At the end of the Eastern Han Dynasty, it was said that there were 50 million people in China, of course, there were no families, and the hidden households did not enter the household registration. If you really want to count them together, it is estimated that there may be 70 million.

Let's just say that Mi Zhu was a wealthy local family before he became a businessman, and later married Liu Bei and gave him 2,000 family members. Does his family itself still have 2,000 nominal family members? Or will 2,000 follow-up recruits?

Mi Zhu is like this, those old families, how many families are in the family, thousands, tens of thousands? I really want to make a rebellion, arm the young and strong people in these families, and recruit three or five thousand elite soldiers, or the kind that is not afraid of death.

Based on them, pulling out an army of 350,000 is an easy matter, just like the former Fifth Colonel of the Northern Army. If there is no war, there will be 5,000 troops, and when there is a war, send one or two schools of people over, and when they arrive in the locality, it will immediately expand to 10,000 or 20,000 people.

Since the Yellow Turban Rebellion, not to mention many, millions of people have disappeared, and tens of millions of people have definitely been affected. The only thing that is commendable is that millions of people have fled to Jingzhou, Jiaozhou and Yangzhou, which can be regarded as supplementing the population there.

Even so, there is still a serious shortage to fill up China, let alone fill the prairie and the Western Regions. Liu Tao really wished that he was a child of the fairy family, and he could perform the method of two children a year. Oh, it's triplets or multiples, don't get me wrong.

"Your Majesty, why should you be worried?" Liu Bei didn't understand, what was there to worry about the population problem, "In the current peaceful and prosperous era, not to mention those big families, the people below will work hard to give birth if they have the conditions." A family of two, how can there be five children.

Nowadays, the level of medical care is constantly improving, and the safety of mothers and children can be basically achieved. In addition, there are more means to protect against the cold, and the rate of child mortality in winter has also dropped significantly. Even if only seventy percent survives in the end, within ten years, the population of the entire Han Dynasty will double. ”

Taking into account the factor of holding two in three years, it is indeed possible to double the population base in three years, and if it is more prudent, it will definitely double in five years. Quadrupling in ten years, it's still not a big problem.

Problem: These children are still young, and they have to wait at least ten to twenty years before they can start helping out, that is, they will have to wait at least ten to twenty years before a group of strong men can grow up. Twenty years, God knows where the Han army has gone......

"Let's just say that we have thirteen states in the Han Dynasty, of course, it may be called provinces in the future, and there are more than thirteen. Let's just say that these provinces can accommodate the people, not to mention 1.4 billion, 3.5 billion is certainly not a problem.

The grassland north of Yinshan Mountain is spacious enough to be well developed, and it is not a big problem for two or three hundred million people; Buyeo and Goguryeo, and even with the addition of Samhan, 200 million people are not a problem.

The Great Plains further north, not to mention, are too cold to live there for the time being. 100 million is not a big problem on the Japanese side, and a few million people on the Western Regions side is not a big problem......" Liu Tao simply calculated step by step.

Liu Bei smashed it, smashed his mouth, wanted to say something, but in the end he couldn't say it, why did he think of this step? If you think about it, it makes sense, but the problem is that it's theoretical, how can you know if you don't actually try it?

"Your Majesty, the population has risen so much, what should I do with the food?" Liu Bei had to ask questions.

"Oh yes...... What should I do with food......" Liu Tao was stunned when he heard this, and then he remembered that the consumption of food and various dishes will increase with the increase in population.

The actual situation is not clear, but it can be seen from the management games played before the crossing. When the population increases, the food problem must be solved. There is a very troublesome place in the late stage of this kind of game, that is, the population is increasing, not to mention how to settle the idle population, and this food has also begun to decline rapidly.

In general, it is only possible to increase the area of reclamation and import to obtain food. The people who have settled down need more than just food. They also need vegetables and meat, as well as a variety of non-staple and processed foods.

If you talk about daily necessities, you can leave it to the market to fill it by itself. The problem of grain production is a problem that the state needs to solve.

No sweet potatoes, no pumpkins, no taro, no corn and no potatoes. Farming technology, because of the results of trying to get results in the cloud, has begun to gradually become popular, and the yield has increased by about four or five percent compared with before.

The Champa rice, which crops three times a year, is estimated to be still a weed this year, and even if it is still three crops a year, the yield is not up to standard......

"Xuande, I'm going to bring you a ditch!" Liu Tao suddenly realized something, and directly laughed and scolded, "You patronized and told me about grain, have you forgotten how much arable land we have?" ”

At present, China's cultivated land and occupied territory can be fully supported by 6 or 700 million people. Now there is only a population in Huaxia, and 50 million is estimated to be not enough, so do you need to worry so quickly?

"No, no, no, the minister doesn't dare." Liu Bei hurriedly explained, "It's just that the minister thinks it's better to take precautions." After all, the population is constantly increasing, and in a maximum of forty to a hundred years, we are about to face this problem. ”

It is too cold in the north and the cost of cultivation is high; The western part is all desert, and there is not much area suitable for farming; The south is full of primeval forests, which need to be developed and then cultivated, and that also takes time, and there are terrain environments that are not suitable for farming.

"But Xuande, have you forgotten that I opened an agricultural college. You don't really think that it's all about teaching students how to farm, right? Liu Tao asked rhetorically.

This agricultural college is equipped with a huge botanical garden with plants from all over the world. Spices, food, or wood can be used.

The purpose is also very simple, that is, to study how to improve, how to make the fruit taste better, produce more, and be more delicious.

There are also cereal plantation parks, which specialize in the study of hybrids and improved varieties of various cereals. At the same time, we will study how to improve the technology of improved varieties. This process is recorded and gradually formed into a systematic textbook, which Liu Tao calls biology.

Not just plants, but also various breeds of livestock and poultry. The entire Faculty of Agriculture, just researchers, has more than 300 people, not to mention students. This is not only a school, but also an experimental base.

"This, the minister really doesn't know......" Liu Bei hurriedly confessed, Liu Tao was right, when many people faced this agricultural college, they really thought that this place was to teach people to farm.

Later, I learned that there were still chickens and cattle, and I immediately felt funny, most of the big families did not put their children in. The students here are mainly children from peasant families.

"Don't you know that the College of Agriculture is a subordinate yamen of the Ministry of Industry, and the researchers in it will enter ......the Ministry of Industry to a certain extent," Liu Tao reminded.

There are those in charge of agriculture in the Ministry of Industry, but in fact, they can continue to come out separately in the future. After all, Shangshu Province of Shangshu Province is only called six departments because it was originally divided into six departments. But it doesn't mean that there can only be six in Shangshu Province.

Later dynasties don't know if they have their brains pumped, and they have inherited them one by one, all of which are in these six departments.

It was not until the establishment of the Republic of China and the People's Republic of China that improvements were made on this basis, but this is probably also the result of the influence of Western political systems. At that time, there were still many people who thought that they would break the old society and build a new society.

In fact, I didn't know that I was just improving the system established by my ancestors for a thousand years.
