Description

Technical Field

[0001] This invention belongs to the field of Paris polyphylla seedling cultivation technology, specifically relating to a seedling cultivation device and method for planting Paris polyphylla yunnanensis. Background Technology

[0002] Paris polyphylla, also known as Yunnan Paris polyphylla, is a traditional and precious Chinese medicinal herb listed in the Pharmacopoeia of the People's Republic of China. It is renowned as a "plant antibiotic" due to its unique medicinal value. The medicinal part is its dried rhizome, which is slightly cold in nature, bitter in taste, and slightly toxic. Its core functions are clearing heat and detoxifying, reducing swelling and relieving pain, cooling the liver and calming the nerves. It is commonly used to treat boils, carbuncles, sore throat, snake and insect bites, and traumatic injuries. Modern research has shown that its main active ingredient is steroidal saponins, in addition to polysaccharides, flavonoids, and other compounds. Modern pharmacological studies have confirmed that it has multiple effects, including anti-tumor, hemostatic, anti-inflammatory, and immunomodulatory effects. It is one of the main raw materials for many well-known traditional Chinese medicines such as "Yunnan Baiyao" and "Gongxue Ning".

[0003] Due to its long growth cycle and the over-harvesting of wild resources, Paris polyphylla is becoming increasingly precious. In order to ensure normal supply, artificial cultivation of Paris polyphylla is increasingly used to fill the demand for wild Paris polyphylla. In the current technology, when artificially cultivating Paris polyphylla, the cultivation cup is a one-piece hard plastic bag or plastic cup. During the later planting and cultivation, the hard plastic bag needs to be cut open to remove the seedling along with the cultivation soil. This method of removing seedlings is inefficient. When removing seedlings from plastic cups, a stick-shaped object is needed to push out the cultivation soil and seedlings from under the plastic cup. This method of removal can easily cause the cultivation soil to collapse, damaging the roots of the Paris polyphylla seedlings and potentially affecting the survival rate of Paris polyphylla. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a seedling device that facilitates the rapid separation of the potting soil and seedlings from the cultivation equipment.

[0005] The technical solution adopted to solve the above technical problems is: a seedling raising device for planting Paris polyphylla, including an external placement box for centralized seedling raising, wherein a plurality of seedling raising device bodies are arranged inside the external placement box, and the plurality of seedling raising device bodies are connected by a limiting mover for controlling the transfer of the seedling raising device bodies.

[0006] Through the above technical solution, the main body of the seedling device is connected and combined using a limiting mover, realizing the synchronous transfer and centralized management of multiple sets of seedling device main bodies. This solves the problems of cumbersome and inefficient operation of individual seedling cups in traditional seedling cultivation. The external placement box provides a relatively uniform environment for seedling cultivation, while the separate support protrusions separate the main body of the seedling device from the inner bottom wall of the external placement box, preventing the bottom of the main body of the seedling device from directly contacting water accumulation. This ensures smooth ventilation and drainage at the bottom of the main body of the seedling device, effectively reducing the risk of root rot of Paris polyphylla seeds or seedlings due to water accumulation. The main body of the seedling device adopts two symmetrically arranged seedling frames to form a cup structure. This detachable design is one of the core innovations of this invention. When it is necessary to remove the seedlings, there is no need to use traditional hard plastic cups. To prevent damage or ejection, simply release the limiting mechanism between the two-way hook and the limiting mover. Then, by rotating the connecting hinge, the two seedling frames can be flipped open to the sides, allowing the nutrient soil and seedlings to fall off naturally. This minimizes damage to the seedling roots and improves the seedling survival rate. The drainage holes on the side walls and bottom of the seedling frames can drain excess water in time, preventing the nutrient soil from becoming too wet. This provides a suitable moisture environment for the germination of Paris polyphylla seeds and the growth of seedlings. The two-way hook and the two-way limiting protrusion on the limiting mover work together to achieve stable positioning of the main body of the seedling device during transfer and cultivation, ensuring the convenience and reliability of the operation. The drainage holes further ensure that no water accumulates inside the external placement box, thus providing good drainage for the entire seedling system.

[0007] The bottom wall of the external placement box is fixedly connected to several evenly distributed separation support protrusions, and several seedling device bodies are placed on the surface of the corresponding separation support protrusions.

[0008] Through the above technical solution, the separation support protrusion plays the role of supporting the main body of the seedling device. At the same time, the separation support protrusion raises the main body of the seedling device by a certain distance, so that an air circulation gap is formed between the bottom of the main body of the seedling device and the bottom wall of the outer placement box. This helps air to flow at the bottom of the main body of the seedling device, promotes the rapid evaporation of water discharged from the drainage holes at the bottom of the seedling frame, further reduces the humidity at the bottom of the main body of the seedling device, provides a more sufficient oxygen environment for the respiration of the roots of Paris polyphylla, and reduces the probability of root diseases.

[0009] Furthermore, the main body of the seedling device includes two symmetrically arranged seedling frames, which form a cup structure. The side walls and bottom of the two seedling frames are provided with a number of evenly distributed hydrophobic through holes for draining excess water.

[0010] Through the above technical solution, the cup structure formed by the two seedling frames provides an independent and suitable space for the cultivation of Paris polyphylla seeds. Each cup structure can be used for seed sowing and management independently, which facilitates precise care for seedlings at different growth stages. The design of drainage holes on the side walls and bottom is particularly crucial. When watering is excessive or the ambient humidity is high, excess water can quickly seep out through these holes, preventing the nutrient soil from being oversaturated for a long time. The size of these drainage holes has been optimized to effectively drain water and prevent nutrient soil particles from being lost with water, ensuring the stability of the nutrient soil structure and maintaining the necessary water and air ratio for seed germination and root growth. At the same time, the drainage holes at the bottom can also prevent seedling roots from rotting due to lack of oxygen caused by prolonged immersion in water, while the drainage holes on the side walls help promote air circulation inside the cup, reducing the risk of mold growth and creating a dry and breathable microenvironment for Paris polyphylla seedlings.

[0011] Furthermore, the two seedling frames are configured with their bottoms flipped upside down, and the bottoms of the two seedling frames are rotatably connected by a rotatable hinge. The sides of the bottoms of the two seedling frames that are close to each other are rounded.

[0012] Through the above technical solution, the rotating connecting hinge provides a stable rotating shaft for the flipping of the two seedling frames, making the opening and closing of the seedling frames smoother and less strenuous. The bottom flipping design ensures that when the main body of the seedling device is opened, the two seedling frames can be smoothly unfolded to both sides with the bottom as the fulcrum, avoiding the problem of uneven force causing the nutrient soil and seedlings to tip over in the traditional seedling taking method. The bottom of the two seedling frames is rounded on the side that is close to each other, which avoids movement interference at the bottom corner when the seedling frames are unfolded.

[0013] Furthermore, two C-shaped bidirectional hooks are fixedly connected to the opposite sides of the upper surfaces of the two seedling frames, and the bidirectional hooks face the same direction. The upper and lower inner walls of the bidirectional hooks are provided with positioning grooves.

[0014] Through the above technical solution, the C-shaped design of the bidirectional hook can stably hook onto the connecting support rod, providing a structural basis for the connection between the seedling device body and the limiting mover. The consistent orientation of the hooks ensures that when multiple seedling device bodies are hooked, they can be neatly arranged, facilitating subsequent centralized transfer and management. The limiting grooves on the inner top and bottom walls of the bidirectional hooks precisely match the bidirectional limiting protrusions on the connecting support rod. This concave-convex interlocking structure, when the seedling device body is hooked onto the limiting mover, whether during the lifting and transfer process (the upper limiting groove matches the bidirectional limiting protrusion) or when placed in the external placement box for cultivation, effectively limits the longitudinal and lateral movement of the seedling device body. This prevents the seedling device body from shaking, falling off, or the seedling frame from accidentally unfolding during movement or cultivation, ensuring the stability and safety of the seedling process. It also provides a convenient operation method for the quick picking, placing, and positioning of the seedling device body.

[0015] Furthermore, the outer wall of the external placement box is provided with several evenly distributed through drainage holes near the lower part, and the highest surface of several through drainage holes is lower than the highest surface of the separation support protrusion.

[0016] Through the above technical solution, the through drainage hole can promptly drain water that has seeped out of the seedling container body or accumulated due to environmental factors in the external placement box, preventing water accumulation inside the box. The design that the highest surface of the through drainage hole is lower than the highest surface of the separation support protrusion ensures that even if there is a small amount of water in the external placement box, it will not submerge the bottom of the seedling container body on the separation support protrusion. This ensures that the seedling container body is always in a relatively dry environment, preventing water from seeping back into the bottom of the seedling container body and affecting the drainage effect, further reducing the possibility of root rot in Paris polyphylla seedlings.

[0017] Furthermore, the limiting mover includes two symmetrically arranged connecting support rods, and a connecting moving column is fixedly connected between the two ends of the two connecting support rods.

[0018] Through the above technical solution, two parallel connecting support rods provide a stable support structure for the main body of the seedling tray, allowing multiple seedling trays to be evenly and stably arranged among them. The connecting movable columns are located at both ends of the connecting support rods, forming a handle-like structure that allows operators to easily lift the entire limiting movable device and the seedling trays attached to it with both hands or one hand. This achieves the overall and convenient transfer of the seedling tray, avoiding the scattering and inefficiency problems associated with traditional single-seedling cup handling. The length of the connecting movable columns is reasonably designed, ensuring both operator comfort and force balance when lifting the device.

[0019] Furthermore, several evenly distributed bidirectional limiting protrusions are fixedly connected to the upper and lower sides of the outer wall of the connecting support rod, and the size and shape of the bidirectional limiting protrusions are consistent with the size and shape of the limiting groove of the bidirectional hook.

[0020] The above technical solution ensures that the size and shape of the bidirectional limiting protrusion and the bidirectional hook limiting groove are consistent, which is the key to achieving precise fitting between the two. When the main body of the seedling device is attached to the connecting support rod via the bidirectional hook, the bidirectional limiting protrusions on the connecting support rod can perfectly engage with the limiting grooves on the inner top wall of the bidirectional hook. When the connecting support rod is lowered, the lower bidirectional limiting protrusion engages with the limiting groove below the bidirectional hook. This design not only fixes the main body of the seedling device vertically to prevent it from sliding up and down, but also restricts the left and right displacement of the main body of the seedling device horizontally, ensuring the neatness and stability of multiple seedling devices on the limiting mover. When transferring the main body of the seedling device, this stable engaging structure can effectively prevent the main body of the seedling device from falling off the limiting mover due to shaking, ensuring the safety of the transfer process. In the cultivation stage, the lower bidirectional limiting protrusion engages with the lower limiting groove, which can prevent the seedling frame from accidentally flipping open, providing a stable cultivation space for the growth of Paris polyphylla seeds and seedlings. Several evenly distributed bidirectional limiting protrusions allow multiple seedling devices to be attached to one limiting mover, realizing batch operation and further improving seedling efficiency.

[0021] A method for cultivating and using a seedling raising device for planting Paris polyphylla includes the following specific operating steps: Step 1. Place two symmetrical seedling frames together, holding them together with one hand, and fill the seedling frames with nutrient soil. Step 2. Hang the two-way hook of the seedling frame filled with nutrient soil on the outside of the connecting support rod of the limiting mover, and push the two-way limiting protrusion at the top of the connecting support rod into the upper limiting groove of the corresponding two-way hook. Step 3. When the corresponding limiting mover is filled with the seedling device body, lift the corresponding connecting moving column, move the corresponding limiting mover and the corresponding seedling device body into the external placement box, place the seedling device body on the separation support protrusion surface, and lower the limiting mover so that the bidirectional limiting protrusion below the limiting mover is engaged in the lower limiting groove of the corresponding bidirectional hook. Step 4. Place Paris polyphylla seeds into the nutrient soil inside the corresponding seedling container for cultivation and planting. Excess water flows out from the drainage holes of the seedling frame and is discharged through the drainage holes of the external box. Step 5. After the seedlings are grown, lift the corresponding connecting moving column with both hands so that the bidirectional limiting protrusion on the top of the connecting support rod is engaged in the limiting groove on the top of the corresponding bidirectional hook, and lift the main body of the seedling device out to place it in the box. Step 6. Remove the limiting mover from the corresponding seedling body position, so that the corresponding bidirectional hook loses its limiting position, and flip the seedling frame to both sides to separate the seedling frame from the nutrient soil, so that the Paris polyphylla seedlings can be separated from the nutrient soil as a whole.

[0022] The beneficial effects of the present invention are as follows: (1) The present invention adopts a detachable seedling frame structure, combined with the design of bidirectional hooks and limiting movers, to achieve the overall and non-destructive separation of Paris polyphylla seedlings and nutrient soil, effectively solving the problem of easy damage to the root system when taking seedlings in traditional seedling devices, significantly improving the survival rate of seedlings, and the centralized treatment of the flip-type seedling frame improves the efficiency of seedling taking. (2) Through the synergistic effect of the external placement box, the separation support protrusion and the drainage through hole and through drainage hole, a well-ventilated and well-drained seedling environment is constructed, effectively reducing the risk of root rot caused by water accumulation, and providing a suitable microenvironment for the germination of Paris polyphylla seeds and the growth of seedlings. (3) The setting of the limiting movers realizes the synchronous transfer and centralized management of multiple seedling device bodies, simplifies the seedling operation process, improves the seedling efficiency, and at the same time, the precise cooperation of the bidirectional limiting protrusion and the limiting groove ensures the stability and safety of the seedling device body during the transfer and cultivation process.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] like Figure 1-7 As shown in this embodiment, a seedling raising device for planting Paris polyphylla includes an external placement box 1 for centralized seedling raising. The external placement box 1 contains several sets of seedling raising body 2. These seedling raising body 2 are connected and combined via limiting movers 3 for controlling the transfer of the seedling raising body 2. This achieves synchronous transfer and centralized management of multiple sets of seedling raising body 2, solving the problems of cumbersome and inefficient operation of individual seedling cups in traditional seedling raising processes. The external placement box 1 provides a relatively uniform environment for seedling raising. The separation support protrusion 4 separates the seedling raising body 2 from the inner bottom wall of the external placement box 1, preventing the bottom of the seedling raising body 2 from directly contacting water accumulation. This ensures smooth ventilation and drainage at the bottom of the seedling raising body 2, effectively reducing the risk of root rot of Paris polyphylla seeds or seedlings due to water accumulation. The seedling raising body 2 uses two symmetrically arranged seedling frames 20 to form a cup structure. This detachable design is one of the core innovations of this invention. When seedlings need to be removed, there is no need to tear or push them out like traditional hard plastic cups. Simply release the limiting mechanism between the bidirectional hook 23 and the limiting mover 3, and the two seedling frames 20 can be flipped open to both sides by rotating the connecting hinge 22, allowing the nutrient soil and seedlings to fall off naturally. This minimizes damage to the seedling roots and improves the survival rate of the seedlings. The drainage holes 21 on the side walls and bottom of the seedling frames 20 can drain excess water in time, preventing the nutrient soil from becoming too wet. This provides a suitable water environment for the germination of Paris polyphylla seeds and the growth of seedlings. The bidirectional hook 23 cooperates with the bidirectional limiting protrusion 31 on the limiting mover 3 to achieve stable limiting of the main body 2 of the seedling device during the transfer and cultivation process, ensuring the convenience and reliability of the operation. The setting of the through drainage hole 5 further ensures that no water will accumulate inside the external placement box 1, thus providing good drainage for the entire seedling system.

[0027] The limiting mover 3 includes two symmetrically arranged connecting support rods 30, with connecting moving columns 32 fixedly connected between the two ends of the two connecting support rods 30. The two connecting support rods 30 are arranged in parallel, providing a stable support structure for hanging the seedling container body 2, allowing multiple seedling container bodies 2 to be evenly and stably arranged among them. The connecting moving columns 32 are located at both ends of the connecting support rods 30, forming a "handle"-like structure, which makes it convenient for operators to lift the entire limiting mover 3 and the seedling container body 2 hanging on it with both hands or one hand. This realizes the overall and convenient transfer of the seedling container body 2, avoiding the scattering and inefficiency problems of traditional single seedling cup handling. The length of the connecting moving columns 32 is reasonably designed, ensuring both the operator's grip comfort and the force balance of the entire limiting mover 3 when lifted.

[0028] Several evenly distributed bidirectional limiting protrusions 31 are fixedly connected to the upper and lower sides of the outer wall of the connecting support rod 30. The size and shape of the bidirectional limiting protrusions 31 are consistent with the size and shape of the limiting grooves 24 of the bidirectional hook 23. The consistency of the size and shape of the bidirectional limiting protrusions 31 and the limiting grooves 24 of the bidirectional hook 23 is the key to achieving precise engagement between the two. When the seedling device body 2 is hooked onto the connecting support rod 30 via the bidirectional hook 23, the bidirectional limiting protrusions 31 on the connecting support rod 30 can perfectly engage with the limiting grooves 24 on the inner top wall of the bidirectional hook 23. When the connecting support rod 30 is lowered, the lower bidirectional limiting protrusions 31 engage with the lower limiting grooves 24 of the bidirectional hook 23. This design not only fixes the seedling device body 2 vertically to prevent it from sliding up and down, but also restricts the left and right displacement of the seedling device body 2 horizontally, ensuring that multiple seedling device bodies 2 are neatly arranged on the limiting mover 3. In terms of safety and stability, this sturdy locking structure effectively prevents the main body 2 of the seedling device from falling off the limiting mover 3 due to shaking when transferring the main body 2 of the seedling device, ensuring the safety of the transfer process. During the cultivation stage, the bidirectional limiting protrusion 31 below engages with the limiting groove 24 below, which can prevent the seedling frame 20 from accidentally flipping open, providing a stable cultivation space for the growth of Paris polyphylla seeds and seedlings. Several evenly distributed bidirectional limiting protrusions 31 allow multiple seedling device bodies 2 to be hung on one limiting mover 3, realizing batch operation and further improving seedling efficiency.

[0029] The main body 2 of the seedling incubator includes two symmetrically arranged seedling frames 20, which form a cup structure. Several evenly distributed drainage holes 21 are provided on the side walls and bottom of the two seedling frames 20 to drain excess water. The cup structure formed by the two seedling frames 20 provides an independent and suitable space for the cultivation of Paris polyphylla seeds. Each cup structure can be used for individual seed sowing and management, facilitating precise care for seedlings at different growth stages. The design of the drainage holes 21 on the side walls and bottom is particularly crucial; when overwatering or in high ambient humidity, excess water can be quickly drained. The drainage through these perforations prevents the nutrient soil from being oversaturated for extended periods. The optimized pore size of these perforations 21 ensures effective drainage while preventing soil particles from being lost with water, thus maintaining the stability of the soil structure. This preserves the necessary moisture and air ratio for seed germination and root growth. Additionally, the perforations 21 at the bottom can help prevent seedling roots from rotting due to prolonged immersion in water, while the perforations 21 on the side walls promote air circulation within the container, reducing the risk of mold growth and creating a dry and breathable microenvironment for the Paris polyphylla seedlings.

[0030] The two seedling frames 20 are configured with a bottom flip-up design. The bottoms of the two seedling frames 20 are rotatably connected by a rotating hinge 22. The sides of the bottoms of the two seedling frames 20 that are close to each other are rounded. The rotating hinge 22 provides a stable rotation axis for the flipping of the two seedling frames 20, making the opening and closing of the seedling frames 20 smoother and less strenuous. The bottom flip-up design ensures that when the main body 2 of the seedling device is opened, the two seedling frames 20 can be smoothly unfolded to both sides with the bottom as the fulcrum, avoiding the problem of uneven force causing the nutrient soil and seedlings to tip over in the traditional seedling taking method. The rounded corners of the bottoms of the two seedling frames 20 prevent movement interference at the bottom corners when the seedling frames 20 are unfolded.

[0031] Two seedling frames 20 are fixedly connected to C-shaped bidirectional hooks 23 on opposite sides of their upper surfaces, with the hooks 23 facing the same direction. The top and bottom walls of the bidirectional hooks 23 are provided with positioning grooves 24. The C-shaped design of the bidirectional hooks 23 allows them to stably hook onto the connecting support rod 30, providing a structural basis for the connection between the seedling unit 2 and the limiting mover 3. Their consistent orientation ensures that when multiple seedling units 2 are attached, they can be neatly arranged, facilitating subsequent centralized transfer and management. The positioning grooves 24 on the top and bottom walls of the bidirectional hooks 23 and the bidirectional hooks 24 on the connecting support rod 30... The precise fit of the limiting protrusions 31, this concave-convex interlocking structure, when the seedling device body 2 is attached to the limiting mover 3, whether during the lifting and transfer process, the upper limiting groove 24 fits with the bidirectional limiting protrusions 31, or when placed in the external placement box 1 for cultivation, the lower limiting groove 24 fits with the bidirectional limiting protrusions 31, can effectively limit the longitudinal and lateral movement of the seedling device body 2, preventing the seedling device body 2 from shaking, falling off, or the seedling frame 20 from accidentally unfolding during movement or cultivation, ensuring the stability and safety of the seedling process, and also providing a convenient operation method for the quick picking, placing and positioning of the seedling device body 2.

[0032] Several evenly distributed separation support protrusions 4 are fixedly connected to the bottom wall of the outer placement box 1. Several seedling device bodies 2 are placed on the surface of the corresponding separation support protrusions 4. The separation support protrusions 4 serve to support the seedling device bodies 2. At the same time, the separation support protrusions 4 raise the seedling device bodies 2 by a certain distance, so that an air circulation gap is formed between the bottom of the seedling device bodies 2 and the bottom wall of the outer placement box 1. This helps air to flow at the bottom of the seedling device bodies 2, promotes the rapid evaporation of water discharged from the drainage holes 21 at the bottom of the seedling frame 20, further reduces the humidity at the bottom of the seedling device bodies 2, provides a more sufficient oxygen environment for the respiration of the Paris polyphylla roots, and reduces the probability of root diseases.

[0033] Several evenly distributed through-drainage holes 5 are provided on the outer wall of the external placement box 1 near the lower part. The highest surface of the through-drainage holes 5 is lower than the highest surface of the separation support protrusion 4. The through-drainage holes 5 can promptly drain the water that seeps out of the seedling device body 2 or accumulates due to environmental factors inside the external placement box 1, avoiding water accumulation inside the box. The design that the highest surface of the through-drainage holes 5 is lower than the highest surface of the separation support protrusion 4 ensures that even if there is a small amount of water inside the external placement box 1, it will not submerge the bottom of the seedling device body 2 on the separation support protrusion 4. This ensures that the seedling device body 2 is always in a relatively dry environment, preventing water from seeping back into the bottom of the seedling device body 2 and affecting the drainage effect, further reducing the possibility of root rot in Paris polyphylla seedlings.

[0034] A method for cultivating and using a seedling raising device for planting Paris polyphylla includes the following specific operating steps: Step 1. Bring the two symmetrical seedling frames 20 together, keeping the seedling frames 20 together with one hand, and fill the seedling frames 20 with nutrient soil. Step 2. Hang the two-way hook 23 of the seedling frame 20 filled with nutrient soil on the outside of the connecting support rod 30 of the limiting mover 3, and push the two-way limiting protrusion 31 above the connecting support rod 30 into the upper limiting groove 24 of the corresponding two-way hook 23. Step 3. When the corresponding limiting mover 3 is filled with the seedling device body 2, lift the corresponding connecting moving column 32, move the corresponding limiting mover 3 and the corresponding seedling device body 2 into the external placement box 1, place the seedling device body 2 on the surface of the separation support protrusion 4, and lower the limiting mover 3 so that the bidirectional limiting protrusion 31 below the limiting mover 3 is inserted into the lower limiting groove 24 of the corresponding bidirectional hook 23. Step 4. Place Paris polyphylla seeds into the nutrient soil inside the corresponding seedling container body 2 for cultivation and planting. Excess water flows out from the drainage hole 21 of the seedling frame 20 and is discharged through the drainage hole 5 of the external box 1. Step 5. After the seedling raising is completed, lift the corresponding connecting moving column 32 with both hands so that the bidirectional limiting protrusion 31 above the connecting support rod 30 is inserted into the limiting groove 24 above the corresponding bidirectional hook 23, and lift the seedling device body 2 out to place it in the box 1. Step 6. Remove the limiting mover 3 from the corresponding positions of the seedling body 2, so that the corresponding bidirectional hook 23 loses its limiting position, and flip the seedling frame 20 to both sides to separate the seedling frame 20 from the nutrient soil, so that the Paris polyphylla seedlings can be separated from the nutrient soil as a whole.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.

The cultivation and use method of the seedling raising device for planting Paris polyphylla according to any one of claims 1-7, characterized in that, The specific operating steps are as follows: Step 1. Bring the two symmetrical seedling frames (20) together, hold the seedling frames (20) together with one hand, and fill the seedling frames (20) with nutrient soil. Step 2. Hang the two-way hook (23) of the seedling frame (20) filled with nutrient soil on the outside of the connecting support rod (30) of the limiting mover (3), and push the two-way limiting protrusion (31) above the connecting support rod (30) into the upper limiting groove (24) of the corresponding two-way hook (23); Step 3. When the corresponding limiting mover (3) is filled with the seedling body (2), lift the corresponding connecting moving column (32), move the corresponding limiting mover (3) and the corresponding seedling body (2) into the external placement box (1), place the seedling body (2) on the surface of the separation support protrusion (4), and put down the limiting mover (3) so that the bidirectional limiting protrusion (31) below the limiting mover (3) is inserted into the lower limiting groove (24) of the corresponding bidirectional hook (23); Step 4. Place Paris polyphylla seeds into the nutrient soil inside the corresponding seedling container body (2) for cultivation and planting. Excess water flows out from the drainage through hole (21) of the seedling frame (20) and is discharged through the drainage hole (5) of the external placement box (1). Step 5. After the seedling raising is completed, lift the corresponding connecting moving column (32) with both hands so that the bidirectional limiting protrusion (31) above the connecting support rod (30) is inserted into the limiting groove (24) above the corresponding bidirectional hook (23), and lift the seedling device body (2) out to place the box (1). Step 6. Remove the limiting mover (3) from the corresponding seedling body (2) position, so that the corresponding bidirectional hook (23) loses its limit, and flip the seedling frame (20) to both sides, so that the seedling frame (20) is separated from the nutrient soil, and the Paris polyphylla seedlings are separated from the nutrient soil as a whole.
