Datang first village

【Ask for a monthly ticket】

Regarding Li Yuanxing's suggestion for the credit system, Li Er hastily read it and put it in the list of papers that was handed over to Tianying Pavilion for discussion. Obviously, this matter was not Li Er's concern. .

"Wulang, I received an impeachment for my brother during the summer harvest. It said that you used the grain in the workshop, not eating it, but using it up. Because there is only one impeachment, it is not a big deal. On the contrary, it is Guanzhong. , Henan’s granary is always tight, and my brother is worried that the grain output will be too high, which will cause the grain price in the two places to drop sharply.”

Food, not to mention modern or ancient, is always the most important thing.

Food is the most important thing for the people. Naturally, the most important thing is for the people to eat enough.

Li Erhua Feng turned around: "Wulang, the autumn harvest is coming soon. Jing Zhaoyin's face is blue, and the imperial doctor said that it is because he has not had a good rest for a long time and is tired. Your food in Huazhou, corn is a report. Said that because there is not enough fertilizer, and there is no fine seed, there is only a yield of more than 500 catties."

"It should be enough!" Li Yuanxing didn't seem to understand Li Er's meaning.

Li Er smiled: "Wulang, do you know how many acres of corn are planted in Huazhou?"

"Brother Huang was joking, this matter is still important. Although I was not in Chang'an in the first half of the year, I am still very concerned about the affairs of Huazhou. They are still working hard, although they have not achieved the improvement of hydraulic power and increased the number of fertile fields. According to the requirements of the government, they still planted more than 200 million mu of corn."

"More than 100 million tons is tens of millions of dan. Just one Huazhou is enough to smash the price of Chang'an's grain to a level that my brother can't accept. Tens of millions of dan!"

Li Yuanxing stood up and shook the clothes on his body: "The silk on my body can be better with starch. This corn starch has many uses. For example: textiles, papermaking, food, petroleum, mines, medical treatment, construction , agriculture, forestry, gardening, casting, fodder, and daily necessities can all be obtained.”

"How to use it?" Li Er asked.

"This, let the professionals study it. What Chendi understands is that this starch is very useful for papermaking, textiles, and especially cotton cloth in the future. In the simplest sentence, the qualitative change that can turn copper into gold can make It’s made of super fine paper. Besides, for medicine, starch is a very good mixture. And the soap, to make it really beautiful, still needs some starch.” Li Yuanxing knew a little, but he was not proficient.

Li Er understood: "Brother, I know why someone impeached you for using the food in the workshop."

"There is not enough food to eat, so naturally I dare not use it. But food is originally a raw material for industrial products, and it can be made into food. Corn biscuits are still good. The price of Chang'an City Wine has dropped by five times, because there is enough food and can be made into food." Large-scale industrial brewing."

Li Er was very happy that there was more food.

The summer harvest is in the middle of May in the Tang Dynasty, which is the end of June in later generations.

Li Yuanxing didn't plan to change this calendar matter, and it didn't seem to have a big impact.

When astronomy in the Tang Dynasty develops in the future, people who are proficient in this field will naturally propose changes or suggestions for improving the calendar. It doesn't matter to Li Yuanxing whether to harvest grain in May or harvest grain in June.

As for the autumn harvest, some places have already started harvesting grain in early August.

There has been a telegram from Jiangnan Road that the rice harvest has begun. With the improved planting and simple composting techniques, the yield per mu can reach an average of more than three stones, and the maximum yield per mu is about four stones.

Huainan Road also sent a telegram saying that it is also a bumper harvest year, and in a few days at most, they will start organizing the autumn harvest.

There is no granary pressure in Jiangnan and Huainan, but if it is just rice, such a good year will not make the granary unable to hold it.But Henan Province is different. With Luoyang as the center, the entire Henan Province is planted with corn and sweet potatoes in autumn. They are expected to be harvested around August [-]th.

The quantity... Huge!

But with such a huge amount, Li Yuanxing still thinks it is not enough.

"Brother Huang, it seems that there is enough food in Guanzhong right now, but what about the next five years?"

Li Er left the desk and sat next to Li Yuanxing: "Wu Lang, you continue to talk. What will happen in the next five years?"

"Brother Huang, first calculate the population. There are three accounts to be calculated for the population."

Li Er, who had just sat on the chair next to Li Yuanxing, stood up again, returned to the desk, and opened a piece of paper: "Wu Lang, go ahead and say, you claim to be bad at math, but your ability to calculate accounts is not ordinary."

Li Yuanxing smiled and stood in front of the desk.

"Brother Huang, the first sum is naturally the population growth rate. In fact, it is the number of people at the end of the year minus the number of people at the beginning of the year, and then divided by the average annual population. If this index is zero, it means that the population has not increased. Of course, we don’t need to make too complicated calculations and announcements, we use the simplest algorithm, which is how many children a woman will have, and how many children will be born in a household.”

When it comes to public announcement, Li Yuanxing is afraid that he will not explain clearly to Li Er.

As for Li Er, he doesn't want complicated formulas either, all he wants is numbers.

"Brother Huang, if there are couples of the right age in the Tang Dynasty in the past five years. According to the statement of the younger brother who gave birth to a child, the tax will be reduced. The average household in the Tang Dynasty will have three children in the past five years!"

Hearing Li Yuanxing's calculation, Li Er shook his head.

"Goro, you have underestimated the tax reduction policy for having children. According to the current situation in Datang, a family of the right age has an average of one male, two quarters and three quarters of females. Of course, if maids and maids are added, the figure will be different." It's even bigger. You have to know, during the war at the end of the Sui Dynasty and the forced conscription of soldiers, how many men died?"

"Then the emperor said how many children will be born?"

"A family of five is at least five years. In five years, Datang can add tens of millions of newborn children. As long as you, Goro, dare to say that you have more babies, you will reduce taxes, or even exempt them. This number of population increase will definitely exceed Goro. Imagine. You know, ordinary people don't have that much fun, what else can they do at night?"

After Li Er said this, Li Yuanxing felt a little scared.

"Brother Huang, according to what you said. The matter of tax cuts has to be reconsidered. I feel a little guilty. With a population of 1000 million, each person is one catty a day, and each person is four loads a year. The grain needs to be at least 4000 million dan.”

Li Er wrote down on the paper: "4000 million is not enough, a catty a day is really not much!"

Li Yuanxing let this one go: "Brother Huang, the second book is foreign nationalities, and they don't grow food. When they belonged to the Tang Dynasty, what they provided was combat power, industrial products, and labor. But the grain Items need to be paid by the Tang Dynasty. Take the Khitan people as an example, their total population is a huge number, and adults eat a lot!"

"The Khitan people eat meat. Pigs, cattle, sheep, etc. consume food!"

Li Er also said something in agreement.

"Also, Datang's dolls are exempt from tax, can we not exempt them?"

Good guy, it's not like I don't know, it's a shock.

The pen in Li Yuanxing's hand did not write a word on the paper, because the account was no longer easy to calculate.

In addition to Khitan, there are Mohe people and Shiwei people.

Although they are taught to farm, the food they grow is not enough for themselves.Still relying on military exploits to get more food from Datang, if the population is not restricted, their food consumption will be even greater in the future.

"Brother Huang, this third account is even more scary. Datang is now industrialized, and many people have seen that working earns more than farming. In the future, the number of people farming will definitely decrease, and the number of people working will definitely increase. Then, Brother Huang, this contradiction is terrible. Besides, when we occupy land, the newly occupied land will have a negative amount of food for at least two years, and a lot of it!"

Li Er began to look through the pile of seals.

He quickly found a seal: "Xiao Yu's, you should have also copied your Qin Palace. It's just that you are fighting outside, so you may not know about it."

Li Yuanxing turned over the watch and saw that it was the third item he said.

Just for the places in Goguryeo that are currently occupied, Xiao Yu calculated that at least 2000 million dans of grain are needed every year to barely meet the needs.Because the Goguryeo people can really feed themselves by growing grain, it will take at least another three years for the new grain fields in Jian'an city to feed the garrison in Jian'an next year.

It's just the garrison, and I'm afraid they will be nervous if they want to transfer some food to the surrounding mining areas.

"How many acres of land per person?" Li Yuanxing asked a seemingly irrelevant topic.

Li Er didn't answer right away, he was recalling the records of the Ministry of Households that he had read, and there was data on the land of the whole country during the summer harvest.About 260 million dumps.

"One person has ten acres!" Li Er was not sure if the data was correct.

Li Yuanxing leaned over Li Er's desk and began to draw on Li Er's piece of paper: "Brother Huang, you can't tell me how many fields there are in the Tang Dynasty, and neither can you. It was handed over by the Ministry of Household Affairs. The data is just the data from the newspapers of various states and counties, which is not very accurate, and there are quite a few differences."

"Well, I knew about this matter when I was a brother in the Wude period, but I never had the opportunity to get it right!"

"Brother Huang, in the Great Qin Dynasty, the land was only so big, with a population of 500 million. At that time, Arita was about eight acres per person. When the Western Han Dynasty was the strongest, the population exceeded 5000 million, and at its peak it exceeded 6000 million. Seven and a half mu per person. At the end of the Eastern Han Dynasty, it was eleven mu.”

What Li Yuanxing said, Li Er would not doubt it, if he needed to confirm it, he would just check the historical materials.

"My Datang, now has 360 million households, which is almost 300 million people. But we have less than 5000 million mu of good land, and the yield of the rest of the bad land is too low!"

How low is the yield of bad fields, on average, it is less than one stone, only eight and a half!

"Brother Huang, one person has five acres of good land. Let's not talk about the number of acres, let's talk about how much food a person has. It doesn't count Chang'an and Luoyang. According to the average yield of two hundred catties per mu in the Tang Dynasty, each person only has one thousand a year. I’m afraid that my younger brother won’t know, but I’m afraid! If I don’t do anything now, I’m afraid my younger brother will be powerless in three years’ time!”

What is Li Yuanxing afraid of?

Li Er knew without explaining that Datang is developing now, but if the food does not keep up with the development, there may be turmoil and the country will be unstable.Datang is now not only consumed by the people of Datang, but also has a lot of external consumption, which will increase the pressure on Datang's food.

"Brother Emperor, I invite Tianying Pavilion to discuss matters." (To be continued.)
