What could it be?

Isn't he the one who wants her to be so capable?

The capable daughter-in-law who picked herself has to bear it even if she kneels!

Putting away his thoughts, he hurriedly sat down opposite her and talked to her in detail.

"Let's talk about sweet potatoes first, I didn't know about this thing before, and I didn't know how much yield per mu was good, but in my opinion, it was good. We planted a total of ten acres of land, and we produced about 178,000. ”

Eighteen thousand catties, this output is not high, but Yu Shu still nodded with satisfaction.

The yield of sweet potatoes in later generations is very high, at least the same harvest of 5,000 catties per mu, and some can even reach tens of thousands of catties.

But that's because later generations not only have a variety of targeted fertilizers, but also the seeds of later generations have undergone countless experiments and practices, and the hybrids with the best genes have been improved.

And the sweet potatoes she brought obviously don't have those advantages.

can reach a yield of nearly 2,000 catties per mu, maybe thanks to the fertility of the black soil.

"Don't dislike this small yield, this yield is really not high, but when you open all the deserted cities next year, the output will be gratifying."

Chu Yu nodded approvingly, as far as he was concerned, it was good news that there were 10,000 catties of sweet potatoes for ten acres of land, even a few thousand catties.

From now on, the deserted city with nothing will be a land where crops can be grown and food can be produced, even if it is a very meager output, it is a great progress.

So, he didn't dislike it at all.

"I'm not disgusted, I'm happy, really. Shu'er, if it weren't for you, maybe I would still be worried about what to do with such a large wasteland. Although you said that this sweet potato contains more flour and cannot be eaten as a staple food, in my opinion, it is much better to have this than to gnaw on mud and bark. ”

Yu Shu nodded, and what she said was not a staple food is only in the long run, but in the famine years, sweet potatoes are a lot of staple foods, and they are better than nothing.

"Let's talk about the rest."

"I'm not busy, you wait first, I'll go get something."

As he spoke, the whole person got up from the bed, ran to the ground, took out a booklet from his coat, flipped through it, and handed it to Yushu.

"You know, I have a lot of things going on every day, and even if I stay there, I may be able to keep an eye on them every day. But Yunfei worked carefully, and he was afraid that he wouldn't be able to remember too many things, so he wrote down the doubts in the book, you can take a look at this page.

I remember that he said that it seems to be more than 10,000 catties of sweet potatoes, and the yield of the first five acres of land is more than 2,000 catties, but the additional five acres are far less than the first few acres, even if the time is a little later, it shouldn't be so different. Did you say this in the book you read? ”

Yu Shu picked up the booklet and glanced at it, and saw that it not only recorded the yield of each crop in detail as Chu Yu said, but also recorded the land in blocks, and there were marks with cinnabar next to those who had doubts, which was extremely detailed.

At this moment, Yu Shu couldn't help but nod with relief, it was really in vain that she hurt that stinky boy in vain.

But the reason for the huge difference in output, Yu Shu couldn't help but touch his nose with a weak heart, and secretly calculated in his heart.

In fact, to be honest, she didn't know the specific reason.

After all, she didn't study botany, but in the face of Chu Yu's hot eyes, it seemed that it was wrong for her not to say something.
