The invention discloses a feed composite antioxidant. The feed composite antioxidant comprises following compounds by weight: 20-35% of an antioxidant, 1-5% of an emulsifier, 1-10% of a synergist and 50-70% of a carrier. The feed composite antioxidant has advantages of significant antioxidation effects, strong efficacy, high performance cost ratio, simple production process, high benefit, low equipment investment, no "three-waste" pollution, and the like.

The invention discloses a method for purifying low-carbon-nitrogen-ratio domestic sewage by a biological fermentation coupling artificial wetland system. The system consists of a microbial fermentation system and a wetland unit which are connected in series. The method comprises the following steps: fermenting straws by adopting microorganisms to obtain a microbial fermentation broth; then adding the microbial fermentation broth into the artificial wetland; mixing the microbial fermentation broth with domestic sewage to obtain a mixed solution, and treating the mixed solution by using the artificial wetland to obtain purified domestic sewage. According to the method, the straws are fermented, so that the straws are reasonably utilized; the resource utilization rate is increased; the carbon source release capacity is high; the carbon-nitrogen ratio of the sewage is effectively improved; and the sewage treatment efficiency is improved.

The invention discloses a method for preparing a composite microbial flocculating agent by using composite flocculating bacteria, and belongs to the technical field of sewage treatment. The application of the microbial flocculating agent is limited by the disadvantages of high cultivation cost and non-ideal treatment effect of a single flora. Strains are activated separately, then compounded, andinoculated to a fermentation medium, fermental cultivation is carried out, a liquid supernatant is removed after centrifugalization, and the composite microbial flocculating agent is obtained; the composite microbial agent comprises pseudoalteromonas (Pseudoalteromonas hodoensis) S2-M-5 and pseudoalteromonas (Pseudoalteromonas nigrifaciens) S2-F-5 of which the preservation number is CGMCC No. 14429. The method for preparing the composite microbial flocculating agent by using the composite flocculating bacteria has the advantages that the flocculation effect is better, the flocculation rate canreach 93% or above, and the action condition is stable.

The invention relates to the field of plant tissue culture, and discloses a tissue culture method for improving the survival rate of bananas. The tissue culture method comprises the following steps: (1) disinfecting a culture room; (2) selecting explants; (3) sterilizing the explants; (4) carrying out initial induced culture; (5) performing subculture; (6) hardening seedlings. The tissue culture method disclosed by the invention uses a plant treatment liquid to disinfect the explants so as to improve the survival rate of the explants in the tissue culture process, and further uses cassava alcohol wastewater to replace the common MS medium, thereby being capable of effectively lowering the tissue culture cost. The invention further provides a tissue culture method which can improve the survival rate of the banana explants and has no damage to the explants, and further can lower the cost.
