Releasing method for porphyra haitanensis seedlings

Abstract

The invention discloses a releasing method for porphyra haitanensis seedlings. The method includes drying lobate bodies of the porphyra haitanensis in the shade, preparing into carpospores liquid, performing inoculation into shells, growing naturally into shell filaments, and performing cultivation to a mature-stage shell filaments; and placing the mature-stage shell filaments in stone marsh in an intertidal zone with a water depth of 10-20cm after the ebb tide and in reefs in the intertidal zone one hour before the flood tide for natural release, performing broadcast sowing on the mature-stage shell filaments in a neritic region for the natural release, and suspending the mature-stage shell filaments in a mesh bag on the lower portion of a positioned float in an abyssal region for the natural release, wherein the neritic region refers to an ocean area with a water depth of 6-10m after the ebb tide, the abyssal region refers to an ocean area with a water depth larger than10m after the ebb tide, the lower portion of the positioned float is submerged for 0.5-1.5m under the water level, and the natural release continues for 2-3 years. According to the method, the germplasm of the porphyra haitanensis can be improved, natural resources of the porphyra haitanensis can be recovered, and ecological environment of the seaweed can be restored.

Description

technical field [0001] The invention relates to a restoration technology of altar laver population, in particular to a method for releasing altar laver seedlings. Background technique [0002] Altar seaweed is rich in nutrition and delicious in taste, and is deeply loved by people. At present, most of them are self-propagating and self-supporting free-range breeding of scattered small households, that is, the altar laver breeding generally inoculates the filaments in the shells at the beginning of April every year to cultivate the shell filaments, and collects the conchospores in September, and then inoculates the shells. Cultivate seedlings in the breeding sea area to grow up. With more and more self-propagating and self-supporting farmers of algae laver, wild algae laver resources are gradually shrinking, the number and quality of wild algae laver populations are declining, and the ecological environment of seaweed is destroyed, resulting in deterioration of the living e...

Problems solved by technology

With more and more self-propagating and self-supporting farmers of algae laver, wild algae laver resources are gradually shrinking, the number and quality of wild algae laver populations are declining, and the ecological environment of seaweed is destroyed, resulting in deterioration of the living environment of marine animals and a decline in the number; and algae laver In order to quickly cultivate filaments during breeding, the temperature of the cultivation water generally exceeds 30°C, which leads to the gradual degradation of the Porphyra germplasm; basically the same breeding environment and culture environment will also affect the reduced adaptability and disease resistance of Porphyra altar, and the gradual deterioration of the Porphyra germplasm. Degenerate, also prone to nutritional deficiencies, poor growth
