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

Abstract

The invention discloses polypeptide fish guano which is prepared from the following effective components in percentage by weight: 50-60% of high-protein organic matters, 2-5% of a compound microbial strain, 5% of biochemical potassium fulvic, 10-15% of an inorganic nitrogenous fertilizer, 10-15% of an inorganic phosphatic fertilizer, 5-10% of an inorganic potash fertilizer, 3-6% of minor elements of sea water, 0.5-1% of polypeptide and 1-2% of rare earth. The invention further discloses a preparation method of the polypeptide fish guano. The product is fast in dissolving rate and high in utilization ratio, can be used for directionally cultivating zooplankter such as beneficial algae and rotifers and providing comprehensive and abundant nutrition to fishes. Polypeptide can be directly absorbed by fishes, so that rapid growth of fishes is promoted.

Description

technical field [0001] The invention relates to a polypeptide fish fertilizer for promoting the rapid growth of fish and a preparation method of the fish 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] The fertilizers commonly used in aquaculture mainly include organic fertilizers and inorganic 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 use of organic fertilizers is also limited ...
