Description

Technical Field

[0001] This invention relates to the field of soilless cultivation technology for potato seed culture, specifically to a soilless cultivation production device for potato seed culture and its application. Background Technology

[0002] Potato seed stock refers to "elite seeds" used to produce seed potatoes and first-grade seed potatoes. They are characterized by genetic stability, high purity, and freedom from viral infection. Produced through asexual reproduction, they effectively maintain the genetic characteristics of the parent plant, ensuring varietal purity and consistency, and providing a reliable genetic basis for subsequent seed potato production and field planting. Chinese Patent Publication No. CN112106636A discloses a "High-Efficiency Subsurface Irrigation Method and Cultivation Facilities for Potato Seed Stock," which describes a method where, after the virus-free seedlings have been fully planted, the microcomputer controller is activated again to supply nutrient solution to the main irrigation pipe and capillary irrigation pipes via a pressure pump, supply pipeline, and solenoid valve. When the required amount is reached, the liquid detector and liquid signal line feed back to the microcomputer controller. The microcomputer controller then adjusts the solenoid valve intermittently according to the growth requirements of the virus-free seedlings, supplying nutrient solution according to the growth needs of the virus-free seedlings. This forms a highly efficient, automatic, soilless cultivation system for virus-free original seed potatoes, improving seed potato quality through soilless cultivation. The seedlings are planted in the cultivation substrate of the cultivation pool, maintaining a certain distance between the seedlings on the cultivation substrate and the bottom of the cultivation pool. The microcomputer controller controls the supply of nutrient solution, which is supplied periodically through drip irrigation.

[0003] Existing soilless cultivation production equipment and its application for potato seed stock have structural design flaws. These flaws include: the atomized nutrient solution has low viscosity and is prone to evaporation or dripping, leading to insufficient nutrition for the potato seed stock roots; and the nutrient solution is wasted because it flows out of the device after spraying the seed stock. Summary of the Invention

[0004] This invention provides a soilless cultivation production device for potato seed stock and its application, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a soilless cultivation production device for potato seed stock, comprising a base, a threaded lifting device fixedly connected to the top of the base near its edge, a cultivation platform fixedly connected to the top of the threaded lifting device, and further comprising: A protective component is fixedly installed on the bottom of the inner side of the cultivation platform, and the top of the protective component is used for limiting and supporting the original potato seedlings. A nutrient supply mechanism is fixedly installed at the output end of a screw lifter. The nutrient supply mechanism is used to hold the thickened nutrient solution and to agitate and mix the nutrient solution. The nutrient circulation mechanism is fixedly installed on the top of the base and positioned below the nutrient supply mechanism. This mechanism is used for purifying and transporting the thickened nutrient solution. In the prior art, a nozzle is installed near the root of the potato seed plant, connected to a water pipe. The nutrient solution is sprayed onto the root of the potato seed plant by periodically opening the nozzle. However, this nutrient solution has a low concentration, making it difficult for the solution to adhere to the root and continuously supply nutrients. Furthermore, the low viscosity of the nutrient solution easily evaporates or drips onto the ground, leading to malnutrition in the potato seed plant. The nutrient supply mechanism includes a liquid storage tank, which is fixedly installed at the output end of a screw lifter. A lead screw slide is fixedly connected to the surface of the liquid storage tank, and an electric turntable is fixedly connected to the output end of the lead screw slide. A scraping assembly is fixedly connected to the output end of the electric turntable. The scraping assembly is used to agitate the thickening nutrient solution and promote its drainage. If the thickening nutrient solution is sprayed using the existing nozzle atomization method, the thickening nutrient solution is prone to sticking and clogging due to the long length of the delivery pipe. At the same time, compared with nozzle spraying, this device makes the nutrient solution more evenly distributed on the root surface of the potato seed by immersion.

[0006] Preferably, a plastic film frame is fixedly connected to the edge of the cultivation platform, and a fixing rod is fixedly connected to the bottom of the cultivation platform. A magnetic ring is slidably connected to the surface of the fixing rod, and the fixing rod is magnetic.

[0007] Preferably, the protective component includes a limiting plate, which is fixedly installed on the top of the cultivation platform, and a fixing ring is fixedly connected to the bottom of the limiting plate. The number of limiting plates is set to multiple.

[0008] Preferably, the cultivation platform has a circular hole near the limiting plate, and the protective component also includes a spring, the top of which is fixedly installed at the bottom of the fixing ring, and the pitch of the spring varies linearly.

[0009] Preferably, the nutrient supply mechanism further includes an extension tube, which is fixedly installed at the bottom of the liquid storage shell. A control valve is fixedly connected to the inner side of the extension tube. The liquid storage shell is filled with thickened nutrient solution. When the liquid storage shell moves upward, the screw slide drives the electric turntable to move to a position near the edge of the liquid storage shell to prevent the original seed roots from being disturbed when submerged in the nutrient solution. When the liquid storage shell moves downward to a position directly above the nutrient circulation mechanism, the viscous nutrient solution can continuously supply nutrients until the next immersion in the nutrient solution. The control valve is opened, and the screw slide drives the connecting plate to move back and forth inside the liquid storage shell. The scraper promotes the flow of the thickened nutrient solution to the control valve.

[0010] Preferably, the scraping assembly includes a connecting plate, the end face of which is fixedly installed at the output end of the electric turntable, and a scraper is fixedly connected to the middle of the surface of the connecting plate.

[0011] Preferably, the scraping assembly further includes a gate opener, which is fixedly installed on the surface of the connecting plate near the edge. The screw at the output end of the gate opener is rotatably connected to a pusher bar, and a slide bar is fixedly connected to the surface of the pusher bar.

[0012] Preferably, the nutrient circulation mechanism includes a circulation box, which is fixedly installed on the top of the base. A U-shaped cross-section shell is fixedly connected to the top of the circulation box, and a top pipe is fixedly connected to the top of the U-shaped cross-section shell. An on / off valve is rotatably connected to the end face of the U-shaped cross-section shell. The inside of the liquid storage shell contains thickened nutrient solution. The potato seedlings are positioned above the protective components, while the roots of the potato seedlings extend to the bottom of the cultivation platform. The upward and downward movement of the liquid storage shell allows the roots of the seedlings to be submerged in a layer of thickened nutrient solution. Nutrient solution dripping down the roots is collected inside the liquid storage shell for reuse, avoiding waste of nutrient solution. Each submersion will result in impurities in the nutrient solution inside the liquid storage shell.

[0013] Preferably, the nutrient circulation mechanism further includes an arc-shaped filter screen, which is fixedly connected to the bottom of the U-shaped cross-section shell. A drive motor is fixedly connected to the surface of the U-shaped cross-section shell, and a spiral rod is fixedly connected to the output end of the drive motor. A flow guiding component is fixedly connected to the lower part of the surface of the circulation tank.

[0014] Preferably, the flow guiding assembly includes a water pump, which is fixedly installed below the surface of the circulation tank. The output end of the water pump is fixedly connected to a fixed pipe, and the top end of the fixed pipe is fixedly connected to a rotating sealing ring. The connecting plate rotates under the drive of the electric turntable. As the connecting plate moves horizontally and flips, the scraper effectively increases the scrapable area of ​​the inner side of the liquid storage shell. The pusher strip scrapes away the nutrient solution deposited on the surface of the scraper under the push of the screw. The openings on the surface of the pusher strip can effectively promote the fall of the liquid, so that the nutrient solution is guided into the interior of the U-shaped cross-section shell with maximum efficiency. The arc-shaped filter screen intercepts impurities inside the nutrient solution.

[0015] Preferably, the flow guiding assembly further includes a hollow motor, the inner side of which is fixedly installed above the surface of the fixed pipe, and the output end of the hollow motor is fixedly connected to a rotating pipe.

[0016] The application of a soilless cultivation production device for potato seed stock includes the following steps: Step 1: Nutrient solution supply. The potato seedlings are positioned above the protective components, while the roots of the potato seedlings extend to the bottom of the cultivation platform. Nutrient solution with a certain viscosity is delivered into the interior of the storage tank. The screw slide drives the electric turntable to move back and forth, so that the thickened nutrient solution is stirred evenly. The screw lifter drives the storage tank to move upward. The upward movement of the storage tank allows the roots of the potato seedlings to be immersed in the interior of the nutrient solution. As the storage tank moves downward, a layer of viscous nutrient solution adheres to the surface of the roots of the potato seedlings. Step 2: Scraping. The storage tank moves down to the position directly above the nutrient circulation mechanism, the control valve is opened, and the screw slide moves the connecting plate back and forth inside the storage tank. The scraper promotes the flow of thickened nutrient solution to the control valve. When the connecting plate moves closer to the inside of the storage tank and away from the control valve, the electric turntable drives the connecting plate to flip, the hoist drives the screw to move downward, and the pusher bar moves up and down along the scraper under the drive of the screw and slide, thereby scraping off the nutrient solution adhering to the surface of the scraper. Step 3: Purification. The upward and downward movement of the storage tank allows the roots of the original seed to be submerged in a layer of thickened nutrient solution. The nutrient solution dripping down the roots will be collected inside the storage tank for the next use. The bottom end of the extension tube extends into the inside of the top tube. The control valve is opened, and the nutrient solution flows through the extension tube to the position of the arc-shaped filter. The nutrient solution flows through the arc-shaped filter into the inside of the circulation box for temporary storage. Step 4: Recycling. The arc-shaped filter screen intercepts impurities inside the nutrient solution. When a large amount of impurities accumulate, the drive motor rotates the screw rod. The screw rod's spiral lifting force guides the deposited impurities to the opening and closing valve for discharge. The hollow motor drives the rotating tube to rotate, ensuring that the liquid storage tank is not disturbed by the rotating tube when it moves up and down. The water pump transports the nutrient solution temporarily stored inside the circulation tank to the solid pipe and the rotating tube.

[0017] This invention provides a soilless cultivation production device for potato seed stock and its application. It has the following beneficial effects: 1. The soilless cultivation production device for potato seed stock and its application involves delivering a nutrient solution with a certain viscosity into the interior of the storage tank. A screw slide drives an electric turntable to move back and forth, ensuring that the thickened nutrient solution is evenly mixed. A screw lifter moves the storage tank upwards, immersing the roots of the potato seed stock in the nutrient solution. As the storage tank moves downwards, a layer of viscous nutrient solution adheres to the surface of the potato seed stock roots. This solves the problem of insufficient nutrition for the potato seed stock roots due to the low viscosity of the atomized nutrient solution, which is prone to evaporation or dripping.

[0018] 2. The soilless cultivation production device for potato seed stock and its application: The root of each potato seed stock is wrapped by a spring. The spring prevents the roots from tangling when submerged in the nutrient solution. The upper part of the root stock has a larger diameter, correspondingly, the pitch of the spring is smaller at the upper position and larger at the lower position. This prevents the roots from extending outside the spring when the nutrient solution tank moves upward. The diameter at the upper position of the spring is larger than that at the lower position. When the roots of the seed stock are submerged in the nutrient solution tank, the height of the spring after contraction is smaller, resulting in a larger submerged area of ​​the roots and a more uniform distribution of nutrient solution, thus improving the cultivation efficiency of potato seed stock.

[0019] 3. The soilless cultivation production device for potato seed stock and its application: When the connecting plate moves closer to the inner side of the liquid storage tank and away from the control valve, the electric turntable drives the connecting plate to rotate, the gate opener drives the screw to move downward, and the liquid pusher moves up and down along the scraper plate under the drive of the screw and the slide bar, thereby scraping off the nutrient solution adhering to the surface of the scraper plate. With the rotation of the connecting plate, the adhesion of the thickened nutrient solution is prevented from causing bacterial growth.

[0020] 4. The soilless cultivation production device for potato seed stock and its application: After a period of use, the bottom end of the extension pipe extends into the interior of the top pipe, the control valve opens, and the nutrient solution flows through the extension pipe to the position of the arc-shaped filter screen. The nutrient solution flows through the arc-shaped filter screen into the interior of the circulation tank for short-term storage. Then, the flow guiding component guides the nutrient solution back into the interior of the storage tank for use. This solves the problem of a large amount of nutrient solution being wasted when the seed stock is sprayed by the atomizer and then flows out of the device after spraying.

[0021] 5. The soilless cultivation production device for potato seed stock and its application: When there is a lot of impurities, the drive motor drives the screw to rotate. The screw's helical lifting force guides the deposited impurities to the opening and closing valve for discharge, making the overall automation level of the potato seed stock cultivation device higher. The hollow motor drives the rotating tube to rotate, so that the liquid storage tank is not disturbed by the rotating tube when it moves up and down. The water pump transports the nutrient solution temporarily stored in the circulation tank to the fixed tube and the rotating tube. The nutrient solution is transported to the inside of the liquid storage tank, making the utilization efficiency of the nutrient solution higher. Attached Figure Description

[0024] 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.

[0025] First embodiment: as follows Figures 1-5 As shown, the present invention provides a technical solution: a soilless cultivation production device for potato seed stock, including a base 1, a threaded lifting device 2 fixedly connected to the top of the base 1 near the edge, a cultivation platform 3 fixedly connected to the top of the threaded lifting device 2, a plastic film frame 42 fixedly connected to the edge of the cultivation platform 3, a fixing rod 41 fixedly connected to the bottom of the cultivation platform 3, a magnetic ring 43 slidably connected to the surface of the fixing rod 41, the fixing rod 41 being magnetic, and further comprising: Protective component 5 is fixedly installed on the bottom of the inner side of the cultivation platform 3, and the top of the protective component 5 is used for limiting and supporting the potato seedlings. The nutrient supply mechanism 6 is fixedly installed at the output end of the screw lifter 2. The nutrient supply mechanism 6 is used to hold the thickened nutrient solution and to agitate and mix the nutrient solution. Nutrient circulation mechanism 7 is fixedly installed on the top of base 1 and located below nutrient supply mechanism 6. Nutrient circulation mechanism 7 is used for the purification and transportation of thickened nutrient solution. The nutrient supply mechanism 6 includes a liquid storage tank 61, which is fixedly installed at the output end of the screw lifter 2. A screw slide 64 is fixedly connected to the surface of the liquid storage tank 61. An electric turntable 65 is fixedly connected to the output end of the screw slide 64. A scraping component 66 is fixedly connected to the output end of the electric turntable 65. The scraping component 66 is used for stirring the thickened nutrient solution and for pushing the liquid out. The nutrient supply mechanism 6 also includes an extension tube 62, which is fixedly installed at the bottom of the liquid storage shell 61, and a control valve 63 is fixedly connected to the inner side of the extension tube 62.

[0026] In use, the magnetic ring 43 slides up and down on the surface of the fixed rod 41 to control the raising and lowering of the heat-insulating plastic film frame 42. In existing technology, a nozzle is installed near the root of the potato seed, connected to a water pipe. Nutrient solution is sprayed onto the root of the potato seed by periodically opening the nozzle. However, this nutrient solution has a low concentration, making it difficult for the solution to adhere to the root and continuously supply nutrients. Furthermore, the low viscosity of the nutrient solution easily evaporates or drips onto the ground, leading to malnutrition of the potato seed. This device will incorporate a certain... The viscous nutrient solution is delivered into the storage tank 61. The screw slide 64 drives the electric turntable 65 to move back and forth, so that the thickened nutrient solution is stirred evenly. The screw lift 2 drives the storage tank 61 to move upward. The upward movement of the storage tank 61 allows the roots of the potato seed to be submerged in the nutrient solution. As the storage tank 61 moves downward, a layer of viscous nutrient solution adheres to the surface of the potato seed roots, which solves the problem of insufficient nutrition for the roots of the potato seed due to the low viscosity of the atomized nutrient solution, which is easy to evaporate or drip.

[0027] Second embodiment: as follows Figure 3 , Figure 4 , Figure 5 As shown, the protective component 5 includes a limiting plate 51, which is fixedly installed on the top of the cultivation platform 3. A fixing ring 52 is fixedly connected to the bottom of the limiting plate 51. Multiple limiting plates 51 are provided. A round hole 54 is opened on the cultivation platform 3 near the limiting plate 51. The protective component 5 also includes a spring 53, the top of which is fixedly installed on the bottom of the fixing ring 52. The pitch of the spring 53 changes linearly. The liquid storage tank 61 is fixedly installed at the output end of the threaded lifting device 2. A lead screw slide 64 is fixedly connected to the surface of the liquid storage tank 61. An electric turntable 65 is fixedly connected to the output end of the lead screw slide 64. A scraping assembly 66 is fixedly connected to the output end of the electric turntable 65. The scraping assembly 66 is used for stirring the thickening nutrient solution and pushing the liquid discharge. The nutrient supply mechanism 6 also includes an extension tube 62. The extension tube 62 is fixedly installed at the bottom of the liquid storage tank 61. A control valve 63 is fixedly connected to the inner side of the extension tube 62.

[0028] When in use, if the thickened nutrient solution is sprayed using existing nozzle atomization methods, the long delivery pipe can easily cause the thickened nutrient solution to become viscous and clogged. Compared to nozzle spraying, this device uses an immersion method to ensure a more even distribution of the nutrient solution on the root surface of the potato seed stock. Each potato seed stock root is wrapped by a spring 53. The spring 53 prevents the roots from tangling together when immersed in the nutrient solution. The upper root diameter of the seed stock is larger, correspondingly, the pitch of the upper part of the spring 53 is smaller, while the pitch of the lower part of the spring 53 is larger. This prevents the seed stock roots from extending beyond the spring 53 when the reservoir shell 61 moves upward. The diameter of the upper part of the spring 53 is larger than that of the lower part. When the seed stock roots are immersed inside the reservoir shell 61, the height of the spring 53 after contraction is smaller, resulting in a larger immersion area for the seed stock roots, a more even distribution of the nutrient solution, and higher cultivation efficiency for the potato seed stock.

[0029] Third embodiment: as follows Figure 5 , Figure 6 As shown, the scraping assembly 66 includes a connecting plate 661, the end face of which is fixedly installed at the output end of the electric turntable 65. A scraper blade 662 is fixedly connected to the middle of the surface of the connecting plate 661. The scraping assembly 66 also includes a gate hoist 663, which is fixedly installed on the surface of the connecting plate 661 near the edge. A pusher bar 664 is rotatably connected to the screw at the output end of the gate hoist 663. A slide bar 665 is fixedly connected to the surface of the pusher bar 664.

[0030] In use, the storage tank 61 is filled with thickened nutrient solution. When the storage tank 61 moves upward, the screw slide 64 drives the electric turntable 65 to move the storage tank 61 to a position near the edge to prevent the original seed roots from being disturbed when submerged in the nutrient solution. When the storage tank 61 moves downward to a position directly above the nutrient circulation mechanism 7, the viscous nutrient solution can continuously supply nutrients until the next immersion in the nutrient solution. The control valve 63 is opened, and the screw slide 64 drives the connecting plate 661 to reciprocate inside the storage tank 61. The scraper plate 662 moves to facilitate the flow of thickened nutrient solution to the control valve 63. When the connecting plate 661 moves closer to the inside of the storage tank 61 and away from the control valve 63, the electric turntable 65 drives the connecting plate 661 to rotate. The hoist 663 drives the screw to move downward. The pusher bar 664 moves up and down along the scraper plate 662 under the drive of the screw and the slide bar 665, thereby scraping off the nutrient solution adhering to the surface of the scraper plate 662. As the connecting plate 661 rotates, it prevents the thickened nutrient solution from adhering and causing bacterial growth.

[0031] Fourth embodiment: as Figure 5 , Figure 7 , Figure 8As shown, a lead screw slide 64 is fixedly connected to the surface of the liquid storage shell 61. An electric turntable 65 is fixedly connected to the output end of the lead screw slide 64. A scraping assembly 66 is fixedly connected to the output end of the electric turntable 65. The scraping assembly 66 is used for stirring the thickening nutrient solution and pushing the liquid out. The nutrient supply mechanism 6 also includes an extension tube 62. The extension tube 62 is fixedly installed at the bottom of the liquid storage shell 61. A control valve 63 is fixedly connected to the inner side of the extension tube 62. The nutrient circulation mechanism 7 includes a circulation box 71, which is fixedly installed on the top of the base 1. A U-shaped cross-section shell 72 is fixedly connected to the top of the circulation box 71. A top pipe 73 is fixedly connected to the top of the U-shaped cross-section shell 72. An on / off valve 77 is rotatably connected to the end face of the U-shaped cross-section shell 72. The nutrient circulation mechanism 7 also includes an arc-shaped filter screen 74, which is fixedly joined to the bottom of the U-shaped cross-section shell 72. A drive motor is fixedly connected to the surface of the U-shaped cross-section shell 72. A spiral rod 75 is fixedly connected to the output end of the drive motor. A flow guide assembly 76 is fixedly connected to the lower part of the surface of the circulation box 71.

[0032] During use, the storage tank 61 contains thickened nutrient solution. The potato seedlings are positioned above the protective component 5, while the roots of the potato seedlings extend to the bottom of the cultivation platform 3. The upward and downward movement of the storage tank 61 submerges the roots of the seedlings in a layer of thickened nutrient solution. The nutrient solution dripping down the roots is collected inside the storage tank 61 for reuse, avoiding waste. Each submersion introduces impurities into the nutrient solution inside the storage tank 61. After a period of use, the bottom end of the extension tube 62 extends into the top tube 73, and the control valve 63 opens. The nutrient solution flows through the extension tube 62 to the arc-shaped filter 74, and then flows through the arc-shaped filter 74 into the circulation box 71 for temporary storage. Subsequently, the guide component 76 guides the nutrient solution back into the storage tank 61 for use. This solves the problem of significant waste caused by the nutrient solution flowing out of the device after spraying the seedlings with an atomizer.

[0033] Fifth embodiment: as follows Figure 6 , Figure 9 As shown, the end face of the connecting plate 661 is fixedly installed at the output end of the electric turntable 65. A scraper 662 is fixedly connected to the middle of the surface of the connecting plate 661. The scraper assembly 66 also includes a gate opener 663. The gate opener 663 is fixedly installed on the surface of the connecting plate 661 near the edge. A pusher bar 664 is rotatably connected to the screw at the output end of the gate opener 663. A slide bar 665 is fixedly connected to the surface of the pusher bar 664. The circulation box 71 is fixedly installed on the top of the base 1. A U-shaped cross-section shell 72 is fixedly connected to the top of the circulation box 71. A top pipe 73 is fixedly connected to the top of the U-shaped cross-section shell 72. An opening and closing valve 77 is rotatably connected to the end face of the U-shaped cross-section shell 72. The nutrient circulation mechanism 7 also includes an arc-shaped filter screen 74. The arc-shaped filter screen 74 is fixedly joined to the bottom of the U-shaped cross-section shell 72. A drive motor is fixedly connected to the surface of the U-shaped cross-section shell 72. A spiral rod 75 is fixedly connected to the output end of the drive motor. A flow guiding component 76 is fixedly connected to the lower part of the surface of the circulation box 71. The flow guiding assembly 76 includes a water pump 761, which is fixedly installed below the surface of the circulation tank 71. The output end of the water pump 761 is fixedly connected to a fixed pipe 762, and the top end of the fixed pipe 762 is fixedly connected to a rotating sealing ring 763. The flow guiding assembly 76 also includes a hollow motor 764, the inner side of which is fixedly installed above the surface of the fixed pipe 762. The output end of the hollow motor 764 is fixedly connected to a rotating pipe 765.

[0034] In use, the connecting plate 661 rotates under the drive of the electric turntable 65. As the connecting plate 661 moves horizontally and flips, the scraper plate 662 effectively increases the scrapable area on the inner side of the liquid storage shell 61. The pusher bar 664, pushed by the screw, scrapes away the nutrient solution deposited on the surface of the scraper plate 662. The openings on the surface of the pusher bar 664 effectively promote the falling of the liquid, so that the nutrient solution is guided into the interior of the U-shaped cross-section shell 72 with maximum efficiency. The arc-shaped filter screen 74 intercepts impurities inside the nutrient solution. When a large amount of impurities are deposited... At this time, the drive motor drives the screw rod 75 to rotate. The screw rod 75's spiral lifting force causes the deposited impurities to be guided to the on / off valve 77 for discharge, making the overall automation level of the potato seed cultivation device higher. The hollow motor 764 drives the rotating tube 765 to rotate, so that the liquid storage tank 61 is not disturbed by the rotating tube 765 when it moves up and down. The water pump 761 transports the nutrient solution temporarily stored in the circulation tank 71 to the fixed tube 762 and the rotating tube 765. The nutrient solution is transported to the inside of the liquid storage tank 61, making the nutrient solution utilization efficiency higher.

[0035] Sixth embodiment: as follows Figure 1-9 As shown, the application of a soilless cultivation production device for potato seed stock includes the following steps: Step 1: Nutrient solution supply. The potato seedlings are positioned above the protective component 5, while the roots of the potato seedlings extend to the lower part of the cultivation platform 3. Nutrient solution with a certain viscosity is delivered to the interior of the storage tank 61. The screw slide 64 drives the electric turntable 65 to move back and forth, so that the thickened nutrient solution is stirred evenly. The screw lift 2 drives the storage tank 61 to move upward. The upward movement of the storage tank 61 allows the roots of the potato seedlings to be immersed in the interior of the nutrient solution. As the storage tank 61 moves downward, a layer of viscous nutrient solution adheres to the surface of the roots of the potato seedlings. Step 2: Drainage. The storage tank 61 moves down to the position directly above the nutrient circulation mechanism 7, the control valve 63 is opened, and the screw slide 64 drives the connecting plate 661 to move back and forth inside the storage tank 61. The scraper 662 promotes the flow of the thickened nutrient solution to the control valve 63. When the connecting plate 661 moves closer to the inside of the storage tank 61 and away from the control valve 63, the electric turntable 65 drives the connecting plate 661 to flip, the gate opener 663 drives the screw to move downward, and the pusher bar 664 moves up and down along the scraper 662 under the drive of the screw and slide 665, thereby scraping off the nutrient solution adhering to the surface of the scraper 662. Step 3: Purification and impurity removal. The upward and downward movement of the liquid storage shell 61 allows the roots of the potato seed to be submerged in a layer of thickened nutrient solution. The nutrient solution dripping down the roots will be collected inside the liquid storage shell 61 for the next use. The bottom end of the extension tube 62 extends into the inside of the top tube 73. The control valve 63 is opened, and the nutrient solution flows through the extension tube 62 to the position of the arc-shaped filter screen 74. The nutrient solution flows through the arc-shaped filter screen 74 into the inside of the circulation box 71 for temporary storage. Step 4: Recycling. The arc-shaped filter 74 intercepts impurities inside the nutrient solution. When a large amount of impurities accumulate, the drive motor drives the screw rod 75 to rotate. The screw rod 75's spiral lifting force guides the deposited impurities to the on / off valve 77 for discharge. The hollow motor 764 drives the rotating tube 765 to rotate, ensuring that the storage tank 61 is not disturbed by the rotating tube 765 when it moves up and down. The water pump 761 transports the nutrient solution temporarily stored inside the circulation tank 71 to the solid pipe 762 and the rotating tube 765. The purified nutrient solution flows back to the inside of the storage tank 61 for reuse.
