Where is the main producing province of sea salt in China?

What are the famous sea salt producing areas in China?

(1) Luchang salt area

Luchang Yantian The salt fields with the largest sea salt production in China are mainly distributed along the Bohai Sea coast in Hebei and Tianjin, among which Tanggu Yantian is the largest, with an annual output of1190,000 tons. Luchang Yantian starts from Huanghua in the south and reaches Shanhaiguan in the north, including Tanggu, Hangu, Dagu, Nanbao, Daqing River and other Yantian, with a total length of 370 kilometers, totaling more than 2.3 million mu, with an annual output of more than 3 million tons of sea salt, accounting for a quarter of the total national sea salt output.

Yantian in Luchang Salt Area is mainly distributed in Laoting, Luannan, Tanghai, Hangu, Tanggu, Huanghua, Haixing and other counties. Its production scale (including salt field area, raw salt production capacity and salt industry output value, etc.). ) accounts for 25% ~ 35% of the national sea salt. 1988 crude salt output was 4 15000 tons, accounting for 50.2% of Bohai sea salt output. Judging from the development status of Luchang Salt Area, there is little room for expansion of Tianjin Binhai Tanggu and Hangu Salt Field. With the development of towns and port industries, there is still the possibility of further reduction, but Huanghua, Nanpu and Daqinghe saltworks still have considerable development potential.

(2) Ying Ge Haiyan Field

The largest sea salt field in Hainan Island is second to none in South China. Built in 1958, with a total area of 3,793 hectares, the annual production capacity is 250,000 tons and the highest annual output is 300,000 tons. The degree of mechanization is 69%. The main products are crude salt, sun-dried refined salt, sun-dried high-quality salt, powder-washed refined salt and so on. Among them, sun-dried high-quality salt 1988 won the title of high-quality product of the Ministry of Light Industry, and raw salt 1992 won the first prize of Rongai Salt Saving System. In the past two years, the management mechanism has been completely changed and the economy has been fully developed. We have invested and built an Australian factory with an annual output of 300 tons, a magnesium chloride workshop with an annual output of 300 tons, a spirulina factory with an annual output of 2,000 kilograms, and a natural carrot factory with an annual output of 500 kilograms. At the same time, the tertiary industry has been actively developed, and more than a dozen companies have been established, integrating industry, commerce, trade, tourism and real estate, which has opened up a broad road for the simultaneous development of diversified businesses in salt and chemical industry.

(3) Huai salt producing areas

It was named after the Huaihe River crossing Jiangsu saltworks. Jiangsu saltworks are distributed in the embroidered needle estuary at the junction of Sulu and Shandong in the north and the inclined long coastal zone at the Yangtze River estuary in the south, spanning Lianyungang, Yancheng, Huaiyin and Nantong 13 counties, covering an area of 653 square kilometers. Jiangsu coastal area is suitable for sea salt production, with the widest coastal beach in China and four totally different climatic conditions.

(4) Cixi Salt Field

One of the most important sea salt producing areas in Zhejiang Province, its salt-making history has exceeded 1300 years. The production of sea salt in Cixi ranks first in Zhejiang for a long time, and Anton, the main producing area, is known as the "Salt Capital of Zhejiang". Located in the south bank of Hangzhou Bay, it began in Tang Dynasty and reached a certain scale in Song Dynasty. In the seventh year of the Song Dynasty (1047), the people along the coast of Cixi built the first seawall, namely the Great gutang, and the saltworks moved to the north of the Great gutang. According to relevant historical records, there were three saltworks, namely Longtou, He Ming and Shiyan, successively built in Cixi in the Song Dynasty from east to west, among which the salt production of Shiyan and He Ming accounted for 64% of the seven main saltworks on the south bank of Qiantang River estuary, and its importance can be seen. In terms of the quality of salt, the salt produced in these two places is the first. "Song history. "Shihuozhi IV" said: "The sea water east of Shiyan is salty, so the salt on the bamboo slices is particularly white." Later, with the movement of the Qiantang River estuary and the siltation along the coast of Hangzhou Bay, many salt fields were abolished one after another. After13rd century, the sedimentation speed in the north of the Three North Peninsula accelerated, and the actual operation areas of Shiyan and Heming saltworks also moved northward, eventually forming Anton saltworks.

(5) Laizhou Bay Salt Area

This area is the main producing area of sea salt in Shandong Province, including 17 saltworks in Yantai, Weifang, Dongying, Huimin and other places, with a total area of about 400 square kilometers, and the sea salt output of 1988 was 2.939 million tons. From the level of technical equipment, product quality and economic benefits of enterprises, Laizhou Bay salt area is in a leading position among all salt areas in China. The comprehensive mechanization level of the main salt fields is over 60%, and the output per unit area is as high as 73 tons/hectare, ranking first in the northern sea salt area.
