Gu Heju and the other four stood beside them and looked seriously, but their faces were full of confusion.

Isn't this exactly the same as before?

In their opinion, Xu Chen was working together again during this busy period, and he was completely useless in his work. He was tied together with two curved wood, and his shape had almost no change.

Xu Chen didn't explain, touched the sweat from his forehead and threw down the stone axe and said, "Move in and try again!"

"Good!"

The four close-fitting tools quickly started to work together and carried the wooden plow into the field. Before Xu Chen could give him instructions, Gu Heju quickly put a rope on himself and turned into a manniu to prepare to plow the field.

Xu Chen was very pleased. Although both of them looked not very smart, they were still very proactive in their work. Many things only need to be reminded to remember.

Although the appearance and style of the processed wooden plow seem to have not changed at all, it has undergone significant changes in its inner world.

This time, the plow arm is more inclined downward, and the traction force will be more downward when pulled, which will form an inclined downward pressure on the plowshare, making the plow tip easier to get buried.

The plowshare has a larger incline and the tip of the plow is slightly protruding downward, so that it does not require too much force to press the plow arm, so the plowshare can easily turn the soil open.

Xu Chen held the wooden plow and started the second test, and plowed back and forth for dozens of meters.

The effect this time is indeed much better than the first time. As long as you hold the plow handle firmly and press the plow arm, the wooden plow is easier to eat into the soil and has a much smaller floating feeling. Unless you encounter large stones or thorny roots, you can easily plow a mud ditch about ten centimeters deep.

Xu Chen felt much more relaxed this time, but Gu Heju and the others obviously felt more difficult.

After several trips of plowing, Xu Chen stopped to watch the quality of the plowing, and carefully checked the status of the wooden plow, and found that there was still a big difference from the state he wanted to achieve, but he could barely accept it.

At least the test after the second improvement is almost the same as the quality of a wooden hoe and a stone hoe turning over the ground, but the hoe can be thrown for dozens of miles in speed.

It took dozens of meters of plowing in just a few trips, and it took less than ten minutes. If you use a hoe, it would take at least an hour.

Plow is a very important tool revolution after humans entered the agricultural civilization. Its emergence changed the situation of primitive slash-and-burn planting, began to develop towards intensive farming, and grain output began to increase significantly.

Because plows can plough and destroy grassroots and pests buried deep in the farmland, killing them by exposure to the cold winter or the scorching sun, greatly reducing the survival of weeds and pests and diseases, and ensuring that the fertility of the farmland can fully support crop growth.

The soil and climate of cultivation cannot be determined by humans, but the quality of grain and farming can continue to develop and improve.

Moreover, the emergence of new production tools will inevitably speed up the quality and speed of cultivation.

Although this wooden plow is far from the state Xu Chen wants, it has begun to show its power.

"Look, is it faster than a hoe?" Xu Chen asked Gu Heju with a smile.

"Yes!"

Gu Heju nodded vigorously together, and at the same time he suddenly realized.

It turned out that this strange thing that Xu Chen had worked hard for several days was used to dig fields.

Although they had no idea what had changed Xu Chen's seemingly useless behavior just now, the quality of the tillage in front of them was indeed much better than the first time, and it was even more difficult to pull it up.

"You can change people and try to plow the palm of the Gulai."

As a wise man and innovative leader of the tribe, Xu Chen felt that after completing his preaching, he could start to be lazy again.

After the replacement, Xu Chen followed the side carefully to show how to hold the plow handle, how to press the plow arm, how to prevent the plowshare from moving, and how to shake the wooden plow when there is too much resistance so that the plowshare can smoothly avoid obstacles such as stones and tree roots, etc.

Although he had only had two brief farming experiences, he had never eaten pork and had seen pigs running. His past experience and some experience accumulated briefly still had some experience.

Under his guidance and teaching, Gu Lai returned to and flew back and forth several times, and gradually began to master some skills. Soon the quality of the plowing field also improved considerably.

Xu Chen and his friends were busy here, and more people were busy clearing debris and digging drainage ditches in the newly reclaimed farmland. They watched them get something strange and run back and forth in the fields, and then chew around the fields. They didn't know what they were doing. When they were resting, someone was curious and ran over to see them, and they shouted as if they had discovered a new continent.

The magic of this thing is completely beyond their imagination.

The three people can quickly and easily dig the soil with more than ten people using hoes together.

So amid the exclamation, more and more people were watching, and even Mother Ba and Ah Mother were attracted.

Xu Chen naturally took the opportunity to explain to them the benefits of doing this, that is, he could plow out the weeds and pests in the soil, and also used a wooden hoe to break up the plowed soil back and forth, and easily clean up all the grassroots and stones inside.

"Soga!"

Seeing Xu Chen's demonstration, everyone understood the benefits of coming here.

The wildfire cannot be burned, and the spring breeze will grow again.

Although these primitive savages do not understand the beauty and romance of poetry, they have the simplest and simplest life experience and have the most obvious understanding of the growth and breeding of animals and plants.

Wild grasses can not only reproduce through seeds, but grassroots are the fundamental reason for their prosperity.

When I farmed for the first time last year, everyone saw the madness of weeds. Even though the whole clan mobilized the weeds several times, the weeds in the farmland continued to rise terrifyingly, squeezing a lot of space.

There are many weeds in farmland because of grassroots.

If the grassroots can be cleaned up in large quantities, then the weeds in the farmland will be much less next year, and the oats and wild beans planted will grow more and better.

Therefore, Mother Ba and A-mu excitedly pulled Xu Chen and Guguqi gestured, saying that this thing is useful and you must make more.

Xu Chen naturally knew that plow was a good thing, but unfortunately, he prepared too late this year, and had no experience, and there was not much time. It was too late now, so he could only do his best.

There is still half a month left before spring sowing. In the past two days, some people are mobilized to go up the mountain to find suitable bends. It is okay to work hard to make a few. As for large-scale use, we will definitely have to wait until next year.

In addition, if the fields plowed with plows are not properly processed, a large number of grass roots will still not be removed, and some more suitable rakes are needed.

Therefore, Xu Chen left the wooden plow and asked Gu to continue to plow the fields with a few men who were eager to try. He arranged to take a few men up the mountain to continue looking for suitable bend wood. He went home to direct the two Wu tribe boys and tool men to continue to make wooden plows with the remaining wood.

With the experience accumulated from the first wooden plow that was barely used together, the rest can be made just by copying it.

The details are not detailed. Anyway, it is all newly cut wet wood, so it is enough to use it. After using this season, you can use it as firewood. Next year, you can find suitable wood stocks in advance to dry and then set aside. Make it slowly in autumn and winter, and it should be enough in winter and spring.

The division of labor is clear at present. Gu is responsible for teaching people to plow the fields, and the raising and leading people to cut appropriate wood. The tool man is responsible for making it according to his instructions. Xu Chen's main task is to complete another tool, which is rake.

Rakes are relatively simpler than plows, so they are faster to make.

Depending on the size and function, the shape and size of the rake are different.

The simplest one is naturally a rake, the one with a long handle. The nine-toothed rake of Marshal Tianpeng's immortal weapon is similar. It is convenient and quick to pull soil and weed, but it is only suitable for small-scale work. Rakes like rake fields must be very good.

At present, the area of ​​hundreds of acres of land is not bad, but it can only be relied on people, so it can only be supplemented. What Xu Chen wants to do is a large farm tool rake.

Either don't do it or it's in place at once.

But now the processing tool is stretched, which makes him feel a little powerful and unable to use it. It is like having enough money to go to the brothel. It turns out that it is all customers, and the young ladies come together to not accept customers.

There is enough wood for building a house. Choose two suitable woods with a thickness of calves, cut them into two long materials that are one meter five meters long, and then cut out two short materials that are two feet long. Then cut out the rough notched tenons and splice them together, and then tie the joint parts of the tenons tightly with hemp rope, so that a rectangular wooden frame can be obtained.

Cut out the two long materials of the wooden frame with an axe and then cut out the vertical grooves twenty centimeters apart. Use wooden sticks as thick as eggs to cut into short sticks half a foot long. After sharpening one end, tie them one by one with hemp rope in the grooves of the wooden frame.

After tying it up, what you get is a large wooden rake with wooden teeth on the front and back, tied with long ropes and put on animal skin straps, and such a simple and rough large field rake is ready.

Let the two teenagers carry them to the test field.

Half a day passed, and under the guidance of Gu, several men had plowed nearly two acres of land.

The area is quite large, but the effect is a bit terrible.

First, the wooden plow still has defects and does not have sharp plowshares, so the soil plowed is not neat and the depth is also inconsistent, and even more than one foot of the two furrows are separated by each other.

It is better to say that it is digging a furrow than plowing the land.

But Xu Chen could not ask for more. The sowing area was too large, so he could not do everything himself, nor could he ask this group of savages who had not yet fully civilized to do their best to cultivate carefully.

In fact, he was already satisfied to learn to use this thing.
Chapter completed!
