After writing, Lu Bu said in a serious voice: "First of all, I want you to know what the three major industries are. The primary industry mainly refers to the industry that produces food ingredients and other raw materials. There are mainly planting, forestry, animal husbandry, aquaculture and so on. ”

"The secondary industry refers to the processing and manufacturing industry, which is mainly the use of the primary industry and the original materials in nature for processing, commonly known as industry."

"The tertiary industry refers to all industries except the primary and secondary industries."

As soon as the three major industries are mentioned, everyone in the audience is in a state of confusion.

Lu Bu sighed and continued: "I don't force you to fully understand as soon as you come, I will explain to you slowly. And your main learning during this time is the primary industry. ……”

Lu Bu gave various explanations, and he was not prepared to let the people below ask questions, which would hinder the rhythm of his lectures.

As Lu Bu continued to explain, everyone's expressions finally became colorful.

Some people suddenly realized and kept bowing their jaws.

Some people frowned, as if they were understanding some kind of truth.

Some people are still confused, still unable to understand.

Every time Lu Bu finished a lecture, he would stop and ask questions. Then give answers and solve everyone's doubts.

Undoubtedly, such an effect is very obvious.

The people present are all adults, and it is no problem to be literate and literate. This knowledge is not difficult, and it can be understood with a little explanation.

The next day.

"What we want to talk about today is also the most important planting industry, and everyone has to listen to it well!"

As soon as Lu Bu said this, a group of people obediently took out paper and pencil and took notes.

On this day, Lu Bu mainly explained how to plant.

His policy for everyone was to grow rice, that is, rice, in all paddy fields. If the water source is insufficient, grow corn, that is, millet. As for the dry land, it is all used to grow wheat, soybeans and other crops.

In this era, water conservancy was too backward, there were too few paddy fields, and it was difficult to grow rice, so Lu Bu could only arrange it for the time being.

As soon as Lu Bu's resolution came out, he was naturally strongly questioned by everyone present. They understand soybeans and can grind them into tofu, but why should wheat be grown in large quantities.

Because the wheat rice is too unpalatable in the eyes of everyone. Although the yield of wheat is higher than that of corn, it is basically not planted in the field, and it is used as a transition when the crop is not cropped. Because of this thing, even livestock don't like to eat it, let alone people.

Of course, most of the people present were children of the family, and they had never eaten wheat rice if they had never been hungry.

Although they had never eaten it, they had heard of it, so they naturally knew that the wheat rice was unpalatable.

Lu Bu thought to himself, the wheat was directly steamed and eaten, and even some shells were not removed, so it was strange that it was delicious.

Of course, they can't be blamed, there is no flour grinder, how can they understand the word flour.

When Lu Bu said the steamed buns that everyone ate yesterday, everyone present was shocked.

Such a delicious steamed bun turned out to be made of wheat.

When Lu Buyi explained, everyone present finally fully understood what the secondary industry was.

And everyone had eaten that delicious steamed bun yesterday, so they naturally understood the importance of wheat. In this way, it is definitely a big special.

Because the land is basically grown now, corn is more drought-tolerant. There are too few paddy fields, but there are many dry lands, so it can be said that there are too many.

If you plant all the wheat, are you still afraid that there will be no food to eat, and will anyone starve!

Many people have secretly made good intentions, and when they go back, they must vigorously reclaim wasteland and grow wheat.

This is a huge benefit, and no one will ignore it.

Although many people are still thinking about their families, it has a huge role in promoting a prosperous society.

People who are wealthy and powerful are also people.

It is also impossible for Lu Bu to demand equality for all, which is absolutely impossible in this era.

If he fights against the family and Haoqiang now, he will definitely die.

The previous rebellion of Chen Deng's father and son is a living example.

In fact, he himself was a strong proponent of the hierarchical system.

Survival of the fittest, the law of the jungle, is the principle he believes in. If you want to become a human being, then work hard. He's just going to create an opportunity for everyone to climb up.

He also has no reason to fight for the weak with pure quenching.

Lu Bu was born in the countryside, and when he was a child, he also cultivated some land, so he knew a lot about agriculture.

Therefore, Lu Bu explained how to develop water conservancy and use ditches to store and irrigate paddy fields. He will build windmills in the future, and carrying water will not be a problem at all.

And how to use human and animal manure with grass ash centralized fertilization and other concepts.

You know, this world doesn't know anything about farming except for a fire.

I don't care about planting it, just waiting for the autumn harvest.

I don't know how to weed, I don't know how to work intensively.

With this kind of farming, even if you are specially given hybrid rice, you will not be able to grow a thousand catties per mu.

It's a pity that Lu Bu is the first to speak. But these children of the family don't understand agriculture, and there are too few people who understand it.

Lu Bu didn't force it, he just wanted everyone to remember what he said and guide the work according to what he said.

In addition to growing grain, of course, we must not forget important products such as mulberry and hemp.

The planting industry is too extensive, and Lu Bu talked about it for two days.

On the fourth day, Lu Bu talked about animal husbandry.

This is also a top priority, and Lu Bu issued a strict order on the spot. For one year, chickens and ducks are not allowed to be eaten.

Well, that is, eggs and duck eggs, all chicken and duck eggs, all take them to hatch eggs.

Although there is little grain now, it is difficult to breed in large quantities, but Lu Bu has done research, and now the population has decreased sharply, as long as more natural resources are used, there is no need for too much grain in the early stage.

In short, I must be given compulsory breeding.

In particular, ducks can basically be fed where there is water, so they must be focused on. Ducks grow fast and their economic value is huge.

Now that there is no cotton, he can use duck feathers to make down jackets and duvets. It's a pity that people in this era don't know how to take advantage of it at all.

Moreover, it is naturally pigs, and the pig industry in this era is relatively developed. It's a pity that with the war, people can't feed themselves, how can they raise pigs.

Therefore, Lu Bu was not too demanding, and he could only raise it with sake lees and other things in the early stage.

But everyone must try their best to develop animal husbandry, and Lu Bu's goal is to have one meal of meat per month for everyone within half a year.

Within a year, each person can eat one meal of meat in three days.

For two years, everyone will be able to eat meat every day.

Within three years, everyone will be able to eat chicken, duck and fish as much as they want.

After hearing Lu Bu's grand goal, everyone present was moved.

Such an ambitious goal is unprecedented.

Neither Emperor Qin nor Emperor Wu of Han could do this.

But everyone present believed that Lu Bu could do it.

No one will object, because they also want to enjoy a good life!

Now everyone understands where the materials come from, and for their own enjoyment, they must develop well.

Because they have always been at the top of the human race, they are naturally the first to enjoy it.

Next, Lu Bu also gave a general explanation of some processing and manufacturing industries.

Lu Bu, who was too profound, didn't dare to talk about it, and everyone couldn't understand it.

He can only talk about existing things, such as duck feathers and mulberry linen into clothes, grain into wine, trees and grass residues into paper.

However, the premise for developing the secondary industry is that we must vigorously develop the primary industry.

At the same time, the secondary industry will also promote the primary industry, and eventually the endless tertiary industry will be derived.

In short, after returning to the local authorities, they must do their best to tap the resources of various localities.

If it is suitable for planting, it will be vigorously developed, and if it is suitable for breeding, it will be vigorously developed. Mining where there is mine, logging where there is wood. If you don't have anything, you have to do everything you can to make the place rich.

Ten days later, Lu Bu talked about everything he could and finally ended the course.

At this time, more than 100 Xuzhou officials have all become talents.
