"In a building, there are three important things to look at: whether it is sited correctly, whether its foundation is laid correctly, and whether it is successfully constructed."
Yu Zai explained to Wen Ming and the leaders of the Shang tribe the characteristics of the swamp, what they currently wanted, and how to plan the plan.
Many factors such as geology and environment will affect the life of the building and the flow of breath within this range. It may even happen that a building changes the environment of a region. Although this situation is mostly positive in this era.
.
Clear the swamp, gain food +2, and use workers to improve this cell.
In the timeline of Yu Zai, Dayu spent thirteen years to govern the world. Among them, the people of the Shang tribe followed him, and the main area he governed was Meng Zhuze. So after governing according to his method, the floods of Mengzhu receded.
, Daze became a wetland. This wetland was vast and vast, with luxuriant water and grass. People "filled the silt with fertile soil, gathered together to cultivate it, built a few houses, and then formed tribes."
It was this governance that indirectly laid the foundation for Shang and Tang's conquest of Xia.
The swamp is a good place, and there are abundant peat resources underneath. Peat is the inferior coal mentioned in the Fire-Tired Country in the past. It is the primary stage of coal formation, and is referred to as "grass peat".
"Although it is important to protect the environment, and swamps are a more important part of it,..."
"Brother Zai, you are also protecting the environment. When the flood breaks out, everyone here goes to swim in the water. Come and protect us!"
Wen Ming was complaining on the side!
Brother Zai, you have to put people first. You are still protecting the environment these days. Nature is going to eat my mother alive!
Yu Zai put aside his emotions and began to tell everyone about some basic geological issues.
"To improve wetlands better, we must first understand what the wetland ecosystem is."
"The so-called ecosystem refers to a whole composed of all things and heaven and earth within a certain range. Within this whole, they have their own laws of life and will not be actively destroyed unless a third force interferes.
...Just like some animals can only live in wetlands, and some animals can only appear in forests, camels in the quicksand of the West will not appear in the swamps of the East. That's the reason."
"A swamp is a type of wetland..."
In the following time, Yu Zai first popularized the definitions of wetlands and swamps to everyone, so that they can understand the ecological structure inside. This is necessary, because according to the evolution of swamps, it can be divided into three stages.
After each stage of transformation, the work that can be performed is also different.
After all, real work is not like playing the "Civilization" series. Only one worker can complete the cell transformation. Real work requires the cooperation of many people.
Mengzhuze is a eutrophic swamp, which is the first stage of swamp evolution. It is the easiest to transform. In terms of stages, the swamp water at this stage comes from surface water flow, groundwater and rainwater. The main reason for accumulation is the land.
It is caused by low-lying areas, and the water supply source is mainly groundwater.
If it is a mesotrophic swamp or an oligotrophic swamp, there is basically no way to transform it, especially the latter. After the soil is heavily acidified, it can almost only be used as a mining area for fuel and chemical industries. However, these two technological points
, there is no way to point it out now, because the front-end technology is still gray.
These two swamp types are the middle and final stages of swamp evolution. At this time, the climate and environment in the area, including the land conditions, have been finalized. In the current era, unless hundreds of gods are found to help, ordinary people can only rely on
It is impossible for tribal people to have a huge impact on them in a short period of time.
Especially in this era of frequent floods, Meng Zhuze would only rely on the favor of the Yellow River and become more obese and unscrupulous.
"If Meng Zhuze uses it well, it can become an important reservoir for regulating floods. If it is not used well, it will become a shrew. In general, Meng Zhuze is still in the first stage of the evolution of the swamp. He is surrounded by
These eroded lands, after transformation, can become fertile and good farmland."
"So the first thing everyone has to do is to cut off the external water source, that is, the influx of water from the Daze, and the second is to dig drainage ditches."
Yu Zai issued the first work plan. During the period of spring plowing, the Shang tribe still mobilized a lot of manpower. Thanks to Yu Zai's plows and composting methods, and thanks to God, these two tribes in the Central Plains
There is basically a bumper harvest every year, and after the food is guaranteed, the requirements for hunting in the Central Plains are not very high, so a large number of idle manpower, including those wizards who perform sacrifices, are brought in to work.
There are more than 40,000 people in the Shang tribe. This number is very huge. One tribe can surpass the entire Yanshui tribe. Even the Chifang clan cannot compare with it in its heyday. Generally speaking, after the tribes in the Central Plains have a population of more than 10,000, their population reaches 10,000.
The maximum number is 40,000, which is the number of a medium tribe. If it exceeds 40,000, it is definitely a large tribe.
Most of the people in the Shang tribe were separated from the people of the Gaoxin clan. The Gaoxin clan has not been divided into people several times since ancient times, so it is normal for the population to be large.
Seeing more than 10,000 people working here, Yu Zai also trembled a little.
Damn it, people in the south only have more than 10,000 manpower to build a large flood control city. They still beg their grandfather and grandma to send recruitment advertisements everywhere to borrow talents to get so many manpower. As a result, the Shang tribe in the Central Plains is rich after all.
Dig some drainage ditches, and with just a few words, tens of thousands of people will come to help.
The gap is reflected here! In the south, five thousand people are considered to be the threshold of a large tribe. Most tribes only have a few hundred people, one or two thousand people. However, in the Central Plains, more than ten thousand people are nothing!
"The Central Plains are plains after all, and are naturally suitable for farming. Shennong has been expanding the soil for 800 years, and the productivity is much higher than that in the south."
Ten thousand people work here. When they heard that Yu Zai wanted to help them transform Daze, most of them were skeptical, but they did not dare to neglect the work at hand. After all, it was something agreed by the leader of their tribe.
In terms of spirit, they are quite different from the energetic people in the south.
After more than a month, everyone was covered in mud. Ruanzai divided the swamp land into areas, relying on the rolling hills, and sent people to cut off the water flow, that is, to artificially create them with boulders and soil.
A small embankment.
The basic length and width of the ditch have been dug out. Ren Zai also asked the people of the Shang tribe to prepare a lot of cut stones during this period. The soil in the swamp is soft and it is impossible to ram the soil. Just embed the stones around the mud ditch.
Prevent mud from backing up.
When the drainage ditch was first used, a large amount of water was poured out, and then people were allowed to plow the soil, and then used flames to cover a large area and evaporate some of the water vapor.
"Deep plowing of the land is also an important task to normalize the soil. Because the soil in the swamp is gathered together, it cannot breathe and seep water downward. Instead, groundwater continues to flow up to the ground in the opposite direction, so the water flow accumulates on the surface.
In areas where the siltation is too severe and sinks too deep, backfilling work needs to be carried out..."
"...along the criss-crossing ditches, they surge out in the opposite direction of Daze. The final destination of these water flows is a water flow called Zhuoshui. This water flow meanders all the way eastward and can be used as a large river.
