Description

Technical Field

[0001] The present invention relates to the technical field of towel gourd seedling raising, and specifically to a towel gourd seedling raising device and its usage method. Background Art

[0002] As a common vegetable, towel gourd, seedling raising is a key link in its planting process. In order to improve the germination rate and growth quality of towel gourd seeds, the design and research and development of seedling raising devices are particularly important.

[0003] When raising seedlings from towel gourd seeds, the prepared seedling raising soil is filled into the seedling raising tray and gently compacted. Then, 1 to 2 processed seeds are placed in each hole. After germination, the seedlings and the nutrient soil need to be pulled out and transplanted into the land together. This mainly serves to protect the root system, maintain the stability of the growth environment, and improve the survival rate; Since the nutrient soil needs to be watered frequently to keep it moist, the nutrient soil is prone to sticking to the seedling raising tray, making it difficult to take out the nutrient soil and the seedlings from the seedling raising cup; furthermore, since the soil is buried in the seedling raising cup and mainly the seedlings protrude outside the seedling raising cup, the seedlings cannot be directly grasped to pull out the two together, which will cause strong pulling on the root system and result in a large number of root hairs breaking; After the nutrient soil fills the seedling raising cup, the space left for operation is very limited. It is very difficult for people to insert their fingers or tools into the interior of the seedling raising cup to directly hold the nutrient soil and take it out. There are currently two methods. One is to use appropriate auxiliary tools such as small shovels and small forks to insert into the seedling raising cup and then pry out the nutrient soil. However, after the tool contacts the stem of the seedling, it will cause abrasions or breaks to the roots of the seedling, thereby affecting the water and fertilizer absorption ability of the seedling and resulting in an extended slow seedling time or death; Another method is to directly press the seedling raising tray. Since the seedling raising tray is usually made of plastic and the bottom of the seedling raising cup is in direct contact with the ground, when pressing down on the seedling raising tray at this time, the seedling raising cup deforms under force and the internal space is compressed, and then the nutrient soil in the seedling raising cup will be exposed; The defect of this method is also obvious. The contracted wall of the seedling raising cup will produce wrinkles, similar to the wave shape of a corrugated pipe. The inwardly contracting cup wall will directly squeeze the root system of the seedling (especially the main root), resulting in mechanical damage or breakage, affecting water absorption and growth recovery after transplantation. Although there are drainage holes at the bottom of the seedling raising cup and the soil can be pushed out by inserting the hand into the drainage hole, the drainage holes are usually small, and it is difficult for fingers or tools to reach in for operation. Especially for densely arranged seedling raising cups, the efficiency is extremely low, and improper operation is likely to poke and scatter the nutrient soil, easily causing the soil mass to loosen and the root system (especially the main root) to break, affecting the water absorption ability after transplantation. Summary of the Invention

[0004] The purpose of the present invention is to provide a towel gourd seedling raising device to solve the problems raised in the above background art.

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

[0006] To solve the above technical problems, the loofah seedling raising device and the method of use provided by the present invention include a main body of a seedling raising tray. The main body of the seedling raising tray is equidistantly provided with a plurality of seedling raising holes. A seedling raising cup is arranged in the seedling raising hole. The seedling raising cup includes, A seedling raising cup cover, the top edge wall of which is connected to the seedling raising hole and extends downward to form a cup cover wall that penetrates up and down; A seedling raising cup seat, which is movably inserted into the seedling raising cup cover. Opposite sides of the seedling raising cup seat are provided with strip-shaped openings with opposite openings; A supporting belt, which is arranged inside the seedling raising cup seat. Both ends of the supporting belt respectively pass through the two strip-shaped openings and are connected to the inner wall of the seedling raising cup cover, and are used for lifting the supporting belt upward when the seedling raising cup cover moves downward relative to the seedling raising cup seat.

[0007] Furthermore, the inner bottom wall of the seedling raising cup seat is provided with a first bottom surface and a second bottom surface, and there is a height difference at the boundary between the two, forming a stepped surface; The supporting belt is provided with a strip-shaped drain opening, and the strip-shaped drain opening extends along the boundary line between the first bottom surface and the second bottom surface. The center line of the extending direction of the strip-shaped drain opening and the boundary line between the two bottom surfaces are in the same longitudinal plane.

[0008] Furthermore, it also includes a drain port, which is arranged on the stepped surface of the boundary line between the first bottom surface and the second bottom surface, and the drain port communicates with the outside.

[0009] Furthermore, the bottom of the seedling raising cup seat is provided with a strip-shaped through groove, the strip-shaped through groove is located directly below the boundary line between the first bottom surface and the second bottom surface, the bottom of the strip-shaped through groove communicates with the outside, and the top of the strip-shaped through groove communicates with the inside of the drain port; A weight bar is arranged in the strip-shaped through groove. The bottom of the weight bar is parallel to the bottom of the seedling raising cup seat, the top of the weight bar abuts against the inner top wall of the strip-shaped through groove, and two connecting blocks are connected between the top of the weight bar and the inner top wall of the drain port.

[0010] Furthermore, the bottom of the seedling raising cup seat has elasticity, and the outer shape of the weight bar is adapted to the strip-shaped through groove.

[0011] Furthermore, a first inclined surface is provided on the contact surface between the seedling raising cup seat and the seedling raising cup cover, a second inclined surface is provided on the contact surface between the seedling raising cup cover and the first 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 both correspond to the outside of the seedling raising cup seat.

[0012] Furthermore, it also includes a groove, which is circumferentially arranged around the outer wall of the seedling raising cup seat and communicates with the first inclined surface; The bump is circumferentially connected to the inner wall of the seedling-raising cup cover around the seedling-raising cup. The bottom of the bump is connected to the top of the second inclined surface, and the top of the bump abuts against the inner top wall of the groove. The strip-shaped opening is in communication with the inside of the groove, and the strip-shaped opening corresponds to a partial area of the bump. Both ends of the supporting belt respectively pass through the two strip-shaped openings and are connected to the outer wall of the bump.

[0013] Furthermore, a plurality of ribs are connected to the inner wall of the main body of the seedling-raising tray, and the ribs are distributed among a plurality of seedling-raising holes.

[0014] A usage method is applied to the loofah seedling-raising device described in any one of the above. Step 1, assembly: Insert the seedling-raising cup base into the seedling-raising cup cover. Then, place the supporting belt in the seedling-raising cup base, and respectively pass both ends of the supporting belt through the two strip-shaped openings and bond them to the seedling-raising cup cover. Step 2, sowing: Fill the prepared nutrient soil into the seedling-raising cup. Step 3, separation: After germination, press the main body of the seedling-raising tray and the seedling-raising cup cover. While the seedling-raising cup cover moves downward, pull the supporting belt upward to converge. Then, lift the soil out through the supporting belt to achieve the separation of the nutrient soil from the seedling-raising cup.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, when pressing the seedling-raising cup cover to move downward, it will drive both ends of the supporting belt to move downward together, making the hanging part of the supporting belt in the seedling-raising cup converge upward and smoothly lift the soil block, reducing the wrapping pressure of the soil by the seedling-raising cup. During this process, the supporting belt remains straight and without wrinkles, avoiding squeezing the soil block, making it easier for the root system to be completely separated from the cup base with the root-protecting soil, reducing the risk of transplanting damage, and realizing the lifting of the soil block through external force traction, which not only protects the root system but also simplifies the soil-taking operation.

[0016] 2. In the present invention, when the supporting belt hangs naturally, there is an up-and-down dislocation on both sides of the strip-shaped water drain opening due to the height difference of the bottom surface, and the opening is unobstructed, facilitating the drainage of excess water in the soil; after pulling down the supporting belt, the strip-shaped water drain opening returns to the closed state under the action of the tensile force, not only retaining a small gap for ventilation but also effectively preventing soil loss.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] The present invention provides a technical solution: Refer to Figures 1 - 11 As shown, the loofah seedling-raising device includes a main body 1 of the seedling-raising tray. A plurality of seedling-raising holes are equidistantly arranged in the main body 1 of the seedling-raising tray. A seedling-raising cup is arranged in the seedling-raising hole. The seedling-raising cup includes, a seedling-raising cup cover 3, the top edge wall of which is fixedly connected to the seedling-raising hole and extends downward to form a cup cover wall that penetrates up and down; a seedling-raising cup seat 4, which is movably inserted into the seedling-raising cup cover 3. Opposite strip-shaped openings 5 with opposite openings are arranged on any two opposite sides of the seedling-raising cup seat 4; The supporting belt 6 is arranged inside the seedling-raising cup base 4. Both ends of the supporting belt 6 respectively pass through two strip-shaped openings 5 and are fixedly connected to the inner wall of the seedling-raising cup cover 3. The supporting belt 6 and the seedling-raising cup cover 3 can be adhesively connected by using strong glue and will not easily fall off or separate, and are used for the supporting belt 6 to lift upward when the seedling-raising cup cover 3 moves downward relative to the seedling-raising cup base 4; There is a gap between the top of the seedling-raising cup base 4 and the top of the seedling-raising cup cover 3. A drain hole 403 is opened at the bottom of the seedling-raising cup base 4. The drain hole 403 is located at the central part of the bottom of the seedling-raising cup base 4. Two strip-shaped openings 5 are opened on the seedling-raising cup base 4. The inner wall of the seedling-raising cup cover 3 is in close contact with the outer wall of the seedling-raising cup base 4.

[0021] The nutrient soil falls into the seedling-raising cup cover 3 and the seedling-raising cup base 4 through the seedling-raising holes. The seedling-raising cup cover 3 is located above the seedling-raising cup base 4. The internal form after the seedling-raising cup cover 3 and the seedling-raising cup base 4 are connected can be seen. Figure 7 When the seeds of loofah germinate and the seedlings grow 2 - 3 true leaves, the seedlings and the nutrient soil can be dug out of the seedling-raising cup together and then transplanted into the land. First, the user can press the two side edges of the main body 1 of the seedling-raising tray downward with both hands. The bottom of the seedling-raising cup base 4 contacts the ground. When pressing the main body 1 of the seedling-raising tray, the main body 1 of the seedling-raising tray will drive the seedling-raising cup cover 3 to move downward. Both the seedling-raising cup cover 3 and the seedling-raising cup base 4 are made of hard plastic and will not easily deform; Since the seedling-raising cup cover 3 is larger than the seedling-raising cup base 4, when connecting the seedling-raising cup cover 3 and the seedling-raising cup base 4, first put the seedling-raising cup base 4 into the seedling-raising cup cover 3 from above the seedling-raising cup cover 3. Figure 3 As can be seen in Both the top of the nutrient soil and the main body 1 of the seedling-raising tray are parallel. After pressing the main body 1 of the seedling-raising tray and the main body 1 of the seedling-raising tray drives the seedling-raising cup cover 3 to move downward, a part of the nutrient soil will be exposed and protrude above the top of the seedling-raising holes. The exposed nutrient soil accounts for about 1 / 3 of its own height. The seedling-raising cup cover 3 releases the wrapping pressure on a part of the nutrient soil area, and a grasping point is formed after the area originally covered by the seedling-raising cup cover 3 is exposed; In Figure 4 As can be seen, the two strip-shaped openings 5 are respectively opened on two surfaces of the seedling-raising cup base 4, and the two strip-shaped openings 5 are horizontally corresponding and then Figure 5 and Figure 6As can be seen from the perspective of Figure 11 From the perspective of When the seedling-raising cup cover 3 moves downward, it will pull both ends of the supporting belt 6 to move downward together. The two ends of the supporting belt 6 move downward with the seedling-raising cup cover 3 towards the lower part outside the seedling-raising cup base 4. At the same time, the area of the supporting belt 6 located inside the seedling-raising cup base 4 will also continuously pass through the strip-shaped opening 5 and be pulled towards the outside of the seedling-raising cup base 4. Then, the area where the supporting belt 6 hangs down inside the seedling-raising cup base 4 will gradually move closer upward. Since a part of the area of the supporting belt 6 is laid on the inner bottom wall of the seedling-raising cup base 4 when the supporting belt 6 hangs down, the nutrient soil is on the supporting belt 6. When the supporting belt 6 gradually moves closer upward, the supporting belt 6 will push the nutrient soil upward, causing a part of the area of the nutrient soil located inside the seedling-raising cup base 4 to move upward; Part of the area of the nutrient soil moves upward out of the seedling-raising cup base 4, reducing the contact area with the seedling-raising cup base 4, and the resistance of the nutrient soil being wrapped by the seedling-raising cup base 4 will also be smaller. And when the supporting belt 6 is pulled out, it is in a straightened state, so it is even less likely to easily form wrinkles and squeeze the nutrient soil. In this way, when taking out the nutrient soil, the roots are more likely to break away from the inside of the seedling-raising cup base 4 together with the soil mass as a whole, further retaining the "root-protecting soil" around the roots and reducing root damage during transplantation; The seedling-raising cup is set in a shape that is wider at the top and narrower at the bottom, with rounded edges at the corners. The top of the seedling-raising cup cover 3 is parallel to the top of the seedling-raising tray main body 1 and the top of the seedling-raising holes. The overall shape of the seedling-raising cup cover 3 and the seedling-raising cup base 4 is a frustum-shaped structure that is wider at the top and narrower at the bottom. First of all, this shape can guide the roots to grow naturally downward, reducing coiling and entanglement. Secondly, the cup wall of the frustum-shaped structure is inclined. When the nutrient soil is filled in, the contact area with the cup wall decreases with the increase in height (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 upper part is significantly reduced, and the overall demolding requires less external force; Moreover, the inclined cup wall forms a "draft angle" similar to mold demolding. Under the action of gravity or external force, the soil will naturally slide out along the inclined surface, avoiding the "vacuum adsorption" or "jamming" phenomenon caused by a vertical cup wall; Secondly, for the rounded-edge setting of the seedling-raising cup cover 3 and the seedling-raising cup base 4, the rounded-edge eliminates the stress concentration points of the right-angled cup wall, reduces the embedding of soil particles at the corners, the inclined wall surface makes the pressure distribution between the soil and the cup wall more uniform, which can reduce the risk of local adhesion. And the rounded-edge can also avoid sharp corners from scratching the roots and reduce mechanical damage during transplantation.

[0022] Refer to Figures 1 - 9, the inner bottom wall of the seedling-raising cup base 4 is provided with a first bottom surface 401 and a second bottom surface 402, and there is a height difference at the boundary between the two, forming a stepped surface; The supporting belt 6 is provided with a strip-shaped water drain opening 9 running through it, and the strip-shaped water drain opening 9 extends along the boundary line direction between the first bottom surface 401 and the second bottom surface 402. The center line in the extending direction of the strip-shaped water drain opening 9 and the boundary line between the two bottom surfaces are in the same longitudinal plane.

[0023] The strip-shaped water drain opening 9 is long and strip-shaped. From Figure 6 the perspective, it can be seen that the center of the strip-shaped water drain opening 9 is directly opposite the boundary between the first bottom surface 401 and the second bottom surface 402. From Figure 6 the perspective, when the supporting belt 6 naturally hangs in the seedling-raising cup base 4, part of the area of the supporting belt 6 lies on the inner bottom wall of the seedling-raising cup base 4. The left side of the strip-shaped water drain opening 9 is on the second bottom surface 402, and the right side of the strip-shaped water drain opening 9 is on the first bottom surface 401; When the supporting belt 6 is covered with nutrient soil, the weight of the nutrient soil will exert pressure on the supporting belt 6. At this time, the left side of the strip-shaped water drain opening 9 will be close to the top of the second bottom surface 402, and the right side of the strip-shaped water drain opening 9 will be close to the top of the first bottom surface 401. Since the heights of the first bottom surface 401 and the second bottom surface 402 are different, the left and right sides of the strip-shaped water drain opening 9 are also at different heights. At this time, the left and right sides of the strip-shaped water drain opening 9 will show an up-and-down staggered phenomenon. Since the left and right sides of the strip-shaped water drain opening 9 are up-and-down staggered, the strip-shaped water drain opening 9 is in an open state at this time, and then the excess water in the soil can directly flow out through the strip-shaped water drain opening 9; Then when the two ends of the supporting belt 6 are pulled downward, the supporting belt 6 is pulled, causing the area near the supporting belt 6 and the strip-shaped water drain opening 9 to move upward and close together. At this time, the soil pressure on both sides of the strip-shaped water drain opening 9 is relatively uniform, and there is no limit from the first bottom surface 401 and the second bottom surface 402. Therefore, at this time, the suspended strip-shaped water drain opening 9 is no longer staggered, and the left and right sides of the strip-shaped water drain opening 9 are also at the same level. At this time, the strip-shaped water drain opening 9 is in a closed state. Although there will still be a gap in the closed strip-shaped water drain opening 9, the gap in the closed strip-shaped water drain opening 9 is very thin, and the soil will not easily fall out from the strip-shaped water drain opening 9 at this time; This can prevent part of the soil from falling out through the strip-shaped water drain opening 9 when the soil is pushed out.

[0024] Refer to Figures 4 - 10 , it also includes a drain opening 403, which is arranged on the stepped surface of the boundary line between the first bottom surface 401 and the second bottom surface 402, and the drain opening 403 communicates with the outside.

[0025] First, the drain opening 403 is provided at the bottom of the seedling-raising cup base 4, which serves an important purpose. During the seedling-raising process, appropriate watering is crucial for the growth of seedlings. If there is no drain opening 403, when too much water is poured, the water will accumulate inside the cup, causing the soil to be overly wet and affecting the air permeability of the soil. The drain opening 403 can allow the excess water to be discharged in a timely manner, preventing waterlogging from causing problems such as root rot and hypoxia, and creating a suitable humidity environment for the roots of the seedlings. Since the nutrient soil is on the supporting belt 6, the strip-shaped drain opening 9 provided on the supporting belt 6 corresponds to the drain opening 403, so that the excess water can flow to the position of the drain opening 403 through the strip-shaped drain opening 9 and then flow to the outside from the drain opening 403. The center of the strip-shaped drain opening 9 is directly opposite the boundary line between the first bottom surface 401 and the second bottom surface 402. From Figure 9 this perspective, one side of the drain opening 403 corresponds to the second bottom surface 402, and the position of the drain opening 403 is on the side wall where the first bottom surface 401 contacts the second bottom surface 402. At this time, the open strip-shaped drain opening 9 is directly opposite the drain opening 403, and then the excess water in the soil can directly flow to the drain opening 403 through the strip-shaped drain opening 9.

[0026] Refer to Figures 3 - 10 , a strip-shaped through groove 11 is provided at the bottom of the seedling-raising cup base 4. The strip-shaped through groove 11 is directly below the boundary line between the first bottom surface 401 and the second bottom surface 402. The bottom of the strip-shaped through groove 11 communicates with the outside, and the top of the strip-shaped through groove 11 communicates with the inside of the drain opening 403. A counterweight bar 12 is provided inside the strip-shaped through groove 11. The bottom of the counterweight bar 12 is parallel to the bottom of the seedling-raising cup base 4. The top of the counterweight bar 12 abuts against the inner top wall of the strip-shaped through groove 11. Two connecting blocks 13 are fixedly connected between the top of the counterweight bar 12 and the inner top wall of the drain opening 403.

[0027] After the soil is placed in the seedling-raising cup, the position of the main body 1 of the seedling-raising tray needs to be moved. After the main body 1 of the seedling-raising tray is lifted, since the bottom of the seedling-raising cup base 4 is in a suspended state, some soil will fall out from the drain opening 403. When the seedling-raising cup base 4 touches the ground, the bottom of the counterweight bar 12 will also touch the ground. At this time, the counterweight bar 12 is located inside the strip-shaped through groove 11. When the outer wall of the counterweight bar 12 fits with the inner wall of the strip-shaped through groove 11, the bottom of the counterweight bar 12 is the same as the bottom of the seedling-raising cup base 4 and also touches the ground. When the main body 1 of the seedling-raising tray is lifted, at this time the bottom of the seedling-raising cup base 4 is in a suspended state. Since the weight of the counterweight bar 12 is greater than that of the seedling-raising cup base 4 but the weight does not exceed the weight of the overall main body 1 of the seedling-raising tray, after the bottom of the seedling-raising cup base 4 is suspended, the counterweight bar 12 will fall downward, and the downward-falling counterweight bar 12 will pull the inner top wall of the drain opening 403 to approach the top surface of the second bottom surface 402 through the connecting block 13. After the top surface of the drain opening 403 is close to the edge of the top surface of the second bottom surface 402, the inlet on the side of the drain opening 403 is in a closed state at this time. In this way, when the main body 1 of the seedling tray is lifted and the bottom of the seedling cup holder 4 is in a suspended state, there will be no situation where some soil falls out from the drain opening 403; It is worth adding that the weight of the counterweight bar 12 can only pull the inner top wall of the drain opening 403 to be close to the edge of the second bottom surface 402, and will not deform the entire seedling cup holder 4. Therefore, the specific weight of the counterweight bar 12 can be determined according to the material strength of the seedling cup holder 4.

[0028] Refer to Figures 6 - 10 , the bottom of the seedling cup holder 4 has elasticity, and the outer shape of the counterweight bar 12 is adapted to the strip-shaped through groove 11.

[0029] The bottom of the seedling cup holder 4 has a certain elasticity, so that the inner top wall of the drain opening 403 can deform downward. The counterweight bar 12 is adapted to the strip-shaped through groove 11. In this way, when the bottom of the seedling cup holder 4 touches the ground, the counterweight bar 12 will also touch the ground, and then the counterweight bar 12 will be stuck into the strip-shaped through groove 11. Furthermore, the bottom of the counterweight bar 12 is parallel to the bottom of the seedling cup holder 4, which can ensure the overall flat state.

[0030] Refer to Figures 3 - 8 , a first inclined surface 7 is provided on the contact surface between the seedling cup holder 4 and the seedling cup cover 3, a second inclined surface 10 is provided on the contact surface between the seedling cup cover 3 and the first inclined surface 7, the outer walls of the first inclined surface 7 and the second inclined surface 10 are in contact with each other, and the lower inclined ends of the second inclined surface 10 and the first inclined surface 7 correspond to the outside of the seedling cup holder 4.

[0031] From Figure 7 's perspective, the contact surface between the seedling cup cover 3 and the seedling cup holder 4 is provided as the second inclined surface 10, the surface of the seedling cup holder 4 in contact with the second inclined surface 10 is provided as the first inclined surface 7, the surfaces of the second inclined surface 10 and the first inclined surface 7 are in contact and fit with each other, and the lower inclined ends of the first inclined surface 7 and the second inclined surface 10 both face the periphery of the seedling cup holder 4. In this way, when the seedling cup cover 3 is squeezed by the main body 1 of the seedling tray, it will slide downward 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 holder 4, and it will not exert an extrusion force on the nutrient soil, avoiding the extrusion of the main root by the cup wall folds, and also avoiding problems such as root damage and soil block fragmentation in the traditional method. At the same time, the transplanting efficiency and success rate are significantly improved. At the same time, pressing the main body 1 of the seedling tray can release the nutrient soil in multiple seedling cups at one time, and the batch operation reduces the single-plant processing time, and the whole tray of seedlings can be transplanted quickly.

[0032] Refer to Figures 4 - 11, further comprising a groove 8 which is circumferentially arranged on the outer wall of the seedling-raising cup seat 4 around the circumference of the seedling-raising cup seat 4, and the groove 8 is communicated with the first inclined surface 7; a convex block 14 which is circumferentially connected to the inner wall of the seedling-raising cup cover 3 around the circumference of the seedling-raising cup cover 3, the bottom of the convex block 14 is fixedly connected to the top of the second inclined surface 10, and the top of the convex block 14 abuts against the inner top wall of the groove 8; The strip-shaped opening 5 is communicated with the inside of the groove 8, and the strip-shaped opening 5 corresponds to a part of the area of the convex block 14. The two ends of the supporting belt 6 respectively pass through the two strip-shaped openings 5 and are fixedly connected to the outer wall of the convex block 14.

[0033] The groove 8 is formed on the outer wall of the seedling-raising cup seat 4 and is located at the top of the first inclined surface 7. As can be seen in Figure 4 , the groove 8 is recessed in the seedling-raising cup seat 4, and the convex block 14 is fixed on the inner wall of the seedling-raising cup cover 3. As can be seen in Figure 11 , the convex block 14 protrudes from the inner wall of the seedling-raising cup cover 3. When the first inclined surface 7 abuts against the second inclined surface 10, the convex block 14 is stuck in the groove 8. The top of the convex block 14 is flat, and the inner top wall of the groove 8 is also flat. Therefore, the top surface of the convex block 14 abuts against the inner top wall of the groove 8. In this way, when the seedling-raising tray main body 1 is lifted, the seedling-raising cup cover 3 can hook the groove 8 through the convex block 14, and then lift the seedling-raising cup seat 4 together; Although the top of the seedling-raising cup seat 4 can be stuck in the seedling-raising cup cover 3, the seedling-raising cup cover 3 has a certain elasticity. After the seedling-raising cup seat 4 is filled with nutrient soil, the weight of the seedling-raising cup seat 4 will increase. Therefore, when the seedling-raising tray main body 1 is lifted, the heavier seedling-raising cup seat 4 may slide down from the bottom of the seedling-raising cup cover 3. Through the clamping connection between the convex block 14 and the groove 8, it is possible to prevent the seedling-raising cup seat 4 from falling out of the seedling-raising cup cover 3 downward.

[0034] Refer to Figure 2 , a plurality of ribs 2 are fixedly connected to the inner wall of the seedling-raising tray main body 1, and the ribs 2 are distributed among a plurality of seedling-raising holes.

[0035] After the seedling-raising tray main body 1 is filled with nutrient soil, its weight is relatively large. The ribs 2 can increase the rigidity of the tray body, reduce bending or depression caused by its own weight or external forces such as handling and stacking. And when pressing down the seedling-raising tray main body 1 to make the seedling-raising cup cover 3 move downward along the seedling-raising cup seat 4, if the seedling-raising tray main body 1 is deformed and bent, it will cause some of the seedling-raising cup covers 3 not to be pressed and moved downward. The ribs 2 improve the strength of the seedling-raising tray main body 1, so that when the seedling-raising tray main body 1 is lifted or pressed downward, it can remain relatively flat as a whole, ensuring that the seedling-raising cup cover 3 moves downward synchronously and evenly along the seedling-raising cup seat 4, and preventing some of the seedling-raising cup covers 3 from not being pressed down due to the deformation of the seedling-raising tray main body 1; Secondly, the ribs 2 are distributed among a plurality of seedling-raising holes to form a support network, dispersing the pressure to the entire tray body and avoiding stress concentration.

[0036] Refer to Figures 1 - 11 , the present invention also provides a usage method, which is applied to the loofah seedling raising device of any of the above embodiments. The main body 1 of the seedling tray further includes Step 1, assembly: Insert the seedling cup base 4 into the seedling cup cover 3. Then place the supporting belt 6 in the seedling cup base 4, and respectively pass the two ends of the supporting belt 6 through the two strip-shaped openings 5 and adhere them to the seedling cup cover 3; Step 2, sowing: Fill the prepared nutrient soil into the seedling cups, gently compact it, and evenly spray water on the seedling cups with a watering can or a sprayer to make the substrate fully moist but without waterlogging. According to the size and characteristics of the seeds, adopt different sowing methods. After sowing, gently cover a thin layer of substrate, and the thickness should be just enough to cover the seeds; Step 3, separation: After germination, press the main body 1 of the seedling tray and the seedling cup cover 3. While the seedling cup cover 3 moves downward, pull the supporting belt 6 to move upward and close together, and then use the supporting belt 6 to lift the soil out to realize the separation of the nutrient soil and the seedling cup.
