Three Kingdoms: Ancestors of the Han Dynasty

Chapter 72 New Farming Methods
Liu Chan and others cultivated only 3 mu of paddy fields in Wudan Mountain (later generations 2 mu), and with the help of many males, they quickly harvested it.

In the past few days, Fei Yi took the lead in weighing the harvested rice and found that 3 acres of land yielded 46 dendrobium grains per mu, with an average harvest of 15.3 dendrobium grains per mu. At that time, everyone at the scene couldn't help but gasp.

The yield per mu has greatly exceeded the highest yield per mu of 10 Dendrobium during the Three Kingdoms period, and reached the average yield of rice per mu in the Tang Dynasty.

During the Wei and Jin Dynasties of the Three Kingdoms, such as Ji Kang's "Health Preservation Theory" recorded the yield: "One mu and ten dendrobiums are called fertile fields, and this is a common name in the world."

If one Han mu of land can harvest 10 Dendrobium grains, it is high-yielding, and 1.5 Han mus of land is equal to the current harvest of 1 Dendrobium per city mu.

How much was 15 Dendrobium at that time? 1 dendrobium weighs 6 kg and can hold 90 kg of rice.

In other words, the high-yield fields in the Wei and Jin Dynasties could achieve 1 kilograms per mu per city, while the average yield per mu per city in the Tang Dynasty could reach 90 kilograms.

Fei Yi was dumbfounded, 3 kilograms of 276 dendrobium grains in 46 mu of land, which is equivalent to the current highest grain yield of 4.5 mu, and His Majesty's new farming method has increased the yield so much.

Fei Yi was in a hurry, holding a rice stalk, and ran all the way to Shuhan Xingong to inform Liu Chan.

Liu Chan, who was checking the official documents, heard Fei Yi's announcement, so excited that he didn't have time to put on his shoes, so he threw down the official documents, and dragged Fei Yi all the way from the palace to the prime minister's mansion, ignoring the call from the maid behind him.

Just as the guard at the gate wanted to salute, Liu Chan pushed him away. Liu Chan just wanted to share the best information with his father-in-law.

"Father Xiang, I'm overjoyed! I'm overjoyed! I'm overjoyed! I harvest 15 hu grains per mu."

Liu Chan, barefoot and disheveled, dragged Fei Yi, who was dressed in commoner clothes, through the prime minister's residence.

What is etiquette, and can there be more important than that?
Liu Chan and Fei Yi no longer cared about the image of etiquette. Liu Chan, who had already integrated into the Three Kingdoms, did not know what significance it was for the Shu Han from 10 to 15 dendrobium grains.

Perhaps it is indifferent to the people of later generations, because of the existence of Yuan Lao, who has a yield of thousands of kilograms per mu, so they have no feeling for the increase of 30 kilograms.

Many officials in the inner mansion heard Liu Chan's shout outside, and they flocked out like people eating melons in later generations, wondering what made His Majesty, who was always stable in the past, so rude.

Zhuge Liang, who was discussing with Yang Hong about sending troops to guard Dujiangyan as the weir officer, heard the noise outside and frowned a little, dissatisfied that someone was making such noise outside.

Liu Chan dragged Fei Yi directly into the meeting hall. Liu Chan was sweating profusely, out of breath, and excitedly said to Zhuge Liang: "Father Xiang, I cultivated fields in Wudan Mountain. I harvested 15 dendrobium grains per mu, and a total of 46 dendrobium grains per mu. "

Zhuge Liang, who was originally dissatisfied with Liu Chan's disrespect, hurried up and asked, "Is it true?"

"It's true! This method is what I read in ancient books when I was young. When I was farming, I recalled farming according to the book. As expected, the harvest per mu was so much. Although there is no book, I have ordered Fei Yi to do it after farming. Write down the main points, and I asked Fei Yi, Dong Yun, Liao Li and others to write a new book based on "Book of Si Sheng" and "Monthly Order of the Four People" for the officials in central Shu to read." Liu Chan calmed down and tidied his clothes , Put on the boots and shoes sent by Gong'e later.

Zhuge Liang led Liu Chan and Fei Yi to sit down and asked Fei Yi to explain the main points.

Fei Yi sat down and wiped the sweat from his forehead, and said slowly: "At this time, we need to start with His Majesty ordering ministers to make rakes and farm tools..."

Liu Chan knelt and sat on the middle stage, drinking the clear water offered by the maid to quench his thirst. Looking back on the knowledge of later generations, he secretly sighed that the yield per mu could be increased. Liu Chan looked up rice papers in his previous life and vaguely remembered that the average yield per mu in Tang Dynasty was 138 kg; the average yield in Song Dynasty was 225 kg. The yield per mu is 333 kg; the average yield per mu in the Ming Dynasty was 470 kg; the yield per mu in the Qing Dynasty was [-] kg.

Even if it is not as good as the yield per mu in the Ming and Qing Dynasties, there is still hope that the yield per mu in the Tang Dynasty will reach that of the Tang Dynasty, because although the quyuan plow and plow-harrow-plow land preparation techniques appeared in the Tang Dynasty, they were really promoted on a large scale in the Song Dynasty .

It is not surprising that the farming on my side adopts the plowing-harrowing-soil preparation technique of the Song Dynasty, and also carries out seedling cultivation and transplanting. It is not surprising that the average yield per mu of the Tang Dynasty has been reached.After the implementation of Dahan, the common people may not be able to harvest 15 dendrobium grains per mu, but it is still entirely possible to harvest 12-14 dendrobium grains per mu. (Worried about someone spraying, write conservative T_T!)
If after the reunification, Zhan Chengtao was introduced into the Han again, and then the double-cropping rice yield per mu was implemented, then it is entirely possible that the yield per mu would be close to that of the Song Dynasty, or even exceed it.

"If our Han Yizhou can implement this new type of farming, the common people can get 12-14 dendrobium grains per mu, which will also greatly enhance our national power." Zhuge Liang's expression overflowed with excitement.

Yang Hong was also stroking his beard and laughing, completely forgetting that he had just discussed with Zhuge Liang about setting up weir officials in Dujiangyan.

Liu Chan, who had regained his composure, rolled up his sleeves and looked around the crowd and said, "Agriculture, Zhuqing, is the foundation of my great man, and it has a great bearing on it. The rebellion in Nanzhong was originally due to the suppression of the rebellion this year, and it is all due to the empty treasury. I am afraid that Xia Geng will not be in a hurry this year. But I have to promote new farming methods and new farm tools in the second half of the year, in order to promote them in Dahannei County in the spring of next year."

"Fei Qing, you can cooperate with the other servants. You can first write down the farming method and hand it over to the Prime Minister, so that the Prime Minister can promote the Shuzhong plow and other new farming tools; "Yue Ling" is suitable for Yizhou's agricultural new book, which can be written later." Liu Chan instructed Fei Yi to say.

Fei Yi bowed his hands and promised, and stepped down to work.

Zhuge Liang returned to official duties and discussed with Liu Chan and Yang Hong about setting up weir officials in Dujiangyan.

Yang Hong, who has been transferred to the prefect of Shu County, arched his hands and said: "Du'anyan (Du'an County here) was set up in the later Han Emperor Lingdi before the "Dushuizhu" and "Dushuichang" were responsible for the maintenance of the head of the weir. Can the weir officer be like the past?"

Zhuge Liang didn't answer directly, but pointed to the map of Du'anyan and said, "There are three important things in Du'anyan: Yuzui dike, Feishayan spillway and Baopingkou water inlet."

"In the Qin Dynasty, Li Bing built Baopingkou in order to open up Yulei Mountain so that the Min River could flow to the east. This time, the river water in the west would no longer flood; Fertile land. The site is prone to scour and rock accumulation and needs occasional maintenance.”

"Due to the high terrain in the east of the river, it is difficult for the river water to flow into Baopingkou. Li Bing also built a fish mouth dike to divide the river into two branches: one goes down the river, and the other flows into Baopingkou. But the affairs here are not the most important. It's important." Zhuge Liang pointed to the dike and said slowly.

"The most important thing is the flying sand weir at the tail. The flying sand weir needs to adjust the amount of water when it needs it. When the water level in the Neijiang River is too high, it needs to adjust the top of the weir to a suitable position so that the amount of water entering the treasure bottle mouth cannot be too large. Big...but there will still be silt, which needs to be cleaned up on time." Zhuge Liang pressed his finger on the map Feishayan and said to Yang Hong.
