From Propulsion City To Multiverse

All the princes and Sui courts are planning their own plans.

The Human Revolutionary Alliance is consolidating its foundation and increasing its own strength as soon as possible to reduce casualties in the process of dynastic change.

Daliuqiu, Jianan Plain.

Over the past six months, a large number of immigrants from the north and Jiangdong have arrived, and Tang Feilin, who manages here, has built a large amount of infrastructure by using the method of work-for-relief.

There is a coal mine in the north of Jianan Prefecture. Although the reserves are only about 12 million tons, and it is still low-quality lignite, it is more than enough to be used as raw materials for cement plants and honeycomb coal plants.

At present, a cement plant with a monthly output of 1,500 tons has been built locally.

With the blessing of cement, Jianan Prefecture has completed 5 small reservoirs, 13 piers, 197 kilometers of rural roads (including 21 kilometers of cement roads), and 206 kilometers of river repairs.

At the same time, 6,750 houses were built, including 537 bamboo-reinforced concrete houses.

The reclaimed farmland is 860,000 mu, including 620,000 mu of Champa rice, 90,000 mu of sugarcane, 100,000 mu of flax, and 50,000 mu of banana.

Due to the different arrival time of different immigrants, the time of Champa rice planting is also different, resulting in different harvesting time of grain.

Tang Feilin is currently in charge of the reform work in Southeast State, so many things in Liuqiu State are done by Qiao Sancai.

This person was born as Tang Feilin's secretary. After more than a year of training, he is already able to act as an agent for part of the management work.

Qiao Sancai attaches great importance to the development of the Jianan Plain. .

Qiao Sancai, wearing a straw hat, stood by the endless rice fields like a villager and an old farmer: Comrade Zhongxin, you Xinfeng Township should take advantage of the slack time to build water conservancy, grain drying fields, and barns as soon as possible, so as not to get lost. Times are hectic.

Du Zhongxin, who is also very young, nodded: We have mobilized everyone as much as possible. These facilities are for everyone to use, and the people are very supportive.

Don't let the people do free work, don't do any voluntary labor, it's not good! Qiao Sancai reminded.

Du Zhongxin also knows the alliance's regulations: I know that the projects are all carried out in special accounts, and people's wages will not be deducted.

Qiao Sancai was still very serious: Don't be careless, the black guards and the inspector's office can keep an eye on these, don't be corrupted, as long as we realize Datong society, we will not be short of that little money then.

I must pay attention. Du Zhongxin was also a little scared when he heard the guards in black and the inspection office.

However, he thought about his work carefully and found that there was no problem, and he was not afraid of being investigated.

At the edge of a golden rice field, more than 20 households who immigrated three months ago are busy harvesting.

Looking at the full-grained rice, Qiao Sancai asked, How much is the current Champa rice yield per mu in your township?

Du Zhongxin replied excitedly: Only rice fields with cooked fertilizers and no chemical fertilizers have an average yield of 120-130 kilograms per mu; paddy fields with chemical fertilizers have an average yield of 180-190 kilograms per mu, Governor! If...

No, the fertilizer quota has been allocated.

Du Zhongxin scratched his head helplessly.

Obviously, the application of chemical fertilizers has given many farmers a taste of the sweetness.

It should be known that when no chemical fertilizers or fermented organic fertilizers are used, the yield of Champa rice is about 100 kilograms per mu when the weather is good.

After using fermented organic fertilizer, the yield can be increased to 120-130 kg per mu.

With the use of chemical fertilizers, this can be increased to 180-190 kg per mu.

This is not the limit. In some experimental fields of the Department of Agriculture, there are Champa rice with a yield of 240 kilograms per mu. That is the limit yield per mu that can be obtained after reasonable addition of chemical fertilizers.

Although there are no high-yield varieties such as hybrid rice, chemical fertilizers can also increase crop yields.

Moreover, compared with cross-breeding, increasing the production of chemical fertilizers is the kingly way in the classical era. After all, cross-breeding needs more than ten years to start, and even decades may not be fruitful.

However, the effect of chemical fertilizers on increasing production was immediate.

At present, there are three main channels to obtain the chemical fertilizers of the Human Leather Federation: synthetic, semi-artificial, and natural fertilizers.

There are four types of synthetic fertilizers: potassium nitrate, superphosphate, potassium sulfate, and ferrous nitrate.

Semi-artificial fertilizers are potassium nitrate and fish bone meal phosphorus and potassium fertilizers produced by the nitrate method.

The natural chemical fertilizer is struvite phosphate, which is a natural compound fertilizer of nitrogen, phosphorus and potassium, and is currently the largest chemical fertilizer produced by artificial leather.

There are not a few struvite mines on the surrounding islands of Liuqiu Island, and the reserves of struvite in the entire South China Sea Islands are about 1.5 million to 2 million tons.

As for why there is no data in this regard in later generations.

That's because the guano resources on these islands have been plundered by Western powers and Japanese people.

After 1850, these external forces, openly or covertly, illegally harvested and robbed the struvite resources on the South China Sea Islands. By the time of the 21st century, there were already very few resources left on the islands.

The struvite resources on these islands are still undiscovered. When Tang Feilin was in charge of Liuqiu Prefecture, he established the Penghu Phosphate Mining Company.

At present, a total of 13 islands with struvite resources have been discovered on the surrounding small islands, and 300-500 tons of struvite can be mined every month.

The struvite resources of the South China Sea Islands are enough for the Human Revolutionary League to use for a period of time in the early stage.

If the resources here are exhausted, there is also the super large mine on Nauru Island. The total struvite phosphate reserves on it are about 110 million tons, which is enough to be mined for decades.

Therefore, the Human Leather Federation now uses synthetic fertilizers on the one hand and struvite mining on the other.

Chemical fertilizers can increase the yield of crops by about 30-50%, especially in the absence of good varieties, and are currently the core technology for increasing yield per mu.

1 ton of struvite can increase 3 to 4 tons of grain under the condition of reasonable use.

The Penghu Phosphate Mining Company mines 4,000 tons of struvite a year, which can increase grain production by 12,000 to 16,000 tons, and obtain food rations for 30,000 to 40,000 people a year.

Fertilizer is the core technology to fill the human stomach, and it is the first element.

Many people think that good breed is the core, which is definitely a big mistake.

Some people have studied the so-called chemical fertilizer-free planting. Even if a large amount of organic fertilizer is used, the unit yield of crops is still 30-40% lower than that of crops using chemical fertilizers.

Without fertilizers, the earth's land can only feed a maximum of 2 billion people.

Therefore, chemical fertilizer is the first element of agriculture, followed by improved seeds.

If you think that with the high-yield seeds of later generations, you can get thousands of catties of rice and wheat per mu, and thousands of catties of potatoes and sweet potatoes in ancient times, that is simply wishful thinking.

In nature, not only energy is conserved, but elements are also nearly conserved.

Without human intervention, there is no way for the nutrients of a piece of land to skyrocket naturally. This is also the fundamental reason why many farmlands in ancient times would become more and more barren, and finally had to be fallow.

Without chemical fertilizers, high-yield crops will quickly suck up the nutrients in the land, and the seeds with a yield of 10,000 jin per mu will be useless.

This is just like the race of later generations, East Asians can grow to 1.8 meters or 1.9 meters when they have sufficient nutrients.

But being able to grow to 1.8 meters does not mean that one can grow to 1.8 meters. No matter how good the genes are, they cannot withstand the weakening of malnutrition.

The same is true for crops. Champa rice has the potential to yield 240 kilograms per mu, but without enough nutrients, it will not be able to grow 240 kilograms per mu anyway.

...

After inspecting several townships, Qiao San discovered that struvite compound fertilizer had a significant effect on increasing production, so he hurried to Penghu County by boat.

The total area of ​​the Penghu Islands is small, only about 94 square kilometers. The current total resident population is 3,375 people, all of whom are employees of Penghu Seafood Company and Penghu Phosphate Company and their families.

Gu Hong

Arriving at the struvite finishing factory of Penghu Phosphate Company, manager An Li introduced the company's situation to Qiao Sancai:

Governor, our company currently has 627 employees, five 150-ton transport ships, and one processing plant.

What about the struvite mines?

An Li explained: Currently, 13 islands with struvite have been explored, with a total reserve of 87,000 to 95,000 tons, and a mineral grade between 30% and 65%.

Qiao Sancai shook his head: Not enough, the output is not enough. At least an annual output of about 50,000 tons can meet the current needs of the three states.

An Li smiled wryly at this: Governor, we also want to expand production, but the surrounding islands of Liuqiu have already been explored, and the total reserves are only so much, and the distance to the struvite on the sands of the South China Sea is a big problem.

Let's do this! You don't need to worry about the reserves and continue to expand the mining volume. We won't have to worry about transportation soon.

Qiao Sancai, who knew some inside information, made the most reasonable arrangement.

Since the superior has a solution, Anli naturally has no objection: Then I will report to the Ministry of Mining and apply for expansion of production.

Well, you send the report directly to the Ministry of Mines and say that I approved it.

clear!

Food production is too important for the Human Revolutionary Federation.

In other words, food is as important as the army to human society before controllable nuclear fusion is mastered.

After all, people depend on food.

Leaves and hay can be used without clothes, stone and wood can be used without metal, and immunity can be used without medicine.

But if there is no food, there is no way.

After humans entered the feudal era, simple hunting and gathering could no longer meet the overall food needs of human society.

Even nomads actually need food.

Don't be surprised, they not only need food, but also a lot of it.

Don't be misled by the nomads in modern society. In fact, the nomads in the classical era could not drink and eat meat every day. Their cattle and sheep were equivalent to farmers' farmland, and ordinary herdsmen ate dairy products, grains and grass seeds.

The nomadic people in Mobei, every year, sow grass seeds and grain seeds in the valley plain before going south for the winter, and then come back next year to harvest.

Even in the tribe, there are special serfs who specialize in growing grain.

...

the other side.

Freshwater Steel Works.

The iron and steel plant, which has been continuously upgraded, now has 12 small blast furnaces, and its monthly pig iron production has reached a scale of 3,600 to 4,800 tons.

In terms of smelting technology, gas heating technology and pure oxygen decarburization technology have been successively developed.

In particular, the emergence of pure oxygen has made the quality of steel more controllable. In addition, Liuqiu Prefecture itself has manganese ore, and now the steel plant can already smelt manganese steel.

As for how to obtain pure oxygen.

very simple.

Not far from the steel plant, a thermal power plant has been built to generate electricity using waste heat from the steel plant and coal.

Then use the electric energy of the thermal power plant to electrolyze water to obtain oxygen and hydrogen, and then use mercury to absorb oxygen and turn it into mercury oxide to purify hydrogen.

The hydrogen is sent to smelt steel.

After the mercuric oxide is heated, pure oxygen and mercury can be obtained. The mercury is recycled, and after the oxygen is purified, it is stored in a steel cylinder made of high manganese steel.

Now the iron and steel plant can produce 3,600-4,800 tons of pig iron every month, and then use these pig irons to further smelt stable high-quality steel. The monthly output is about 1,200-1,500 tons.

And because the electric energy of thermal power plant is relatively abundant, utilize these electric energy again, supply a batch of electric machine tools.

Long Sha is here right now, with hundreds of assistants, using forging presses, stamping machines, electric machines, and foundry castings to create the first batch of mature steam engines.

The power of these steam engines is already quite high, a single unit can reach about 2,000 horsepower, and the thermal efficiency is close to the level of 1930.

With the completion of the final inspection, Long Sha looked at the steel machine that spewed black smoke, it was the man-made power of industry, roaring towards this era.

There are a total of 12 high-pressure steam engines developed by her, which are to be placed on ships.

Freshwater Shipyard has built six Roaring-class hybrid ships.

The roaring class has a full load displacement of 1,800 tons and a payload of 1,100 tons. It has 5 hard sails, 32 watertight cabins, steel structure split wooden keels, and a large number of steel structural components.

The reason why a large number of steel structural components are used is to strengthen the overall strength to adapt to the steam engine.

Daye 13 January 2014.

The first ship of the Roaring class has completed the installation of the steam engine. In terms of design, Longsha directly skipped the paddle wheel and entered the stage of propeller propulsion.

As for the early water leakage of the propeller, she used high-precision components and oil seal technology.

After the boiler was heated up, a sharp siren sounded in Danshui Port. The farmers who had just immigrated from the north saw this scene, as if they had seen a miracle.

Long Sha asked the boiler worker to turn up the firepower to the maximum.

Half an hour later, the power of the Zhu Rong 1 steam engine reached its maximum, providing a strong power of 2130 horsepower.

While the Roaring class is in the state of steam propulsion, it will lower the hard sails to reduce the resistance of the ship's navigation.

At this time, the speed of the Roaring class reached a high speed of 19 knots. For wooden ships, this speed is already the limit. If the speed is faster, the structure of the ship will not be able to bear it.

And long-term use of steam engine with maximum power is not conducive to the thermal efficiency and service life of steam engine.

The highest power will be used now just for testing.

According to Longsha's estimation, the cruising speed of the Roaring class is maintained at about 10 knots, which should be the most cost-effective economical speed.

The roaring class has a thermal coal reserve of 150 tons, and can sail about 4,200 kilometers at an economical speed of 10 knots.

If the high-speed mode is used, that is, at a speed of 16 knots, the cruising range is only 2100 kilometers, and the mechanical failure rate will rise rapidly.

However, the steam engine has another advantage, that is, under special circumstances, charcoal and wood can be used as fuel to maintain a speed of 10 knots.

After all, coal is not available everywhere, especially for steamships exploring unknown seas, charcoal and wood can be burned to ensure endurance.

And the sails must be preserved, otherwise, if the steam engine fails and you happen to be on the vast sea, without sails, you will really be doomed.

Long Sha commanded the Roar, crossed the Liuqiu Strait from Danshui Port, and sailed directly against the northwest wind to Zhoushan Port.

Maintain a speed of 10 knots throughout.

It arrived at Zhoushan Port in less than two days. Since the Roaring was loaded with 200 tons of coal, it was enough to go back and forth several times.

After an overhaul at Zhoushan Shipyard, Long Sha found no major problems, and hurriedly returned to Danshui on the Roar.
