“！！！”

Lin Yu'an looked at his brother in a daze.

Thirty acres of land......

I really didn't expect the emperor to play with words.

Is he poor?

As my brother said, at least those fields are nearby, and you don't have to travel far to take care of them.

In fact, as long as you clean up well, wasteland can also be turned into fertile land!

That night, Lin Yu'an dreamed of many agricultural videos of how to fertilize the fields, but many methods were not applicable, such as what biogas digesters, she really couldn't understand, but she still quietly recorded them.

In the end, she chose the fire-burning soil fertilizer method commonly used in southern Fujian.

This method is mainly made by piling up and simmering mountain soil, weeds, reeds and cow dung, etc., the advantage is that the insect eggs and grass in the soil can be cooked, and then there is almost no need to weed and control insects.

She also thought about the reason, that is, slash-and-burn farming in the past.

Lin Ruochen frowned lightly after listening to his sister's words, "Before planting, you have to use fire to burn the soil?" ”

Lin Yu'an handed a book to his brother to read.

That was still turned out by Yang Xian.

He is worthy of being the male protagonist in the book, and now he has activated the aura of unforgettable, when Lin Yu'an said that he wanted to find a book about slash and burn, he immediately found a few books.

Lin Yu'an pointed to a page in the book.

"Brother, you see, in the past, when there was not so much fertile land, everyone would cut down trees, dig up the grass and trees in the ground, and then burn them with fire after they were dried.

Of course, Lin Ruochen understood what his sister said, but this method had drawbacks, and his husband told him when he went out to study.

"Fields that have been cultivated in this way are usually replanted after one year and then replanted."

"Ahh Lin Yu'an immediately put on a 'bitter face' and asked puzzledly: "Why do you have to change the land in a year?" ”

Lin Ruochen couldn't help but reach out and rub his sister's little face again, "Because after a year, that land will become very barren and it will be impossible to grow anything." ”

"Why can fertile land be planted all the time?"

Lin Yu'an carefully guided the topic.

"Because everyone fertilizes the fertile fields, and the soybeans used to make tofu were originally planted as green manure."

Finally brought the topic here!

Lin Yu'an lowered his head, hid the excited tears in the corners of his eyes, and continued cautiously: "Wouldn't it be nice to add the field fertilizer you usually use to the soil and burn it together?!" ”

"Burn together?"

"Yes, yes! When I burn the soil, add some manure and burn it together, and my field can be fertilized and turned into a fertile field! ”

Lin Yu'an's pretended to be naïve, which made Lin Ruochen fall into deep thought.

Does this method work?

Seeing that he didn't speak for a long time, Lin Yu'an was a little anxious, so he asked again, "Why don't we find someone to ask?" And give it a try? ”

Lin Ruochen raised his head sharply and looked at her in a daze.

That's right, I'm not good at farming, so it's better to find someone who is good at asking and doing some experiments.

"Okay, I'll let Uncle He find it."

Lin Yu'an quietly breathed a sigh of relief.

If you do this, you shouldn't be in the limelight, right? After all, the method was not directly proposed by her.

She thought of the reminder letter from before, and her mood was a little complicated.

If the other party is also a wearer, maybe it will be easier to do things in the future... bar.

She was a little unsure.

But in order to have a better time in the coming days and things go more smoothly, Lin Yu'an decided to talk to Xixi's brother.

It's just that Lin Yu'an didn't expect that as soon as he mentioned the meeting, Xixi ran away again.

"Heeki, come back!"

It's a pity that before the words fell, Xixi had already run away.

Lin Yu'an stood anxiously at the door and waited, Qinghe asked her to go back to the house and wait, but she was unwilling.

About two quarters of an hour later, Hiki ran back with a gust of snow.

"It's not urgent, can't we wait until tomorrow to ask? What if I catch a cold?! Next time, I won't be able to make a delicious meal for you! Lin Yu'an took the snow brush painfully, swept away the snowflakes on Xixi's head and body, and kept chattering in his mouth.

Qinghe, who originally wanted to help, also plugged in. I didn't get started, so I had to cover my mouth and retreat to the side.

She is used to such a disobedient picture these days.

Xixi looked at Lin Yu'an pitifully.

"Alright, okay, remember not to do that next time!" Lin Yu'an glared at her angrily, this little guy is getting better and better at pretending to be pitiful, he must have been damaged by the little fat dun!

"Hmm!"

Xi Xi smiled and hugged Lin Yu'an, and then took out another letter.

There were only three words in the letter: "Give it to me".

Seeing this, Lin Yu'an breathed a sigh of relief for some reason, obviously she had only met once, but she just had a feeling that Xixi's brother was very reliable, was it because of Aiwu and Wu?

Lin Yu'an turned to look at Xixi, "What did you say to your brother?" How's the meeting going? ”

"Burn the earth! Too busy to see. ”

“……”

All right.

The next day, Lin Yu'an went to see her thirty acres of land again.

Yesterday she was frightened by the wasteland, and she didn't check it carefully, but today she wants to take a good look at the surrounding environment and consult the water source.

It's just that after getting off the donkey cart, Lin Yu'an was stunned again.

The land was still the same barren, but the stones and debris in the field were picked up and piled aside.

Could it be him?

Lin Yu'an immediately remembered Xixi's brother, but she just looked at Xixi, and Xixi shook her head and said she didn't know.

"Who could that be?"

"Xiangjun, the slave will help you ask." As soon as Qinghe finished speaking, he ran to the side and went to ask the people in the Zhuangzi.

Lin Yu'an was a little helpless, every time she heard everyone call her hometown, she was not used to it.

But this title must be changed, if you continue to let everyone call her Miss, someone may run to make a small report, saying that she was canonized and the township monarch is not satisfied.

Alas, my heart is so tired!

Sometimes she wonders if she's too timid.

After a while, Qinghe ran over with a smile, "Xiangjun, I asked." ”

"Then hurry up."

It turned out that after Lin Yu'an left yesterday, the head of the village asked the farmers to help clean up the fields.

Lin Yu'an was a little surprised, she glanced at the bankers who seemed a little restrained.

"Was it forced?"

Qing He smiled and shook his head, "It's voluntary." ”

"Why?"

Lin Yu'an didn't quite understand.

"Ah, this slave didn't ask." Qing He lowered his head in annoyance, it seems that he is still not thoughtful enough!

Steward He smiled and said, "This old slave probably knows." ”

Lin Yu'an looked up at him, "Uncle He said quickly." ”

"There are many families in the village who have learned how to make tofu, and now it is a slack time, so they carry the finished tofu and sell it, and the money they get can be used for a good year. I think they helped clean up these wastelands just to thank the young master and the townsman for announcing the recipe. ”

Qinghe: "Slave and maid go and ask again!"
