Efficient aquatic fertilizer for improving water quality and preparation method of efficient aquatic fertilizer

Abstract

The invention discloses an efficient aquatic fertilizer for improving the water quality. The efficient aquatic fertilizer is composed of the following effective constituents by weight percent: 60-70% of high-protein organic materials from animals and plants, 2-5% of compound microorganism strains, 5% of biochemical fulvic acid potassium, 5-10% of inorganic nitrogenous fertilizer, 5-10% of inorganic phosphatic fertilizer, 2-5% of inorganic potassic fertilizer, 3-6% of seawater microelement and 1-2% of rare earth. The invention also discloses a preparation method of the efficient aquatic fertilizer for improving the water quality. The efficient aquatic fertilizer is high in solution rate and high in utilization rate. By utilizing the efficient aquatic fertilizer, propagation of baits of aquatic animals can be promoted, beneficial algae can be cultured directionally, full and rich nutrients can be provided for fishes to further inhibit fish diseases, the water quality can be improved simultaneously, and dissolved oxygen in the water can be increased.

Description

technical field [0001] The invention relates to a high-efficiency aquatic fertilizer capable of improving water quality and a preparation method of the fertilizer. Background technique [0002] Under specific environmental conditions such as light and temperature, the supply of dissolved nutrients in water directly determines the rate and output of primary production in water, and ultimately affects the output of farmed fish. [0003] At present, the commonly used fertilizers in aquaculture mainly include organic fertilizers, inorganic fertilizers and biological compound fertilizers. [0004] As a traditional fertilizer, organic fertilizer has the advantages of comprehensive nutrition, but the fertilizer effect is slow, the process of being used by plankton is long, and a large amount of oxygen in the water body is consumed in the process of decomposition and mineralization, which is easy to cause water pollution and harm fish. The growth of species is unfavorable, and the ...

Problems solved by technology

[0004] As a traditional fertilizer, organic fertilizer has the advantages of comprehensive nutrition, but the fertilizer effect is slow, the process of being used by plankton is long, and a large amount of oxygen in the water body is consumed in the process of decomposition and mineralization, which is easy to cause water pollution and harm fish. The growth of species is unfavorable, and the use of organic fertilizers is also limited by seasons, mainly used as base fertilizers in winter and spring when the water temperature is low

[0005] Compared with organic fertilizers, inorganic fertilizers are faster to fertilize, but their functions are relatively single. Large-scale application will also pollute water quality, cannot control harmful bacteria, and cannot effectively prevent fish diseases, thus affecting the water quality of aquatic products.
