Novel ecological circulation fish and vegetable symbiotic system

Abstract

The invention provides a novel ecological circulation fish and vegetable symbiotic system. The system comprises a pond and a constructed wetland, wherein at least one side of the pond is provided with the constructed wetland; the constructed wetland comprises a subsurface flow wetland, a surface flow wetland and an ecological floating bed; the subsurface flow wetland and the surface flow wetland are arranged along the extending direction of the pond; the ecological floating bed is arranged on the surface flow wetland; a first type of aquatic animals are cultured in the pond; a second type of aquatic animals are cultured in the surface flow wetland; a first type of vegetables are planted in the subsurface flow wetland; and a second type of vegetables are planted in the ecological floating bed. According to the novel ecological circulation fish and vegetable symbiotic system, by developing and constructing the novel ecological circulation fish and vegetable symbiotic system, on one hand, water resource recycling is achieved, water resource waste is reduced, on the other hand, yield increasing and income creating are achieved, and an effective scheme is provided for solving the prominent problem of pond culture.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a novel ecological cycle fish-vegetable symbiosis system. Background technique [0002] In recent years, pond aquaculture has gradually occupied a core position in fishery development, and has also become the first choice of a large number of individual farmers. However, with the expansion of the industrial scale and the increase of aquaculture production, the problems of environmental pollution and waste of water resources have become more acute, and the contradiction between economic benefits and sustainable development has become more and more obvious. Contents of the invention [0003] The present invention proposes a new type of ecological cycle fish and vegetable symbiosis system, which is used to solve the increasingly acute problems of environmental pollution and waste of water resources in the prior art, as well as the increasingly prominent contradiction between e...
