Production method of microbial fish guano

Abstract

The invention provides a production method of a microbial fish guano. The production method comprises the following steps: fermenting materials, drying, crushing, and adding inorganic fertilizer and solid photosynthetic bacteria. Because all the organic fertilizers are fermented, the invention has a good water solubility and can fast culture pelagic organisms in the water substance, thereby providing adequate feedstuff to fishes and shrimps; the invention improves the culture water environment, and reduces the harmful substances in water, such as ammonia, nitrogen, nitrite, hydrogen sulfide and the like; the invention can realize the intensive alternate-breeding culture and greatly increase the yield per unit culture area, and the yield can be increased by more than 40% based on the current service condition; and the invention has the advantages of low cost, safety, high efficiency, environmental friendliness and no pollution, thereby ensuring the production of pollution-free green food.

Description

technical field [0001] The invention relates to a production method of fish fertilizer, in particular to a production method of microbial fish fertilizer. Background technique [0002] Fertilization is one of the effective measures to improve the production of aquaculture water in ponds and reservoirs. To raise fish, you must raise the water first. Due to the different fertilization environment and species and breeding objects, there is a big difference between water surface fertilization and land fertilization. The majority of farmers have been using traditional inorganic fertilizers and organic fertilizers for fertilization. Inorganic fertilizers have a single nutrient component , the fertilizer effect is short, and it is easy to make the water body eutrophic. Organic fertilizers decompose slowly, have many pathogenic bacteria, and have low utilization rate. The excess sinks to the bottom of the water and decomposes in an anaerobic environment to produce harmful substance...

To raise fish, you must raise the water first. Due to the different fertilization environment and species and breeding objects, there is a big difference between water surface fertilization and land fertilization. The majority of farmers have been using traditional inorganic fertilizers and organic fertilizers for fertilization. Inorganic fertilizers have a single nutrient component , short fertilizer effect, easy to make water eutrophication

Organic fertilizers decompose slowly, have many pathogenic bacteria, and have low utilization rate. The excess sinks to the bottom of the water and decomposes in an anaerobic environment to produce harmful substances such as ammonia, nitrogen, nitrite, hydrogen sulfide, etc., especially at high temperatures where fish and shrimp grow faster Season, this kind of contradiction is quite prominent. In order to avoid this contradiction, fishermen have to reduce the breeding density and reduce the amount of fertilizer, but this will lead to a decrease in unit breeding output, and the water quality has not been fundamentally improved. The fish and shrimp grow slowly and are easy to be infected. Diseases, polluting the water body after a large number of drugs, and the drugs remaining in the fish and shrimp greatly threaten people's health
