Rice-fish symbiosis-aquaculture coupled complex planting and breeding system and breeding method

Abstract

The invention discloses a rice-fish symbiosis-aquaculture coupled complex planting and breeding system and a breeding method. The system is a new type separated rice-fish culture rice field-pond complex system, a plurality of functional units are communicated with each other by the aid of a novel water circulation technology, and a latticed long or square pond complex ecosystem is built. The method includes the steps: arranging water circulation system pipelines and performing water circulation by the aid of ditches or high-position ponds; setting up the complex planting and breeding system, building a rice field breeding system and an aquaculture system and mutually communicating the systems through water circulation of drainage pipelines or the ditches; performing accurate breeding and perfectly combining and complementing planting and breeding; performing biological integrated control and rice pest control by the aid of a rice-fish culture mode and spider group protection. The problems of over-fertilization, emission pollution, aquaculture industry sewage discharge and water source shortage are solved.

Description

technical field [0001] The invention belongs to an ecological planting and breeding system, and relates to a new paddy field comprehensive planting and breeding system, in particular to a breeding method coupled with an aquaculture system and a rice-fish symbiosis system. Background technique [0002] At present, the status of fishery resources is not optimistic. Whether it is freshwater or seawater, China's aquaculture industry relies heavily on offshore fishery resources, showing a high-carbon, high-nitrogen, and low-quality production model. The traditional single-pond mouth regulates water ecology. Integrated mixed culture There is no room for large growth in model output, especially in the case of heavy pollution of external water quality, endogenous nutrition can no longer be effectively adjusted through polyculture, water quality is easy to deteriorate, and there is an urgent need for a sustainable ecological comprehensive farming model that complements different farmi...

Problems solved by technology

[0005] In order to overcome the above-mentioned defects of the prior art, the object of the present invention is to provide a rice-fish symbiosis-aquaculture coupled compound planting and breeding system and a breeding method, which is a new paddy field-pond compound system for split-pond rice-fish co-production. The water cycle technology realizes the interconnection between multiple functional units and constructs a grid-shaped pond complex ecosystem, as shown in the attached figure 2 As shown, solve the problems of excessive fertilization and pollution discharge in rice planting industry, as well as the problem of sewage discharge and lack of water source in aquaculture industry
