Datang Nongsheng

Chapter 170
After talking about iron, of course Sun Xiangfu wanted to talk about the crystal mine.

"Have you seen the crystal mines unloaded from the ship? After melting, I made a few more sets according to the wooden mold I asked the carpenter to carve. There are also copper sleeves, all big and small. As for the flat ones For the crystal mirror, if there are extra ores, it is enough to make two or three sides."

In fact, glass can be fired with sand. Unfortunately, Sun Xiangfu is not a science student. This thing can only give Ma Lin and Zhang Quan a direction to explore by themselves.

After the crystal ore is smelted to remove impurities, pure and transparent crystals can be obtained properly. They can be made into concave-convex mirrors, which can be used as telescopes. They can be made into flat crystals. As long as one side is brushed with mercury or metal silver and platinum, it can be made into a mirror. Of course, later generations have widely adopted the method of aluminum vapor deposition to produce higher-quality mirrors, but there is definitely no condition to meet this production method at the moment.

The craftsmen have never doubted the research direction proposed by Sun Xiangfu, because past experience tells them that they can succeed in the end.

With a telescope to observe celestial bodies and sea levels, the accuracy of the sextant will be higher. Of course, it is also of great benefit to use this thing in the military during this period. Sun Xiangfu only asked everyone to make things, but did not let them They were assembled, and he had to complete the final process by himself. Also to save his life, he needed to keep one or two treasures on his body. In case Li Shimin wanted to kill him, he might escape death if he released them.

Talking about technology research and development is endless, but after half a day, Sun Xiangfu has almost finished explaining what he wants to explain, but everyone is unwilling to leave.

"Why, do you have anything else to do?"

"Well, village chief, in the future, can we call ourselves farmers' children?"

"Nongmen?"

Mentioning this, Sun Xiangfu covered his forehead and remembered the story he told Yu Xiu'er a few days ago when he fooled Yu Xiu'er. Now the group of his subordinates have read some enlightenment books, and they have become smarter and solved the problem. After the problem of food and clothing, what they followed Sun Xiangfutu was to learn their own skills and pass them on from generation to generation.

Now, Li Shimin has ordered that the book "Qimin Yaoshu" be listed as a must-read for local officials, and the author Jia Sixie's establishment of agronomy has also been made public. Of course, the purpose is not only to let the ruling The local officials here know better about farming and production, and they also want to let everyone understand why they didn't kill Sun Xiangfu, the fourth generation descendant of the farming family.

However, there is a book in Nongmen that is a must-read book for officials. After the founding of the country, although the military style prevailed and Confucianism was not respected as much as in the later Song and Ming Dynasties, Confucianism was still the unshakable mainstream. However, Li Shimin praised agricultural books as high as Confucian classics, but there were not many people in the court.

Because there are examples here, not to mention those courgettes and cotton, the wheat whose yield per mu has nearly doubled was grown by Sun Xiangfu, a farmer!The rice with an yield of ten stone and three per mu was grown by Sun Xiangfu, a farm boy!
In ancient times, all countries were based on agriculture. Who would dare to disrespect the classic "Qi Min Yao Shu" that can greatly improve agricultural production?
Therefore, in Chang'an recently, "Qi Min Yao Shu" is still hard to find, and the word "nongmen" is also widely circulated among the people. The popularity rate is very high, there is no way, star halo!

"Well, you have learned some skills from me, so it's okay to call yourself like that, but since you have entered the farming school, you must remember the rules of the farming school, take the development of agricultural production as your own responsibility, and devote yourself to the farming cause of the Han people." Sun Xiangfu seemed to be very stern.

Hearing this, several people in the cell knelt down one after another and solemnly kowtowed to Sun Xiangfu. From then on, they were also regarded as one of the fifth generation successors of the Nongmen.

Moreover, this is not over yet. The next day, when Yu Xiuer came to deliver meals to Sun Xiangfu, she brought all the children from Xingfu Village. Their cotton clothes, chests and backs were all written with black vegetable dye. When they came to the cell with a big Nong character, they bowed down when they saw Sun Xiangfu.

"Uh, Xiu'er, is this the song you sang?"

Seeing this scene, Sun Xiangfu said in a daze.

"This is Grandpa's idea. He said that if you do this, even if His Majesty has all kinds of reasons, he will not be able to kill you."

Hearing this, Sun Xiangfu was taken aback for another moment, and then understood in his heart.

The Tang Dynasty was based on agriculture, and clearly advertised Sun Xiangfu as the contemporary head of agronomy. Unless the emperor wanted to deny farming and rejuvenate the country, otherwise, Sun Xiangfu, the head of the family, could not be easily executed, let alone Sun Xiangfu. But his attainment in agriculture is unique in the world, and he has real achievements. The new rice seeds will benefit the people all over the world. If he doesn't want to lose the support of the farmers all over the world, Li Shimin must not kill him.

"Okay then! You little fellows, you can be regarded as the fifth generation of official disciples of my Nongmen! Remember, our Nongmen disciples must know how to farm. After returning, each choose a test field, three kinds of crops, and sow the seeds in person. Farming, wait until I come out one day, and check your homework."

Sun Xiangfu, who was wearing shackles, was worshiped by the little guys. To put it bluntly, the craftsmen like Wang Fu and Wang Gui just got a little bit with Sun Xiangfu. Sun Erli, who has the highest level of farming, also because of Insufficient cultural foundation will soon lead to bottlenecks. Agricultural technology is not just some physical work. It is plant science and technology. It is possible to go further and further on this path of plant science.

Therefore, in the future, those people in Xingfu Village will only contribute more energy to farming and help Sun Xiangfu spread his mature planting experience. It is these little guys who really research and innovate, and Sun Xiangfu will also Pass more science on to these little guys.

"Brother, I want to choose Lingnan as the experimental field."

After all the little guys saluted and stood up, Sun Deshou spoke first.

"Choose Lingnan? Why?" Sun Xiangfu called him over and asked.

"There are a lot of fruits in Lingnan, and there are also elephants. I want to raise one too..."

Sun Xiangfu, who was just about to teach these little guys all he had learned, instantly recognized the fact that they were still children at heart and couldn't afford so much. Prestige is why I want to go to Lingnan, and the fruits in Lingnan are really sweet.

"Go if you want! Big brother built a house over there, and there are a lot of fields. It is also a good choice to spend winter in Lingnan every year in the future." Sun Xiangfu said speechlessly.
