CATDOLL : CATDOLL: Is laver auricularia cultivated or grown? Laver is a plant that grows in seawater.

1. Is laver auricularia auricula planted or cultivated? Laver is a plant that grows in seawater.

Porphyra is algae, generally known as cultured.

Fungus is a fungus, generally known as cultivation or cultivation.

2. What are the main types of artificially cultivated seaweed?

The main artificially cultivated laver include laver yezoe, laver hainanensis, laver tangutica, etc.

1. Porphyra fronds mostly grow in intertidal zones, preferring sea areas with strong winds and waves, smooth tides, and rich nutrients. It is highly drought-resistant; the suitable light intensity is 5000-6000 lux, with the characteristics of high light saturation point and low light compensation point, and is a high-yield crop.

3. The adaptability to low temperature varies with the water content of the algae. When it is quickly dried to 20% water content, it can be put back into seawater after being refrigerated at a low temperature of about -20℃ for several months to 1 year. The adaptability to the specific gravity of seawater is wide, but 1.020-1.025 is appropriate. The filaments have poor dryness resistance and require low light, so they are naturally distributed below the low tide line. When the temperature begins to drop and there is seawater flow, the conchospores are often released in large quantities every morning from 9 to 11 o'clock, showing an obvious daily periodicity.

3. Porphyra is a general term for marine symbiotic algae. Rhodophyceae. The algae are membranous, called thallus. They are purple or brown-green in color. The shape varies with the species. Porphyra is a marine red algae. The thallus is composed of a layer of cells embedded in a thin layer of colloid, and is dark brown, red or purple. Porphyra has a disc-shaped holdfast and a filamentous rhizoid. It grows on rocks in the intertidal zone of shallow seas.

3. Where is laver mainly grown?

Laver is mostly distributed in coastal areas

The coastal areas of Fujian and southern Zhejiang mainly cultivate Porphyra hainanensis, while the northern areas mainly cultivate Porphyra yezoensis.

Xiapu County, the hometown of laver, is located in the eastern part of Fujian Province. It is one of the oldest counties in Fujian Province and the earliest region in southern my country to cultivate kelp and laver. As early as the Yuan Dynasty, there were records of Xiapu people cultivating laver. It is the hometown of laver in China and has the national geographical indication of "Xiapu Laver".

Xiapu has a unique natural environment and climatic conditions, with a long coastline, many natural independent harbors, a subtropical monsoon humid climate, and unique water temperature and water quality conditions, all of which are suitable for the growth of laver and kelp, and have created the special refreshing, smooth taste and high quality of Xiapu laver.
