The harvest of about 12,500 catties is only three acres of land!

With a population of about 30 million people in Datang at this time, five catties of grain a day for one person, 150 million catties of grain can solve the food problem of everyone in the country for a day.

In other words, about 14 million acres of land is enough. At the beginning of the Tang Dynasty, due to the implementation of the equalization system, each adult man was given 100 acres of land as an adult, and 20 acres of land was left as a permanent field after death, which could be inherited from generation to generation. Therefore, it can be estimated that the amount of cultivated land at this time was about 300.4 million mu.

And now the yield of these three acres of land has reached the level of 4,000 catties per acre on average. If you count it this way, that large number of part-time jobs can feed the world on its own.

In other words, as long as everyone has these three kinds of seeds, even if the equalization system is abolished, one person is given ten acres of land, which is enough for everyone to eat and drink.

In that case, it was ordered that everyone who had land must plant one acre of corn, potatoes, and sweet potatoes, and the rest of the land should be planted with wheat, rice, vegetables, and fruits.

Not only that, but it can also completely raise a strong army with millions of male soldiers, millions of people who are well fed and paid. There will be no more troubles in the affairs of the frontier!

Moreover, the common people can eat and drink enough, and they can also have spare money to dress and build houses.

For a time, Li Shimin felt that the highest ideal of literati and politicians was the same in the world, and it seemed that he had the possibility of turning it into reality.

Of course, this is just Li Shimin's idea. In fact, the Juntian system that their father and son made is a big hole.

From ancient times to the present, only after the Republic of China, it has completely exceeded one billion mu of land, reaching 1.3 billion mu of land, and before that, it did not exceed 800 million mu of land at most.

Therefore, in a few years, three or four generations later, there will be no arable land in Datang to give to the people, but Li Shimin does not have this consciousness yet.

After Li Shimin's family's three acres of land were completed, they went to the side to accept everyone's worship. And for the rest of the land, naturally, there are recruited crop veterans to hurry up.

Because there are not many seeds, there are not many seeds. Soon, in less than an hour, all the ground was dug up.

A total of 20 acres of land, 5 acres of potatoes and sweet potatoes, and 10 acres of corn. The final total output reached a terrifying harvest of 60,000 catties. Of course, if there were not many people hoeing and leaf mounding to remove insects, about one-third of the harvest would have been reduced in these 20 acres of land.

But even if you drop it by one-third, you can still have a harvest of 40,000 catties, which is an exciting number.

After getting this satisfactory figure, Li Shimin gave some to the ministers on the spot, and Ye Mu naturally also had one, and it was the one with the most. And the rest, Li Shimin ordered it to be strictly guarded and kept as seeds for next year.

Looking at this harvest, I am afraid that it will not be a few years before it can begin to spread among the people.

It takes about four catties of seeds to plant one acre of corn. And planting an acre of sweet potato, starting from the seedlings, it takes about 80 catties. Potatoes cost 250 catties per acre of land.

Then this harvest will take away the reward. 10,000 catties of corn can be planted about 2,500 acres of land. There are about 12,000 catties of sweet potatoes, and you can probably grow 1,500 acres of land. The potatoes are the most, about 30,000 catties, but the ones planted are the least, only 120 acres of land.

If next year's corn harvest is counted as 1,000 catties and all of them are planted in the year after next, then there will be 625,000 mu of land in the year after next.

If you plant spring potatoes next year, the yield will be counted as 3,000 catties, and you can plant 56,300 acres of land the year after then.

Potatoes, on the other hand, will be counted as a harvest of 5,000 catties next year, and 2,400 acres of land can be planted the year after next.

Corn only needs the year after it is older to reach the whole country, while sweet potato needs to reach the whole country after four years, and the slowest potato will take about six years to reach the whole country.

Of course, this is the fastest algorithm, in fact, even the fastest corn takes six or seven years. However, there is no problem in spreading the whole country within 10 years.

When the whole production was known, the figure was obtained to the extreme, and a part of the reward was given out, and the emperor drove back to the palace.

Today is a big day, the emperor is happy, and orders that every year in the future today is the Fengnong Festival, and the court should have a three-day holiday, which can be implemented.

So all the officials went to their own homes.

In a blink of an eye, the three-day new holiday passed.

After the holiday, it is naturally time to go to court.

And the two most important things in the last dynasty today, the officials all know it.

The first is the cultivation of these high-yield crops.

The second is the matter of Ye Mujia, the champion of the Golden Branch, who became an official.

Above the court, Li Shimin sat on the dragon chair with joy, accepting the shouts of the ministers and the mountains.

The majestic saying of the public love is exempt, and the court meeting officially begins.

Li Shimin said a few words, focusing on the bumper harvest three days ago, and then began to inquire about the cultivation of new crops.

As the protagonist of bringing back new crops, Ye Mu is naturally the best of the best.

So Ye Mu stood up from the queue and said loudly: "Your Majesty, corn breeding, it takes four catties of seeds to plant one acre of land. Sweet potato...... Potato ......"

Ye Mu, who is from modern times, naturally dislikes the tirades of the ancients, as soon as he stands up, he is simple and simple, simple and clear, and all kinds of data are put out.

After saying that, there was no time to think, and basically everyone understood what needs to be done to cultivate new crops, how long it will take, and how many years it will take to spread throughout the country.

Li Shimin has never heard such a comforting recital, it is simple and clear, and it is clear at a glance.

Looking at Ye Mu's gaze, Li Shimin was even more satisfied. "This is an embryo of being an official, looking at this posture, he should also be a good hand at handling government affairs!" ’

"Good, good! Ye Aiqing said it well! Li Shimin's satisfied voice echoed in the Taiji Hall.

All the ministers also found it novel, and this way of reporting was unprecedented. For a while, everyone thought in their hearts that they would have to report like this in the future, which would save time and leave work early.

The court is a chore, in order not to make a fool of himself, he either does not eat in the morning, or only eats a little, and under normal circumstances, almost everyone comes to play without eating or drinking.

I got up at three or four o'clock in the morning to wash and prepare, waited at the gate of the palace at five o'clock, and then stood for more than an hour, and occasionally stood for two hours, or even three hours.

Hungry, numb legs and feet.

Therefore, all the officials have the desire to go down to the court early. Li Shimin is no exception!

Don't think that the emperor is comfortable when he sits, whoever is straight and straight, and maintains the posture of ** sits for an hour and his butt hurts for two hours!

Li Shimin was also pondering in his heart at this time, whether to give an order, and to report or report in the future.
