[0002] In the field of agricultural and forestry planting, especially in elevated cultivation systems, drip irrigation systems are widely used due to their water-saving and precise characteristics; however, most existing elevated cultivation systems are only equipped with drip irrigation functions, lack special drainage facilities, and rely solely on simple drainage holes opened at the bottom of the cultivation trough for natural drainage. This design has obvious defects in actual application: the drainage holes of the cultivation trough lack effective anti-blocking measures. During long-term use, impurities such as mud, plant root residues and fertilizer crystals are very likely to accumulate in the drainage holes, causing blockage of the drainage channels; especially in the rainy season or centralized irrigation, the blocked drainage holes will make it impossible for the accumulated water in the cultivation trough to be discharged in time, which not only affects the respiration of the crop roots, but may also cause root rot, diseases and other problems, seriously affecting crop yield and quality.

[0016] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application.

[0017] Example 1 See also Figure 1 The drought-resistant and waterlogging-draining drip irrigation system for agricultural and forestry planting is applied to a cultivation rack 1. The cultivation rack 1 includes a rack and a cultivation trough provided on the rack. The interior of the cultivation trough is used for planting plants. The drought-resistant and waterlogging-draining drip irrigation system includes a drip irrigation component and a drainage component. See also Figure 1 The drip irrigation assembly includes a liquid supply device 2 (the liquid supply device 2 can be composed of a liquid reservoir and a delivery pump, the inlet of the delivery pump is connected to the liquid reservoir, and the delivery pump works to deliver the water inside the liquid reservoir to the drip tube 3) and a drip tube 3, the drip tube 3 is connected to the liquid outlet of the liquid supply device 2, and the drip tube 3 is arranged above the cultivation trough; See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The drainage component includes a collection trough 4 and an anti-blocking component 5 provided on the collection trough 4; the collection trough 4 is located below the cultivation trough, the anti-blocking component 5 includes a support plate 502 and a first filter layer 504 and a second filter layer 505 provided on the support plate 502, the first filter layer 504 is located on the outside of the second filter layer 505 and the two are arranged at intervals (the first filter layer 504 and the second filter layer 505 are arranged in concentric circles), the support plate 502, the first filter layer 504 and the second filter layer 505 are located inside the cultivation trough, the support plate 502 is located above the first filter layer 504 and the second filter layer 505, and the second filter layer 505 covers the drainage hole of the cultivation trough.

[0018] The specific steps of the drip irrigation method for drought resistance and waterlogging drainage in agriculture and forestry are as follows: First, the delivery pump of the liquid supply device 2 delivers the water in the liquid reservoir to the drip tube 3, so that the water is discharged through the liquid outlet of the drip tube 3 and irrigates the plants in the cultivation tank; Second, excess water in the cultivation trough gathers at the bottom of the inner cavity of the cultivation trough, and after being filtered by the first filter layer 504 and the second filter layer 505, falls into the collection trough 4 through the drainage hole.

[0019] In this embodiment, as a further optimization solution, please refer to Figure 4 The second filter layer 505 is a filter screen, and the first filter layer 504 is an inorganic matrix filter layer. The inorganic matrix filter layer is composed of a gauze and an inorganic matrix. The inorganic matrix is ​​wrapped by the gauze. The inorganic matrix can be perlite or vermiculite. The inorganic matrix filter layer has good air permeability and drainage, ensuring that excess water in the cultivation trough can pass through the inorganic matrix filter layer, promoting the discharge of excess water, and the inorganic matrix filter layer can prevent impurities from approaching the second filter layer 505, reducing the chance of the second filter layer 505 being blocked.

[0020] In this embodiment, as a further optimization solution, please refer to Figure 3 and Figure 4 A support block 503 is provided at the bottom of the support plate 502, and the support block 503 is in contact with the bottom of the inner cavity of the cultivation trough to support the support plate 502, reduce the pressure on the first filter layer 504 and the second filter layer 505, and avoid deformation of the two; the support block 503 is in contact with the outer wall of the second filter layer 505, and a support rod 501 is rotatably provided on the support plate 502, and the support rod 501 is connected to the second filter layer 505; by rotating the support rod 501, the second filter layer 505 is rotated to contact the support block 503, which can scrape off impurities attached to the outside of the second filter layer 505 and reduce the chance of the second filter layer 505 being blocked.

[0021] It should be noted that the bottom end of the support rod 501 passes through the drainage hole of the cultivation trough and is rotatably connected to the bottom of the inner cavity of the collecting trough 4. There is a protrusion on the side wall of the support rod 501, which is in contact with the drainage hole; the water passing through the drainage hole will contact the protrusion and be guided to the inside of the collecting trough 4 along the support rod 501, accelerating the discharge of water from the cultivation trough. At the same time, by guiding the water through the support rod 501, the chance of water splashing when falling into the collecting trough 4 can be reduced.

[0022] Example 2 As a further optimization solution of Example 1, please refer to Figure 1 、 Figure 2 and Figure 3 A first drain outlet is provided at the bottom of the inner cavity of the collecting tank 4, and the first drain outlet is connected to the liquid supply device 2 through the first return pipe 6. A filter element 10 (such as a filter net) is provided in the collecting tank 4, and the filter element 10 is used to filter the water entering the first return pipe 6; after the water inside the collecting tank 4 is filtered by the filter element 10, it flows into the liquid supply device 2 through the first drain outlet and the first return pipe 6 for recycling.

[0023] It should be noted that the bottom of the inner cavity of the collecting tank 4 is inclined toward the first drain port, so as to facilitate the discharge of water inside the collecting tank 4 .

[0024] In this embodiment, as a further optimization solution, please refer to Figure 1 、 Figure 2 and Figure 3 , a second drain port is provided at the bottom of the inner cavity of the collecting tank 4, the second drain port and the first drain port are respectively located on both sides of the filter element 10, a floating plate 12 is provided in the inner cavity of the collecting tank 4 for sliding, the floating plate 12 is used to block the second drain port, and the second drain port is connected to the collecting box 8 through the second reflux pipe 7; on the left side of the inner cavity of the collecting tank 4 (such as Figure 3 As shown, when the water level in the area (where the water has not passed through the filter element 10) rises, the float 12 will move upward under the action of buoyancy, opening the second drain port, so that the water on the left side of the inner cavity of the collection tank 4 is directly discharged from the second drain port and falls into the interior of the collection box 8, thereby preventing the water level inside the collection tank 4 from being too high and overflowing.

[0025] It should be noted that a filtering device (such as a filter) is installed inside the collection box 8 to filter the water inside the collection box 8, and then the filtered water is introduced into the liquid supply device 2 for reuse.

[0026] In this embodiment, as a further optimization solution, please refer to Figure 3A liquid level sensor 11 is provided in the collecting tank 4. The liquid level sensor 11 and the floating plate 12 are located on the same side of the filter element 10. A pump 16 is provided on the collecting tank 4. The inlet of the pump 16 is connected to the collecting tank 4 through a pipe, and the outlet of the pump 16 is connected to the second return pipe 7 through a pipe; when the liquid level sensor 11 detects that the internal water level of the collecting tank 4 is higher than the threshold value, the pump 16 is started to extract the water inside the collecting tank 4 and accelerate the discharge to avoid overflow of the collecting tank 4 and prevent the overflowed water from flowing into the cultivation tank below.

[0027] It should be noted that the irrigation system includes a controller (such as a PLC controller) for receiving information from the liquid level sensor 11 and controlling the pump 16 to start when the water level is higher than a threshold.

[0028] In this embodiment, as a further optimization solution, please refer to Figure 1 and Figure 5 The cultivation rack 1 is provided with a driving member 13 (such as an electric telescopic rod), and a shielding plate 9 is provided on the movable end of the driving member 13; when the liquid level sensor 11 detects that the internal water level of the collecting tank 4 is higher than the threshold value, the driving member 13 is controlled by the controller to drive the shielding plate 9 to move above the cultivation tank to shield the cultivation tank and prevent rainwater from falling into the cultivation tank, thereby achieving a flood prevention effect. The shielding plate 9 is suitable for situations where rainfall is heavy.

[0029] In this embodiment, as a further optimization solution, please refer to Figure 5 and Figure 6 The cultivation rack 1 is provided with a telescopic member 14 (such as a telescopic rod, specifically including a telescopic mother rod and a telescopic child rod slidably inserted in the telescopic mother rod), the moving end of the driving member 13 is connected to the fixed end of the telescopic member 14, and the shielding plate 9 is hinged on the moving end of the telescopic member 14. A guide groove 15 is provided on the side wall of the cultivation rack 1, and a guide block is provided on the moving end of the telescopic member 14. The guide block is inserted in the guide groove 15, and the guide groove 15 is inclined upward along the direction in which the shielding plate 9 moves to block the cultivation groove; when the driving member 13 drives the shielding plate 9 to move above the cultivation groove, the driving member 13 will move with the telescopic member 14, so that the guide block slides in the guide groove 15. Guided by the guide groove 15, the telescopic member 14 will extend, so that the shielding plate 9 moves upward away from the cultivation groove, so as to tilt downward with the side of the shielding plate 9 close to the cultivation groove, so as to guide rainwater so that rainwater will not gather above the shielding plate 9.

[0030] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention.
