A feed pipe 2 is arranged in the middle of the box body 1, and water, nutrient solution, disinfectant, etc. are added into the box body 1 through the feed pipe 2. The seedbed is fixedly arranged on the inner side of the upper part of the box body 1. The seedbed comprises a horizontally arranged first support net 3 and a plurality of funnel parts 4 spaced below the first support net 3. The flower cultivation substrate is placed on the first support net 3. A plurality of air holes are spaced on the side wall of each funnel part 4, and a waterproof and breathable film is fixedly arranged on each ventilation hole. The air holes and the waterproof and breathable film are used to increase the air permeability of the funnel part. A plurality of infiltration irrigation pipes 6 are spaced and fixedly arranged on the first support net 3, such as Figure 1As shown, multiple infiltration irrigation pipes 6 are arranged at equal intervals along the length direction of the box body 1. Each infiltration irrigation pipe 6 is arranged along the width direction of the box body 1. Infiltration holes are provided along the length direction of the infiltration irrigation pipe 6, and filter membranes are provided on the infiltration holes. The filter membranes can prevent the flower cultivation substrate from blocking the infiltration holes.

The water inlet of the water pump 7 is communicated with the inside of the box body 1 through a water inlet pipe, and the water outlet is communicated with multiple infiltration irrigation pipes 6 through a water outlet pipe 8. A first one-way valve is provided on the water outlet pipe 8. The water pump 7 is used to pump the liquid in the box body 1 into the infiltration irrigation pipes 6, and the infiltration of the flower cultivation substrate is realized through the infiltration holes on them. The first one-way valve controls the liquid to only flow from the water outlet pipe 8 to the infiltration irrigation pipes 6. The return water tank 9 is fixedly arranged below the funnel part 4. The top of the return water tank 9 is communicated with the bottoms of multiple funnel parts 4 through a return water pipe 10. A second one-way valve 11 is provided on the return water pipe 10. The second one-way valve 11 controls the liquid to only flow from the return water pipe 10 to the return water tank 9. A drain pipe 12 is provided at the lower part of the return water tank 9. A third one-way valve 13 is provided on the drain pipe 12. The third one-way valve 13 controls the liquid to only flow from the return water tank 9 into the box body 1.

[0023] During use, first inject an appropriate amount of water, nutrient solution and disinfectant into the box body 1 through the feed pipe 2, configure the liquid according to the preset requirements according to the types of cultivated flowers and substrates, then turn on the water pump 7 and the first one-way valve, and use the water pump 7 to infiltrate the flower cultivation substrate through the water inlet pipe, the water outlet pipe 8 and the infiltration irrigation pipes 6 until the liquid level reaches the preset height. Then turn off the water pump 7 and the first one-way valve, and let the liquid remain in the flower cultivation substrate for a preset time. Then open the second one-way valve, so that the excess liquid in the flower cultivation substrate is preliminarily collected through the funnel part 4 and then flows into the return water tank 9 through the return water pipe 10. Then close the second one-way valve 11. When the return water deposits in the return water tank 9 for a preset time, then open the third one-way valve 13, so that the return water in the return water tank 9 enters the box body 1 again to realize circulation. Finally, close the third one-way valve 13, and a tidal infiltration irrigation process is completed. Since multiple funnel parts 4 are erected in the upper space of the box body 1, and the funnel parts 4 are provided with ventilation holes and waterproof and breathable membranes, the gas in the box body 1 can enter the seedbed through the ventilation holes and the waterproof and breathable membranes, effectively improving the ventilation of the flower cultivation substrate in the seedbed.

[0024] In the present invention, a seedbed composed of a first support net and a plurality of funnel parts is fixedly arranged in the upper space of the box body, a plurality of ventilation holes are arranged at intervals on the side wall of the funnel part, and a breathable waterproof membrane is arranged on each ventilation hole, so that after the redundant liquid in the flower cultivation substrate is preliminarily collected by the funnel part and flows into the return water tank through the return water pipe, the gas in the box body can enter the seedbed through the ventilation holes and the waterproof breathable membrane, effectively improving the ventilation of the flower cultivation substrate in the seedbed.

[0025] In another embodiment, as Figure 2 , Figure 3 shown, openings are provided on two opposite side walls of the box body 1, the openings are arranged opposite to the funnel parts 4, and a plurality of rotating plates 14 are arranged at intervals in the openings, and the rotating plates 14 are driven to rotate by a driving assembly to open or close the openings.

[0026] In this embodiment, by providing an opening at the position on the side wall of the box body opposite to the funnel part and arranging a plurality of rotating plates driven to rotate by a driving assembly in the opening, under normal circumstances, the rotating plates do not move and the opening is in a closed state to avoid impurities such as flying insects from entering the box body to the greatest extent. When the ventilation of the flower cultivation substrate is insufficient and the flowers show problems such as suffocated roots and yellow leaves, the driving assembly is started, and the rotating plates are driven to rotate by the driving assembly to increase the flow rate of the air inside the box body and promote the upward flow of air through the ventilation holes and the waterproof breathable membrane to further improve the ventilation of the flower cultivation substrate in the seedbed. Of course, in order to prevent problems such as suffocated roots and yellow leaves of the flowers, the driving assembly can also be started periodically.

[0027] In another embodiment, as Figures 1-4 shown, mounting grooves 15 are fixedly arranged on the upper and lower sides of the opening respectively, the upper and lower ends of the rotating plate 14 are respectively rotatably connected to the mounting grooves 15 through connecting columns 16, and the adjacent connecting columns 16 at the lower end are connected by chain drive; the driving assembly includes a driving shaft 17 which is rotatably arranged on the two opposite side walls and is located on the lower side of the drain pipe 12; a driving ring 18 which is coaxially and fixedly sleeved on the driving shaft 17 and is on the same vertical plane as the drain pipe 12, and a plurality of grooves 19 are arranged at intervals along the circumferential direction on the outer ring surface of the driving ring 18; two transmission shafts 20 which are respectively arranged above the two ends of the driving shaft 17, each transmission shaft 20 is vertically arranged, and the lower end of the transmission shaft 20 is connected to the end of the driving shaft 17 by bevel gear drive, and the upper end extends into the mounting groove 15 and is connected to the adjacent connecting column 16 by circular gear or chain drive.

A plurality of grooves are arranged on the circumference of the driving ring. The driving shaft, the transmission shaft and the connecting column are in transmission connection. When the water in the water return tank drains through the drain pipe, the driving ring can rotate under the action of the water flow, thereby driving the driving shaft to rotate. Then, through the transmission of the transmission shaft and the connecting column, the rotating plate fixed on the connecting column is driven to rotate, thereby realizing the rotation of the rotating plate. The water in the water return tank can be used to drive the rotating plate to rotate, which is green and environmentally friendly and will not cause pollution to the liquid in the box body.

[0029] In another embodiment, as Figure 1 shown, a second support net is fixedly arranged on the air vent, and the waterproof breathable film 5 is fixedly arranged on the second support net.

[0033] In another embodiment, a sewage pipe communicating with the outside is arranged at the bottom of the water return tank 9, and a fourth one-way valve is arranged on the sewage pipe.

[0034] In this embodiment, a sewage pipe and a fourth one-way valve are arranged at the bottom of the water return tank, so that the fourth one-way valve can be opened as needed to discharge the sewage in the water return tank through the sewage pipe, facilitating the cleaning of the water return tank.
