Lao Mu is a carpenter and can tell the purpose of the board in his hand just by touching it, but now he is dumbfounded: What is cardboard? What can it be used for?
Han Ming also wanted to see what he could do with cardboard, and urged Carpenter Mu to get started quickly.
Due to space and technical problems, Song Liyun could only make corrugated cardboard that was fifty centimeters long and thirty centimeters wide.
The pulp uses binders made of bark fiber and reed stems, acorn starch, and millet flour. Clay is added to the slurry to increase hardness and viscosity.
To be honest, the quality of the paper produced is really good.
If there are no conditions, create conditions.
There is no machine scroll core. The center of each cardboard is a small paper roll rolled out by hand as the core, and the two sides are pasted with hard paper and glued together.
In this way, each board is not only strong, but also has smooth and delicate paper surfaces on both sides.
If necessary, it can also be spliced into large sheets of cardboard.
Carpenter Mu had no experience in making woodworking with paper, so he followed Song Liyun's instructions to make cardboard boxes using lamination and mortise and tenon joints without using wooden nails.
It's just that this cardboard box is a little strange. It has no lid and is only covered by four movable pieces of cardboard.
It's so light when you lift it up, and it won't break even if you drop it on the ground.
And as long as you take out the bottom board and fold it in three or two, the sturdy cardboard box will turn into a stack of cardboard like magic.
When it is opened again, it becomes a strong cardboard box that can be used over and over again.
Han Ming clicked his tongue in surprise.
Even though he was personally involved in the entire production process, he still couldn't understand how those tattered pieces of dead grass bark could be turned into boxes.
And as long as the box is filled with things, it can still withstand the trampling of a man like him.
This... is really amazing!
In April, at dusk, the town of Ruijin was already full of fireworks. Farmers who were finishing their work in the fields outside the town were walking together and talking to each other about the drought situation in the soil this year.
It's already April, and there hasn't been a thorough spring rain yet.
Broken Golden Guard dropped the water-breaking stone in the bridge hole under the wall, and now the Huangsha River is filled with water.
There is no problem with watering the land outside Suijin Town. You only need to dig a ditch to divert water into the land. Every piece of land is fertile land with guaranteed harvests despite droughts and floods.
Since returning from Pingyang Mansion, Song Zhenping did not plant coarse grains as he had planned before. Instead, he used the rice he bought from Pingyang Mansion to cultivate rice seedlings, preparing to plant this large area of land into fine grains.
The sown spring rapeseed seedlings are also growing.
The germination rate of the seeds returned to nature is much better than that in the greenhouse in the backyard, with more than a hundred plants. Plus the two rapeseed plants in the backyard that are about to bloom, there can be some harvest, and he is not worried that the fairy seeds will become extinct.
People who farm love to come and see the Song family's land.
Because Song Zhenping’s planting methods are quite different from theirs.
What is the spacing between rows and nests, what temperature of soil is used to raise seedlings, and what temperature is used to raise seedlings. Many words sound like bibles.
Song Zhenping doesn't hide his secrets, he tells everything he knows, but... not many people are willing to listen to him.
Everyone is used to growing corn, corn, sorghum, and potatoes as the staple food, and then growing peanuts and sesame to extract oil, which is enough for the family.
Fine grains such as wheat and rice require high technical requirements, and if you are not careful, the harvest will fail, so they try to plant as little as possible.
In addition to rice, Song Zhenping also grows a large amount of sesame seeds, peanuts and broad beans, which Yun'er said can be used to extract oil, mainly because the family is accustomed to using more oil for cooking.
In the evening, when Song Zhenping and Ju Qingma entered the courtyard gate, they were startled by two square-headed monsters rushing towards them.
Xiao An and Hei Jin were running around in the courtyard each carrying a yellow cardboard box, just like the big-headed gods who used to visit the village during the Chinese New Year.
"Xiao An, if you can't touch the ground like this, be careful of falling!"
When Xiao An heard his brother's voice, he rushed over with a diagonal stab and almost ran into Ju Qingma.
Song Zhenping was so frightened that he hurriedly caught him.
Xiao An took off the cardboard box on his head and said to Song Zhenping with a smile: "Brother, are you tired?"
Although Dai Langzhong's medicine is expensive, the ointment is very effective. He has been taking it for nearly a month after returning from Pingyang Mansion, and Xiao An's speech has become fluent and clear.
Song Zhenping touched his head: "You're not tired!"
It was spring plowing now. Although he worked in the fields every day, he was not hungry and had plenty of strength. It was very easy to cultivate fifteen acres of land in Xiaoshi Village.
Moreover, when there is more work to do, the sergeants from the guard station will come to help.
The seeds have already been planted in the ground, and all he can do now is to see how the seeds germinate while he is grazing.
Song Zhenping frowned when he thought of the sergeants at the guard station: Today another sergeant wanted to propose marriage to Yun'er, and he asked General Xiao to be the matchmaker.
Although Mr. Xiao only mentioned it slightly, he still refused!
In the past half month, I have rejected five.
Some people want to marry into the family, some want to marry a wife, and some directly offer a betrothal gift of ten taels of silver...
Among these people was Wang Qi, who also refused.
well!
I am afraid that I will offend all the people in the guardhouse in the future.
Song Liyun took out several big meat buns from the kitchen and saw Song Zhenping standing in the front yard holding a horse, wondering what he was thinking.
Ju Qingma stood behind him and stamped her hooves impatiently. Her mouth kept chewing on Song Zhenping's hair tie, which was pulled to pieces.
Song Liyun was so angry and funny that she couldn't help shouting: "Brother, what are you doing?"
Song Zhenping came to his senses and quickly found something to say.
"Hey! What is this? Yun'er, is this the cardboard box you were talking about? Oh! It's really made!"
Song Zhenping took the horse back to the backyard, took the small cardboard box and looked through it fondly.
It's smooth and beautiful, and can be folded up so it doesn't take up any space.
"Hahahaha! Yun'er, you are so awesome! It turns out that you can make everything in the Book of Heaven!" Song Zhenping's eyes were full of surprise and envy.
Xiao An nodded vigorously beside him: "Yes, I can do it!"
He made spicy rabbit heads yesterday, and today he made braised diced rabbit according to the recipe, which will be ready to eat in a while.
He and Hei Jin have already tasted it, and it tastes the same as the second sister's. It's delicious.
Song Zhenping put down the cardboard box and said to Song Liyun: "Yun'er, from today on, read "Common Vegetable Planting Techniques" to me again."
"Okay!...Ah! Do you need to re-read so much?" Song Liyun was about to agree, but was instantly dumbfounded.
The planting technology is a thick book, and I have already read it about the crops that were available in the Wu Dynasty, and I have to read it again...it's so boring!
"Just once!" Song Zhenping begged.
Xiao An was biting his lip next to him, blinking his eyes, looking thoughtful.
After the meal, it was study time again. Xiao An began to read the recipes with gusto again, while Song Liyun slowly read "Soybean Planting" to Song Zhenping.
Song Zhenping listened attentively, and from time to time asked Song Liyun to point out the words on the pictures to him.
After reading one article, Song Liyun's eyelids were already clenched and she slipped back to her room to sleep.
After Xiao An also fell asleep, Song Zhenping poured some water from the teapot on the kang table, dipped it in his hands, and began to trace the words he had written down today on the table: "Soybeans... 3cm apart..."
After finishing writing, he took out a piece of paper that Song Liyun had used, pointed to the Wu Chao font on it and read silently.
If Song Liyun saw it, he would definitely be surprised.
Song Zhenping is learning two languages at the same time.
