The Rise of the European Emperor

"The Rise of the European Emperor ()"!

In fact, Marin seemed to have carried out industrial adjustments and upgraded the economic structure very early. But the problem is that there is a serious shortage of labor in this era. It is irrational to develop industry in the absence of farmers. Because, there is no redundant population.

The areas in charge of industrial development are all areas with a surplus agricultural population. For example, Flanders has been densely populated since ancient times, and there is a surplus of labor force engaged in the wool spinning industry. Italy, too, has many mountains and few plains, is densely populated, and has a surplus labor force to work as workers. Later Britain also benefited from the enclosure movement, and had a large number of landless farmers, so it developed the textile industry and colonized development.

Therefore, time is fate, history is really full of chance, and there is no law to speak of. Because of the good agricultural conditions in France, the French lacked the motivation to immigrate abroad, which led to losing to Britain in the colonial competition. However, the immoral behavior of the British enclosure movement stimulated the development of industry and the cause of colonization. In the same way, the Central Plains Dynasty of Huaxia lost the opportunity for colonial expansion because it lacked nothing at home and lacked the motivation to explore overseas, coupled with Confucianism's conservativeness. In the end, after Huaxia developed, it was suddenly discovered——it seemed that the whole world was occupied by white people. And the few yellow countries around me, Japan and South Korea are still twenty-five...

When the agricultural population is insufficient, engaging in industry will definitely damage agriculture. And agriculture is fundamental, if agriculture is not good enough, people will starve to death, what about the ball industry? Therefore, no matter how much Marin thinks about development, he has to wait until hundreds of thousands of Maozi become serfs before he can liberate the farmers of the original Beihai country and let them become craftsmen and workers.

Moreover, Leonardo Da Vinci's School of Mechanics is also constantly improving the steam engine. After a few years, when the steam engine and single-cylinder diesel engine are stable and not easy to break down, the efficiency of agriculture can be improved and more labor force can be freed up.

Now, the steam engine is okay, but it is stupid and clumsy. Single-cylinder diesel engines often go wrong due to many details. Every single-cylinder diesel engine must be maintained by several college students from the mechanical department at any time to keep it running. Da Vinci's team is pursuing the long-term operation of the diesel engine without failure. At that time, it can be extended to agriculture. Of course, the oil fields at Spindle Top must be developed in time. Otherwise, the diesel engine is stable, but the supply of diesel is not available, it would be ridiculous.

As for the steam engine, the goal of the School of Mechanical Engineering is to miniaturize and increase power and speed. For this reason, Marin put forward an opinion and asked them to develop a high-pressure boiler. The main thing is to use bent water pipes and economizers. One of the difficulties is to bend the water pipe.

If copper pipes are used, at the current copper price, the crooked water pipes will cost a lot. Moreover, the copper tube is easy to soften after being heated. The water vapor in a high pressure boiler can easily reach 500 degrees, but at this temperature, the copper starts to soften. However, the pressure of the high-pressure boiler is high, and the copper pipe softens again, which is easy to cause accidents.

Fortunately, Beihai has state-owned stainless steel. Now, Da Vinci's steam engine team is trying to use stainless steel to roll, weld, and bend it into a crooked sealed water pipe.

to achieve the purpose.

Once the high-pressure boiler is successfully researched, not only can the thermal efficiency and power of the steam engine be improved, but it can also be applied to the steam turbine. Coal resources in the Ruhr area and England are as much as they need. If a breakthrough in steam engine technology is achieved, the value will be greater than that of a single-cylinder diesel engine.

Marin would probably be happier if it could be applied to a tractor. It's just that the miniaturization of the steam engine is really too difficult for the lack of foundation in the mechanical school.

Moreover, only after having a high-pressure boiler, can the steam locomotive be miniaturized. Otherwise, a steam engine that is too small in size will not provide enough horsepower to output enough power to plow the soil. And if the steam locomotive is too large and heavy, it is not suitable for tractors. Because an overly bulky machine will compact the ground and easily sink into the loose soil.

Only with the mechanization of agriculture can most peasants be liberated from the land and enter the cities to become workers or businessmen. But it seems that Da Vinci's team failed to realize the robustness of the single-cylinder diesel engine, so the process seems to be a bit long. Before that, Marin could only count on getting more population.

Before the realization of agricultural mechanization, Marin could only rely on fertilizer technology to maintain its agricultural advantages. It is to use limited arable land and labor force to produce more food.

The core of fertilizer technology is the complete set of nitrogen, phosphorus and potassium fertilizers. Among them, phosphate and potash fertilizers are not worried about other countries finding out. Because, they don't understand. Moreover, there are no apatite mines in Europe. As for potassium salt, how can other countries know the flame reaction to identify it?

Only nitrogen fertilizer, because of the smell of manure, Marin has been very worried about technology leakage. Although the feces were air-dried for several months to disperse the odor. However, there will still be a faint odor. It is easy to be seen through when you meet an experienced old man.

Therefore, Marin remembered the methods of later generations, researched feeding earthworms with manure, and then used earthworm manure that smelled like soil as nitrogen fertilizer.

However, it is quite difficult to find suitable earthworm species and raise earthworms with human feces. For example, on the issue of earthworm species, Marin remembers that the later generations were hybrids obtained by the Japanese using a local species of earthworm from the Japanese country and a red earthworm from eastern North America.

Right now, it is very difficult to go to Japan to find that species of earthworms because of the difficult transportation. Moreover, Marin didn't know what breed it was. On the other hand, red earthworms in eastern North America are easier to find.

In desperation, Marin had to let his professionals use the red earthworms in the New York area to hybridize with various local species of red earthworms. Then, feed them with cow dung to see which species of earthworms produce more vermicompost after eating cow dung...

This method is relatively rigid, but there is no better way. We can only wait slowly and see the recorded results.

But the result is that, not to mention raising earthworms with human feces, even raising earthworms with cow dung is quite troublesome. Because, the researchers found that if the cow dung is not fermented first, if the earthworms directly put on the cow dung, toxic substances will be released during the fermentation of the cow dung, which will kill the earthworms.

Moreover, after a long period of observation. Not only does cow dung need to be fermented, but also some water must be added to the fermented cow dung to feed earthworms. Because earthworms like a humid environment and don't like to eat dry cow dung...

As for Renxiang, it is even more troublesome. Even after fermentation, it will still poison the earthworms. Marin thought that Renxiang was high in salt, so he asked the researchers to ferment Renxiang and then wash it with water to remove the high salt content.

But after washing away the salt, the nutrients in human worms have lost a lot, and the effect of raising earthworms is far inferior to that of cow dung. So, after thinking about it for a while, Marin discussed with the researchers that on the basis of the Renxiang washed in fermented water, mix chopped rotten grass and leaves. And earthworms just so happen to love the decay that rotting grass and leaves produce. Therefore, Renxiang finally made a breakthrough in raising earthworms.

However, the problem is that after washing with water, the elements in the human body are also dissolved by the water along with the salt. The experience of later generations told Marin that nitrate is actually mainly formed by mixing the liquid in manure and loess.

Therefore, in the spirit of not wasting, Marin mixed the solution washed by Renxiang with the loess, and waited for it to dry and ferment for a few days, and then used it to boil the soil. So, don't waste...

As for the earthworm breeding, when the spring of 1517 was approaching, it was finally considered a success!

Although the earthworm variety may not be as good as the scientific variety of later generations, the effect is not so good. However, it is enough. Therefore, Marin ordered all manure treatment sites across the country to start fermenting and washing the manure, and then mix the weeds and leaves with rotting impurities, and then raise earthworms to obtain vermicompost.

At the same time, the solution washed with water is also used to boil soil nitrate, and a lot of soil nitrate can be obtained, which can be said to kill two birds with one stone. Of course, vermicompost is not the final product, and it needs to be mixed with apatite (or sulfuric acid-treated phosphate) and potassium salt. Only then can it be used as a compound fertilizer to exert the best effect.

Vermicompost looks like dirt, even if it is stolen by foreign spies, it may be difficult to identify, and it will never be thought that it comes from humans...

In addition, the raised earthworms are also high-grade feed, absolutely high in protein. After the hen ate it, the egg production rate increased significantly...

However, for the sake of confidentiality, the sites for manure disposal and earthworm rearing are separated. Moreover, it is deliberately far away. In fact, even this 20th-century method of boiling soil and nitrate is considered a secret. Because Europeans these days only know how to scrape nitrate from the corners of cesspools, and they don’t know how to actively stir loess with urine in feces to produce it. Therefore, the yield is low.

Moreover, there is a transfer station between the excrement treatment field and the earthworm farm. The task of this transfer station is to stir the rotting weeds and leaves into the fermented and washed Renxiang. At this time, it was already difficult to see that it was Renxiang. After all, rotting weeds and leaves look gray and black when stirred together.

Then it is transported to an earthworm farm, where it is used to feed earthworms and produce vermicompost... After several processes, I did not personally experience the whole process, and I do not know the twists and turns. Because the process is strictly separated, even the places are separated. Therefore, even if foreign spies capture workers, they will not be able to find any useful information. After all, they only know the situation of their own process, not the whole process...

And Marin will not give others the opportunity to inquire, he will not only send troops to protect key places such as earthworm farms. Moreover, spies will be sent to spy on and arrest anyone who dares to inquire about the news. In this way, it is possible to ensure that the confidentiality is not leaked as much as possible.

Even after the vermicompost is mixed with phosphate fertilizer and potassium salt, it will be quietly shipped out to sea in the middle of the night, and then returned to the pier during the day, pretending to be "volcanic ash" shipped back from Iceland. Of course, this is only part of the story. Otherwise, it would be a waste of manpower and material resources to pretend that all fertilizers are in this way. As long as some of the fertilizers go through the motions, it can be regarded as an account of the "source" of the fertilizers to the outside world...
