The third set of models is what Zhao Xi pays the most attention to.
Soil and water conservation was recognized in later generations, but it is not easy for people of this era to understand its principles.
This set of models is not for the river, but for the surrounding environment of the river basin. The shape of the model made the officials a little confused.
This is not in the form of a river, and there are no dams or gates. On one side is a bare mound. It can be seen that it was recently built. The soil has been treated, as if it has been tamped, but it is not as solid as ordinary rammed earth.
.
On the other side, there seems to be an original mound of Jinmyeongchi Recreation Garden. The surrounding area has been dug away, leaving only a lonely mound with vegetation. After digging out the waste soil, it should be the bare mound.
There are two mounds in a group, both close to Jinming Pond. On the upwind side of the two mounds, two huge wooden barrels were specially built to store water... I don't understand...
"You elders and ministers, you can first feel whether the soil quality of the two mounds is the same and whether the hardness is close, and then conduct two experiments."
Wang Zhongzheng continues to serve as the commentator.
The ministers and workers didn't know why, but they still did it. The mounds that were already there and covered with vegetation seemed to be looser in terms of soil hardness than the newly rammed mounds.
The ground around the two mounds is paved with cement, but it is still smooth.
After the ministers and workers were in place...that is, leaving the side of the mound, Wang Zhongzheng once again directed the inner prison and opened the water bucket high on the mound.
The way the bucket is opened is different from the previous two models. It is opened bit by bit. The water in the bucket slowly begins to wash away the two mounds...
It’s unbelievable! Under the mounds with vegetation, you can hardly see any soil being washed away, while the bare mounds have traces of erosion just by looking at them, a bit like the ravines in Linfu and Huanqing area...
··
At this time, Wang Zhongzheng once again directed the internal supervisor to fill the bucket with water and clean the cement floor under the mound.
"The last test was for water erosion, this time it was tested for rainwater..."
As Wang Zhongzheng finished speaking, the inmates moved the bucket from the top of the mound directly to the top of the two mounds. Then, they removed the baffle at the bottom of the bucket... At this time
Only then did I discover that the bucket originally had two layers at the bottom, and the remaining layer was filled with dense holes.
It can be seen very clearly with the naked eye. As the rain... let's call it rain. As the rain drops, the mounds with vegetation have almost no changes. You can't even see water flowing down the mounds.
, the surrounding mounds with vegetation are still clean.
As for the bare mound, seeing the mound turned into scars by the rain, the clean and smooth mound was already unsightly and full of pits. As for those water droplets, except for a few seeping into the mound, most of them were again.
A tiny ravine shape is formed at a time, flowing slowly downward.
After a while, the entire mound was surrounded by water like a yellow mudflat, and then formed a small stream along the terrain...
"This is the Yellow River flood, and this is how the real Yellow River flood is formed."
It was also the first time for Zhao Xi to have such a real experience, and he was a little solemn.
"As the saying goes, you can try to imagine the work of seeing the subtle things. You can try to imagine that you can enlarge this model to infinite size and place it in the northwest that you have seen or imagined. When the water flows together to form a river, it is the Yellow River...
"
What Zhao Xi said is actually not rigorous. In order to effectively explain the role of soil and water conservation, it can only be like this.
No one doesn’t believe it, everyone sees it.
"Officials, is it possible that this is the basis for water control?"
"That's not the case, or not all of them, but for the Yellow River, if we want to completely control the floods in the Yellow River, the latter two must be organically combined."
"Actually, you can think about it in comparison. The country has more than just one big river, the Yellow River. For example, the Yangtze River, the Pearl River, etc., which river is like the Yellow River, wreaking havoc on the basin every few years?"
"What the upper reaches of the Yellow River is like, compared to what it is like in Qinzhou, all the officials who served in Huanqing have seen it. There is no vegetation, and there are no channels to discharge floods. So, sediment is swept down all the year round. Over time, the entire middle and lower reaches of the river bed have been
The sediment is piling up and getting higher and higher, and even the sediment that is cleared every year and the dams that are raised can’t keep up with the speed of sedimentation!”
"If we want to control water, especially the fundamental control of floods in the Yellow River, we must ultimately conserve water and soil and build various graded bucket gates for flood discharge and irrigation in the upper reaches."
"The Yellow River is full of dangers, but only one set of riches. This set is Xingqing Mansion in Xixia and Yinshan Pasture in Northern Liao Dynasty, and further down is the Dynasty..."
At today's so-called banquet, my ministers and ministers were not limited to the cabinet, but even some involved in politics were present. There were some things that Zhao Xi could not discuss in depth.
"Officials and veterans believe that the current plan is to start with a temporary approach. During the dry season this winter, the Ministry of Works will take the lead in concentrating water to attack sand, and use it on Gyeongxi Road, Gyeonggi Road, and Jingdong Road at the same time."
"In the official house, the weather is cold. My colleagues are old and it is not suitable to live outside for a long time. I think that this time I have finished my personal statement and leave the cabinet to discuss, so my colleagues can disperse!"
Fu Bi is becoming more and more understanding. Indeed, some of the following words should not be announced to the public.
······
"The official method and the method of radical cure are beyond the control of the Song Dynasty..."
Fu Bi still did not dare to speak out. Although he had guessed the official's intentions, he was not sure. When leaving the cabinet to discuss matters, Fu Bi said this.
"Indeed, to cure the Yellow River floods, we need to jointly manage the entire basin. Whether it is Xixia or Northern Liao, there is naturally no reason to accept the instructions of the imperial court. But what if they are all under the jurisdiction of the imperial court?"
"I have said before that the unification of the Nine Provinces is not necessarily the ambition of the king, nor is it the king's militarism. It is the need for the security and defense of a dynasty, just like the dynasty needs the barrier of the sixteen states of Yanyun."
"Similarly, there is another point, which is the need to control floods. As we all know, in ancient times, our ancestors devoted themselves to water control, and it was because of water control that we created a living space for our descendants."
Zhao Xi carefully explained the causes of the Yellow River floods and the solutions. He proposed that constricting the water to attack the sand was on the one hand and for another purpose. Zhao Xi felt that it was time for his ministers to be prepared: I am going to attack Xixia!
"Guan family, do you have the conditions?"
"The fourth year of the Military Service Law is about to come. The plan of the Privy Council and the Ministry of War to serve one million soldiers can basically be completed at present. Even if we can't recruit enough soldiers to stand and win the battle, the country should still have nearly half a million soldiers.
Available troops!”
"The official family, I think it needs to be postponed for two or three years..."
Wen Yanbo put forward his opinion very seriously.
"I believe that it is a safe policy for new recruits to spend two or three years going to the northwest border to experience it in turn."
