The whole family of villains criticized her wildly, but the princess treated her with medical treatm

reed?

bamboo?

Or even bagasse?

Lu Jingyan was shocked and couldn't believe what he heard: "Your Highness, I have only heard of oak bark paper and the more advanced paper bark paper. Bamboo and reed are too hard, and bamboo is green, and sugarcane bagasse is Not to mention, that stuff can only be used as farm compost at best.”

There are only two ways to deal with sugarcane bagasse in Yunhuang Kingdom.

One is burning.

The second is to accumulate it with livestock excrement and human excrement to form a septic tank and make compost. When planting in the next spring, it will be spread into the soil.

As for paper making, it’s impossible, absolutely impossible!

Mu Tingxue continued: "Bulkthorn is a good thing. It grows quickly. In spring, you can pick the inflorescences to make vegetables and eat them. In summer, you can pick fruits to eat. In autumn, you can peel the bark to make paper. The remaining trunks can also be burned as firewood. The leaves can be used as food. Pigs, the sap can cure skin diseases, and the rhizomes and seeds can be used as medicine. The only bad thing is that the leaves have barbs."

Lu Jingyan nodded: "Yes, paper mulberry grows very quickly. But because its bark can be used to make paper, it has been bought up by aristocratic families, and the supply exceeds demand. It is now rare in the countryside."

Mu Tingxue said: "Paper is a very serious problem. If there is too little paper, it will greatly reduce the difficulty of storing and disseminating knowledge and information."

Papermaking workshops are basically owned by aristocratic families.

They also control the raw materials for paper making.

Even with the exception of the Central Book Engraving Workshop of the Imperial College, the rest of the private and family engravings were also controlled by this class.

The direct consequence of this series of operations is - cultural knowledge monopoly!

"Your Highness, these aristocratic families are smarter now. They know that if they openly resist taxes, they will go to jail. If they do not cooperate with the Ministry of Household Affairs to clear the land or conceal the land, they will be forced to liquidate. So when it comes to the lower levels of local villages and towns, they will be unable to record without paper. For the sake of excuse, just do the job half-heartedly, soak the mushrooms in cold water and do nothing, it’s just a tactic of procrastination.”

Lu Jingyan had a headache. "There are forty states, hundreds of cities, thousands of counties, and tens of thousands of villages in the country. If we conduct a household registration census one by one, there will not be enough paper available."

Mu Tingxue understood what he meant.

As the highest government agency responsible for the census of household registration and fields, the Ministry of Household Affairs has a fair amount of control over the state, but barely enough control over the counties. When it comes to villages and towns, it is basically beyond its reach. The shortage of paper at the grassroots level has greatly limited the census of fish scale albums.

Take a longer view.

The shortage of paper will also allow wealthy families to continue to monopolize knowledge unscrupulously.

She used to ask the Imperial Academy to help engrave books, but most of the books sold were sold to wealthy people such as nobles, nobles, clans, and officials. I couldn't get out of that circle.

"In this case, we can only make more paper."

"Could it be possible, as His Highness said, to be made of bagasse, bamboo, and reeds?" Lu Jingyan couldn't imagine it.

"of course."

Mu Tingxue had an idea, "Whose is the largest papermaking workshop currently?"

Lu Jingyan replied: "Li's papermaking workshop uses oak bark as raw material; Puyang's papermaking workshop uses papermaking bark as raw material. They are both leaders in the industry. These two companies also have their own bookshops."

Mu Tingxue knew what was going on.

Her Imperial City Academy is a welfare institution. Children can learn to read and write. Exercise books and books are distributed every month.

Coupled with the introduction of small blackboards and cheap chalk, paper money was completely eliminated.

"Let's build a paper mill in Imperial City. Making more paper will not only help clear the country's land, but also cultivate talents in large quantities."

Just do it.

Mu Tingxue is ten times more passionate about bagasse papermaking than ketchup.

Ketchup is just a food derived from white sugar, white rock sugar, and tomatoes. It makes the dining table of aristocratic families richer, but sugar cane paper is different. With it, it can even break the existing social hierarchy. Structure, with the spread of knowledge, the privileged class will face huge disasters.

The first thing she did was to go to Tang's Sugar Factory in Imperial City to inspect the raw materials for papermaking.

That is, sugarcane bagasse, the waste from sugar mills.

Before the acquisition and integration of Tang's Tangtang Liao, sugarcane bagasse was piled high, dirty, smelly, rotten and infested with insects, everywhere. Tang's original treatment method was to burn it intensively and burn it to ashes, then transport it to Tang's sugar cane fields and spread it as fertilizer.

When it burns, it can be said to be filled with smoke and dust.

It's like a big smog.

It is now the end of October. The growth cycle of sugarcane is seven months. Now it has been cut down and harvested. New sugarcane seedlings are sown in autumn and winter, fertilizing the land, entering the budding stage, and growing branches and buds.

When Mu Tingxue went to inspect the sugar cane fields, she happened to see truckloads of sugarcane bagasse being pushed to be burned.

"Stop! Stop burning!"

"Your Highness, these bagasses are used to burn fertilizer."

When Mrs. Tang heard that the eldest princess was coming, she hurried over from Tianlu and explained in person, "If it is not burned, it will pile up into a mountain and the rotten smell will be very unpleasant. It will not meet the clean environment standards you need."

The backbone of the sugar factory have all been beaten and know that His Highness likes cleanliness and hygiene.

"It's so eye-catching."

"It only takes two or three days to burn it." Mrs. Tang hoped that the eldest princess could take back her life. "Some sugarcane leaves and sugarcane peels are also in it. The burned plant ash can be used for fertilization."

“Sugarcane leaves and sugarcane peels can be kept for agricultural compost.”

Mu Tingxue ordered, "Keep all the bagasse. This princess will put it to good use."

Although Mrs. Tang nodded in agreement, she had doubts in her heart and muttered: "What else can you do with this bagasse..." It's just waste.

Mu Tingxue added: "To make fertilizer, there is no need to light a fire. You can use [-] catties of human and animal excrement, [-] catties of sugarcane peels and leaves, [-] catties of plaster of paris, and [-] catties of water. Mix them evenly according to this ratio. , seal it in an earthen kiln for ten days, and then fertilize directly.”

This is one of the methods of composting. “Sugar cane peels and sugar cane leaves can also be replaced with organic items such as straw, fallen leaves, and straw.”

Mrs. Tang was stunned: "May I ask, Your Highness, how to make this plaster of paris?"

This was the first time she heard about this wonderful method of making farm compost.

"It's very simple. It can be made with quicklime powder. Quicklime is added with water to slake mature gypsum. The slaking time is no less than seven days." It is a reaction in which calcium oxide is added with water to generate calcium hydroxide and release a large amount of heat.

Farm organic fertilizers can increase crop yields significantly.

In ancient rural areas, excrement and kitchen garbage were often poured into a dry well and allowed to ferment freely. Straws and fallen leaves could also be swept in. When fertilization was needed, they could be taken out directly from the dry well. use.
