A kind of rotation utilization method of altar purple shell filaments

Abstract

The invention discloses an alternate utilization method of porphyra haitanensis shell conchocelis. According to the method, in alternate utilization for the first time, mature shell conchocelis with porphyra haitanensis sporangia is moved to the North for conchospore picking; in alternate utilization for the second time, shell conchocelis obtained after conchospore picking subjected to alternate culture for the first time is completed is moved to the South for secondary cultivation, and after sporangia are mature, conchospore picking is continued; in alternate utilization for the third time, culture for the third time is continued on shell conchocelis obtained after conchospore picking of subjected to alternate utilization for the second time is completed, and after sporangia are mature, the porphyra haitanensis shell conchocelis can be used as naturally proliferated offspring seeds of local porphyra haitanensis. By means of the method, the technical defect that the porphyra haitanensis demand of the northern area is great, but offspring seeds are insufficient in source can be overcome, and furthermore, the technical defect that the mature period of porphyra haitanensis shell conchocelis in the southern area is earlier than the conchospore picking period, so that sporangia are aged can be overcome.

Description

technical field [0001] The invention relates to a rotation utilization method of algae seaweed shell filaments, and belongs to the technical field of seaweed breeding. Background technique [0002] Altar laver is one of the economic seaweeds with the highest output value in the world, and it is an important cultivated seaweed in the south of the Yangtze River in my country, with a breeding area of ​​more than 500,000 mu. Altar seaweed is rich in nutrition and delicious in taste. The content of crude protein in the dry product is more than 30%, and it contains vitamin A, vitamin C, a variety of essential amino acids, polysaccharides, oligosaccharides, dietary fiber and trace elements and other substances and minerals. , has special effects on improving various diseases of the modern population. Large-scale cultivation of Porphyra can consume a large amount of nutrients such as nitrogen and phosphorus in seawater, reduce the degree of eutrophication in the coastal waters, and...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a rotation utilization method of seaweed shell filaments in view of the deficiencies in the prior art, which can solve the problem that there is a large demand for seaweed seedlings in the northern region, but the source of seedlings is insufficient. The technical defect can also solve the technical defect of aging sporangia caused by the maturity stage of the shell filaments of Porphyra laver in the southern region, which is earlier than the stage of picking seedlings of conchospores
