The Empress traveled through time and space, and she fought for supremacy in the troubled times

"fertilizer?"

Another word I haven't heard before.

"Yes, in fact, the human excrement you use here can be considered a type of organic fertilizer."

I don't know when it was discovered that using human excrement to irrigate crops will make the crops grow much better.

That’s why there is a saying that good things should be kept within the family.

"One of these?"

Yun Zhi knocked on the table and looked at her, "So there are other things that can be used as fertilizer?"

Tang Qiuwan nodded vigorously, "My Lord, this is true. Every fertilizer has a slightly different effect."

Yun Zhi pondered for a moment and looked at Liu Anruo.

Liu Anruo understood and took out the pen, ink, paper and inkstone and placed them on a small corner of Yunzhi's desk.

Seeing the actions of the two people above, Tang Qiuwan below was secretly amazed. Isn't this just like in TV dramas where the master only needs to give a glance and the people around him know what to do?

It turns out that you can really know what the other person is thinking just by looking at them.

This is too awesome.

Didn't the Lord just raise his head? I didn't see anything in his eyes.

But what are you going to do with these? Is it to record what she said?

Just as she was thinking, Yun Zhi's voice came over.

"Tang Qiuwan."

"what?"

Yun Zhi pointed to the plain paper beside her and said, "Write down what you know about the fertilizers we have here."

"it is good."

Tang Qiuwan walked up carrying her slightly long clothes.

Tang's mother deliberately made this dress longer, thinking that she could grow longer and wear it for a few more years.

Before Liu Anruo brought up the feast below, Tang Qiuwan sat directly on the ground.

She picked up the brush placed aside, dipped it in ink, and started writing on the paper.

Talking while writing.

"Just as I mentioned, human excrement is organic fertilizer. Actually, livestock excrement is also organic fertilizer. For example, the horses we raise here, their feces and the grass left on the ground after they eat, when mixed together, become fertilizer. It is very useful."

Yun Zhi even hired someone to take care of the more than one hundred horses in Yunjiazhai.

As for the horse manure, it was removed every day by those hardworking people.

Yun Zhi nodded thoughtfully, and it seemed that he would let those people keep him.

She turned her head and looked at what Tang Qiuwan had written on the paper, and was stunned.

Liu Anruo, who was always paying attention to Yun Zhi, also looked in the direction her gaze followed.

This sight made her frown.

How could someone write like this?

Not only are the characters large, but the thickness of each stroke is also uneven, and some are even mixed up so that you can't tell what the characters are.

Also, why should the words be written horizontally and from left to right?

Is it true that the learning over there only involves learning knowledge and not learning how to write?

Liu Anruo took the pen and paper from her hand and said, "Miss Tang, come and talk, let me write."

Seeing Liu Anruo's actions, she guessed that it might be because she didn't like her handwriting.

Tang Qiuwan scratched his red face and explained hurriedly: "We don't use this writing method over there, so I don't know how to do it."

After all, she learned calligraphy from calligraphy class in elementary school.

Liu Anruo raised her eyebrows and looked towards her, "You don't use this over there?"

"You don't need this. By the way, you can try making a quill pen out of goose feathers. It writes very well too."

"quill?"

Yun Zhi looked at her in surprise, "What is this?"

"You can use goose feathers, or any other bird feathers. Cut off the feathers and leave..."

She measured the length with her hands and said, "This is about right."

"Then there will be a layer of something on the feathers, which you need to pick off with your fingernails. Also, don't forget there is a thin film inside the tube, which you also need to remove."

"The last step is to sharpen the tip, which means beveling it, leaving one side, and then trimming it into a sharp corner. Then, carve a notch on the corner and it's done."

"But you can only write a few or a dozen words with just one dip of ink."

I made this for Tang Qiu Evening Party because I saw a video of it before and I tried to make it on a whim.

Yun Zhi looked at her seriously and said, "Thank you for telling me. This will be very useful to us."

She waved her hands, somewhat flattered, "No, no, I'm glad I could help you."

Here, so many people choose not to study. In addition to the tuition fees for private schools, the cost of pens, ink, paper and inkstone is also a huge expense.

Just like today, people in Yunjiazhai learned to write by writing with water, or by writing with wooden sticks on the sand, or by writing with charcoal.

If the quill pen can be popularized, it will be of great benefit to learning to read and recognize words.

Yun Zhi thought for a moment and said, "Let's talk about this later. Now let's talk about what can be used as fertilizer."

"Hey, good."

Liu Anruo dipped the pen in ink, held it in hand and looked at Tang Qiuwan.

"Wood ash is also a fertilizer and can be mixed with water. It contains potassium and can kill bacteria and disinfect."

"There's also green manure, which uses plants as fertilizer and is plowed into the soil. Examples include mung beans, milk vetch, and alfalfa..."

"And bones, any bones will do. Grind them into powder. They're rich in protein and have a long-lasting fertilizer effect."

In this way, Tang Qiuwan said a sentence and Liu Anruo wrote a sentence.

Looking at Liu Anruo's pleasing handwriting, Tang Qiuwan showed envy.

It took me half an hour to finally memorize it.

"Okay, that's about it. Anything else would be too complicated. These are enough."

Liu Anruo stopped writing and handed the finished content to Yun Zhi.

Yunzhi took it and took a quick look at it.

"Tang Qiuwan, it will be time to plant winter wheat soon. I'll leave it to you to figure out how to use this fertilizer then."

Tang Qiuwan patted his chest and said, "It's a small matter. Leave it to me."

……

Look at what's posted on the notice board.

A group of people gathered around.

"What's that on top?"

"It seems to be some kind of fertilizer. Using this can increase the yield."

"What! So magical?"

"Yes, this is what Miss Tang said. Miss Tang is a person who has been gifted by heaven. There is no falsehood in what the gods teach. I will go back and collect these things."

"It's amazing! Bones can even increase production. I guess we can't throw away leftover bones anymore."

"Yes, we need to collect them and prepare to plant wheat."

A wave of people comes and goes.

After watching, the onlookers all went back to collect these things.

For subsequent needs.
