Description

Technical Field

[0001] This invention relates to the field of loofah seed seedling cultivation technology, specifically to loofah seed seedling cultivation device and its usage method. Background Technology

[0002] As a common vegetable, seedling cultivation is a crucial step in the planting process of loofah. In order to improve the germination rate and growth quality of loofah seeds, the design and development of seedling cultivation devices are particularly important.

[0003] When cultivating loofah seeds, fill the seedling tray with the prepared seedling soil, gently compact it, and then put 1 to 2 treated seeds in each hole. After germination, the seedlings and nutrient soil need to be pulled out and transplanted into the soil together. This mainly helps to protect the root system, maintain a stable growth environment, and improve the survival rate. Because the potting soil needs to be watered frequently to keep it moist, it tends to stick to the seedling tray, making it difficult to remove the soil and seedlings from the seedling cups. Furthermore, since the soil is buried inside the seedling cups, the seedlings are the main part protruding from the outside. You cannot simply grab the seedlings and pull them out, as this would cause the root system to be subjected to strong pulling, resulting in the breakage of a large number of roots. After the seedling cup is filled with nutrient soil, the space left for operation is very limited. It is difficult for people to put their fingers or tools into the seedling cup to directly grasp the nutrient soil and take it out. There are currently two methods. One is to use a small shovel, small fork or other suitable auxiliary tools to insert into the seedling cup and then pry out the nutrient soil. However, this method will cause the seedling roots to be scratched or broken after the tool comes into contact with the stem of the seedling, which will affect the seedling's ability to absorb water and fertilizer, resulting in a longer recovery time or death. Another method is to press down on the seedling tray directly. Since the seedling tray is usually made of plastic, the bottom of the seedling cup is in direct contact with the ground. When you press down on the seedling tray, the seedling cup will deform under the force, the internal space will be compressed, and then the nutrient soil inside the seedling cup will be exposed. The drawbacks of this method are also obvious. The shrinking walls of the seedling cups will create wrinkles, similar to the wave shape of a corrugated pipe. The inward shrinking cup walls will directly squeeze the seedling roots (especially the taproot), causing mechanical damage or breakage, which will affect water absorption and growth recovery after transplanting. Although there are drainage holes at the bottom of the seedling cups, and you can reach into the drainage holes to push the soil out, the drainage holes are usually small and it is difficult to operate them with your fingers or tools. This is especially inefficient for densely packed seedling cups. Moreover, improper operation can easily break up the nutrient soil, which can easily lead to loose soil clumps and broken roots (especially the taproot), affecting the water absorption capacity after transplanting. Summary of the Invention

[0004] The purpose of this invention is to provide a loofah seedling raising device to solve the problems mentioned in the background art.

[0005] Another object of the present invention is to provide a method of use.

[0006] To solve the above-mentioned technical problems, the present invention provides a loofah seedling raising device and method of use, comprising a seedling tray body, wherein the seedling tray body has multiple seedling holes evenly spaced apart, and seedling cups are arranged in the seedling holes, the seedling cups comprising, The top edge of the seedling cup is connected to the seedling hole and extends downward to form a cup wall that runs through the top and bottom. The seedling cup holder is movably inserted into the seedling cup cover, and any two opposite sides of the seedling cup holder are provided with strip openings facing each other; The support belt is located inside the seedling cup holder. Its two ends pass through two strip openings and are connected to the inner wall of the seedling cup cover. It is used to lift the support belt upward when the seedling cup cover moves downward relative to the seedling cup holder.

[0007] Furthermore, the inner bottom wall of the seedling cup holder is provided with a first bottom surface and a second bottom surface, and the boundary between the two has a height difference, forming a stepped surface; The supporting belt has a through-hole strip-shaped drain. The strip-shaped drain extends along the boundary line between the first bottom surface and the second bottom surface. The center line of the extension direction of the strip-shaped drain is in the same longitudinal plane as the boundary line between the two bottom surfaces.

[0008] Furthermore, it also includes a drain outlet, which is located on the step surface of the dividing line between the first bottom surface and the second bottom surface, and the drain outlet is connected to the outside.

[0009] Furthermore, the bottom of the seedling cup holder is provided with a strip-shaped groove, which is located directly below the dividing line between the first bottom surface and the second bottom surface. The bottom of the strip-shaped groove is connected to the outside, and the top of the strip-shaped groove is connected to the drain outlet. A counterweight is provided inside the strip groove. The bottom of the counterweight is parallel to the bottom of the seedling cup holder, and the top of the counterweight abuts against the inner top wall of the strip groove. Two connecting blocks connect the top of the counterweight to the inner top wall of the drain outlet.

[0010] Furthermore, the bottom of the seedling cup holder is elastic, and the shape of the counterweight bar is adapted to the strip-shaped through groove.

[0011] Furthermore, the contact surface between the seedling cup holder and the seedling cup cover is provided with a first inclined surface, and the contact surface between the seedling cup cover and the first inclined surface is provided with a second inclined surface. The outer wall of the first inclined surface abuts against the outer wall of the second inclined surface, and the lower inclined ends of the second inclined surface and the first inclined surface correspond to the outside of the seedling cup holder.

[0012] Furthermore, it also includes a groove, which is circumferentially arranged on the outer wall of the seedling cup holder and communicates with the first inclined surface. The protrusion is circumferentially connected to the inner wall of the seedling cup cover. The bottom of the protrusion is connected to the top of the second inclined surface, and the top of the protrusion abuts against the inner top wall of the groove. The strip opening communicates with the groove and corresponds to a portion of the protrusion. The two ends of the support belt pass through the two strip openings and connect to the outer wall of the protrusion.

[0013] Furthermore, the inner wall of the seedling tray body is connected with multiple ribs, which are distributed between multiple seedling holes.

[0014] A method of use, applied to any of the above-described loofah seedling raising devices; Step 1, Assembly: Insert the seedling cup holder into the seedling cup cover, then place the support strip inside the seedling cup holder, and attach the two ends of the support strip to the seedling cup cover through the two slots respectively. Step 2, Sowing: Fill the prepared nutrient soil into the seedling cup; Step 3, Separation: After germination, press down on the main body of the seedling tray and the seedling cup cover. As the seedling cup cover moves downwards, pull the support strap upwards, and then lift the soil out through the support strap, thus separating the nutrient soil from the seedling cup.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, when the seedling cup cover is pressed down, the two ends of the support belt will move down together, causing the hanging part of the support belt inside the seedling cup to gather upward and lift the soil block smoothly, reducing the pressure of the soil being wrapped by the seedling cup. During this process, the support belt remains straight and wrinkle-free, avoiding squeezing the soil block, making it easier for the roots and the protective soil to completely detach from the cup base, reducing the risk of transplanting damage. The soil block is lifted by external force, which protects the roots and simplifies the soil removal operation.

[0016] 2. In this invention, when the support belt hangs down naturally, the two sides of the strip-shaped drainage outlet are misaligned due to the difference in bottom height, and the opening is unobstructed, which facilitates the drainage of excess water in the soil; after the support belt is pulled down, the strip-shaped drainage outlet returns to the closed state under the action of tension, which retains a small gap for ventilation and effectively prevents soil loss.

[0019] 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.

[0020] This invention provides a technical solution: See Figures 1-11 As shown, the loofah seedling raising device includes a seedling tray body 1, with multiple seedling holes evenly spaced on the seedling tray body 1. Seedling cups are placed inside the seedling holes, and each seedling cup includes... The top edge of the seedling cup cover 3 is fixedly connected to the seedling hole and extends downward to form a cup cover wall that runs through the top and bottom. The seedling cup holder 4 is movably inserted into the seedling cup cover 3, and any two opposite sides of the seedling cup holder 4 are provided with strip-shaped openings 5 ​​with opposite openings; The support belt 6 is set inside the seedling cup base 4. The two ends of the support belt 6 pass through two strip openings 5 ​​and are fixedly connected to the inner wall of the seedling cup cover 3. The support belt 6 and the seedling cup cover 3 can be glued together with strong glue so that they will not easily fall off or separate. The support belt 6 is used to lift the seedling cup cover 3 upward when it moves down relative to the seedling cup base 4. There is a gap between the top of the seedling cup holder 4 and the top of the seedling cup cover 3. A drain outlet 403 is provided at the bottom of the seedling cup holder 4. The drain outlet 403 is located at the center of the bottom of the seedling cup holder 4. Two strip-shaped openings 5 ​​are provided on the seedling cup holder 4. The inner wall of the seedling cup cover 3 is in close contact with the outer wall of the seedling cup holder 4.

[0021] The potting soil falls through the seedling holes into the seedling cup cover 3 and the seedling cup base 4. The seedling cup cover 3 is located above the seedling cup base 4. The internal structure of the seedling cup cover 3 and the seedling cup base 4 is visible after they are connected. Figure 7 When the loofah seeds germinate, and the seedlings have grown 2-3 true leaves, the seedlings and nutrient soil can be dug out of the seedling cups and transplanted into the soil. First, the user can press down on both sides of the seedling tray body 1 with both hands, and the bottom of the seedling cup base 4 will contact the ground. When pressing the seedling tray body 1, the seedling tray body 1 will move the seedling cup cover 3 downward. Both the seedling cup cover 3 and the seedling cup base 4 are made of hard plastic and will not be easily deformed. Since the seedling cup cover 3 is slightly larger than the seedling cup holder 4, when connecting the seedling cup cover 3 and the seedling cup holder 4, first place the seedling cup holder 4 into the seedling cup cover 3 from above. Figure 3 As can be seen, the tops of both the seedling cup cover 3 and the seedling cup base 4 are wider than their bottoms. Then, the seedling cup base 4 falls inside the seedling cup cover 3. When the wider top of the seedling cup base 4 gradually approaches the smaller bottom of the seedling cup cover 3, the top of the seedling cup base 4 will be stuck inside the seedling cup cover 3, making it impossible for the top of the seedling cup base 4 to be pulled out from the bottom of the seedling cup cover 3. At this time, the seedling cup cover 3 and the seedling cup base 4 form an interlocking state, and the inner wall of the seedling cup cover 3 is in close contact with the outer wall of the seedling cup base 4. The top of the nutrient soil is parallel to the top of the seedling tray body 1. Press the seedling tray body 1, and after the seedling tray body 1 moves the seedling cup cover 3 downward, part of the nutrient soil will be exposed and protrude from the top of the seedling hole. The exposed nutrient soil occupies about 1 / 3 of its height. The seedling cup cover 3 releases the pressure of wrapping the part of the nutrient soil. The area originally covered by the seedling cup cover 3 is exposed and forms a grasping point. exist Figure 4 As can be seen, the two strip-shaped openings 5 ​​are respectively opened on the two sides of the seedling cup holder 4, and the two strip-shaped openings 5 ​​are horizontally aligned. Figure 5 and Figure 6From this perspective, it can be seen that the support belt 6 is set inside the seedling cup holder 4. The support belt 6 itself is relatively soft, so it naturally hangs down inside the seedling cup holder 4 due to gravity. The two ends of the support belt 6 are inserted into the strip-shaped openings 5 ​​on both sides, and then... Figure 11 From the perspective of the protrusion 14, one side corresponds to the slot 5, so the end of the support belt 6 inserted into the slot 5 is fixedly connected to the protrusion 14 and the corresponding side of the slot 5. When the seedling cup cover 3 moves down, it pulls both ends of the support belt 6 down as well. The two ends of the support belt 6 move downwards and outwards from the seedling cup base 4 along with the seedling cup cover 3. At the same time, the area of ​​the support belt 6 inside the seedling cup base 4 is also continuously pulled outwards through the strip opening 5. Then, the area of ​​the support belt 6 hanging down inside the seedling cup base 4 gradually moves upwards. Since part of the support belt 6 is laid on the inner bottom wall of the seedling cup base 4 when it hangs down, the nutrient soil is on the support belt 6. When the support belt 6 gradually moves upwards, it will push the nutrient soil upwards, causing a part of the nutrient soil inside the seedling cup base 4 to move upwards. The soil is partially moved upwards out of the seedling cup base 4, reducing the contact area with the seedling cup base 4. The resistance of the soil being wrapped by the seedling cup base 4 is also smaller. The support strip 6 is taut when it is pulled out, so it is less likely to wrinkle and squeeze the soil. This makes it easier for the roots to detach from the seedling cup base 4 as a whole when the soil is removed, further preserving the "root protection soil" around the roots and reducing root damage during transplanting. The seedling cup is designed to be wider at the top and narrower at the bottom, with rounded edges. The top of the seedling cup cover 3 is parallel to the top of the seedling tray body 1 and the top of the seedling hole. The overall shape of the seedling cup cover 3 and the seedling cup base 4 is a frustum-shaped structure that is wider at the top and narrower at the bottom. Firstly, this shape can guide the roots to grow naturally downwards and reduce entanglement. Secondly, the cup wall of the frustum-shaped structure is inclined. When the nutrient soil is filled, the contact area with the cup wall decreases as the height increases, making it narrower at the bottom and wider at the top. When demolding, the frictional resistance between the soil and the cup wall is mainly concentrated in the narrower area at the bottom, while the frictional force in the wider area at the top is significantly reduced, and the overall demolding requires less external force. Moreover, the inclined cup wall forms a "draft angle" similar to the demolding of a mold, and the soil will naturally slide out along the inclined surface under the action of gravity or external force, avoiding the "vacuum adsorption" or "jamming" phenomenon caused by the vertical cup wall. Secondly, the rounded corners of the seedling cup cover 3 and the seedling cup base 4 eliminate stress concentration points on the right-angled cup wall, reduce soil particles getting stuck at the corners, and make the pressure distribution between the soil and the cup wall more even, which can reduce the risk of local adhesion. Moreover, the rounded corners can also prevent sharp corners from scratching the roots and reduce mechanical damage during transplanting.

[0022] See Figures 1-9The inner bottom wall of the seedling cup holder 4 is provided with a first bottom surface 401 and a second bottom surface 402, and there is a height difference between the two, forming a stepped surface; The support belt 6 has a through-hole 9. The through-hole 9 extends along the boundary line between the first bottom surface 401 and the second bottom surface 402. The center line of the extension direction of the through-hole 9 and the boundary line between the two bottom surfaces are in the same longitudinal plane.

[0023] The strip-shaped drain outlet 9 is elongated and has a long, narrow shape. Figure 6 From the perspective of the strip-shaped drain outlet 9, the center is directly opposite the boundary line between the first bottom surface 401 and the second bottom surface 402. Figure 6 From the perspective of the support belt 6, when it hangs naturally in the seedling cup holder 4, part of the area of ​​the support belt 6 is laid on the inner bottom wall of the seedling cup holder 4, while the left side of the strip-shaped drain outlet 9 is on the second bottom surface 402, and the right side of the strip-shaped drain outlet 9 is on the first bottom surface 401. When the support strip 6 is covered with nutrient soil, the weight of the nutrient soil will exert pressure on the support strip 6. At this time, the left side of the strip-shaped drainage outlet 9 will be close to the top of the second bottom surface 402, while the right side of the strip-shaped drainage outlet 9 will be close to the top of the first bottom surface 401. Since the height of the first bottom surface 401 and the second bottom surface 402 is different, the height of the left and right sides of the strip-shaped drainage outlet 9 is also different. At this time, the left and right sides of the strip-shaped drainage outlet 9 will be staggered. Since the left and right sides of the strip-shaped drainage outlet 9 are staggered, the strip-shaped drainage outlet 9 is in the open state, and then the excess water in the soil can flow out directly through the strip-shaped drainage outlet 9. Then, when the two ends of the support belt 6 are pulled downward, the support belt 6 is stretched, causing the area near the support belt 6 and the strip drain outlet 9 to move upward. At this time, the pressure of the soil on both sides of the strip drain outlet 9 is relatively uniform, and there is no limitation from the first bottom surface 401 and the second bottom surface 402. Therefore, the suspended strip drain outlet 9 no longer intersects, and the left and right sides of the strip drain outlet 9 are at the same level. At this time, the strip drain outlet 9 is in a closed state. Although there will still be gaps in the closed strip drain outlet 9, the gaps in the closed strip drain outlet 9 are very fine, and the soil will not easily fall from the strip drain outlet 9 at this time. This prevents some soil from falling out through the strip-shaped drainage outlet 9 when the soil is pushed out.

[0024] See Figures 4-10 It also includes a drain outlet 403, which is located on the step surface of the dividing line between the first bottom surface 401 and the second bottom surface 402, and the drain outlet 403 is connected to the outside.

[0025] Firstly, the drainage outlet 403 located at the bottom of the seedling cup base 4 plays a very important role. During the seedling process, proper watering is crucial for seedling growth. Without the drainage outlet 403, excessive watering will cause water to accumulate in the cup, leading to overly wet soil and affecting soil aeration. The drainage outlet 403 allows excess water to drain out in time, preventing water accumulation that can cause root rot and lack of oxygen, and creating a suitable humidity environment for the seedling roots. Since the nutrient soil is on the support strip 6, the strip-shaped drainage outlet 9 opened on the support strip 6 corresponds to the drainage outlet 403. This allows excess water to flow through the strip-shaped drainage outlet 9 to the location of the drainage outlet 403, and then flow from the drainage outlet 403 to the outside. The center of the strip-shaped drainage outlet 9 is directly opposite the dividing line between the first bottom surface 401 and the second bottom surface 402. by Figure 9 From the perspective of the drain outlet 403, one side of the drain outlet 403 corresponds to the second bottom surface 402, and the drain outlet 403 is located on the side wall where the first bottom surface 401 and the second bottom surface 402 are in contact. At this time, the strip drain outlet 9 in the open state corresponds to the drain outlet 403, and then the excess water in the soil can flow directly to the drain outlet 403 through the strip drain outlet 9.

[0026] See Figures 3-10 The bottom of the seedling cup holder 4 is provided with a strip groove 11. The strip groove 11 is located directly below the dividing line between the first bottom surface 401 and the second bottom surface 402. The bottom of the strip groove 11 is connected to the outside, and the top of the strip groove 11 is connected to the drain outlet 403. A counterweight 12 is provided inside the strip groove 11. The bottom of the counterweight 12 is parallel to the bottom of the seedling cup holder 4, and the top of the counterweight 12 abuts against the inner top wall of the strip groove 11. Two connecting blocks 13 are fixedly connected between the top of the counterweight 12 and the inner top wall of the drain outlet 403.

[0027] After the soil is placed into the seedling cup, the position of the main body 1 of the seedling tray needs to be moved. After the main body 1 of the seedling tray is lifted, some soil will fall out from the drain 403 because the bottom of the seedling cup holder 4 is suspended. When the seedling cup holder 4 touches the ground, the bottom of the counterweight 12 will also touch the ground. At this time, the counterweight 12 is located inside the strip groove 11. When the outer wall of the counterweight 12 is in contact with the inner wall of the strip groove 11, the bottom of the counterweight 12 is the same as the bottom of the seedling cup holder 4 and is also in contact with the ground. When the seedling tray body 1 is lifted, the bottom of the seedling cup holder 4 is in a suspended state. Since the weight of the counterweight 12 is greater than that of the seedling cup holder 4 but will not exceed the weight of the entire seedling tray body 1, the counterweight 12 will fall down after the bottom of the seedling cup holder 4 is suspended. The falling counterweight 12 will pull the inner top wall of the drain outlet 403 toward the top surface of the second bottom surface 402 through the connecting block 13. After the top surface of the drain outlet 403 is close to the edge of the top surface of the second bottom surface 402, the inlet on the side of the drain outlet 403 is closed. This prevents some soil from falling out of the drain outlet 403 when the main body of the seedling tray 1 is lifted and the bottom of the seedling cup holder 4 is suspended. It is worth noting that the weight of the counterweight 12 is only enough to pull the inner top wall of the drain outlet 403 close to the edge of the second bottom surface 402, without deforming the entire seedling cup holder 4. Therefore, the specific weight of the counterweight 12 can be determined according to the material strength of the seedling cup holder 4.

[0028] See Figures 6-10 The bottom of the seedling cup holder 4 is elastic, and the shape of the counterweight strip 12 is adapted to the strip groove 11.

[0029] The bottom of the seedling cup holder 4 has a certain degree of elasticity so that the inner top wall of the drain outlet 403 can deform downwards. The counterweight 12 is adapted to the strip groove 11. So when the bottom of the seedling cup holder 4 contacts the ground, the counterweight 12 will also contact the ground. Then the counterweight 12 will be inserted into the strip groove 11, so that the bottom of the counterweight 12 is parallel to the bottom of the seedling cup holder 4, thus ensuring the overall flatness.

[0030] See Figures 3-8 The contact surface between the seedling cup holder 4 and the seedling cup cover 3 is provided with a first inclined surface 7, and the contact surface between the seedling cup cover 3 and the first inclined surface 7 is provided with a second inclined surface 10. The outer wall of the first inclined surface 7 abuts against the outer wall of the second inclined surface 10, and the lower inclined ends of the second inclined surface 10 and the first inclined surface 7 are both aligned with the outside of the seedling cup holder 4.

[0031] by Figure 7 From the perspective of the seedling cup cover 3 and the seedling cup base 4, the contact surface is opened as the second inclined surface 10, and the contact surface between the seedling cup base 4 and the second inclined surface 10 is opened as the first inclined surface 7. The surfaces of the second inclined surface 10 and the first inclined surface 7 are in close contact. The lower inclined ends of the first inclined surface 7 and the second inclined surface 10 are both facing the outer periphery of the seedling cup base 4. In this way, when the seedling cup cover 3 is squeezed by the seedling tray body 1, it will slide down along the outer wall of the first inclined surface 7 through the second inclined surface 10. The downward movement trajectory of the seedling cup cover 3 is towards the outside of the seedling cup base 4, which will not exert pressure on the nutrient soil, avoid the cup wall wrinkles squeezing the main root, and also avoid problems such as root damage and soil clod breakage in traditional methods. At the same time, it significantly improves transplanting efficiency and success rate. In addition, pressing the main body 1 of the seedling tray can release the nutrient soil in multiple seedling cups at one time. Batch operation reduces the processing time of a single plant and can quickly complete the transplanting of the whole tray of seedlings.

[0032] See Figures 4-11It also includes a groove 8, which is circumferentially arranged on the outer wall of the seedling cup holder 4, and the groove 8 is connected to the first inclined surface 7. The protrusion 14 is circumferentially connected to the inner wall of the seedling cup cover 3. The bottom of the protrusion 14 is fixedly connected to the top of the second inclined surface 10, and the top of the protrusion 14 abuts against the inner top wall of the groove 8. The slot 5 is connected to the groove 8, and the slot 5 corresponds to a part of the protrusion 14. The two ends of the support belt 6 pass through the two slots 5 respectively and are fixedly connected to the outer wall of the protrusion 14.

[0033] The groove 8 is formed on the outer wall of the seedling cup holder 4 and is located at the top of the first inclined surface 7. Figure 4 As can be seen, the groove 8 is recessed into the seedling cup holder 4, and the protrusion 14 is fixed to the inner wall of the seedling cup cover 3. Figure 11 As can be seen, the protrusion 14 protrudes from the inner wall of the seedling cup cover 3. When the first inclined surface 7 and the second inclined surface 10 abut against each other, the protrusion 14 is stuck in the groove 8. The top of the protrusion 14 is flat, and the inner top wall of the groove 8 is also flat. Therefore, the top surface of the protrusion 14 abuts against the inner top wall of the groove 8. In this way, when the seedling tray body 1 is lifted, the seedling cup cover 3 can hook the groove 8 through the protrusion 14, thereby lifting the seedling cup base 4 together. Although the top of the seedling cup holder 4 can be locked inside the seedling cup cover 3, the seedling cup cover 3 has a certain degree of elasticity. After the seedling cup holder 4 is filled with nutrient soil, the weight of the seedling cup holder 4 will increase. Therefore, when the seedling tray body 1 is lifted, the weighted seedling cup holder 4 may slide off the bottom of the seedling cup cover 3. The engagement between the protrusion 14 and the groove 8 can prevent the seedling cup holder 4 from falling out of the seedling cup cover 3.

[0034] See Figure 2 The inner wall of the seedling tray body 1 is fixedly connected with multiple ribs 2, which are distributed between multiple seedling holes.

[0035] The seedling tray body 1 is quite heavy when filled with nutrient soil. The ribs 2 can increase the rigidity of the tray body and reduce bending or denting caused by its own weight or external forces such as handling or stacking. When the seedling tray body 1 is pressed down to allow the seedling cup cover 3 to move down along the seedling cup base 4, if the seedling tray body 1 is deformed or bent, some of the seedling cup covers 3 will not be pressed down and moved. The ribs 2 increase the strength of the seedling tray body 1, so that when the seedling tray body 1 is lifted or pressed down, it can remain relatively flat as a whole, ensuring that the seedling cup covers 3 move down synchronously and evenly along the seedling cup base 4, and preventing some seedling cup covers 3 from not being pressed down due to the deformation of the seedling tray body 1. Secondly, the ribs 2 are distributed among multiple seedling holes to form a support network, which distributes the pressure throughout the tray and avoids stress concentration.

[0036] See Figures 1-11 The present invention also provides a method of use for the loofah seedling raising device applied to any of the above embodiments, wherein the seedling tray body 1 further includes, Step 1, Assembly: Insert the seedling cup holder 4 into the seedling cup cover 3, then place the support belt 6 into the seedling cup holder 4, and pass both ends of the support belt 6 through the two strip openings 5 ​​and attach them to the seedling cup cover 3. Step 2, sowing: Fill the prepared nutrient soil into the seedling cup, gently compact it, and spray the seedling cup evenly with water using a spray bottle or sprayer to make the substrate fully moist but without water accumulation. Use different sowing methods according to the size and characteristics of the seeds. After sowing, gently cover with a thin layer of substrate, the thickness of which should just cover the seeds. Step 3, Separation: After germination, press down on the main body 1 of the seedling tray and the seedling cup cover 3. As the seedling cup cover 3 moves downward, it pulls the support belt 6 upward, thereby lifting the soil out through the support belt 6, thus separating the nutrient soil from the seedling cup.
