Fish and vegetable symbiosis system and special photosynthetic bacterium agent for aquaculture

Abstract

The invention relates to the technical field of ecological cycle, in particular to a fish and vegetable symbiotic system. The invention provides the fish and vegetable symbiosis system, which is characterized in that specially cultured autotrophic bacteria are added and conveyed to a fish pond for fish culture, aquaculture water is periodically pumped and conveyed into a cultivation system, and the aquaculture water returns to a clean water pond after being absorbed by vegetables and filtered by a sewage discharge pond, so that ecological circulation is realized, and waste resource utilizationis realized; during the period, the autotrophic bacteria decompose a large amount of ammonia nitrogen generated by aquaculture into nitrite, and then the nitrite is decomposed into nitrate by nitrifying bacteria to be absorbed and utilized by plants. The fish and vegetable symbiotic system provided by the invention enables animals, plants and microorganisms to achieve ecological balance, is a sustainable, circulating, pollution-free and zero-emission low-carbon production mode, can realize large-density culture of fish, and meanwhile, planted crops are high in growth vigor, high in nutrition,simple in system structure, high in integration, convenient to clean and suitable for popularization, and huge popularization values and development prospects are realized.

Description

Technical field [0001] The invention relates to the technical field of ecological circulation, and more specifically, to a fish-vegetable symbiosis system. Background technique [0002] In traditional aquaculture, with the accumulation of fish excrement and the increase of ammonia nitrogen in the residual water body of fish food, the toxicity gradually increases, leading to an increase in the incidence of fish. The fish-vegetable symbiosis system achieves an ecological balance between animals, plants, and microorganisms. There are three points where fish-vegetable symbiosis is most attractive to consumers: the first planting method can prove innocence. Because there are fish in the fish-vegetable symbiosis system, no pesticides can be used. A little carelessness will cause the death of fish and beneficial microorganisms and the collapse of the system. The second fish-vegetable symbiosis is cultivated away from the soil, which avoids heavy metal pollution in the soil. Therefore, ...
