Problems solved by technology

In pools with high-density conchospore water, the density is high and the time is long, which is prone to poor water quality conditions and inconsistent lighting conditions on the upper and lower layers, which also affects the quality of attached seedlings.

Embodiment 1

[0038] A kind of altar porphyra contospore seedling picking method, comprises the following steps:

[0039] (1) Porphyra laver shell spores release:

[0040] Place the shells that have been stimulated and have the shell filaments of Porphyra algae in plastic mesh bags, and place 4500 to 4800 shells in each bag; put the mesh bags in the conchospore release pool and inject clean seawater, and place 2 shells per square meter. The bag is filled with shell filaments, and the depth of seawater is 30-35cm; the water temperature in the conchospore release pool is 2-3°C higher than that at the time of stimulation, and the salinity of the water body is 5‰ lower than that at the time of stimulation; check the density of conchospores at any time, check Fully stir the water body to disperse the conchospores evenly; when the conchospore density in the water body reaches 100,000 / mL, pass the seawater containing a large amount of concospores in the concospore release pool into the conchospore...

Embodiment 2

[0047] A kind of altar porphyra contospore seedling picking method, comprises the following steps:

[0048] (1) Porphyra laver shell spores release:

[0049] Place the shells that have been stimulated and have the shell filaments of Porphyra algae in plastic mesh bags, and place 5,000 to 5,500 shells in each bag; put the mesh bags in the conchospore release pool and inject clean seawater, and place 2 shells per square meter. The bag is filled with shell filaments, and the depth of seawater is 35-40cm; the water temperature in the conchospore release pool is 2-3°C higher than that at the time of stimulation, and the salinity of the water body is 5‰ lower than that at the time of stimulation; check the density of conchospores at any time, check Fully stir the water body to disperse the conchospores evenly; when the conchospore density in the water body reaches 100,000 / mL, pass the seawater containing a large amount of concospores in the concospore release pool into the conchospo...

Abstract

The invention discloses a seedling-adhering method for porphyra haitanensis conchospores. The method comprises the following steps: setting up a conchospore spreading pond, a conchospore collecting pond and a conchospore seedling-adhering pond, wherein the conchospore collecting pond is located at a higher position, and the conchospore seedling-adhering pond is located at a lower position; uniformly spraying seawater containing conchospores in the conchospore collecting pond onto a seedling curtain in the conchospore seedling-adhering pond by using potential energy difference through a porphyra haitanensis conchospore water-spray seedling-adhering device. The porphyra haitanensis conchospore water-spray seedling-adhering device is used, and therefore the method disclosed by the invention has the advantages that the densities and the spore growth statuses of the same batch are uniform, the seedling-adhering conditions are improved, the yield and the production value are favorably ensured, and the management intensity of seedling raising is lightened.

Description

technical field [0001] The invention relates to a method for collecting seedlings of shell spores of algae porphyra, belonging to the technical field of seaweed breeding. Background technique [0002] Altar seaweed is one of the economical seaweeds with the highest output value in the world. It 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, and oligosaccharides. , dietary fiber and trace elements and other substances and minerals have special effects on improving sub-health. 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 have important ecological restoration and protection significance for the marine environment. [0003] The traditional method of picking conchospore seedlings of Porphyr...
