Description

Technical Field

[0001] The present application relates to the field of gardening cultivation and maintenance technology, and in particular to a cultivation and maintenance device and method for planting trees and shrubs in poorly drained soil. Background Art

[0002] When planting trees and shrubs, in order to facilitate irrigation of the trees and shrubs, pipes are usually laid on the ground with water outlets for irrigation of the trees and shrubs. However, in soil with poor drainage, it is difficult for water to penetrate into the ground, resulting in water accumulation on the surface. The soil around the roots of trees and shrubs has less moisture, thus affecting their growth.

[0003] At present, when planting trees and shrubs on poorly drained soil, the common practice is to directly replace the soil that is not suitable for planting by manual or mechanical means, or to mix high-quality soil in a certain proportion to improve the soil environment. Although these methods are direct and effective, they are costly and complicated to operate, which limits their use in large-scale projects. Summary of the invention

[0004] In order to facilitate irrigation of the soil around the root systems of trees and shrubs, the present application provides a cultivation and maintenance device and method for planting trees and shrubs in poorly drained soil.

[0005] The present application provides a cultivation and maintenance device and method for planting trees and shrubs in poorly drained soil, which adopts the following technical solutions: A cultivation and maintenance device for planting trees and shrubs in soil with poor drainage, wherein a plurality of second shunt pipes are fixedly connected to the body of a first shunt pipe, a planting area is formed on the ground between two adjacent second shunt pipes, a plurality of irrigation pipes are connected to both sides of the second shunt pipe, the first shunt pipe, the second shunt pipe and the irrigation pipe are all buried under the ground, the irrigation pipes on both sides of the second shunt pipe are arranged away from each other and inclined from top to bottom, a plurality of water outlet holes are opened on the sides of the pipe bodies of the irrigation pipes on both sides of the second shunt pipe away from each other, the plurality of water outlet holes are arranged at intervals along the length direction of the irrigation pipe, and a first non-woven fabric is installed on the outer wall of the irrigation pipe.

[0006] By adopting the above technical solution, trees and shrubs are planted in the planting area, water enters the first shunt pipe, and the water inside the first shunt pipe enters the second shunt pipe. The water inside the second shunt pipe enters the irrigation pipe, and the water inside the irrigation pipe is sprayed out from the water outlet. Since the irrigation pipes on both sides of the second shunt pipe are arranged away from each other from top to bottom, the water outlets are arranged at intervals along the length direction of the irrigation pipe, so that water leaks from multiple positions underground from top to bottom to the soil around the root system of trees and shrubs, thereby facilitating irrigation of the soil around the root system of trees and shrubs.

[0007] The first non-woven fabric plays a role in shielding mud and sand, thereby reducing the occurrence of mud and sand entering the interior of the irrigation pipe from the water outlet.

[0008] Optionally, a hose is fixedly installed on one end of the irrigation pipe close to the second diversion pipe, a mounting ring is fixedly installed on one end of the hose away from the irrigation pipe, a plurality of mounting pipes are fixedly installed on the body of the second diversion pipe, and the mounting ring is threadedly sleeved on the mounting pipe.

[0009] By adopting the above technical solution, when the first shunt pipe, the second shunt pipe and the irrigation pipe are buried underground, the first shunt pipe and the second shunt pipe are firstly placed in a groove dug on the ground, and then the irrigation pipe is placed in a groove. Then the installation ring is screwed into the installation pipe to connect the irrigation pipe with the second shunt pipe. The detachable design of the irrigation pipe and the second shunt pipe facilitates replacement of the irrigation pipe after it is damaged.

[0010] Optionally, a first gravel layer is installed on the side of the irrigation pipes located on both sides of the second diversion pipe that are away from each other.

[0011] By adopting the above technical solution, when it rains, the water on the ground slowly seeps downward into the ground. However, the longer the rain lasts, the more rainwater seeps downward, and the water content in the soil increases, so that the roots of trees and shrubs are soaked in water. The first gravel layer has good drainage, so that after the water in the soil with poor drainage seeps into the first gravel layer, the water gathers in the first gravel layer. Afterwards, the water in the first gravel layer enters the irrigation pipe from the water outlet, and some water is retained through the irrigation pipe, thereby reducing the situation where the roots of trees and shrubs are soaked by rainwater. At the same time, the first gravel layer plays a filtering role, thereby reducing the situation where mud and sand block the water outlet.

[0012] Optionally, a first baffle is fixedly installed on the inner wall of one end of the irrigation pipe away from the second diversion pipe, the first baffle is provided with a plurality of first drainage outlets, a second baffle is provided on a side of the first baffle away from the second diversion pipe, the second baffle is provided with a plurality of second drainage outlets, a rotating rod is coaxially fixedly installed on the second baffle, the rotating rod rotates through the first baffle, a driving mechanism is installed on the rotating rod, the driving mechanism is used to drive the rotating rod to rotate, and the rotating rod is used to drive the second baffle to rotate so that the first drainage outlet and the second drainage outlet are staggered or overlapped with each other.

[0013] By adopting the above technical solution, when it rains, if the soil moisture content around the roots of trees and shrubs is high, water enters the irrigation pipe from the water outlet. The driving mechanism drives the rotating rod to rotate, and the rotating rod drives the second shielding plate to rotate to align the first drainage port and the second drainage port. After that, the water inside the irrigation pipe is discharged from the first drainage port and the second drainage port and enters the soil below the roots of trees and shrubs, thereby reducing the moisture content of the soil around the roots of trees and shrubs, and further reducing the situation where the roots of trees and shrubs are soaked by rainwater. The soil moisture content around the roots of trees and shrubs is reduced, which facilitates the rainwater on the ground to seep downward, and then facilitates the discharge of rainwater on the ground.

[0014] Optionally, the driving mechanism includes a first floating block, a sliding rod and a spring. The first floating block is located on a side of the first baffle plate away from the second baffle plate. The first floating block is provided with a sliding hole for the rotating rod to pass through. The sliding rod is fixedly installed on the inner wall of the sliding hole. The rod body of the rotating rod is provided with a sliding groove for the sliding rod to slide. The sliding groove is inclined. The peripheral side of the first floating block is key-connected to the inner wall of the irrigation pipe to limit the rotation of the first floating block. The spring is fixedly installed between the first floating block and the first baffle plate.

[0015] By adopting the above technical solution, when water enters the irrigation pipe from the water outlet, the amount of water is small, the spring drives the first float to move toward the first shielding plate, and the first float drives the slide bar to slide from the top to the bottom of the slide groove. Since the first float is key-connected to the inner wall of the irrigation pipe and cannot rotate, when the slide bar slides from the top to the bottom of the slide groove, the rotating rod rotates to align the first drain port and the second drain port, so that when it rains, the water in the soil enters the irrigation pipe, and the water inside the irrigation pipe is discharged from the first drain port and the second drain port.

[0016] When the solenoid valve is opened to allow water to enter the soil around the roots of trees and shrubs from the water outlet, a large amount of water enters the irrigation pipe, and the water inside the irrigation pipe covers the first float. The first float moves away from the first baffle plate due to the buoyancy, and the first float drives the slide bar to slide from the bottom end of the slide groove to the top end. Since the first float is keyed to the inner wall of the irrigation pipe and cannot rotate, when the slide bar slides from the bottom end of the slide groove to the top end, the rotating rod rotates to stagger the first drain outlet and the second drain outlet, thereby reducing the situation in which the water inside the irrigation pipe is discharged from the first drain outlet and the second drain outlet during irrigation.

[0017] Optionally, a drain pipe is fixedly installed at one end of the irrigation pipe away from the second diversion pipe, the interior of the drain pipe is filled with a second sand and gravel layer, a plurality of drainage holes are opened on the peripheral side wall of the drain pipe, and a mesh plate is fixedly installed at one end of the drain pipe away from the irrigation pipe.

[0018] By adopting the above technical solution, the drain pipe is used to extend the irrigation pipe. When water is discharged from the first drain outlet and the second drain outlet, the drain pipe guides the water to be discharged deep underground, thereby reducing the occurrence of rainwater soaking the roots of trees and shrubs. The second gravel layer and the mesh plate play a shielding role, thereby reducing the occurrence of mud and sand entering the drain pipe from the drain holes and the bottom of the drain pipe. At the same time, the second gravel layer is used to reduce the space inside the drain pipe, allowing the water inside the drain pipe to be discharged from multiple drain holes, thereby speeding up the speed of water being discharged from the drain pipe. Multiple drainage holes are located in different positions, so that it is convenient for water to be dispersed and discharged into the soil, and then it is convenient for water to infiltrate into the ground.

[0019] Optionally, a plurality of water inlet pipes are fixedly installed on the top side of the tube body of the second diversion pipe, the water inlet pipes are vertically arranged, a blocking block is fixedly installed on the top of the water inlet pipe, a second non-woven fabric is fixedly installed on the top side of the blocking block, a plurality of first water inlet holes are opened in the blocking block, the top side of the blocking block is flush with the ground, a blocking assembly is arranged inside the water inlet pipe, and the blocking assembly is used to block the first water inlet holes.

[0020] By adopting the above technical solution, when water accumulates on the ground during rainy days, the shielding component opens the first water inlet hole. Rainwater enters the water inlet pipe from the first water inlet hole, and then the water inside the water inlet pipe enters the irrigation pipe from the second diversion pipe, and the water inside the irrigation pipe is discharged from the first drainage port and the second drainage port, thereby reducing the occurrence of water accumulation on the ground.

[0021] When the solenoid valve is opened to irrigate the soil around the roots of trees and shrubs, the shielding component shields the first water inlet hole, thereby reducing the water in the second diversion pipe from entering the water inlet pipe, and the water is then discharged from the first water inlet hole.

[0022] Optionally, the shielding assembly includes a second float, a guide rod and a blocking rod, one end of the guide rod is fixedly connected to a side of the shielding block close to the water inlet pipe, the second float is located inside the water inlet pipe, the guide rod slides through the second float, the second float is provided with a plurality of second water inlet holes, there are multiple blocking rods, the blocking rods are arranged in a one-to-one correspondence with the first water inlet holes, one end of the blocking rod is fixedly connected to a side of the second float close to the blocking block, and the other end of the blocking rod is used to enter and exit the first water inlet hole.

[0023] By adopting the above technical solution, when the electromagnetic valve is opened to irrigate the soil around the roots of trees and shrubs, the water inside the second diversion pipe will enter the water inlet pipe. As the water level inside the water inlet pipe increases, the second float moves upward, so that the blocking rod is inserted into the first water inlet hole, thereby facilitating the blocking of the first water inlet hole.

[0024] When the ground water needs to be drained, the second floating block moves downward under the force of gravity, so that the blocking rod is pulled out of the first water inlet hole. Then the ground water enters the water inlet pipe from the first water inlet hole and the second water inlet hole, so that the first water inlet hole is opened easily.

[0025] Optionally, it also includes a solenoid valve, a soil moisture sensor and a controller, the solenoid valve is installed on the first shunt pipe, the soil moisture sensor is inserted into the planting area, the soil moisture sensor is used to generate a humidity signal according to the humidity of the soil and send it to the controller, and the controller opens and closes the solenoid valve according to the humidity signal.

[0026] By adopting the above technical solution, the soil moisture sensor detects the soil moisture, and when the soil moisture is lower than the preset threshold, the controller opens the solenoid valve. When the soil moisture is higher than the preset threshold, the controller closes the solenoid valve, thereby facilitating automatic irrigation of the soil around the roots of trees and shrubs.

[0027] A method for cultivating and maintaining trees and shrubs in poorly drained soil, comprising the following steps: According to the depth of the tree and shrub root system underground, the first shunt pipe, the second shunt pipe and the irrigation pipe are buried underground, and the bottom end of the irrigation pipe is located at a depth lower than the depth of the tree and shrub root system; Plant trees and shrubs in the planting area; When the solenoid valve is turned on, water flows through the first shunt pipe, the second shunt pipe and the irrigation pipe in sequence and then is sprayed out from the irrigation hole to moisten the soil around the roots of trees and shrubs.

[0028] By adopting the above technical solution, the irrigation pipe is located at the root system of the trees and shrubs, and water is sprayed from the water outlet to the soil around the root system of the trees and shrubs, thereby irrigating the soil around the root system of the trees and shrubs conveniently.

[0029] In summary, the present application includes at least one of the following beneficial technical effects: 1. Water is sent to the second shunt pipe through the first shunt pipe, and then the water inside the second shunt pipe enters the irrigation pipe, and the water inside the irrigation pipe is sprayed out from the water outlet. Since the irrigation pipes on both sides of the second shunt pipe are arranged away from each other from top to bottom, the water outlets are arranged at intervals along the length direction of the irrigation pipe, so that water is sprayed from multiple positions from top to bottom to the soil around the roots of trees and shrubs, thereby facilitating irrigation of the soil around the roots of trees and shrubs; 2. When rainwater gathers on the ground, the shielding component opens the first water inlet hole, so that the rainwater on the ground can enter the water inlet pipe from the first water inlet hole, and then the water rushes into the water pipe and enters the second diversion pipe. The water inside the second diversion pipe enters the irrigation pipe and is discharged from a position lower than the root system of trees and shrubs, thereby reducing water accumulation on the ground.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-7 This application is described in further detail.

[0033] The embodiments of the present application disclose a cultivation and maintenance device and method for planting trees and shrubs in poorly drained soil.

[0034] Reference Figure 1 , Figure 2 , Figure 3 A cultivation and maintenance device for planting trees and shrubs in poorly drained soil includes a first shunt pipe 3. Both ends of the first shunt pipe 3 are blocked, and the pipe body of the first shunt pipe 3 is connected to a water source. In another embodiment, one end of the first shunt pipe 3 is used to connect to the water source, and the other end of the first shunt pipe 3 is blocked.

[0035] Reference Figure 2 , Figure 3 The first shunt pipe 3 is fixedly connected to a plurality of second shunt pipes 4. The first shunt pipe 3 and the second shunt pipe 4 are both arranged horizontally and perpendicular to each other. The second shunt pipe 4 is sealed at one end away from the first shunt pipe 3. A plurality of mounting pipes 5 are fixedly installed on both sides of the second shunt pipe 4. The mounting pipe 5 is provided with an irrigation pipe 6, and a hose 7 is fixedly installed at one end of the irrigation pipe 6. A mounting ring 8 is fixedly installed at one end of the hose 7 away from the irrigation pipe 6, and the mounting ring 8 is threadedly sleeved on the mounting pipe 5.

[0036] The mounting ring 8 is screwed into the mounting pipe 5, so as to facilitate the installation of the irrigation pipe 6 on the second diverter pipe 4. After the irrigation pipe 6 is damaged, the mounting ring 8 is screwed out from the mounting pipe 5, so as to facilitate the removal of the irrigation pipe 6 from the second diverter pipe 4 for replacement.

[0037] Reference Figure 1 , the first shunt pipe 3, the second shunt pipe 4 and the irrigation pipe 6 are all buried underground. When the first shunt pipe 3, the second shunt pipe 4 and the irrigation pipe 6 are buried underground, it is generally necessary to dig a groove on the ground for placing the first shunt pipe 3, the second shunt pipe 4 and the irrigation pipe 6, and then put the first shunt pipe 3, the second shunt pipe 4 and the irrigation pipe 6 into the groove dug on the ground. Through the detachable connection between the second shunt pipe 4 and the irrigation pipe 6 and the flexibility of the hose 7, the accuracy of the position of the groove dug for the second shunt pipe 4 and the irrigation pipe 6 is reduced, thereby facilitating the burial of the first shunt pipe 3, the second shunt pipe 4 and the irrigation pipe 6.

[0038] Reference Figure 1 , Figure 3 The ground between two adjacent second shunt pipes 4 forms a planting area 9, and the planting area 9 is used to plant trees and shrubs. The irrigation pipes 6 located on both sides of the second shunt pipe 4 are arranged away from each other from top to bottom and are inclined. The irrigation pipes 6 located on both sides of the second shunt pipe 4 are provided with a plurality of water outlet holes 10 on the side away from each other, and the plurality of water outlet holes 10 are arranged at intervals along the length direction of the irrigation pipe 6.

[0039] The water from the water source enters the first shunt pipe 3, and the water inside the first shunt pipe 3 enters the second shunt pipe 4. The water inside the second shunt pipe 4 enters the irrigation pipe 6, and the water inside the irrigation pipe 6 is sprayed out from the water outlet 10. The water outlets 10 are located at different positions of the tree and shrub root system from top to bottom, so as to spray water at different positions of the soil around the tree and shrub root system, thereby facilitating irrigation of the soil around the tree and shrub root system.

[0040] If it is necessary to irrigate the trees and shrubs with nutrient solution, the nutrient solution is irrigated by replacing the water source. In another embodiment, a nutrient tank for storing the nutrient solution can be provided, and the nutrient tank is connected to the first diverter pipe 3 through a valve and a pipeline, so as to facilitate the selection of water or nutrient solution for irrigating the trees and shrubs.

[0041] Reference Figure 1, also includes a solenoid valve 1, a soil moisture sensor 11 and a controller 12, the solenoid valve 1 is fixedly installed on the first shunt pipe 3, the controller 12 is fixedly installed on the solenoid valve 1, and the soil moisture sensor 11 is inserted into the planting area 9. The soil moisture sensor 11 detects the humidity of the soil, generates a humidity signal and sends it to the controller 12. When the humidity signal is less than a preset threshold, the controller 12 opens the solenoid valve 1 to irrigate the soil around the roots of trees and shrubs. When the humidity signal is greater than a preset threshold, the controller 12 closes the solenoid valve 1 to stop irrigating the soil around the roots of trees and shrubs. The opening and closing of the solenoid valve 1 is controlled by the controller 12, so as to facilitate automatic irrigation when the soil around the roots of trees and shrubs is short of water.

[0042] Reference Figure 1 , Figure 3 The outer wall of the irrigation pipe 6 is provided with a first non-woven fabric 13, and the pipe bodies of the irrigation pipes 6 on both sides of the second diversion pipe 4 are provided with a first gravel layer 15 on the side away from each other. The first non-woven fabric 13 and the first gravel layer 15 play a filtering role, thereby reducing the amount of sediment entering the irrigation pipe 6 from the water outlet 10.

[0043] On rainy days, the soil has poor drainage, and rainwater will gather on the ground to form waterlogging, with less rainwater seeping downward. If the rainy day lasts for a long time, as the rainwater seeps downward, the water content of the soil around the roots of trees and shrubs increases, so that the roots of trees and shrubs are soaked in water, which in turn affects the growth of trees and shrubs. The first gravel layer 15 has good drainage, and the water in the soil will seep into the first gravel layer 15. Afterwards, the water in the first gravel layer 15 enters the irrigation pipe 6 from the water outlet 10, thereby reducing the water content of the soil around the roots of trees and shrubs, thereby facilitating the growth of trees and shrubs.

[0044] Reference Figure 4 , Figure 5 , Figure 6 A first shielding plate 17 is fixedly installed on the inner wall of one end of the irrigation pipe 6 away from the second diversion pipe 4, and the first shielding plate 17 is provided with a plurality of first drainage ports 19. A second shielding plate 18 is provided on one side of the first shielding plate 17 away from the second diversion pipe 4, and the second shielding plate 18 is provided with a plurality of second drainage ports 20, and the first drainage ports 19 and the second drainage ports 20 are arranged one by one. A rotating rod 21 is coaxially fixedly installed on the second shielding plate 18, and the rotating rod 21 rotates through the first shielding plate 17, and the rotating rod 21 has a limiter for limiting the sliding of the rotating rod 21 along the length direction.

[0045] Reference Figure 5 , Figure 6The rotating rod 21 is provided with a driving mechanism 22, and the driving mechanism 22 includes a first floating block 221, a sliding rod 222 and a spring 223. The first floating block 221 is located on the side of the first shielding plate 17 away from the second shielding plate 18, and the first floating block 221 is provided with a sliding hole 23 for the rotating rod 21 to pass through. The sliding rod 222 is fixedly installed on the inner side wall of the sliding hole 23, and the rod body of the rotating rod 21 is provided with a sliding groove 24 for the sliding rod 222 to slide, and the sliding groove 24 is inclined. The peripheral side of the first floating block 221 is key-connected with the inner wall of the irrigation pipe 6 to limit the rotation of the first floating block 221, and the spring 223 is fixedly installed between the first floating block 221 and the first shielding plate 17.

[0046] When the solenoid valve 1 is opened to irrigate the soil around the roots of trees and shrubs, a large amount of water enters the irrigation pipe 6. After the buoyancy of the water inside the irrigation pipe 6 on the first float 221 is greater than the tension of the spring 223, the first float 221 moves away from the first baffle 17, so that the slide bar 222 moves from the bottom end to the top end of the slide groove 24. Since the first float 221 is keyed to the inner wall of the irrigation pipe 6, the first float 221 cannot rotate, so that the rotating rod 21 drives the second baffle 18 to rotate so that the first drain port 19 and the second drain port 20 are staggered, thereby facilitating the blocking of the bottom end of the irrigation pipe 6. By blocking the bottom end of the irrigation pipe 6, it is convenient for the water inside the irrigation pipe 6 to spray out from the water outlet 10 to irrigate the soil around the roots of trees and shrubs.

[0047] After closing the solenoid valve 1, the water inside the irrigation pipe 6 is gradually discharged from the water outlet 10, and the water level inside the irrigation pipe 6 drops. After the buoyancy of the water inside the irrigation pipe 6 on the first float 221 is less than the pulling force of the spring 223, the spring 223 drives the first float 221 to move toward the first shielding plate 17, so that the slide bar 222 moves from the top to the bottom of the slide groove 24. Since the first float 221 is keyed to the inner wall of the irrigation pipe 6, the first float 221 cannot rotate, so that the rotating rod 21 drives the second shielding plate 18 to rotate so that the first drain port 19 and the second drain port 20 are aligned, thereby facilitating the water inside the irrigation pipe 6 to be discharged from the first drain port 19 and the second drain port 20.

[0048] On rainy days, if water enters the irrigation pipe 6 from the water outlet 10, the water inside the irrigation pipe 6 is discharged from the first drain port 19 and the second drain port 20. The bottom end of the irrigation pipe 6 is located lower than the root system of the trees and shrubs, so that the water around the root system of the trees and shrubs can be easily leaked downward through the irrigation pipe 6, thereby reducing the situation where the root system of the trees and shrubs is immersed in water.

[0049] Reference Figure 4 A drainage pipe 25 is fixedly installed at one end of the irrigation pipe 6 away from the second diversion pipe 4, and the interior of the drainage pipe 25 is filled with a second gravel layer 16. A plurality of drainage holes 26 are opened on the peripheral side wall of the drainage pipe 25, and a mesh plate 27 is fixedly installed at one end of the drainage pipe 25 away from the irrigation pipe 6.

[0050] The water in the irrigation pipe 6 is discharged from the first drain port 19 and the second drain port 20 and then enters the drain pipe 25. The drain pipe 25 guides the water to be discharged away from the root system of trees and shrubs, thereby reducing the situation where the roots of trees and shrubs are immersed in water. The second gravel layer 16 reduces the space inside the drain pipe 25, so that the water inside the drain pipe 25 is discharged from the drain hole 26 and the mesh plate 27. The water inside the drain pipe 25 is discharged from the drain hole 26 and the mesh plate 27, so that it is convenient for the water to be dispersed and discharged into the soil and then seep into the ground. At the same time, the second gravel layer 16 and the mesh plate 27 are used to prevent mud and sand from entering the drain pipe 25 from the bottom end of the drain pipe 25 and the drain hole 26.

[0051] Reference Figure 3 , Figure 7 , a plurality of water inlet pipes 28 are fixedly installed on the top side of the pipe body of the second diverter pipe 4, and the water inlet pipes 28 are arranged vertically. A shielding block 29 is fixedly installed on the top of the water inlet pipe 28, and the top side of the shielding block 29 is flush with the ground. The shielding block 29 is provided with a plurality of first water inlet holes 30. Rainwater gathered on the ground will enter the water inlet pipe 28 from the first water inlet holes 30, and the water inside the water inlet pipe 28 will enter the second diverter pipe 4, and then the rainwater will enter the irrigation pipe 6 from the second diverter pipe 4 and be discharged, thereby reducing the occurrence of rainwater gathering on the ground.

[0052] A second non-woven fabric 14 is fixedly mounted on the top side of the shielding block 29 . The second non-woven fabric 14 is used to block mud and sand, thereby reducing the occurrence of mud and sand entering the water inlet pipe 28 .

[0053] Reference Figure 3 , Figure 7 , a shielding assembly 32 is arranged inside the water inlet pipe 28, and the shielding assembly 32 includes a second floating block 321, a guide rod 322 and a blocking rod 323. One end of the guide rod 322 is fixedly connected to the side of the blocking block 29 close to the water inlet pipe 28, the second floating block 321 is located inside the water inlet pipe 28, and the guide rod 322 slides through the second floating block 321. The guide rod 322 is rectangular, the second floating block 321 cannot rotate on the guide rod 322, and the second floating block 321 cannot slide out from the end of the guide rod 322 away from the shielding block 29. The second floating block 321 is provided with a plurality of second water inlet holes 31, and there are a plurality of blocking rods 323, and the blocking rods 323 are arranged one by one corresponding to the first water inlet holes 30. One end of the blocking rod 323 is fixedly connected to the side of the second floating block 321 close to the blocking block, and the other end of the blocking rod 323 is used to enter and exit the first water inlet hole 30.

[0054] When the solenoid valve 1 is opened, the water in the second diverter pipe 4 enters the water inlet pipe 28, and the water in the water inlet pipe 28 drives the second float 321 to move toward the blocking block, so that the blocking rod 323 is inserted into the first water inlet hole 30, thereby closing the first water inlet hole 30. When the solenoid valve 1 is opened for irrigation, the first water inlet hole 30 is closed, thereby reducing the occurrence of water being discharged from the water inlet pipe 28 to the ground.

[0055] After closing the solenoid valve 1, the second float 321 moves downward under the action of gravity, so that the blocking rod 323 is pulled out from the first water inlet hole 30 and the second water inlet hole 31. On rainy days, the accumulated water on the ground enters the water inlet pipe 28 from the first water inlet hole 30 and the second water inlet hole 31, thereby facilitating the drainage of the accumulated water on the ground.

[0056] Reference Figure 1 The soil below the irrigation pipe 6 is paved with a gravel layer 2, on which a third non-woven fabric 33 is laid, and a diversion pipe 34 is connected to the gravel layer 2, one end of which is used to connect to a nearby rainwater well. When the irrigation pipe 6 discharges water to deeper soil, the water enters the gravel layer 2 after passing through the third non-woven fabric 33. Then, the water inside the gravel layer 2 flows from the diversion pipe 34 to the rainwater well.

[0057] A method for cultivating and maintaining trees and shrubs in poorly drained soil, and a device for cultivating and maintaining trees and shrubs in poorly drained soil applied to the present invention, comprise the following steps: According to the depth of the roots of trees and shrubs in the ground, the first shunt pipe 3, the second shunt pipe 4 and the irrigation pipe 6 are buried in the ground, and the bottom end of the irrigation pipe 6 is located at a depth lower than the depth of the roots of the trees and shrubs.

[0058] Plant trees and shrubs in planting zone 9.

[0059] When the solenoid valve 1 is opened, water flows through the first shunt pipe 3, the second shunt pipe 4 and the irrigation pipe 6 in sequence and then sprays out from the irrigation hole to moisten the soil around the roots of trees and shrubs.

[0060] The implementation principle of the cultivation and maintenance device and method for planting trees and shrubs in poorly drained soil in the embodiment of the present application is as follows: the soil moisture sensor 11 detects the humidity of the underground soil in the planting area 9 to form a humidity signal and send it to the controller 12. When the humidity signal is less than the preset threshold, the controller 12 opens the solenoid valve 1, the water from the water source enters the first shunt pipe 3, and the water inside the first shunt pipe 3 flows into the water inlet pipe 28 and the irrigation pipe 6. The water level inside the water inlet pipe 28 and the irrigation pipe 6 increases, so that the shielding component 32 blocks the first water inlet hole 30, and the driving mechanism 22 drives the second shielding plate 18 to rotate through the rotating rod 21, so that the first drainage port 19 and the second drainage port 20 are staggered. After that, water is sprayed from the water outlet 10 to the soil around the roots of trees and shrubs. Since the irrigation pipes 6 on both sides of the second shunt pipe 4 are arranged away from each other from top to bottom, the water outlets 10 are arranged at intervals along the length direction of the irrigation pipe 6, so that water is irrigated from multiple positions from top to bottom to the soil around the roots of trees and shrubs, thereby facilitating the irrigation of the soil around the roots of trees and shrubs.

[0061] When the humidity signal is greater than the preset threshold, the controller 12 closes the solenoid valve 1, and the water level inside the water inlet pipe 28 and the irrigation pipe 6 decreases, so that the shielding assembly 32 opens the first water inlet hole 30, and the driving mechanism 22 drives the second shielding plate 18 to rotate through the rotating rod 21, so that the first drainage port 19 and the second drainage port 20 are aligned. On rainy days, the accumulated water on the ground enters the water inlet pipe 28 from the first water inlet hole 30, and the water inside the water inlet pipe 28 enters the irrigation pipe 6 from the second diversion pipe 4. When the soil around the roots of trees and shrubs has a high moisture content, the water in the soil enters the first gravel layer 15 to gather, and then the water enters the irrigation pipe 6 from the water outlet 10.

[0062] Then the water inside the irrigation pipe 6 is discharged from the first drain port 19 and the second drain port 20 into the drain pipe 25, and the water is guided by the drain pipe 25 to be discharged from a position lower than the roots of trees and shrubs, and the water enters the gravel layer 2. Then the water inside the gravel layer 3 is discharged from the diversion pipe 34 to the rainwater well, thereby reducing the accumulation of rainwater on the ground and reducing the immersion of the roots of trees and shrubs in water.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
