Embodiment

[0018] Embodiment, a kind of Sargassum seed production technology is to use the law of sexual reproduction to carry out indoor seed breeding, and the young sporophytes formed after the mature seed algae discharge sperm eggs under natural conditions are attached to the artificial substrate , for indoor cultivation. Including the selective collection of algae, the stimulation and release of algae, the collection of young sporophytes, the attachment of seedlings to the seedlings, cultivation and release into the sea; the selective collection of algae is when the daily maximum water temperature in the growth area of ​​Sargassum reaches 20-23 °C For collection, select the algae with a length of more than 30cm, yellowish brown, with genital receptacle, strong development, no genital receptacle shedding and tip decay as seed algae; the stimulation of algae seeding is released, and the stimulation methods include running water and drying in the shade. Stimulation is to promote the syn...

Abstract

The invention discloses a seedling producing technique for rat-tailed algae, applying to seedling breed in-door according to sexual reproduction law, including: selecting and collecting the seed algae, stimulating and diffusing the seed algae, collecting the juvenile sporophyte, culturing and catadromousing seedlings, provided an artificial seedling producing technique for rat-tailed algae, dissolving the current shortcoming problem of the rat-tailed algae seedlings.

Description

1. Technical field [0001] The invention belongs to the technical field of seaweed cultivation, and relates to a technology for producing artificial seedlings of large economical algae-Sargassum. 2. Background technology [0002] Sargassum is an important economical algae, and its value is reflected in four aspects. (1) Medicine and health care: lectins, antibacterial active substances and plasma substitutes can be extracted; its polysaccharides are often used as immune enhancers, brown algae polyphenols are considered natural antioxidants of marine organisms; sargassum is dried and ground into powder For the treatment of goiter, lymphatic tuberculosis and angina pectoris. (2) Chemical industry: It can extract chemical raw materials with high economic value such as mannitol and iodine. (3) Aquaculture: It can be used as bait for sea cucumber, wrinkled plate abalone, and bay scallop seedlings and cultivation. (4) Ecology: Sargassum has a strong ability to enrich inorganic a...
