After thinking about it for a while, Su Jinli knew it in his heart.

The yield of potatoes cultivated in the space is quite high, but if you get to the border, the environment there is not as good as in the space, and the yield will definitely be affected.

However, even if it is affected again, the yield per mu should be able to reach 1,000 catties.

This thing can be used as a staple food, although it will definitely be very unaccustomed to being used as a staple food compared to rice flour.

But the border conditions are so bitter, even if the soldiers can't eat enough, who will dislike potatoes?

This stuff can also be made into potato vermicelli for a change of taste.

The problem is that one mu of seeds alone costs two or three hundred kilograms, and if the yield per mu is only one thousand catties, then after deducting the seeds, the net harvest will be two or three hundred kilograms, which is a bit less to be honest.

The advantage is that potatoes are cold and drought tolerant, and they are suitable for growing in places where water is scarce in the north.

If she wants Chu Yan to bring it over, it will be almost the same if she brings a thousand kilograms. When the time comes, plant a few acres and use them as experimental fields, so that people can serve them well, and maybe the yield per mu can be more.

If there can be an output of two or three thousand catties, or even three or four thousand catties, the people at the border will not be happy and crazy?

Sweet potatoes are even more trouble-free, this thing can be raised with seeds, and after growing into vines, you can cut vine seedlings to plant.

So the cost of seeds is not that large.

An acre of land only needs 100 catties of seeds, and if you cut more vine seedlings as seeds, you can plant more.

And the yield of sweet potatoes is higher, the sweet potatoes in her space are not only large, but also very sweet, and the yield per mu is more than 10,000 catties.

After getting outside, if the output can reach 5,000 catties, it will be crazy enough.

However, sweet potatoes are not as hardy as potatoes, and if they are planted at the border, they don't know how much they can yield.

The young leaves of the sweet potato vine can also be used as a vegetable, and the old vines can be used to feed pigs and cows.

When you plant more in the future, you can also raise more pigs at the border.

Then there is corn, the corn in her space, the yield per mu is 2,000 catties, and there are not many seeds used to plant an acre, as long as four or five catties of seeds.

If you get it outside, the yield will definitely drop a lot, but this thing tastes good, when it is fresh and tender, it can be used as corn shoots to stir-fry, and then larger, you can boil it in water, stew pork ribs, make corn steamed buns, and wait until you are old, you can also grind it into corn flour to make steamed buns.

This time I went to the border gate, and I brought 2,000 catties of potatoes, which can almost be planted on five acres of land.

1,000 catties of sweet potatoes, at least 10 acres of land can be planted, and if you pick more vine seedlings, it will be no problem to plant 20 acres.

If there is a lot of open space over there, you can pick a few more vine seedlings and plant more.

If you bring a thousand catties of corn, you can plant 200 acres of land, which is not less.

Anyway, it's just to go to the border to test the water, and when the harvest is over, if the yield is good, it can also make people more confident in the mutual market.

However, the capital has to hurry.

The border pass is just to test the water, and if you are here in the capital, I am afraid that you will have to use it as a seed in the future, of course, you have to serve more carefully, and strive to harvest more good seeds.

After Su Jinli finished thinking about this, he sent someone to the pharmacy to go to the medicinal materials and prepare various pills for Chu Yan.

On the other side, Chu Yan was not idle, after he left Su Jinli, he went to the staff to discuss the matter of going to the border pass, and arranged various affairs in the capital by the way.

When Chu Yan finally finished his work, he heard that Su Jinli sent someone to the pharmacy to get a lot of medicinal materials.

As soon as he heard it, he guessed that Su Jinli must be trying to do something, and couldn't help but run to find Su Jinli.

By the time he looked for it, Su Jinli had already made the pills. The main thing she does is antidote pills, gold sore medicine, and some Pei Yuan Dan that regulates the body.

The antidote pill is to prevent someone from poisoning Chu Yan, and the gold sore medicine is used to treat wounds. Pei Yuandan Chu Yan doesn't need this thing, his body is very good, but there are many generals in the border pass, and he is afraid that his health is not very good, and he can be recuperated by eating this.

Chu Yan took Pei Yuandan over, and he could also gather a group of people.

She put the prepared medicine in the box, and when she saw Chu Yan coming, she pointed to the box on the table: "I have prepared some medicine for you, you can take it with you when you set off." ”

After a pause, she said, "Master said that the seeds will be sent over in the near future, and I don't know exactly when." But according to him, there should be a lot of seeds.

If he brings the seeds before you go, you can take some with you to the border and see if you can grow them. What do you think? ”

Of course, Chu Yan said yes and agreed.

He didn't know what those seeds were for, so he didn't pay much attention, and when he spoke, he opened the box with two minds.

Su Jinli saw that he didn't care, so he had an idea.

She took out some corn flour and asked Ruyi to make fluffy and soft small steamed buns, and took out some potatoes and sweet potatoes, and asked Ruyi to make potato roast beef, roasted sweet potatoes and shredded sweet potatoes.

At this time, although beef cannot be slaughtered at will, there are always cattle that have died for one reason or another, and as long as the government has inspected them, they can be bought and sold.

As the princess of Qin, it is not difficult for Su Jinli to eat beef once in a while.

When eating, Chu Yan couldn't help but be a little stunned when he saw the dishes on the table.

He had eaten braised beef, but he didn't recognize the potato pieces.

When Su Jinli took out the box before, the potatoes he saw had not yet been peeled, but now they were not only peeled, but also cut into pieces and made into roasted vegetables.

How could he recognize it?

"What is this?" Chu Yan picked up a piece of potato and asked Su Jinli in surprise, "I don't seem to have seen it before." ”

As a prince, he didn't dare to take food lightly.

"This is given by the master, I heard that it is called potatoes, didn't I show you the seeds before? You saw it at the time. It was said to be edible, so I asked the kitchen to make some to try. ”

Su Jinli explained a few words, and then sandwiched a piece of potato in front of Chu Yan and ate it.

When Chu Yan saw that she was eating like this, he was suddenly a little anxious: "Why did you eat it?" ”

Su Jinli pretended to be puzzled: "Why can't you eat it?" They all say that this thing can be eaten. Taste it, it tastes pretty good. ”

Chu Yan was still a little worried, but when he saw that Su Jinli had eaten it, he was worried that if he didn't eat it, Su Jinli would not be happy, so he also sandwiched a piece to taste it.

He took a cautious bite, then raised an eyebrow.

The potatoes are very soft and glutinous, full of roast beef, and they are actually good to eat.

He had eaten beef roasted with radish, but the taste of radish was relatively strong, and he didn't like it very much.

This potato tastes better than a turnip. Not only soft and glutinous, but also a special fragrance.

So he looked at the other dishes, pointed to the roasted sweet potatoes on the plate, and asked, "What is this?" It looks a little familiar, and it's the same seed you showed me that day? ”

It's really roasted sweet potatoes that smell so fragrant and sweet that people can't refuse.
