Zhang Qianxiu looked at the map carefully and asked, "Mr. Shi, you don't have to tell me the advantages there, but the disadvantages there."

Shi Chengwang said: "this tens of thousands of mu of land, because it is located at the edge of the mountains, is directly embedded in the mountains. Although this is the edge of the mountains, the overall terrain is several meters higher than the plain."

"It happens that there are no big rivers in that area. I went there to investigate on the spot. The only stream of water comes down from the mountain. It's probably a small ditch. It's estimated that it can supply enough water for 10 or 20 households and irrigate dozens of mu of land. But compared with tens of thousands of mu of land, it's just a drop in the bucket."

"We have also considered groundwater. It's still because of the reason I just mentioned. In plain areas, there is a shallow groundwater source within three or five meters, and a deeper groundwater source of more than ten meters. However, we estimate that the groundwater source there is less than 20 meters, so it's difficult to exploit groundwater."

"There is another reason that is not suitable for exploitation, that is, excessive exploitation of groundwater at the edge of the mountain, which is easy to lead to the subsidence of the terrain. Although the subsidence of the terrain is not many, only a few centimeters or a few millimeters, such subsidence may lead to cracks in the mountain and cause landslides."

"It's like a concrete red brick house. If one side of the foundation sinks by one or two centimeters, and the other side doesn't sink, the wall in the middle will tear. However, if the house has beams, but the wall cracks, it's not a big problem, but it's hard to say about the mountain. If there's another rainstorm, there will be a big landslide."

Zhang Qianxiu listened to this for a long time, summed it up, and said: "Shi Lao, what you said is that there is no local water resources, and groundwater can not be exploited."

"Mr. Yuan told me from the very beginning that it would take about five kilometers to bring river water for irrigation."

Shi Chengwang pointed to a river on the map and said, "this river, with this piece of land, has a drop of more than ten meters. That is to say, the river is ten meters shorter than the ground. It's useless to build dams. The river bank is not so high. We can only pump water up."

Zhang Qianxiu frowned slightly. Nearly 100000 mu of land needs to be irrigated. It's not a small project to rely on pumps alone.

Shi Chengwang took a look at Zhang Qianxiu and said, "boss Zhang, actually there is another way to bring water from another place. We also agree, but it's a long distance. The straight line is more than 30 kilometers."

"It's more than sixty kilometers to this area."

"But it's the canyon that I've been walking all the time. I don't need to build it in many places. I just need to dig it. There are mountains on both sides. In the middle is the canyon, which is the natural river channel."

"It's just that some places are relatively wide and need to be built manually, and some places have gaps and need to build riverbanks."

"After the water is brought in, we can give you a place to build a reservoir."

"This location, as long as who leads it, is a natural reservoir, and a dam can be built."

Looking at Shi Chengwang's explanation, Zhang Qianxiu thought about the feasibility of this plan.

Su Yuwei, who had never opened her mouth, suddenly said, "Shi Lao, this water can't be put in the reservoir all the time. After all, the output of the reservoir is limited. The downstream must build a drainage channel, and finally it will flow into that river."

"Your plan just diverts a section of the river from the middle and supplies us. The end point can't be in the reservoir you said."

As soon as Su Yuwei opens her mouth, Zhang Qianxiu responds immediately.

Shi Chengwang's goal is this river!

As long as this river reaches this piece of wasteland, it must continue to dig down, and finally merge into the original river. The diversion that Zhang Qianxiu dug out can benefit all the places he passes through.

Shi Chengwang: they want to use their reconstruction to benefit the villages below.

Shi Chengwang said with a smile: "it's not difficult to build the river channel below. If we collect the land, the water will not flow very much. We don't need cement. We can dig it directly, and then use stones to build the river bank. Because the terrain of that piece of wasteland is relatively high, it's not difficult to dig the river channel. Along the way, it can benefit more than a dozen villages with water shortage, and about 20000 people, In addition, your 100000 Mu area can provide water for 200000 mu of cultivated land. The dozens of villages below are almost entirely dependent on groundwater, and there are no other water resources. "

"If this diversion can be built, it will be in the future."

Zhang Qianxiu finally understood that the government would not suffer losses. The place was used by you, and you provided the land. Finally, it was theirs. The canals you built could also help them improve the water supply of more than ten villages.

But it's not that there is no profit at all. There are nearly 100000 mu. The yield of wheat per mu is almost the same as that of rice, and it's basically a little lower. After drying in the sun, it's possible to produce 700 to 1000 Jin per mu. 1000 is high yield. As a whole, one mu is slightly more than 200 Jin of rice.

Even if 800 Jin per mu, 100000 mu can produce 40000 tons a year. Even if the profit of a ton is 30 to 50 yuan, the profit of that year will be 1.2 million to 1.5 million. Plus subsidies, about one million yuan a year can bring in more than two million yuan a year.

Of course, under normal circumstances, there may be losses or high yields, so the profits will be different.

Zhang Qianxiu asked, "Mr. Shi, have you ever made a budget? How much will it cost to build this river course? "

It's at least 70 or 80 kilometers long, and there's a reservoir.

The construction of river channel is mainly to excavate and build river embankment.

Shi Chengwang said: "about three million, plus the reservoir."

Zhang Qianxiu asked again, "if I contract this piece of land, how much subsidy will I get in the past year?"

Shi Chengwang said: "about 900000, that piece of wasteland does not have 100000 mu, but 85000 Mu must have, about 85000 to 95000 mu, the whole place has 100000 mu, but some places can not be used as arable land, we can give you a start to use those places, but we can only give subsidies according to the area of arable land."

"We can give subsidies for three years."

It's a very simple account. It costs three million yuan to repair the river. The official subsidy is more than two million yuan. If they want to repair the river by themselves, they can barely repair it.

But after they had repaired it, they had no money to invest in the improvement of the wasteland. When they handed it over to Zhang Qianxiu, they could not only repair the river course, but also improve that piece of wasteland.

More importantly, the construction of the river is a one-time investment, and the subsidy is paid by stages.

Over the past three years, the interest rate has reached several hundred thousand. If we calculate carefully, there is a big gap between them.

Zhang Qianxiu said, "Mr. Shi, I'm going to have a field trip."

"There's no problem with that." Shi Chengwang said: "what I told you is true, but there is no way to investigate in the mountains. It's snowy in winter and you can't get into the mountains."

Zhang Qianxiu naturally understood: "this understanding, let's examine the original river, wasteland, and the villages below."

Shi Chengwang nodded: "yes, we'll go tomorrow. I'll arrange the car. If it goes well, we'll be back tomorrow night."

"Good!" Zhang Qianxiu said: "that's specific. We'll talk about it after seeing the place."

The conversation was almost over. Shi Chengwang and others got up to leave. Zhang Qianxiu talked with yuan pengchi for a while. Yuan pengchi was very supportive. He felt that the place had certain economic value.

Zhang Qianxiu hesitated because the return cycle was too long and the rate of return was very high.

In the early stage, it will cost some money to build rivers and reservoirs, invest three million yuan, and rectify land. As for agricultural machinery, we will find a way to get it from the Soviet Union.

In this way, the overall investment is about $10 million to $20 million. Compared with the R & D investment, this is nothing.

In the next few years, the income should be 2-3 million yuan per year, and the capital can be recovered in about 10 years. If it is better, the capital can be recovered in six or seven years, and it will be profitable in about 10 years. On average, the annual rate of return should be about 15%.

The annual return rate of 15% is relatively high among enterprises. The annual profit of the world's four major grain merchants is only about 3%.

As for the kind of investment that makes a lot of profits, returns the capital every year, and makes profits several times in two years, it is common in small enterprises, but not in large companies.

Apple has always been regarded as a company with high profit margin by many people, but its net profit is actually 22%, and Xiaomi's net profit is only 7%.

In 2018, the profit margin of a company was 8%.

The average annual rate of return is more than 21%.

In fact, the annual income of 15% is not low, especially in agriculture and traditional manufacturing.

Apple and Xiaomi are all technology-based companies, and bashen is in the financial sector.

Science and technology, Internet, energy, finance and medicine are high profit industries. Agriculture and traditional manufacturing are all low profit industries. What Zhang Qianxiu is doing now is low profit industry, and he can't do high profit industry. At present, there is no such condition in China for Zhang Qianxiu to do it.

After chatting with yuan pengchi, yuan pengchi and his three students went back to rest.

Only Zhang Qianxiu and Su Yuwei were left in the room.

Su Yuwei seldom talks when Zhang Qianxiu talks about business, but she usually listens on the side. In fact, she knows Zhang Qianxiu's business very well.

Zhang Qianxiu asked, "daughter in law, do you think this can be done?"

Zhang Qianxiu actually had a general decision in his mind. As long as there was no big problem, he would do it! One of the biggest problems now is the situation in the mountains. There is no way to make sure. It's winter and the mountains have been closed by heavy snow.

He will ask Su Yuwei because he always thinks that Su Yuwei is smarter than himself. Many times, he is more farsighted than Su Yuwei. That's because he has the memory of the last life.

Without the memory of his last life, Zhang Qianxiu felt that he could not compare with Su Yuwei.

In the last life, Zhang Qianxiu did not "open up", but was an ordinary office worker, a company's grass-roots management, and did not make any great achievements.

Su Yuwei doesn't have any "plug-ins" in her life. Her achievements now are already very good. Zhang Qianxiu has little help for her, which is her own work.

Su Yuwei said: "there is no difficulty in digging a river in the plain. It's similar to what Shi Lao said, that is, digging a pit and then piling up the river bank with stones. The cost is not big."

"But it's a lot more complicated and difficult to dig a river in the mountains. It's winter, so we can't go in and investigate. I don't know if it's as easy as Shi Lao said."

"If the terrain in the mountain is too complex, even if we need to dig a tunnel, not to mention three million, ten million may not be enough."

"After all, it depends on whether Mr. Shi has deliberately concealed anything."

"But overall, I think we can try."
