Chapter 1090： Irrigation system

The fiscal revenue of Yongxing for eighteen years is estimated to be 1.2 trillion yuan.

The total GDP is about 12 trillion yuan, and the per capita annual income is 15,000 yuan.

(The data in the previous article is a bit unreasonable. In the future, this benchmark data will prevail. The data is too complicated and I have collapsed. Don't be true.)

Of the 1.2 trillion yuan, 200 billion has been invested in agricultural construction.

Among them, the most important one is the construction of water conservancy projects.

The land that has not been reclaimed today is basically for one reason, far away from the water source.

Water is the source of everything, and even drought-tolerant plants need water.

Of the 200 billion, 150 billion was used to build water conservancy projects.

There are super large-scale projects for the South-to-North Water Diversion, as well as medium-sized projects, such as harnessing the Huai River.

But more is the construction of small canals, spread all over the country.

Nanxiong, a small basin in the mountains.

Theoretically, Nanxiong's arable land is about 1 million mu.

However, the area of ​​arable land in Nanxiong is only 400,000 mu, and the development level is less than half.

The reason for this situation is lack of water.

The lack of water for arable land does not mean that Nanxiong lacks water. The main reason is that the rainy and dry seasons are too clear.

During the rainy season, the heavy rain fell for a few months, and the water rushed to the Beijiang River, into the Pearl River, and finally into the sea.

In the dry season, there is no rain for several months.

It is actually very easy to solve this problem. There are several places in Nanxiong's jurisdiction that are suitable for building reservoirs.

Just build a few more reservoirs to stop all the water in the rainy season, and then open the gates to release the water in the dry season.

In this way, water for arable land is guaranteed, and electricity can be generated incidentally.

In March, construction of the Kongjiang Reservoir in northern Guangdong began.

Kongjiang Reservoir is a natural reservoir, but its water storage capacity is average.

As long as a sufficiently high dam is built, the storage capacity of the reservoir can be greatly improved.

Together with Kongjiang Reservoir, the city's irrigation canal was also started.

Establish a reasonable irrigation network to maximize the use of water resources.

After the establishment of this network, those lands that are not suitable for reclamation can also become fertile fields.

"I would rather die than be a Dahua official."

Guo Xian, the chief of Nanxiong, looked at the huge construction team and sighed.

In previous dynasties, how could the imperial court take care of Nanxiong's places where birds don't shit.

But now, even in such a place where birds don't shit, the court has invested a lot of money and launched such a large project.

Guo Xian estimated that after the completion of this project, Nanxiong's arable land area will at least double, and agricultural income will at least double.

Moreover, this can also drive other industries.

In short, during his tenure, Nanxiong's economy will undergo drastic changes, and this will definitely count him as a credit, and a promotion is also appropriate.

The imperial court solved the biggest trouble for him. He only needs to be responsible for the specific execution according to the order, so that he can get credit if he doesn't go wrong.

This kind of official sits too easily.

Small water conservancy projects like Nanxiong are also in full swing in other places in Dahua.

At the same time, some other types of irrigation projects are also underway.

For example, the construction of Karez in Tubo is rampant.

Many people know the Great Wall of China and the Beijing-Hangzhou Grand Canal, but they don't know what Kanerjing is.

But in fact, Kanerjing and those two projects were merged into the three major projects in ancient China.

Its scale, role, and significance cannot be underestimated.

Kanerjing is a special desert irrigation system, which is widespread in Turpan and Hami.

Kanerjing can use the **** of the hillside to cleverly guide the underground undercurrent to the ground for irrigation.

The Kanerjing does not require power, it can be drained naturally, has less evaporation, is simple to construct, and is easy to manage.

For Turpan and other regions, it is the most suitable irrigation facility.

Before this, people of all dynasties and generations would dig karez spontaneously, but this spontaneous behavior had the disadvantage of low efficiency.

This time, the Dahua court sent a professional guidance team to systematically plan nearly 10,000 karez, which will cover a wider area of ​​arable land, and the utilization rate of water resources will be higher.

According to calculations, after the completion of this project, the area of ​​arable land and grain output in the area will be greatly increased, and the per capita income will be directly increased by at least 50%.

Moreover, turning this area into a granary can also reduce some of Dahua's burden.

Prior to this, the grain output here could not keep up with the population growth rate, and it has always been necessary to transport grain from the Central Plains by rail.

After this area is built into a granary, this batch of expenses can be saved.

Hebei, a well-drilling team is working in the field.

They are drilling deep wells.

Hebei lacks water, but there is no shortage of groundwater.

It's just that the groundwater is so deep that people in the past could not use it.

This is not a problem for Dahua. Dahua’s strategy is to dig deep wells in this area and install pumps to solve the problem of water shortage in the area.

Drilling a well is always not an easy task. In the traditional way of digging a well, if you want to drill a deep well, the well head must be large. It is too small for people to work underground.

If the wellhead is too large, the engineering volume will be very large, and the cost will be huge, and the gain will not be worth the loss. At the same time, it will cause great damage to the surface, and it will also pose a greater safety hazard.

Moreover, this depth is also very limited, more than ten meters, breathing and lighting are all problems.

It’s great to be able to drill a well with a depth of five or six meters instead of an individual family in the countryside. There is no need to expect a deep well.

At this time, the power of the country is needed.

The Dahua court sent a professional team and brought professional well-drilling machinery.

This kind of well drilling machine allows people to dig the well without going down, and can drill the well very small. Damage to the surface can also be minimized.

When the well was drilled, the villagers came to watch.

I saw the twist-like drill bit go down, and after a roar, the drill bit rose up.

Those sunken parts were covered with mud, sand and gravel. With a light shake, those mud and gravel were thrown away, and the drill bit entered the well again. Repeatedly, deeper and deeper.

"Unbelievable, unbelievable, what kind of ghost is this, how can you dig up the mud?"

The old man in the village was puzzled.

"Good guy, look at the stretched length, it's at least seven or eight feet long, we don't have to worry about running out of water in the future when we are farming."

Those middle-aged laborers are very happy. They don't care how this stuff is used to drill wells. They only see that it can bring huge benefits to themselves and reduce the pressure of raising a family.

And those children stared at the well-drilling rig for several days.

Among them, there are many people who dream of becoming a drilling rig operator in the future.

Deep water wells have been dug out, cement ditches have been repaired, and a granary will be born again.
