Description

Technical Field

[0001] The present invention relates to the field of planting technology, and in particular to a fish-vegetable symbiotic planting system and a planting method. Background Art

[0002] Fish-vegetable symbiosis is the use of aquaculture discharge water to provide nutrition for plants. By feeding nitrogen source feed to fish, and then using the discharge water from farmed fish for plant irrigation, both fish and vegetable products can be obtained. This planting method has the characteristics of high water and ammonia source utilization efficiency, no use of chemical fertilizers and antibiotics, and environmental friendliness. It is a new type of circular farming technology that combines aquaculture and plant cultivation. It is also a sustainable agricultural development method and an effective way to effectively solve the agricultural ecological environment.

[0003] For example, the patent document with Chinese patent application number 202410382586.6, classification number A01G31 / 02, and publication date 2024.05.14 discloses a fish-vegetable symbiotic planting device and a method of using the same, wherein the middle section of the suction pipe extends smoothly through a folding assembly, a winding frame is provided at the upper end of the water inlet cavity, one end of the waterproof cloth is rotatably wound on the winding frame, the winding frame and the folding assembly are linked by a transmission assembly, and a cleaning device with a waterproof cloth and a suction pipe that slide synchronously is provided, so that the sliding direction is guided by the arc-shaped base frame so that the fish float upward, and the waterproof cloth is used for separation to avoid the water turbidity caused by the lifting of fish feces and other organic matter, thereby protecting the fish from the influence of the brush, and at the same time, through the transmission ratio of the relative bevel gear, the synchronous operation of the folding assembly and the winding frame is realized, so that the waterproof cloth and the suction pipe are adapted to the lateral sliding of the arc-shaped base frame, synchronous cleaning is realized, and the linkage adjustment of multiple sets of driving parts is avoided, which greatly improves the convenience of cleaning.

[0004] The above document drives the arc-shaped base frame to slide at the bottom of the breeding tank through a driving component, and synchronously drives the brush to rotate and clean, stirs up impurities, and uses a water pump and a suction pipe to suck out the sewage mixed with impurities. While absorbing water, the qualified water quality in the pre-storage tank is poured into the water inlet cavity. At the same time, the tempering tank is used to adjust the concentration and temperature of ammonia compounds in the impure sewage, prepare qualified breeding water, and transport the tempered water to the pre-storage tank; it only collects organic impurities produced by fish, but it does not recycle the fixed organic impurities produced by fish and the plant residues produced in the planting area. For the planting area, plants need additional light and heat for auxiliary irradiation at night. If external light sources are used directly, it will lead to a waste of energy as a whole, and the planting area cannot be adaptively adjusted according to the irradiation of sunlight, which will lead to unbalanced plant growth in the planting area.

[0036] like Figure 5 As shown, the present invention also provides a planting method of a fish-vegetable symbiotic planting system, comprising the following specific steps: S1 starts the pump 8 on the connecting pipe 34 to pump the fish excrement solution in the breeding pond 1 into the solid-liquid separation box 3 for standing; S2 After standing for solid-liquid separation, the regulating valve on the second connecting pipe 32 is opened to allow the separated water-fertilizer solution in the solid-liquid separation box 3 to flow into the water-fertilizer storage tank 7 for storage, and then the water-fertilizer solution in the water-fertilizer storage tank 7 is pumped to the water-fertilizer supply pipe in the planting layer 37 through the pump 8 on the connecting pipe 1 31 to irrigate the plants with water and fertilizer; S3 opens the switch valve on the connecting pipe 3 33, so that the solid organic matter separated in the solid-liquid separation box 3 flows into the fermentation tank 4, and then the agitator 6 is driven by the driving motor z1 to rotate, so that the plant residues collected from the planting area and the solid organic matter are fully mixed and fermented; S4 drives the gear 41 to rotate on the rack 12 through the dual drive motor 9, and adjusts the height of the electric telescopic rod 14 and the electric telescopic rod 2 38 at the same time, so that the rack 12 always slides in contact with the slide groove 11 at the same height, thereby driving the support rod 36 to rotate around the hinge connected to the ground, and adjusting the angle of the planting layer 37 according to the irradiation angle of the sunlight 18, so that the sunlight 18 irradiates each planting layer 37, prolonging the irradiation time of the plant receiving the sunlight 18.

The arc-shaped reflective plate is fixedly connected to the end of the connecting rod. The arc-shaped reflective plate is provided with an opening arranged downwardly. More than two support rings arranged along the length direction of the arc-shaped reflective plate are arranged in the opening. The thermoluminescent tube and the heat-conducting tube are arranged in the support ring. The thermoluminescent tube is located below the heat-conducting tube. The bottom of the heat-conducting tube is abutted against the thermoluminescent tube. The outer side of the heat-conducting tube is wrapped with a thermal insulation layer. The heat-conducting tube is connected to the other end of the thermal insulation tube.

9. The fish-vegetable symbiotic planting system according to claim 1, characterized in that: A Fresnel light guide is arranged on the top of the breeding shed located above the breeding pond.

10. The planting method of the aquaponics planting system according to claim 1, characterized in that: The following steps are involved: S1 starts the pump on the connecting pipe 4 to pump the fish excrement solution in the breeding pond into the solid-liquid separation box for standing; S2 After standing still until the solid and liquid are separated, the regulating valve on the second connecting pipe is opened to allow the separated water-fertilizer solution in the solid-liquid separation box to flow into the water-fertilizer storage tank for storage, and then the water-fertilizer solution in the water-fertilizer storage tank is pumped to the water-fertilizer supply pipe in the planting layer through the pump on the first connecting pipe to irrigate the plants with water and fertilizer; S3 opens the switch valve on the connecting pipe 3, so that the solid organic matter separated in the solid-liquid separation box flows into the fermentation tank, and then the agitator is driven by the driving motor to rotate, so that the plant residues collected from the planting area and the solid organic matter are fully mixed and fermented; S4 drives the gears on the racks to rotate through dual drive motors, and adjusts the heights of the electric telescopic rods 1 and 2 at the same time, so that the racks always slide in the slide grooves at the same height, thereby driving the support rods to rotate around the hinges connected to the ground, and adjusting the angle of the planting layer according to the angle of sunlight, so that the sunlight can be irradiated on each planting layer, extending the exposure time of the plants to sunlight; S5 pumps water from the water storage tank into the heat exchange coil through the pump on the insulation pipe, so that the water in the heat exchange coil passes through the insulation pipe and then enters the heat conduction pipe, transporting the heat in the fermentation tank to the planting layer, and releasing heat to the thermoluminescent tube through the heat conduction pipe, making the thermoluminescent tube glow, increasing the lighting time of the plant and promoting plant growth.
