Description

Technical Field

[0001] This invention relates to the field of Polygonum multiflorum cultivation technology, specifically a Polygonum multiflorum cultivation device. Background Technology

[0002] Polygonum multiflorum is a precious Chinese medicinal herb. With the surge in market demand, wild resources can no longer meet the industry's needs, and large-scale artificial cultivation has gradually become the main supply method. Polygonum multiflorum cultivation is a long-term cultivation method, often measured in years. It has been found in continuous cultivation that after two consecutive years of cultivation, the number of Fusarium oxysporum in the soil increases by 3.8 times. As a facultative parasitic fungus, this pathogen can directly infect plant tissues and survive in the soil for a long time, which has a great impact on the normal growth of Polygonum multiflorum.

[0003] Current prevention and control methods require full-soil tillage followed by fungicide application or direct soil replacement. This is not only costly and time-consuming, impacting planting costs, but excessive use of fungicides can also affect planting quality. Furthermore, continuous cropping can lead to the accumulation of other harmful fungi in the soil, further affecting planting quality.

[0004] Experiments have shown that temperature control, or the use of ozone and ultraviolet light in the soil, can effectively kill and inhibit the fungi that affect the cultivation of Polygonum multiflorum. Ozone, as a strong oxidant, can destroy the cell membrane, DNA, and enzyme system of the fungi; ultraviolet light inhibits the reproduction of the fungi by destroying the pyrimidine dimers of the fungi's DNA. However, it is relatively difficult to implement this method during the cultivation period by placing the ozone or ultraviolet light inside the soil.

[0005] Therefore, it is necessary to provide an automated intelligent planting device for Polygonum multiflorum, which is also a multifunctional planting device that can simultaneously perform sterilization and bacteriostasis inside the soil during the planting period. Summary of the Invention

[0006] This invention proposes a Polygonum multiflorum planting device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A Polygonum multiflorum planting device includes a box body, a partition inserted in the middle of the box body, a planting section above the partition, a drainage section below the partition, an ultraviolet component and a cylindrical component integrating sterilization, watering, soil loosening and heating are provided in the planting section and extend through the planting section to the outside of the box body, and a negative pressure drainage structure is provided in the drainage section.

[0009] Preferably, the cylindrical assembly has two sets, located on both sides of the ultraviolet assembly. Each cylindrical assembly includes an assembly opening on the side of the main body, and an assembly groove on the inner wall of the main body corresponding to the assembly opening. A rotating outer cylinder is inserted between the assembly opening and the assembly groove. A fixed inner cylinder is detachably inserted into the rotating outer cylinder, and a heating rod, ozone tube, or ultraviolet lamp is inserted into the fixed inner cylinder. The outer circumference of the rotating outer cylinder is provided with several through grooves communicating with the interior of the rotating outer cylinder, and a stirring rod is inserted into each of the through grooves. The end of the fixed inner cylinder facing the through groove has an arc-shaped conical structure, and the end of the stirring rod facing the through groove has an arc-shaped hemispherical structure. The end of the arc-shaped conical structure of the fixed inner cylinder contacts the end of the arc-shaped hemispherical structure of the stirring rod, facilitating the stirring rod to be pushed out of the through groove when the fixed inner cylinder is inserted into the rotating outer cylinder. A limiting plate is used to prevent the stirring rod from detaching from the through groove, restricting the end of the stirring rod with the limiting plate within the through groove.

[0010] Preferably, a limiting plate is provided on the outer peripheral surface of the joint between the stirring rod and the through groove, and the diameter of the opening end of the through groove is smaller than the diameter of the limiting plate.

[0011] Preferably, the rotating outer cylinder has several limiting grooves along its length, and the fixed inner cylinder has limiting blocks that insert into the limiting grooves on its outer side. The fixed inner cylinder is a hollow cylinder with internal water injection holes on its surface corresponding to the through grooves and communicating with the hollow interior of the fixed inner cylinder. The stirring rod has a hollow, through-hole external water injection hole. This ensures that the internal water injection hole of the fixed inner cylinder communicates with the through groove and with the external water injection hole of the stirring rod. The open end of the fixed inner cylinder can be connected to the external water injection device using conventional pipe connection methods, such as threaded connection, flange connection, welding, grooved connection (clamp connection), compression fitting connection, hot melt connection, socket connection, etc., without being limited to a single method.

[0012] Preferably, each of the two rotating outer cylinders is connected to a gear one at one end of the assembly port one, and a chain is connected between the two gears one. A motor is provided on one side of the box body, and a gear two is connected to the output shaft of the motor. The gear two is connected to the chain.

[0013] Preferably, the ultraviolet component includes an assembly port two on the side of the main body opposite to the first assembly port. The main body has an assembly groove two corresponding to the second assembly port. A transparent sleeve is inserted between the second assembly port and the second assembly groove. An ozone tube is located in the center of the transparent sleeve. Several vents communicating with the interior of the transparent sleeve are located on its outer circumference. Several ultraviolet lamps are arranged in a ring around the inner sidewall of the transparent sleeve with the center as the axis. The ozone tube is connected to an ozone generator (not shown in the accompanying drawings, representing existing mature technology, and not considered the only one). The vents allow ozone to enter the soil, and the transparent sleeve facilitates comprehensive irradiation of the soil by the ultraviolet lamps.

[0014] Preferably, the main body of the box below the second assembly port is provided with an assembly port three, and the main body of the box is provided with an assembly groove three corresponding to the assembly port three. The partition is inserted and installed between the assembly port three and the assembly groove three. The upper surface of the partition is provided with several guide strips distributed in a wavy pattern. The partition is also provided with several guide grooves connecting the planting part and the drainage part. The guide grooves are provided with filter screens. The filter screens are used to prevent soil from clogging the guide grooves and to prevent soil from falling into the drainage part. The guide strips facilitate the diversion of waste liquid, allowing the waste liquid in the soil to flow into the guide grooves.

[0015] Preferably, the negative pressure drainage structure includes a lower bottom surface inside the tank body, which is an inclined surface. A negative pressure pipe is provided on one side of the lower end of the inclined surface, extending out of the tank body and connected to a negative pressure generator. A temperature sensor and a humidity sensor are provided on the tank body, with the probe of the humidity sensor extending into the tank body. The negative pressure generator is not shown in the accompanying drawings; it is a common device on the market and will not be described in detail here.

[0016] The Polygonum multiflorum planting device can be a soil heating device, a soil fungal treatment device, or a soil loosening device.

[0017] A sterilization method based on the above-mentioned Polygonum multiflorum planting device includes the following steps:

[0018] 1) Assemble the UV component and the cylindrical component separately, and pass through the planting part of the main body of the box. Place soil in the planting part and plant Polygonum multiflorum. The UV component passes through the assembly port two and is installed on the assembly slot two. The rotating outer cylinder passes through the assembly port one and is installed on the assembly slot one. The fixed inner cylinder is inserted into the rotating outer cylinder, and the stirring rod extends out of the through slot.

[0019] 2) Soil moisture is detected by a humidity sensor. When the moisture level is lower than the planting requirements, nutrient solution and water can be injected into the soil through the inner and outer water channels of the fixed inner cylinder. This ensures that the water or nutrient solution is fully absorbed into the soil without excessive watering, which could lead to fungal growth. A diluted pesticide solution for killing Fusarium oxysporum or other fungi can be injected intermittently. The soil temperature is detected by a temperature sensor. A heating rod can be inserted into the hollow part of the fixed inner cylinder to directly heat and sterilize the soil. The heating rod can adjust the soil planting temperature and further sterilize or inhibit the growth of some low-temperature fungi, reducing the use of pesticides. Generally, the temperature should not exceed a certain degree during planting. When not planting, the temperature can be increased for sterilization, significantly reducing pesticide use. Alternatively, an ozone tube or ultraviolet lamp can be inserted into the hollow part of the fixed inner cylinder to directly sterilize the soil with ozone and ultraviolet light.

[0020] 3) Wastewater seeping from the soil flows into the drainage section through a guide channel. Because the bottom of the drainage section is sloping, the wastewater is concentrated by gravity at the inlet of the negative pressure pipe. Activating the negative pressure pump allows the wastewater to be discharged outside the drainage section for treatment through the negative pressure pipe; this further improves wastewater treatment, preventing excessive moisture from causing bacterial growth and reducing the need for chemical solutions.

[0021] 4) During or after the planting of Polygonum multiflorum, the motor can be started at any time. Through the meshing and linkage of gear one, gear two and chain, the outer cylinder is driven to rotate, which in turn drives the mixing rod to rotate to loosen the soil in the planting area.

[0022] 5) During or after the planting period of Polygonum multiflorum, ozone and ultraviolet light can be generated by ozone tubes and ultraviolet lamps to sterilize or inhibit the growth of bacteria in the soil, thereby further reducing the use of pesticide solutions.

[0023] A method for cultivating Polygonum multiflorum involves placing soil in a planting section and planting Polygonum multiflorum, and includes the above-mentioned sterilization method based on the Polygonum multiflorum planting device.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] This device's cylindrical component utilizes internal and external water channels within a fixed inner cylinder to precisely inject nutrient solution and water, achieving precise planting by embedding water and nutrients into the soil. This allows the soil to fully absorb water and fertilizer, improving the growth rate of *Polygonum multiflorum* (He Shou Wu). Simultaneously, it avoids creating a damp environment conducive to fungal growth due to excessive moisture, reducing the likelihood of fungal proliferation at its source. Furthermore, during planting, diluted pesticide solutions can be injected as needed to specifically kill harmful fungi such as *Fusarium oxysporum*, further ensuring the growth rate of *Polygonum multiflorum*. Additionally, heating rods, ozone tubes, or ultraviolet lamps can be directly inserted into the hollow part of the fixed inner cylinder to provide multiple options for heating or sterilizing / inhibiting the soil. The device achieves effective sterilization and bacteriostasis by controlling the temperature during the planting period to a range suitable for the growth of Polygonum multiflorum and inhibiting the growth of low-temperature fungi, without relying on large amounts of pesticides. When not in use, the temperature can be increased for deep sterilization, effectively reducing the use of chemical agents, lowering planting costs, reducing pollution to the soil and environment, and further improving the growth rate. The device uses a motor to drive gears one and two and a chain to rotate the outer cylinder and stirring rod, achieving automated loosening of the soil in the planting area. The multi-cylinder component of this device is located in the planting area, achieving multiple effects with a simple structure.

[0026] In addition, the installation of ozone tubes and ultraviolet lamps can sterilize the fungi in the soil at any time during the planting period or after harvesting of Polygonum multiflorum, further reducing fungal growth, reducing the use of chemical solutions, improving the soil environment, and further enhancing the application of automation and intelligence.

[0027] Temperature sensors monitor soil temperature in real time to block the spread of fungi. The bottom of the drainage section in the device is designed with an inclined surface. Waste liquid seeping from the soil flows into the drainage section through the guide channel and is concentrated at the negative pressure pipe opening due to gravity. The negative pressure machine can discharge and treat the waste liquid by starting it up, which avoids the accumulation of waste liquid in the planting area and prevents the growth and spread of fungi due to excessive water accumulation. This further reduces the risk of fungal growth, improves the soil environment, and enhances the application of automation and intelligence.

[0028] This invention effectively realizes an automated and intelligent planting device for Polygonum multiflorum, which can simultaneously sterilize the soil during the planting process. The device is simple and convenient to use, and no manual intervention is required during soil turning and sterilization. It effectively improves the efficiency and effect of sterilization and disinfection, and greatly optimizes the growth environment of Polygonum multiflorum. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1, refer to Figure 1-7 A Polygonum multiflorum planting device includes a box body 1, a partition 2 inserted into the middle of the box body 1, a planting section 11 above the partition 2, and a drainage section 12 below the partition 2. The planting section 11 is equipped with an ultraviolet component 3 and a cylindrical component 4 that integrates sterilization, watering, soil loosening and heating, and extends through the planting section 11 to the outside of the box body 1. The drainage section 12 is equipped with a negative pressure drainage structure 5.

[0039] The cylindrical assembly 4 is provided in two sets, located on both sides of the ultraviolet assembly 3. The cylindrical assembly 4 includes an assembly port 131 on the side of the main body 1. An assembly groove 132 is provided on the inner wall of the main body 1, which is opposite to the assembly port 131. A rotating outer cylinder 41 is inserted between the assembly port 131 and the assembly groove 132. A fixed inner cylinder 42 is detachably inserted into the rotating outer cylinder 41. A heating rod, ozone tube, or ultraviolet lamp tube is inserted into the fixed inner cylinder 42. The outer circumference of the rotating outer cylinder 41 is provided with several through grooves 411 that communicate with the interior of the rotating outer cylinder 41. A stirring rod 44 is inserted into each of the through grooves 411. The fixed inner cylinder 42 has an arc-shaped conical structure at one end facing the through groove 411, and the stirring rod 44 has an arc-shaped hemispherical structure at one end facing the through groove 411. The end of the arc-shaped conical structure of the fixed inner cylinder 42 contacts the end of the arc-shaped hemispherical structure of the stirring rod 44, which facilitates the fixed inner cylinder 42 to push the stirring rod 44 out of the through groove 411 while inserting into the rotating outer cylinder 41. The limiting plate 441 is used to prevent the stirring rod 44 from disengaging from the through groove 411, so that the end of the stirring rod 44 with the limiting plate 441 is restricted within the through groove 411.

[0040] A limiting plate 441 is provided on the outer peripheral surface of the insertion point between the stirring rod 44 and the through groove 411, and the diameter of the opening end of the through groove 411 is smaller than the diameter of the limiting plate 441.

[0041] The rotating outer cylinder 41 has several limiting grooves 45 along its length. The fixed inner cylinder 42 has limiting blocks 46 on its outer side that are inserted into the limiting grooves 45. The fixed inner cylinder 42 is a hollow inner cylinder with internal water injection holes 421 on its surface corresponding to the through grooves 411 and communicating with the hollow interior of the fixed inner cylinder 42. The stirring rod 44 has a hollow, through-hole external water injection hole 442 inside. This allows the internal water injection hole 421 of the fixed inner cylinder 42 to communicate with the through grooves 411 and with the external water injection hole 442 of the stirring rod 44. This interconnection of the three holes enables the direct introduction of water, fertilizer solution, bactericide solution, temperature and airflow, oxygen, ultraviolet light, ozone, and other substances required for treatment into the planting soil, which is highly effective, flexible, and practical.

[0042] The open end of the fixed inner cylinder 42 can be connected to the external water injection device through conventional pipe connection methods, such as threaded connection, flange connection, welding, grooved connection (clamp connection), compression fitting connection, press-fit connection, hot melt connection, socket connection, etc., without being limited to one method.

[0043] Both of the two rotating outer cylinders 41 are connected to one end of the assembly port 131 with gear 47. A chain 48 is connected between the two gears 47. A motor 49 is provided on one side of the box body 1. A gear 491 is connected to the output shaft of the motor 49. The gear 491 is connected to the chain 48. The motor 49 drives the chain 48 to move and drive the rotating outer cylinder 41 to rotate. Multiple stirring rods 44 arranged externally can loosen or turn the soil inside the plant.

[0044] The ultraviolet component 3 includes a housing body 1 with an assembly port 141 on the side opposite to the first assembly port 131. The housing body 1 has an assembly groove 142 corresponding to the second assembly port 141 inside. A transparent sleeve 31 is inserted between the second assembly port 141 and the assembly groove 142. An ozone tube 32 is located in the center of the transparent sleeve 31. Several vents 33 communicating with the interior of the transparent sleeve 31 are located on the outer circumference of the transparent sleeve 31. Several ultraviolet lamps 34 are arranged in a ring around the inner sidewall of the transparent sleeve 31 with the center as the axis. The ozone tube 32 is connected to an ozone generator (not shown in the accompanying drawings, representing existing mature technology, and not considered the only one). The vents 33 allow ozone to enter the soil, and the transparent sleeve 31 facilitates the irradiation of the soil by the ultraviolet lamps 34.

[0045] Assembly port three 151 is provided on the box body 1 below assembly port two 141. Assembly slot three 152 is provided inside the box body 1, corresponding to assembly port three 151. The partition plate 2 is inserted and installed between assembly port three 151 and assembly slot three 152. The upper surface of the partition plate 2 is provided with several guide strips 21 distributed in a wavy pattern. The partition plate 2 is also provided with several guide grooves 22 connecting the planting part 11 and the drainage part 12. The guide grooves 22 are provided with filter screens. The filter screens are used to prevent soil from clogging the guide grooves 22 and to prevent soil from falling into the drainage part 12. The guide strips 21 facilitate the diversion of waste liquid, allowing the waste liquid in the soil to flow into the guide grooves 22.

[0046] The negative pressure drainage structure 5 includes a lower bottom surface inside the main body 1, which is an inclined surface. A negative pressure pipe 51 is provided on one side of the lower end of the inclined surface, extending out of the main body 1 and connected to a negative pressure generator. A temperature sensor 6 and a humidity sensor 7 are provided on the main body 1, with the probe of the humidity sensor 7 extending into the main body 1. The negative pressure generator is not shown in the attached drawings. Negative pressure generators are common devices on the market and will not be described in detail here.

[0047] This device also includes an external controller, which is connected to the water injection device, heating rod, ozone tube, ultraviolet lamp, motor, ozone generator, temperature sensor, humidity sensor, and negative pressure control unit. It uses existing circuit electronic connection control principles and employs a controller and set control programs to automatically and intelligently control the planting of Polygonum multiflorum, making it very suitable.

[0048] The above-mentioned Polygonum multiflorum planting device can be used as a soil heating device, a soil fungal treatment device, or a soil loosening device.

[0049] In Example 2, based on Example 1, the fixed inner cylinder 42 of the present invention can be selectively connected to an ozone tube, an ultraviolet tube, or a heating rod. Depending on the soil treatment requirements, multiple fixed inner cylinders 42 can be connected to different functional tubes to create a variety of different combinations, which is highly flexible.

[0050] This invention achieves automatic soil turning and sterilization by setting up an ultraviolet component 3 and a cylindrical component 4, integrating sterilization, pouring, loosening soil and heating into one, which effectively improves sterilization efficiency. The negative pressure drainage structure 5 is set up to quickly remove waste liquid and prevent waste liquid from accumulating in the soil, thus optimizing the growth environment of Polygonum multiflorum.

[0051] Implementation 3, a sterilization method based on the Polygonum multiflorum planting device as described above, includes the following steps:

[0052] 1) Assemble the UV component 3 and the cylindrical component 4 separately, and pass through the planting part 11 of the main body 1. Soil is placed in the planting part 11 and Polygonum multiflorum is planted. The UV component 3 is installed on the assembly slot 142 through the assembly port 141. The rotating outer cylinder 41 is installed on the assembly slot 132 through the assembly port 131. The fixed inner cylinder 42 is inserted into the rotating outer cylinder 41. At the same time, the stirring rod 44 extends out of the through slot 411. Connect the various electronic components to the controller.

[0053] 2) Soil moisture is detected by humidity sensor 7. When the moisture level is lower than the planting requirements, nutrient solution and water can be injected into the soil through the inner water channel 421 and outer water channel 442 of the fixed inner cylinder 42. This ensures that the water or nutrient solution is fully absorbed into the soil without excessive watering, which could lead to fungal growth. A diluted solution for killing Fusarium oxysporum or other fungi can be injected as needed. Soil temperature is detected by temperature sensor 6. A heating rod can be inserted into the hollow part of the fixed inner cylinder 42 to directly heat and sterilize the soil. The heating rod can adjust the soil planting temperature and further sterilize or inhibit the growth of low-temperature fungi, reducing the use of pesticides. Generally, the temperature should not exceed 45 degrees Celsius during planting. When not planting, the temperature can be increased for sterilization, significantly reducing pesticide use. Alternatively, an ozone tube or ultraviolet lamp can be inserted into the hollow part of the fixed inner cylinder to directly sterilize the soil with ozone and ultraviolet light, offering great flexibility and practicality.

[0054] 3) Waste liquid seeping from the soil flows into the drainage section 12 through the guide channel 22. Since the bottom surface of the drainage section 12 is inclined, the waste liquid is concentrated at the opening of the negative pressure pipe 51 due to gravity. When the negative pressure machine is started, the waste liquid can be discharged out of the drainage section 12 for treatment through the negative pressure pipe 51. This further improves the treatment of wastewater and prevents the growth of bacteria due to excessive water, thus reducing the use of chemical solutions.

[0055] 4) During or after the planting of Polygonum multiflorum, the motor 49 can be started at any time. Through the meshing and linkage of gear 1 47, gear 2 491 and chain 48, the rotating outer cylinder 41 is driven to rotate, which in turn drives the mixing rod 44 to rotate to loosen or turn the soil in the planting part 11.

[0056] 5) During or after the planting period of Polygonum multiflorum, ozone and ultraviolet light can be generated through ozone tube 32 and ultraviolet lamp tube 34 to sterilize or inhibit the growth of bacteria in the soil. This further reduces the use of pesticide solutions.

[0057] Example 4: A method for planting Polygonum multiflorum, which involves placing soil in the planting section and planting Polygonum multiflorum, and includes the above-mentioned sterilization method based on the Polygonum multiflorum planting device, and can realize an automatic and intelligent planting.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.

A sterilization method for a Polygonum multiflorum planting device based on a cylindrical component disposed in the planting section as described in any one of claims 1-5, characterized in that, The steps include the following: 1) Assemble the UV component (3) and the cylindrical component (4) respectively, and pass through the planting part (11) of the main body of the box (1). Soil is placed in the planting part (11) and Polygonum multiflorum is planted. 2) Soil moisture is detected by humidity sensor (7). When the moisture is lower than the planting requirements, nutrient solution and water can be injected into the soil through the inner water channel (421) and outer water channel (442) of the fixed inner cylinder (42). During the process, a suitable amount of diluted medicine for killing Fusarium oxysporum or other fungi can be injected. The soil temperature is detected by temperature sensor (6). The heating rod is inserted into the hollow part of the fixed inner cylinder (42) to directly heat and sterilize the soil. Alternatively, the ozone tube or ultraviolet lamp tube is inserted into the hollow part of the fixed inner cylinder (42) to directly sterilize the soil. 3) The waste liquid seeping from the soil flows into the drainage section (12) through the guide channel (22). Since the bottom surface of the drainage section (12) is inclined, the waste liquid is concentrated at the opening of the negative pressure pipe (51) due to gravity. When the negative pressure machine is started, the waste liquid can be discharged out of the drainage section (12) through the negative pressure pipe (51) for treatment. 4) During or after the planting of Polygonum multiflorum, the motor (49) can be started at any time. Through the meshing and linkage of gear one (47), gear two (491) and chain (48), the rotating outer cylinder (41) is driven to rotate, which in turn drives the mixing rod (44) to rotate to loosen the soil in the planting part (11). 5) During or after the planting of Polygonum multiflorum, ozone can be generated by ozone tube (32) and ultraviolet lamp tube (34) and ultraviolet light can be emitted to sterilize the fungi in the soil or inhibit the growth of bacteria.

7. A method for cultivating Polygonum multiflorum, characterized in that, A planting method that includes the sterilization method based on the Polygonum multiflorum planting device as described in claim 6.
