Wei and Jin cooks

The first priority is to clear the blockage, and then we can talk about other management methods, but...

Looking at Zhao Hanzhang who was serious, Fu Chang said: "Actually, Wang Jing's method is very good. We can build another dike in this section and make double dikes to remove most of the sediment."

He said: "Since Wang Jing's time, and up to now for more than two hundred years, there have been no major floods in the Yellow River."

Zhao Hanzhang frowned, "Such a dam is too expensive and has no benefits."

"Benefit?" Fu Chang frowned and said, "Isn't it a benefit to be able to block the sediment and prevent floods in the Yellow River?"

"But the benefits are not equal to the effort," Zhao Hanzhang turned to look at Fu Tinghan: "What do you think?"

Fu Tinghan knew what she was thinking and said, "Do you want to build a dam that can store water, separate sand, and use water conservancy?"

Zhao Hanzhang: "Yes, here, in the last section of the canyon in the middle reaches of the Yellow River, the water flow here has a large drop, and there is a lot of water that can be used."

Fu Tinghan lowered his eyes and said: "It's too difficult, it can't be done in a day."

Zhao Hanzhang said: "Let's take our time."

"What is the top priority?" Fu Tinghan asked: "The only way is to dredge and dredge the road?"

"In the final analysis, the problem of the Yellow River is still a problem of sediment entering the river." Who has studied geography in junior high school or high school and doesn't know that this is the fundamental problem?

Zhao Hanzhang also read books of this type when she was in the library. She clicked on the drawings and said: "To fundamentally control it, we have to start from the banks of the Yellow River."

"It is very convenient for us to start now. Due to years of war and natural disasters, most of the villages near the riverbank on both sides of the Yellow River are empty. We can start planning from now on." Zhao Hanzhang said: "Calculate the safest and most suitable distance for work, and limit the distance between villages and The cultivated land is close to both sides of the Yellow River. In addition to the official tree planting, the imperial court will also allocate an additional amount of money for special funds to plant grass and trees on both sides of the Yellow River that can stabilize the soil and waterproof the land."

Fu Chang frowned and was thinking of how to remind her tactfully when he heard his eldest brother say slowly: "Sanniang, didn't you say that the treasury is empty? How can you still have money to plant trees? Not to mention whether the trees and grass can be consolidated. Water and soil can prevent sediment from entering the river, but how can you ensure that the money can be used effectively?”

Zhao Hanzhang: "Prince-in-law, I have a censor, a county guard, a county magistrate, and two mailboxes standing there. How can I hide from so many people whether there are grass and trees planted on both sides of the river bank? Besides, I also have eyes. I Will patrol."

"As for money," she blinked and smiled, "the special money does not have to come from the national treasury, it can also be money that does not go into the national treasury."

Everyone was stunned for a moment, puzzled, "No money going into the treasury?"

"Yes, the gifts, donations, or some of the labor they should pay can be exchanged for planting trees and grass."

Zhao Hanzhang decided to go back and discuss specific methods with Ji Yuan and others, such as how many trees to plant per household and how much tax and donations can be deducted from the lawn.

In addition, the land equalization system has been implemented smoothly. After this year's transition, the people should have settled down on the land. The new tax law should also be promulgated. Starting next year, the original land tax system of Jin Dynasty will be replaced by Rent Yong modulation.

It is also time for veterans and remnants of troops stationed in various places to be released one after another.

Zhao Hanzhang thought a lot for a moment, but he quickly broke away from his thoughts and continued to discuss water control. "Grass and trees can solidify soil and waterproof. This is true. If you don't believe me, ask Tinghan."

Fu Tinghan nodded, "We really need to plant more vegetation."

"But the sand on both sides of the Yellow River is soft and barren, so planting trees may not survive." Fu Chang was previously the magistrate of Heyin County and knows this very well. The soil on both sides of the Yellow River is very loose. As long as it rains, it will quickly gather into streams, directly Carrying sediment and rushing into the Yellow River.

This is how the Yellow River got so much silt. It is difficult to grow vegetation in this kind of soil. Maybe if they keep planting, the vegetation will be washed away after a rain soon.

Fu Tinghan said: "There will always be a way. In addition to planting vegetation, you can also try the method of flushing sand with water."

This is a water control method proposed by Pan Jixun, the minister of the Ministry of Industry in the Ming Dynasty. In the Qing Dynasty, Chen Huang improved it. The method of "confining water and flushing sand" has always changed, but the general outline has remained the same and has been used until modern times. It can be seen that Its effectiveness.

Different methods are used in different areas and adapted to local conditions, which can not only control river sand, but also save manpower and material resources.

This is the first time Fu Chang has heard of this method, "Water flushing sand method?"

"Yes," Fu Tinghan took the pen in his hand and smeared it on the paper. "This method is mainly aimed at the middle and lower reaches of the Yellow River. The Yellow River has accumulated sand over the years. There is an unknown amount of sand at the bottom of the river. We can't dig it all out, and we can't." Send manpower to dig."

We are not modern now. We have all kinds of machinery and all rely on manpower. Even in the dry season, there is a lot of water in the Yellow River. It is very dangerous for migrant workers to go down to dredge and dredge the river.

Therefore, they can use other methods to flush the sediment from the river bottom and reduce manpower losses.

Fu Tinghan: "Tighten the river channel and use the huge impact of the water flow to flush out the sediment deposited on the bottom of the river."

When Fu Chang heard this, he came closer with interest and asked, "Where are you rushing to?"

"Here," Fu Tinghan drew on the picture the near embankment that collects water and washes away sand. After thinking about it, he simply drew the remote embankment that prevents flooding and the grate embankment that is used to block water and attack sand.

Seeing this picture, Fu Tinghan didn't need to explain it. Fu Chang understood it at a glance. He stood up happily and walked around in circles, "What a good idea. I never thought of this method. The Yellow River overflowed and spread to Jizhou, Qingzhou and Youzhou in the north. In the southern part of the state, Nanbo reaches Yuzhou, Yanzhou and Xuzhou, but their terrains are different, and the methods used should also be changed."

"The areas around Yuzhou are all plains, so the dikes you mentioned should be built. But in the Xuzhou area, the terrain is different. You don't need to build dikes at all to contain water and wash away sand. It's much more labor-saving than building dikes." Fu Chang happily walked around and said to Fu Tinghan excitedly: "Tinghan, you look like your grandfather, you are the person who is most like your father, hahahaha..."

After Fu Chang finished laughing, he looked at Fu Xuan, who looked dull. He was not very happy, "Brother, aren't you happy that Ting Han is so promising?"

"I'm so happy," Fu Xuan said: "I knew he was going to be successful early on. After all, he silenced his father and the princess, but I couldn't."

Fu Chang: "..."

He ignored him, turned to look at Fu Tinghan with a smile, and said, "Tinghan, with your ability, you should control the water."

Fu Tinghan said: "Second uncle, I'm just talking on paper, not able to control floods."

This was because after the task of water control fell on his shoulders, he only remembered it after trying to recall relevant knowledge points in the dead of night, but it was really just talk on paper.

Fu Chang didn't think so. He said with a serious face: "Ting Han, don't belittle yourself. We in the Fu family can control water. Your third and fourth uncles didn't learn much from your grandfather. They are also better than the officials of the Ministry of Water. You'll be able to master the water control diagram after reading it a few times. Even your father, who has no ambition to make progress, can master it at a glance. And you are smarter than us and are more like your grandfather. How could you not?"

Fu Tinghan opened his mouth wide.

Fu Yong and Fu Hong on the side also opened their mouths. It was rare for them to see their serious father praise someone like this.

Fu Chang said gently: "You just haven't managed it before, so you think you are just talking on paper. But when you really get to the edge of the Yellow River, you will understand that you can manage it. You will definitely know it."

Even Zhao Hanzhang was convinced by him. He turned his head and looked at Fu Tinghan with bright eyes and said, "Go ahead and try it. I think what the second uncle said is very reasonable. Maybe you are really talented?"

Fu Tinghan opened his mouth, but couldn't say anything against it for a long time. What should I do? He seemed to be more confident and convinced.

See you tomorrow
