Aquaculture biofertilizer and preparation method thereof

Abstract

The invention discloses an aquaculture biofertilizer and a preparation method thereof. The aquaculture biofertilizer is composed of sodium humate, urea, calcium superphosphate, bacillus subtilis and clinoptilolite powder. The method includes: mixing fermentation composite bacteria with water evenly to obtain a diluted bacteria liquid; adding the diluted bacteria liquid into an organic fertilizer, and mixing the materials evenly, piling up the mixture in heaps, and performing cyclic overturn to obtain a primary fermentation object; then adding ferment bacteria, conducting fermentation till complete decomposition, and carrying out low temperature drying and crushing to obtain a secondary fermentation object; and finally, adding an inorganic fertilizer, trace elements, amino acid, compound vitamin, actinomyces and photosynthetic bacteria, conducting granulation into balls, and performing sorting to obtain biological organic aquaculture nutrient powder. The biofertilizer provided by the invention can be supplied to aquatic organisms for direct use, also can combine with harmful substances in water substrate to remove toxicity, and at the same time can enhance algal metabolism and increase dissolved oxygen of water. The preparation method is simple, and is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to a biological fertilizer and a preparation method thereof, in particular to an aquaculture biological fertilizer and a preparation method thereof. Background technique [0002] Due to the low water temperature in spring, the lack of nutrients such as nitrogen, phosphorus and potassium in the water body, the number of beneficial algae in the water body is small, which makes the water body difficult to fertilize in spring; in some ponds, the water color is thin and green moss grows on the bottom of the clear pool. In addition, during the breeding process, problems such as thinning of the water body, reduction of dissolved oxygen, and unstable water environment due to changes in weather or environment will also occur. Some fertilizers need to be added to achieve the purpose of fertilizing water. However, if only chemical fertilizers are used for water body cultivation, the nutrient elements are single, and although the water body c...
