Photosynthetic bacteria is a kind of high-tech biological product. Its bacterial cells contain more than 60% protein, and it is rich in B vitamins, amino acids and growth promoting factors. It is a high-quality and safe nutritive feed additive, and it has been widely used in aquaculture. . Photosynthetic bacteria can release trypsin, activate shrimp immune system, enhance resistance to disease, promote metabolism, and thus improve feed efficiency. In addition, photosynthetic bacteria can also degrade and remove harmful hydrogen sulfide, phenols, amines and other compounds in the water, and absorb heavy metal ions, so that the shrimp pond water quality and sediment quality can be purified. Practice has proved that when the dissolved oxygen in the water of shrimp farming decreases, the pH value decreases, and the water quality deteriorates, as long as 5 kg of photosynthetic bacteria solution (concentration is between 1 and 2 billion bacteria per milliliter) is applied to the shrimp pond with a depth of 1 meter per acre, That is to say, it can make the water color stable and have higher transparency than the shrimp pond in the same conditions, which is beneficial to increase the PH value, increase the dissolved oxygen in the water, especially at the bottom of the shrimp pond, and increase the vigor of the shrimp body, which can increase production by 20% to 30%. Photosynthetic bacteria should be applied before the shrimps are released and the water quality should be improved. They should be applied once every 10 to 15 days until shrimps are harvested. However, photosynthetic bacteria should not be used together with disinfectants such as lime and bleach.
Application method: First, the photosynthetic bacteria and clean fine sand mixed after the whole pool spread; Second, the direct dilution of photosynthetic bacteria liquid Quanchiposa; Third, add 3% photosynthetic bacteria liquid feed shrimp feed.
