1. Porphyra capitata is more tender than ordinary Porphyra.
2. Porphyra capitata is brighter than ordinary Porphyra.
3. Porphyra is more delicious than ordinary laver.
The first growing and harvesting laver is called Toushui laver, followed by Ershui, Sanshui and Surabaya. Porphyra capitata is rich in many bioactive substances, such as polysaccharides, highly unsaturated fatty acids, taurine, carotenoids and steroid hormones. Porphyra has concentrated all kinds of B vitamins in laver, and it is harvested from1/kloc-0 to 65438+February every year, with the earliest batch at the end of 10.

Porphyra distribution
1, Porphyra species are distributed in cold regions, temperate regions, subtropical and tropical seas, but the subtropical to temperate seas are rich in species diversity. The geographical distribution of laver in China also follows this law, mainly distributed in the intertidal zone from the Yellow Sea and Bohai Sea to the southeast coast. In addition, a few species of laver are distributed in the coastal areas of Taiwan Province Province and Hainan Island, and their distribution has regional characteristics.
2. Porphyra species distributed naturally in the Yellow Sea and Bohai Sea are Porphyra yezoensis, Porphyra yezoensis and Porphyra hemiphylla, while Porphyra yezoensis, Porphyra rugosa and Porphyra yezoensis are mainly distributed in the southeast coast.
3. Porphyra rotundifolia is widely distributed in China's coastal areas, growing from south to north, and it is a wide-temperature variety. Based on natural groups and habitat environment, Porphyra yezoensis in the north of the Yangtze River and Porphyra haitanensis in the south of the Yangtze River have been formed in China.
4. Porphyra haitanensis is a kind of Porphyra haitanensis cultivated in warm temperate zone in China, and its output accounts for about 75% of the total output of Porphyra haitanensis in China. The cultivation areas are mainly distributed in the coastal areas of Fujian, Zhejiang and Guangdong. In recent years, with the rising price of Porphyra haitanensis and the improvement of culture technology, the culture scope has gradually moved northward to Nantong, Lianyungang and other places in Jiangsu.
5. Porphyra yezoensis culture is mainly concentrated in Jiangsu and Shandong, and its output and export account for more than 95% of the national Porphyra yezoensis industry.
