got Chengxin's rough plan, and the three of them didn't stay long.

Consciously went to the excavator to check the oil, and then the two drove two excavators, and one drove a pickup truck.

Finally, I took a bottle of boiling water that had been boiled at noon, and set off directly in the direction of the village, which is just three kilometers to the south.

How do you know if there are three kilometers? That's simple, just look at the odometer of the pickup truck.

Another is to look at the water pipeline.

Looking from the canyon towards the village, the dormitory is on the right side of the pipe.

So, the whole future ranch, right on the right side of the pipe.

As for the left side of the pipeline, when the ranch is on track, the farm will be developed over there.

In the future, the manure accumulated on this side of the farm can be used on the farm side.

In Chengxin's plan, a ranch will be established at each development point, and a farm more than ten times larger will be built on the side.

This saves a lot of fertilizer money and so on.

Of course, the area of pastures is certainly much smaller, and the entire rocky valley plain still occupies seventy or eighty percent of the area with agricultural cultivation.

Pastures can occupy 10 percent of the area.

Think about it, there are more than 15 million mu, and 10 percent is more than 1.5 million mu.

In the future, 20,000 acres of grassland like this side will be calculated as one cow on two acres of land, which is about 10,000 heads.

Can't be counted, can't be counted, if it really is counted like this, 1.5 million mu can't be turned into 70 pastures and raise more than 700,000 cattle?

Half of his meow's slaughter in a year, that year is close to 10 billion?

It's not a question of whether you can sell it if you raise so much, there are two or three million tons of beef imported in China every year, so the demand is very large.

There is another reason, and that is that eggs cannot be put in one basket.

Although the larger the scale, the lower the cost of farming.

However, if you directly build 100,000 acres of pasture and raise 40,000 or 50,000 beef cattle.

If there is a plague in the unlikely event that such a large farm, not to mention all of it, half or one-third of the dead will be a loss of hundreds of millions.

Therefore, Chengxin thinks that each ranch should be at least ten kilometers apart, and it is better to breed more than 10,000 heads in one place.

In this way, even if there is a plague, there is a distance to buffer.

At the same time, there will be fewer deaths because they are less concentrated.

Those who are engaged in breeding are afraid of the plague or something, and they will hang a large piece.

As the saying goes, if you have a family with hair, it doesn't count, this is the fear of a large-scale death from the plague.

Chengxin is not idle here, the excavator is a little problematic, but it is quite easy to learn to learn the tractor.

Behind the four Hercules buttocks, all dragged a pair of eighteen hydraulic flipping plows.

Nine ploughshares are used at a time, each with a width of five meters.

The maximum ploughing depth of this group of ploughshares can reach more than 80 centimeters.

The maximum cultivated land speed can reach more than 200 mu per hour.

However, Chengxin doesn't need such a big depth, and the loose soil of the entire future pasture is only about eleven centimeters.

Therefore, the depth of arable land required for the entire grassland is less than 15 centimeters.

The extra three or four centimeters, that is, Chengxin felt that the soft soil was too little, and decided to use the life of the ploughshare to forcibly plough a little deeper.

In this way, the soft soil is thicker, and the grass will grow in a good environment in the future.

Especially in the hot summer, the sun is scorching at about 40 degrees.

At most, eleven or twelve centimeters of soil, even if you soak the soil once a day, you can't dry it for a day, and the moisture in it will be gone.

It is possible to sprinkle water continuously in the summer, but the consequence of doing so is that too much water is used.

The maintenance cost of other pipelines will also increase significantly.

Even if you have the blessing of spiritual liquid, you can't sprinkle water every day, there is no water in the soil, and no plants want to live.

】

Two or three centimeters more is an extra layer of protection.

And if you plough three or four centimeters more every year, after a few years, the soft soil of the entire grassland will be twenty or thirty centimeters.

Not to mention growing food, at least until then, even if there is no spiritual liquid, there will not be much problem in the pasture.

The more time passes, the more soft soil is cultivated, and perhaps after more than a decade, the soft soil in these fields can reach a thickness of more than half a meter.

When the time comes, you can plant whatever you want, and maybe you will be able to plant fruit trees.

Chengxin watched Li Xianke on the side for a while, and they drove a tractor to reclaim wasteland, and after a long time, they also felt a little itchy.

When a tractor returned not far in front of Cheng Xin, he stretched out his hand and beckoned as he walked that way.

Zhang Qiang, who was driving a tractor and ploughing three or four back and forth, saw Chengxin beckoning not far in front, and thought that he was operating improperly, so he hurriedly turned off the fire, and then got out of the car to see the ploughshare group behind.

After looking around, I didn't find anything wrong.

Just at this time, Chengxin also came over.

"What's wrong Chengxin?"

Zhang Qiang asked.

"It's okay, I'm just looking bored on the side, and I'm going to give this big guy a try."

"This one cost me more than 1.3 million, and I haven't touched it yet."

！

！ Typical idle eggs hurt.

"Will you open it?" Zhang Qiang asked suspiciously, did he believe in Chengxin.

This is also the fact that when they practiced driving some time ago, Chengxin didn't go to play two.

“！

What's so difficult about breaking the tractor? You can show me around and tell me a few precautions. ”

Chengxin is still quite confident in himself, this tractor is not big or big, and the operation is not complicated at all.

The steering wheel has a power assist system, or continuously variable gear, and an automatic direction correction system, which is similar to him driving his own SUV.

"Uh, okay."

Zhang Qiang thought to himself, if you want to open it, I can still pick it up.

Without much talking, the two boarded the tractor cab.

The cab is quite large, and it doesn't look crowded when you stay outside for more people.

Chengxin sat in the main driver's seat, under the command of Zhang Qiang, clicked the start button, and the tractor engine roared, and the smoke rushed into the right front of the window. Immediately, a puff of black smoke also came out.

The tractor is diesel-powered, with a lot of torque, and a little fire is a puff of black smoke.

After the ignition is completed, the right hand hangs on the forward gear, and with a light throttle, the tractor slowly drives forward.

Chengxin's feet are getting harder and harder, and the speed of the tractor is getting faster and faster, and in just a few seconds, the speed is more than 20 kilometers per hour.

He just thought, why are they all coming so slowly, isn't it driving quite fast?

Before he could speak, Zhang Qiang spoke first.

"Slow down, slow down, Chengxin, close the throttle, drive slowly."

Listening to Zhang Qiang's hurried voice, Chengxin loosened the throttle a little and doubled the speed of the car.

"What's the matter, isn't this fast?"

Chengxin turned his head and asked.

"It's not a question of whether it's fast or not, look at this monitor more when you turn it on."

Zhang Qiang pointed to a small LCD monitor on the right side of the bridge.

Chengxin looked at the monitor that Zhang Qiang pointed to and saw that there were nine small green grids on it.

"This shows the operation of the ploughshare at the back?"

Chengxin is at least not stupid, looking at the green grid above, he knows that this is a thing to monitor whether the ploughshare behind it is operating normally.

"Well, if the ploughshares in the back come across a big rock or something hard, they'll automatically put it away, and the lattice here will turn red."

"When the time comes, you have to get out of the car to see if the ploughshare is in trouble, if you encounter a big stone, if there is no problem, come back and press this again, the ploughshare will automatically return to its position, and then continue to plow the land."

"And Master Li said that our land has not been developed yet, and there may be big stones hidden in a few years."

"Therefore, the speed of the vehicle should not be too fast, at most ten kilometers per hour, otherwise the ploughshare will plough the big stones, and the sensor will not have time to react, resulting in the ploughshare not being able to be retracted."

"When the time comes, a lighter one of the auxiliary ploughshares will be damaged, and a heavier one will cause the skeleton of the entire ploughshare group to be deformed."

"So, you see that none of our four tractors are moving fast, just because we are afraid of encountering big rocks."

"But on the plow side, if you plow later, you won't be afraid of stones, and there will be no problem driving at a speed of 30 kilometers at that time."

Listening to Zhang Qiang's words, Chengxin also understood why he couldn't drive fast.

Reducing the speed of the car within ten kilometers, Chengxin drove back and forth, feeling that it was so boring to drive slowly.

However, for the sake of face, after coming back, he asked Zhang Qiang to get out of the car, and he came for another hour, ploughing seventy or eighty acres of land, and then exchanged the car for Zhang Qiang.

By the way, if you brag or something in the future, is this considered idleness, ploughing dozens of acres of land in one go?

After getting out of the car, Chengxin returned to the dormitory, drove the remaining pickup truck, stepped on the accelerator, and prepared to go to Zhou Yong and their side to have a look.

Maybe you can learn how to operate an excavator, right?
