Jincao was originally the department in charge of coin, salt and iron affairs in the Prime Minister's Office. However, since the late emperor had set up the Salt and Iron Office, the power of salt and iron production is now controlled by the Yanfu. Later, the late emperor followed Cao Cao's example and set up the post of General Si Jin Zhong Lang, who was responsible for the casting of coins, farm tools, and weapons. Therefore, Jin Cao's power was further reduced, and now it seems to have become a prime minister's office used to supervise the manufacture of coins, salt, and iron equipment. department.
But this does not mean that Prime Minister Zhuge does not value Jin Cao. However, this is not because of the status of Cao Cao itself, but because one person is currently serving in Jin Cao.
At this moment, Yang Qing was worshiping him in his father's room and said, "Qing has seen a dandelion."
"Master Yang, there is no need to be polite. Please take a seat." The man hurriedly arranged the piles of silk books, bamboo slips, and wood and iron blocks on the low couch, and then smiled awkwardly at Yang Qing.
Yang Qing smiled and nodded, indicating that it was okay, and looked at the sundries piled aside by the owner curiously, and thought to himself: With such a diligent research spirit, he is worthy of being a famous and skilled craftsman in the world today.
After sitting down, he looked at the person carefully. The person in front of him had a ruddy complexion and dark skin. He was about fifty years old. He was dressed in rough clothes. His calloused hands were particularly eye-catching. He looked like a civil servant on duty. , more like an old farmer in the countryside.
"It will be easy to find Mr. Kerang next time." Yang Qing said with a smile.
"I wonder what Mr. Yang has to do with Yuan." Although the old man had seen Yang Qing once from a distance, the two had not interacted before. He didn't know what the new Mr. Yang, who had been in the limelight recently, wanted to do with him, so he could only wait for the visitor to tell him. Down.
Pu Yuan, a native of Basi County, is the most famous master craftsman in Sichuan, especially good at forging swords. After the late emperor entered Shu, Pu Yuan joined the then Zuojun shogunate and specialized in making weapons for the army. Once, the late emperor ordered him to forge a batch of Huanshou swords. He used superb steel-making technology to repeatedly fold and forge the iron material seventy-two times, and finally made five thousand Huanshou swords with seventy-two exercises. He greatly improved the equipment of the army, so he was highly valued by the late emperor and Prime Minister Zhuge.
Although the status of craftsmen at this time was not as low as that of later generations in the Ming and Qing Dynasties, they were still looked down upon by ordinary scholar-bureaucrats. Fortunately, Zhuge Liang himself was also good at tools and knew the role of agricultural and warfare tools in enriching the country and strengthening the army, so he brought Pu Yuanzheng into The Prime Minister's Mansion gave him the official position of Jin Cao. Of course, Yanfu and Jinfu are also competing to use such skilled craftsmen. In fact, Pu Yuan usually works in Jinfu. Therefore, Yang Qing came to Jincao many times but failed to find him. Fortunately, he met him today. On fire.
"Pugong, please take a look." Yang Qing took out two pieces of silk cloth from his arms and handed them over. Pu Yuan took the cloth and spread it out on the left and right sides on the table. He looked down and saw that there were two drawings of equipment. One seemed to be in the style of a plow, and the other seemed to be in the style of a rolling cart. He could see what they were in both pictures, but neither looked like the style in use today. He was confused and could only look at Yang Qing with doubts on his face, waiting for the person opposite to clarify his doubts.
Yang Qing stretched out his right hand and pointed at the silk cloth on the left and explained: "Sir, this is a plow made in the Qing Dynasty. Because of its curved shaft, it is called the Quzhou Plow Plow." Then he pointed to the right and said, "This is an improvement made in the Qing Dynasty. Rollover is lighter and more convenient than anything currently practiced in the world.”
It had been more than half a month since he took office. The responsibilities of the chief clerk had been clarified, and he had almost adapted to the work of the Prime Minister's Mansion. Yang Qing felt that it was time to build the overturning car and curved plow promised to Zhuge Liang. It was still October, and the winter wheat in Shu had not been sown yet, so it was time to try it out for large-scale use in the spring of next year.
Yang Qing also told Prime Minister Zhuge about this idea, and Zhuge Liang agreed and supported him very much. When he asked to find a skilled craftsman, Zhuge Liang recommended Pu Yuan to him. Originally, Yang Qing wanted to ask Zhuge Liang or Huang Yueying to participate in making plows, but he never recommended Pu Yuan. Only then did he think of this famous craftsman from the Three Kingdoms period. It would be better to have Pu Yuan to make the plows.
Pu Yuan's eyes sparkled after listening to Yang Qing's explanation. Although he is best at forging swords and weapons, he can also use farm tools. He understands the role of farming and warfare tools. At this moment, he heard that there are more advanced farm tools. He hurriedly said: "Please ask the chief clerk to explain it carefully."
"Pugong just calls me and makes it clear." Yang Qing took the opportunity to close the relationship between the two, and told Pu Yuan in detail the principles and advantages of turning carts and curved plows.
In fact, there are already long straight-shaft plows in the world today, but this kind of plowing is not only laborious to lift the soil, but also not very flexible when turning back, so the efficiency of plowing the land is not very high. The curved shaft plow changes the current long and straight shaft into a short and curved shaft, and installs a freely rotating plow disc on the shaft head. This not only facilitates U-turns and turns, but also makes the plow frame smaller and lighter. It enables people to operate flexibly and achieves the purpose of saving manpower and animal power.
The curved shaft plow consists of eleven parts: plowshare, plowboard, plow bottom, pressing mortar, plow head, plow arrow, plow shaft, plow tip, plow shaft, plow frame and plow disc. Compared with the previous ones, plow shaft and plow are added. establish. The farmer pushes the plow so that the plow arrow points downward and the plowshare penetrates deeply into the soil. If you lift the plow so that the plow arrow points upward, the plowshare will sink shallowly into the soil. The combination of the plow arrow, plow blade and plow construction of the curved shaft plow can be adapted to both deep and shallow plowing. The plow wall can not only break the soil, but also push the plowed soil to one side, reducing the resistance of the plow. , so that intensive cultivation can be achieved.
The rollover cart appeared in the late Han Dynasty. According to legend, it was built by Bi Lan, the official servant of Emperor Ling. Moreover, the rollover cart was only used to absorb water and spread roads, and was not directly used in farming. It turns out that in history, it was not until Ma Jun, a craftsman from the Wei State, that he improved the rollover that it became an agricultural irrigation machine. However, Yang Qing did not know the specific time when Ma Jun started the rollover. He thought it should be after Cao Rui succeeded to the throne, and according to the information he received, At this time, farmers in Wei State did not use turner irrigation, so he felt that there should be no problem in bringing out turner for future generations at this time.
The overturning car uses keel blades as chains, lying in a rectangular long trough. The body is tilted to the river or pond, and the lower sprocket and part of the body are submerged in the water. The sprocket can be driven by manpower, animal power, water power or wind power, and the blades move along the trough. The wiper rises and sends water out to the upper end of the long trough. In this way, water can be continuously sent from low places to high places, and it is simple to operate and easy to transport. It can be used for irrigation and drainage, and it is really a powerful tool for promoting agriculture.
Yang Qing made the design drawings seem specious based on his memory, but he still explained clearly the manufacturing and operating principles of the turning cart and the curved shaft plow. Pu Yuan is also a man of ingenuity. Although he is not good at making farm tools, there are pictures and explanations at this time. If you don't understand it, you can't be called a skilled craftsman. Moreover, once these two farm tools are made, they will greatly promote and benefit agriculture, and the reputations of the people involved will also be famous in the world. Pu Yuan also understands the benefits. As a famous craftsman in Shu, he also wants to make his reputation famous. The world, even as an individual, also wants to make the world pay attention to craftsmen, so it readily agreed.
Yang Qing didn't know what Pu Yuan was thinking. He was overjoyed when he saw that the master had agreed to make carts and plows. He stood up and thanked him: "Thank you for your help Pu Gong. I am really grateful." Pu Yuan saw Yang Qing, a famous scribe, like this. He respected himself and was moved in his heart. He quickly stood up and helped Yang Qing up, held his hand tightly, and solemnly said: "I will do my best to do it."
