Description

Technical Field

[0001] The present application relates to the technical field of seed cultivation, and in particular to a device for cultivating and germinating forest seeds. Background Art

[0002] Seeds are reproductive bodies unique to gymnosperms and angiosperms. They are formed by ovules through pollination and fertilization. In agricultural production, in order to improve the germination rate and seedling rate of seeds, the seeds are germinated before planting, and then transplanted and planted after the seeds germinate and form seedlings.

[0003] As seed cultivation continues to develop, researchers in related fields have also made extensive optimizations to seed cultivation and germination devices. To achieve better accuracy comparisons, Chinese patent application number CN115104464A discloses a seed cultivation device comprising an incubator, wherein the inner bottom wall of the incubator is provided with a forward and reverse motor, the forward and reverse motor is provided with one end of a rotating shaft, the other end of the rotating shaft contacts the inner top wall of the incubator, the rotating shaft is provided with multiple layers of stirring blades, the inner side wall of the incubator is provided with a plurality of cultivation trays along the height direction, all of which are movably mounted on the rotating shaft, the cultivation trays and stirring blades are staggered, and the inner side wall of the incubator is provided with a heating plate. The cooperation of the heating plate and stirring blades evenly distributes the generated heat within the incubator, so that the seeds are heated evenly.

[0004] However, the above-mentioned process for seed cultivation and germination device still has some shortcomings in use:

[0005] 1. In terms of watering, although the above-mentioned prior art is provided with components such as a connecting pipe, a high-pressure pump and a liquid storage tank, the liquid in the liquid storage tank can be introduced into the rotating shaft and the stirring blade through the connecting pipe, and then watered to the seeds in the cultivation tray through the circulation port. However, because the water flows downward, the circulation port on the lowest stirring blade sprays water or nutrient solution first, and the circulation port on the uppermost stirring blade sprays water or nutrient solution last. Moreover, when pouring is finished, the uppermost cultivation tray also finishes pouring first. Therefore, the pouring amount of water or nutrient solution poured into each layer of the cultivation tray is different.

[0006] 2. The above-mentioned prior art uses the rotation of the stirring blade to evenly spray the water or nutrient solution on the cultivation tray. However, the rotation of the stirring blade causes the water or nutrient solution sprayed from the flow port to undergo centrifugal motion, thereby causing more water or nutrient solution to be sprayed on the outside of the cultivation tray. In other words, the water or nutrient solution poured on the cultivation tray is not evenly distributed.

[0007] Based on this, under the above-mentioned viewpoints, there is still a lot of room for improvement in the existing seed cultivation and germination devices. Summary of the Invention

DETAILED DESCRIPTION

[0042] The following is combined with Figures 1 to 12 This application is described in further detail.

[0043] The embodiment of the present application discloses a forest seed cultivation and germination device, which can realize the germination and cultivation of forest seeds, and can ensure that the forest seeds on the cultivation tray 3 can be evenly sprayed during the cultivation process, so that water or nutrient solution is evenly distributed; at the same time, the cultivation tray 3 of the present invention can separate and filter out excess water or nutrient solution to prevent affecting the germination and growth of forest seeds.

[0044] Example 1:

[0045] See Figure 1 and Figure 2, a forest seed cultivation and germination device includes a protection box 1, a take-out port 11 is opened on one side of the protection box 1, a cultivation box 2 is arranged in the protection box 1, the take-out port 11 passes through the cultivation box 2, and a plurality of cultivation trays 3 for placing forest seeds are arranged in sequence along the longitudinal direction in the cultivation box 2. By arranging multiple cultivation trays 3, the cultivation box 2 can cultivate and germinate more forest seeds at a time; a mist spray device 4 is arranged above each cultivation tray 3 to evenly spray the forest seeds on the cultivation tray 3; water replenishing devices 5 installed on the side walls of the cultivation box 2 are provided on both sides of the mist spray device 4 to timely replenish water or nutrient solution in the mist spray device 4; a driving device 6 cooperating with the mist spray device 4 is provided at the bottom of the cultivation box 2 to drive the mist spray device 4 to evenly spray the forest seeds on the cultivation tray 3.

[0046] In the specific implementation process, the liquidambar seeds are evenly planted on the cultivation tray and then sent to the cultivation box 2 for cultivation and germination. During the cultivation and germination process, the liquidambar seeds need to be sprayed with water or nutrient solution. Specifically, the driving device 6 drives the mist spray device 4 to move back and forth above the cultivation tray 3 so as to evenly spray the liquidambar seeds. At the same time, the water replenishing device 5 will replenish water or nutrient solution into the mist spray device 4 in time to achieve the purpose of reciprocating spraying of the mist spray device 4.

[0047] In order to facilitate those skilled in the art to further understand the present invention, the cultivation box 2, the mist spray device 4, the water replenishing device 5 and the driving device 6 are described in detail below.

[0048] See Figure 3 The cultivation tray 3 includes a breeding tray 31 and a water collecting tray 32. The water collecting tray 32 is detachably mounted at the lower end of the breeding tray 31, and a gap is left between the water collecting tray 32 and the breeding tray 31. A number of drainage holes 33 are evenly arranged on the breeding tray 31, and breeding trays with different drainage apertures can be selected according to the size of the seeds. After the forest seeds are planted on the breeding tray 31, when the mist spraying device 4 sprays them, excess water or nutrient solution will seep into the water collecting tray 32 through the drainage holes 33 at the bottom of the breeding tray 31, thereby avoiding excess water or nutrient solution remaining in the breeding tray 31 and affecting the normal cultivation and germination of the forest seeds.

[0049] In addition, the breeding tray 31 and the water collecting tray 32 are previously installed in a detachable manner, so that the water collecting tray 32 can be removed later to clean the soil in the water collecting tray 32 and the excess water or nutrient solution that seeps out of the breeding tray 31 through the drainage holes 33.

[0050] See Figure 3 The cultivation box 2 and the side walls on both sides of the access port 11 are provided with support platforms 21 for placing the water collecting tray 32. The water collecting tray 32 is placed between the two support platforms 21 to ensure that the forest seeds on the breeding tray 31 are successfully cultivated and germinated.

[0051] See Figure 3 and Figure 4 The mist spray device 4 includes a liquid supply pipe 41, which is horizontally arranged above the breeding tray 31 and perpendicular to the length direction of the support platform 21. Support blocks 42 are provided at both ends of the liquid supply pipe 41. Sliding holes 43 for the support blocks 42 to slide are provided on both side walls of the incubator 2. The support blocks 42 at both ends of the liquid supply pipe 41 slide in the sliding holes 43 to realize the movement of the liquid supply pipe 41, so that the liquid supply pipe 41 can evenly spray the forest seeds on the breeding tray 31; an I-shaped slide rail 44 is provided in the sliding hole 43 along its length direction, and the support block 42 is connected to the I-shaped slide rail 44. The sliding blocks 45 cooperate with the I-shaped slide rail 44, and the support block 42 slides on the I-shaped slide rail 44 through the sliding block 45 to realize the reciprocating motion of the liquid supply pipe 41; the end of the support block 42 away from the liquid supply pipe 41 is connected to the driving device 6, and the driving device 6 provides power for the reciprocating movement of the liquid supply pipe 41; the liquid supply pipe 41 faces one side of the breeding tray 31 and is connected to a plurality of nozzles 46 at equal intervals along its length direction. The nozzles 46 face the breeding tray 31 and are installed on the liquid supply pipe 41 to spray the water or nutrient solution in the liquid supply pipe 41 evenly to the breeding tray 31 through the nozzles 46.

[0052] During the specific implementation process, driven by the driving device 6, the support blocks 42 at both ends of the liquid supply pipe 41 slide back and forth on the I-shaped slide rail 44 through the sliding block 45, so that the water or nutrient solution in the liquid supply pipe 41 is evenly sprayed onto the breeding tray 31 through the nozzle 46.

[0053] Replay Figure 2 The liquid supply pipe 41 moves back and forth to spray the forest seeds on the breeding tray 31, which needs to be powered by the driving device 6 to ensure that the liquid supply pipe 41 can move back and forth smoothly on the I-shaped slide rail 44. Specifically, the driving device 6 includes a vertically distributed linkage bar 61 provided on the outer sides of both sides of the take-out and release port 11 of the incubator 2, and the support block 42 is connected to the linkage bar 61. The two ends of the linkage bar 61 are connected to a horizontally arranged transmission screw 62 that is threadedly engaged with it. The transmission screw 62 rotates axially and is connected to the linkage bar 61 through thread engagement, so that the linkage bar 61 drives the support block 42 to slide back and forth; the transmission screw 62 is distributed along the length direction of the sliding hole 43 and its two ends are rotatably mounted on the inner wall of the protection box 1. A first sprocket 63 is installed on the transmission screw 62, and the two first sprockets 63 on one side of the take-out and release port 11 are connected by a first chain 64. The cooperation of the first sprocket 63 and the first chain 64 can realize the synchronous and unidirectional rotation of the two transmission screws 62 on the same side of the take-out and release port 11.

[0054] A drive motor 65 is installed at the bottom of the incubator 2 through a motor seat, and two second sprockets 66 are installed on the output shaft of the drive motor 65. A third sprocket 67 is installed on the transmission screw 62 at the bottom of the incubator 2 and on one side of the second sprocket 66. The adjacent second sprockets 66 and third sprockets 67 are connected by a second chain 68.

[0055] During the specific implementation process, the drive motor 65 is started to make the two second sprockets 66 on the output shaft of the drive motor 65 rotate synchronously. At the same time, with the cooperation of the second chain 68 and the third sprocket 67, the transmission screws 62 on both sides of the pick-up and release port 11 rotate synchronously and in the same direction, thereby realizing that all the transmission screws 62 rotate synchronously and in the same direction, so as to synchronously drive the linkage bars 61 on both sides of the pick-up and release port 11 to move synchronously, and then realize the reciprocating movement of the liquid supply tube 41 through the support block 42.

[0056] See Figure 12 The figures show the differences in germination indexes of Liquidambar formosana seeds under different sowing methods. When the forest tree seeds were germinated at a temperature of 25°C / 15°C, the germination rate increased by 32.8%, the 7-day germination potential increased by 36.7%, the germination index increased by 2.07, and the normal seedling rate increased by 14.3% when the equipment of the present invention was used compared with the commonly used greenhouse substrate cultivation. Compared with germination in a culture dish in a climate box, the germination rate increased by 6.2%, the 7-day germination potential increased by 8.1%, the germination index decreased by 0.73, and the normal seedling rate increased by 9.2%.

[0057] Example 2:

[0058] Continue reading Figure 3 On the basis of Example 1, when the liquid supply pipe 41 sprays the forest seeds on the breeding tray 31, in order to ensure that there is enough water or nutrient solution in the liquid supply pipe 41 to replenish the liquid supply pipe 41 in time, the present invention realizes this function through a water replenishing device 5. Specifically, the water replenishing device 5 includes a water replenishing tank 51 installed on the side wall of the cultivation box 2, and one end of the water replenishing tank 51 is connected to a water supply branch pipe 52. A longitudinally extending water supply main pipe 53 is provided in the protection box 1 and located on the outside of the cultivation box 2, and the water supply branch pipe 52 is connected to the water supply main pipe 53; a water storage tank (not shown in the figure) is provided on the top of the protection box 1, and the water storage tank is connected to the water supply main pipe 53, that is, water or nutrient solution is poured into the water storage tank, and then flows into the water supply main pipe 53, and then enters the water replenishing tank 51 through the water supply branch pipe 52.

[0059] See Figures 3 to 5A water level control component 54 is provided on the side wall of the water replenishment tank 51 on the side of the water supply branch pipe 52 to prevent water or nutrient solution from overflowing from the water replenishment tank 51; and a water replenishment component 55 is provided at the bottom of the water replenishment tank 51, and a collection box 56 for collecting liquid flowing out of the water replenishment tank 51 through the water replenishment component 55 is provided on the support block 42. The support block 42 is a hollow shell structure and its two ends are respectively connected to the collection box 56 and the liquid supply pipe 41; the water or nutrient solution in the water replenishment tank 51 is replenished into the collection box 56 through the water replenishment component 55, and then enters the liquid supply pipe 41 through the support block 42 with a hollow shell structure.

[0060] See Figures 5 to 7 The water replenishment component 55 includes a water replenishment port 551 opened at the bottom of the water replenishment tank 51, and several water replenishment ports 551 are evenly spaced along the length direction of the water replenishment tank 51. A valve block 552 is slidingly arranged at the water replenishment port 551, and the valve block 552 is in sliding contact with the bottom of the water replenishment tank 51 through a sealing strip (not shown in the figure). Both sides of the valve block 552 are provided with limiting guide rails 553 that slide with it, and the limiting guide rails 553 are installed at the bottom of the water replenishment tank 51. The valve block 552 slides on the water replenishment port 551 through the limiting guide rails 553 to control the water or nutrient solution in the water replenishment tank 51 to flow downward through the water replenishment port 551 into the collection box 56.

[0061] A valve limit block 554 is provided at the bottom of the water supply tank 51 and on the side of the sliding direction of the valve block 552. The valve limit block 554 located on one side of the breeding tray 31 is located on the side of the valve block 552 away from the take-in and release port 11, and the valve limit block 554 located on the other side of the breeding tray 31 is located on the side of the valve block 552 toward the take-in and release port 11, and a limit spring 555 is connected between the valve block 552 and the valve limit block 554 to push the valve block 552 to move on the water supply port 551. The valve limit block 554 drives the valve block 552 to move in the direction away from the valve limit block 554 through the limit spring 555 to block the water supply port 551.

[0062] An opening and closing assembly 57 for opening the water supply port 551 is provided between the valve block 552 and the collection box 56. The opening and closing assembly 57 includes an elastic telescopic block 571. The fixed end of the elastic telescopic block 571 is installed at the bottom of the valve block 552. The elastic telescopic block 571 drives the valve block 552 to move synchronously; a guide port 572 is provided at the telescopic end of the elastic telescopic block 571, and a limiting inclined block 573 is provided at the outer bottom of the water supply tank 51 and on the side of the elastic telescopic block 571 facing the limit spring 555. The inclined surface 574 of the limiting inclined block 573 faces the direction of the elastic telescopic block 571, and the inclined surface 574 of the limiting inclined block 573 is distributed longitudinally and inclined toward the guide port 572.

[0063] During the specific implementation process, when the liquid supply pipe 41 moves along the direction of the I-shaped slide rail 44, it will drive the collection box 56 to move synchronously. When the collection box 56 moves to the position of the elastic telescopic block 571, it will push the elastic telescopic block 571 to move synchronously, so that the elastic telescopic block 571 can drive the valve block 552 to move synchronously. At this time, the limit spring 555 is in a compressed state, and the movement of the valve block 552 can open the water supply port 551, so that the water or nutrient solution in the water supply tank 51 enters the collection box 56 through the water supply port 551.

[0064] As the collection box 56 pushes the elastic telescopic block 571 to move, the guide port 572 of the elastic telescopic block 571 will interfere with the inclined surface 574 of the limiting inclined block 573 to drive the telescopic end of the elastic telescopic block 571 to move toward its fixed end until the telescopic end of the elastic telescopic block 571 is out of contact with the collection box 56. The telescopic end of the elastic telescopic block 571 is reset, and the limiting spring 555 in a compressed state at this time pushes the valve block 552 back to the initial position to close the water supply port 551 so that water or nutrient solution no longer flows out.

[0065] It should be noted that a gap is left between the end of the elastic telescopic block 571 away from the limiting inclined block 573 and the water supply port 551 to ensure that after the water supply port 551 is opened, the water or nutrient solution in the water supply tank 51 completely enters the collection box 56.

[0066] Continuing with the above steps, when the telescopic end of the elastic telescopic block 571 is reset, the telescopic block is now located in the collection box 56. As the collection box 56 continues to move, the elastic telescopic block 571 will conflict with the other side of the collection box 56, which will cause the collection box 56 to continue to push the elastic telescopic block 571 to move, and then the water replenishment port 551 continues to open, causing the water or nutrient solution in the water replenishment tank 51 to flow out of the collection box 56. Therefore, the present invention provides a through-hole 575 on both sides of the top of the collection box 56 along the length direction of the sliding hole 43. The collection box 56 is provided with a flip block 576 at the through-hole 575 on the side of the limit spring 555 facing the valve limit block 554. The flip block 576 is rotatably installed in the through-hole 575 on the side facing the bottom of the through-hole 575 by a torsion spring (not shown in the figure). The two side walls of the through-hole 575 are provided with a limit baffle 578 that limits the flip block 576 from rotating into the collection box 56, and the elastic telescopic block 571 slides through the gap between the two limit baffles 578.

[0067] During the specific implementation process, when the flip block 576 on the collection box 56 moves toward the elastic telescopic block 571, the telescopic end of the elastic telescopic block 571 collides with the flip block 576. Due to the restriction of the limit baffle 578, the flip block 576 will not rotate in the direction of the limit baffle 578, so that the collection box 56 drives the elastic telescopic block 571 to move synchronously through the flip block 576 to open the water supply port 551. When the elastic telescopic block 571 moves to the limit bevel block 573, the telescopic end of the elastic telescopic block 571 contracts. At this time, the valve block 552 blocks the water supply port 551 again; then when the collection box 56 continues to move, the telescopic end of the elastic telescopic block 571 will pass through the through-hole 575. At this time, the collection box 56 completes the fluid replenishment through the water supply port 551.

[0068] The above steps can complete the water replenishment when the liquid supply pipe 41 moves in one direction, but cannot achieve timely water replenishment when the liquid supply pipe 41 moves in the opposite direction. Therefore, the water replenishment components 55 provided in the water replenishment tanks 51 on both sides of the incubator 2 operate in opposite directions, that is, the water replenishment tank 51 on one side of the incubator 2 completes the water replenishment in the forward direction of the liquid supply pipe 41, and the water replenishment tank 51 on the other side of the incubator 2 completes the water replenishment in the return direction of the liquid supply pipe 41. Therefore, the valve limit block 554 on one side of the breeding tray 31 is located on the side of the valve block 552 away from the access port 11, and the valve limit block 554 on the other side of the breeding tray 31 is located on the side of the valve block 552 toward the access port 11, as shown in FIG. Figure 7 shown.

[0069] When the water replenishment component 55 on one side of the incubator 2 replenishes water to the liquid supply pipe 41, the water replenishment component 55 on the other side does not replenish water. Specifically, when the collection box 56 moves, the telescopic end of the elastic telescopic block 571 enters the collection box 56 through the through-hole 575 of the collection box 56. Then, the collection box 56 continues to move, which will cause the telescopic end of the elastic telescopic block 571 to contact the flip block 576. Since the flip block 576 is installed in the through-hole 575 by a torsion spring, the telescopic end of the elastic telescopic block 571 will push the flip block 576 to rotate, so that the elastic telescopic block 571 can be smoothly moved out of the collection box 56. At this time, the collection box 56 smoothly passes through the water replenishment port 551, and then the flip block 576 smoothly rotates and resets under the action of the torsion spring.

[0070] It should be noted that the elastic force of the limit spring 555 is greater than the torsional force of the torsion spring, so as to ensure that when the elastic telescopic block 571 pushes the flip block 576 to rotate, the valve block 552 does not move, thereby preventing the water or nutrient solution in the water replenishment tank 51 from overflowing through the water replenishment port 551.

[0071] See Figure 9In order to ensure that there is enough water or nutrient solution in the collection box 56 to be replenished in the liquid supply pipe 41 in time, the water replenishment tank 51 needs to provide enough water or nutrient solution to flow into the collection box 56 through the water replenishment port 551. However, if the opening of the water replenishment port 551 is too large, the water or nutrient solution in the collection box 56 will overflow. If the opening of the water replenishment port 551 is too small, the liquid supply pipe 41 cannot be replenished with enough water or nutrient solution in time. Therefore, the present invention is provided with an adjustment component 58 for controlling the movement of the limiting inclined block 573 at the bottom of the water replenishment tank 51. Specifically, the adjustment component 58 includes a regulating component 58 and a limiting component 58. The positioning bevel block 573 is connected to the sliding block 581 on one side of the water supply tank 51. The sliding block 581 is slidably set at the bottom of the water supply tank 51, and an adjusting screw 582 is distributed on one side of the incubator 2 and along the length direction of the water supply tank 51. Both ends of the adjusting screw 582 are rotatably installed on the inner wall of the protection box 1, and the end of the adjusting screw 582 facing the take-and-release port 11 passes through the protection box 1 and is equipped with a handle 583. A number of adjusting blocks 584 corresponding to the positioning bevel block 573 are threadedly connected to the adjusting screw 582, and the adjusting block 584 and the positioning bevel block 573 are connected by a connecting strip 585.

[0072] During the specific implementation process, when the handle 583 installed on the taking and releasing port 11 is rotated, the adjusting screw 582 will be driven to rotate, so that the adjusting block 584 moves along the axis direction of the adjusting screw 582, thereby driving the connecting bar 585 to move synchronously, and then the limiting bevel 573 slides along the axis direction of the adjusting screw 582 at the bottom of the water supply tank 51 through the sliding block 581, thereby changing the distance between the limiting bevel 573 and the elastic telescopic block 571, so as to change the opening size of the water supply port 551 to realize the flow rate of water or nutrient solution in the water supply tank 51 flowing out through the water supply port 551, and then the flow rate of water or nutrient solution flowing into the collection box 56 is also controlled to avoid excessive water or nutrient solution overflowing the collection box 56, or too little water or nutrient solution is not enough to replenish the liquid supply pipe 41 in time.

[0073] See Figure 7 and Figure 8In order to ensure that there is enough water or nutrient solution in the water supply tank 51 to be replenished in time into the collection box 56, the water supply branch pipe 52 needs to provide enough water or nutrient solution to flow into the water supply tank 51 through the water supply port 541. However, if the water supply port 541 is not restricted, the water or nutrient solution in the water supply tank 51 will overflow. If the water supply port 541 is restricted too much, the water or nutrient solution in the water supply port 541 cannot be replenished in time. Therefore, the present invention can prevent the water or nutrient solution in the water supply tank 51 from overflowing the water supply tank 51 through the water level control component 54. Specifically, the water level control component 54 includes a water supply port 541 opened on the side wall of the water supply tank 51 near the water supply branch pipe 52, and the water supply branch pipe 52 is connected to the water supply port 541, and a floating block 542 is provided on the inner wall of the water supply tank 51 at the water supply port 541 for sliding through a sealing gasket, and the water supply tank 51 is provided with floating guide rails 543 on both sides of the water supply port 541 for the floating block 542 to slide longitudinally, and a floating block 545 is provided between the tops of the two floating guide rails 543 to limit the sliding of the floating block 542.

[0074] In the specific implementation process, when the water or nutrient solution in the water supply branch pipe 52 flows into the water supply tank 51 through the water supply port 541, the floating block 542 will move up as the water level of the water or nutrient solution rises, until the floating block 542 slides upward along the floating guide rail 543 to the floating block 545. At this time, the water supply port 541 is just blocked by the floating block 542, so that the water or nutrient solution no longer flows into the water supply tank 51, thereby preventing the water or nutrients in the water supply tank 51 from overflowing; because the floating block 542 blocks the water or nutrient solution from flowing into the water supply tank 51, the floating block 542 stops the water or nutrient solution from flowing into the water supply tank 51. The floating block 542 moves out of the water supply port 541, so that the water or nutrient solution in the water supply branch pipe 52 flows into the water supply tank 51 through the water supply port 541 again. As the water or nutrient solution level in the water supply tank 51 rises again, the floating block 542 moves up and blocks the water supply port 541, and the above process is repeated, so that the water or nutrient solution in the water supply tank 51 is always kept within a certain range.

[0075] See Figure 10 and Figure 11In order to ensure that the excess water or nutrient solution on the breeding tray 31 can be discharged in time during the spraying process, the present invention sets a water collecting tray 32 at the lower end of the breeding tray 31 to collect the excess water or nutrient solution. However, the capacity of the water collecting tray 32 is limited and needs to be cleaned frequently. Therefore, the present invention sets a guiding slope 311 on the inner side wall of the breeding tray 31 along the length direction of the support platform 21, and a water filter hole 312 connected to the water collecting tray 32 is opened at the bottom of the guiding slope 311. The water or nutrient solution sprayed by the nozzle 46 on the inner wall of the cultivation box 2 flows into the water filter hole 312 through the guiding slope 311; the bottom of the water collecting tray 32 is provided with a water diversion slope 321 extending downward from the middle to both sides of the support platform 21; it can guide the water or nutrient solution in the water collecting tray 32 to both sides of the water collecting tray 32.

[0076] A confluence trough 211 is provided on the support platform 21, and a through confluence hole 322 is provided in the area of ​​the water collecting tray 32 located above the confluence trough 211. A confluence inlet 12 connected to the confluence trough 211 is provided on the inner wall of the protective box 1 away from the taking and releasing port 11, and a drainage hole 13 connected to the confluence inlet 12 is provided in the protective box 1 along the longitudinal direction; the water or nutrient solution in the confluence trough 211 flows into the drainage hole 13 through the confluence inlet 12.

[0077] A water collecting box 14 is slidingly provided at the bottom of the protection box 1 , and a drainage inclined pipe 15 is connected to the bottom of the drainage hole 13 , and one end of the drainage inclined pipe 15 away from the drainage hole 13 passes through the side wall of the protection box 1 and is located above the water collecting box 14 .

[0078] During the specific implementation process, the excess water or nutrient solution in the breeding tray 31 seeps into the water collecting tray 32 through the drainage hole 33 and the water filter hole 312, and the water or nutrient solution sprayed by the nozzle 46 on the inner wall of the cultivation box 2 flows downward to the guide slope 311, and then enters the water collecting tray 32 through the water filter hole 312; the water or nutrient solution collected in the water collecting tray 32 flows to the confluence hole 322 through the water diversion slope 321 and then converges into the confluence groove 211 on the support platform 21, and then enters the drainage hole 13 through the confluence inlet 12, and finally flows into the water collecting tank 14 through the drainage inclined pipe 15; after enough waste liquid is stored in the water collecting tank 14, the water collecting tank 14 is pumped out so that the waste liquid in the water collecting tank 14 can be cleaned.

[0079] The implementation principle of the present invention is:

[0080] (1): Plant the tree seeds in the breeding tray 31, then place the breeding tray 31 on the water collecting tray 32 and send them into the cultivation box 2 for breeding and germination.

[0081] (2): The germination of forest seeds requires a certain amount of moisture and humidity. Pour the prepared water or nutrient solution into the water tank, and then smoothly enter the water replenishment tank 51 under the circulation of the water supply main pipe 53 and the water supply branch pipe 52. Then, with the assistance of the water replenishment component 55, the water or nutrient solution in the water replenishment tank 51 smoothly enters the liquid supply pipe 41 so that it can be evenly sprayed onto the breeding tray 31 through the nozzle 46.

[0082] (3): In order to ensure that the nozzle 46 sprays evenly onto the breeding tray 31, the driving device 6 drives the liquid supply pipe 41 to slide back and forth along the I-shaped slide rail 44, so that the water or nutrient solution in the liquid supply pipe 41 can be evenly sprayed onto the forest seeds on the breeding tray 31 through the nozzle 46.

[0083] (4): During the spraying process of water or nutrient solution, the excess water or nutrient solution in the breeding tray 31 enters the water collecting tray 32 through the drainage hole 33, and then converges into the confluence trough 211 through the confluence hole 322, and finally enters the water collecting tank 14 through the drainage hole 13 and the drainage inclined tube 15, which is convenient for subsequent cleaning.

[0084] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
