photosynthetic bacterica powder(PSB)

The photosynthetic bacteria from breeding pond is a kind of solid biology preparation made by manual select-raise and reproduction via modern biological engineering technology. Its main characteristics include: good adaptability, composing much fungus, high bacteria quantity, rich nutrition, strong-clean water ability, high bait conversion efficiency fibe effect to improve water quality.

Widely used in freshwater and seawater breeding. It is the best choice for aquatic green breeding.

1.Main composition and content:

Rhodopseudomonas palustric, Rhodopseudomonas chlorobium, rhodospirillum an growth-promoting gene and carrier, PSB cell tatal≥200/g

2.Main function:

a. well absorb the harmful substance such as ammonia nitrogen, nitroso nitrogen, sulfureted hydrogen etc. Promoting the circulation of organic substance and purifying water.

b. Form the advantage bacterial colony, maintain the micro-zoology balance of water body, to restrain the reproduction of pathogeny microorganism, prevent the disease of aquatic overcome the defect of disinfector, be good for decomposing the harmful substance in water.

c. Culture the float animal, increase the nature bait, to reduce the bait dosage.

d. Increase the transparence of water body, promote the photosynthesis of floating plant and increase indirectly the oxygen.

e. Speed up the growth of aquatic, improve the metabolism of animal body, to strengthen its immunity system, increase the immunity and resistance to disease.

3. Usage and dosage:

a. activate for 2-4 hours with 30-40°C pond water, then dilute and evenly splash. Dosage for the first time: 1 kg in each 1mu×meter water, once every 10-15 days, then lower the dosage by 1/2.

b. For high temperature or rainy reason or worse water quality, using for 3 days continually, 1 kg in each 1mu×meter water. Then once 7-10 days and lower the dosage by 1/2.

c. As the open-mouth bait, before the young begin to open mouth, splash on the water surface. Dosage: 10 kg in each 1mu×meter water

d. Mix directly into the bait, dosage: for fish and shrimp 1.5-2.0% of bait, growth period 0.5-1.0% of bait; for eel, soft-shelled, turtle, river crab, prawn 1.5-2.0% of bait.
