I Build an Aircraft Carrier in the Ming Dynasty

Ichiro Xiongchuan tried to master Dahua's technology and catch up with Dahua by opening trade ports and sending foreign students to Dahua to learn this way.

This idea is good, and it does have some effects under normal circumstances.

However, the technological progress of Dahua today is not normal.

The progress of science and technology in history has relied on the research of geniuses for many years, slowly promoting the progress of science and technology.

And those latecomers to study, often can not take detours, directly in the right direction to study, naturally spend less time.

However, the development of Dahua Technology today mainly depends on Wu Changqing's system, which is countless times faster than normal.

It is impossible to keep up with Dahua by studying.

By the time they learn to build trains, Dahua should basically be able to build planes.

When they learn to build airplanes, Dahua should basically be able to enter the Internet age.

Moreover, for some core technologies, Wu Changqing also used many means to block and prevent leaks.

In Nanjing, Wu Changqing did not deal with government affairs, and came to a research institute that was heavily guarded.

Here are his designated ammonia projects.

To be precise, it is the urea synthesis and the amine phosphate project.

There are two main difficulties in the synthesis of urea, one is the preparation of ammonia gas, and the other is the synthesis of urea.

Urea synthesis requires ammonia and carbon dioxide to synthesize under high temperature and high pressure conditions.

Due to the study of steam engines, Dahua's high-temperature and high-pressure furnace technology is already very good, which can meet the requirements of urea synthesis.

The remaining difficulty is only the preparation of ammonia gas.

And this is naturally not difficult for Wu Changqing. He directly spent 100,000 technology points to light up the technology related to ammonia production.

Then Wu Changqing discovered that the production of ammonia is actually quite simple, just use nitrogen and hydrogen, and then add a very special catalyst.

It can be said that among these 100,000 technology points, 50,000 of the value is in the discovery of this catalyst.

People who don't know this catalyst, even if they know the theory that nitrogen and hydrogen can synthesize ammonia are useless, they will fail countless times in actual production.

And, every time you fail, you will be confused and unable to understand the reason for the failure.

Historically, the discovery of such catalysts was often the result of various coincidences rather than the result of research.

In science, some unreasonable things happen.

Now Dahua researchers no longer have to be tortured by this kind of thing, and Wu Changqing directly told them to join this catalyst.

Then, ammonia gas is easily produced.

Next is the synthesis of urea, Wu Changqing no longer needs to read more.

Ammonium phosphate fertilizers are neutralized with phosphoric acid and ammonia, and processed to obtain nitrogen-amine compound fertilizers.

This type of fertilizer is suitable for almost all soils and is the most widely used fertilizer.

Nitrogen amine and urea, two fertilizers can meet the fertilizer problems of almost all crops.

The difficulty in the preparation of ammonium phosphate also lies in the ammonia gas, which has now been solved together.

A few days later, someone brought the finished urea and nitrogen amines to Wu Changqing.

Smelling the familiar smell, Wu Changqing was very sure that this was the fertilizer, urea, and nitrogen amine that he used most often when he was farming in his previous life.

Urea and nitrogen amines are of great significance to agriculture. If fully promoted, at least the current grain output can be more than doubled.

Of course, if you want to fully promote it, I am afraid it will take another year or two, or even several years before it can be officially put into use.

Because the cost of synthesizing urea and nitrogen amines is still quite high at the current technological level, it is not particularly cost-effective to use them as fertilizers.

If it is not good, the money sold for the crops grown will not be enough to buy fertilizers.

But it doesn't matter, as long as you continue to optimize the process flow, improve efficiency, and find ways to reduce the cost of synthesis, this thing can be produced cheaply on a large scale sooner or later.

At that time, these two fertilizers can become a big killer in agriculture.

Doubling the growth means that with the current land, hundreds of millions more people can be fed.

In addition, a large amount of land has been reclaimed by mechanization, which can support countless more people.

As long as it reaches the level of later generations, the land of Everbright can support a population of more than one billion.

In the future, the Ganges River Basin in India will be taken up, and the Mississippi Plain in North America will be taken up again, and it will not be a problem to feed three billion people.

With enough food, enough labor can be liberated to develop industry.

This is an advantage that other countries cannot learn. For the backward agriculture of Fusang, at least 80% of the population needs to work in the fields to feed everyone.

Of the remaining two adults, once they are divided up by various industries, there are only a few left.

Without labor, even with technology, industry cannot develop.

A country with a large population like Fusang can't make up the labor force, and other countries are even more difficult.

In the original time and space, the industrial revolution in Britain was made by countless people at the bottom with blood and tears.

It relies on starvation to death of a large number of people at the bottom, as well as plundering the colonial food and starving the colonists to death to maintain the ration of factory workers and maintain the development of industry.

Although Britain took the lead in the Industrial Revolution, the country changed

is extremely powerful.

But when it comes to the living conditions of the people at the bottom, it is actually not as good as in the Qing Dynasty.

Unless Fusang, like the British Empire, developed industry by overdrafting the lives of the people at the bottom, it would not have developed.

This is why Wu Changqing attaches so much importance to agriculture and grain production.

He wants the rapid development of industry, but also to ensure that everyone has enough to eat, so that food production will not be reduced due to the reduction of the agricultural population.

"In the future, you don't have to do anything. It's better to find someone to feed you when you eat, and save all your time to study ways to reduce costs. This is a big issue that concerns the people of the country.

If you solve this problem within one year, I will reward you with a duke, and within three years, there will be only one marquis, and within five years, only earl. As for the problem that has not been resolved within five years, it is not allowed to be my student in the future. "

Wu Changqing told Lian Fujin that this person was also one of his first students.

Almost all of his first students are now talented, but their achievements vary.

A few have achieved significant results in important areas, others are working on it, and still others have limited talent and can only study less important areas.

However, compared with other people, this group of students are considered talents.

"Students keep the teacher's teachings in mind."

Lian Fujin said that of course he couldn't really find someone to feed himself. However, he also felt Wu Changqing's emphasis on these two fertilizers from Wu Changqing's words.

The title of a duke, no foreigner in Dahua has won this title yet.
