In the northwest of China, where does the water come from to irrigate the land?

Drawing groundwater resources for irrigation. When there is no other water source, or when other water sources are insufficient, machine wells are drilled at the edge of the field or in the field, and water is pumped for irrigation by power. This is simple and easy, but it increases investment in production.

There are many ways and means to divert water to the field, the most popular is to open ditches, build water diversion channels, lead the water to the hillside, and also dig grooves or open up bamboo joints on the tree strips, from high to low, one level at a time, one by one built on the mountainside to the modern economic society, the problem of terraced water source irrigation on the hillside is easy to solve, ** to the terraces buried cement pipe to divert water source irrigation, where there are reservoirs and rivers, ** also funded to build water towers on the terraces.

<> our ancestors in mountainous areas also used the local terrain to reclaim and create fields that are suitable for the local area, terraces. The most famous is in Yunnan Ailao.

The emergence of terraced fields solves the problem that the hilly area can also be planted, and it is generally believed that it is the Three Kingdoms Majun.

Perfected and improved and promoted. It is an irrigation machine that uses a sprocket drive to drive the scraper in the sink to turn over, so as to direct the water from the lower place to the higher place.

As a resource, water is protected by national laws, especially drinking water resources, which cannot be polluted, which is responsible for human health and all life. In the past, when there was water in the river, it was still more convenient to water, and the water pump was in the river, and the water could be pumped. At that time, a tractor was used for watering, and then it was slowly changed to electricity.

In rural areas, there used to be a lot of electric drains, and the pipelines of these electric drains generally led directly to the local rivers or creeks and reservoirs. However, the installation location of the electric row is all in the highest place of the terrace, and the reservoir is built in the area where there are many rice fields.

Using some of the current technology, water is stored in the rainy season and pumped to the field when needed. I remember digging about a dozen of them in a pond in our village to prevent drought. Most of the terraces are irrigated with a combination of natural rainwater and groundwater seeping out of the soil.

Some of the rainwater that falls from the sky goes directly to the fields to store water, and some of the rainwater falls to the ground on the top of the mountain and is absorbed by the forest vegetation.

Much of the land used for irrigation in northwestern China comes from wells, and some of it comes from the Yellow River.

All this water was brought from other places, and the rivers of other plains were brought in and watered. Because there is no water in the northwest.

Hello, Ningxia Plain is located in Ningxia, known as the south of the Yangtze River, leading to yellow irrigation. The Hetao Plain is located in the Inner Mongolia Autonomous Region, and is irrigated by the Yellow River. The Hexi Corridor is located in Gansu, at the foot of the Qilian Mountains, and is irrigated by alpine meltwater.

The Tu people describe the northwest region of China, the northwest region has scarce precipitation and an arid climate, and the main factors affecting the climate of this place are deep in the closed ear and fissed inland, far away from the sea, and the mountains block the humid air flow

Therefore, b
