Description
Technical field
The present invention relates to a kind of porphyra haitanensis seedling rearing room direct nursery technique.
Background technology
Porphyra haitanensis, popular name Thallus Porphyrae, black dish, be Chinese distinctive one kind can tame Sargassum, frond dark violet green slightly
Brown, lanceolar, sub- avette or long avette, long more than 12-30CM, property species in warm temperate zone is Zhejiang Province, China, Fujian and Guangdong edge
The Main Cultivation algae of bank, rich in proteins, polysaccharide and vitamin can be edible or medicinal.Porphyra haitanensis cultivation has had more than 30
The history in year, porphyra haitanensis production scale are little, and the production link such as seed rearing, mariculture and processing does not form fairly perfect
Industrial chain, seedling raise period are long, yield poorly, and labour force's input is more, and recruitment cost is high, cultivation density is uneven, and seed survives
Rate is low, and porphyra haitanensis yield poorly.Porphyra haitanensis nursery pond water, due to not having the water source that has selected, does not carry out effective water simultaneously
Matter is purified, and is caused to meet nursery needs well with water in nursery pond, is unfavorable for the stimulation and radiation of seed.
Content of the invention
The technical problem to be solved is：There is provided a kind of nursery effect good porphyra haitanensis seedling rearing room direct nursery work
Skill.
In order to solve above-mentioned technical problem, the technical scheme is that：Porphyra haitanensis seedling rearing room direct nursery technique, including
Following steps：The porphyra haitanensis for plucking are put into chilled storage below -15 DEG C of refrigerator-freezer by harvesting ripe porphyra haitanensis at the beginning of 3 months；To March
The middle ten days and the last ten days thaws, and the porphyra haitanensis of defrosting are put in container, and stirring allows the carpospore of maturation to be dispersed in water, by microscope meter
Number is sprayed onto on the shell in nursery pond；Half-light is processed three days, changes water once, need progressively to give out light according to illumination after three days, is tied
Close the in good time regulating illumination of Changes in weather；To August at the beginning of, stimulated with the anti-sea water of high powered water pump, disposably radiated 3-5 little
When, through counting, off line number is selected according to conditions such as water temperature weathers, keep lace curtaining humidity 3-5 hours to marine linked network, adopt
Semi-floating nursery, 4 hours dry dew, 8 hours evenings, in water, were done dew in 4 hours, were kept for 12-15 days, opened in water 8 hours daytimes
3-5 days beginning, lace curtaining was without lifting rope, it is ensured that Seedling can be contacted with water, and lace curtaining hangs within 6-8 days, then lace curtaining both sides all buttonhole selvages, root
According to the height that sea height adjusts lace curtaining in good time, it is ensured that the not tender contact sandy beach of lace curtaining, should clear up in time during lace curtaining attachment silt, half
For preventing chlorella from should freeze in time in floating seedling raising process, during semi-floating nursery, water temperature controls, below 28 DEG C, to see within 12-15 days
After seedling puts net to seawater breeding.
In order to preferably solve above-mentioned technical problem, the further technical scheme of the present invention is：Water in the nursery pond
It is to obtain water after purified treatment, water purification process step includes：March chooses the underground of the deep left and right of 9-11 rice under sand grains
Water, at 9-11 DEG C or so, pH value enters sedimentation tank precipitation one to the temperature of subsoil water in 8-8.5 or so, after subsoil water is pumped
More than week, it is desirable to fine, the harmful organism in water can Lock-out.
It is an advantage of the invention that：Above-mentioned porphyra haitanensis seedling rearing room direct nursery technique, seedling raise period are short, and cultivation density is uniform,
Yield is high, and labour force is few, reduces recruitment cost, accelerates porphyra haitanensis industry to standardization, scale.Use in nursery pond simultaneously
Water in do not contain the material harmful to porphyra haitanensis nursery, effects of purification quality is good, can meet nursery needs well, with profit
In the stimulation and radiation of seed, the survival rate of seed is high, substantially increases Thallus Porphyrae yield.
