The invention relates to a coated compound fertilizer, in particular to a totally biodegradable coated compound fertilizer and a preparation method thereof. The coated compound fertilizer consists of a coated layer and a compound fertilizer core. The main body of the coated layer is polylactic acid and / or polybutylene succinate. The coating process adopts fluidized bed spraying-coated technology, and comprises the following steps: dissolving polylactic acid and / or polybutylene succinate in trichloromethane, adding carboxymethylcellulose, urease and / or nitrification inhibitor, organic and / or inorganic conditioner in the solution, spraying and coating the surfaces of the fluidized compound fertilizer granules after uniformly mixing the mixture under the stirring of a stirrer to form the uniform and complete organic polymeric membrane layer. The process has the advantages of easy implementation, and capacity of effectively slowing down the release of the fertilizer nutrient to the outside and the conversion rate of nitrogen in soils, effectively controlling the release and conversion of the fertilizer nutrient in soils, and reducing the pressure on environment caused by the rapid release of nutrient. The coated material can be totally biodegradable, and the degradation products have no secondary pollution to the environment.

The invention relates to aquaculture animal disease control technologies, and particularly relates to a vibrio anguillarum divalent vaccine, a preparing method thereof and a using method of the vaccine. The vaccine is a bacterial suspension mixture of a vibrio anguillarum 01 serotype and a 02 serotype. The vibrio anguillarum 01 serotype and the 02 serotype are deposited in the general microbiology center of the China Committee for Culture Collection of Microorganisms on December 7, 2012 and respectively have an accession number namely CGMCC No.6942 and CGMCC No.6944. The divalent inactivated vaccine can protect susceptible fishes from being infected by pathogenic vibrio anguillarum. The divalent vaccine broadens the vaccine protection range, effectively irritates cultured fishes to generate specific immune response, and effectively provides immune protection for diseases. Preparation of the divalent vaccine is low in cost of used materials and safe to animals and the environment.
