There were not many things to print, Chu Zhen quickly went upstairs and saw that they were looking around a few bags of things, Lin Daiyu was sitting on the sofa, and clearly said that this was potatoes and sweet potatoes.

"The seeds I ordered have finally arrived."

Chu Zhen said with a smile.

"Arrived?"

Li Qingzhao was quite curious, and pointed to the potatoes, "Can't you buy them in the store?" ”

Chu Langjun can buy a lot of magical things, but seemingly ordinary things can't be bought.

"Our seeds here are specifically produced...... Those that are specially bred can only be planted once, and they can only be eaten when they are planted, and they cannot be kept. ”

"Ahh

When Li Qingzhao and a few people heard this, they only felt that it was incredible, and the grain seeds they bought could only be planted once.

Zhu Yuanzhang asked: "How many meters can you harvest from this acre of land?" ”

"About a thousand pounds."

"A Thousand ......"

Even Lin Daiyu, who is not familiar with farming, was surprised by this number.

"1,000 catties of rice per mu ......"

Li Shimin calculated in his heart, and the expression on his face was wonderful: "As far as I know, one mu of paddy field does not produce more than 300 catties a year, if it can produce 1,000 catties per mu......

I don't know how many people will live!

"Impossible."

Chu Zhen interrupted King Qin's fantasy, "The high yield of our grain here is because of chemical fertilizers and pesticides, you can't make it, at most use fertilizer technology, did the Tang Dynasty have fertilizer?" ”

Li Shimin looked embarrassed, he didn't know much about Nongsang.

Li Qingzhao also looked at it.

Chu Zhen said with a smile: "Manure is also very simple, I will print a copy back for you, it is a modern manure technology." ”

"Thank you, Mr. Chu!"

Li Shimin saluted and thanked him, Zhu Yuanzhang glanced at him and didn't remind him, anyway, it was not bad.

Chu Zhen took out a few books from the box and gave them to them, "This is the planting method they gave me by the way when I bought the seeds, I asked for a few more books, and you can also bring them back." ”

Li Shimin took it, and it was a pity that he couldn't plant it again in September, but Chu Zhen smiled and said that it was no problem to plant potatoes in Chang'an in September, so he was pleasantly surprised.

"It can be planted in September and October, and it can be planted in March and April...... No wonder you say that potatoes can feed millions of people. ”

Zhu Yuanzhang knew too well when it was time to work in the field.

Chu Zhen said with a smile: "Fertilizer is the foundation of agriculture, there is an island on the sea, and there are 100 million tons of guano on the island." Don't underestimate this bird droppings, if you can transport thousands of tons back a year, the grain output will skyrocket. ”

“…… I'll send a ship to sea! ”

Zhu Yuanzhang said through gritted teeth.

Go to sea and dig out guano!

"There are also many such islands on the coast of China, and birds have roosted on them for millions of years, leaving a lot of fertilizer, and the Wa Kingdom later went to rob them. I'll show you the map later. ”

Li Shimin remembered what Chu Zhen said, but he didn't have enough energy to spare, so he could only take these things back first.

After sending him away, Chu Zhen sat back in front of the computer, displayed the satellite map, and asked Zhu Yuanzhang: "What is the situation of sealing my Zhenguo Zhenjun?" ”

"It's the true monarch of the Ming Dynasty who protects the country." Lin Daiyu said with a smile, Chu Zhen looked at her, and she turned her head again.

Li Qingzhao was still sitting next to her.

Zhu Yuanzhang briefly explained the matter, and said proudly: "I am not the king of Qin, so there is no need to hide it." ”

In feudal dynasties, the emperor kept his word, and the founding emperor was even more so.

"I didn't expect you to open the sea ban so simply."

Chu Zhen said with a smile.

He remembered that several emperors after the Ming Dynasty wanted to open the sea, but there were many obstacles, and it was just an order to replace Zhu Yuanzhang.

"You have said the many benefits of opening the sea, am I a stubborn person?"

Zhu Yuanzhang looked at Ryukyu Island on the satellite map, and said: "In the past few days, there have been few letters against the opening of the sea, and only the matter of the sea disaster has been mentioned. ”

Li Qingzhao couldn't help but say: "Officials and gentlemen and doctors do not accept grain, and the powerful officials and rich surnames occupy unlimited land, merge and counterfeit, and are accustomed to customs, and they cannot be banned from being prohibited." ”

Ancient people were really not fools, from the emperor to the magistrate, everyone knew about the problem of land annexation, so there was Wang Anshi's Fangtian Equal Tax Law and Zhang Juzheng's whip law.

Chu Zhen said: "We have a word here, called the Matthew effect. ”

The three of them all looked at him, and Li Qingzhao said, "This word sounds a little strange." ”

“…… Matthew is a word in a Western scripture. ”

Chu Zhen explained: "The specific meaning is that the rich will get richer and richer, and the poor will get poorer and poorer. In layman's terms, the land under heaven will always be occupied by the emperor's relatives, gentry and landlords, unless the land becomes worthless. ”

"How can land not be worthless?" Lin Daiyu asked curiously, her Lin family also bought a lot of land.

"We don't charge agricultural taxes, and we even have subsidies, which means that the country will give you money if you farm."

“……”

Zhu Yuanzhang's face was full of disbelief.

"There is no one and no way to stop land annexation."

Chu Zhen continued: "All the state can do is to collect taxes from those who own land and levy more taxes on the wealthy, so that the poor people will not be forced to rebel because they cannot survive due to excessive taxes and miscellaneous taxes. ”

"Taxation is the foundation of a country, and the matter of money bags cannot be overstated."

Chu Zhen looked at Emperor Hongwu, "The specific measure is to firmly control the tax in the hands of the imperial court, and don't reward salt introductions, mining taxes, tax exemptions, etc., and replace them with money and grain, so as not to fail to collect taxes and lead to a lack of military salaries in the war." ”

When Zhu Yuanzhang heard the salt introduction, he knew that this kid was talking about his policy again, and couldn't help but retort: "I raise a million soldiers, and I won't waste a grain of rice for the people!" ”

"The health center system, right? At the beginning of the Ming Dynasty, it was fine, but it was a pity that in the middle of the period, the fields of the guard post became the private land of officers, and a large number of military households fled, so they could only rely on recruiting soldiers to fight. ”

"It's-"

Zhu Yuanzhang was speechless for a while, where would he have thought that a hundred years later, the system of the guard center that he was proud of would become like this?

Chu Zhen said: "The ruler is long, and the inch is short. If you want to fix everyone's profession and let them inherit their father's business, if you don't want to fight, you insist on letting him go to the battlefield, and if you don't want to study medicine, you can arrange for him to become a doctor, and it's okay for a while, but it's impossible to continue forever. ”

This remark directly poked at Zhu Yuanzhang's household registration system, his face sank, and he immediately retorted:

"What's wrong with the military household? Many people took the initiative to join the army, and I had to order a ban! ”

"That's because now the military households can still divide the land, and when the fields are divided, and then the annexation begins, the military households will start to run away."

Chu Zhen glanced at Zhu Yuanzhang and confirmed that he could still stand it, before he spoke: "Let me ask you, are the sons of the imperial doctor, the grandson, and the great-grandson all imperial doctors?" ”

"The son inherits the father's business."

Zhu Yuanzhang sat there, his face was not good-looking: "I let them specialize in medical skills for generations, can it get worse and worse?" ”

“……”

Chu Zhen could only say: "Emperor Jiajing of the Ming Dynasty was almost strangled to death by the palace maid-"

"What?!"

Zhu Yuanzhang was shocked.

Every time he hears the deeds of those turtles and grandchildren in the Ming Dynasty in later generations, he will always be shocked.

Li Qingzhao touched his neck, the emperor was almost strangled to death?

"Listen to me first, Emperor Jiajing was almost strangled to death, and the imperial doctors didn't dare to save him, but a newly promoted imperial doctor dared, and he was saved with only two pairs of medicines."

“……”

If he could, Zhu Yuanzhang didn't want to listen to the actions of these Ming emperors in later generations.
