Become a feudal king from today

"Well, you are making soil fertilizer?"

The indescribable smell made Zhao Xu couldn't help but pinch his nose. ReadМ

At this time, Zhu Tuo remembered that there was still urine simmering in the earthen pot on the stove, and couldn't help but smile.

After King Yan went to Feihu Pass, the students were just memorizing the things in the textbook.

However, after carrying it on their backs, they found that there were many interesting things in the book, and they seemed to be able to make them by themselves.

So they opened up a piece of land in the college.

Then loosen the soil and sow seeds according to the instructions in the textbook.

Then in the next two days when it was time to fertilize, they remembered a soil fertilizer from the textbook.

According to the textbook, this kind of fertilizer can increase the yield per mu.

The method of making it is to heat fifty kilograms of human urine to 20%, put it into an earthen pot and cook it to 10%, mix it with two kilograms of plaster of paris, dry it and then crush it, which is called urea gypsum.

When fertilizing, you only need to apply ten pounds of base fertilizer per acre and five pounds of top dressing in the later stage.

"Yes, Your Highness, I want to give it a try. If this kind of soil fertilizer can increase the yield per mu, it will be a blessing to the people of King Yan." Zhu Tuo said.

In Dasong's current farmland, the yield per mu is only about two dan.

According to the new weights and measures set by King Yan, it is about two hundred and forty kilograms.

As long as this soil and fertilizer can increase the yield by 120 kilograms, it is equivalent to an increase of one-third in the field output of the four counties.

Zhao Xu nodded, and everyone knew about it.

The high productivity of contemporary agriculture relies on two important factors.

The first is chemical fertilizers, and the second is high-yielding seeds.

He is currently unable to cultivate such high-yielding seeds.

Chemical fertilizers are also not as high-end as contemporary ones.

But he can still do it with a little soil fertilizer that can replace chemical fertilizers.

Therefore, he incorporated this urea gypsum into the textbook.

This thing is an alternative method that experts came up with in the early days of the founding of the People's Republic of China when there was no industrial chemical fertilizer.

Among many chemical fertilizers, nitrogen fertilizer is the main fertilizer that promotes yield increase, such as urea.

This urea gypsum is naturally equivalent to a simple urea fertilizer.

But Zhu Tuo and the others obviously used the wrong material.

The plaster was not lime, so he said: "The idea is good, but the material is wrong. This plaster is not lime."

After saying this, all the officials were stunned.

Zhu Tuo's face turned red and he said: "They all have the word "stone" on them, so I thought they were the same thing."

Zhao Xu smiled and shook his head. Gypsum is calcium sulfate, while slaked lime is calcium hydroxide.

But now he can't explain it to the officials.

Then he said: "You put this thing away for a while. After a while, I will find plaster for you."

The reserves of gypsum are very abundant.

In contemporary Xingtai, Hebei, there is a large mine with a capacity of 700 million tons.

Its corresponding location is Liaojun among the four counties.

However, this mine also needs to be found and mined.

"Yes, Your Highness." Zhu Tuo and other students felt a little complicated.

They had been exposed to the smell of urine all morning.

Letting the students put aside the matter of urea-gypsum for the time being, he also randomly selected some students to recite the contents of the textbook.

Then he said to Zhu Tuo: "Although it is better to have no books than to have books, the government should also consider sending these students to the countryside and use what they learned in the textbooks to teach the people how to carry out reasonable farming, animal husbandry, and participate in water power Irrigation projects and the like, simply put, are practices.”

"Your Highness is absolutely right. I will discuss this matter with Prince Liu and give these students the opportunity to participate in government affairs." Zhu Tuo said.

When the students heard this, they all became excited.

They are bored enough by always staying in school.

Moreover, they learned something new and novel, and they wanted to take the opportunity to put it to use.

After staying in the Government Affairs School for a while, Zhao Xu returned to the palace.

Before leaving, he asked Zhu Tuo to call Liu Fu when he went back.

He won't go to the military school. The war has just ended, so Chang Wei and the others probably have a lot of things to do.

As soon as he arrived at the palace, not long after Zhao Xu sat down in the study, Liu Fu came over.

"Your Highness." Liu Fu bowed as he entered the study.

Zhao Xu looked at Liu Fu and said thoughtfully: "I want you to set up a new organization called the Prospecting Department."

"Ore Prospecting Department?" This word is easy to understand. Liu Fu said: "Your Highness, it seems that there is no need to set up a special office for ore prospecting. After all, this is another expense."

Zhao Xu glanced at him and said, "What did you learn in the government school? Farming is the foundation of the world, but mining is the foundation of industry and commerce. There is a huge amount of wealth buried in the land under your feet. Isn't it just a little bit? The expenses are comparable.”

Liu Fu was also aggrieved, "Your Highness, it's not that I don't understand, it's that all the mines that can be found in these four counties have been found, and they are all recorded in the government office."

"I tell you that the current record is only a very small part. What I want is to find everything that can be found." Zhao Xu said, "Stop talking nonsense. The officials of the Prospecting Department will be selected from the outstanding students of the school. After the examination and selection, I will give them some lectures alone.”

"Yes, Your Highness." Liu Fu responded.

He was a little strange, how did King Yan know that there were so many mines underground in the four counties.

The idea flashed through his mind.

In the end, he decided not to think about it. After all, there was only one sentence, King Yan was really unfathomable.

After waving his hand, Zhao Xu asked Liu Fu to go back.

Now that the war is over, it’s time to calm down and engage in development.

After all, the economic base determines the superstructure.

How can I walk for three days and three nights without two steamed buns in my arms?

Thinking of this, he searched hard in his mind.

On paper, all the mineral resources in the contemporary Hebei area, which is now the four counties, were listed.

Moreover, a mineral distribution map was drawn by comparing the contemporary landscape information with the landscape information of the four counties.

After all, although history has changed, some geographical indications have existed since ancient times and cannot disappear or appear out of thin air.

Relying on these geographical indications, it is easier to find the location of these minerals.

After these mines are found, he can use them whenever he needs.

Of course, in addition to the location of the mine, he had to compile a separate teaching material.

This textbook includes the appearance of various types of ores.

It is for the convenience of people looking for minerals.

The teaching materials will be handed over to the people in the Prospecting Department. This is what he told Liu Fu to teach these students specifically.

The next few days.

While he went to the school to explain to the students their doubts, he was drawing a mineral map of the four counties in his study.

Day six.

A group of imperial guards from the capital arrived at the palace.

Also coming with him was a eunuch named Xiao Haizi, who brought Zhao Heng's imperial edict.

After receiving the order, Zhao Xu ordered Feng'er to prepare some gifts for the group.

However, he was rejected by the young eunuch who came.

According to the young eunuch, after Tong San's incident, the palace was closely investigating and they did not dare to mess around.

After handing over the imperial edict, they set out to return.

After the group left, Zhao Xu unfolded the imperial edict.

There are two important messages in Zhao Heng's imperial edict this time.

First, he was allowed to expand the royal army to 150,000 people.

The second one concerns Jinzhou, asking Zhao Xu to provide convenience for Ma Yuan and Mo Kuan.

There is another thing, that is, Yanzhou's 70,000 forbidden troops will be transferred from Yanzhou to Tongguan, so that he and the forbidden troops can complete the handover of the pass.

This incident made Zhao Xu breathe a sigh of relief.

Although he captured Jinzhou, he was still very concerned about who would take over Jinzhou.

If it were anyone else, he would definitely not be happy.

He sacrificed so many soldiers, not to make wedding clothes for Dou Wei and others.

Fortunately, Zhao Heng was not confused and handed over Jinzhou to Ma Yuan and Mo Kuan.

With this civil and military presence, he felt relatively at ease.

After all, the two of them still loved each other.
