Combined ecological floating bed and culture method thereof

Abstract

The invention relates to a combined ecological floating bed and a culture method thereof. The combined ecological floating bed falls into an upper layer, a middle layer and a lower layer. The upper layer is an aquatic plant area for planting halophilous terrestrial plants, the middle layer is an aquatic animal area for culturing aquatic animals, and the lower layer is for free-range filter feeding shellfish. The combined ecological floating bed is formed by series connection of combined ecological floating bed monomers. The combined ecological floating bed monomers are connected in series and then fixed to a timber pile so as to form the combined ecological floating bed, the four corners and the central position of which are respectively connected to a floating ball. The combined ecological floating bed and the culture method provided by the invention can comprehensively utilize the space levels of seawater pond water, integrate microorganism and plant remediation, by extending the food chain of a floating bed ecological system and strengthening the microbial enrichment characteristics of the floating bed, reduce culture diseases, improve the comprehensive benefits of culture, and simultaneously perform in-situ remediation on water, regulate the content of nitrogen and phosphorus of water and the pH value, and improve the transparency, etc.

Description

[0001] Technical field: [0002] The invention relates to the technical field of mariculture, in particular to a combined ecological floating bed and a cultivation method thereof. [0003] Background technique: [0004] In the ordinary mariculture process, the content of nitrogen, phosphorus and other elements in the water body will increase, resulting in eutrophication of the water body, the increase of phytoplankton and plants, and a series of consequences such as the decrease of dissolved oxygen in the water body, which will pollute the water body and affect the production. [0005] Common water bioremediation methods include microbial remediation, phytoremediation and ecological floating bed remediation. Microbial remediation is the earliest bioremediation method studied. The principle is that under aerobic or anaerobic conditions, microorganisms can decompose organic matter or other pollutants and release nutrients such as nitrogen and phosphorus. The high-efficiency ...

AI Technical Summary

Problems solved by technology

However, most macroalgae grow slowly and are easy to die and rot in the high temperature season in summer, and summer and autumn are the seasons when the water quality in aquaculture ponds is poor and disease-prone seasons occur, so there are still many unsatisfactory places to use phytoremediation to regulate water quality; Timely harvesting of large algae is more likely to cause secondary pollution

It is easy to cause the invasion of alien species; and the secretions of some large algae may have toxins, which will affect the aquatic animals in the breeding area
