First, the application dose and precautions of PSB in aquatic products and livestock and poultry breeding. PSB is beneficial to a variety of aquaculture animals, especially the nursery stage, the effect is particularly obvious, with a survival rate of 20 to 60% higher than the control for adult fish fattening, increased production by about 20%, the feed coefficient decreased by about 20%, individual 15% weight gain, more than 800 yuan per mu. And without any side effects. Nursery dosage: 100 grams per square meter. Use once every 10 days. Adult fish fattening: For the first time, use 7 kg an acre, and later use 4~5 kg/mu, and use it once every 15 days. Fish fry or sick fish bath: Dilute 10 times with photosynthetic bacteria and put the fry or diseased fish for 15 minutes. After the medicinal bath, the survival rate of fish and shrimp can be increased by 90%, such as myxobacterial disease, gill disease, survival rate of 60-100% for printing diseases, watery mildew disease, red fin disease, and scratch disease survival rate of nearly 100%. There is no medicinal bath side effect. The amount of feed: 5% of the liquid used in the seed feed, 3% of the liquid in the adult fish feed, and 3 to 5% of the liquid in the livestock feed are now mixed. If you use solid PSB, it can be used in feed for a long time. Application method: Divide the appropriate amount of water and spread it over the whole pool. If the lime is used for 2 hours, then PSB is better. Can not be used together with disinfectant, water disinfection can be used after 1 week. In sunny days, the water temperature is better than 20 degrees. Liquid PSB should be used up on the day after mixing in the material. Acidic water is easy to make the fish sick and is not conducive to the growth of PSB. Quicklime should be used to adjust the pH of the water. (3) Add 5% of fry, 3% of adult fish, and 3%-5% of livestock. Add 3% of feed water. (4) Planting rice and wheat: 5 kg foliar spray per acre. Rice seedling stage and booting stage are each used once; wheat winter fertilizer and jointing stage are each used once. Rapeseed: Basal mu with 15 kg roots. Before the expedition, the mu was sprayed with 15 kilograms of foliar. Fruits and vegetables: 10 kilograms per acre, the seedling stage diluted rooting one time, budding period spraying once. Leafy vegetables: 20 kg per mu, rooting or foliar spray during the growth period, once in 7 days. Flowers: After the transfer, 40 kilograms of roots were used for mu. During the growth period, 20 kg of spray is applied per mu, once every 15 days. Tea tree: 80 kg of sowing base fertilizer. Winter fertilizer with 40 kilograms of roots. Before the germination period, 20 kg of roots were used for mu. When the leaves grow, the mu is sprayed with 15 kg, once every 15 days. Fruit trees: winter fertilizer acres with 40 kg watering roots. After the new leaf grows into acre, it is sprayed with 20 kilograms of foliar. (5) Environmental wastewater treatment dosage: 200-1000ppm. 2. Use method (1) Dilution photosynthetic bacteria solution 20-30 times the whole pool evenly spilled. (2) The bacteria solution is absorbed into the zeolite powder or mixed with fine soil and then thrown into the tank. (3) The broth liquid is mixed and fed. (4) Dilute the broth 10 times and soak the fingerlings. (5) seed dressing, rooting, foliar spray. 3. Precautions (1) Do not mix with disinfectant. Disinfect the body of water for 1 week before use. (2) Before use, the bacteria solution light more than 10 hours, the use of better. (3) Good results are obtained when the water temperature is above 20°C on sunny days. (4) Stir the feed on the day of feeding. (5) The dosage and continuity of use should be flexible, because photosynthetic bacteria can play the biggest role in the formation of dominant communities in water bodies. (6) The application effect is best when the water is alkaline. Acidic waters tend to make the fish sick. Quick lime or caustic soda should be used to adjust the pH to neutral or partial alkali. (7) Photosynthetic bacteria can not be stored in metal containers. (8) When fry is cultivated, Quanchiposa should be used 7 days before the seedlings enter the pond to facilitate the growth of plankton. (9) At the germination stage, the application effect is best.
