People are in the Tang Dynasty, creating a mythical dynasty

And his words made everyone present tremble again.

Thirty jin is a jun, and four jun is a stone.

Four stones and one jun is 510 catties.

And this is only the output of forty square meters.

Chapter 81 The Beginning of Reservoir Construction

With a planting of 510 square meters and a yield of 2000 catties, the yield per mu is almost 5000 catties. Even Li Ming has never thought of such a value. You must know that it is the efforts of later generations to refine planting and modern fertilizers Under normal circumstances, the yield per mu of potatoes is about 8000-[-] catties; the yield of non-heavy cropping land is higher, up to about [-] catties; only some top potato varieties, coupled with scientific management, can reach tens of thousands per mu catty.

Now in this more than 1000 years ago.

There is no scientific management, nor modern fertilizers and pesticides.

The yield of potatoes per mu is as high as nearly [-] catties.

Such a result can be said to be incredible.

It's also very exciting.

Eight thousand catties per mu can almost instantly solve the food problem of the entire Tang Dynasty.

Pig farming, as well as the development of other breeding industries, have no restrictions at all at this moment.

Raising pigs on a large scale, impossible?

No, this moment became possible.

At this moment, Li Ming only felt that his breathing was involuntarily heavy.

In particular, he knew that the potato species in front of him were experimental species that would not disappear due to the characteristics of the next generation.

Now that the yield per mu can be maintained at [-] catties, then if the next generation is cultivated well, it can also reach the yield of [-] catties per mu.

Such a multiple increase will reach an extremely terrifying level.

Just three times.

The quantity of potatoes can reach millions of catties.

If it takes two or three years, the entire Tang Dynasty may not have food problems.

How not exciting.

And in excitement.

Li Ming quickly made a decision.

One order after another was issued quickly.

The first was to lead his potatoes south.

The most important thing about potatoes is planting rotation. If you want to maintain high yield, planting rotation is inevitable.

It is naturally impossible for the second wave of planting to be in Guanzhong again, or even in the north.

After all, it's not just a matter of planting rotation, but also a matter of weather.

The north, which is about to enter autumn, is not suitable for planting.

Even if it is planted, the growth of potatoes is prone to major problems.

So Li Ming directly chose the south.

Five hundred catties of potatoes were all taken away.

brought to the south.

And they have only one goal, to plant the five hundred catties of potatoes directly.

All the people who planted were still the dozen or so people before.

If potatoes can still maintain a yield of more than [-] catties per mu, these [-] catties of potatoes are enough to produce [-] catties of potatoes.

And compared to the weather in the north, it only takes four to five months in the south to harvest, and the speed is undoubtedly faster.

If the preparation is good, not to mention three crops a year, two crops a year can undoubtedly be easily achieved.

And when the third reharvest, the potato spread problem will be completely solved.

Li Ming is still looking forward to this.

But now he is also doomed to be unable to put all his thoughts on Tudou.

Cheap Daddy gave him the most urgent problem at present is the construction of the reservoir.

So after arranging the potatoes, his mind turned to the reservoir again.

Two months down.

Preparations for reservoir construction have been gradually completed.

The first construction plan was determined.

Secondly, the steel output of blast furnace ironmaking has also accumulated more than 50 jin. Although it is not worth mentioning compared with later generations, in this era, what we are facing is only the Bahe River, not the Weihe River, let alone the Yellow River. The need for reservoir construction in this era.

Especially when the people from the Ministry of Industry and the Shaofu inspected the entire Bahe River and determined the location of the reservoir.

This problem is not even a problem.

Bahe River, known as Zishui in ancient times, originates from the north of Majiapo, Bayuan Town, Lantian County, on the north slope of Qinling Mountains, flows through Baqiao District and Weiyang District, and flows into Weihe River between Weiyang and Baqiao Districts of Chang'an.

The reservoir area chosen by the Ministry of Industry is between Weiyang and Baqiao districts.

here.

The water flow has now gradually calmed down.

The huge plain is enough to dissipate the greatest momentum of the entire Bahe River, and a reservoir is built here.

It is enough to calm the flow of the Bahe River into the Weihe River, which can not only solve the problem of the Bahe River, but also solve the problem of the Weihe River in one fell swoop.

Compared to other places, this place is undoubtedly the best.

Although the area to be built is larger.

But the required material structure requirements are also much lower.

The current situation is enough to complete.

Shaofu.

People gradually gathered.

Even Qin Huaidao and Cheng Chuliang rushed back half a month ago.

Their banner, from the original 2000 people, has now recovered to 1 people.

Moreover, these 1 people are different from the previous 1 people. They are laborers who can fully devote themselves to production and life.

For those who lost their land, they almost knew how to choose the Shaofu's treatment without even thinking about it.

As for Qin Huaidao and Cheng Chuliang, they undoubtedly had a different experience at this moment, and there was no initial resistance.

"Is the construction period here a bit tight?"

Li Ming frowned and opened his mouth, looking at the people in the Ministry of Industry and the Shaofu.

The place chosen by several people is undoubtedly the most spacious place.

And the most spacious place also means that it will take longer.

Li Shimin only gave him one year.

A lot has passed now, and there will undoubtedly be less time left for construction, even he has to worry.

"Your Highness, don't worry, it should be enough."

"According to the method mentioned in His Highness's book, I have already tried it, and it is extremely feasible. I believe that with General Qin and General Cheng's troops, it will be enough to complete the repair in less than a year."

An official from the Ministry of Industry replied with a smile, with a calm expression on his face.

As for the construction period, they naturally considered it.

Although one year is indeed a bit tense.

But with the method of rapid construction in later generations, and the connection between Bahe and Weihe is not as huge as later generations, it is naturally possible to do it.

In particular, Qin Huaidao and Cheng Chuliang brought 1 people.

In addition, there are 1 people recruited before.

Although it is impossible to get all of them, it is not a big problem to reach one third.

More than 3000 people built it together.

Not to mention within a year, half a year is enough to build it.

"it is good!"

"Get started now!"

"My king needs a more complete plan."

Li Ming nodded and spoke immediately.

"promise!"

The figure responded quickly without any hesitation.

Soon, when the next day comes.

The Ministry of Industry official quickly submitted the plan to Li Ming.

The plan is opened.

Lines of words written with brushes caught his eyes.

Li Ming also began to get serious immediately.

The plan was not simple. Although it was just a matter of building a reservoir, the things contained in it involved all walks of life. For a while, Li Ming became a little serious.

And this seriously.

Even he couldn't help being surprised.

Because this plan is not much different from the plans he signed in, and even in this era, this plan is more suitable.

Chapter 82 Flood Dragon Walking Water, Prelude to the World

When the afterglow of October gradually arrived, the first year of Zhenguan gradually came to an end.

The locust plague that was originally sweeping was about to subside at this moment.

The large-scale grabbing has caused the number of locusts to rise to countless heights in an instant.

The construction of the reservoir began in a mighty way.

A lot of steel, a lot of cement, and stones are heading towards the Bahe River.

A construction team of more than [-] people led by Qin Huaidao and Cheng Chuliang also started their work.

If nothing else happens, they will be living under construction for a long time to come.

Compared with the original [-] engineering team.

Today's 1 talents can be regarded as real engineering teams.

The power it can mobilize is undoubtedly stronger.

In the past few months, these 1 people have also been trained by Qin Huaidao and Cheng Chuliang to obey them.

Even building a reservoir will not be a problem.

Soon after the curtain was drawn.

It quickly entered the state.

As for Li Ming, naturally he didn't need to do it himself, all he needed was to govern the entire Shaofu.

And his workload is still very easy.

Just a little complicated.
