How to "quench thirst" for farmers in the world's first irrigation country?

The lifeblood of a person is in the field, and the life pulse of the field is in the water

Human beings live in water, and civilization is prosperous due to water

When we stand in Dujiangyan irrigation district

Permaneous irrigation system

Nourishing 11.316 million acres of Liangtian

Created the legend of "Tianfu Grasson"

When we are in the Bronze Gorge Irrigation District

River channels with dense spider web

Irrigation more than 5 million acres of farmland

Leave the reputation of "plug the Jiangnan"

And when we look at the whole of China

This kind of project is not uncommon

As the world's first irrigation country

my country has an area of ​​more than 10,000 acres in China

More than 7,000 large and medium -sized irrigation districts

The area of ​​cultivated land irrigation is 1.037 billion mu

Flow for thousands of years, farmers

Farmland irrigation

It's changing this

Countries that have occurred in water and drought disaster since ancient times

Sichuan: The old drought area in "Tianfu Grasson"

More than 2200 years ago

It can be called "the originator of the world's water conservancy culture"

Dujiangyan Jianzheng

Shu Di has since become the hometown of fish and rice

"Water and drought are from people, don't know hunger

There is no shortage of the time, and the world is called the heavenly house "

However, the little known is

Even in the kingdom of Tianfu, which is fertile and fertile,

There is still a area where ten years of droughts--

Grand Drought District

Le Zhi County is located in this drought area

Because the Minjiang River and the Minjiang River flow from both sides

Lezhi County seems to be located in

Above the "fish's back", can't save the water

Long -term extreme lack of water in the territory

In order to fundamentally solve the problem of water resources shortage

The country has invested 8.078 billion yuan

In Dujiangyan Irrigation District

Building the first phase of the Water Supply for Bihe

The terrain of the dry area is complex

Nearly 200 engineers

More than 10,000 builders

Lotten for 7 years

Created a total of 156.18 kilometers long

"Artificial Tianhe"

Nearly 2.25 million people in Central Sichuan area

Since then, there is no water deficiency

Anhui: "Nagoto Jiegua" is the farmland "thirst quenching"

In June 2022, it has entered the flood season

The Hangzhou Hangzhou Irrigation District has no precipitation

A summer drought quietly arrived

Field

Many figures are busy

This is the water content of soil water content in the irrigation area

Data collection and summary reports on various places

At the same time, the monitoring room of major reservoirs in the irrigation area

It also continues to pay attention to the lowest water level of the reservoir

After data analysis

Aimed at this year's water shortage area

Irrigation districts have been carried out in time

Constantly

Reconstruction and upgrade of the Hangzhou Hangzhou Irrigation District

The main water source with 6 large reservoirs

Taking the top 3 canal as the hub

More than 1,200 small and medium reservoirs are connected in series

More than 60,000 types of canal buildings

More than 200,000 pond weir

A unique "long vine knot melon" type irrigation system

The entire irrigation network is like the human blood vessel system

Countless channels

It is the capillaries all over the irrigation area

Finally diversion to every farmland

淠 淠 淠 淠 淠 淠

It is a microcosm of China's promotion of farmland water conservancy construction

"Fourteenth Five -Year Plan" period

my country will also build 30 large -scale irrigation districts

Newly increased irrigation area of ​​more than 34 million acres

Improve irrigation area by nearly 100 million acres

Ningxia: The "water -saving account" is calculated at the ground

"Water passes from the door

It's wrong without flowing

When we were irrigated in the past

How to flow if you want to flow "

"This means that it flows more

Anyway, everyone has spread it? "

"Yep"

In Quzhou Village, Wuzhong City, Ningxia Hui Autonomous Region

Yang Zijian, Director of Water Conservancy Service Center

Calculate the villager Yang Zongren:

Precise measurement through professional instruments

Yang Zongren's cultivated land area is 4 acres

500 cubic meters per mu of irrigation water per mu

His total water index in one year is 2000 cubic meters

Over the past acres

Yang Zongren's average water fee of 70 yuan a year

After quantitative water

The annual water fee per mu is up to 50 yuan per year

Such water consumption

It can ensure the harvest, and save water costs

Yang Zongren saw benefits

Just agree

Start in 2021

my country starts the reform of water rights in Ningxia

Change the extensive irrigation method in the past

According to the total water consumption of the Yellow River allocated every year

Ningxia combines crops in various places

Standards such as soil characteristics, irrigation area and other standards

Distribute the amount of water according to the fixed index

It ensures both crops and avoid excess distribution and cause waste

Henan: "Cyber Black Technology" in the ground

The sky drone is equipped with a spectral camera flying

Underground large self -properly spray irrigation machine for irrigation

The spectrum camera flew on the cropland

You can know how much water to pour water and how much fertilizer should be applied

It's like a "general"

Automatically generate "combat plan"

The large -scale self -properly spray irrigation machine underground

It's like "Smart Soldier"

After receiving the "combat plan"

Smart operation throughout

Mediterrane

Smart irrigation system

Native

Today, more and more

High -tech means independently developed by China

In the vast fields

The future of wisdom of Chinese farmland irrigation

Quick a clear water

Runyi Liangtian

Hard -working and intelligent nation

Rush the power of the Huanghuang China

Ecological water treatment system

Help food bumper harvest
