Efficient biological fish fertilizer for aquaculture and preparation method of fish fertilizer

Abstract

The invention provides an efficient biological fish fertilizer for aquaculture and a preparation method of the fish fertilizer. The efficient biological fish fertilizer comprises the following ingredients: 30-45 parts of inorganic fertilizer, 15-25 parts of rice bran, 5-10 parts of distiller grain, 10-20 parts of tea-leaf, 15-25 parts of potamogeton crispus powder, 5-18 parts of pine needle powder, 0.2-1 part of microelement, 0.5-1.5 parts of saccharomycete, 0.5-1 part of aspergillus niger, 0.4-0.8 parts of bacillus, 2-5 parts of corn straw biomass charcoal and 1-3 parts of medical stone powder. The biological fish fertilizer has a high total protein content and is complete in nutrition at the same time; a content proportion of the microelement, amino acid, vitamins and the inorganic fertilizer is reasonable; the fish fertilizer can provide rich and comprehensive nutrition for multiple aquatic livestock, phytoplankton and zooplankton; and at the same time, the biological fish fertilizer can effectively improve a culture environment and immunity of the aquatic livestock, and reduce the occurrence of diseases.

Description

technical field [0001] The invention relates to the technical field of fish fertilizer, in particular to a high-efficiency biological fish fertilizer for aquaculture and a preparation method thereof. Background technique [0002] Currently, in my country's aquaculture industry, the deterioration of the water environment has become a bottleneck for the sustainable development of the aquaculture industry. In order to obtain a higher yield in a certain water body, people have to put a large amount of bait, fertilizer, fishing medicine, etc. into the water body to meet the requirements of fish growth and disease control. This breeding method characterized by strong feeding and heavy fertilizer increases the decomposition and transformation load of nitrogen, phosphorus and organic matter in the water body. Due to poor water quality control and management, microbial decomposition is not smooth, material circulation and energy flow in the water body are blocked, residual bait, org...

Problems solved by technology

[0003] Traditional fertilizers have their own advantages and disadvantages. Among them, organic fertilizers have more comprehensive nutrients and moderate and long-lasting fertilizer effects. However, the composition is complex, the fertilizer effect changes greatly, and it is easy to increase the content of organic matter in the water body. Even after fermentation, it will bring a lot of Organic slag, causing water pollution and easy to cause flooding and other phenomena, and there are many harmful bacteria, which is easy to cause bacterial and virus disease flooding; inorganic fertilizers decompose quickly, fertilizer efficiency is fast, the composition is relatively simple and easy to determine, and the dosage is small. The operation intensity is small, and the pollution to the water body is light, but the fertilizer effect is not long-lasting, the water solubility of the active ingredients is poor, it is easy to change the physical and chemical properties such as the pH value of the water body, and it is easy to settle and cause the bottom mud to harden, and the algae phase is bad. Mainly green algae, it is difficult for farmed animals to digest and absorb
