An expandable and contractible fish and vegetable symbiosis breeding device

Abstract

The invention discloses a telescopic aquaponics breeding and planting device and relates to the technical field of breeding and planting facilities. The telescopic aquaponics breeding and planting device comprises a water tank body, a waterproof film and a vegetable-planting floating plate, wherein vegetable planting holes are formed in the vegetable-planting floating plate; the telescopic aquaponics breeding and planting device is characterized in that two outer brackets are arranged on two outer sides of the water tank body; more than two inner brackets are arranged on the inner side of the water tank body; more than one expanding and contracting mechanisms capable of enabling the water tank body to horizontally expand and contract are arranged between the outer brackets and the inner brackets and between the inner brackets; the waterproof film is fixed on the outer brackets and the inner brackets; the waterproof film can be expanded, folded and contracted along with the water tank body. The telescopic aquaponics breeding and planting device is ingenious in structure, simple and convenient to operate and convenient to contract and transfer, can be applied to commercial large-scale and large-area planting, can also be applied to household ornamental breeding and planting, has high popularization value and is especially suitable for application and popularization on temporary idle land.

Description

technical field [0001] The invention relates to the technical field of seed cultivation facilities, in particular to an expandable and contractible fish and vegetable symbiotic seed cultivation device. Background technique [0002] With the increasing scarcity of land resources and fresh water resources, fish and vegetable symbiosis breeding technology has been widely used. Fish and vegetable symbiosis is a new type of breeding technology, which ingeniously combines the two production methods of aquaculture and fruit and vegetable production. It can realize fish farming without water changes and no water quality concerns, and vegetables can grow normally without fertilization. It has good economic and social benefits such as land saving, water saving, and ecological pollution-free. [0003] The aquaponics device in the prior art mainly has two modes, one is to use existing ponds for transformation, and increase vegetable planting facilities on the water surface to achieve t...
