Abstract

The invention discloses nutrient salt for promoting rapid high-density growth of sea-chain algae and a culture method, and relates to the technical field of aquaculture. The nutrient salt is preparedfrom the following components: ferric citrate, sodium silicate, monopotassium phosphate, urea and ethylene diamine tetraacetic acid. According to the nutrient salt disclosed by the invention, the ureais added as one part of the nutrient salt, so that the dosage of other components in the nutrient salt can be reduced; the urea is lower in cost, so that the overall cost of the nutrient salt is reduced, and the culture cost of the sea-chain algae is reduced; and meanwhile, the rapid high-density growth of the sea-chain algae is promoted through vitamin C and carbon dioxide in air.

Example Embodiment

[0015] Example 1

[0016] A nutritious salt that promotes the rapid high density growth of sea chain, contains the group G number in each ton of seawater, including the following components: iron citrate 1.5g / ton, sodium silicate 20g / ton Potassium dihydrogen phosphate 2g / ton, urea 40g / ton and sodium diethylenediamine 20g / ton.

[0017] The following steps of the following steps are included using the above-mentioned steps in the following steps:

[0018] S1, sequentially sequentially deposits the debris, the sand filter is filtered, and after entering the water storage tank, 2G bleaching powder is added to the seawater to sterilize the original organism, after aeration 24h, spare;

[0019] S2, pumping the seawater in the reservoir into the culture pool, add 0.8 g of sodium thiosulfate for chloride according to the seawater per ton, stir the sodium thiosulfate and mix well after mixing, splash in the culture pool, where sulfur The addition of sodium sulfate is determined by the chloride content in seawater. From less to more, the chloride content can be detected by the residual chlorine detection kit to ensure that the chloride content in the final seawater is 0.025 mg / L 3 min in the air, add 0.8 g of vitamin C according to the sea water per ton;

[0020] S3, with this component G number in each ton of water, stirred the iron citrate 1.5g / ton to stir well, stir splash in the culture pool, 20g / ton of sodium silicate, potassium dihydrogen phosphate After 2g / ton and urea 40g / ton were mixed with an appropriate amount of water, stirred in the culture pool, and stirred the sodium diethylenediacene tetra acetate and mixed with an appropriate amount of water and mixed into the culture pool, and then transferred Air 3min;

[0021] S4, in the culture pool, 10L seawater is taken into 1 L Sea parasylitencae, which is cultured at a temperature of 25 ° C and the light intensity of 4000 lux.

[0022] Example 2

[0023] A nutritious salt that promotes the rapid high density growth of sea parasylism, contains the group G count in the sea water, including the following components: iron citrate 2g / ton, sodium silicate 30g / ton, Potassium phosphate 3g / ton, 50 g / ton of urea and sodium diethylenediamine 30g / ton.

[0024] The following steps of the following steps are included using the above-mentioned steps in the following steps:

[0025] S1, sequentially deposited the debris, the sand filter is filtered, and after entering the water storage tank, 5g bleach is added to the water, and the anti-chemical organism is blended. 48h, spare;

[0026] S2, pumping the seawater in the reservoir into the culture pool, add 1.5 g of sodium thiosulfate to the sodium thiosulfate, stir the sodium thiosulfate and mix well, splash in the culture pool, among the sulfur The addition of sodium sulfate is determined by the chloride content in seawater. From less to more, the chloride content can be detected by the residual chlorine detection kit to ensure that the chloride content in the final seawater is 0.025 mg / L Air 8 min, then add 1.5 g of vitamin C according to the sea water per ton;

[0027] S3, with this component G number in the sea water, stir the calcium citrate 2g / ton to stir well, stir splash in the culture pool, 30g / ton sodium silicate, 3g of dihydrogen phosphate / Ton and urea 50g / ton were mixed with appropriate amount of water and mixed in the culture pool, and stirred the sodium ethylenedialamine tetra acetate 30g / ton and mixed with an appropriate amount of water, splashled in the culture pool, and then transfer air 8min;

[0028] S4, in the culture pool, 2L seractomye algae seeds in 12L sea water, cultured in an environment of 32 ° C and the light intensity of 8000lux.

[0029] Example 3

[0030] A nutritious salt that promotes the rapid high density growth of sea parasylism, contains the group G number in each ton of water, including the following components: iron citrate 1.8g / ton, 25g / ton sodium silicate , 2.5 g / ton of potassium phosphate, 45 g / ton of urea and 25g / ton of dice tetracetate.

[0031] The following steps of the following steps are included using the above-mentioned steps in the following steps:

[0032] S1, sequel sequentially deposits the debris, the sand filter is filtered, and after entering the water storage tank, 3.5 g of bleak powder is added to the sea water to sterilize the original organism, after aeration 36h, spare;

[0033] S2, pumping the seawater in the reservoir into the culture pool, add 1.2 g of sodium thiosulfate for sodium thiosulfate, stir the sodium thiosulfate and mix well, splash in the culture pool, among the sulfur The addition of sodium sulfate is determined by the chloride content in seawater. From less to more, the chloride content can be detected by the residual chlorine detection kit to ensure that the chloride content in the final seawater is 0.025 mg / L , Enter the air for 5 minutes, then add 1.2 g of vitamin C according to the sea water per ton;

[0034] S3, with the number of bonus Gs in the sea water, stir the iron citrate 1.8g / ton to stir well and dissolve, splash in the culture pool, 25g / ton of sodium silicate, potassium dihydrogen phosphate 2.5g / ton and urea 45g / ton were mixed with appropriate amount of water, splashled in the culture pool, and mixed with sodium ethylenedialamine tetra acetate with a proper amount of water and mixed in the culture pool, and then Into the air for 5 min;
