The end of the conveying pipe 521 furthest from the mixing pipe 520 passes through the irrigation tank 1 and connects to the water tray 506. A second pump 522 is installed outside the mixing pipe 520. The output end of the second pump 522 is connected to the mixing pipe 520 via a narrow pipe. A conveying pipe 523 is installed on the mixing pipe 520. The end of the conveying pipe 523 furthest from the mixing pipe 520 is bolted to a feeding cylinder 524.

[0026] In specific application scenarios, the recycling module 5 is mainly applicable to the recycling stage of the recycling process. Specifically, the recycling module 5 utilizes the water storage tank 4, water inlet trough 503, guide pipe 507, collection well 515, and infiltration pipe 516 to promptly collect and store rainwater and saturated free water in the soil that seedlings cannot absorb in time. This greatly improves the efficiency of water resource recycling and storage. By reusing rainwater, it ensures that seedlings can still receive sufficient irrigation during dry seasons, ensuring that their growth is not affected. The round rod 511, threaded rod 512, mounting plate 2, absorbent sponge 502, and water tray 506 can control the amount of water irrigated to the seedlings at one time, thereby ensuring that the seedlings can... While ensuring sufficient water supply, the device also guarantees the aeration of the seedling roots in the soil, preventing root rot. The mixing pipe 520, conveying pipe 521, feeding cylinder 524, discharging box 525, rotating block 526, fertilizer injection connector 531, and distribution trough 527 allow for simultaneous irrigation and fertilization. The distribution trough 527 enables nursery workers to control the amount of fertilizer applied according to the seedling's growth stage, reducing workload and improving the precision of fertilization. The U-shaped elbow 519 prevents the fertilizer-mixed water in the mixing pipe 520 from flowing back into the water storage tank 4, thus preventing eutrophication and the growth of algae and other unnecessary impurities, ensuring water quality and minimizing adverse effects on seedling growth.

[0027] Reference Figure 7 In a preferred embodiment, the limiting and stabilizing module 6 includes a stabilizing ring 601 located outside the threaded rod 512. The bottom of the stabilizing ring 601 is slidably connected to the upper side of the fixing plate 510 on the same side, and a guide buckle 604 is slidably connected to the outside of the stabilizing ring 601. The bottom of the guide buckle 604 is bolted to the upper side of the stabilizing ring 601. A toothed ring 602 is provided outside the threaded rod 512. The bottom of the toothed ring 602 is rotatably connected to the upper side of the fixing plate 510 via a bearing. An arc-shaped rack 603 is bolted to the inner wall of the stabilizing ring 601. The arc-shaped rack 603 engages with the toothed ring 602. A second spring 605 is bolted to the side of the guide buckle 604 away from the threaded rod 512. The end of the second spring 605 away from the guide buckle 604 is bolted to the inner wall of the stabilizing ring 601.

[0028] Specifically, when adjusting the depth of the mounting plate 2 in the irrigation tank 1, the spring force of the second spring 605 is overcome to push the stabilizing ring 601, so that the arc-shaped rack 603 connected to the stabilizing ring 601 releases the lock on the toothed ring 602, thereby allowing the threaded rod 512 to rotate smoothly. After the adjustment is completed, the stabilizing ring 601 is released, the second spring 605 pushes the stabilizing ring 601 to reset, so that the arc-shaped rack 603 relocks the toothed ring 602, and the threaded rod 512 can no longer rotate.

[0029] In specific application scenarios, the limit stabilization module 6 is mainly used for the limit stabilization link in the limit stabilization process. That is, the limit stabilization module 6 uses the stabilizing ring 601, spring 605, toothed ring 602 and arc-shaped rack 603 to lock the rotation of the threaded rod 512, thereby avoiding the situation where the threaded rod 512 is subjected to force and self-rotation due to excessive load on the mounting plate 2. This ensures that the seedlings or seeds in the cultivation pot 3 can maintain the distance from the water tray 506 when irrigation is not required, thereby ensuring that the soil in the cultivation pot 3 will not be over-watered, causing root rot or seed decay and damage, and ensuring the stability of the device's breeding.

[0030] A method for cultivating forestry seedlings, using a forestry seedling cultivation device as described above, includes the following steps:

[0031] Step 1: Place the plants or seeds that need to be cultivated into the cultivation pot 3, and then place the cultivation pot 3 into the slots on the mounting plate 2 in sequence.

[0032] Step 2: During the rainy season, the recycling module 5 can collect rainwater flowing on the mounting plate 2 and accumulating in the soil that cannot be absorbed by the seedlings in time, and store it in the water storage tank 4.

[0033] Step 3: During the dry season, lower the mounting plate 2 in irrigation tank 1. Use the recycling module 5 to extract the remaining rainwater and mix it with fertilizer to irrigate the seedlings. During and after irrigation, the depth of the mounting plate 2 in irrigation tank 1 is controlled by the limiting and stabilizing module 6. (During the rainy season, rainwater falling on the mounting plate 2 will be guided by the tilted mounting plate 2 into the water inlet trough 503, filtered by the filter plate 504, and then flow into irrigation tank 1. It then flows into the water storage tank 4 through the guide pipe 507. The water storage tank 4 is located below irrigation tank 1, which is located on the ground surface. The water storage tank 4 is located underground. The collection well 515, located around irrigation tank 1, is located in the soil of the nursery. During the rainy season, the water is collected through the infiltration pipe.) The siphon effect generated by pump 516 draws free water from the soil into the collection well 515 for storage. Pump 517 is activated, drawing water filtered through ceramic filter head 514 into the storage tank 4 via water pipe 513. When irrigation is needed for the seedlings in the cultivation pot 3, the threaded rod 512 is rotated, causing the connecting bracket 509 connected to the mounting plate 2 to descend, allowing the mounting plate 2 to slowly sink into the irrigation tank 1. Pump 522 is activated, pumping water from the storage tank 4 into the mixing pipe 520 via return pipe 518 and U-bend 519, and finally into the water tray 506 via delivery pipe 521, where a certain amount of water is stored. Afterwards, turn off pump 2 522. At this time, the water-absorbing sponge 502 at the bottom of the cultivation pot 3 on the lowered mounting plate 2 will contact the bottom inner wall of the water tray 506, thereby absorbing the water in the water tray 506 and finally transferring the water to the soil in the cultivation pot 3. When it is necessary to fertilize the seedlings, fill the discharge box 525 with fertilizer in advance, turn the rotating handle 528 to align the distributing groove 527 on the rotating block 526 with the corrugated pipe 534. Under the elastic force of spring 1 533, the fertilizer injection connector 531 slides down and connects with the distributing groove 527 on the same side, so that the fertilizer in the discharge box 525 is injected into the distributing groove 527. After the distributing groove 527 is full, continue to turn the rotating handle 528. 8. Press the edge of the dispensing trough 527 against the outside of the fertilizer injection connector 531, causing the fertilizer injection connector 531 to slide upward against the elastic force of the spring 533 and separate from the fertilizer-filled dispensing trough 527. At this time, the bottom of the fertilizer injection connector 531 will be completely in contact with the upper side of the rotating block 526. As the rotating handle 528 continues to rotate, the fertilizer injection connector 531 will fill the next empty dispensing trough 527. After the dispensing trough 527 coincides with the feeding hole 535, the fertilizer in the dispensing trough 527 will be transported to the mixing pipe 520 through the conveying pipe 523. When the pump 522 transports the water in the water storage tank 4 to the water tray 506, the fertilizer will mix with the water in the mixing pipe 520.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
