Problems solved by technology

[0006] Oligosaccharides are used as immune enhancers in the field of aquatic seedlings. For example, the invention patent with the publication number CN1736162A "A method for preventing and treating kelp seedling shedding and rotten seedlings with alginic acid oligosaccharides" and the invention patent with the publication number CN102599173A "Agar Gum The application and application method of oligosaccharides in Porphyra Immune Enhancer" are all carried out in the breeding stage, but the labor intensity of the processing process is high and the processing cost is high

Embodiment 1

[0020] The agar oligosaccharide is made into a solution with a concentration of 100 μg / ml with seawater, and the net curtain (the density of the net curtain is 400 ascospores per centimeter) with conchospores is soaked in the seawater solution for agar oligosaccharide and left to stand for 1.5 h. The light intensity is 15000Lx. After the net curtain is processed, it is hung on the raft frame in the sea area.

Embodiment 2

[0025] Prepare agar oligosaccharide with seawater to make a solution with a concentration of 50 μg / ml, soak the net curtain with conchospores (the density of the net curtain is 300 conchospores per centimeter), soak in the sea water solution for agar oligosaccharide, and let it stand for 1h . The light intensity is 30000Lx. After the net curtain is processed, it is hung on the raft frame in the sea area.

Embodiment 3

[0030] Make the agar oligosaccharide into a solution with a concentration of 250 μg / ml in seawater, and soak the net curtain with conchospores (the density of the net curtain is 600 conchospores per centimeter) in the seawater solution for agar oligosaccharide, and let it stand for 2 hours . The light intensity is 10000Lx. After the net curtain is processed, it is hung on the raft frame in the sea area.

Abstract

A method for promoting porphyra haitanensis conchospore adhesion and germination comprises the step 1 that agaro-oligosaccharides is prepared with seawater to be 50-250 micrograms per milliliter in concentration and is mixed to be uniform, so an agaro-oligosaccharide and seawater solution is obtained; the step 2 that a porphyra haitanensis web curtain where conchospore seedlings are adhered is soaked in the prepared agaro-oligosaccharide and seawater solution and stays standing for 0.5 h-2 h, wherein illumination intensity is 33,000-80,000 Lx; the step 3 that the density of the seedlings on a web is detected, and the seedlings are moved from a warehouse to be placed into the sea. The method is simple in technology and operation, capable of lowering labor intensity and simplifying working procedures, low in treatment cost and meanwhile capable of effectively improving the germination capacity of adhered conchospores, improving the growth state of porphyra haitanensis seedlings and enhancing the resistance to pathogenic microorganisms and bad environments. Besides, the quality of porphyra haitanensis conchospores is good, and production benefits are greatly improved.

Description

technical field [0001] The invention relates to a method for promoting the attachment and germination of porphyra conchospores, in particular to a method for promoting the attachment and germination of conchospores released from shell filaments of Porphyra alba in a room. Background technique [0002] Altar seaweed is a natural healthy food, and it is a unique traditional cultivated economic seaweed in my country. It has a history of nearly 40 years of artificial cultivation and production. At present, the cultivated area is nearly 300,000 mu, the output exceeds 200,000 tons, and the total output value is nearly 2 billion yuan. The altar laver industry is characterized by less investment, many people involved, a high proportion of manual operations, and good social and economic benefits. [0003] The whole artificial cultivation process of algae porphyra includes inoculating shells with fruit spores and free filaments—cultivating shell filaments—promoting ripening and relea...
