Description

Technical Field

[0001] The utility model relates to the technical field of fish-plant symbiotic breeding devices, in particular to a fish-plant symbiotic breeding device. Background Art

[0002] The fish-plant symbiotic breeding device is a device that integrates the planting function and the fish-raising function in one, and it can meet people's leisure and entertainment needs of planting flowers and plants and raising fish at the same time.

[0003] For example, an improved fish-plant symbiotic ecosystem disclosed in the Chinese patent No. ZL202223138275.0 proposed by the applicant in the past includes: a filtration module, a planting module and a water circulation module, wherein the planting module is fixed on the top of the filtration module, and the water circulation module is connected to the filtration module and the planting module through a hose, and the planting module includes: a planting trough and a planting cup, and the planting module is equipped with at least one layer of planting trough, and a diversion trough for distributing water is provided on the top of the planting module, and the diversion trough transports water to the diversion trough through the water circulation module, and a diversion port for water to flow to the planting cup is provided inside the diversion trough, and a drainage trough is provided on the diversion port for facilitating the outflow of water, and the water level in the diversion trough reaches the height of the diversion port before it starts to flow to each row of planting troughs respectively. This method will not cause uneven distribution due to insufficient water source and affect plant growth.

[0004] However, although this technical solution can utilize the diversion trough for diversion and avoid uneven distribution due to insufficient water source affecting plant growth, it was found during use that this technical solution still has certain shortcomings; for example, the bottom surface of the joint plug at the bottom of the diversion trough is a plane. When the water source flows to the bottom surface of the diversion trough, the water easily disperses around the bottom surface of the diversion trough, resulting in the water source being difficult to drip quickly and effectively into the planting cup, which to a certain extent affects the efficiency of the plant roots in the planting cup in absorbing water and affects the growth of the plant.
