Jiaozhou and Yazhou are the southernmost territories of Datang, the climate is warm and humid, is the most suitable environment for the growth of rubber trees, planting rubber trees in Jiaozhou and Yazhou, is undoubtedly the most suitable choice, only a few years, Datang can have a steady stream of rubber resources, thereby greatly promoting the development of industry, improve the living standards of the people. Pen, fun, and www.biquge.info

In addition, with the large-scale application of rubber resources in the future, there will definitely be many people who choose to establish rubber plantations, so as to earn money to make a living, so that the rubber resources will be more sufficient in the future, and the cost will be reduced step by step, which is more beneficial to the industrialization process of Datang.

As for the collection of rubber and the manufacture of rubber products, only Ang Lee has certain skills, that is, all this must be done under Ang Lee's guidance, and without Ang Lee's careful guidance, everything cannot be carried out.

Yazhou is lonely overseas, you need to take a boat to arrive, it takes a lot of time to go back and forth, and the situation in Yazhou is similar to that of Jiaozhou, the climate is basically the same, it is a warm and humid environment, after the inspection in Jiaozhou, you can understand the situation in Yazhou, there is no need to run more.

Juvenile rubber trees cannot be tapped, otherwise it will seriously affect the growth of the saplings, and the yield that can be obtained by forcibly tapping rubber is also very limited, so it must wait for many years.

The big rubber trees that have been fully viable can be used for rubber tapping, and they have been rooted in Jiaozhou for several months, or even more than half a year, and have fully survived and can produce rubber.

After a brief inspection of some rubber trees, Li An was very satisfied with the official in charge of the rubber plantation in Jiaozhou, and praised him on the spot, asking him to make persistent efforts to make the rubber plantation bigger and better.

Next, Li An will start the relevant preparations for the rubber tapping operation, and needs the technical personnel of the church to Jiaozhou, so that they can study carefully, tap rubber every day in the future, and deliver a batch of rubber raw materials to the capital every once in a while to meet the needs of the capital's industrialization.

"Li Shilang, these things are so strange, what are they for?"

When Li An took out the tools he brought from the capital, the relevant technical personnel in Jiaozhou were all dumbfounded, they had never seen such a strange tool, and of course they didn't understand what it was for.

The tools were very simple, a sharp cutter, a small drainage trough, and a conical container for the rubber sap, and a wire to tie the conical container to the tree, and that was as simple as that.

"These things are the necessary tools for cutting rubber, and with them, we can cut the rubber juice we need."

Li An took these tools and opened his mouth to introduce.

"Oh, it turns out that these are treasures, and they are used to cut rubber."

Everyone nodded in understanding.

"Li Shilang, then let's open it now or cut the rubber!"

There are already people who can't wait to see what the rubber juice looks like.

Li An shook his head with a smile and said: "Not yet, the best time to tap rubber every day is in the early hours of the morning, only in the early morning, the rubber cut out is the best and the most, so tomorrow you have to get up early, and you have to come over at three o'clock, and the official will personally demonstrate so that you know how to cut rubber." ”

When everyone heard this, although they didn't quite understand it, they only obeyed in front of Ang Lee, and obediently went back to rest.

"Li Shilang, why do you want to tap rubber in the early hours of the morning? It's the most sleepy time of the day, so why not change the time? ”

After everyone left, Guo Yan asked curiously.

"Of course not, in the middle of the day, only in the early hours of the morning, is the best time, because the rubber tree after a night of rest, in the early hours of the morning is the time when the sap is the most, can collect more sap, and once the sun rises, the rubber sap that flows out is easy to solidify, so that the rubber sap can not be collected."

Ang Lee opened his mouth to explain.

"Oh, I see, but it's still dark? You have to hold a torch to see it! ”

Guo Yan opened his mouth and muttered.

Li An thought for a while, and said: "Guo Lvshuai, didn't we come this time, didn't we bring a set of generator sets, immediately move into the rubber plantation, and pull the wires, hang a thousand light bulbs, we must ensure that when the sun is shining tomorrow, the rubber plantation can see the road, this matter will be handed over to you, go quickly!" ”

"Yes, Li Shilang."

Guo Yan responded and immediately went to prepare.

After sending Guo Yang away, Li An also returned to his temporary residence by car and immediately began to rest, after all, he would have to get up early in the early hours of tomorrow morning to tap rubber, and he could only get up early when he went to bed early.

"Li Shilang, it's already two o'clock."

When Li An was sleeping in Zhengxiang, Guo Yan's reminder came from his ears.

"What, it's been two minutes, so fast."

Li Ang hadn't woken up yet, but the time he had set had to be observed, so he immediately got up and drove to the rubber plantation.

When Ang Lee arrived at the rubber plantation, it was already four quarters of the hour, that is, Ang Lee was late, and he was a whole moment late.

But Ang Lee is a big leader after all, so even if Ang Lee is late, no one dares to say anything, this is the privilege of leaders, and it has been the case since ancient times.

"Hehe, everyone has already arrived, and no one is late."

Li An praised everyone, then looked up at the electric lights above the rubber plantation, and praised: "The electric lights are also very well arranged, and this large area is lit up, but where the electric lights are not clear, you still have to use torches." ”

"Li Shilang, the torches are all ready, enough to use."

Li An nodded with satisfaction and said, "Okay, let's start tapping rubber now, and bring all the tools." ”

Soon, several tools were taken and handed over to Ang Lee.

Li An took matters into his own hands, first tied the conical container to the trunk of the rubber tree with iron wire, and then used a sharp cutter to cut a scratch on the trunk of the rubber tree obliquely, this scratch should have enough depth to ensure that the juice flowing out can go down the scratch without missing it, and at the lowest point down a distance, embed a metal diversion groove, so that the rubber juice left on it can flow down the diversion groove into the bottom conical container, so as to harvest the rubber juice.

When Ang Lee had done all this, suddenly, a gurgling stream of milky white juice was left along the scratches and dripped into the conical container below through the metal diversion groove.

"Oh, that's the juice of rubber! It looks a lot like milk! ”

"Is this juice really very useful?"

"Li Shilang said that this thing is useful, then there can be fake, this milky white thing must be a good thing."

"Yes, yes, it's definitely a very good thing, I just don't know how to use it."

When everyone saw the milky white rubber juice, they were all very excited, and they couldn't wait to do it themselves immediately to experience the pleasant feeling of cutting rubber.

"You see it! That's how the rubber is cut, every day at this time to start tapping, to start collecting glue at the time of the hour, that is, to pour the liquid in these conical containers into the vats, it's that simple, do you understand? ”

Ang Lee asked loudly.

"Li Shilang, we understand, understand."

Li An nodded and said: "The official has already demonstrated, and next, it is time for you to learn and practice, you also saw just now, cutting rubber is so simple, the official has limited time, you must learn it immediately, let's start!" ”

Under Li An's order, the technical officials and dozens of craftsmen began to pick up tools and work on the rubber tree.

Everyone began to tap rubber, while Ang Lee patrolled back and forth, and immediately guided those who found that they did not do well, and praised those who did well on the spot.

Because rubber tapping is really very simple, there is almost no technical content, and there is no such thing as not being able to learn, so everyone performed quite well, and almost all of them were able to cut the rubber tree in place according to the requirements put forward by Ang Lee, and harvested drops of rubber juice.

After affirming their experience, Ang Lee asked them to continue cutting rubber until all the 1,000 rubber trees in the area were cut.

Due to the large number of manpower, soon, more than 1,000 rubber trees began to produce rubber, and it was very spectacular to look at from afar.

During the time when the rubber trees are producing rubber, only a few people need to be sent to patrol to make sure that all the rubber trees are producing rubber and that no rubber sap is missing.

And Ang Lee also used this period of time to explain more knowledge about rubber trees to everyone, so as to help increase the yield of rubber trees in the future.

After all, the rubber tree is also a tree, but also needs to be carefully cared for, when picking rubber, we should also pay attention to the scientific method, can not for the so-called short-term interests and loss of the vitality of the rubber tree, so is to exhaust the fish.

Ang Lee's explanation lasted for more than an hour, until the sun showed the white of the fish's belly, and he immediately ordered everyone to do their work to collect the rubber juice in the large wooden barrel.

"Li Shilang, I really collected a lot! I tried it just now, and it was more than 100 catties. ”

Guo Yan put down the big wooden barrel and said excitedly.

Li An nodded and said happily: "The yield is indeed good, but such a small output is far from meeting the needs of my Datang, and it is necessary to continue to transport rubber trees from the Americas, and in addition, rubber saplings must continue to expand the planting area." ”

"Li Shilang rest assured, we will definitely continue to work hard to breed more rubber trees."

The official in charge of the rubber plantation said seriously.

Li An looked at the rubber in front of him, and ordered: "The mining method of rubber trees, you should have mastered it, however, rubber trees cannot be mined every day, they must be mined once every two or three days, the method is the method that this official just taught you, now, the train from Jiaozhou to Luoyang City has a daily departure, in the future, as long as the rubber is mined, it must be transported to the capital by train immediately, do not delay for a moment, understand no." ”

"Yes, Li Shilang, I'll understand."

Everyone hurriedly answered.

Now the rubber trees here in Jiaozhou, every two or three days can produce a hundred catties, this output is too little, however, Yazhou has planted more adult rubber trees, the output is estimated to be twice that of Jiaozhou, so that the capital in the short term, can get an average of 100 catties of rubber juice per day, although it seems a little less, far from meeting the needs of the Tang Empire, but there is better than nothing, first use these small amount of rubber resources to develop science and technology, after the technology matures, the rubber planting industry of Datang has also developed, so, The quantity is sufficient.

Now that the task of cutting rubber has been arranged, there is no need for Li An to continue to stay in Jiaozhou, he still has to rush back for the New Year? If you return to the capital now, you can go home before the Chinese New Year, so as to achieve a family reunion during the New Year.

After emphasizing the cutting of rubber, Li An immediately made the decision to return to the capital, and took away the 100 catties of rubber juice that had just been harvested, and prepared to take it back to study various rubber products.

After the train departed, Ang Lee built a test bench in his sleeper car and tried to use heating to see what kind of changes would happen to rubber products.

The process of experimentation was boring, but Ang Lee was very adaptable to it, and soon discovered some rules, combined with the knowledge of his previous life, and the preliminary results came out.

The train drove for three days before arriving in Chang'an City, and Li An studied on the train for three whole days, and achieved a series of important results, many results, even Li An himself felt a little surprised, after all, the test bench on the train is so simple, and it is really surprising to get such a high test effect.

After returning to the capital, one percent of the rubber juice that Li An brought back had been used up, and ninety percent was still intact.

In order to achieve the simplest results as soon as possible, Ang Lee was the first to return to the R&D center and arranged for craftsmen to rush to make various instruments, make some simple and usable things, and put them into use immediately.

Ang Lee first made a pair of rubber soles, and then, he made a pair of rain boots, both of which are very practical things for everyday life.

The rubber sole and sturdy fabric quickly made for a pair of lightweight, sturdy shoes that were very practical, and the rain boots were quickly manufactured.

Of course, due to the experimental nature, the rubber shoes and rain boots made by Ang Lee are all made according to the size of the soles of his feet, that is, these are the rubber shoes and rain boots made by Ang Lee for himself.

Wearing rubber shoes, Li An felt that walking was much lighter, and the soles of his feet were soft, and he was no longer afraid of walking too much, and his feet hurt.
