Description

Technical Field

[0001] This invention relates to the field of green wall irrigation technology, and in particular to an integrated intelligent irrigation and nutrient slow-release device for biomimetic root systems of green walls. Background Technology

[0002] Bionic root systems are artificial root systems designed and constructed by imitating the structure and function of natural root systems. One application is to simulated ornamental plants. After the simulated root system is connected to the simulated ornamental plant, it holds the soil firmly, thereby improving the simulated ornamental plant's resistance to external environmental pressures and maintaining its stability as a landscape feature. Another application is to green walls or lawns. Plants are tethered to the bionic root system, which holds the soil firmly, keeping sparsely rooted green wall or lawn plants stable and preventing them from falling off the soil. Nutrient solutions and water can also be delivered to the roots of the green wall or lawn plants, ensuring that the plants grow along the bionic root system into natural root systems, maintaining the normal growth of the green wall or lawn plants, and ultimately maintaining the ecological function and landscape stability of the green wall or lawn plants.

[0003] However, existing bionic root systems often have complex structures in order to simulate natural root systems. The natural root system of the green wall plant grows along the bionic root system. Although this ensures strong pressure resistance, the bionic root system cannot be separated from the natural root system, which limits the further growth of the natural root system. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an integrated intelligent irrigation and nutrient slow release device for biomimetic root systems of green walls.

[0005] This invention provides an integrated intelligent irrigation and nutrient slow-release device for biomimetic root systems in green walls, comprising:

[0006] The liquid supply module includes a first main pipe for conveying water and a second main pipe for conveying slow-release nutrient solution;

[0007] Several intermediate modules, including a three-way electrically controlled valve connecting the first main pipe and the second main pipe, wherein the remaining interfaces of the three-way electrically controlled valve are connected to a connecting pipe;

[0008] Several simulated root modules, each corresponding to an intermediate module, include an end cap connected to the plant, a plug at the bottom of the end cap, and a first channel and a second channel for the plant roots to pass through in the middle of the end cap and the plug. The end of the connecting pipe away from the three-way electrically controlled valve is connected to the second channel.

[0009] The simulated root module also includes a cylindrical assembly detachably connected to the insert block.

[0013] The second installation chamber has an air pipe that is detachably installed inside by threads. A conical block is detachably installed on the top of the air pipe by threads, and the top of the conical block has an air intake channel that communicates with the inside of the air pipe.

[0014] According to the technical solution provided in the embodiments of this application, the air pipe is further provided with an airflow assembly. The airflow assembly includes a main shaft that can rotate at the bottom of the conical block. A fan blade is fitted in the middle of the main shaft, and a conical sleeve is coaxially provided at the bottom. The outer surface of the conical sleeve is provided with a guide plate that extends upward at an incline. The axis of the conical sleeve coincides with the axis of the water inlet.

[0015] According to the technical solution provided in the embodiments of this application, the bottom of the conical block is provided with a third mounting chamber that communicates with the top of the air pipe. The air intake channel includes a horizontal hole that extends laterally through the outer surface of the conical block to the third mounting chamber, and a downward oblique hole that extends obliquely upward through the bottom surface of the conical block to the horizontal hole. The outer opening of the horizontal hole away from the third mounting chamber is welded and sealed.

[0016] According to the technical solution provided in the embodiments of this application, the liquid supply module includes a first storage tank for storing water, the bottom of the first storage tank being connected to a first main pipe through a shut-off valve, and the liquid supply module also includes a second storage tank for storing slow-release nutrient solution, the second storage tank being connected to a second main pipe through a shut-off valve;

[0017] The first and second storage tanks are equipped with support legs at the bottom to raise the height, and the first main pipe, the second main pipe and the base are placed on the ground.

[0018] According to the technical solution provided in the embodiments of this application, both ends of the insert block and the main cylinder along the first direction are provided with pin holes that penetrate to the second channel. A pin is inserted into one of the pin holes, and a first branch pipe is inserted into the other pin hole.

[0019] According to the technical solution provided in the embodiments of this application, the root system groove includes a first groove, two second grooves and four third grooves. One end of the first groove is connected to a second channel, and the other end is connected to two second grooves. One end of the second groove away from the first groove is connected to two third grooves.

[0020] According to the technical solution provided in the embodiments of this application, the bottom of the main cylinder is provided with an inner cylinder, and a spring is provided inside the inner cylinder. The bottom end of the spring is connected to the bottom surface of the inner cylinder, and the top end is connected to the bottom surface of the extrusion plate.

[0021] The inner cylinder is fitted with an outer cylinder. Both the inner and outer cylinders have annular end plates at their top and bottom. There is an installation space between the inner and outer cylinders. The installation space contains a heater and a temperature and humidity sensor for detecting the soil temperature and humidity inside the main cylinder.

[0022] According to the technical solution provided in the embodiments of this application, the bottom of the main cylinder is provided with a plurality of root system installation holes, and the root system assembly includes a Y-shaped oblique tee inserted into the root system installation hole. The Y-shaped oblique tee has an obliquely upward branch pipe, and the end of the branch pipe is provided with an angle plate. The sharp corner of the angle plate is downward, and one end is provided with a fitting groove that fits with the outer surface of the branch pipe.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] This invention divides the traditionally complex bionic root system into a liquid supply module and a bionic root module. The liquid supply module supplies slow-release nutrient solution and water, while the bionic root module provides gripping ability, ensuring normal irrigation, nutrient supply, and strong soil adhesion. Furthermore, the bionic root module consists of an end cap, a main cylinder, and a root system component. The plant is secured to the end cap, which is then installed on the main cylinder. After the plant naturally roots, simply remove the end cap and take out the main cylinder and root system component, allowing the natural root system to contact the soil and ensuring further plant growth. This solves the problem of existing bionic root systems being unable to detach from natural root systems. Additionally, the root system component consists of a Y-shaped oblique tee and a corner plate. The downward-facing corner of the corner plate reduces digging difficulty, allowing the root system component to be inserted into the soil, improving installation convenience. This structure also ensures the stability of the root system component and main cylinder inserted into the soil. Finally, this structure facilitates subsequent separation of the soil from the root system component, improving separation convenience. Furthermore, an insert block, root groove, and compression plate are provided at the bottom of the end cap, allowing the natural roots to grow along the root groove and form an outward-expanding natural root system. This ensures that the natural roots can hold the soil firmly after being buried, ensuring that the natural roots have a strong gripping ability and guaranteeing the plant's subsequent stable growth and high gripping strength.

[0025] In addition, the liquid supply module includes a first main pipe for conveying water and a second main pipe for conveying slow-release nutrient solution. It is connected to the main cylinder via a three-way electrically controlled valve. The opening and closing of the three-way electrically controlled valve can be controlled by a remote terminal to achieve the purpose of intelligent irrigation. Furthermore, soil, heater and temperature and humidity sensors are installed inside the main cylinder. The temperature and humidity sensors provide real-time data parameters to the remote terminal, which can facilitate the remote terminal to control the opening and closing of the three-way electrically controlled valve to adjust the soil moisture inside the main cylinder. It can also facilitate the remote terminal to control the heater to adjust the soil temperature inside the main cylinder, ensuring that the natural root system can develop and grow stably.

[0026] In addition, an oxygenation module is installed between the three-way electric control valve and the main cylinder. The cross-section of the water inlet is reduced, the water pressure is increased, and the sprayed water flow speed is increased, so that the water or slow-release nutrient solution can be fully mixed with air, increasing the oxygen content in the liquid and improving the growth requirements of plants. It is equipped with an air pipe, a conical block, and an air intake channel to prevent liquid from overflowing and to prevent external dust and debris from contacting the liquid. A conical sleeve, a main shaft, a guide plate, and a fan blade are installed at the bottom of the conical block. The upward force of the liquid drives the conical sleeve, guide plate, and fan blade to rotate. The fan blade drives the gas flow, improving the gas flow efficiency and preventing the oxygenation efficiency from decreasing due to airflow stagnation.

[0048] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0049] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0050] Please refer to Figures 1-10 An embodiment of the present invention provides an integrated intelligent irrigation and nutrient slow-release device for a biomimetic root system of a green wall, comprising:

[0051] The liquid supply module 1 includes a first main pipe 14 for conveying water and a second main pipe 15 for conveying slow-release nutrient solution.

[0052] refer to Figure 1As shown, the liquid supply module 1 includes a first storage tank 11 for storing liquid water. The bottom of the first storage tank 11 is connected to the first main pipe 14 via a shut-off valve. The liquid supply module 1 also includes a second storage tank 12 for storing slow-release nutrient solution. The second storage tank 12 is connected to the second main pipe 15 via a shut-off valve. The plant is irrigated with liquid water, and then nutrients are provided to the plant roots via the slow-release nutrient solution. Optionally, the slow-release nutrient solution is a slow-release organic fertilizer, made from organic materials through processes such as bio-fermentation, which allows nutrients to be released slowly. Liquid urea-formaldehyde slow-release fertilizer can be used, containing carbon, organic acids, humic acid, fulvic acid, palmitic acid, alginic acid, concentrated nitrogen, phosphorus, potassium, and other nutrients. By employing urea-formaldehyde slow-release and polyphosphate slow-release technologies, nutrients are slowly released into the plant, resulting in a longer effective period, preventing nutrient deficiency in the plant, stimulating the plant to grow more white roots, and enhancing its ability to absorb water and nutrients from the soil.

[0053] Furthermore, the bottom of the first storage tank 11 and the second storage tank 12 are provided with support legs 13 for raising the height. The first main pipe 14 and the second main pipe 15 are placed on the ground. Under the action of gravity, the water and slow-release nutrient solution can flow steadily into the first main pipe 14 or the second main pipe 15 to ensure the delivery of liquid.

[0054] Several intermediate modules, including a three-way electrically controlled valve 2 connecting the first main pipe 14 and the second main pipe 15, with a connecting pipe 3 connected to the remaining interface of the three-way electrically controlled valve 2; the valve body of the three-way electrically controlled valve 2 can be referenced. Figure 10 The valve core uses a bent channel inside. When the valve core is rotated, the valve body has three states. In the first state, the left opening is connected to the middle opening, and the water in the first main pipe 14 is sent into the connecting pipe 3. In the second state, the right opening is connected to the middle opening, and the slow-release nutrient solution in the second main pipe 15 is sent into the connecting pipe 3, so as to achieve the purpose of delivering water or slow-release nutrient solution respectively. In the third state, the valve core blocks the middle opening, and the two ends of the bent channel of the valve core do not coincide with the two side openings, so as to keep it in a normally closed state when watering is not being carried out.

[0055] Several simulated root modules 5 correspond one-to-one with each intermediate module, including an end cap 51 connected to the plant. The bottom of the end cap 51 is provided with an insertion block 54. The middle of the end cap 51 and the insertion block 54 are provided with a first channel 52 and a second channel 56 for the plant roots to pass through. The end of the connecting pipe 3 away from the three-way solenoid valve 2 is connected to the second channel 56. Optionally, the top of the end cap 51 is provided with several wound metal wires 53 around the first channel 52. Each wound metal wire 53 is tightly wrapped around the outer surface of the plant to realize the connection between the plant and the end cap 51. Water or slow-release nutrient solution will flow from the connecting pipe 3 into the interior of the second channel 56 to provide the required water or slow-release nutrient solution to the bottom of the plant.

[0056] The simulated root module 5 also includes a cylindrical assembly 6 detachably connected to the insert block 54. The cylindrical assembly 6 includes a main cylindrical body 69 detachably connected to the insert block 54 and filled with soil. The bottom of the insert block 54 is evenly provided with a number of root grooves 59 around the second channel 56. Each root groove 59 extends from the center of the second channel 56 toward the cylindrical wall side of the main cylindrical body 69. The main cylindrical body 69 is provided with an extrusion plate 65, which is used to restrict the soil and plant roots in the root grooves 59.

[0057] The simulation root module 5 also includes a root system component 7 located at the bottom of the main cylinder 69, which is used to increase the grip strength of the main cylinder 69.

[0058] This application divides the traditional complex bionic root system into a liquid supply module 1 and a simulated root module 5. The liquid supply module 1 is used to supply slow-release nutrient solution or water to achieve irrigation and fertilization, while the root system component 7 of the simulated root module 5 provides stable soil gripping ability, thus realizing the functions of irrigation, nutrient supply and strong soil gripping of traditional bionic root systems. In addition, because the plant is tied to the end cap 51, and the end cap 51 and the insertion block 54 are detachably installed on the main cylinder 69, after the plant's natural root system has grown, the main cylinder 69 and the root system component 7 can be removed, and the end cap 51 and the plant's natural root system can be reburied in the soil. The detachable design allows the natural root system to contact the soil, ensuring further plant growth and solving the problem that existing bionic root systems cannot detach from natural root systems.

[0059] Furthermore, because the root groove 59 at the bottom of the insert 54 spreads outward from the center and is held in place by the pressing plate 65, the plant's natural roots will spread outward along the root groove 59, forming an outward-expanding natural root system. This ensures that the natural roots can hold the soil firmly after being buried, ensuring that the natural roots have a strong gripping ability, thus guaranteeing the plant's subsequent stable natural growth and high gripping ability.

[0060] In some embodiments, the root groove 59 includes a first groove 591, two second grooves 592 and four third grooves 593. One end of the first groove 591 is connected to the second channel 56 and the other end is connected to the two second grooves 592. The end of one second groove 592 away from the first groove 591 is connected to the two third grooves 593.

[0061] refer to Figure 3 and Figure 8The further away the plant's natural root system is from the main body, the higher its dispersion. In addition, through the design of this diffusion-type root groove 59, the closer to the main body of the plant, the more numerous the roots are, and the stronger they are after intertwining. The number of roots at the edge is small and the structural strength is low. Therefore, during secondary planting, that is, when the main cylinder 69 and root component 7 are removed and the plant is planted along with the end cap 51, the roots inside the first groove 591 are basically not tilted downwards, while the roots in the second groove 592 will tilt downwards. The roots in the third groove 593, due to their small number and low structural strength, will form a large tilt downwards or vertical downwards, ultimately achieving an umbrella-shaped downward effect of the natural root system. This allows the natural root system to better integrate with the soil, ensuring the plant's subsequent stable growth and strong grip. Optionally, the width of the first groove 591, the second groove 592, and the third groove 593 decreases sequentially to ensure that the combination of multiple roots near the main body of the plant can be better accommodated in the corresponding groove.

[0062] In some embodiments, an inner cylinder 61 is provided at the bottom of the main cylinder 69, and a spring 64 is provided inside the inner cylinder 61. The bottom end of the spring 64 is connected to the bottom surface of the inner cylinder 69, and the top end is connected to the bottom surface of the extrusion plate 65. The spring 64 pushes the extrusion plate 65 upward, so that the soil is squeezed into the root groove 59. There is no soil or only a small amount of soil between the insert block 54 and the extrusion plate 65, which ensures that the natural roots of the plant can grow smoothly along the root groove 59. If the extrusion plate 65 and the insert block 54 are in a rigid relationship, the extrusion plate 65 cannot move. After a long period of growth, the natural roots will fill the root groove 59, causing the water or slow-release nutrient solution to be unable to flow downward, resulting in the stagnation or even death of the natural roots. However, through the flexible push of the spring 64, even after the natural roots have grown extensively, there is still space for the water or slow-release nutrient solution to flow downward, ensuring the continued growth of the natural roots.

[0063] In some embodiments, an outer cylinder 62 is provided around the inner cylinder 61. Both the inner cylinder 61 and the outer cylinder 62 are provided with annular end plates 63 at their top and bottom ends. There is an installation space between the inner cylinder 61 and the outer cylinder 62. A heater 66 is provided inside the installation space, as well as a temperature and humidity sensor 67 for detecting the soil temperature and humidity inside the main cylinder 69.

[0064] refer to Figure 3 and Figure 4As shown, the soil moisture and temperature data inside the main cylinder 69 are obtained through the temperature and humidity sensor 67 and transmitted to the remote terminal. The remote terminal controls the temperature adjustment of the heater 66 to keep the soil inside the main cylinder 69 in a suitable environment for natural root growth. Alternatively, the remote terminal can control the three-way solenoid valve 2 to deliver water or slow-release nutrient solution to the soil inside the main cylinder 69 to regulate humidity and supplement nutrients, ultimately achieving the function of intelligent irrigation. Optionally, the remote terminal can be a commonly used computer, which can control the opening and closing of the corresponding electrical components through programming software. The heater 66, temperature and humidity sensor 67, and three-way solenoid valve 2 can be connected to the remote terminal via wires.

[0065] In some embodiments, both ends of the insert block 54 and the main cylinder 69 along the first direction are provided with pin holes 57 that extend to the second channel 56. A pin 58 is inserted into one pin hole 57, and a first branch pipe 31 is inserted into the other pin hole 57.

[0066] refer to Figure 3 and Figure 4 As shown, by pulling out the pin 58 and the first branch pipe 31, the insertion block 54 can be separated from the main cylinder 69. Optionally, the top of the insertion block 54 is provided with an installation groove 510. The installation groove 510 is annular and fitted with a sealing rubber ring 55. On the one hand, the deformation of the sealing rubber ring 55 achieves a preliminary connection effect. On the other hand, by sealing the gap between the insertion block 54 and the main cylinder 69, the natural roots will grow downward along the gap between the extrusion plate 65 and the main cylinder 69 after growth.

[0067] In some embodiments, the bottom of the main cylinder 69 is provided with a plurality of root system mounting holes 68, and the root system assembly 7 includes a Y-shaped oblique tee 71 inserted into the root system mounting hole 68. The Y-shaped oblique tee 71 has an obliquely upward branch pipe, and the end of the branch pipe is provided with a corner plate 72. The sharp corner of the corner plate 72 is downward, and one end is provided with a fitting groove 73 that fits with the outer surface of the branch pipe.

[0068] refer to Figure 2 and Figure 9As shown, traditional complex bionic root systems require digging large pits for burial, while this application only requires shallow pits. By stepping on or pushing the main cylinder 69, the root system component 7 can be stably inserted into the soil using the downward-facing corner of the angle plate 72 and the upward-sloping direction of the branch pipes. The upward-facing opening of the angle plate 72 prevents the root system component 7 and the main cylinder 69 from detaching from the soil, achieving stable ground grip. The fitting groove 73 positions a portion of the angle plate 72 below the branch pipes, and the sharp corner reduces the resistance to downward insertion of the branch pipes into the soil, improving the ease and stability of insertion. Optionally, several Y-shaped oblique tees 71 are also provided below the Y-shaped oblique tee 71 inside a root system mounting hole 68, with each Y-shaped oblique tee 71 having a different branch pipe orientation, further improving the ground grip of the root system component 7.

[0069] In some embodiments, the connecting pipe 3 is further provided with an oxygenation module 4, which is used to increase the oxygen content of the aqueous solution or slow-release nutrient solution. By increasing the oxygen content of the solution, the plant roots respire vigorously, have sufficient energy, divide cells quickly, and root primordia are easily formed, thereby improving the plant root growth effect.

[0070] In some embodiments, the connecting pipe 3 includes a second branch pipe 32 connected to the three-way solenoid valve 2 and a first branch pipe 31 connected to the second channel 56. The oxygenation module 4 includes a base 41 disposed between the first branch pipe 31 and the second branch pipe 32. The base 41 has a second mounting chamber 48 inside. The bottom of the second mounting chamber 48 has a water inlet 412 connected to the second branch pipe 32. The bottom side surface of the second mounting chamber 48 has a water outlet 411 connected to the first branch pipe 31.

[0071] The second installation chamber 48 has an air pipe 42 that can be detachably installed inside by threads. A conical block 43 is detachably installed on the top of the air pipe 42 by threads. The top of the conical block 43 is provided with an air intake channel 47 that communicates with the inside of the air pipe 42.

[0072] refer to Figure 3 and Figure 5As shown, liquid water or slow-release nutrient solution flows into the inlet 412 through the second branch pipe 32. The reduced diameter of the inlet 412 increases the liquid volume, raising the upward flow height and allowing for better combination with air as the liquid falls back, thus increasing its oxygen content. The falling liquid returns to the second installation chamber 48 and flows along the outlet 411 and the first branch pipe 31 into the second channel 56, achieving irrigation or nutrient solution application. Optionally, the top of the air pipe 42 is fitted with a first external threaded sleeve 45, and the bottom is fitted with a second external threaded sleeve 49. The second thread is formed by tapping the top of the second installation chamber 48, and the connection between the second external threaded sleeve 49 and the second thread enables a detachable connection between the air pipe 42 and the base 41. Similarly, the bottom of the conical block 43 has a first installation chamber 44, the bottom of which is tapped to form a first thread. The first external threaded sleeve 45 connects to the first thread, enabling a detachable connection between the air pipe 42 and the conical block 43. Alternatively, the outer surface of the second external threaded sleeve 49 is also provided with a limiting retaining ring 410 to prevent the second external threaded sleeve 49 from moving excessively downward and blocking the outlet 411.

[0073] The base 41 is placed on the ground but is higher than the end cap 51. Because the first storage tank 11 and the second storage tank 12 are raised by the support legs 13, the height of their liquid outlets is much higher than the bottom surface. As a result, the liquid sprayed from the water inlet 412 is different from the liquid level in the storage tank, providing the power for liquid transportation. There is no need to purchase an additional water pump, which reduces the cost of using the product and makes it easier to promote its use. More preferably, the first branch pipe 31 is a rigid pipe and the second branch pipe 32 is a flexible pipe, so that the second branch pipe 32 can be fully bent and placed, making it easy for the base 41 and the first branch pipe 31 to move to one side, so that the first branch pipe 31 can be pulled out from the pin hole 57.

[0074] In some embodiments, the air pipe 42 is further provided with an airflow assembly 8. The airflow assembly 8 includes a self-rotating main shaft 82 located at the bottom of the conical block 43. A fan blade 83 is fitted in the middle of the main shaft 82, and a conical sleeve 84 is coaxially provided at the bottom. A guide plate 85 extending upward at an inclined angle is provided on the outer surface of the conical sleeve 84, and the axis of the conical sleeve 84 coincides with the axis of the water inlet 412.

[0075] refer to Figure 5 and Figure 6As shown, when liquid is sprayed from the inlet nozzle 412 from bottom to top, the liquid contacts the tip of the conical sleeve 84, disperses, and then contacts the guide plate 85. Due to the inclined setting of the guide plate 85, the conical sleeve 84 is pushed to rotate, which in turn drives the main shaft 82 to rotate, and finally drives the fan blade 83 to rotate, driving the flow inside the air pipe 42, so that the liquid can come into contact with the flowing air, improving the integration of air into the liquid and increasing the oxygen content. In addition, because the axis of the conical sleeve 84 coincides with the axis of the inlet nozzle 412, the sprayed liquid is evenly diffused, ensuring the uniform rotation of the conical sleeve 84 and the main shaft 82, avoiding energy consumption and rotational instability caused by deflection. Optionally, the conical sleeve 84, the main shaft 82, and the fan blade 83 are made of carbon fiber, which has high structural strength and will not cause the rotation to be impossible due to excessive weight. The third mounting chamber 46 is located on top of the first mounting chamber 44, and a bearing 81 is provided on the top of the third mounting chamber 46, with the main shaft 82 inserted into the bearing 81.

[0076] In some embodiments, the bottom of the conical block 43 is provided with a third mounting chamber 46 communicating with the top of the air pipe 42. The air intake channel 47 includes a horizontal hole 471 that extends laterally through the outer surface of the conical block 43 to the third mounting chamber 46, and a downward oblique hole 472 that extends obliquely upward through the bottom surface of the conical block 43 to the horizontal hole 471. The outer opening of the horizontal hole 471 away from the third mounting chamber 46 is welded and sealed.

[0077] refer to Figure 5 As shown, through two-stage processing, only the outer opening of the horizontal hole 471 needs to be sealed to ensure stable airflow in the air intake channel 47. On the one hand, drilling is more convenient because only straight drilling is required. On the other hand, the downward inclined hole 472 is tilted downward and the outer opening of the horizontal hole 471 is sealed, which not only ensures stable gas flow in the air intake channel 47, but also reduces the entry of external particles or plant debris into the air pipe 42, avoiding blockage of the water outlet 411 or the water inlet 412.

[0078] The usage process includes the following steps:

[0079] First, the temperature and humidity sensor 67 detects the soil moisture and temperature inside the main cylinder 69. If the temperature is too low, the heater 66 is controlled by the remote terminal to heat the soil. If the humidity is too low, the three-way solenoid valve 2 is controlled by the remote terminal to allow the water in the first storage tank 11 to flow along the first main pipe 14, the three-way solenoid valve 2 and the connecting pipe 3 to the second channel 56, flowing above the extrusion plate 65 and then into the main cylinder 69 for humidity regulation. The three-way solenoid valve 2 is also periodically controlled by the remote terminal to allow the slow-release nutrient solution in the second storage tank 12 to flow along the second main pipe 15, the three-way solenoid valve 2 and the connecting pipe 3 to the second channel 56, flowing to the roots of the plant to supply nutrients and promote growth and rooting.

[0080] When the liquid passes through the connecting pipe 3, it passes through the oxygenation module 4. Through the upward-facing water inlet 412, the liquid is sprayed upward, pushing the guide plate 85 of the conical sleeve 84, which drives the rotation of the main shaft 82 and the fan blade 83. The fan blade 83 drives the airflow, so that the upward-sprayed liquid can come into contact with the flowing air, increasing the oxygen content of the liquid and promoting root growth.

[0081] Furthermore, after long-term cultivation of the green wall plants, the natural root system of the plants has grown and taken shape. At this time, it is necessary to move the first branch pipe 31 to one side and the pin 58 to the other side to separate the insert 54 and the main cylinder 69, forming a combined unit of plant roots, end cap 51, insert 54 and natural root system that spreads outward and droops at the edges. Other components are removed, and the original pit of the main cylinder 69 is retained.

[0082] The combined units are placed into the pits for secondary planting. The soil is then filled in and leveled to separate the plant's natural root system from the biomimetic root system. Due to the design of the special root groove 59, the closer to the main body of the plant, the more numerous and stronger the roots become after they intertwine. The roots at the edge are fewer in number and have lower structural strength. During secondary planting, the roots inside the first groove 591 are more numerous and robust, and they do not tilt or droop. The roots inside the second groove 592 will tilt and droop. The roots in the third groove 593 are fewer in number and have lower structural strength, thus forming a large tilt or vertical droop. Ultimately, this achieves an umbrella-shaped drooping effect of the natural root system, allowing the natural root system to better integrate with the soil and ensuring the plant's subsequent stable growth and strong grip.
