As soon as he thought of it, Li Yi went to the printing workshop to explain the principle.

"Proprietor, what about the empty space?" The person in charge of printing then considers the problem that the buckle cannot be stuck.

"Add a wordless mold, and think more about things when you encounter them." Li Yi felt that this person was stupid, said a word, and laughed to himself.

The other party scratched his head: "Isn't it stupid to print so many times a day?" ”

"Now a piece of paper to print? In this way, put a stack of paper, use a glove with rubber to turn the paper, print a sheet and turn it away. ”

Li Yi saw the way of printing, found the problem, and quickly came up with a way to increase efficiency.

Turning he came out, and the people of the workshop were pondering themselves.

As soon as he left the workshop area, Li Yi was slightly stunned.

In front of him, the old man stood there, wearing a new summer dress like the other old men on the Zhuangzi.

A big vest, big trousers, slippers, a fan, and a sweat towel wrapped around his wrist.

"This wood, Uncle wood, you wear this...... Adapted? Li Yi always felt that Old Man Mu was a rich and noble family, and he had to be decent.

"Okay, comfortable, playing chess with them, they wear it, I don't wear it looks different, it's a pity that their Go skills are too poor."

Li Dan shook the fan and said why he changed his clothes, in order to fit in.

"Oh yes, they haven't played Go before, they don't have money, and it's hard to get by."

Li Yi couldn't cry or laugh, and Lao Mu still counted on everyone to play Go.

How long is the next game of Go? The land is not planted? Don't make it up?

Even now, old men and women are not idle all day, they will weave baskets and weave sacks.

When tired, the old man would find someone to play chess, and the old lady would sit together drinking tea and chatting.

"Yes, life is not easy, but there must be a root." Li Dan wanted to change, but he couldn't do it.

"Start with eating and increase the yield per mu." Li Yi said simply.

"If you say it will increase, you will increase?" Li Dan was a little unhappy.

Sinong Temple is not said to be the Tang Dynasty, the former dynasty of the former dynasty...... The agricultural officials are very hard-working.

They know how to tell the people that the seeds of the same crop are planted for more years, and they have to be exchanged with those in other places.

Then the agricultural officer will ask which land in which place has a high yield, and if it is much higher than the next field, they will buy it all and use it as seeds.

The yield of the fields is gradually increasing, but it is still not enough.

As a result, when it came to Li Yi's mouth, he said to increase the output, you add one to me, and I'll take a look.

"This involves a new technology, hybridization, which is grafting." Li Yi put it another way.

Nowadays people will graft, especially fruit trees.

"How is wheat grafted? Break the wheat stalks and replace them with rice ones? "Li Dan actually knows how to graft.

"Uncle Mu, don't worry, it's like this, wheat and rice are male and female by themselves, so that they can have offspring.

If there is one less man, there is no way for the woman. This time look for another kind of rice or wheat, different.

Put the other pollen on the rice and wheat here, and the two will be mixed together.

The resulting child may be a child with both strengths or weaknesses.

Leave the good seeds and plant them again, it may be good drought resistance, or it may be high yield. ”

Li Yi said the hybridization technique, it was easy to say, let him do it......

"Can it be like this?" Li Dan didn't know about it.

"I can look for it, and I observe it during the flowering period, and when I shake it, there is little pollen, or there is no pollen, and the appearance that looks like it is different from the others.

Look at the appearance first, and then look at it with a magnifying glass, I have a magnifying glass in Zhuangzi, and I wanted to discuss it with Sinong Temple.

But this year, I can't do it, I'm busy with the locust plague, next year, next year, I will find wheat and rice from all over Datang.

When looking for it, it is necessary to understand the disadvantages and advantages, and then divide them into pieces and different ones.

When it is time to bloom, go to the plant to carefully search for dead males and pollinate them with other pollen. ”

Li Yi said his plan again, and only after saying it did he react, and he told an old man what was the use of it.

Li Dan didn't feel that he was useless, he said excitedly: "Yes, look for Sinong Temple, let them find it, there are not enough people to ask them to add it." ”

"Okay Uncle Mu, it's hot, don't get excited, know that your family has land, and I hope that the yield per mu will be high." Li Yi was afraid that the other party's qi and blood would rise and fall.

"Yes, my family has land, there is a lot of land, I want to plant, I have to find a way to plant." Li Dan kept nodding.

The first time he heard of this method, it was so strange, and at the same time he felt that it made sense.

"Plant, as long as you find it and succeed, after a few years, it will not be a problem to double the yield per mu."

Li Yi thought about the yield per mu of hybrid seeds he planted with the help of chemical fertilizers and pesticides at that time, and felt that the yield of Datang was indeed too low.

He didn't use pesticides and fertilizers then, which was five or six times better than it is now.

"Double?" Li Dan wants to smoke.

"In a few years, the first generation will continue to be cultivated, and at the same time, the fertilizer will keep up." Li Yi increased the difficulty, don't smoke, I'll have to be busy again.

"That's right, you can't rush, the old man can wait, and the old man will live for many more years."

I don't know that Li Dan, who should hang up next year in history, has to work hard to live.

Although he is no longer the emperor, he is still the emperor, and the people can say that the emperor and the emperor have the grace of heaven and seek the law to benefit the people.

If the grain is doubled, the Tibetans and the Turks will be beaten, and whoever does not accept it will be beaten.

Li Dan's first thought was war, and only with food could it be fought.

Logistics continuously sends food, fighting every day, until the other party has nothing to eat.

"Yes, my uncle is in good health." Li Yi said as he went to a cool place to help Li Dan.

When he got to the shade, he glanced at the green pine standing next to him.

Qingsong immediately ran to get water, sour plum soup.

Li Dan took two sips and showed a cheerful expression: "It's delicious, it's a good thing." ”

Waiting for Li Yi to appease Li Dan and go back to copy the book, Li Dan began to propagate in Zhuangzi.

After listening to this, the farmers didn't care about any details, only knowing that the proprietor said that it was no problem to double the yield per mu.

Last year, the rice and wheat in the Zhuangzi were much higher than others, so do you still need to doubt the proprietor's words?

In the evening, Li Longji, who got off work, came over with Li Chengqi and heard about it......

"Brother Yi, write it down, draw a picture, and write a book for your brother." Li Longji urged, as if he didn't want Li Yi to eat.

"The third brother is not in a hurry, drink, today's dish is good, there are braised pig's trotters." Li Chengqi holds the wine cup.

Queen Wang didn't look like a queen at all, holding a pig's trotter in both hands and nibbling there, nodding there.

"I'm done, I'm done." Li Yi sighed, he found that Old Man Mu was preaching everywhere, and he knew that he had to write.

At dawn on the ninth day of early May, Li Longjixing left in a hurry.

Entering through the back gate, changing his clothes, and waiting for the arrival of his important courtiers, ready for the meeting, he walked easily to his place.

Glancing around, he smiled.

Ministers: "......"

Yao Chong looked at each other and made eye contact: What's wrong with Your Majesty today? Found money? Who did you help Li Yi pit again?

"What's the matter, tell me, I have a good thing when I'm done." Li Longji calmed down.
