Chang'an, in the Royal Forest Garden, Li Jing summoned the Hubu Shangshu.

"Have you planted all the grain this season?"

Li Jing asked about the farming.

"Not yet, but seedlings are being raised everywhere, and they can start farming in a few days at the earliest."

The head of the household department answered truthfully, and the household department manages the household registration, the fields in the world, etc., and the problems of cultivation are naturally under their management.

Therefore, Tobe Shangshu knows everything about this season, when to raise seedlings and when to plant, after all, this is his job!

"That's good, you inform me that Guanzhong will reserve 3,000 acres of land this year, and I will use it to grow new things."

Li Jing nodded, and directly began to ask for 3,000 acres of arable land, which he planned to use to grow potatoes.

After hearing this, Hubu Shangshu was a little unhappy, now is the time when farming is busy, everyone is busy farming, and the number of fields in Datang is limited.

If you want to walk 3,000 acres of land at once, it is equivalent to planting 3,000 mu less grain, and when the harvest season comes, it is equivalent to 6,000 stone of grain less.

For such a bad behavior of Li Jing, Hubu Shangshu is severely condemning!

But he said: "Sage, the best time to sow seeds is now, if there are 3,000 mu of fertile land, it is equivalent to 6,000 stone of grain!"

Do you know how many people can be fed with 6,000 stone of grain?

If you don't know anything, you dare to do anything wrong and do such a ridiculous thing, and you are not afraid of arousing public anger!

In the eyes of Hubu Shangshu, Li Jing's behavior is really ridiculous, now is a good time to cultivate, but he came out to do things at this time.

Who knows what you're going to plant, judging by his understanding and cognition of Li Jing, Li Jing definitely hasn't done anything good!

"I naturally know this, otherwise I wouldn't have called you over, I have a new crop in my hand - potatoes, which can produce 50 stones per mu!"

Li Jing was going to plant potatoes, and made it clear to Hubu Shangshu that according to the fact that one mu of potatoes can produce 3,000 catties, which is converted into the Tang Dynasty's unit of measurement stone, it is 25 stones.

Coupled with the doubling of the yield of the system reward, the yield per mu is about 50 stones.

If 3,000 mu is based on this output, it is a full 150,000 stones.

If you want to grow grains, you need the yield of more than 70,000 acres of fertile land.

When Hubu Shangshu heard this, he gasped and was shocked by Li Jing's words!

He felt that Li Jing was too good at blowing, what kind of fairy grain could yield 50 stones per mu, and he didn't dare to dream of such a beautiful thing!

How dare Li Jing open his mouth to come, he didn't blush at all, is his cheek really thick to the point of being invincible in the world?

"Sage, please forgive the minister, where in the world will there be such immortal food, 50 stones per mu, the minister can't even think of it, if there can be 4~5 stones per mu, it is a great fortune in the world, how dare you expect so much?"

Hubu Shangshu saluted with his hands crossed, hoping that his words could make Li Jing wake up!

Li Jing's face turned black when he heard this, isn't this just a clear saying that he is bragging?

Alas~

What's wrong with this society?

Why is it that he tells the truth, but no one wants to believe it?

But fortunately, Li Jing had already ordered people to open up dozens of acres of land in the royal forest garden, and planted potatoes, and one acre can indeed grow 50 stones!

That is, one acre of land can grow 6,000 catties of potatoes, and with potatoes, in the future, there is no need to worry about running out of food!

If there is a natural disaster, you can use potatoes as a staple food, and you can also use them as a supplementary food on weekdays.

"I know you don't believe what I say, but what I say is the truth, fortunately, in this royal garden, I ordered people to reclaim dozens of acres of land."

"The yield per mu is about 50 stones, if you don't believe it, go and see with the management officials here, and you will know the truth at a glance!"

Li Jing said with a smile, sometimes, hearing is false, and it is true to see it with your own eyes.

Of course, sometimes, even certain things, what you see may not be true.

However, the potato thing is real, and there is not the slightest adulteration!

When Hubu Shangshu heard this, his jaw almost fell to the ground in surprise, and he saw that Li Jing looked confident, and he inevitably muttered a little in his heart.

Tobe Shangshu frowned slightly, and at this moment his heart began to shake a little.

Could it be that what the sage said is true? Is there really food in this world that yields 50 stones per mu?

"You are the internal official who manages here, take our household book to see if the potatoes I said can yield 50 stones per mu."

Li Jing ignored the surprised Hubu Shangshu, turned around and instructed the eunuch next to him to bring the Hubu Shangshu over to have a look and confirm the authenticity.

"Whoa!"

The eunuch received the order, turned to the household department and said, "Ge Shangshu, please come with me!"

"There is a Lao Neiguan to lead the way!"

Hubu Shangshu, who came back to his senses, responded with his hand and left with the eunuch.

After they left, Li Jing turned back to another eunuch and said, "Is the plow I want ready from the Ministry of Industry?"

"Back to the saint, the plow you want has been made, the Ministry of Industry has sent it, and the slave is about to report this matter to you!"

The eunuch hurriedly crossed his hands and saluted!

"Show me if I did what I asked!"

Li Jing showed a smile and asked the eunuch to bring the Quyuan plow, he wanted to inspect the goods to see if the Ministry of Industry was lazy, although the people in the household department did not dare to fool him, but who dared to guarantee that there would be no case?

Since ancient times, there are not a few people who deceive their superiors and subordinates, if someone thinks that he doesn't understand anything and is so foolish, he will cut corners!

"Whoa!"

The eunuch bowed with his hands crossed, took two steps back, turned and walked away quickly.

Soon, the eunuch came back with the Quyuan plow on his shoulder, put the Quyuan plow in front of Li Jing, and retreated to the side.

Li Jing stepped forward to take a closer look, and it was indeed made according to the design drawings he gave, and there was no mistake in the size!

Even the eleven parts of the Quyuan plough are a lot, and it can be seen that the craftsmen of the Ministry of Industry are not lazy!

Farm tool craftsmen have played a lot, although the Quyuan plow and the current plow, there are some differences, but some things are the same, the parts are not much different!

What's more, this is what the emperor wants, and this Quyuan plow is related to farming, so they dare not slack off, not only did they not cut corners, but instead used the best materials to make it.

Li Jing lifted the curved plow and felt the weight, it is indeed much lighter than the long straight plow used now, and it is more convenient to use.

"Not bad! The craftsmanship of the Ministry of Industry is good, you go and tell the Ministry of Industry to give me more curved ploughs, the more the better, and then distribute the curved ploughs to the people. ”

Li Jing put down the Quyuan plough in his hand and instructed the eunuchs to do things, he was not at all worried that the peasants would not use the Quyuan plow, in fact, the Quyuan plough was improved from the long straight plow.

"Whoa!"

The eunuch saluted and replied, "The slave and maid are going, does the saint have any other orders?"

Li Jing waved his hand and motioned for him to hurry up, he had nothing else to explain!

Not long after the eunuch left, Hubu Shangshu walked back, still with a look of shock on his face!

Until now, he still doesn't believe that there are really crops in this world that can produce 50 stones per mu.

Now that he sees it, this makes him secretly happy in his heart, if he can promote the immortal grain with a yield of 50 stones per mu in the whole world, the grain of Datang will be at least several times!

"Aiqing, how do you feel?"

Li Jing looked at the Tobe Shangshu who had not yet recovered from the shock, and asked with a smile.

"It's really shocking, the minister never thought that there was such a kind of immortal food in this world, today is really an eye-opener for the minister!"

Being asked by Li Jing like this, Hubu Shangshu came back from his surprise and had a smile on his face.

Think about how much food can be provided to the imperial court every year if potatoes are planted all over the world?

At the same time, I was even more puzzled in my heart, how did the saint get this immortal food?

"Now that you've seen it and confirmed that there's no problem, are you willing to give me the 3,000 acres of land I want?"

Li Jing nodded, and the reaction of the Hubu Shangshu was as he expected!

People in this era don't know what potatoes are, so they will naturally be curious about this new thing, especially when it can produce 50 stones per mu, and it is normal to be shocked to the point of disbelief.

But for Li Jing, a traverser, potatoes are just one of the daily foods, and there is nothing to make a fuss about at all!

"This matter, the minister will arrange it when he goes back, sage, I don't know how to eat this potato?"

Hubu Shangshu did not stop it anymore, and agreed very happily, now Li Jing doesn't want 3,000 acres of land, even if it is 30,000 acres of land, 300,000 acres of land.

He will not hesitate to get it for Li Jing, and then plant all the potatoes and wait for the potatoes planted in the soil to bear fruit!

By the way, Hubu Shangshu asked Li Jing for instructions on how to eat potatoes, a new food like potatoes, he had never even seen before, let alone eaten them!

"Potatoes can be boiled with peels, sliced and fried, stewed meat, etc., you can eat as much as you want, there is no special way to eat them!"

Li Jing said with a smile.

"The minister has been taught!"

Hubu Shangshu saluted with his crossed hands, and out of the corner of his eye, he just caught a glimpse of the Quyuan plow on the side.

Tobe Shangshu was stunned for a moment, and when he looked back, the plow in front of him was a little different from the plow he had seen before.

Tobe Shangshu turned around and asked, "Sage, is this a new plough?"

Li Jing nodded and said, "Do you want to know, how is this plough different from the long straight plough in your cognition?"

Tobe Shangshu nodded.

"This is called the curved plow, which is transformed according to the long straight plow, and the straight and long wheels are changed to curved and short wheels, and the plow disc that can rotate freely is installed at the head of the wheel."

"This not only makes the plow frame smaller and lighter, but also easy to turn and turn, flexible operation, and saves manpower and animal power."

"The long straight plough, when ploughing the land, the turn is not flexible enough, the soil is quite laborious, the efficiency is not very high, the curved plough is much better than the long straight plow, and the efficiency is also greatly improved!"

Li Jing introduced the Quyuan plough to the head of the household.

Quyuan plough first appeared in the late Tang Dynasty and appeared in Jiangdong area, and Quyuan plough is suitable for the characteristics of small paddy fields in the south of the Yangtze River.
