Chapter 18 The Birth of the First Quyuanli!
The craftsmanship of military craftsmen is beyond doubt.

Several military craftsmen worked together, divided the labor and worked together, and it took about half a day to finish 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 to the curved shaft, and the big plow becomes a small plow.

The first Quyuanli was born in this era.

"Let's try it!" Wang Li was even more excited than Zhao Si, and urged the soldiers to experiment with farming cattle.

A piece of cultivated land directly next to the straight shaft plow was used for comparison.

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 oxen.

Under Wang Li's orders, a total of three old cows started to march with heavy steps.

Zhao Si and Wang Li followed behind and observed carefully.

The old cow walked around for a long time, Zhao Si silently followed behind 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 is not particularly large. In comparison, the Zhiyuan plow eats the soil deeper, but the depth fluctuates greatly. If you encounter a hard soil boundary, Or there are clusters of rhizomes, which are easier to float.

The quyuan plow eats slightly shallower soil, but the soil does not fluctuate much. Compared with the straight plow, it is obvious that the force is more balanced and the power transmission is more stable.

In terms of speed, the Quyuanli did not hit the Zhiyuanli, on the contrary, the Zhiyuanli was faster.

After plowing until the ground turned, Zhao Si looked back and found that the plow marks of the straight plow were also straighter.

When it comes to turning around, the light and curved shaft plow obviously saves more effort to turn around, while the long straight shaft plow requires a lot of effort, after all, the weight is placed here.

Going back and forth, objectively speaking, Qu Yuanli did not act like a slap to Chang Zhiyuanli, Zhao Si frowned.

Even Wang Li asked curiously, "I don't think Quyuanli is faster than Zhiyuanli."

Not only is it not as fast as Zhiyuanli, but it is more than a quarter slower.

Zhao Si was thinking about what went wrong, but found a group of military craftsmen approaching with joy.

The craftsmen of this era may not understand the so-called scientific principles, nor can they explain them.

But they are experienced old farmers and qualified craftsmen. Compared with Zhao Si, a modern person who has basically never farmed land, they keenly grasped the advantages of Quyuanli.

"That's a nice plow! That's a nice plow!"

Several craftsmen gathered in front of Quyuanli, carefully observing the difference between it and Zhiyuanli, and praising it at the same time.

"What's the good thing? It seems that the speed is not as good as Zhiyuanli?" Wang Li asked.

"General, this plow is small, and it only supports one person and one ox. Naturally, it is not as good as two oxen carrying a straight plow. It has just been plowed, and the plow marks on the ground are of the same depth. One ox carrying a plow is naturally not as fast as two oxen carrying a plow. It is also because the soil is not deep enough. Because the plow is too small, if it is bigger, it will eat deeper and faster than the straight plow.”

The military craftsman opened his mouth to explain, and Zhao Si suddenly became enlightened.

The Quyuanli made this time is only half the size of Zhiyuanli, because Zhao Si followed the memory in his mind.

Times are different from time to time.

During the Qin Dynasty, even the Zhiyuan plow was a luxury, and ordinary people still used the traditional farming operation mode of Leisi.

After the Han Dynasty, the long straight shaft plow gradually became popular.

It was not until the early Tang Dynasty that Chang Quyuanli was really released.

So far, the long straight shaft plow has been completely eliminated.

Under the condition of the same size, the performance of the curved shaft plow completely crushes the straight shaft plow, which is completely an improvement in structure and mechanics.

The small and portable Quyuanli painted by Zhao Si was not widely popularized until the Song Dynasty.

The promotion and popularization of the short curved plow is largely due to the increasing development of the southern region.

The long curved shaft plow is more suitable for large-scale cultivation. When the area is large and the terrain is not complicated, the cultivation efficiency of the large plow is better than that of the small plow.

However, the southern region, which is generally small in size and complex in terrain, is more suitable for using short curved shaft plows.

Afterwards and even during the Ming and Qing Dynasties, the population increased further, the grain production center transitioned from north to south, and the per capita land continued to decrease. The per capita arable land of ordinary people became the norm, and the small and refined short Quyuan plow was more in line with social requirements.

However, the long curved plow has never disappeared, because everyone is essentially a curved plow, and the difference in size does not really change the innovation. It is just that most of the people who use the long curved plow are the landlord gentry class, not the poor peasant class.

And the Qin Dynasty.

Most of the land granted to a self-cultivating farmer is about [-] mu, and the production center is also concentrated in the Central Plains, where the terrain is stable and the landform is not complicated. Therefore, the long curved plow is more suitable for popularization and use than the short curved plow.

A military craftsman answered the question, Zhao Si didn't have to think about it, Wang Li ordered another long Quyuanli to be made on the spot.

The sun was shining, and it was time for lunch.

It's a pity that Zhao Si is in the military camp, and the food ration is two meals a day. He is not very hungry, but he always feels a little uncomfortable if he doesn't eat something at noon.

Taking advantage of the gap, Wang Li and Zhao Si continued to chat.

Zhao Si was happy to make friends with each other, and thanks to Zhao Si's golden finger, Wang Li and Zhao Si's conversation experience was also very pleasant.

Seeing that the chatter was about the same, Zhao Si also asked for the other party's name.

"My name is Wang Li." Wang Li said.

Zhao Si was stunned for a moment, always felt that the name was a bit familiar, thinking about the names of the kings in the Qin Dynasty, and suddenly remembered Wang Jian, one of the four famous generals of the Warring States Period.

Zhao Si remembered it all at once.

Isn't this Wang Jian's grandson? Thanks to reading several historical novels in his previous life, Zhao Si still has a little 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 father!" Wang Li seemed to be used to such inquiries from others, and he was familiar with the introduction.

"Disrespect, disrespect!" Zhao Si cupped his hands.

He doesn't know much about Wang Li, he's only read about it in novels, and most of the novels show this guy as a background board...

In my impression, there are not many deeds of Wang Li. It seems that he took over the Longxi army after the world was in chaos?In the end, the defeat disappeared.

Compared with the grandfather of the four famous generals in the Warring States Period, and Wang Ben, who is famous and has made many achievements, Wang Li can be said to be a typical representative of the tiger father and dog son.

If it wasn't because Wang Li had a God of War grandfather, Zhao Si really didn't know him.

Facing Zhao Si's admiration, Wang Li just waved his hands: "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 to the historical figures.

Suddenly spanning 2000 years, the characters in the books are actually in the same time and space as me, which is really exciting.
