[0027] like Figure 3 and Figure 5As shown, a vertically extending humidifying pipe 8 is fixedly installed on the top of the partition 6. A plurality of humidifying pipes 8 are evenly spaced along the length direction of the planting trough 5, and a plurality of water-permeable holes 9 are evenly distributed on the side walls of the humidifying pipes 8 immersed in the soil 7; a water injection pipe 10 corresponding to the humidifying pipes 8 is also fixedly installed on the top of the partition 6. The water injection pipe 10 extends upward into the humidifying pipe 8, and a plurality of water injection holes 11 are evenly distributed on the side walls of the water injection pipe 10.

[0028] In this embodiment, the partition 6 is provided with a plurality of mounting holes 12 which are vertically penetrated, and the plurality of mounting holes 12 are evenly spaced along the length direction of the planting groove 5, and a joint 13 is fixedly installed in the mounting hole 12; Figure 5 and Figure 6 As shown, the joint 13 is provided with a cylindrical first threaded portion 14, a cylindrical second threaded portion 15 is coaxially provided at the lower end of the first threaded portion 14, a cylindrical plug-in portion 16 is coaxially provided at the lower end of the second threaded portion 15, the diameters of the first threaded portion 14, the second threaded portion 15 and the plug-in portion 16 decrease successively, a circular limiting plate 17 is also provided between the first threaded portion 14 and the second threaded portion 15, a flow channel 18 is provided in the joint 13, which passes through the first threaded portion 14 from the lower end of the plug-in portion 16 upward; the second threaded portion 15 is penetrated into the mounting hole 12, the limiting plate 17 abuts against the top of the partition 6 and the diameter of the limiting plate 17 is larger than the diameter of the mounting hole 12, and a fastening nut 19 is screwed on the second threaded portion 15 located below the partition 6, thereby fixing the joint 13.

[0029] The humidifying tube 8 corresponds to the joint 13 one by one, the upper end of the humidifying tube 8 is closed and the lower end is open, and the lower end of the humidifying tube 8 is screwed on the outer side of the upper end of the first threaded portion 14; a circular mounting groove 20 is provided on the top of the first threaded portion 14, and the upper end of the flow channel 18 is connected to the bottom of the mounting groove 20, the upper end of the water injection pipe 10 is closed and the lower end is open, the lower end of the water injection pipe 10 is screwed into the mounting groove 20 and the lower end of the water injection pipe 10 is connected to the upper end of the flow channel 18.

[0030] like Figure 2 and Figure 3 As shown, a sandwich 21 is provided between the partition 6 and the bottom wall of the planting trough 5, and a water supply branch pipe 22 is provided in the sandwich 21. One end of the water supply branch pipe 22 is closed and fixedly installed on the inner wall of the planting trough 5 by bolts, and the other end of the water supply branch pipe 22 extends to the outside of the planting trough 5, and the ends of multiple water supply branch pipes extending outside the planting trough 5 are all connected to the same main water supply pipe 23, the main water supply pipe 23 is connected to the water supply tank 24, and a water pump 25 is provided on the main water supply pipe 23. Flexible hoses 26 are respectively connected between the water supply branch pipe 22 and multiple joints 13, and connecting pipes 27 corresponding to the joints 13 are provided on the water supply branch pipe 22, and one end of the flexible hose 26 is sleeved on the connecting pipe 27, and the other end is sleeved on the plug-in portion 16 at the lower end of the joint 13.

[0031] When watering, driven by the water pump 25, the water in the water supply branch pipe 22 enters the water injection pipe 10 through the hose 26, and then is evenly poured into the humidification pipe 8 through the multiple water injection holes 11 on the side wall of the water injection pipe 10, and finally is poured into the soil layers of different depths through the multiple water permeable holes 9 on the side wall of the humidification pipe 8, thereby improving the irrigation efficiency and achieving the purpose of uniform watering and saving water resources.

[0032] Since the water irrigated to the upper layer of the soil will continue to penetrate into the lower layer of the soil over time, in order to prevent the lower layer of the soil from accumulating a large amount of water, the aperture of the water permeable hole 9 located below is smaller than the aperture of the water permeable hole 9 located above, so that during the process of humidifying the soil through the humidification pipe 8, the soil in the upper layer obtains more water and the soil in the lower layer obtains less water.

[0033] like Figure 5 As shown, in order to prevent soil from entering the humidifying tube 8 through the water permeable holes 9, a filter screen 28 is provided in the humidifying tube 8 to cover the water permeable holes 9.

When one of the humidity sensors 30 detects that the humidity of the soil is lower than the preset value, the water pump 25 is started, and the solenoid valve 31 corresponding to the humidification tube 8 adjacent to the humidity sensor 30 is opened, so as to automatically irrigate the soil in a targeted manner. On the contrary, when all the humidity sensors 30 detect that the humidity of the soil is higher than the preset value, the water pump 25 is turned off, and all the solenoid valves 31 are closed, and irrigation is stopped.

[0036] The side wall of the planting trough 5 is provided with a drainage hole 32 communicating with the inner cavity of the planting trough 5 located above the partition 6; the bottoms of one end of the plurality of trays 4 are respectively connected to the same vertically extending main water return pipe 34 through the water return branch pipe 33, and the lower end of the main water return pipe 34 is connected to the water storage tank 35. The excess water in the planting trough 5 can be discharged through the drainage hole 32 to prevent a large amount of water from accumulating in the planting trough 5 located above the partition 6 and causing the root of the crop to rot; the excess water is discharged through the drainage hole 32 and then gathered in the tray 4, and then returned to the water storage tank 35 through the water return branch pipe 33 and the main water return pipe 34, so that the water can be recycled.
