First, the historical origin of Xiapu kelp
According to the records of Xiapu County, wild kelp is distributed on rocks 2-3 meters below the low tide line in Xiapu County. In the 1940s, farmers (fishermen) in coastal and island villages of Sansha Town began to harvest and breed sporadically, making Xiapu the earliest county in South China to collect and breed kelp. 1957, Xiapu County began to carry out experimental farming in San 'ao, Sansha Town and Dong 'an in the southwest. 1958 successfully cultivated 5 mu of kelp. In the same year, according to the "Instructions on Vigorously Developing Kelp Culture" issued by the Ministry of Fisheries, kelp culture was listed as the main project of the "Great Leap Forward". 1960 kelp nursery in eastern Fujian (hereinafter referred to as the nursery of Sansha Fishery Company) used natural light to carry out indoor kelp cultivation and seedling collection experiments. After the success of 196 10, autumn seedlings were supplied to kelp culture areas in batches. From 65438 to 0972, the county farm cooperated with the aquatic technology department to reform the material of kelp seedling rope, and replaced the traditional horse hay seedling rope with polyethylene rope wrapped with brown silk, which achieved obvious economic benefits and was commended by the Provincial Fisheries Bureau and popularized throughout the province. 1983, the county farm successfully used kelp floating frame to cultivate mussels. 1984, the summer kelp seedlings in the nursery room of Sansha Fishery Company successfully crossed the natural sea area, which improved the ability to provide high-yield and high-quality kelp production. After more than 50 years of continuous development, technological innovation and seed selection and cultivation, Xiapu kelp has formed its unique quality characteristics. Xiapu kelp production area was included in the "Sixth National Agricultural Standardization Demonstration Zone" by the National Standardization Committee.
Second, the quality and characteristics of Xiapu kelp
Its leaves are strip-shaped, unbranched and its plants are robust. Fresh kelp is olive brown and shiny, with a length of 1.5-2m and a thickness of 1-4mm. Affected by the unique lake-type marine ecological environment, the breeding cycle is shortened, the algae are fresh and tender, and the crude fiber content is low; The dried product is dark brown, tender, smooth and soft; The finished salty kelp is emerald green, easy to rot in cooking, sticky, smooth and refreshing, and mellow.
Xiapu kelp is rich in protein, amino acids, vitamin B 1, B2, carotene, iodine, calcium, iron, zinc and other trace elements. In dried kelp, protein is 10%, iodine is 0.3%, total amino acids are10/g/,calcium is 70 16mg/, iron is 382 mg/, and zinc is 8mg/, β. Microscopic; G/ 100g, vitamin B 2190&; Microscopic; G/ 100g. Xiapu kelp is a pure natural green pollution-free product, which does not contain fertilizers and drugs. Regular consumption is beneficial to realize the acid-base balance of human body and keep the body fluid slightly alkaline. It also has the functions of softening and resolving hard mass, eliminating phlegm and relieving asthma, diuresis and clearing away heat, reducing blood fat and blood pressure, accelerating cholesterol metabolism and reducing tumor risk.
Three. Xiapu kelp industry
Kelp is one of the main products of traditional agricultural economy in Xiapu County, with a long history and large scale, and the seaweed culture area available for development and utilization is more than 500,000 mu. 10 coastal towns and villages have carried out large-scale planting and breeding to varying degrees, and their area and output rank among the top in coastal counties (cities) in China. In 2008, the county planted and cultivated 62,600 mu of kelp, with an output of160,500 tons. There are more than 230 kelp processing plants, processing 44,000 tons of kelp products with a total output value of 963 million yuan. There are more than 10000 people engaged in kelp industry, and 15000 people directly benefit.
At present, there are more than 230 kelp processing plants in the county, and more than 5,000 salespeople travel north and south. There are sales outlets in Zhejiang, Jiangsu, Hubei, Hunan, Hebei, Henan, Sichuan, Chongqing, Heilongjiang, Jilin, Liaoning, Guangdong, Guizhou, Anhui, Jiangxi, Xinjiang, Shanxi and Shaanxi, and Xiapu kelp products are all over the country. With the continuous expansion of product sales, Xiapu kelp is widely praised for its high quality and specific quality.
Xiapu county further increased its support for kelp and laver industries, and proposed "implementing brand-driven strategy to accelerate the cultivation and development of kelp and laver industries in Xiapu". 20 13 won the titles of "hometown of kelp in China" and "hometown of laver in China" approved by the State Administration for Industry and Commerce. From May 265438, 2003 to May 2, 2003/KLOC-0 to May 22, 2003, China Aquatic Products Processing and Marketing Association organized an expert review team to conduct on-the-spot investigation on the kelp and laver breeding environment, breeding production, product processing, product quality and certification in Xiapu County, and strictly examined the relevant application materials. Xiapu county has outstanding advantages in kelp and laver breeding and processing industry, which plays a key role in promoting local agricultural economic development and increasing farmers' income.
