Embodiment Construction

[0012] The present invention is further described below:

[0013] A kind of sargassum full-artificial seedling raising technology, the conditions of its process steps are: (1) cultivation and collection of planting vegetables: adopt raft type horizontal hanging type at sea, 10000-20000 strains of planting vegetables are stocked per mu, and the cultivation water layer is 30cm~ 50cm, the cultivation goal is to fully develop the reproductive receptacle and reach sexual maturity. (2) Emission and fertilization of sperm and eggs: After 1 hour to 2 hours of drying in the shade to stimulate the growth of vegetables, it will promote the growth of vegetables in Sargassum, the emission of sperm and eggs, and the growth of vegetables. The ratio of cabbage ♀ plants to ♂ plants is 1:1, put them into seawater pools to collect fertilized eggs, during the process of collecting fertilized eggs, the seawater should be stirred continuously to promote the release and fertilization of eggs, and dry...

Abstract

The present invention relates to seedlings raising technology for seaweed, especially relates to a artificial seedlings raising technology for rattailed algae, comprising breeding and gathering colza, discharging and fecundating of sperms and germ cell, gathering oosperms, cultivating sprout inside indoor, temporarily breeding sprout on the sea, after flatly breeding on a catamaran 30-40 days, could reach length of 2-3cm, density of 8-10 plants each centimeter. The present invention could obtain stable yield and could produce two crops a year.

Description

Technical field: [0001] The invention relates to seaweed seedling raising technology, in particular to a sargassum artificial seedling raising technology. Background technique: [0002] Sargassum thunbergii is a kind of brown algae, which is a warm temperate seaweed. In nature, it is mainly distributed on reefs in the intertidal zone, and its leaves are fresh, tender, and rich in nutrients. According to analysis, Sargassum contains 14.4% crude protein, 0.31% crude fat, 57.0% total sugar, 4.4% crude fiber, and 23.4% ash; the content of essential amino acids, unsaturated fatty acids, minerals and trace elements is rich and reasonable. It is also reported (养辉三: Algae の Life History Integration) that Sargassum also has the effect of repelling roundworms parasitic in the human body, and can be made into an insect repellent like the famous ascarid repellent seaweed - partridge. Feeding juvenile ginseng with sage algae powder, or feeding ginseng and adult ginseng with compound fe...
