Method for collecting and cultivating offspring seed of wild monostroma nitidum

Abstract

The invention disclosed a method for collecting and cultivating offspring seed of wild monostroma nitidum. The method comprises the following steps: building an appropriate seed bed and adopting an appropriate seed net to ensure that zoospores of offspring seed of wild monostroma nitidum are attached to ropes of the seed net for growing into thallus, so as to build appropriate living and growing space for wild monostroma nitidum; then managing the seed bed to ensure high yield of the wild monostroma nitidum on the seed bed and high content of chlorophyll of the wild monostroma nitidum and less sediment containing of gained wild monostroma nitidum, thereby improving the quality of the wild monostroma nitidum; the method solves the defects of long seed raising period in a man-made chamber, slow growth, higher input cost, high management difficulty and the like; the method can be applied to large scale production, the seed bed can be repeatedly used, the production cost is low, the thallus on the seed net can be easily collected to reduce the waste of mudflat and reef collection; in addition, the obtained monostroma nitidum is natural wild monostroma nitidum and is ideal green food.

Description

technical field [0001] The invention relates to a method for collecting and cultivating seaweed seed, in particular to a method for collecting and cultivating wild reef seed. Background technique [0002] Reef film Monostroma nitidum belongs to Chlorophyta, Ulva, Reef Filmaceae, and Reef Film genus. Its body length is generally about 5cm. It is soft, thin, delicious, and can be eaten fresh. It has attractive volatile substances and has no fishy smell. The fresh-to-dry ratio of the finished dish is 7:1. It can also be dried in the sun and stored for a long time. It can be used as soup, sauce and condiment. Reef film has high dietary fiber content, rich nutrition, rich in seaweed polysaccharides, fatty acids, vitamins, amino acids, inorganic salts and trace elements, etc. It is the most edible green algae. The nutrients of the reef membrane are easily absorbed by the human body, which is good for cell activation, and has good preventive and curative effects on cardiovascular ...

Problems solved by technology

Artificially propagated reef seedlings collect gametes around April and then go to the sea for cultivation in September. It takes about 5 months to raise seedlings. During such a long seedling raising process, it is difficult to control the continuous changes of factors such as temperature and light, which increases the The risk of raising seedlings, and requires corresponding seedling raising equipment and manpower and material resources for professional management, so the time for seedling raising is longer, the risk of raising seedlings is greater, and the cost of raising seedlings is higher

However, the chlorophyll content of wild reef films directly pasted on tidal flats or reefs is low, and the scale of wild reef films is small and the number of reef films that can be collected is also small. It is difficult to collect and wasteful when collecting, and the collected reef films often contain Small mud and sand affect the quality of wild reef membranes
