Rubber is one of the most important industrial raw materials of the Second Industrial Revolution and an economic plant unique to South America.

Therefore, in order to ensure that Rio Gran do Sul can catch up with the development opportunities of the second industrial revolution, Li Mingyuan has made important plans and arrangements for the development of the rubber industry.

First of all, expand the planting area of rubber plantations to ensure the adequate supply of rubber raw materials.

After more than nine months of searching and transplanting, the number of rubber plantations in Rio Gran do Sul reached more than 60 and the number of wild rubber plants reached 200,000 by September 1869, since the discovery of wild rubber in the territory at the end of 1868.

Among the more than 200,000 rubber trees, about 70,000 adult rubber trees can obtain rubber raw materials, accounting for one-third of the total number of rubber trees.

Wild rubber trees can generally secrete rubber liquid in four to five years, and rubber liquid can be harvested in eight to ten years. The economic life span is between 25 and 30 years, and the growth life is about 60 years.

The economic life span of the bud tree is much shorter than that of the wild rubber tree, about 20 years, but the economic life span of the bud tree is greatly shortened, because the seedling is cultivated by the bud grafting technology, the growth and maturity period and cultivation difficulty of the bud tree are greatly reduced, which is conducive to large-scale planting.

Most of the rubber trees suitable for transplanting and management in Rio Gran do Sul have been found, and a small number of rubber trees have not been found because they are deep in the jungle and mountains, but because of the inaccessibility of the jungle and the mountains, those rubber trees do not have the economic value of transplanting.

The number of wild rubber trees will not increase significantly in a short period of time, and in order to increase the total number of rubber trees, it is more effective to cultivate new seedlings by budding.

There are 13 wild rubber tree plantations in Hexi County, in the central part of Rio Gran do Sul, where 50,000 seedlings cultivated by budding technology are planted in specially developed plantations, and according to more than half a year's experiments and statistics, 30,000 of the 50,000 budding seedlings have survived, with a survival rate of about 60 percent.

Budding seedlings generally grow in the culture area for two years, and then can be transplanted to the plantation to grow, in the process of transplanting to the plantation, there will be a part of the seedlings die due to soil discomfort and other factors, so the total survival rate of sprouted seedlings is about 40%.

Therefore, after the report on the growth of bud-grafted rubber seedlings came up, Li Mingyuan set a target for the officials in charge of managing rubber planting, to increase the total number of rubber plantations to 300 within three years, and to reach the scale of more than 1 million rubber trees.

There are about two to three million rubber trees cultivated in Brazil, and with the size and volume of Rio Gran do Sul, one million rubber trees is enough to supply the raw materials needed for the development of the rubber industry.

The total amount of rubber trees is the first problem that restricts the development of the rubber industry, and the development and improvement of the rubber industry system is the second problem.

In the seventies of the nineteenth century, the second industrial revolution had just begun, and the automobile industry and the internal combustion engine that promoted the development of the rubber industry in the future had not yet been invented. According to the original trajectory of history, more than ten or twenty years later, the rubber industry will usher in the opportunity to take off, and with more than 100 years of knowledge in later generations, Li Mingyuan can find a new development direction for the rubber industry in advance on the basis of existing science and technology.

Rubber-soled cloth shoes is the first successful product of the rubber industry to become practical, more than half a year ago, when Li Mingyuan inspected the work of Chinese workers, burst out of the idea of inventing rubber-soled cloth shoes, and after the demonstration and negotiation of technical workers on both sides of the garment factory and the rubber factory, the feasibility of manufacturing rubber-soled cloth shoes was verified, four months ago, the military garment factory of the National Defense Forces produced the first batch of military rubber-soled cloth shoes, and then after a month of trying and improving, the first rubber-soled cloth shoes were officially produced and began to be used as a new standard equipment for the troops.

Because it was the first time to produce rubber-soled cloth shoes, the production capacity of the military garment factory was just 300 pairs of rubber-soled cloth shoes per day, and then through three months of practical production to explore and summarize experience, the production capacity of the garment factory gradually increased, and finally stabilized at a daily output of 500 pairs of rubber-soled cloth shoes, with a monthly output of 15,000 pairs, and a total of 39,000 pairs of rubber-soled cloth shoes were produced in more than three months. Caught up with the production purpose of refitting the field units of the Wehrmacht by the beginning of September.

After completing the task of developing and producing rubber-soled cloth shoes, the Prussian and Chinese employees in the rubber factory immediately devoted themselves to the task of developing pneumatic rubber tires and producing hard rubber water pipes.

Hard rubber water pipes have already been invented in Europe, and since the technology related to rubber production was imported directly from Prussia when purchasing machinery and equipment, what the employees in the rubber factory had to do was to produce suitable products according to the standards provided by Li Mingyuan, which was not too difficult.

Although pneumatic rubber tires are a new business, according to the production ideas provided by Li Mingyuan, it is not difficult to invent pneumatic tires.

Under Li Mingyuan's close attention, hard rubber water pipes and pneumatic rubber tires were produced two days after the rubber-soled cloth shoes were installed in the troops.

After inspecting the performance of the new product, accompanied by several Prussian technicians from the rubber factory, Li Mingyuan praised the employees who participated in the production, then gave them a part of the reward in the name of the government, and finally ordered his entourage to take samples of pneumatic tires and hard rubber pipes with them to a newly established machine factory.

The Xinjing Machinery Factory, named after Xinjing, is a new factory that was established less than two months ago, and the technicians in the factory are all Chinese workers drawn from various machine factories, and there is not a single Prussian.

Walking into the interior of the heavily guarded machinery manufacturing factory, more than a dozen Chinese technicians in the main workshop of the factory stood in a neat row to greet Li Mingyuan and his party.

"Old Wangtou, have the products I ordered you to produce have been done?"

Li Mingyuan strode into the door of the workshop and asked directly.

"Yangjing and Yangche each produced forty samples, and only the rubber product accessories brought by His Highness can be assembled."

A diminutive Chinese man in his forties laughed.

"I've brought everything, according to the structural diagram I handed over, let's assemble two complete samples first."

Li Mingyuan glanced at the mechanical products arranged in two rows in the workshop and waved his hand.

"Your Highness." The old factory director saluted Li Mingyuan,

Five or six Chinese mechanics were beckoned to take the rubber parts brought by the entourage, and then began to tinker with the two mechanical products.

After about 20 minutes, the old factory manager with black hands completed the assembly, and two products that were very common in later generations appeared in the eyes of everyone in the workshop.

The two production technologies produced in the workshop are not too high, but their inventions or improvements have a great effect on the lives of ordinary people.

The first of the two products has been invented in European society for more than half a century, and the Chinese workers who have seen it in the workshop habitually call it a foreign car, while Li Mingyuan prefers to call it a bicycle.

For the products produced by Westerners, Chinese workers are accustomed to adding a foreign character in front of the name, such as the matches that have been produced in the factory in Rio Gran do Sul are called foreign fire, the cement is called foreign mud, and the kerosene lamp invented by the Dutch in 1853 is called foreign lamp. Due to the lack of oil resources in Rio Gran do Sul, the price of kerosene lamps is relatively expensive, and ordinary Chinese rarely come into contact with kerosene lamps, and only in mining areas such as iron mines and coal mining fields are equipped with kerosene lamps.

The name that was produced by Westerners with a foreign character was mainly due to the curiosity of ordinary people about new things, and Li Mingyuan did not forcibly change the name of the people in this matter, and Li Mingyuan intended to give orders to the name of the new bicycle in the workshop that had been reasonably improved.

"Bicycle" looked at the new product that roughly conformed to the style of later generations, and Li Mingyuan blurted out a new term.

"Old Wangtou, since this product is the first one we have improved and produced, don't use the name of foreigners, I think it's better to name it a bicycle? Do you think it's a good fit? ”

"The product structure drawings were drawn by His Highness himself, so naturally they should be ordered by His Highness."

The old factory director said respectfully.

"Bikes? Will this guy move on his own? Seeing this strange-looking thing in front of him, a young Chinese soldier was surprised.

"Hehe, little brother has never seen a foreigner riding a foreign car, this thing can't move by itself, it needs someone to ride on it, look, it's like riding a horse."

A cavalry officer who had seen the bicycle of this era before made a gesture.

"Hehe, this brother is right, the bicycle needs a person to sit on it to move, but compared to riding a horse, riding a bicycle is much easier."

Li Mingyuan was in a good mood, introduced the common sense of bicycles to the surrounding Chinese, and then took advantage of the interest to ride the newly assembled bicycle directly to demonstrate it to the people in the factory.

The bicycle is easy to use, but it is a little difficult for people who have never touched a bicycle before, seeing Li Mingyuan riding a bicycle steadily in the factory yard, several curious Chinese officers also went up to try it once, and the result was naturally falling to the ground.

After the fresh energy of the people in the factory in the face of bicycles, Li Mingyuan once again explained to the old factory director: "Bicycle production should pay attention to strict confidentiality, except for the technical workers of the manufacturing plant and the people I allow to touch the bicycle, it is strictly forbidden to leak bicycle-related information, and the offender will be dealt with in accordance with military law." ”

"Your Highness can rest assured that the employees of Xinjing Machinery Manufacturing Factory will never leak any information about bicycles to the outside world."

The old factory director immediately expressed his position.

"Outside the factory, I will send additional troops to guard, the task inside your factory is to produce bicycles with all your might, by July next year, all the bicycles produced in the factory will be equipped with troops, your production task is very heavy, if there is any problem, you can tell it in advance."

"Starting production this month, with the existing manpower in the factory, we will be able to produce about 400 products a month, from the production of bicycle parts to the completion of assembly. By July next year, the total production of bicycles will reach up to 6,000. I wonder if His Highness is still satisfied with this production speed? ”

"Bicycles will come in handy in July next year, the number of 6,000 is too small, at least 10,000, how many people are missing in the factory, I will try to make up for you, can you complete the production target of 10,000 in July next year?"

"The smelting and forging of bicycle parts is the responsibility of the steel processing factory, as long as the factory over there can supply enough parts, and then two hundred skilled Chinese workers, the employees of the staff and the manufacturing plant will hurry up the production and will complete the production target issued by His Royal Highness in July next year."

The old factory director gritted his teeth and said.

"Okay, what is missing from the production bike, just come to me, I am not in Rio Gran do Sul, if you have any questions, you can also go to Minister Liu, they will also meet your needs."

"Your Highness!"

The old factory director saluted, raised his head behind him and continued, "Your Highness, do you want to take a look at another product?" ”

"Well, you two go in and move the big guy on the right outside." Li Mingyuan nodded slightly, and then ordered the two entourage soldiers to do things.

The two soldiers obeyed, and a few minutes later, a black iron guy welded from steel smelting was carried out to the courtyard outside the workshop.

"Your Highness, what is this thing for?"

"Hehe, you'll find out later."

Li Mingyuan said with a smile: "Old Wangtou, are the manpower for drilling ready?" ”

"It's all ready, just wait for your Highness to give the order and you can start."

"Well, let's get started."

Li Mingyuan opened his mouth to agree, the old factory director over there greeted, and the three Chinese workers took out five or six iron pipes more than two meters long from the workshop, and then drew a place of about one square meter in the open space in the courtyard, and the three of them dug the earthwork within the demarcated land range, and took about ten minutes to dig a small pit of about one square size and 40 centimeters, and the three of them took turns to operate auxiliary equipment to beat the iron pipe to the ground.

Seeing the operation of the three people, many of the Chinese present had a familiar feeling, although the operation method was different, but isn't drilling underground to obtain water?

In mainland China, the main way to obtain water is to dig wells, and the three people in the yard just insert a few thin iron pipes into the ground, how can the thin caliber of the iron pipe fit the bucket, and how to pump the water up from the well if there is no bucket?

The crowd who saw clearly the intentions of the three Chinese workers but didn't quite understand them watched silently at first, and then after a while, several officers who were close to Li Mingyuan boldly expressed the doubts in their hearts.

In the face of the half-ignorant crowd, Li Mingyuan only explained a few words, and only after the underground pipe was installed, and then the installed iron guy was fixed on the iron pipe, Li Mingyuan explained to everyone the working principle of the new product.

Another product produced by the machinery factory is the pressurized water well, which was very common in the countryside in later generations, and some places are also called foreign wells.

Li Mingyuan is not very clear about the specific invention time of the pressurized water well, only knows that the main principle of the pressurized water well involves the air tightness, so he thought of using rubber as raw material to make a waterproof and confidential hard rubber water pipeline and the rubber parts inside the pressurized water well to ensure air tightness, so he came up with the idea of manufacturing a pressurized water well.

Compared with traditional wells, it is more convenient to take water from the place where pressurized water wells are installed, and it saves the trouble of digging wells, which not only facilitates the daily water supply of ordinary Chinese, but also has more obvious advantages in agricultural development.

Rubber-soled cloth shoes, bicycles, pressurized water wells, in terms of industry, Rio Gran do Sul has a unique invention belonging to the Chinese,

These inventions not only made life easier for ordinary Chinese, but also brought considerable economic benefits to Rio Gran do Sul.

Looking at the groundwater pumped out of the pressurized well, Li Mingyuan's thoughts drifted to a more distant direction in the future.
