Walk-behind tractors are a luxury elsewhere, but they are not a luxury and a rarity here in Liu Ponu.

Dozens of old farmers are pushing trucks full of fertilizer through the fields, and when they arrive at the field, they start to spread the fertilizer evenly on the ground with manure forks.

On the other side, five tractors are in charge of their own different areas.

Now the mechanization is still relatively simple, just a car head instead of the ploughing ox, the back is still used in the curved plow.

Therefore, the whole operation process needs two people to cooperate, but even if it requires two people, compared to before, farming is as easy as shopping.

The people in front only need to control the direction on the line, and the people in the back need to hold the curved plow, press the curved plow in the ground with a little force, at the beginning of the inexperienced, and later added two wooden strips for dragging on the curved plow, and put a horizontal plate in the middle.

The end of the strip has a piece of log that acts as a wheel, and when the depth is reached, the wheel rolls on the ground.

This seemingly useless device actually made the people who came after it a lot of power.

At the beginning, people need to press down hard, when the wheels touch the ground, the people behind them stand directly on the transverse plate, with their own weight to ensure the depth of the coulter into the ground, two small wheels to ensure the verticality of the plough body, even if occasionally crooked, people can also adjust at any time.

In just one morning's effort, a tractor turned over more than 20 acres of cultivated land, which is absolutely efficient.

This also means that a tractor can turn over almost 40 to 50 acres of land a day, and if you strictly abide by the law of sunrise and daily income, you can at least ensure that the number of acres of land is more than 50 acres a day.

"Brother Nu, this tractor ploughing is really an eye-opener for us, just such a one, two people, one day's work can do the work that the family used to do in a month, and it is even more beautiful." Although it is not the first time that the little mule has seen a tractor at work, every time he sees it, he will be deeply shocked by this shocking scene.

"The efficiency is still too low...... although Liu Ponu also knows that he is invincible now, but many things can't stand the calculation at all.

"Is this still low?" The little mule scratched his head in confusion, I don't know what kind of efficiency is efficient in Liu Ponu's heart?

Spring ploughing is different from autumn ploughing, spring ploughing is basically not short of water, and the air contains more water than autumn.

Therefore, spring ploughing can increase the time of ploughing to one month, although the earlier ploughing will still have a certain impact on the cultivated land, but in order to be able to grow a few acres of land, this effect is acceptable.

However, autumn ploughing is different, the temperature during the day is still a little high, and the land that has been turned over will be completely dry in two days, and the land has been dried before the time of sowing, which will affect the germination of seeds.

Therefore, although autumn ploughing can be cultivated for one more season, the control of cultivation time is more strict.

In other words, the best way to achieve the effect is to complete the work of ploughing, leveling, dividing the ditch, and cultivating within three to five days before sowing.

The longer it drags on, the worse the effect will be, of course, proper watering will help, but this amount is not easy to control.

If this efficiency is followed, a tractor can only dry two or three hundred acres of land at most in an autumn plowing period.

Well, with this efficiency, Liu Ponu can only meet the demand by ensuring that every two households are equipped with a tractor, and he has to work very nervously, even at night, he has to work overtime for a while.

"Get another curved plow and hang it on the tractor and try it out to see if you can drive two new plows!" Liu Ponu immediately arranged.

This matter is not in a hurry, because he is experimenting here, and if he wants to comprehensively promote winter wheat, then Liu Ponu must conduct experiments here for at least three consecutive years, or even longer, to ensure that it is correct before it can be promoted.

After all, agriculture is a very important matter, if Liu Ponu can't come up with convincing evidence, even if he can get the imperial court to force it, he will never dare to try it easily when it comes to the people.

But we must find a solution as soon as possible, the current big man can't make so many tractors.

Soon, the two curved plows were hung behind the tractor, the speed of the tractor was significantly reduced, and the sound was a little more dull, and it was obvious that it was much more difficult than before.

After an afternoon of testing, it was found that the efficiency had indeed improved, with a single unit turning less than 30 acres in the afternoon, while dragging a double unit turned about 35 acres.

But the bad news is not without it, the workshop inspected the tractor that night, and it turned out that the tractor dragging the two units was badly worn, and if it continued to do so, I am afraid that it would not be long before it would be lying on its stomach.

"The First Evolution"

Of course, there is a solution, and that is to increase the horsepower of the tractor.

There are no problems at all in terms of technology, the tractors used to plough the land are the least horsepower, and the more powerful tractors they can build at any time.

But the problem is that the resources are insufficient, and now the resources are a big problem even to supply the large number of trucks needed by the army, not to mention the large steel companies such as flint guns, grenades, and shells.

Regarding this issue, Liu Ponu chose to give up for the time being.

There's nothing to hesitate, he still has a few years to verify this problem, Liu Ponu can also wait for the development of the steam engine, if you use the steam engine to turn the ground, there should be no problem at all with five or six coulters behind a trip, right?

When the time comes, it will be half an acre of land, and turning over thousands of acres of land a day is not like playing?

Flattening is simpler, there is no rotary tiller, then use the soil method to solve, put the ladder on the ground, install some iron nails at one end, load heavy objects on it, and the tractor can pull and run, which is much more efficient than turning the ground.

If you still feel that the efficiency is not enough, then pull it with a rope behind the plow, and turn it flat while turning, and the tractor will do the work of two trips after one trip, which is not beautiful?

"I give you a holiday to rest, you don't just wander around in Chang'an like other people, and you actually squat here to watch farming?" When Liu Che learned the news that Liu Ponu was squatting in the Zhuangzi outside the city and farming, he was instantly shocked.

I asked again and again what kind of operation is this?

Could it be that the ancestors told me that the spring ploughing was all wrong?

Or is this kid wrong with any tendons?

No one could figure out Liu Ponu's intentions, so after dealing with official business, Liu Che couldn't help the curiosity in his heart, and went directly to the city to be a curious melon-eating crowd.

Of course, he is not lacking in the characteristics that the people who eat melons should have.

"Besides, do you know how to farm? At this time, the seeds planted will be frozen to death, you are wasting food, you are now degraded, you will not know, right? Liu Che didn't give Liu Ponu a chance to explain, and immediately sarcastically said one after another.

Well, the feeling of scolding people is still as cool as ever, especially using Liu Ponu's original words to scold Liu Ponu.

That feeling, it's like you're going to heaven, you know?

"You bad old man just can't look down on people, you're jealous, you know?" Liu Ponu squinted at Liu Che and slammed back unceremoniously.

I haven't messed with the old man for a few months, if it weren't for the battle he started first, so that Liu Ponu almost forgot that he still had this skill.

"I'm jealous? I don't think anyone is good? Liu Cheqi's old face was flushed, and he rolled up his sleeves to talk to Liu Ponu, and said angrily: "I see that your kid is becoming more and more lawless, if you can't tell me one, two, or three today, do you think I will beat you up and can't take care of yourself?" ”

"Look, if you can't say it, just do it, a typical weak heart stress reaction......" Liu Ponu smiled and continued to provoke.

"Hey......" Liu Che's teeth were itchy with anger, and he was about to step forward and fight Liu Ponu alone.

But who is Liu Ponu?

How poisonous are Liu Ponu's eyes?

Can he give Liu Che this chance to do it with himself?

"Look, say you, you still don't believe in this evil, before I asked about agriculture in various places, Youzhou Thorn Shi mentioned in the report that some people in Youzhou will cultivate wheat before winter, and wait until it matures in the summer of the next year." Liu Ponu immediately looked ahead with a pretended face and said, as if he was not worried at all whether Liu Che would slam his sandbag-sized fist on himself, but in fact, he was panicked in his heart, for fear that Liu Che would not be able to control himself.

"Wheat? Something that dogs don't eat, and you're wasting your energy on it? I see that you are too idle, you have nothing to do......" Liu Che scolded with disdain.

"Little mule, go and get a steamed bun for Your Majesty......" Liu Ponu smiled and immediately ordered.

After a short time, the little mule took a fist-sized steamed bun from the frame, the color was a little dark, and it was slightly soft in his hand, which was a little soft compared to the steamed cake made of corn.

Fortunately, this steamed bun was made today, so Liu Che's old teeth were not removed.

Liu Che took the steamed bun suspiciously and looked at it for a long time, and then slowly put it in his mouth and tasted it, the entrance was slightly sweet, and it was also very smooth after importing, which was very different from the obvious graininess of corn imported.

"What is this stuff made of? I have never eaten ...... "Liu Che, who ate steamed buns for the first time, was very curious, the most important thing is that the taste is good and delicious.

Well, it's so fragrant, I'll definitely bring some back for everyone to taste later.

No, it's too cheap to take some away, this kid, even the ingredients and the cook, I have to pack them all and take them away, don't think about any less.

Seeing Liu Che's very satisfied appearance, Liu Ponu was completely relieved.

Although most of the people present have tasted this thing, and it also proves that this thing is actually very easy to digest, what is difficult to digest is just a layer of skin on the outside.

Liu Ponu grinds the wheat into flour with a stone mill, and uses a sieve to dry the skin of the wheat, even if there is a fish that slips through the net, it is still a very fine wheat husk, which does not have much impact on the digestive system at all.

Seeing that Liu Che was satisfied and curious, and his face was full of extremely serious curiosity, Liu Ponu said seriously: "This is made with the thing that the dog in your mouth doesn't eat......"

"What's that? See if I don't kill you rabbit cub who is neither big nor small......"
