The invention discloses a combined type ecological cycle planting and breeding
system. According to the invention, the
tail water discharged from the glass tank
fish tank culture area is subjected to microbiological treatment, then enters the vegetable cultivation
system and is biologically absorbed and filtered by vegetable root systems, the treated
wastewater is returned to the culture pond, and no
wastewater is discharged, so that the production requirements of high-quality fresh fishes and vegetables are met, and
nutrient loss which pollutes the environment is avoided;
beneficial bacteria are utilized in the breeding
tail water
system to adjust balance of bacterial phases and
algae phases in water and prevent deterioration of the
water environment caused by accumulation of residual feed and metabolites, and bacillus has the effects of preventing excessive accumulation of excrement, dead
algae and residual feed, promoting updating of the
algae phases, decomposing organic matters in water in time and improving
water quality. The
compound system of the
closed loop process has very obvious improvement and restoration effects on
water quality and substrate of the pond, can be used for large-scale production, is high in efficiency, and reduces the use of
water resources to a great extent.
