When the stadium came back, Yang Qiao was not idle, and returned to the Science and Technology City again.

"Boom, boom!"

As soon as I got off the train, I heard the roar of locomotives, and in the distance, more than a dozen quad bikes were speeding around the city, and followed by dust.

This, Yang Qiao knows, this is a test of this motorcycle, one is to test the use of this engine, and the other is to test the manufacturing technology of this frame.

The most hateful thing is that this outside, it's not a normal road, it's just to buy a circle of land, start, first let the motorcycle run here slowly, and then, repair some potholes, this becomes a dirt road, for this dirt road, can it be used to test this vehicle, originally, this motorcycle is researched, Yang Qiao's plan is, first, to recommend it to Li Er, for the military, well, military motorcycles, can be used for thousands of miles.

"Lang Jun, this dust is also too big, and it has all flown to the city."

Coming to the city wall, Yang Qiao stood with the city defense chief, looking at the dirt road outside and the dust on the dirt road.

"Yes, this can't be done, or else, you arrange a part of the migrant workers to plant trees on both sides of this road, this sapling, find the seedling research center inside to cultivate, don't worry, when the climate is right, you can move some big trees down from the mountain, it is best to cooperate with the tall and short, after the dust rises, let the canopy directly press down the dust."

"Lang Jun, is this effective?"

"Whether it's effective or not, at least this canopy can play a filtering role, but it won't work out in the first few years, the saplings are small, and when the saplings get bigger, it's different, don't you find that in the city, some of the dust is much smaller now, it's all pressed by the trees."

This science and technology city has also been built for many years, so the trees in it, basically the original trees, have been moved, and the existing one is moved, one is newly grown, and the original Yang Qiao's design is more reasonable, this tree, tall, short, with it, so, when the dust rises, first go through the dwarf, originally, the dust flies short at this time, and then after the high, well, the dust also begins to fly high, layer by layer, and when it goes out, It's like a strainer, which filters the dust almost, but the leaves are dusty, and after a rain, they are much fresher, and even a fixed time spray will also freshen the canopy.

This science and technology city, from the city wall, is a factory city, it is better to say that it is a green city, that is, a green city, well, except for some undeveloped places, in fact, those places are not yellow, but a little desolate, there are trees on it, and they are also sparse, and they are still waiting to be developed.

There are few trees, maybe there is a strong wind, it will be a disaster, and it will happen if the trees are broken or something, but if there are more trees, there will be no danger, what a strong wind at night, look at it the next day, well, the leaves have fallen to the ground, and as for the trees, not even a single branch has been blown off.

"It's really that good, why don't I visit it myself?"

"Shengshang, no, that place is a little remote, although it is said that it is very fast to go by train, but for the sake of the safety of the Sheng, it is better not to go, or, arrange a part of the painters to paint this scenery and let the Shengshang visit?"

"This is not needed, in this way, let the technical personnel of the Ministry of Industry go, technical personnel, this is the way to say, let them study the greening construction of this science and technology city, to see if it can be used in this Chang'an City, although, at this time there are a lot of trees in Chang'an City, but it's all done by each household themselves, too scattered, for the whole, it still doesn't play much role, this coal ash, it's too hateful, but at this time, none of us can live without this electricity, so, this coal ash, there is still to be there, But now that there is this new method, isn't it just to plant some trees, even if it is in the palace, it is a big deal to arrange more guards. ”

Well, Li Er is determined to start dealing with this coal ash.

However, why didn't Yang Qiao come up with that hydropower generation?

This, it's not that he doesn't take it out, he's still arguing with the talker, whether it's better to take it out, or not to take it out, take it out, it's naturally beneficial, there is a dam, there is electricity, this one dam can supply the electricity of the entire Chang'an City, well, Yang Qiao calculated with the talker, this is to build a dam in the nearby river, at least it can ensure the power supply of Chang'an City for more than ten years, but after more than ten years, with the development of this industry, the electricity will be insufficient again.

This is the benefit of electricity, but there is also the benefit of storing water, which can also solve the problem of water supply in case of drought.

However, there are also disadvantages, that is, downstream, eh, will not increase the degree of dryness, resulting in changes in this water, in short, this place is not a rainy place in the south.

There is also the dam, which will have an impact on the geology.

Therefore, Yang Qiao is still arguing that even his own electricity use does not use this clean water and electricity, but spends a lot of money to transform this chimney, this, Li Er also knows that he can't imitate it, it consumes too much money.

"Boy, why are you thinking so much?"

On this issue of water and electricity, the chatter also asked Yang Qiao.

"Well, I won't say too much about the big truth, but, using this simple coal ash to make people consider the problem of pollution control, it can be regarded as a merit, besides, this hydropower, I don't take it out, people can't study it, don't you find that the ten tractor factories, each has its own research and development center, in front, there are people who have contacted the Seventh Lady, to auction a technology there, it is said to be a ploughing technology, you have also studied, after the technology is used, it will make the tractor easy twenty, Then, the speed will increase by ten, you see, isn't this the power of example, people are not stupid, but they don't know how to make money, but it's not just to grow food, sell food, in fact, there is a better way to make money! ”

Well, not to mention that Li Er is going to put greening on the agenda, let's go back to this city wall.

"Lang Jun, look at that motorcycle, it's already very practical, why isn't it officially produced, but still experimenting?"

Looking at the motorcycles that came over again, as well as the dust in the sky, eh, including Yang Qiao, who was on the city wall at this time, and the city defense manager, he also had to bring an umbrella to cover the dust.

No way, who let this be a dirt road, and a dirt road that has not really been built.

"No, we have to continue to experiment, perhaps, the stone road over there will also be used."

Yang Qiao pointed to the side of the mountain in the distance, where it was, but it was rocky.

"Stone road?"

"Well, however, there, it needs to be renovated, but it can be renovated, that is, it is smoothed, and some uneven places can be repaired, but this stone, there will still be it, and the rider of this motorcycle must also be fully armed, so that even if he falls, it will not cause too much injury, and this motorcycle needs to be tested in various terrains, and only in this way will it be provided to the saint."

"Lang Jun, you are sure that the Holy Lord will use this kind of motorcycle, before, the car, the Holy Lord did not use it very much."

Cars, Li Er also used some, however, most of them were used in transportation, and there were some tractors, which were the affairs of the Ministry of War itself, and they were used in armed tractors, well, tractors with lethality, so this is the problem of the city defense chief, before, it was not used much, and this motorcycle, will it be used more?

"Naturally, this fuel is good, and, in all kinds of road conditions, this motorcycle can be on, and it can be used at high speed, but this steam car tractor can only run at low speed, in fact, it can also be on high speed, but it's not the same when it comes to high-speed driving, on a good road."

"Lang Jun!"

"Lang Jun!"

Soon, a group of managers went to the city, Yang Qiao came, they naturally have something, it's okay, they will come to see Yang Qiao, naturally there is something to do, you need to report to Yang Qiao, the motorcycle is responsible, and the outside construction is responsible, all need to be reported.
