Chapter 20 Abutilon and Tussah

Commonly found on roadsides, wastelands and fields.

The bark fiber of this species is white and shiny, and can be used to weave textile materials such as sacks, ropes, and hemp shoes.

The oil content of the seeds is about 15-16%, which is used for making soap, paint and industrial lubricating oil; the whole plant can be used for medicine.

Seeds (abutilus pockmark): bitter, flat.Clearing away heat and promoting dampness, detoxification, removing nebula.For corneal clouding, dysentery, carbuncle.

Root (abutilum root): used for dysuria and dysentery.

Whole grass or leaves (abutilus): bitter, flat.Detoxification, expelling wind.For carbuncle sores, dysentery, otitis media, tinnitus, deafness, joint pain.

He Qing laughed happily and was not in a hurry to make paper, "Let's use these leaves first."

Abutilon can only be harvested in autumn. It is too wasteful to cut it off in summer.

Speaking of summer, women are beginning to be like men, He Qinghuan looks at the swaying in front of his face every day, swaying past

I can't bear it.

"You have feelings for them?"

"No."

"Then just be naked, it's so cool." Bai Fucheng didn't mind, he's been here for three years like this, it's nothing.

"Do you know what civilization is?"

"Civilization must first eat, and then think about things."

He Qinghuan frowned, what can I say to this kind of reckless man?

"Qing'er, Qing'er, don't go. I think men and women should be equal.

It's so hot, men can be shirtless, why can't women?

Isn't this engaging in inequality between men and women?

Don't women also want to be cool? "

He Qinghuan said: "I will find something that is comfortable, cool, and beautiful, and make clothes for women."

Give Bai Fucheng: You don't have to give me the look of sophistry.

"Men also have to wear vests, okay?"

gone.

He Qinghuan took ten students to find suitable raw materials for papermaking nearby, because the problem of toilet paper was solved, but the problem of writing still needed to be solved.

He has named students in ten of his majors.

The girls all took the surname Bai, followed by Bai Fucheng's surname, from oldest to youngest: Baijian, Bai Fushu, Bai Xiaocheng, Bai Shuya, Baizhi.

Boys are the names of ancient directions and marching formations: Qinglong, Baihu, Suzaku, Xuanwu, Yinglong.

It can be seen from the name that he expects these students. He hopes that girls can be independent, achieve achievements in medical culture and education, and retain the characteristics of patience and tolerance unique to women, gentle and firm.

I hope that all the boys not only have the military ambitions like Bai Fucheng, but also be considerate and considerate to care about the suffering of others.

In short, he and Bai Fucheng set extremely high expectations on these children, so the requirements are more comprehensive and strict.

In addition to dealing with practical affairs with him every day and learning various practical knowledge, I also systematically learn to write at night.

Starting from real life, everything is based on life, first learn daily necessities, and then learn animals, plants, and natural phenomena.

Be sure to use it as soon as possible after learning it, not the fake Taoism of fake Dakong.

While walking, I told the students to look for plants with long fibers, toughness, and no smell, and to grow them in large quantities.

In addition to bamboo, there are also these virgin forests all over the mountains, using wood?

Not saying it's impossible.

The new branches and side branches of trees that have never been pruned can be pruned, and the main body still exists.

There are also places that are too dense and need thinning, which is conducive to growing into large trees.

Just use wood.

A4 paper cannot be produced, and yellow paper can temporarily solve the problem.

Also find a stagnant pond in the lower reaches of the lake for retting raw materials.

One: felling wood, soaking in the pond.The lignin in the wood will oxidize over time, which is why the paper turns yellow, so the most preferred paper is bamboo.

This time alone will take 100 days. It seems that paper cannot be made this year?

Still give it a try.It's always a matter of experimenting, and you'll never know until you do it yourself.

Two: Boil bamboo or wood and lime for eight days and nights under the action of lye

Remove resin, lignin, grease and other impurities.Take it out, rinse it in clean water, and steam it in a lime pot.

Three: Put the boiled raw materials in a stone pestle and pound them into a velvet shape, then add water to dilute them into a pulp suspension.

Fourth, the hardest work begins. Use a very thin rectangular wooden framed bamboo curtain to pick up the pulp from the pool, and shake the pulp evenly to every corner, otherwise the thickness will be uneven.

Can not be too much or too little, too much, the paper is too thick to waste pulp, too little paper is too thin, easy to break.

This requires constant tempering and patience.

[-]. Pour the bamboo curtain coated with paper pulp on the cardboard, gently remove the bamboo curtain, and the pulp will remain on the cardboard. In this way, the paper film is formed layer by layer.

Then press it with a heavy object to squeeze out the moisture in the paper film.

Six: Peel off the formed paper one by one, stick it on a smooth surface, wall, and dry.

There are natural drying methods, and baking methods, repair the sandwich wall, there is a flue inside, heat it up, paste paper, and it will dry quickly.

Take it off and put it away, and cut it into suitable size.

Now that the problem of raw materials has been solved, taking advantage of the three months of retting, a water mill can be built in a place where the water flow is turbulent and the drop is large. Not only can it pound pulp, but it can also pound dried sweet potatoes, dried meat, and everything else.

When something is pounded, it tastes better, the taste is more delicate, and it is better absorbed. It is especially suitable for the elderly and children with bad teeth.

While it was still dark, He Qinghuan drew the mechanical schematic diagram of the water reel by the fire, while An Dong watched from the side.

Father has already explained that if you have nothing to do, you can watch what the envoy is doing next to the envoy. Those are skills, and after a long time, even if you learn a little superficial, it is enough to walk sideways in this world.

An Dong said: "But I think Dad is the most powerful. He can hunt and kill saber-toothed tigers."

Bai Fucheng said: "Your father is a martial artist, and he is good at fighting. If he talks about making the country rich and the people strong, he is still an envoy of God."

At this moment, He Qinghuan was drawing while explaining to An Dong that this is a gear, this lever, and this is a fan blade. When the water flow hits the fan blade, it will drive the gear to rotate, and then the steering gear will drive the lever up and down. sports.

Then we put wood and bamboo that are not easy to be crushed here, no need to use force, just watch and take care of it.

When we have rice in the future, we can also make water mills, grind grain, and pound grain.

What is food?

Food is the seeds of the crops we grow. Although they are small, they are plentiful and healthier than eating meat alone.

Even many people only eat food and vegetables, and can live well without eating meat.

Don't eat meat?How to live?An Dong didn't believe it at all.

You will find out later.

The child ran over and held a handful of pale yellow eggs for He Qinghuan: "My lord, you see, I caught such an egg, can I eat it?"

He Qinghuan was pleasantly surprised by the light of the fire: "Where did you find it? Are there many?"

The children are called pottery pots, because the tribe recently fired pottery, and many children without names were given official names by adults.

This child is called Gaoshan Taoguo, and there is a younger sister named Taowan.

Because the God Envoy drew Juan pottery urns, pots, vases, pots, and cups in various shapes, so the tribe has been full of voices calling all kinds of pottery recently.

Just like the previous generation, there were so many names such as Chunshan, Chunshui, Chunshu, Chunhua, and Chuncao.

Seeing that the pottery pot made Master like it very much, he was also very happy: "In the woods over there, there are a lot of knots on the trees. The leaves are all bare. Emma said this is not delicious, and I never pick it."

"Well, Taoguo, take me there tomorrow, and call a few children with you."

Tao Guo happily agreed, and ran to invite the children to pick the Maoguo tomorrow with God Envoy.

Holding tussah cocoons in hand, I have already started to think about how to process silk and clothes with tussah silkworms.

The fibers of tussah silkworms are thicker than those of mulberry silkworms, generally as thick as human hair.

It can weave medium-thick silk fabrics.Its current advantage is that tussah silkworms can be raised in the wild on oak trees, also called oak trees, and artificially guarded so as not to attract natural enemies, which is less troublesome than silkworm breeding.

Moreover, the fluffiness and warmth of the quilt made of tussah silk are better than those of mulberry silk.

Acid and alkali resistance, high toughness.

Moreover, like silkworm chrysalis, tussah silkworm chrysalis is also edible, and it is much larger than silkworm chrysalis.

Because of its strong waist and strong kidneys, it is very popular among men, and it is a luxury item in the night market.

This geographical dimension is exactly the dimension of tussah silkworm production. In my own era, tussah silkworms were very popular in the market.

Of course, there are also disadvantages, that is, it is not easy to reel silk, because tussah cocoons are denser than silkworm cocoons, water is not easy to penetrate, and the cocoon layer is also tighter and more elastic. The degree of glue is heavy, so it is difficult to dissociate the strands.

With good management, spring and autumn can be harvested in a year. Now that spring has been harvested, let's see if we can artificially stock them once in autumn.

A good tussah silkworm cocoon can grow to nearly five centimeters, and a small cocoon is four centimeters, which is larger than ordinary silkworms.

Pass the silkworm chrysalis to the witch doctor: "Keep it well, and wait for him to come out by himself."

When the feathers become moths, they can be kept in oak trees to take care of them.

Let women or children learn how to raise tussah silkworms, mainly to drive away birds and beasts, and pick them off when they are mature.

The witch doctor had a sinister smile: Hehe, Lord God Envoy has found something good again, no one can take it away from me.

Turn around and hide in your own basket.
