Embodiment 1
[0016] A kind of nutrient salt that promotes the rapid and high-density growth of thalassira, the nutrient salt includes the following components in grams per ton of seawater: iron citrate 1.5g / ton, sodium silicate 20g / ton , Potassium dihydrogen phosphate 2g / ton, urea 40g / ton and disodium edetate 20g / ton.
[0017] The method for cultivating Thalassiosira using the above-mentioned nutrient salts that promote the rapid and high-density growth of Thassistras comprises the following steps:
[0018] S1. The seawater is passed through the sedimentation tank to precipitate debris, and the sand filter is filtered. After entering the reservoir, 2g of bleaching powder is added to each ton of seawater to sterilize the original organisms. After aeration for 24 hours, it is ready for use;
[0019] S2, pump the seawater in the reservoir into the culture tank, add 0.8g sodium thiosulfate per ton of seawater to remove chlorine, stir and dissolve sodium thiosulfate with an appropriate amount o...
Embodiment 2
[0023] A kind of nutrient salt that promotes the rapid and high-density growth of Thalassiosira, the nutrient salt includes the following components in g per ton of seawater: 2 g / ton of iron citrate, 30 g / ton of sodium silicate, Potassium dihydrogen phosphate 3g / ton, urea 50g / ton and disodium edetate 30g / ton.
[0024] The method for cultivating Thalassiosira using the above-mentioned nutrient salts that promote the rapid and high-density growth of Thassistras comprises the following steps:
[0025] S1. The seawater is passed through the sedimentation tank to precipitate debris, and the sand filter is filtered, and then after entering the reservoir, 5g of bleaching powder is added to each ton of seawater to sterilize the original organisms, and after aeration for 48h, it is ready for use;
[0026] S2, pump the seawater in the reservoir into the culture tank, add 1.5g of sodium thiosulfate per ton of seawater to remove chlorine, stir and dissolve sodium thiosulfate with an appro...
Embodiment 3
[0030] A kind of nutrient salt that promotes the rapid and high-density growth of thalassira, the nutrient salt includes the following components in grams per ton of seawater: iron citrate 1.8g / ton, sodium silicate 25g / ton , Potassium dihydrogen phosphate 2.5g / ton, urea 45g / ton and disodium edetate 25g / ton.
[0031] The method for cultivating Thalassiosira using the above-mentioned nutrient salts that promote the rapid and high-density growth of Thassistras comprises the following steps:
[0032] S1. The seawater is passed through the sedimentation tank to precipitate debris, and the sand filter is filtered, and then after entering the reservoir, 3.5g of bleaching powder is added to each ton of seawater to sterilize the original organisms, and after aeration for 36h, it is ready for use;
[0033] S2, pump the seawater in the reservoir into the culture tank, add 1.2g of sodium thiosulfate per ton of seawater to remove chlorine, stir and dissolve sodium thiosulfate with an appro...
