done this before, so it's not good if she doesn't have experience in this field, but since Xiao Zirong made a request, they will naturally try their best to achieve it.

After hearing this, Xiao Zirong waved his hand: "It's okay, just go and toss around casually, don't forget to read the book!"

Zhai Xi left in great pain, but even so, she really changed the fan while studying, so that people can blow the air and shake it by themselves. At the same time, because of the relatively short distance, they even reduced the size of the fan .

Xiao Zirong was very satisfied with this, so he turned around and hung up to prepare to harvest a batch of points.

There is no way, the points issued before always made Xiao Zirong worry that too many would easily cause the treasury's income and expenditure to be unbalanced, so while giving out points to everyone, he tried to get them back.

In order to get back the points, Xiao Zirong even tricked someone to take a piece of ice and put it in front of the fan, and then started to shake the fan. When the wind blows over the ice and then hits the person, it looks very cold, that kind of comfort... ...it would be even better if the fan was electric.

As he thought about it, he quietly put the power facilities on the schedule, but it was just a schedule. There were too many things on his schedule, and it probably wouldn't work in a few years.

Now their focus is to do everything possible to ensure the harvest of the cultivated land.

Fortunately, God was very kind, and there were no major natural disasters until the grain matured.

Soybean matures earlier than rice. Xiao Zirong doesn’t grow too many soybeans. Rao also spread a lot of soybeans on the ground when harvesting. However, these are dried bean vines, and the beans must be broken out with something. just work.

Liu Cainiang looked at Xiao Zirong with his sleeves rolled up and carrying tools, and couldn't help but persuade: "City Master, just leave this kind of thing to them, why do you need to do it yourself?"

Xiao Zirong was very excited and said: "Let's get it done sooner, so I can extract the oil!"

Cainiang Liu: What?
