Jiang Hexing turned around and said, "Heng Tan, you should introduce Jia Rang's middle and lower strategies." Pen Fun Pavilion www.biquge.info"

Heng Tan nodded and told Jia Rang's middle strategy first.

Jia Rang's suggestion was to dig more canals in the Jizhou area, so that the people could use them to irrigate their farmland and share the urgency of the water flow, if not the best way, but it was also a trick to save the way from failure.

People may say: "The water level of the Yellow River is higher than the flat land, and the embankment is increased every year, but if it still bursts, no more canals can be opened." ”

Jia Rang once inspected the place eighteen miles west of the Shading Pavilion, and when the Qishui River entered the estuary, there was a golden embankment, which was one zhang high. From now on to the east, the terrain is getting lower, the embankment is getting higher, to the shelter pavilion, four or five zhang high. Six or seven years ago, when Jia Rang investigated, the Yellow River was so large that it increased to one foot and seven feet, destroying the city gate south of Liyang, and the water flowed down the embankment. The water had not yet crossed more than two feet below the embankment, and when I looked north from the embankment, I saw that the Yellow River was higher than the houses, and the people had run to the mountains. The water stayed for thirteen days, and the embankment collapsed and the government and people blocked it.

Jia Rang walked upstream along the embankment, inspected the water potential, and traveled more than 70 miles to the south, reaching Qikou, where the water was only half of the embankment, estimated to be about five feet above the ground. Now it is possible to build a stone embankment from the east of Qikou and open more sluices. In the early first year, the shelter pavilion was lower than the Yellow River, dozens of steps away from the embankment, and it was more than 40 years when Jia Rang surveyed before reaching the foot of the embankment. From this, the place is solid.

I am afraid that those who discuss it will suspect that the Yellow River is a large river that is difficult to subdue, and the Cao Canal in Rongyang is enough to prove that this sluice gate is only made of wood and earth, and it must be safe to build a stone embankment on a solid foundation. All the canals in Jizhou rely on this water gate. The ditch is not dug up, only an embankment is built in the east, which travels more than 300 miles to the north and flows into the Zhangshui, and its west side is often diverted separately because the foot of the mountain is a high ground; When there is a drought, the sluice gates in the eastern lowlands are opened to irrigate Jizhou, and when there is a flood, the sluices in the western highlands are opened to divert the water.

There are three advantages to opening water canals, and there are three disadvantages to not opening water canals. People are often exhausted by saving water and basically lose production; When the water is prevalent on the ground, the accumulated water evaporates, the people will get rheumatism, and the trees will soon wither, forming saline-alkali land without growing millet; The mouth of the river bursts and becomes food for fish and turtles: these are the three hazards.

If there is canal water for irrigation, then the salinity sinks, and the silt is filled to increase fertilizer; Therefore, planting wheat and japonica rice yielded five times higher than that of high-yield fields and ten times higher than that of low-yielding fields. Convenience in favor of the transport vessel: These are the three conveniences.

At present, there are several thousand officers and soldiers near the embankment of the Yellow River, and the cost of cutting grass and buying stones is tens of millions a year, which is enough to open the canal and build the sluice; In addition, when the people have received the benefits of irrigation, they will rush to open canals, and they will not get tired even if they are tired.

The people's farmland has been managed, and the embankment of the Yellow River has also been built, which is really rich and peaceful for the people, and can be maintained for hundreds of years, so it is called the middle policy.

Heng Tan talked for a long time, and drew some pictures, and Jiang Hexing understood a little. Jia Rang's method was to set up a sluice gate in front of the Golden Embankment, on higher ground. In addition, a sluice gate was set up downstream of the Golden Embankment to divert water from the Yellow River to Zhangshui in the north.

When the water is high, water is released from high places to relieve the pressure near the Golden Embankment. In times of drought, water is released from low-lying areas to relieve the drought in the north.

The construction of aqueducts has three advantages, fertile land, high grain yield, and convenient navigation. If the canal is not repaired, there are three harms, affecting production, the water disaster will form saline-alkali land, and people may be washed away by the flood.

However, this method is not a long-term solution, it can only work for a few hundred years, and it is not a cure.

Jiang Hexing asked, "Heng Tan, what about the next step?" ”

The next strategy is to repair the old embankment, fill in the low land, thicken the thin place, and the cost of labor is endless, and it has been harmed many times, which is the lowest strategy. This approach will probably work for a few years to decades.

After Heng Tan finished speaking, Jiang Hexing thought about it, the most prominent thing about this Jia Rang strategy was that he didn't trust the embankment, especially near the golden embankment. In his opinion, it is better to control the flow of water than to strengthen the embankment. Of course, the best thing is to give the water enough space, and if you don't control it, the harm will be even less. It's just that I don't know how this Wang Yi will make a trade-off and how to report to Wang Mang.

After Heng Tan finished speaking, Wang Yi waved his hand and asked everyone in the hall to retreat. There were only four people left in the hall: Jiang Hexing, Zhang Meng, Wang Yi and Heng Tan.

Wang Yi kept frowning, and it seemed that it was difficult to choose.

Jiang Hexing asked, "Da Sikong, what are you going to do?" ”

Wang Yi sighed and said: "Now the Yellow River is no longer a breach, but has been diverted. This project is different from the past, and it will inevitably rebuild the river. It is the choice of the river plan.

And Shun Hou, Wang Heng's method just now is somewhat the same as Jia Rang's strategy. They all advocate the Yellow River going northeast and into the sea. The method of closure and merger is to set up a flood discharge area in the area of Dongjun, and now in fact, there is still a flood discharge area, where people now estimate that the Yellow River has been flooded with flood discharge areas. In the future, it would be nice to set up a forbidden place here, or to have a large lake like Junozawa.

When the water is high, there is a place where the flood pours. It's much better that way. It's a pity that too many people are now surrounding lakes and cultivating fields, and they are always grabbing land with the water.

Hey, it's also difficult for the court, behind every piece of land is a family's rice bowl. Whoever smashes their job, everyone is anxious with you. ”

Jiang Hexing said: "Do you think the plan is better?" ”

Wang Yi said: "There are no good or bad plans, they are all good ideas, let's see if that one can be implemented?" Needless to say, the best must not be implemented at all, which is equivalent to empty. We also have to look at how much the imperial court's budget is, where the river will go in the future, and how many people will be moved. We will call this record to Your Majesty, and when the time comes, we will have to find some people who are in charge of money and grain, those who are in charge of rivers, and local Taishou to discuss together, so that we can come up with a real plan, it is still early. ”

Jiang Hexing understands that no matter what the plan is, it is only a few ideas, and there is still a long way to go before the plan can be implemented.

This meeting came here first, Wang Yi invited Jiang Hexing and Zhang Meng to a banquet, and no longer talked about the Yellow River during the banquet, and the two talked about various things about the Xiongnu, not to mention, Wang Yi was still really familiar with there. Heng Tan doesn't talk much, and the occasional words are all about asking Yangxiong.

It is said that now Yangxiong is in the barbarian mansion, dealing with the barbarians every day, Chang'an City is very prosperous, it seems that everyone is a generation, and now it is a pity to be reduced to dealing with these barbarians in Jianghexing.

When Zhang Meng heard this evaluation, he was extremely angry, Jiang Hexing didn't care, he listened to it and smiled, unwilling to get to the bottom of it. People who don't understand you, explanations are nothing necessary.

The banquet was very rich, Jiang Hexing and Zhang Meng drank a lot, and it was not until it was almost dark that they returned to the Barbarian Mansion. (To be continued.) )
