Composite culturing device and method suitable for urban household

Abstract

The invention discloses a composite culturing device and method suitable for an urban household.The culturing device comprises a fishpond and a soilless cultivation plantation bed located above the fishpond; an inclined plane and a containing cavity are formed in the fishpond, and a connecting pipe, a pump, an output pipe and a water return pipe are connected between the containing cavity and the soilless cultivation plantation bed; an overflow opening is formed in the upper edge of the soilless cultivation plantation bed, and the inner diameter of the water return pipe is smaller than that of the output pipe; cover plates are arranged on the soilless cultivation plantation bed in a covering mode; solar panels are arranged on the cover plates, the outer surface of the fishpond and the outer surface of the soilless cultivation plantation bed, the solar panels are connected with an accumulator, and the accumulator is connected to the pump through a controller.The culturing method comprises the steps that water in the fishpond is pumped into the soilless cultivation plantation bed through the pump, and water is purified in the soilless cultivation plantation bed and flows back into the fishpond.According to the composite culturing device and method suitable for the urban household, residual bait and excrement of aquatic animals are decomposed through water circulation and microorganisms, nutrient is provided for plants, and the water flowing back into the fishpond is purified through plant root systems and the action of the microorganisms.

Description

technical field [0001] The invention relates to a cultivation device and a cultivation method. Background technique [0002] Food safety is one of the problems existing in the existing society. Eating with peace of mind is what we are currently pursuing. Therefore, the combination of soilless cultivation of vegetables on the balcony and fish farming equipment was born in response to needs. Using the small space at home, it is easy to It is easy to grow various green vegetables, bean sprouts and other healthy foods at home. [0003] With the vigorous development of aquaculture, high-density aquaculture has become the main aquaculture method, and the fish output per unit area has been greatly increased, and high consumption and high input of water, electricity, feed, fertilizer, medicine, etc. are exchanged for high output. Mainly, its own pollution is serious, and a large amount of aquaculture wastewater discharge will cause adverse effects on the surrounding ecological envi...

Problems solved by technology

[0003] With the vigorous development of aquaculture, high-density aquaculture has become the main aquaculture method, and the fish output per unit area has been greatly increased, and high consumption and high input of water, electricity, feed, fertilizer, medicine, etc. are exchanged for high output. Mainly, its own pollution is serious, and a large amount of aquaculture wastewater discharge will cause adverse effects on the surrounding ecological environment

According to relevant research reports, in the cultivation of edible fish, 5% to 10% of the bait artificially fed is not used, and a large amount of residual bait and pollutants formed by fish feces are directly discharged into the environment along with the aquaculture water body, which aggravates the surrounding environment. The eutrophication of rivers, lakes and coastal waters, which leads to the decline of water quality and the death of aquatic animals; the feed additives and drugs used in aquaculture directly affect the environment, leading to the increase of drug resistance of non-target species, which directly threatens human beings Own health; use of other drugs such as insect repellents and egg-laying hormones and chemicals such as fertilizers and algicides can disrupt population structure and their toxicity can affect biodiversity
