I do research in ancient times

Indigenous fertilizer.

As I said before, some of the customized fertilizers for potatoes, sweet potatoes, and corn are the same.For example, the active ingredient in phosphate fertilizer is phosphorus pentoxide, which needs to be obtained by decomposing phosphate rock.There are two main decomposition methods. Acid method phosphate fertilizer is made by decomposing ore with sulfuric acid, nitric acid, and hydrochloric acid; thermal method phosphate fertilizer requires high temperature, adding silica, dolomite, coke, etc.No matter which one it is, the basic raw materials need to be prepared chemically, and the current technical conditions are not up to large-scale production.

However, the industrious and kind-hearted people of the flower-growing country have full of farming skills early in the morning, and they can always think of some black technology and earth-shaking methods to replace large-scale industrialization.

It is still this phosphate fertilizer, Ning Fei has seen the practice of soil compound fertilizer recorded in literature.

Crush superphosphate and sieve it, mix it with human urine in proportion, pile it into a conical shape, seal the outer layer tightly with 10 cm thick mud, and pile it up for a week before use.Soil nitrogen, ammonium and phosphorus compound fertilizer is obtained by simply steaming raw animal bones, removing part of the fat, and crushing. It contains a large amount of nitrogen and phosphorus.Soil ammonium sulfate needs to be mixed with human urine, plaster of paris and water, and sealed for 3 days.Soil ammonia water requires a lot of fresh cow dung, which is not easy to get, but the remaining soybean powder and plaster powder are not rare things. After gathering the cow dung, seal it for [-] days, and then dilute it three times with water. The fertilizer efficiency is higher than ordinary ammonia water.

Ning Zaozi thought about it, and felt that animal bones are not difficult. He originally planned to start a breeding business in Wupu. Pork bones, chicken bones, duck bones, sheep bones or foot bones.Human urine is more troublesome.At present, there are less than 100 people in Wubao, and there are many places where human urine is needed. This output is not enough to irrigate the land at the bottom of Niubei Valley!

I have to figure out a way to get some human urine from somewhere...

Of course, excessive urination requires a large number of people, and there are a lot of people in Ding'an City. Merchants from all over the world gather in the city, and it's hard to know how much excrement will be produced in a day.

However, it is too conspicuous to produce fertilizer raw materials from Ding'an City, and some people will always ask them why they want this thing, and it is difficult to explain it at that time.

Ning Zaozi fumbled his abacus a few times, and finally he decided on his brother Mu Ye.

The Feng family has soldiers, a black armor army, a barracks, and frontier cards. How many troops does it take? !

Some people want to eat, drink, and scatter. Instead of letting them be released freely in the world, how about giving them to Mozong to make soil and fertilizer? !

The more he thought about it, the more he realized that it was feasible, the abacus in Ning Zaozi's stomach was crackling, wishing he had a phone at hand, so he could harass his brother Mu Ye to discuss the fattening business.

However, things cannot be said directly.

He is pure and innocent, ah bah, Mo Zong's juzi with a clear wind and bright moon, if he finds Brother Mu Ye for this little shit, it will seem that he is so worthless as Ning Juzi!

You have to find a way to take advantage of it, and at the same time show yourself to be upright and righteous. Brother Muye is a clever little guy, but he has to keep accounts for his debts. If he saves too much, he might sell himself repay.

The last time he tried to use cement to deduct the grace of rescue, he was declined...

After pondering over and over again, Ning Zaozi decided not to take any risks.

If you want to take it, you must first give it.If he donated a place of reincarnation of five grains to the frontier army, and then provided regular replacement and cleaning services, would he be able to openly harvest natural fertilizers? !

Of course, this place of reincarnation should also be ingeniously built, the dry and wet should be separated, and the fertilizers should be distributed in different ways. Users must feel the atmosphere and details of Mozong craftsmen.

This thing can be regarded as the work of the carpentry class. As a product manager, Ning Zaozi is only responsible for providing the construction of the product framework, the description of user needs, and the basic functions that he wants to achieve.

The rest of the parts, of course, are filled and designed by members of the carpentry class, and then delivered to the blacksmith workshop for construction and customization, and then sent to him for acceptance.

"Probably like this, make something like a chair on it, and the back part should be wider to provide running water for washing, but not too much, because too much water will dilute the urine we need, and it is not easy to master the later stage fattening ratio."

Early the next morning, Ning Zaozi called several members of the carpentry class to his yard for a breakfast meeting.Looking at Juzi, who had dark circles under his eyes but was in high spirits when he talked about fattening, everyone felt more and more that the soy milk with buns in their hands was not easy to swallow.

Just...why?Why did Jizi suddenly want to build a toilet? !

I also said so many requirements, there must be a design for ventilation and flushing, isn't the latrine just a place to defecate and pee, the construction is so comfortable, what should I do if I squat in it and get out?

However, when they thought about the recent news that the sect would have all members farming, everyone felt at ease again.

Feces and urine are all fertilizers. The old farmer Shiliu of the Zongmen gave a class to everyone last night, and the first thing he talked about was fertilizers.

"Livestock dung, manure, silkworm dung, bone juice, plant ash, old wall soil, these are all fertilizers."

Old man Liu stood on the table in the small conference room, looking at the dark crowd below, his chest was raised high.

"Cultivation consumes land, and it must be fallowed after a certain period of time, otherwise the land will be exhausted and no more food will grow."

Ning Zaozi, who was sitting in the first row, was the first to raise his hand to ask a question.

"Excuse me, Mr. Liu, may human excrement be used as fertilizer?"

Old man Liu liked hearing people call him Mr., so he nodded immediately.

"Naturally, it is possible! Human dung is grain, meat, fruits and vegetables that have not exhausted their energy, but first-class dung, and the dung field is not damaged."

"Oh."

Ning saw the answer, and raised his hand to ask again.

"Where's the man's urine?"

Urine?

Old man Liu scratched his head.

"That's useless. The essence is in the feces, not in the soup, and the urine is useless."

It was these words that led to the birth of Yechao's first mobile toilet with wet and dry separation!

Ning Zaozi's calculations are very clear. People at that time valued dry ingredients, and no one cares about the watery part, which has always existed as a supplementary fertilizer.

The frontier army also has farms, so they must be aware of the usefulness of dry materials, and it is almost impossible to deduct manure from Brother Mu Ye.

But he would rather see saws, he is such a man who doesn't take the usual way, he doesn't want dry materials, he just likes parallel imports!

Because there is no conflict of interest, as long as the distribution of the spoils is clear, I believe that Brother Mu Ye will not care so much with him.

"So, the center is the separation of dryness and wetness. We only need to pee, not shit. Is everyone clear?"

"We have to use this toilet ourselves! After the spring plowing begins, everyone is not allowed to defecate in the wild. You must go to a toilet with a dry and wet separation function. Violators will be fined three buckets of urine!"

With an order, everyone scattered in fright. They didn't understand why their style changed after a year.

Weren't we all engaged in "noble" technologies such as cement, textiles, and iron smelting in the past, why did we suddenly focus on manure? !

Doubts are doubts, but Juzi's orders must be obeyed.

The mobility of everyone in the carpentry class was excellent, and they quickly created a prototype based on Juzi's description. Not to mention, it really looked like a flush toilet.

Of course, the key point emphasized by Jizi has not been forgotten.Through the separation and filtration of the lower toilet, the woodworking class successfully realized the separation of dry and wet.

It’s just that the liquid can go directly into the storage tank below, but the dry product needs the user to manually pull out the bar valve and overturn it into an independent storage tank.

"very good!"

Ning Sawzi was very satisfied.

He said that this group of carpenters are good seedlings learning mechanics, right? !Take a look at this trick, it couldn't be more suitable to use it on the toilet!

After modifying several details, Mo Zong's version of dry-wet separation manual mechanical collection toilet was finalized and sent to the blacksmith workshop to produce the prototype.

Now all the staff in the blacksmith workshop are busy forging Mo Dao.After the Feng family determined the plan, Ning Fei specially customized a set of technological processes according to the Feng family's requirements to ensure that there would be no obvious difference in the quality of Mo Dao produced by Mo Zong at any time, under any circumstances and with any personnel.

In the era without machinery and industry, it is not easy to do this, especially the Feng family's batch of knives is in a hurry, and they must be delivered before the spring thaw, so the simplicity of the process becomes extremely important.

Recently, the blacksmith workshop has been training young apprentices, teaching them how to use blast furnaces to make iron, how to distinguish the color and temperature of molten iron, what skills they need to master when pouring steel, and the precautions for making threads.

It is not easy to master the whole process in a short time, but it is not difficult to concentrate on learning a part of it.The blacksmith's workshop divides the process standard process formulated by Juzi into several parts, and each person is responsible for one of them, which is much faster than before.

In the past two days, the first batch of Modao that is about to be delivered has been completed and is undergoing quality inspection. Everyone in the blacksmith workshop has nothing to do, sitting in the workshop and chatting.

When Clay went to deliver the blueprints, what he saw was a scene of people hanging their feet together.Because of work, the bad habit of drying the feet in the blacksmith workshop can no longer be changed. Ning Fei can only distribute enough light powder regularly as condolences, which is very popular.

So even though there was a smell now, it was not intolerable. The child just frowned and walked into the yard of the blacksmith workshop.

As soon as they saw him coming, all the blacksmiths immediately knew that they were coming to work, and they all looked at the child expectantly, hoping that they would be overturned by Juzi today.

The last time I made a hot pot, Juzi chose Liu Tie.Although Jizi also said later that everyone can help, there is still a big gap between helping and the main force!

Let’s just say that Liu Tie is lucky, he stayed after offending Juzi so much at the beginning, and now he has turned around in one fell swoop, learned a lot of skills from Juzi, and has become the main craftsman in the blacksmith workshop, how can he not be envied? !

There is nothing wrong with the things made by Ji Zirang, just the hot pot last time... suck...

I can't think about it, my mouth is watering just thinking about it!

Jizi said that when the spring plowing is over, he will invite everyone to have a hot pot meal. It will be beautiful to think about it!

Seen by the group of tall and thick men, Clay felt trembling, took a step back vigilantly, and then handed Mu Donglai a roll of birch bark.

"Jizi said to let you see and build one, the sooner the better."

"okay!"

Mu Donglai was delighted.

If it is given to him, it means that he is still the man with the best technology in the blacksmith workshop. This recognition greatly satisfies Mu Donglai's vanity.

He lost to his apprentice Liu Tie in the last two times of casting knives, and was ignored by the family members when he returned home. He urgently needs to prove his ability by working.

Opening the birch bark, Mu Donglai frowned, and the expression on his face was rather indescribable.

This thing...is exquisite in workmanship, complicated in components, and uses mechanisms...

But no matter how refined, this is just a cesspit!

Mu Donglai scratched his head and didn't dare to ask the child, but there were uninterrupted question marks in his mind.

Clay, regardless of what was going on in their minds, simply repeated what Moko had said.

"This is a sample that is going to be sent to Ding'an City. It is still very tight to deliver it together with this batch of Modao."

"Because it's just a toilet, the materials don't have to be particularly good, ordinary ones are fine. The key is airtightness, and there must be no leaks. The things inside must be good things."

What?nice one?

Now, everyone in the carpenter's room was stunned.

Isn't this a shit pit?Although it is packaged in two tin cans, it is just excrement and urine. What kind of good thing is this? !
