There is no doubt about the craftsmanship of the military craftsmen.
Several military craftsmen worked together, divided the labor and worked together, and it took about half a day to complete it.
It is an experimental product in itself, so it does not need to be so harsh, and there is no need to consider long-term use.
The straight shaft is changed into a curved shaft, and the big plow is changed into a small plow.
The first Quyuan plow was born in this era.
"Let's give it a try!" Wang Li was even more excited than Zhao Si and urged the soldiers to put on the cattle for experiments.
For comparison, start plowing directly next to the straight shaft plow.
On one side is a straight shaft plow carried by two oxen, and on the other side is a curved shaft plow pulled by a single ox.
Under Wang Li's orders, a total of three old cows began to move with heavy steps.
Zhao Si and Wang Li followed behind and observed carefully.
Lao Niu walked around for a long time, and Zhao Si followed silently to observe the depth of the soil.
At a distance of about a hundred meters, Zhao Si observed that the difference in the depth of the soil eaten is not very big. In comparison, the straight-shaft plow eats soil deeper, but the depth fluctuates greatly. If it encounters a boundary with relatively hard soil, Or there are clusters of rhizomes that make it easier to float.
The curved shaft plow's soil intake is slightly shallower, but the soil intake does not fluctuate much. Compared with the straight shaft plow, it is obvious that the force is more balanced and the power transmission is more stable.
In terms of speed, the curved shaft plow did not beat the straight shaft plow. On the contrary, the straight shaft plow was faster.
After plowing until the field turned, Zhao Si looked back and found that the traces of the straight-shaft plow were straighter.
When it comes to turning, it is obvious that the light curved shaft plow saves more effort to turn around, while the long straight shaft plow requires a lot of effort, after all, the weight is here.
After going back and forth, objectively speaking, the curved shaft plow did not beat the long straight shaft plow, and Zhao Si frowned.
Even Wang Li asked curiously: "I think this curved shaft plow doesn't seem to be faster than the straight shaft plow."
Not only was it not as fast as the straight-shaft plow, it was also more than a quarter slower.
Zhao Si was thinking about what went wrong when he found a group of military craftsmen approaching with happy faces.
The craftsmen of this era may not understand the so-called scientific principles and cannot explain them.
But they are experienced farmers and qualified craftsmen. Compared with Zhao Si, a modern person who has basically never farmed, they keenly grasp the advantages of Quyuan plow.
"This plow is very good! This plow is very good!"
Several craftsmen gathered in front of the curved shaft plow, carefully observing the difference between it and the straight shaft plow, while praising it.
"What's so good about it? It seems like it's not as fast as a straight shaft plow?" Wang Li asked.
"General, this plow is small, and it only requires one person and one oxen. Naturally, it is not as fast as two oxen carrying the plow. It has just been plowed, and the plow marks on the ground are the same depth. One oxen is carrying the plow, so the speed is naturally not as fast as two oxen carrying the plow. The soil is not deep enough. Because the plow is too small, if it were larger, it would eat the soil deeper and faster than a straight-shaft plow."
The military craftsman opened his mouth to explain, and Zhao Si suddenly understood.
The curved shaft plow made this time was only half the size of the straight shaft plow, because Zhao Si followed the memory in his mind.
Times and times are different.
During the Qin Dynasty, even a straight-wheel plow was a luxury product, and ordinary people still used the traditional farming method.
After the Han Dynasty, the long straight shaft plow gradually became popular.
It was not until the early Tang Dynasty that the Changqu Yuanli came into being.
At this point, the long straight shaft plow was completely eliminated.
Under the same size, the performance of the curved shaft plow completely surpasses that of the straight shaft plow. This is entirely an improvement in structure and mechanics.
The small and portable Quyuan plow painted by Zhao Si was only widely popularized during the Song Dynasty.
The popularization of the short curved shaft plow was largely due to the increasing development of the southern region.
The long curved shaft plow is more suitable for large-scale farming. When the area is large and the terrain is not complex, the farming efficiency of the large plow is better than that of the small plow.
The southern region, which generally has a small area and complex terrain, is more suitable for the use of short curved shaft plows.
From then on, even during the Ming and Qing Dynasties, the population further increased, the grain production center moved from north to south, and the per capita land continued to decrease. It became the norm for ordinary people to have several acres of cultivated land per capita, and the small and precise short curved shaft plow was more in line with social requirements.
However, the long curved shaft plow has never disappeared, because essentially everyone is a curved shaft plow, and there is no real innovation or change in different sizes. It is just that most of the people who use the long curved shaft plow are the landlord gentry class, not the poor peasant class.
And during the Qin Dynasty.
Most of the land granted to a single farmer is about a hundred acres, and the production centers are concentrated in areas with stable terrain and uncomplicated landforms such as the Central Plains. Therefore, the long curved shaft plow is more suitable for promotion and use than the short curved shaft plow.
There was a military craftsman who solved the problem, so Zhao Si didn't need to use his brain to think. Wang Li ordered on the spot to make another long curved shaft plow.
The sun was at its peak, and it was time for lunch.
Unfortunately, Zhao Si was in a military camp, and the food ration was two meals a day. He was not very hungry, but he always felt a little uncomfortable without eating something at noon.
Taking advantage of the gap, Wang Li and Zhao Si continued to chat.
Zhao Si was happy to make good friends with each other, and thanks to Zhao Si's golden finger, the conversation between Wang Li and Zhao Si was also very pleasant.
Zhao Si saw that the conversation was almost over and he also asked the other party's name.
"My name is Wang Li." Wang Li said.
Zhao Si was stunned for a moment, feeling that the name was a bit familiar. He was thinking about the names of kings during the Qin Dynasty, and suddenly thought of Wang Jian, one of the four famous generals of the Warring States Period.
Zhao Si suddenly remembered it.
Isn't this Wang Jian's grandson? Thanks to reading a few historical novels in his previous life, Zhao Si still has some impression of Wang Li.
In fact, Zhao Si's history is very poor, and the channels for understanding history are limited to novel websites other than compulsory education.
"But Chehouzhi..." Zhao Si asked.
"It's the eldest father!" Wang Li seemed to be used to other people's inquiries, and the introduction was very familiar.
"Disrespect, disrespect!" Zhao Si handed over his hand.
He didn't know much about Wang Li, he had only seen it in novels. Most of his appearances in novels were in the background...
In my impression, Wang Li didn't have many deeds. He seemed to have taken over the Longxi army after the chaos? In the end he was defeated and disappeared.
Compared with the grandfather of the four famous generals of the Warring States Period and Wang Ben, who was famous and had many meritorious deeds, Wang Li can be said to be a typical representative of a tiger father and a dog son.
If it weren't for the fact that Wang Li had a grandfather who was the God of War, Zhao Si really wouldn't know him.
Facing Zhao Si's admiration, Wang Li just waved his hand: "Don't talk about this, didn't you just say that there are mermaids in the sea?"
Zhao Si smiled and continued to tell the story of the mermaid, without asking too much about the other party's family or being servile.
His astonishment towards Wang Li was more of a shock towards the historical figure.
Suddenly two thousand years have passed, and the characters who were once in the book are actually in the same time and space as myself, which is really exciting.
