Chapter 218 The Holy Tree Appears in front of People (Please Subscribe!)

In order to have a real armored battleship, Zhu Kezang was ready to exchange it for a good thing.

That's the rubber tree!

What would it mean for the new Ming Empire if rubber trees appeared?

It means that the industrial era will be upgraded!

Rubber can be widely used in various industries.

For example, the soles of the shoes we wear every day are made of rubber, which can also be used to produce contraceptive tools and effectively control the population!

If there was rubber, Zhu Kezang could develop a bicycle. The most critical factor of a bicycle is the tires.

The earliest tires were made of wood and iron. When humans discovered rubber, they made tires out of rubber, but at that time they were still solid rubber tires.

Until British veterinarian Dunlop improved the tires, his son liked riding bicycles very much, but because the tires were solid, it was very uncomfortable to ride. Dunlop, who felt sorry for his son, had an idea and pumped air into the tires to make them more elastic after expansion.

So in 1888, the world's first rubber hollow tire was born.

Soon, this kind of tire became popular among people, and in 1895, the world's first car using pneumatic tires came out.

If Zhu Kezang were more radical, he could develop internal combustion engines, occupy North America and the Middle East, exploit oil, and develop the automobile industry.

However, at this stage, Zhu Kezang felt that the steam engine was sufficient.

From the Spaniards' discovery of rubber to the Americans' discovery of rubber vulcanization, the span of more than two hundred years was once again bridged by Zhu Kezang.

Zhu Kezang remembered that although unvulcanized rubber is very tough, it is not wear-resistant. It can be made into rubber balls and erasers, but it cannot be made into tires.

The Goodyear family also found a golden job and is still famous for its rubber tires to this day.

In fact, it is communicating with the system.

By the way, you must not exchange oak saplings or oak seeds, because it takes seven or eight years for an oak tree to grow to produce gum!

【Human presence detected, do you want to redeem? 】

First of all, Luzon conquered the territory early, so it was relatively safe and there was no fear of being destroyed by the natives.

Secondly, Luzon will be a region rich in rubber in the future.

Zhu Kezang’s destination is the Zamboanga Peninsula in the Luzon Protectorate!

Therefore, as soon as rubber appeared, Daming could save a lot of time in the practical promotion of rubber and directly start vulcanizing rubber and researching excellent formulas.

However, the Ming Dynasty's steam engines relied on tight welding and some earth-made sealing materials for sealing. The workmanship was very troublesome, and problems would still occur after they rusted.

【yes!】

It is important to choose a place with a climate similar to that of the Amazon basin in South America!

Zhu Kezang planned to plant it first on the southern island of the Luzon Protectorate.

However, the rubber yield of these plants is relatively low, and the plant that can truly satisfy 98% of the world's industrial rubber sources is a plant called the hevea tree.

It wasn't until 1839 when American Charlie Goodyear discovered that heating sulfur and rubber together could enhance the elasticity and strength of rubber, did rubber gain industrial practical value.

If planted in Nanyang, it only takes 7 years to produce rubber. If planted in Qiongzhou Island, Guangdong and Guangxi, and Yunnan, it will take 8 years.

Everywhere is empty and there is nothing interesting to see.

The rubber tree is temporarily sealed in the system space, and can be buried when Zhu Kezang finds a treasure place.

When he was a child, his parents often went to the tire factory workshop to observe. Zhu Kezang knew everything about the production of rubber tires and has never forgotten it to this day.

In order to plant rubber trees, the Luzon Protectorate organized many indigenous slaves to cut down the original trees on the land to make room.

The rubber tree is native to the Amazon River Basin in Brazil. More than 1,000 years ago, people discovered that after the bark of the rubber tree was cut, white latex flowed down. At that time, the ancient Indians had learned to use some primitive methods to extract rubber and make some products.

, such as playing with bouncy balls, they also found that applying rubber to clothes or feet can make them waterproof.

However, there are certain considerations when exchanging rubber trees.

In the future, Zhu Kezang will definitely have to go to the Americas to find a place for the Ming Dynasty, otherwise he will not be worthy of his status as a time traveler.

Only the people of the Ming Dynasty had to be compensated for their land expropriation, and the indigenous people did not need to worry about it.

Soon, the scene was filled with golden light, and people vaguely saw the shadows of a bunch of trees!

When the golden light disappeared, they were frightened by the scene in front of them!

Another example is the Eucommia ulmoides tree, which is unique to China. Rubber can be extracted from its seeds, leaves and bark.

Because there are as many as 2,000 species of plants containing rubber in nature, but not many are truly valuable for collection. Rubber can currently be extracted from 500 species of plants, including the familiar dandelion.

What if there were indigenous people living here?

They will all be driven away. If they don't accept it, they will be shot.

Once there are trees, we can’t just plant them on Yizhou Island!

Because planting rubber trees is also a science, such as site selection.

The Hevea Hevea tree is also called the Brazilian Hevea tree, or the Rubber tree for short. Compared with other gum-containing plants, it has two decisive advantages. One is that the tree is tall and contains a lot of gum.

In addition, Zhu Kezang's parents in his previous life were employees of a state-owned rubber tire factory. They spent all day watching the price trends of natural rubber in Siam, Malay, Hainan, Yunnan and other countries.

After a week of preparations, Zamboanga finally built its first rubber plantation.

It is better to plant rubber sooner rather than later. The industries of Ming Dynasty are waiting for rubber.

Zhu Kezang knew that the Nanyang region was the first stop for rubber migration, and judging from the experience of later generations, the amount of rubber produced in various places in Nanyang exceeded that of the place of origin. It can be seen that Nanyang is very suitable for the growth of rubber trees. Plant early and get rich early.

Suddenly, Zhu Kezang shouted: "Quiet!"

"Preparing the ship, I am preparing to inspect the Luzon Protectorate."

Looking at the empty land, Zhu Kezang prepared to do a flower show and show himself to the people!

If he had waited so long, Zhu Kezang would have been able to transport rubber trees back from South America long ago!

Zhu Kezang planned to replace a thousand eight-year-old rubber trees first, the kind with fruits, so that they could produce glue and even out the seeds, so as to plant more rubber trees!

【50 points deducted】

Second, it has a long lifespan. A tree can continuously provide rubber to humans for three to forty years.

If you cut off the stem of a dandelion, some white liquid will be secreted inside. If you touch it with your hand, it will feel sticky. This is rubber.

Then, he raised his hands and closed his eyes, as if performing some kind of ritual.

There were many Luzon officials, Luzon businessmen, and Luzon Chinese at the scene. They didn't know why the emperor called them here to observe.

America is really full of treasures, with fertile land, protection from two oceans, and various high-yielding food crops and cash crops.

The open space in front of me turned into a forest, and these strange trees were actually rooted directly into the ground, as if they had grown here originally.

In such a scene, everyone immediately knelt down. Is this emperor really a god?

The atmosphere was heightened, and Zhu Kezang took advantage of the situation and said with dignity: "This is a sacred tree. It will definitely benefit the Ming Dynasty. The Luzon Protectorate must protect it with all its strength!"

The eyes of everyone at the scene looked at him with enthusiasm!
