Abstract
The invention provides a culture solution for promoting growth of thalassiosira and a culture method. The culture solution per liter comprises 5-15 mg of ammonium nitrate, 0.5-4mg of sodium dihydrogen phosphate, 0.05-0.4 mg of ferric citrate and 20-60 mg of sodium silicate. According to the culture solution for promoting growth of thalassiosira, the raw materials are common, and the cost is low; the culture method is simple, the culture density of the thalassiosira in an open pond is effectively improved, and the application prospect is wide.
Description
Technical field
The invention belongs to aquaculture field, especially relate to a kind of promote hailian seaweed to grow nutrient solution and cultural method.
Background technology
Diatom as shellfish, prawn larvae and the part fish young direct open-mouthed bait and cultivate the nutritional fortification food of the secondary food organism such as wheel animalcule, halogen worm, copepods, can not be substituted in the status of aquatic fry growing.Hailian seaweed has adaptable advantage as wild algae kind, and it has abundant affects composition, wherein the content of indispensable amino acid and fish meal quite even more excellent, therefore, hailian seaweed is widely used in the process of economic marine animal artificial breeding, becomes one of gordian technique improving seed seed output and quality.Lack in the market specially for the product that hailian seaweed is cultivated, the cultural method in laboratory is complicated, and cost is high, is not suitable for algae and opens pool cultivated condition.
Summary of the invention
In view of this, the present invention be intended to propose a kind of promote hailian seaweed to grow nutrient solution and cultural method, the cultivation density of hailian seaweed effectively can be provided, and be applicable to hailian seaweed industrialization and open pool cultivated.
For achieving the above object, technical scheme of the present invention is achieved in that
Promote the nutrient solution that hailian seaweed grows, comprise following composition, ammonium nitrate 5 ~ 15mg/L, SODIUM PHOSPHATE, MONOBASIC 0.5 ~ 4mg/L, ironic citrate 0.05 ~ 0.4mg/L, water glass 20 ~ 60mg/L.
Preferably, comprise following composition, ammonium nitrate 8 ~ 12mg/L, SODIUM PHOSPHATE, MONOBASIC 1 ~ 3mg/L, ironic citrate 0.1 ~ 0.3mg/L, water glass 30 ~ 50mg/L.
Preferably, comprise following composition, ammonium nitrate 9 ~ 11mg/L, SODIUM PHOSPHATE, MONOBASIC 1.5 ~ 2.5mg/L, ironic citrate 0.15 ~ 0.25mg/L, water glass 35 ~ 45mg/L.
Preferably, comprise following composition, ammonium nitrate 10mg/L, SODIUM PHOSPHATE, MONOBASIC 2mg/L, ironic citrate 0.2mg/L, water glass 40mg/L.
The present invention also provides a kind of and utilizes the method that the nutrient solution of hailian seaweed growth carries out hailian seaweed cultivation that promotes as above, each component is fully dissolved in the seawater being heated to 60 DEG C, adopts the numerous mode of outdoor expansion to cultivate.
Preferably, each component is fully dissolved in the seawater being heated to 60 DEG C.
Preferably, the culture environment of hailian seaweed is, temperature 33-37 DEG C, intensity of illumination 2000-4500Lux, salinity 25-32ppm, pH value 7-8.
Relative to prior art, nutrient solution and the cultural method of promotion hailian seaweed growth of the present invention have following advantage:
(1) nutrient solution of promotion hailian seaweed growth of the present invention, raw material is all comparatively common, and cost is lower.
(2) cultural method of the present invention comparatively simple, effectively raise hailian seaweed and open pool cultivated density, application prospect is comparatively wide.
