Where salt is produced in Ningxia, and which factories in Ningxia produce by product salt

There is no place in Ningxia where salt is produced, and the salt we eat is mainly from Qinghai. The production area of salt in China is very widely distributed, from the northeast to Hainan, Taiwan, from Xinjiang, Qinghai, Sichuan-Tibet to Inner Mongolia, producing a wide variety of salt: sea salt, well salt, rock salt.

pool salt, etc. Among them, Liaoning, Shandong, Lianghuai and Changlu salt farms are rich in sea salt, which is famous since ancient times. Well salt is most famous for the artesian wells in Zigong City, Sichuan, which has a history of more than 1,000 years, and rock salt is produced in Sichuan, Yunnan, Hubei, Hunan, Xinjiang, Qinghai and other places.

There are many saltwater lakes in Shaanxi, Shanxi, Gansu, Qinghai, Xinjiang, Inner Mongolia, Heilongjiang and other places, which are rich in pond salt, the largest of which is the Qaidam Basin.

The salt pond of Zar Khan.

According to statistics, the salt mined from this salt pond alone is enough for China's 1.2 billion people to eat for more than 4,000 years. Others, such as Qinghai Chaka Salt Pond, Gansu Jilantai Salt Pond, and Shanxi Jiechi Pond, are all famous pool salt producing areas.

The main producing areas in China are Qinghai, Inner Mongolia, Xinjiang, Shanxi and other provinces and regions in the northwest, accounting for about a little more than 17% of the total output of China's salt industry. In addition to sea salt, there are also well salt, mineral salt (rock salt), and lake salt.

Among them, sea salt is the main salt species of China's salt industry, accounting for more than 60% of the output of the entire salt industry, well salt accounts for about 30%, and lake salt accounts for about 10%.

Yanchi County. And Guyuan City also found a large salt mine...

Summary. Ningxia's main by-product salt is:1

Ningxia Zaoquan Salt: Excavated from Zaoquan Salt Field, white, non-toxic and harmless, with low heavy metal content, high mineral content, low nitrate content and antibiotics, it is the most distinctive edible salt in Ningxia. 2.

Ningxia Islamabad Salt: The earliest recorded discovery of the Islamabad salt pans dates back to the late 19th century and is one of the most distinctive industrial industries in the city of Islamabad, Ningxia, known for its high purity and rich mineral content. 3.

Ningxia Ziyang Salt: Ningxia Ziyang Salt Field is the largest salt field in Ningxia, with an area of 10,000 hectares and a salt layer thickness of up to 700 meters.

Excuse me, but please go into more detail?

Ningxia's main by-product salt is:1Ningxia Zaoquan Salt:

Served by Sun Xun from Zaoquan Salt Field, white, non-toxic and harmless, with low heavy metal content, high mineral content, low nitrate content and antibiotics, it is the most characteristic edible salt in Ningxia. 2.Ningxia Islamabad Salt:

The earliest recorded discoveries of the Islamic Salt Fields date back to the late 19th century and are one of the most distinctive industrial industries in the city of Islamabad, Ningxia, known for their high purity and rich mineral content. 3.Ningxia Ziyang is noisy salt:

Ningxia Ziyang Salt Field is the largest salt pan in Ningxia, with an area of 10,000 hectares and a salt layer thickness of up to 700 meters.

The soil in Ningxia is mostly silty, loose structure, strong permeability, moderate capillary pore diameter, groundwater through capillary rising speed is fast, rising height is large, and the critical depth of groundwater is trembling and boring, and the soil is prone to salinization. The critical depth of groundwater determines the speed of soil salt accumulation. The capillary water rise height and the reputation velocity of soil texture affect the critical depth of groundwater. Layers of soil texture and tillage.

Soil structure affects the critical depth of groundwater. With the change of groundwater level, the higher the capillary water rises in the high groundwater level, the more salt is brought to the surface, and the salinity accumulates after the water evaporates, and the higher the salinity of groundwater, the more serious the salt accumulation.

The soil in Ningxia is mostly silty, loose structure, strong permeability, moderate capillary pore diameter, groundwater rises quickly through capillary, high rise, and large critical depth of groundwater is easy to produce salinization. The critical depth of groundwater determines the speed of soil salt accumulation. The height and velocity of capillary water rise of soil texture affect the critical depth of groundwater. Layers of soil texture and tillage.

Soil structure affects the critical depth of groundwater. With the change of groundwater level, the higher the groundwater level is high, the more the water rises in the capillary bedrock pipe, the more salt is brought to the surface, and the higher the salinity of groundwater after evaporation, the more serious the salt accumulation degree is.

The saline-alkali land of Ningxia is chloride salt.

Saline-alkali land is a general term for various saline and alkaline soils and soils with different degrees of salinization and alkalinization. Saline-alkali land contains potassium, sodium, calcium, magnesium chloride, sulfate, bicarbonate and other saline-alkali components, with poor physical and chemical properties, resulting in the growth of most plants is inhibited to varying degrees. Soil salinization is one of the most serious environmental problems in the world, and the improvement and utilization of saline-alkali land is of great significance to the sustainable and healthy development of rural economy, land management, and ecological environmental protection in China, especially in the inland arid agricultural irrigation areas.

Ningxia Hui Autonomous Region is located in the eastern part of Northwest China, the middle and upper reaches of the Yellow River, in the middle temperate semi-arid and arid zone, with scarce precipitation (average annual precipitation of 292 mm), strong evapotranspiration (water surface evaporation of 1 296 mm), and the total local water resources are 111.7 billion m 3, accounting for only 0 104 %。In recent years, the problem of soil salinization in the Yellow River irrigation area has received great attention from the Ningxia Autonomous Region, and soil salinization has become one of the important problems affecting Ningxia's agricultural production, and the saline-alkali land in the northern part of Yinchuan has accounted for more than 49% of the total cultivated land area, which is in urgent need of transformation and control.

For a long time, extensive and in-depth research has been carried out on the improvement of saline-alkali land at home and abroad, and although certain achievements have been made, there are some difficulties that are difficult to overcome, such as the high cost of engineering, the treatment of symptoms but not the root cause, the loss of nutrients with water loss, and the lack of fresh water resources.
