Description

Technical Field

[0001] This invention belongs to the field of agricultural seedling equipment technology, specifically a light-absorbing seedling tray for agricultural seed cultivation. Background Technology

[0002] During the breeding and seedling raising process, the seed germination stage has high requirements for the temperature and humidity of the culture soil. In order to increase the heat required for seed germination, breeders usually use light-absorbing seedling trays. These seedling trays are laid flat on the seedling greenhouse or flat outdoor ground. Their surface is coated with a black coating or made of light-absorbing material. Under sunlight, they absorb light and heat and conduct the heat to the culture soil inside the seedling tray. Breeders then sow the treated seeds in each seedling hole of the seedling tray, cover them with soil, and water them to keep the seeds in a warm and humid culture environment to complete the germination process.

[0003] After the seeds sprout and seedlings emerge, the seedlings' environmental requirements change. Newly emerged seedlings are very delicate; if the surface of the seedling tray continues to absorb strong light, the temperature in the upper part of the seedling hole will rise, affecting the root-stem junction and increasing the risk of seedling diseases. The continuous high temperature and confined environment also make it difficult for moisture in the potting soil to escape, affecting the normal growth of the seedling roots. After the initial covering and watering, the surface layer of potting soil in the seedling hole may also become compacted, hindering air from entering the soil and impeding root respiration. Current technologies address the issues of cooling, moisture removal, and soil loosening after emergence. Typically, this method relies on manual intervention. During the concentrated germination stage, growers replace the light-absorbing seedling trays with ordinary breathable seedling trays, or erect shading structures above the seedling trays and manually loosen the surface soil. This approach requires a significant investment of manpower and time, and is inefficient in large-scale seedling production. Since different seeds in the same seedling tray have different germination times, uniform replacement or shading cannot simultaneously meet the needs of unemerged seeds for light absorption, heat preservation, and high humidity for germination, as well as the needs of emerged seedlings for light penetration, cooling, ventilation, dehumidification, and surface soil loosening. This affects the overall germination and survival rate of the seeds in the seedling trays. Summary of the Invention

[0004] In view of the above-mentioned problems in the prior art, the purpose of the present invention is to provide a light-absorbing seedling tray for agricultural seed cultivation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A light-absorbing seedling tray for agricultural seed cultivation includes a seedling tray, a seedling hole, a cover plate, a triggering component, a switching component, and an auxiliary component, wherein the triggering component includes a plate body connected to the cover plate; The switching component includes a third groove disposed on the seedling tray, and a block is provided inside the third groove; The auxiliary component has a second hole opened in the seedling tray, a second rod is provided in the second hole, the second rod is connected to the block, and a third hole is opened on the seedling tray; When the cover plate is moved by the seedling, it causes the plate to swing. The block moves to switch the light absorption state of the seedling tray and simultaneously drives the second rod to move the surface soil in the seedling hole, while opening the third hole.

[0006] Preferably, the triggering component further includes a seat on the seedling tray, the plate being mounted on the seat, and the plate gradually moving away from the opening of the seedling hole from one end near the cover plate to the other end near the seat.

[0007] Preferably, the plate has a second groove, the seedling tray has a seat, and the seat has a first elastic element, which cooperates with the second groove to position the plate.

[0008] Preferably, the third groove is provided with a second elastic element, which is connected to the block. When the block is restricted, the second elastic element is in a tensile energy storage state. After the block is released from restriction, it is pulled by the second elastic element and moves along the third groove.

[0009] Preferably, the block is provided with a light-absorbing area and a light-reflecting area. Before the block is moved, the light-absorbing area is brought close to the opening of the seedling hole, and after the block is moved, the light-reflecting area is brought close to the opening of the seedling hole.

[0010] Preferably, the plate has a first groove, the seedling tray has a first hole, a first rod is slidably disposed in the first hole, the first rod has a first insertion part, the first insertion part is inserted into the first groove, the first rod also has a second insertion part, and the block has a fourth groove, the second insertion part is inserted into the fourth groove.

[0011] Preferably, the block has a fourth groove, the fourth groove has a limiting section for restricting the movement of the block, the fourth groove also has a driving section communicating with the limiting section, and the fourth groove also has a holding section communicating with the driving section, the driving section gradually moving away from the inside of the seedling tray along the movement path of the block.

[0012] Preferably, the block is provided with a baffle, the third hole has a connection point that communicates with the third groove, the baffle blocks the connection point before the block moves, and the baffle leaves the connection point after the block moves.

[0013] Preferably, one end of the second hole is connected to the side area of ​​the seedling hole near the opening, and the other end of the second hole is connected to the third groove. The end of the second rod extending into the seedling hole is a rounded end, and the end of the second rod extending into the seedling hole maintains a distance from the middle area of ​​the seedling hole.

[0014] Preferably, the plate has a first groove, the block has a fourth groove, and the seedling tray has a first hole. A first rod is slidably disposed in the first hole. One end of the first rod engages with the first groove, and the other end engages with the fourth groove. When the cover is supported by the seedling, the plate moves the first rod, causing the first rod to release its obstruction of the block. After the block moves, the fourth groove pushes the first rod to continue moving, keeping the cover open.

[0015] The beneficial effects of this invention are as follows: I. In this invention, the supporting effect generated after the seedlings break through the soil can trigger the seedling tray to switch from the germination and heat preservation state to the seedling ventilation state. During the germination stage, the seedling hole is in a covered and light-absorbing state, which can reduce moisture loss and improve the heating effect of the potting soil, meeting the temperature and humidity requirements of seed germination. During the seedling stage, the supporting effect of the seedlings drives the movement of the corresponding structure, which causes the light absorption state of the seedling tray to switch, and simultaneously moves the surface potting soil and opens the ventilation channel. The area where the seedlings have emerged can reduce continuous heat absorption, the moisture in the seedling hole can be discharged outward, and the surface potting soil can form a loose area. This takes into account the heat preservation and moisture retention requirements of the seeds that have not yet emerged, as well as the cooling, dehumidification, and ventilation requirements of the seedlings that have emerged. At the same time, it reduces the impact caused by the lag of manual replacement of seedling trays, uniform shading, and manual loosening of soil. Second, in this invention, the seedling's own emergence action is used as the trigger source, and the actions of light change, soil loosening and ventilation are completed through the same movement process, so that multiple maintenance actions are coordinated. It does not rely on electronic control detection and external power drive, and is suitable for use in scenarios with a large number of seedling trays. It can reduce the workload of manual inspection and hole-by-hole treatment, and improve the adaptability of seeds with different emergence progress in the same seedling tray.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] Please see Figure 1 and Figure 2 A light-absorbing seedling tray for agricultural seed cultivation includes a seedling tray 1, seedling holes 2, a cover plate 3, a triggering component 4, a switching component 5, and an auxiliary component 6. The seedling holes 2 are located in the middle of the seedling tray 1, the cover plate 3 is arranged at the opening of the seedling holes 2, the triggering component 4 is connected to one side of the cover plate 3, the switching component 5 is arranged on the light-facing side of the seedling tray 1 and inside the seedling tray 1, and the auxiliary component 6 is arranged on the side of the seedling tray 1 near the seedling holes 2.

[0020] It should be noted that, in combination Figure 1 and Figure 2In this embodiment, the light-facing surface of the seedling tray 1 is the bearing surface for installing the trigger component 4 and the switching component 5. The seedling hole 2 is used to contain the potting soil and seeds. The cover plate 3 is used to cover the opening of the seedling hole 2. The trigger component 4 is used to receive the top support force transmitted by the cover plate 3. The switching component 5 is used to switch between the light absorption state and the light reflection state. The auxiliary component 6 is used to cooperate with the switching component 5 to complete the stirring of the surface potting soil and the ventilation of the seedling hole 2.

[0021] like Figures 1 to 3 As shown, the seedling tray 1 is preferably made of plastic. The seedling tray 1 is a plate-shaped tray with a central area for placing the potting soil. It also has a support area for installing the trigger component 4 and the switching component 5. The thickness of the seedling tray 1 is sufficient to accommodate the seedling holes 2, the first hole 54, the second hole 61, and the third hole 63. The seedling holes 2 are located in the center of the seedling tray 1 and are recessed into the tray 1 from the light-facing side. The inner wall of the seedling holes 2 restricts the flow of potting soil into the seedling tray. 1. Externally distributed, the area near the opening of the seedling hole 2 is used to contain the top layer of potting soil, and the area away from the opening of the seedling hole 2 is used to contain the growth space of the seed roots. The cover plate 3 is preferably made of transparent plastic. The cover plate 3 is a thin plate-shaped component. The area of ​​the cover plate 3 is larger than the area of ​​the opening of the seedling hole 2. The cover plate 3 covers the opening of the seedling hole 2. The cover plate 3 is used to reduce the loss of water in the seedling hole 2. The cover plate 3 is also used to receive the pushing force generated by the seedling breaking through the soil. After the cover plate 3 is supported by the seedling, it can drive the trigger component 4 to move.

[0022] like Figures 3 to 5 As shown, the triggering component 4 includes a plate 41, a seat 42, and a first elastic element 421. One end of the plate 41 is fixedly connected to the cover plate 3, and the other end of the plate 41 is rotatably connected to the seat 42. The seat 42 is fixedly connected to the light-facing surface of the seedling tray 1. The first elastic element 421 is disposed inside the seat 42. The plate 41 is preferably made of plastic and is a strip. The plate 41 gradually moves away from the opening of the seedling hole 2 from the end near the cover plate 3 to the end near the seat 42. The plate 41 is fixedly connected to the cover plate 3. Afterwards, the cover plate 3 is lifted by force, which can drive the plate 41 to swing synchronously. A first groove 411 is provided in the middle of the plate 41. The first groove 411 penetrates the plate 41. The first groove 411 is an elongated oval groove. The first groove 411 extends along the length of the plate 41. The first groove 411 is used to accommodate the first insertion part 551. A second groove 412 is provided near the seat 42 of the plate 41. The second groove 412 is an arc-shaped groove. The second groove 412 is used to accommodate the end of the steel ball of the first elastic member 421.

[0023] like Figures 4 to 7As shown, the seat 42 is preferably made of plastic. The seat 42 is a rotating seat fixed to the light-facing side of the seedling tray 1. The seat 42 has a rotating shaft inside. The end of the plate 41 away from the cover plate 3 is sleeved on the rotating shaft of the seat 42. The plate 41 can swing around the rotating shaft of the seat 42. The seat 42 also has a mounting hole inside, which faces the plate 41. The first elastic element 421 is set in the mounting hole. The first elastic element 421 cooperates with the second groove 412 through the mounting hole. The first elastic element 421 includes a compression spring and a steel ball. The compression spring is preferably made of spring steel, and the steel ball is preferably made of stainless steel. A part of the steel ball extends out of the mounting hole of the seat 42. When the cover plate 3 covers the opening of the seedling hole 2, the steel ball extends into the second groove 412 under the action of the spring. After the steel ball cooperates with the second groove 412, it positions the plate 41. After the plate 41 is positioned, the cover plate 3 remains in the state of covering the opening of the seedling hole 2.

[0024] When using, combine Figure 2 , Figures 4 to 7 After the seedlings break through the soil, they apply a supporting force to the cover plate 3. The cover plate 3 transmits this supporting force to the plate 41. The plate 41 swings around the pivot of the base 42. When the plate 41 swings, the groove wall of the second groove 412 pushes the steel ball. The steel ball pushes the compression spring and retracts into the mounting hole of the base 42. After the steel ball exits the second groove 412, the plate 41 is released from its position, and the cover plate 3 can continue to open the opening of the seedling hole 2 with the plate 41.

[0025] like Figure 3 and Figure 4 As shown, the switching component 5 includes a third groove 51, a block 52, a second elastic element 53, a first hole 54, and a first rod 55. The third groove 51 is located on the light-facing surface of the seedling tray 1. The block 52 is slidably connected within the third groove 51. The second elastic element 53 is disposed within the third groove 51. The first hole 54 is located within the seedling tray 1. The first rod 55 is slidably connected within the first hole 54. The third groove 51 is a long, narrow groove that extends along the length of the seedling tray 1. The opening of the third trough 51 is located on the light-facing side of the seedling tray 1. The bottom of the third trough 51 is used to support the block 52. The wall of the third trough 51 is used to guide the block 52 to slide along the third trough 51. One end of the third trough 51 is used to connect to the second elastic element 53. The other end of the third trough 51 is used to accommodate the moved block 52. The side of the third trough 51 near the seedling hole 2 is connected to the second hole 61. The position of the third trough 51 near the third hole 63 is used to accommodate the movement of the baffle 524.

[0026] like Figure 3 and Figure 4As shown, the block 52 is preferably made of plastic and is a long strip-shaped slider. The block 52 is set in the third groove 51 and can slide along the third groove 51. The side of the block 52 facing the light is provided with a light-absorbing area 521 and a reflective area 522. The light-absorbing area 521 is located in one section of the side of the block 52 facing the light, and the reflective area 522 is located in the other section of the side of the block 52 facing the light. The light-absorbing area 521 is preferably coated with a black heat-absorbing coating, and the reflective area 522 is preferably coated with a light-colored reflective coating. When the block 52 is in the initial position, the light-absorbing area 521 is close to the opening of the seedling hole 2 and is used to absorb light and heat and provide heat to the vicinity of the seedling hole 2. When the block 52 is moved to the release position, the reflective area 522 is close to the opening of the seedling hole 2 and is used to reduce heat absorption near the seedling hole 2.

[0027] like Figure 4 , Figure 8 and Figure 9 As shown, a fourth groove 523 is provided on the side of the block 52 near the seedling hole 2. The fourth groove 523 includes a limiting section, a driving section, and a holding section. The limiting section extends along the thickness of the seedling tray 1. The driving section is connected to the limiting section and gradually moves away from the inside of the seedling tray 1 along the moving path of the block 52 being pulled by the second elastic member 53. The holding section is connected to the driving section and is set along the extension path of the third groove 51. The limiting section is used to accommodate the second insertion part 552. The driving section is used to push the second insertion part 552 when the block 52 moves. The holding section is used to accommodate the second insertion part 552 after the block 52 has moved into place. A baffle 524 is fixedly connected to the bottom of the block 52. The baffle 524 is preferably made of plastic and is a rectangular thin plate. The baffle 524 moves synchronously with the block 52. The area of ​​the baffle 524 is larger than the opening area at the connection between the third hole 63 and the third groove 51. When the block 52 is in the initial position, the baffle 524 is located at the connection between the third hole 63 and the third groove 51, and the baffle 524 blocks the connection. When the block 52 moves to the release position, the baffle 524 leaves the connection with the block 52. After the connection is opened, the third hole 63 can connect the outside of the seedling hole 2 and the seedling tray 1.

[0028] like Figure 3As shown, the second elastic element 53 is preferably a tension spring, preferably made of spring steel. The second elastic element 53 is disposed in the third groove 51. One end of the second elastic element 53 is fixedly connected to the groove wall of the third groove 51, and the other end of the second elastic element 53 is fixedly connected to the block 52. When the block 52 is in the initial position, the second elastic element 53 is stretched. After being stretched, the second elastic element 53 has an elastic force to pull the block 52. When the second insertion part 552 is not released from the limit, the block 52 is blocked by the second insertion part 552, and the second elastic element 53 cannot pull the block 52 to move. After the second insertion part 552 is released from the limit, the second elastic element 53 pulls the block 52 to move along the third groove 51.

[0029] like Figure 3 As shown, the first hole 54 is formed on the seedling tray 1. The first hole 54 is located between the seedling hole 2 and the third groove 51. The first hole 54 extends along the thickness of the seedling tray 1. The end of the first hole 54 near the plate 41 is adjacent to the first groove 411, and the end of the first hole 54 near the block 52 is adjacent to the fourth groove 523. The inner wall of the first hole 54 is provided with a keyway. The keyway is set along the extension path of the first hole 54 and is used to cooperate with the shaft key on the first rod 55.

[0030] like Figure 3 , Figure 4 , Figure 8 and Figure 9As shown, the first rod 55 is preferably made of plastic. The first rod 55 is a rod-shaped component and is slidably connected within the first hole 54. A key is provided on the outer side of the first rod 55, extending into a keyway on the inner wall of the first hole 54. The key and keyway engage to restrict the rotation of the first rod 55, allowing it to slide along the first hole 54. The end of the first rod 55 closest to the plate 41 engages with the plate 41. The end of the first rod 55 closest to the block... One end of 52 engages with block 52. The first rod 55 has a first insertion part 551 near the end of plate 41. The first insertion part 551 is a rod-shaped protrusion that extends into the first groove 411 of plate 41. The first insertion part 551 can slide within the first groove 411. When plate 41 swings around base 42, the position of the first groove 411 changes with plate 41, and the groove wall of the first groove 411 pushes against the first insertion part 551. When the first insertion part 551 is pushed, it drives the first rod 55 to move along the first hole 54 away from the inside of the seedling tray 1. The first rod 55 has a second insertion part 552 at the end near the block 52. The second insertion part 552 is a rod-shaped protrusion that extends into the fourth groove 523 of the block 52. In the initial state, the second insertion part 552 is located in the limiting section of the fourth groove 523. The second elastic member 53 pulls the block 52. When the wall of the limiting section abuts against the second insertion part 552, the second insertion part 552 is supported in the first hole 54 by the first rod 55. After the block 52 is blocked by the second insertion part 552, it cannot move along the third groove 51. After the plate 41 swings and drives the first rod 55 to move, the second insertion part 552 moves from the blocking position of the limiting section to the entrance of the driving section. The block 52 is blocked and the second elastic member 53 can pull the block 52 to move.

[0031] When using, combine Figures 3 to 9 After the cover plate 3 is supported by the seedling, it causes the plate body 41 to swing. The plate body 41 pushes against the first insertion part 551 through the first groove 411. The first insertion part 551 drives the first rod body 55 to move. The first rod body 55 drives the second insertion part 552 to leave the limiting section of the fourth groove 523. The second insertion part 552 no longer blocks the block 52. The second elastic member 53 pulls the block 52 to move along the third groove 51. After the block 52 moves, the light-absorbing area 521 leaves the area near the opening of the seedling hole 2, and the reflective area 522 moves to the area near the opening of the seedling hole 2. This combination is used to switch the seedling hole 2 from the light-absorbing and heat-gathering state to the reflective and cooling state.

[0032] like Figure 3 , Figure 10 and Figure 11As shown, the auxiliary component 6 includes a second hole 61, a second rod 62, and a third hole 63. The second hole 61 is opened inside the seedling tray 1, the second rod 62 is slidably connected inside the second hole 61, and the third hole 63 is opened inside the seedling tray 1. The second hole 61 is a transverse through hole. One end of the second hole 61 is connected to the side area of ​​the seedling hole 2 near the opening, and the other end of the second hole 61 is connected to the third groove 51. The diameter of the second hole 61 is larger than the diameter of the second rod 62. The second hole 61 is used to provide sliding space for the second rod 62. The second hole 61 is also used to limit the movement path of the second rod 62, so that the second rod 62 moves along the side area of ​​the seedling hole 2 near the opening.

[0033] like Figure 3 , Figure 8 , Figure 10 and Figure 11 As shown, the second rod 62 is preferably made of plastic. The second rod 62 is a slender rod and is slidably connected inside the second hole 61. One end of the second rod 62 is fixedly connected to the block 52, and the other end of the second rod 62 extends into the side area of ​​the seedling hole 2 near the opening. The end of the second rod 62 extending into the seedling hole 2 is a blunt end. The end of the second rod 62 extending into the seedling hole 2 maintains a distance from the middle area of ​​the seedling hole 2. When the block 52 moves along the third groove 51, the block 52 drives the second rod 62 to move along the second hole 61. When the second rod 62 moves, it disturbs the surface layer of culture soil near the opening of the seedling hole 2. After the surface layer of culture soil is disturbed, it forms a loose area. After the second rod 62 maintains a distance from the middle area of ​​the seedling hole 2, the second rod 62 avoids the seedling emergence position when it moves.

[0034] like Figure 3 , Figure 10 and Figure 11 As shown, the third hole 63 is a ventilation hole. The third hole 63 is located inside the seedling tray 1. One end of the third hole 63 is connected to the area of ​​the seedling hole 2 away from the open end, and the other end of the third hole 63 is connected to the outside of the seedling tray 1. The third hole 63 has a connecting point near the third trough 51. This connecting point is connected to the third trough 51. The baffle 524 is slidably disposed in this connecting point. When the block 52 is in the initial position, the baffle 524 blocks the connecting point, and the seedling hole 2 is isolated from the outside of the seedling tray 1 through the third hole 63. When the block 52 moves to the release position, the baffle 524 leaves the connecting point, and the seedling hole 2 is connected to the outside of the seedling tray 1 through the third hole 63.

[0035] It should be noted that, in combination Figure 8The second rod 62 and the baffle 524 are directly connected to the block 52. When the block 52 is pulled by the second elastic element 53, the second rod 62 and the baffle 524 move synchronously with the block 52. The second rod 62 is used to agitate the surface culture soil, and the baffle 524 is used to open the third hole 63. One movement of the block 52 can simultaneously complete the reflection switching, agitate the culture soil and open the ventilation hole.

[0036] The following is the working principle of this embodiment: Preparation stage, combined with Figures 1 to 7 The potting soil and seeds are placed in the seedling hole 2, and the cover plate 3 covers the opening of the seedling hole 2. The steel ball of the first elastic element 421 is inserted into the second groove 412. The plate 41 is positioned by the steel ball. The cover plate 3 remains in the covered state. The second insertion part 552 is located in the limiting section of the fourth groove 523. The groove wall of the limiting section abuts against the second insertion part 552. The block 52 is blocked by the second insertion part 552. The second elastic element 53 is in a stretched energy storage state. The light-absorbing area 521 is close to the opening of the seedling hole 2. The baffle 524 blocks the connection between the third hole 63 and the third groove 51. The second rod 62 extends into the side area of ​​the seedling hole 2 near the opening. During the germination stage, combined with Figures 1 to 4 as well as Figure 8 Cover plate 3 covers the opening of seedling hole 2, reducing the rate of water loss in seedling hole 2. Light absorption area 521 absorbs light and heat, and the potting soil near seedling hole 2 gains heat. Baffle 524 seals the connection between third hole 63 and third trough 51, reducing air exchange between seedling hole 2 and outside of seedling tray 1. Second rod 62 remains in the side area of ​​seedling hole 2 near the opening, and second rod 62 does not produce soil-pulling action. Triggering phase, combined Figures 4 to 7 When the seed sprouts, the seedling supports the cover plate 3. After being supported, the cover plate 3 causes the plate body 41 to swing around the seat body 42. When the plate body 41 swings, the groove wall of the second groove 412 squeezes the steel ball of the first elastic element 421. The steel ball compresses the spring and retracts into the seat body 42. The steel ball exits the second groove 412, the plate body 41 is released from its position, and the cover plate 3 can continue to open away from the opening of the seedling hole 2. During the tripping phase, combined with Figures 4 to 9 The plate 41 is released from its positioning and continues to swing. The first groove 411 moves with the plate 41. The groove wall of the first groove 411 pushes against the first insertion part 551. After being pushed, the first insertion part 551 drives the first rod 55 to move along the first hole 54. When the first rod 55 moves, the shaft key slides in the keyway on the inner wall of the first hole 54. The shaft key restricts the rotation of the first rod 55, and the first rod 55 continues to move along the first hole 54. During the release phase, combined with Figures 4 to 9The first rod 55 drives the second insertion part 552 to move. The second insertion part 552 moves along the limiting section of the fourth groove 523 to the entrance of the driving section. The second insertion part 552 leaves the blocking position of the limiting section on the block 52, and the block 52 is no longer restricted. The elastic force of the second elastic member 53 pulls the block 52 to move along the third groove 51. When the block 52 moves in the third groove 51, the groove wall of the third groove 51 restricts the block 52 from tilting. During the light-changing stage, combined with Figure 3 and Figure 4 After block 52 moves, light-absorbing area 521 moves away from the area near the opening of seedling hole 2, and reflective area 522 moves to the area near the opening of seedling hole 2. The area near the opening of seedling hole 2 changes from heat-absorbing state to reflective state. After cover plate 3 is opened, reflective area 522 reduces the continued heat absorption near seedling hole 2. During the open-lid holding phase, combined with Figures 4 to 9 As block 52 continues to move, the driving section of fourth groove 523 contacts second insertion part 552. As the driving section gradually moves away from the inside of seedling tray 1 along the moving path of block 52, the groove wall of the driving section pushes against second insertion part 552 during the movement of block 52. Second insertion part 552 drives first rod 55 to continue moving. First rod 55 drives first insertion part 551 to continue moving. First insertion part 551 pushes against the groove wall of first groove 411. After being pushed by first insertion part 551, plate 41 continues to swing around seat 42. Cover 3 continues to open with plate 41. After second insertion part 552 enters the holding section of fourth groove 523, the holding section accommodates second insertion part 552. First rod 55 remains in the raised position. Plate 41 and cover 3 remain in the open state. During the soil removal stage, combined with Figures 4 to 9 When block 52 moves, it drives second rod 62 to move along second hole 61. One end of second rod 62 extends into seedling hole 2 and moves in the side area of ​​seedling hole 2 near the opening. The blunt end of second rod 62 agitates the surface culture soil. After the surface culture soil is agitated, a loose area is formed. This loose area increases the gaps in the culture soil near the opening of seedling hole 2, allowing air to enter the interior of the surface culture soil.

[0037] During the ventilation phase, combined with Figures 8 to 11 When block 52 moves, it also drives baffle 524 to move. Baffle 524 leaves the connection between third hole 63 and third groove 51. The connection is opened, and the area of ​​seedling hole 2 away from the open is connected to the outside of seedling tray 1 through third hole 63. Moisture in seedling hole 2 can be discharged through third hole 63.

[0038] In summary, when the cover plate 3 is supported by the seedling, it causes the plate body 41 to swing. The plate body 41 moves the first rod body 55 through the first groove 411 and the first insertion part 551. The first rod body 55 releases the obstruction of the block body 52 through the second insertion part 552. The second elastic element 53 pulls the block body 52 to move. The block body 52 causes the light-absorbing area 521 and the light-reflecting area 522 to switch positions. The block body 52 continues to push the first rod body 55 through the fourth groove 523, keeping the cover plate 3 open. The block body 52 also simultaneously drives the second rod body 62 to move the surface culture soil and causes the baffle 524 to open the third hole 63. Through the above coordination, the seedling hole 2 switches from the germination and heat preservation state to the seedling ventilation state.
