Old Mu is a carpenter, and he can tell the purpose of a board just by touching it, but now he's dumbfounded: What is cardboard? What can it be used for?
Han Ming also wanted to see what could be made from cardboard, so he urged Mu the carpenter to get started.
Due to space and technical limitations, Song Liyun could only produce corrugated cardboard that was 50 centimeters long and 30 centimeters wide.
The pulp is made from tree bark fibers and reeds, with acorn starch and millet flour as binders. Clay is added to the pulp to increase its hardness and viscosity.
To be honest, the paper they made was of really good quality.
If there are no conditions, create them.
There is no machine-made roll core; each cardboard sheet has a small, hand-twisted paper roll as its core, with cardboard glued to both sides.
This makes each board not only sturdy, but also ensures that the paper surfaces on both sides are smooth and delicate.
If needed, they can be easily pieced together into large sheets of cardboard.
Carpenter Mu had no experience in making woodwork with paper. Following Song Liyun's instructions, he used overlapping and mortise and tenon joints instead of wooden nails to make cardboard boxes from cardboard.
The box was a bit strange; it had no lid, only four loose pieces of cardboard covering it.
It's so light it's almost flimsy, and it won't break if you drop it on the ground.
Moreover, once the bottom plate is removed, a few folds and the sturdy cardboard box can be transformed into a stack of cardboard like magic.
Once unfolded, it becomes a sturdy cardboard box that can be reused.
Han Ming clicked his tongue in amazement.
Despite participating in the entire production process himself, he still couldn't understand how those tattered, withered grass and tree bark could be turned into boxes.
Moreover, as long as the box is filled with things, it can withstand the trampling of this man.
This is... absolutely amazing!
In April, the town of Suijin was already bustling with life at dusk. Farmers who had finished working in the fields outside the town walked together and talked about the drought situation in the soil this year.
It's already April, and there hasn't been a proper spring rain yet.
The Broken Gold Guard dropped a water-cutting stone under the bridge archway below the pass, and now the Yellow Sand River is filled with water.
There is no problem with irrigation water for the land outside Suijin Town. All that is needed is to dig a ditch to bring water into the land, and every piece of land is a fertile field that is guaranteed against drought and flood.
Since returning from Pingyang Prefecture, Song Zhenping has not followed his previous plan to plant coarse grains. Instead, he has used the rice seeds he bought in Pingyang Prefecture to cultivate seedlings, intending to grow fine grains on this large plot of land.
The rapeseed seedlings planted in spring have also grown.
The germination rate of the seeds from the natural environment was much better than that of the greenhouse in the backyard, with more than a hundred seedlings. In addition, there were two rapeseed plants in the backyard that were about to bloom, so there would be some harvest. He was not worried that the divine seeds would become extinct.
Farmers all love to come and see the Song family's land.
Because Song Zhenping's planting methods are quite different from theirs.
What are row spacing and seedling spacing, what is soil temperature seedling raising, fire temperature seedling raising? Many of these terms sound like gibberish.
Song Zhenping is very open-minded and tells everyone he knows, but... not many people are willing to listen to him.
Everyone is used to growing corn, millet, sorghum, and potatoes as staple food, and also growing peanuts and sesame seeds to make oil. That's enough to feed a family.
Fine grains like wheat and rice require advanced technology; a slight oversight can lead to total crop failure, so they try to plant as little of them as possible.
Besides rice, Song Zhenping also grows a large amount of sesame, peanuts and broad beans, all of which Yun'er said can be pressed for oil.
As evening fell, Song Zhenping led Ju Qingma into the courtyard and was startled by two square-headed monsters rushing towards them.
Xiao An and Hei Jin each carried a yellow cardboard box on their heads and ran around the yard, just like the big-headed deities who used to visit the village during the Spring Festival.
"Xiao An, you can't see the ground properly, be careful not to fall!"
Upon hearing her brother's voice, Xiao An rushed over diagonally, nearly crashing into Ju Qingma.
Startled, Song Zhenping quickly grabbed him.
Xiao An took the cardboard box off her head and asked Song Zhenping with a grin, "Brother, are you tired?"
Although the medicine from the substitute doctor was expensive, the ointment was very effective. Xiao An had been taking it for almost a month since returning from Pingyang Prefecture, and his speech had become noticeably more fluent and clear.
Song Zhenping patted his head: "Not tired!"
It's spring planting season now, and although he works in the fields every day, he's not hungry and has plenty of energy. He used to have a very easy time farming 15 mu of land in Xiaoshi Village.
Moreover, when there's a lot of work to be done, soldiers from the garrison will come to help.
The seeds have already been sown; now all he does is check on the germination of the seeds while the horses are being released.
Song Zhenping frowned at the thought of the soldiers in the garrison: another soldier wanted to propose marriage to Yun'er today, and asked Commander Xiao to act as matchmaker again, but he refused!
In the past two weeks, I have already turned down five offers.
Some wanted to marry into the family, some wanted to get married, and some even offered a dowry of ten taels of silver...
This group included Wang Qi, who also refused.
well!
I'm afraid I'll offend everyone in the garrison in the future.
Song Liyun brought out several large meat buns from the kitchen and immediately saw Song Zhenping standing in the front yard with his horse, seemingly lost in thought.
Juqingma stood behind him impatiently stamping its hooves, its mouth constantly nibbling at Song Zhenping's hairband, tearing the perfectly good hairband to shreds.
Song Liyun was both amused and annoyed, and couldn't help but call out, "Brother, what are you daydreaming about again?"
Song Zhenping snapped out of his daze and quickly tried to make conversation.
"Hey! What's this? Yun'er, is this the cardboard box you were talking about? Wow! You actually made it!"
Song Zhenping led the horse back to the backyard and began examining the small cardboard box with great interest.
It's smooth and beautiful, and it can be folded up to save space.
"Hahaha! Yun'er, you're amazing! You can actually make things from the Heavenly Book!" Song Zhenping's eyes were full of surprise and envy.
Xiao An nodded vigorously beside him: "Yes, it can be done!"
He made spicy rabbit heads yesterday, and today he made braised rabbit cubes following the recipe. It will be ready to serve in a little while.
He and Black Gold have both tried it, and it tastes just like the one his second sister makes—it's incredibly delicious.
Song Zhenping put down the cardboard box and said to Song Liyun, "Yun'er, starting today, read 'Common Vegetable Planting Techniques' to me again."
"Okay!... Ah! So much to read again?" Song Liyun was about to agree when she was suddenly dumbfounded.
The planting techniques book is so thick. I've already read through the crops that Wu Chao mentioned, and now I have to read it again... It's so boring!
"Just once!" Song Zhenping pleaded.
Xiao An stood beside him, biting her lip and blinking her eyes, looking thoughtful.
After dinner, it was study time again. Xiao An started looking at the recipe with great interest, while Song Liyun slowly read "soybean planting" to Song Zhenping.
Song Zhenping listened attentively, and every now and then he would ask Song Liyun to point out the words on the pictures to him.
After reading the entire text, Song Liyun was already drooping her eyelids and slipped back to her room to sleep.
After Xiao An fell asleep, Song Zhenping poured some water from the teapot on the kang table, dipped his hand in it, and began to trace the words he had written down that day on the table: "soybeans... 3cm interval..."
After finishing writing, he took out another piece of paper that Song Liyun had used, pointed to the Wu Chao characters on it, and silently read it aloud.
If Song Liyun were to see this, she would be extremely surprised.
Song Zhenping is learning two languages at the same time.
