Chapter 2103: Earthworm breeding succeeded

"The rise of the emperor (!

In fact, Marin was like making industrial adjustments and upgrading the economic structure early on. But the problem is that there is a serious shortage of labor in this era. It is irrational to develop industry when there is a shortage of farmers. Because there is no surplus population.

The areas in charge of industrial development are all areas with surplus agricultural population. For example, the Flanders region has been densely populated since ancient times and has a surplus labor force to engage in the woolen industry. Italy is the same, with many mountains and small plains, dense population, and a surplus of labor to work as workers. Later, Britain also benefited from the enclosure movement and there were a large number of landless farmers, so it developed the textile industry and also initiated colonial development.

Therefore, time is also fate, history is really full of contingency, and there are no laws to talk about. Because of the excellent agricultural conditions in France, the French lacked the motivation to emigrate, which led to the loss of the colonial competition to Britain. The British Enclosure Movement's wicked and smoking behavior, on the contrary, stimulated the development of industry and the cause of colonization. Similarly, the Central Plains dynasty in China also lost the opportunity for colonial expansion because it lacked everything in its homeland and the motivation to explore overseas, coupled with the conservativeness of Confucianism. 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 nations around, Japan and South Korea are still twenty-five...

When there is a shortage of agricultural population, working in industry will definitely harm agriculture. And agriculture is fundamental. Agriculture is not good. People are starving to death. Industry that engages in football? Therefore, when Marin thought about development, he had to wait for hundreds of thousands of peasants to become serfs before he could liberate the farmers from the North Sea country and let them become craftsmen and workers.

Moreover, Da Vinci's School of Mechanical Engineering is constantly perfecting the steam engine. After a few years, the steam engine and the single-cylinder diesel engine will become stable and will not break easily. This will improve agricultural efficiency and free up more labor.

Now, the steam engine is okay, it's already stupid and clumsy. Single-cylinder diesel engines often fail due to many details. Each single-cylinder diesel engine must be equipped with several college students in the mechanical department to maintain it at any time to keep it running. Da Vinci's team pursued the long-term operation of the diesel engine without any problems. At that time, it can be extended to agriculture. Of course, the spindle-top oil fields must also be developed in time. Otherwise, if the diesel engine is stable, but diesel is not available, that would be funny.

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

If copper pipes are used, at the current price of copper, the cost of a curved water pipe is very expensive. Moreover, copper pipes tend to soften after being heated. The steam in a high-pressure boiler can easily reach 500 degrees, but at this temperature, the copper begins to soften. However, the pressure of the high-pressure boiler is high, and the copper tube is softened again, which can easily cause trouble.

Fortunately, the North Sea is home to stainless steel. Now, Da Vinci's steam engine team is trying to use stainless steel to roll, weld, and bend into a curved sealing water pipe to achieve its goal.

Once the high-pressure boiler is successfully studied, not only can the thermal efficiency and power of the steam engine be improved, but it can also be applied to the steam turbine. There are as many coal resources as the Ruhr area and England. If a breakthrough is made in steam engine technology, the value is greater than that of a single-cylinder diesel engine.

If it can be applied to a tractor, Marin is probably happier. However, the miniaturization of the steam engine is indeed too difficult for the lack of basic mechanics.

Moreover, only after having a high-pressure boiler can the steam locomotive be miniaturized. Otherwise, the steam engine is too small, and the horsepower provided is not enough to output the power to plow the soil. And if the steam locomotive is too large and heavy, it is not suitable for being a tractor. Because a machine that is too cumbersome will harden the ground and easily sink into the loose soil.

Only the mechanization of agriculture can liberate most of the peasants from the land and enter the cities to become workers or merchants. However, it seems that Da Vinci's team failed to achieve the robustness and durability of a single-cylinder diesel engine, so the process seems a bit long. Before that, Marin could only count on gaining more population.

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

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

Only nitrogen fertilizer, because of the smell of manure, Marin has always been worried about the leakage of technology. Although the feces were air-dried for several months to remove the odor. However, it still leaves a very light smell. It is easy to be seen through when you meet experienced elderly people.

Therefore, Marin would think of the method of later generations to study the use of feces to feed earthworms, and then use the odorless earthworm feces as the nitrogen fertilizer.

However, finding suitable species of earthworms and raising earthworms with human feces are still quite difficult. Take the issue of earthworm species. Ma Lin remembers that later generations were made by Japanese people using earthworms native to the country of Japan and crossed with a red earthworm from eastern North America.

At the moment, it is difficult to go to Japan to find that species of earthworm due to difficult transportation. Moreover, Marin doesn't know what breed it is. It's the red worm in eastern North America, which is easier to find.

In desperation, Marin had to let his professional staff use bloodworms from the New York area to crossbreed with various local species of bloodworms. Then, feed with cow dung to see which species of earthworms produce more worm dung after eating cow dung...

This method is rather rigid, but there is no better way. I can only wait slowly and watch the recorded results.

But the result is that, let alone raising earthworms with human dung, it is troublesome to even raise earthworms with cow dung. Because, the researchers discovered-if the cow dung is not fermented first, if the earthworms directly put on the cow dung, the cow dung will release toxic substances during the fermentation, which will poison the earthworms.

Moreover, after a long period of observation. Not only does cow dung need to be fermented, but the fermented cow dung must also be added with some water in order to raise earthworms. Because earthworms like humid environments and don’t like to eat dry cow dung...

As for Ren Xiang, it is even more troublesome. Even after fermentation, earthworms will still be poisoned. Ma Lin believed that Renxiang had high salt content, so he asked the researchers to ferment and wash Renxiang to remove the high salt content.

But after washing off the salt, Renxiang lost a lot of nutrients, and the effect of raising earthworms is far inferior to cow dung. So, Marin thought for a while, and discussed with the researchers, mixing in chopped and rotting grass and leaves on the basis of Renxiang washed in fermented water. And earthworms just like the decaying impurities generated by rotting grass and leaves. As a result, Renxiang finally made a breakthrough in raising earthworms.

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

Therefore, in the spirit of not wasting, Marin mixed and stirred the solution after washing in Renxiang water with the loess, and waited for it to dry and ferment for a few days before using it to boil the soil. So, no waste...

As for the earthworm farming side, when the spring of 1517 is approaching, it finally barely succeeded!

Although the earthworm species may not be as good as the later scientific species, the effect is not so good. However, it is enough. Therefore, Marin ordered every **** treatment site across the country to start fermenting and washing the feces, mixing the rot from the weeds and leaves, and then raising the earthworms to obtain earthworm feces.

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

The worm dung looks like dirt. Even if it is stolen by a foreign spy, it may be difficult to identify. I would never think that it came from Renxiang...

In addition, the bred earthworms are also high-grade feed, which is absolutely high in protein. After the hens ate, the egg production rate increased significantly...

However, for the sake of confidentiality, feces disposal and earthworm breeding sites are separated. Moreover, deliberately stayed far away. Even this method of boiling soil in the 20th century is considered confidential. Because the Europeans these years only know that the nitrate is scraped on the corners of the feces, and they do not know that they are prepared by actively stirring the loess with urine in the feces. Therefore, the yield is very low.

Moreover, there is a transfer station between the manure treatment plant and the earthworm breeding plant. The task of this transfer station is to stir the rotten weeds and leaves into the fermented and washed Renxiang. At this time, it is already difficult to see that it is a human being. After all, the rotten weeds and leaves will look black and gray when mixed.

And then transported to the earthworm breeding farm, UU Reading www.uukanshu. com is used to feed earthworms and produce worm feces... Several processes are not experienced in the whole process, and I don’t know the twists and turns. Because the processes are strictly separated, even the places are separated. Therefore, even if foreign spies catch workers, they can't ask for 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 important places such as earthworm breeding farms. Moreover, spies will be sent secretly to monitor and secretly arrest all those who dare to inquire about the news. In this way, it is possible to ensure that confidentiality is not leaked as much as possible.

Even after the earthworm feces are mixed with phosphate fertilizer and potash, they will be quietly transported out to sea in the middle of the night, and then returned to the dock during the day, pretending to be "volcanic ash" shipped back from Iceland. Of course, this is only part of it. Otherwise, all fertilizers pretend to be so, which is a waste of manpower and material resources. As long as part of the fertilizer is taken off the field, it can be regarded as an explanation of the "source" of the fertilizer to the outside world...
