Zhang Xiu opened the letter and scanned it quickly.

He read the contents of Fazheng's letter at a glance. There is only one thing in the letter, that is, the sweet potato planted for the second time is about to mature and harvest.

Last time a sweet potato seedling produced only six sweet potatoes. Qin Ji and other farmers, who are good at farming, cut six sweet potatoes into pieces and planted them with the sprouted seedlings. They cut the seedlings one after another and planted a piece of soil.

Although not particularly many, there are also many.

Wait for this harvest, not 20 or 30 jin, at least a thousand jin.

After all, it's seedling planting.

When the sweet potato seedlings come out, they are continuously allocated by using the seedlings, so that they have the current scale.

After Zhang Xiu knew, her heart was also happy.

He looked at Wang Yue and said, "make arrangements. We'll go south to Hanchang County immediately. This time, take Li Ru and Sima Yi with them. The rest of them are in Chang'an and pay attention to the business of Daqin bank. "

"Here it is

Wang Yue went to arrange it immediately.

Zhang Xiu went back to the backyard and said something to Huang Yueying, Cao Jie and other girls. Then she got up and left. When Zhang Xiu came to the gate of the palace, Sima Yi and Li Ru had already arrived.

The reason why Li Ru was brought here was to let Li Ru have a look below and learn about sweet potato. For the sweet potato situation, Zhang Xiu is to inform the public.

Everyone knows.

It's just that there are doubts in every heart.

A grain yield of 5000-6000 Jin per mu is extremely terrible. From ancient times till now, it has never been. But all of a sudden, Zhang Xiu said that such a species, one by one heart, are suspicious.

Li Ru also had a great reputation among the people, so he took him there.

The rest of us must be in Chang'an.

After all, the business of Daqin bank may be attacked at any time, so someone must take charge to maintain the situation.

Zhang Xiu and his party did not take a carriage, but rode on horseback. All the way south, the speed is extremely fast, the average speed is more than 100 Li per day, the fastest time is 150 Li per day.

It was in the first ten days of March when it entered the territory of Ba County.

When Zhang Xiu came to Hanchang County, Fazheng met him directly on the official road. As soon as the two sides met, they went straight to the sweet potato planting site.

Now, his highness said, "when you go to the place where the sweet potatoes are dead, you can go to the greenhouse in large quantities."

"I've got to dig out a few of them. The output is really frightening."

"The highest yield of a sweet potato plant is more than 30 jin. Each sweet potato, on average, has three or four Jin, which is really frightening. And we've cooked it. It's very soft and glutinous. It can fill our stomach. "

Fazheng said: "sweet potato taste, is really fragrant, even more delicious than the rest."

Today's FA Zheng has been tried.

After all, he is the prefect of Bajun, as the person in charge, as the person who specializes in cultivating sweet potatoes. If he doesn't teach in person, it's hard to convince people, so he has already tried.

Li Ru had an unbelievable look in his ears.

The fruit of one plant is more than 30 jin.

It's a little scary. Of course, if it's true, it's the best.

"Go

Zhang Xiu waved her hand and couldn't wait.

They came to the greenhouse.

This greenhouse, now has turned off the floor heating, no heating, and open on all sides, the light is excellent.

Zhang Xiu looked at all the dead vines and the sweet potatoes planted in the whole soil, and her face was also happy. Without hesitation, he ordered, "reap!"

With Zhang Xiu's order, one by one farmers came forward.

Some people specially cut the dead vines of sweet potatoes to expose the bare land, while the others took hoes and began to dig sweet potatoes. When a hoe goes down, the soft soil is scattered, and sweet potatoes are exposed one by one.

At this time, some farmers specially wipe off the soil on the sweet potato, clean up the sweet potato, and constantly load the basket.

Li Ru's eyes widened at the moment.

Incredible!

It's incredible!

That's too much.

He carefully watched the farmer digging. Under the sweet potato vines, four or five of them were dug out, and they were all very symmetrical, and their sizes were not much different.

Sima Yi is also an eye opener. He has read a lot of books since he was a child. I never knew that there were such sweet potatoes in the world. Even the yield of sweet potato is so huge.

But Zhang Xiu recognized it at a glance.

And then it was planted.

So much so that today's harvest.

In Sima Yi's eyes, Zhang Xiu is somewhat mysterious. He is not only good at both literature and martial arts, but also invented rice paper and so on. He even knows sweet potato, which is really powerful.

"Congratulations to your highness, congratulations to your highness, we have nothing to worry aboutSima Yi bowed.

Once the sweet potato is popularized, it can be predicted that there will be no famine in the whole Daqin kingdom. Because sweet potato planting, enough to ensure that countless people have food to eat.

Li Ru suddenly said, "Your Highness, how to eat this sweet potato?"

Zhang Xiu said: "you can cook it and eat it, or you can cook it with rice. All in all, this is a very common way to eat. Of course, it's OK to eat it raw, but it's better to eat less. After all, it's raw. "

After that, he picked up a small sweet potato and asked Wang Yue to take a dagger and cut off the sweet potato skin.

Sweet, crisp.

It's delicious.

Zhang Xiu handed it to Li Ru and said, "come on, have a try. It tastes good."

Li Ru took a bite, raised his eyebrows, and said, "Your Highness is right. It's good to eat raw."

Sima Yi also took a bite and said with a smile, "this sweet potato is really good!"

Everyone was full of praise.

Fazheng's face was full of bright smile.

With the promotion of sweet potato, his achievements in Bajun have been impeccable. Fazheng's face was full of smile and joy from beginning to end.

Time goes by little.

In less than half an hour, all the sweet potatoes were dug up. After all, there were many people.

All the sweet potatoes on the scale, the final statistical results, a full 2300 Jin.

Zhang Xiu's eyes fell on Qin Ji and praised him: "Qin Ji, you are very good. This time you have a good harvest of sweet potatoes

Qin Ji said, "Your Highness, you are not worthy of praise."

"This time, we can produce so many sweet potatoes with a few sweet potatoes. In fact, only by continuously planting seedlings can we have the present harvest. If we go step by step, we will not be able to achieve this output. "

"Because when the sweet potato seedlings germinate and grow up, they can be cut and planted continuously. After they survive, we can cut them again. As a matter of fact, the last batch of cutting and planting are all worse. "

Qin Ji said: "after all, it's not as good as the first time."

Zhang xiudao: "this is already very good. Now this land is only about half an acre."

Qin Ji replied, "less than half an acre. Roughly speaking, the yield of sweet potato per mu can reach 5000 Jin."

At this point, Qin Ji's face suddenly burst into tears.

Zhang Xiu sees in the eye, but in the heart is some surprised, ask a way: "how to cry suddenly?"

Qin Ji said: "the reason why I cry is because in the past, when children were young, there was a famine at home. There was no food, so I starved to death. If you have this sweet potato, you can't starve to death. Even if you hang your life, you can hang it down. "

He was filled with emotion.

Because it's true!

If sweet potato can be promoted early, it will not be so.

Zhang Xiu, with a heavy face, said: "after the promotion of sweet potato, people will no longer be threatened by hunger in this world. After we have solved the problem of food and clothing, more people will be able to eat meat. "

"Your Highness is wise!"

Qin Ji spoke again.

Now he has great respect for Zhang Xiu. Because it was Zhang Xiu who discovered sweet potato, and Zhang Xiu specially told them how to plant sweet potato, so as to have the sweet potato now.
