Efficient environment-friendly aquaculture fertilizer and preparation method thereof

Abstract

The invention discloses an efficient environment-friendly aquaculture fertilizer and a preparation method thereof. The fertilizer is prepared from 50-200 parts of a biological organic fertilizer and atrace element additive, and the biological organic fertilizer and the trace element additive are weighed in parts by weight. The preparation method comprises the following steps: uniformly mixing fermenting mixed bacteria and water to obtain a diluted bacterial solution; adding the diluted bacterial solution into the organic fertilizer, uniformly mixing the mixture, piling the mixture, and overturning the mixture cyclically to obtain a primary fermented object; then adding enzyme microorganisms to ferment till the primary fermented object is fully rotten, and carrying out low-temperature drying and crushing to obtain a secondary fermented object; and finally, adding an inorganic fertilizer, trace elements, amino acid, radix angelicae, astragalus membranaceus, compound vitamins, actinomycetes and photosynthetic bacteria, carrying out prilling and balling, and carrying out sorting to obtain the biological organic aquaculture nutritional material powder. The fermenting matrix of the biological organic fertilizer is garden wastes which are originated from the surrounding environment of a breeding system, so that natural substances are recycled; the efficient environment-friendly aquaculture fertilizer is more environmentally friendly, and meanwhile, a microelement additive is also added to promote growth of fishes.

Description

technical field [0001] The invention relates to a fertilizer and water agent and a preparation method thereof, in particular to a fertilizer and water agent for aquaculture ponds and a preparation method thereof. Background technique [0002] In the aquaculture industry, fertilizer is a very important breeding factor. Reasonable fertilization can promote the growth of plankton in the water. It is an effective method to increase the output of fish ponds and increase the benefits of fish farming, and it is also one of the important measures to develop fishery production. Fertilization is a key part of the entire process from fry and fingerling cultivation to adult fish rearing. [0003] Fertilizers mainly affect the growth of fish by affecting water quality, the growth of plankton and directly serving as bait for fish. When the water is clear, there will be no fish. Tests have shown that fertilization can promote the reproduction and growth of plankton, effectively reduce the...
