"My secret recipe can increase the fertility of the land, so that the yield of crops on the land can be doubled to two per mu!"

When he heard this, Zhu Gaochi finally couldn't sit still, and he stood up and stared at the opposite wall.

"What?"

Zhu Di plucked out his ears and asked suspiciously.

"I heard you right, Jiang Xinghuo said that he has a way to make the land fertile and double the yield per mu?"

Zhu Gaochi stared at his father with wide eyes, and his face was full of surprise.

"Yes!"

Zhu Gaochi nodded seriously and said, "That's what Mr. Jiang said just now!" ”

"Haha."

Zhu Di bit a few times, then walked over, patted Zhu Gaochi's shoulder, and nodded with satisfaction.

"Good! Great! ”

"Mr. Jiang is really an immortal, if there is really this immortal recipe, doesn't it mean that the Ming Dynasty can grow more food, the people live a prosperous life, and the taxes collected by the state far exceed those of various dynasties in history? At that time, the national strength of the Ming Dynasty will be greatly enhanced! I will be able to fulfill my wish and defeat the Mongols once and for all! ”

Zhu Di's interest was very high, but Zhu Gaochi still cautiously reminded.

But just now Mr. Jiang also said that although the cost is not extremely high, but listening to the meaning of his words, the cost is still not low. It may be that large-scale production is not cheap, or large-scale production, and it cannot meet the needs of the whole country. ”

"None of this is nothing!"

Zhu Di interrupted his eldest son and waved his fist.

"As long as it is really proved that this immortal recipe can be made, I can ask the best and most professional people to do it, as long as it can make the land more fertile! This is a major matter related to the foundation of the country, and I don't care how much money I invest in it. ”

"I, I only need this immortal formula!"

Zhu Gaochi opened his mouth and guessed: "How much does the father think it costs to make this immortal formula?" Although the cost of the first time is definitely high, it is still necessary to calculate the cost, after all, this thing is to increase the fertility of the soil, if the cost of manufacturing is more expensive than the price of the land, it is really worth the loss. ”

Zhu Di thought for a while and said: "This kind of immortal recipe, the first time it is made, how can it cost thousands of taels just to purchase items, right?" Listening to Jiang Xinghuo's meaning, in the future large-scale production, the price may gradually come down. ”

"However, the first time it was made, the symbolic meaning was far greater than the practical meaning, as long as it can be made and proved to be effective in increasing the fertility of the land and increasing the yield of crops, it is already a great success."

Father and son nodded in unison at the same time.

It's normal for the first time to be a little more expensive.

When the next door heard this, everyone's breathing was also stagnant.

Is there really such a miraculous thing in this world?

As the top magnates of the Ming Dynasty, whether it is Li Jinglong, the Duke of Cao Guo, or Zhu Gaoxu, the second prince, they are undoubtedly well-informed, because their status is there.

But even Li Jinglong, who is both knowledgeable and likes to study 'knowing a little bit of everything', has never seen anything that can increase soil fertility!

In fact, for this era, agriculture is actually the most important thing and the foundation of the country.

Therefore, anything related to the 'increase in grain production', even if it may be just a rumor in the local newspaper, will be extremely valued by the imperial court.

After all, in these days, food is equivalent to life!

But what Jiang Xinghuo said can be artificially made, and it can also increase the fertility of the land, which is indeed something that Li Jinglong has never seen or heard of.

Li Jinglong thought that he had seen many strange things, but those were not comparable to what Jiang Xinghuo said in front of him, because it involved the land, the carrier of civilization.

Who would believe this kind of thing if they hadn't experienced it themselves.

But no matter what, since Jiang Xinghuo said it, it's worth a try!

And at this time, Yuan Hui, who had changed into clean linen clothes today, suddenly asked.

"Does this secret recipe really exist? Or rather, are you willing to take it out? ”

"Yes, I'm willing to take it out." Jiang Xinghuo shrugged his shoulders and said, "I can guarantee that the secret recipe is definitely effective. ”

"Is that true?" Li Jinglong exclaimed.

Zhu Gaoxu rubbed his hands excitedly and asked, "If this can be done, what does Mr. Jiang want?" Money? Beautiful concubines? Although. ”

"Hahaha" Jiang Xinghuo couldn't help laughing, "Do you think that if I want to, there will be a shortage of gold, silver and beauties in Daming?" ”

Zhu Gaoxu scratched his beard, and he was also a man.

If what Jiang Xinghuo said before is true, then Japan's gold and silver mountains, isn't it enough to spend a lifetime just picking up a bit?

What's more, with Jiang Xinghuo's talent, he is known as "Xiao Liuyong" on the Qinhuai River, and no matter how many prostitutes recommend themselves to the pillow seat, they can't get a song, it can really be described as "Jiang Lang's handsome reward, cardamom word worker", how many beauties don't you want?

Li Jinglong said: "Money and women are naturally the lowest level, how can a talented person like Jiang Lang lack women?" ”

"So what does Mr. Jiang want? If he is released from prison next year, Jiang Lang should always live, and we have nothing to say about the price at which this secret recipe wants to be sold. Li Jinglong asked confidently again.

"I don't need anything."

Jiang Xinghuo smiled at the surprised gazes of several people and said indifferently.

"If there is, it is a thought to save the people."

Li Jinglong looked at Jiang Xinghuo's young and handsome face, and was a little stunned for a while.

is obviously a gorgeous character who should be "the dream of Qinglou is so difficult to be affectionate", how can it be such a contrast.

At the same time, Yuan Heng secretly said in his heart: "No wonder this Jiang Xinghuo is so fateful, it seems that he is entangled with countless people, and he announces this thing that can be called an immortal prescription for free, this mind, it is really not comparable to us." ”

"Mr. Jiang, how can this kind of thing that increases soil fertility be made?" Zhu Gaoxu asked.

"The principle is very simple, of course, in this era, even if the product of the secret recipe is made, even if the cost is not extremely high, it is destined to be used only in a very small range in the way of 'experimental field', and it cannot be promoted to the whole country."

Jiang Xinghuo added a prerequisite.

"In the same way, I didn't make this thing for large-scale promotion, just to let you know how big the gap between different fertilizers and the current manure is to improve the yield of food crops!"

"Something that has been promoted on a large scale is another kind that has a similar effect to this, but it is not available for the time being."

"Understood."

Li Jinglong nodded and said, "In other words, Jiang Lang has other methods that can be promoted on a large scale, and this secret recipe is just said to be able to be made now, let's see a similar effect first." ”

"That's what it means." Jiang Xinghuo agreed with Li Jinglong's statement.

"And what about the first step? What is needed? Zhu Gaoxu asked again.

Jiang Xinghuo looked at Yuan Gong, who was dressed in sackcloth and had white hair.

"Step 1. An old Taoist priest who can do alchemy is needed. ”

Looking at everyone's eyes, the corners of Yuan Hui's mouth pulled a difficult smile.

"Isn't it okay to be small?"

Jiang Xinghuo shook his head and said, "The small one is not good, because this thing to be refined is a bit dangerous, and the average old person can prove that he has successfully practiced until now, and he has not been burned to death by this thing, and he is a journeyman." ”

Yuan Heng's face suddenly showed a strange look: "This ...... Is there still a life in this alchemy? ”

"It's not alchemy."

Jiang Xinghuo solemnly corrected.

"—it's chemistry!"

"I don't care what it's called, but this recipe, the old man is very curious."

Although Yuan Heng said that he was over sixty years old, he was well maintained, and at this moment he was staring at Jiang Xinghuo with blazing eyes.

Yuan Heng had never seen such a secret recipe to increase soil fertility, and he had never even heard of it, so he couldn't help but feel itchy.

"So what kind of pill does it need to be refined?"

Jiang Xinghuo corrected again: "It's not that you need to refine the pill, but you need to refine the green alum." ”

Li Jinglong and Zhu Gaoxu knew each other and were stunned.

Copperas?

What is alum?

Can you eat it?

But when Yuan Heng heard this, he looked abrupt.

Li Jinglong looked at Yuan Heng and asked, "What exactly is green alum?" ”

Yuan Jue explained: "Green alum is a kind of ore, the new mine cave has not seen the wind, the color is like glass, burned with charcoal, the alum boils out, the color is red like gold juice, and when the juice is exhausted when boiling, the color is like yellow dan." ”

"In other words, it's a transparent ore that turns green when the wind blows, and then burns into juice and can condense?" Li Jinglong probably understood.

"Yes." Yuan Jue nodded and said, "This is the main material of the Three Immortal Pills of Taoism, and it is also widely used in other pills, and it has been known to alchemists since the end of the Han Dynasty. ”

"Can you refin?" Zhu Gaoxu asked curiously.

"Absolutely."

Yuan Hui said with some pride: "The porcelain pot is not corroded, it will melt when it is burned, and it will be fixed when it is extinguished, as long as you are careful, it will not be melted and burned skin, and the decay has been refined for I don't know how many years." ”

"That's good, the first step is to solve the problem of an old Taoist priest who can do alchemy." Zhu Gaoxu turned his head and asked, "Mr. Jiang, what about the second step?" ”

Jiang Xinghuo pondered for a moment.

It really needs to be pondered, because he has to think about how chemical fertilizers can be produced in the laboratory in this era.

If you want to produce chemical fertilizers on a large scale in Daming, it is absolutely impossible!

You must know that even if it is half a page of 20 in the world, China cannot produce chemical fertilizers on a large scale, and the North Stick next door, even if it is a mushroom bomb, still cannot produce chemical fertilizers on a large scale on its own.

Fertilizer is two sides of the same coin.

The difficulty is that if you want to make your own nitrogen fertilizer.

Then it is necessary to obtain a source of nitrogen, which is ammonia.

Before the industrial age, there were only two ways to obtain nitrogen from farmland, lightning nitrogen fixation with a small probability of instability and biological nitrogen fixation, that is, distiller's grains, sugar residue, bean dregs, oil residue, etc., but unfortunately, ordinary farmers engaged in monolithic production could not obtain these biological nitrogen stably.

However, if you want to make industrial ammonia, you must face two difficulties.

The first catalyst, this thing can't be rubbed by ordinary people's hands, and Jiang Xinghuo can't do it, even if he worked as an apprentice and designer when he participated in the industrial salvation of the country in the sixth life, and opened a few factories by himself, it doesn't mean that he can do everything.

The second high-temperature and high-pressure resistant equipment, which is even more terrifying, the steel used for this equipment is the same as that of a submarine, in other words, when can you point out a series of pre-technology trees of submarine steel to make a device for synthesizing ammonia.

The reactor for ammonia synthesis needs to withstand a high pressure of more than 10Mpa at a high temperature of hundreds of degrees, well, that is, about 100 kilograms of pressure per square centimeter, and it needs to continue for several years without deformation.

The problem is, you can make submarine steel, and this special meow is not the Ming world!

Of course, in addition to synthetic ammonia, there is a simpler and lower way to obtain ammonia.

- That is the soil method of coking.

The simplest thing is to pile a pile of coke on the ground, and then use the soil to cover a long earthen stove that looks like a grave on the side, and light a fire to start refining.

If you are particular about it, you will build a special coke oven.

The coke oven is highly compatible with the kiln.

Not to mention that it is now the Ming Dynasty in 1402, it is to travel to the Eastern Jin Dynasty in 402, and this thing is all casually.

Because coking coal itself contains nitrogen-containing heterocycles, in the process of coking, these ammonia will float out in the form of gas, mixed in the gas, only need to collect these ammonia with liquid, and then let the liquid dry and solidify, you can obtain nitrogen fertilizer containing solid ammonia.

Of course, this kind of conversion is inefficient and cannot be promoted on a large scale.

Jiang Xinghuo's intention is not to promote it on a large scale, but to let them understand the amazing effects of chemical fertilizers while cultivating a little bit of scientific awareness.

Jiang Xinghuo never envisioned a large-scale promotion of chemical fertilizers, and for a reason.

Chemical fertilizers, for the current Daming, are not necessarily a good thing.

Because the application of chemical fertilizer has not undergone long-term experiments, it is difficult to master the application skills of the corresponding crops, and even if it is mastered, chemical fertilizers will bring a series of subsequent problems such as soil compaction and pest overgrowth.

Therefore, Daming is now unable to use chemical fertilizers on a large scale, and has no means to deal with the follow-up problems of chemical fertilizers.

But what Jiang Xinghuo knows is that the fertilization effect can far exceed that of manure and the fertilizer is less harmful, but it is not only a kind of nitrogen fertilizer made by soil coking

To put it bluntly, this is one of the easiest demonstration experiments to implement.

And the reason why the first step requires an old Taoist priest who can do alchemy.

It is because of this era that it is possible to master the process of refining green alum (sulfuric acid), and it is basically a person like an alchemy Taoist.

Only these ancient alchemy Taoists would study how to mix mercury, sulfuric acid, lead and mercury together every day to refine the brilliant and colorful "Golden Pill", and others would not study these.

The reason why alum is needed is because the ammonia produced by coking needs the corresponding liquid to be collected.

The "contact method" of the modern chemical industry, due to the limitation of the scientific and technological level of the Ming Dynasty, cannot be carried out at all, so the only options that can be chosen are the "lead chamber method" and the "dry distillation method".

The lead chamber method, the principle is simply to use saltpeter and sulfur to burn together, sulfur produces sulfur dioxide, saltpeter produces nitrogen oxides, and the two are mixed to produce sulfur trioxide, and further sulfuric acid is obtained.

As long as there is money, the lead room method can be realized in Daming.

But if the purpose is to demonstrate the nitrogen fertilizer manufacturing process, there is a simpler way.

- Dry distillation.

What is dry distillation, you ask?

The first step is to put a porcelain jar on the shelf (sulfuric acid will corrode the iron cylinder), the second step is to throw green alum into it, the third step is to ignite, and the fourth step is to mix it with water.

This is the dry distillation method, which is no different from the steps of chicken soup stewed in a porcelain pot.

So, in a nutshell.

Solid ammonium sulfate nitrogen fertilizer = soil coking + dry distillation + sun drying.

It's as simple as that.

With the current level of science and technology of the Ming Dynasty, this can be achieved easily, without any difficulty, and the cost is outrageously low.

If there is only a bit of "technical difficulty", it is the porcelain cylinder and the porcelain pipe for air conduction, which need to be strong throughout.

After figuring out these steps and the items needed, Jiang Xinghuo spoke.

"In the second step, you need coke, a coke oven, and a ceramic tube to guide the gas."

"Throw the coke into the coke oven and plug in the ceramic tube at the gas outlet, and the other end of the ceramic tube is aimed at the porcelain jar containing the alum liquid."

"The style of ceramic tubes."

Jiang Xinghuo raised his right hand, raised his thumb, tiger's mouth, and index finger and gestured at the U-shape, and said, "Just like this." ”

“……”

There was a moment of silence by the tree pit.

"What's wrong? These things are hard to get? You don't need to demonstrate today, you can entrust the old Taoist priest to go back and get it, and just take the finished product and try it in a small piece of farmland. ”

"It's not very hard to get."

Yuan Hui explained: "On the contrary, these are ready-made, I have the porcelain jars of burning alum in the warehouse of Yuan's house in Nanjing, and the porcelain tubes are directly removed from the things that make mercury. ”

"There are charcoal stoves, and there are also warehouses in the edict prison that don't need to be heated in winter, so they don't take them out."

"In other words, everything is available and ready in a moment."

Jiang Xinghuo looked at a few people and asked.

"Then why do you have this expression?"

Li Jinglong suddenly felt a pain in his head.

He looked at Yuan Hui and felt that the old Taoist priest's face was also full of despair.

"Mr. Jiang, are you serious? It doesn't seem like alchemy. Zhu Gaoxu asked after being silent for a long time.

Yuan Jue smiled bitterly: "The old man has practiced the pill all his life, and the charcoal smoke into the green alum liquid can refine the divine pill that can increase the fertility of the soil, and it is true that I have never refined it." ”

"You don't believe me?"

"It's not that I don't believe it." Li Jinglong said helplessly, "It's just this thing, it doesn't sound reliable!" ”

Jiang Xinghuo took a deep breath.

"I repeat, this is not alchemy, this is chemistry!"

"Chemistry is to refine elements from matter for reaction, so as to obtain the required elements."

Zhu Gaoxu said honestly: "It still sounds like alchemy. ”

Jiang Xinghuo, who was not in a good mood today, was almost close to breaking the defense for the first time during the lecture.

The main reason may be that he is talking about chemistry, and these people have been asking him if he is alchemy.

"Then if I tell you that the essence of this set of things is that nitrogen-containing heterocycles produce ammonia, absorb ammonia with concentrated sulfuric acid liquid, and then form liquid ammonium sulfate, and obtain solid ammonium sulfate after drying, solid ammonium sulfate is a kind of nitrogen fertilizer, which can increase soil fertility, do you sound like you?"

Li Jinglong concluded: "Such a divine statement, although I can't understand it at first glance, and I can't understand it after thinking about it carefully, but it sounds much more credible!" ”

Several people nodded in agreement as if chickens were pecking rice.
