Description

Technical Field

[0001] This invention relates to the field of cutting propagation technology, and more specifically, to a device and method for propagating young shoots by cuttings. Background Technology

[0002] Aralia elata, also known as spiny aralia, is a perennial deciduous shrub or small tree. It contains protein, fat, carbohydrates, minerals, and vitamins. With its delicious, sweet, tender, and mellow flavor, and rich wild taste, Aralia elata is a famous wild vegetable, hailed as the "King of Wild Vegetables." Furthermore, it has high medicinal value; both the bark and roots can be used medicinally. The total saponin content in the root bark is about three times that of ginseng root. In addition, its roots, stems, leaves, flowers, and fruits also contain flavonoids, lignin, alkaloids, polysaccharides, volatile oils, and tannins.

[0003] Cutting propagation is an important method of asexual reproduction, offering advantages such as maintaining the superior traits of the parent plant, short propagation cycle, and low cost. It is widely used in the propagation of seedlings for forest trees, fruit trees, and specialty vegetables. Currently, common methods of propagating *Aralia elata* (thorn shoots) through cuttings mainly include soil cultivation and hydroponics. Soil cultivation involves inserting cuttings of tender shoots into soil or substrate. While soil cultivation provides stable physical support for the cuttings and results in a high transplant survival rate, the moisture level of the soil or substrate is difficult to judge directly. Water accumulation can easily lead to oxygen deficiency and rotting at the base of the cuttings. Furthermore, the supply of water and nutrients is difficult to guarantee and relies on manual experience, resulting in a low germination rate for soil cultivation.

[0004] Hydroponics involves immersing the base of a cutting of tender shoots directly into water or nutrient solution. While hydroponics provides ample water and nutrients and makes the roots visible, the dissolved oxygen in the water is limited, which can easily lead to root hypoxia. Furthermore, the loose structure of aquatic roots and their poor adaptability result in a low survival rate when transplanted to a solid substrate.

[0005] Therefore, how to improve the germination rate and transplant survival rate of Aralia elata cuttings is an urgent problem to be solved in this technical field. Summary of the Invention

[0021] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this invention, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] Example 1

[0023] like Figures 1-2 As shown, this embodiment provides a device for propagating *Aralia elata* buds by cuttings, comprising: A constant temperature chamber 1 is mounted on a support 2. A transparent cover 3 is detachably connected to the constant temperature chamber 1. The transparent cover 3 has multiple ventilation openings 31. Water level regulating mechanism 4 is installed inside the support 2. Water level regulating mechanism 4 is connected to constant temperature box 1. Water level regulating mechanism 4 is used to inject water or nutrient solution into the lower part of constant temperature box 1 and gradually adjust the water level of water or nutrient solution. The connecting frame 5 is set in the upper part of the constant temperature box 1. The connecting frame 5 has multiple docking interfaces 51. A soil fixing mechanism 6 is detachably connected to the docking interface 51. The soil fixing mechanism 6 is filled with soil medium. After the cuttings of the thorny shoots pass through the soil fixing mechanism 6, they enter the lower part of the constant temperature box 1. The soil medium promotes the growth of soil roots of the cuttings of the thorny shoots, while water or nutrient solution promotes the growth of aquatic roots of the cuttings of the thorny shoots. The dispatching mechanism 7 has its output end set on the connecting frame 5, and its input end is set through the constant temperature box 1. The dispatching mechanism 7 is used to transport water or nutrient solution in the constant temperature box 1 into the soil medium. The controller is connected to the water level regulating mechanism 4 and the dispatching mechanism 7.

[0024] Understandably, when propagating *Aralia elata* buds through cuttings, the bud branches are pruned into cuttings, which are then disinfected and treated to promote root growth. Multiple soil-fixing mechanisms 6 are then connected to the interface 51. The cuttings are inserted through the soil-fixing mechanisms 6, with their bottoms entering the lower part of the constant temperature chamber 1, where soil media is filled. After all the soil-fixing mechanisms 6 are filled with soil media, a transparent cover 3 is connected to the constant temperature chamber 1. The transparent cover 3, in conjunction with the constant temperature chamber 1, ensures a suitable seedling temperature, provides light protection, and the ventilation opening 31 ensures ventilation. Water is then injected into the water level regulating mechanism 4, which in turn injects water into the constant temperature chamber 1. During the root germination period of 1-14 days, the water level adjustment mechanism 4 is set by the controller to not gradually adjust the water level, and the water is changed every 1-2 days to ensure that the part of the cutting that enters the lower part of the constant temperature box 1 can successfully germinate aquatic roots. The scheduling mechanism 7 is activated for 10-15 minutes every 4-6 hours to transfer water from the constant temperature box 1 into the soil medium to maintain the humidity of the soil medium. Excess water in the soil medium flows back into the constant temperature box 1, thereby ensuring that the part of the cutting that is in the soil medium can successfully germinate terrestrial roots. During the initial rooting period of 15-25 days, the water in the constant temperature box 1 is replaced with nutrient solution through the water level regulating mechanism 4. The controller sets the water level regulating mechanism 4 to gradually adjust the water level, simulating the process of water loss in the natural environment. This synchronously regulates the humidity environment for both aquatic and terrestrial roots, training their environmental adaptability to improve the survival rate after transplanting. Once the water level reaches its minimum, the water level regulating mechanism 4 immediately recirculates the nutrient solution back into the constant temperature box 1. Inside, a gradual adjustment is made again, and the nutrient solution is changed every 3-5 days to ensure the nutrient supply during the initial rooting period. The scheduling mechanism 7 is activated every 4-6 hours for 10-15 minutes to transfer the nutrient solution in the constant temperature box 1 into the soil medium, increasing the humidity and fertility of the soil medium. Excess water in the soil medium flows back into the constant temperature box 1. The nutrient solution in the lower part of the constant temperature box 1 forms a hydroponic layer, and the soil medium in the upper part of the constant temperature box 1 forms a soil culture layer, which promotes the growth of aquatic roots and soil roots respectively, thereby improving the germination rate. During the 26-40 day root establishment period, the water level regulation mechanism 4 gradually adjusts the water level, lowering it to its lowest point. After an interval of 4-6 hours, the water level regulation mechanism 4 recirculates the nutrient solution back into the constant temperature box 1. During this interval, there is no nutrient solution in the lower part of the constant temperature box 1. The aquatic roots and terrestrial roots consume the water and nutrients absorbed by the aquatic roots and then absorb water and nutrients from the soil medium. This trains the aquatic and terrestrial roots to absorb water and nutrients and to adapt to the environment. The nutrient solution is recirculated back into the constant temperature box 1, and the gradual adjustment is performed again. Through the nutrient solution recirculation, the water and nutrients of the aquatic roots are replenished, preventing them from withering. The nutrient solution is replaced every 5-7 days. The dispatching mechanism 7 is activated for 10-15 minutes every 8-12 hours to transport the nutrient solution in the constant temperature box 1 into the soil medium, replenishing the humidity and fertility of the soil medium and providing conditions for the growth of both aquatic and terrestrial roots. During the 41-60 day transplanting period, the nutrient solution in the constant temperature box 1 is replaced with water through the water level regulating mechanism 4. The water level regulating mechanism 4 gradually adjusts the water level, lowering it to the lowest level. After 6-8 hours, the water level regulating mechanism 4 recirculates the water back into the constant temperature box 1, and the gradual adjustment is repeated. The water in the constant temperature box 1 is replaced every 5-7 days, and the scheduling mechanism 7 stops operating. This method of replenishing water to the aquatic roots at regular intervals provides a basic growth environment for the seedlings of Aralia elata, thereby further improving the environmental adaptability of the seedlings after transplanting. During the transplanting period, the seedlings of Aralia elata are transplanted. When transplanting, the soil fixing mechanism 6 is removed from the interface 51, and the soil clod formed with the soil medium is removed from the soil fixing mechanism 6 along with the seedling. The soil clod is transplanted together with the seedling, further improving the survival rate of the seedlings after transplanting.

[0025] In this technical solution, a hydroponic layer is formed by injecting water or nutrient solution into the lower part of the constant temperature box 1, and a soil culture layer is formed by setting soil medium in the upper part of the constant temperature box 1. This promotes the growth of the cuttings of Aralia elata into aquatic roots and terrestrial roots. The water level is gradually adjusted by the water level adjustment mechanism 4 to simulate the process of water loss in the natural environment, and the humidity environment of the aquatic roots and terrestrial roots is adjusted synchronously to improve the survival rate of transplanting. The water or nutrient solution in the constant temperature box 1 is transported into the soil medium by the dispatching mechanism 7, which increases the oxygen content in the soil medium, water or nutrient solution, and replenishes the water and fertilizer in the soil medium, thereby improving the germination rate and transplant survival rate of Aralia elata cuttings.

[0026] It should be noted that a screen is installed inside the ventilation opening 31 to prevent pests.

[0027] Soil media include mixed soils consisting mainly of loam, sand, humus, and organic fertilizer.

[0028] like Figure 3 As shown, the water level regulating mechanism 4 includes: The liquid storage tank 41 is installed inside the bracket 2. The liquid storage tank 41 is connected to the input end of the water pump 42. The output end of the water pump 42 is connected to the lower part of the constant temperature box 1 through the first pipe 43. The three-way pipe 44 has a first section 441 connected to the liquid storage tank 41, and a second section 442 connected to the water storage tank or water storage pool. A first solenoid valve 443 is connected to the first section 441, and a second solenoid valve 444 is connected to the second section 442. The regulating component 45 is installed inside the constant temperature chamber 1. The regulating component 45 is connected to the third pipe section 445 of the three-way pipe 44. The regulating component 45 is used to gradually adjust the water level of the water or nutrient solution in the constant temperature chamber 1.

[0029] Understandably, when water or nutrient solution is injected into the lower part of the constant temperature chamber 1, the water or nutrient solution is injected into the storage tank 41. After the water pump 42 is started for a certain period of time by the controller, the water pump 42 injects a metered amount of water or nutrient solution into the lower part of the constant temperature chamber 1. When the water level in the lower part of the constant temperature chamber 1 is gradually adjusted, the first solenoid valve 443 is opened and the second solenoid valve 444 is closed. The controller controls the adjustment component 45 to perform gradual adjustment, gradually adjusting the water level in the lower part of the constant temperature chamber 1 from high to low. During the gradual adjustment process of the adjustment component 45, the water or nutrient solution in the lower part of the constant temperature chamber 1 enters the third section 445 of the three-way pipe 44 through the adjustment component 45, and then... The water or nutrient solution enters the storage tank 41 through the first section 441 of the three-way pipe 44 until the water or nutrient solution in the lower part of the constant temperature box 1 drops to the minimum water level. After the water pump 42 is restarted, the water or nutrient solution is quantitatively injected into the lower part of the constant temperature box 1, and this cycle is repeated. When the water or nutrient solution is replaced, the first solenoid valve 443 is closed and the second solenoid valve 444 is opened. When the regulating component 45 is gradually adjusted, the waste liquid enters the third section 445 of the three-way pipe 44 through the regulating component 45, and then enters the water storage tank or water storage tank through the second section 442 of the three-way pipe 44 for collection. After the waste liquid in the storage tank 41 is discharged, new water or nutrient solution is injected, and the water pump 42 is restarted.

[0030] like Figure 4 As shown, the adjustment component 45 includes: The sealing shell 451 is connected to the constant temperature box 1. The bottom of the sealing shell 451 is provided with a storage groove 452. The middle position of the storage groove 452 is connected to the third pipe section 445. The telescopic tube 453 has its bottom end sealed to the storage groove 452. After the telescopic tube 453 is retracted, it is located in the storage groove 452. The top end of the telescopic tube 453 is connected to an adjusting ring 454. Multiple smooth rods 455 are connected inside the sealing shell 451. The adjusting ring 454 is slidably connected to the smooth rods 455. An adjusting rod 456 is mounted inside the adjusting ring 454. The electric actuator 457 is connected through the sealing shell 451, and the electric actuator 457 is connected to the adjusting rod 456 in a transmission manner.

[0031] Understandably, when gradually adjusting the water level in the lower part of the constant temperature chamber 1, the controller controls the electric actuator 457 to extend in multiple segments, with each segment extending at a set time interval. When the electric actuator 457 extends, the adjusting rod 456 drives the adjusting ring 454 to slide downwards along the smooth rod 455. The adjusting ring 454 compresses the telescopic tube 453 and retracts it into the receiving tank 452. The sealing shell 451 is connected to the constant temperature chamber 1, and the water level in the sealing shell 451 is consistent with the water level in the constant temperature chamber 1. After the telescopic tube 453 retracts, the water or nutrient solution in the constant temperature chamber 1 enters the third pipe section 445 through the telescopic tube 453. The liquid enters the storage tank 41 through the first pipe section 441 or the water storage tank or reservoir through the second pipe section 442. After the electric actuator 457 is fully extended, the telescopic tube 453 retracts into the receiving trough 452, and the water or nutrient solution in the constant temperature box 1 is completely discharged. At this time, it is the lowest water level. Then, the controller controls the electric actuator 457 to retract back to its original position. The electric actuator 457 drives the adjusting ring 454 to slide upward and reset through the adjusting rod 456. The telescopic tube 453 unfolds and resets. When the water pump 42 is restarted, water or nutrient solution is injected into the constant temperature box 1, thereby realizing the gradual adjustment of the water level of the water or nutrient solution in the constant temperature box 1.

[0032] like Figure 5 As shown, the storage tank 41 is divided into a temporary storage chamber 412 and an injection chamber 413 by a partition 411. The first pipe section 441 is connected to the temporary storage chamber 412. The injection chamber 413 is provided with an injection port 414. The input end of the water pump 42 is connected to a three-way connector 421. The three-way connector 421 is connected to a second pipe 422 and a third pipe 423 respectively. The second pipe 422 is connected to the injection chamber 413, and the third pipe 423 is connected to the temporary storage chamber 412. A third solenoid valve 424 is connected to the second pipe 422, and a fourth solenoid valve 425 is connected to the third pipe 423. A water quality detection sensor is provided in the lower part of the constant temperature box 1.

[0033] Understandably, when water or nutrient solution is injected into the lower part of the constant temperature chamber 1, the water or nutrient solution is injected into the injection chamber 413. The controller controls the third solenoid valve 424 to open and the fourth solenoid valve 425 to close. Subsequently, the water pump 42 is started for a certain period of time, and the water pump 42 injects a quantitative amount of water or nutrient solution from the injection chamber 413 into the lower part of the constant temperature chamber 1. When the regulating component 45 gradually regulates the water or nutrient solution in the constant temperature chamber 1, the water or nutrient solution discharged from the first pipe section 441 enters the temporary storage chamber 412 for storage. When it is injected into the constant temperature chamber 1 again, the controller controls the third solenoid valve 424 to close and the fourth solenoid valve 425 to open. The water pump 42 then delivers the water or nutrient solution from the temporary storage chamber 412 into the constant temperature chamber 1, thereby realizing the regulation of water or nutrient solution. The system allows for the recycling of water and nutrient solution. A water quality sensor monitors the water or nutrient solution in real time and feeds the information back to the controller. When the monitoring data does not meet the set seedling standard threshold, the controller controls the regulating component 45 to adjust the water level to the lowest setting and controls the first solenoid valve 443 to close and the second solenoid valve 444 to open. Waste liquid in the constant temperature chamber 1 enters the third pipe section 445 and then flows through the second pipe section 442 into the water storage tank or reservoir. Subsequently, the regulating component 45 resets, and the controller controls the third solenoid valve 424 to open and the fourth solenoid valve 425 to close. After the water pump 42 starts for a certain period, it injects a measured amount of water or nutrient solution from the injection chamber 413 into the lower part of the constant temperature chamber 1, thus completing the replacement of the water or nutrient solution and ensuring its full utilization.

[0034] like Figures 6-8 As shown, the soil stabilization mechanism 6 includes: The first U-shaped frame 61 has a first U-shaped plate 62 connected to its top end, a first U-shaped mesh plate 63 connected to its bottom end, and a first partition net 64 connected inside the first U-shaped frame 61. The second U-shaped frame 65 has a second U-shaped plate 66 connected to its top end. The two ends of the second U-shaped plate 66 are respectively provided with sliding grooves 67. The first U-shaped plate 62 is slidably connected in the sliding grooves 67. The two sides of the second U-shaped plate 66 are respectively provided with clamping plates 68, and the clamping plates 68 are provided with handles 69. The bottom end of the second U-shaped frame 65 is connected with a second U-shaped mesh plate 610. The bottom end of the second U-shaped mesh plate 610 is connected with a U-shaped positioning strip 611. The second U-shaped frame 65 is connected with a second partition net 612. Multiple long bolts 613 are installed through the first U-shaped plate 62, the slide groove 67, and the first U-shaped mesh plate 63. The long bolts 613 are threadedly connected to the U-shaped positioning strip 611.

[0035] Understandably, when propagating *Aralia elata* buds by cuttings, the first U-shaped plate 62 is slidably connected within the groove 67. The first U-shaped frame 61, the second U-shaped frame 65, together with the first partition net 64, the second partition net 612, the first U-shaped mesh plate 63, and the second U-shaped mesh plate 610, form a soil-filled dish. Subsequently, multiple long bolts 613 are threaded through the first U-shaped plate 62, the groove 67, and the first U-shaped mesh plate 63, and then threadedly connected to the U-shaped positioning strip 611. The connection between the first U-shaped frame 61 and the second U-shaped frame 65 is fixed by the limiting effect of the long bolts. Then, the soil-filled dish is inserted into the joint. Inside the opening 51, the installation position of the soil-filled dish is restricted by the clamps 68 integrally set on both sides of the second U-shaped plate 66. Then, the cuttings are inserted through the gap between the first U-shaped mesh plate 63 and the second U-shaped mesh plate 610, and the soil-filled dish is filled with soil. When transplanting the seedlings of the thorny shoots, the soil-filled dish is taken out from the opening 51 by the handle 69. After removing the multiple long bolts 613, the connection between the first U-shaped frame 61 and the second U-shaped frame 65 is disassembled. Then, the soil clod formed by the soil is taken out along with the seedling for transplanting.

[0036] like Figures 7-8 As shown, a first U-shaped rubber block 614 is connected to the inner side of the first U-shaped mesh plate 63. The inner wall of the first U-shaped rubber block 614 is provided with multiple layers of first thin sheets 615. A second U-shaped rubber block 616 is connected to the inner side of the second U-shaped mesh plate 610. The inner wall of the second U-shaped rubber block 616 is provided with multiple layers of second thin sheets 617. The first U-shaped rubber block 614 and the second U-shaped rubber block 616 abut against each other.

[0037] Understandably, a large gap between the first U-shaped mesh plate 63 and the second U-shaped mesh plate 610 would cause a significant amount of soil-containing media to fall into the lower part of the constant temperature chamber 1, while a small gap would prevent the cuttings from passing through. Therefore, a first U-shaped rubber block 614 is connected inside the first U-shaped mesh plate 63, and a second U-shaped rubber block 616 is connected inside the second U-shaped mesh plate 610. After the first U-shaped frame 61 and the second U-shaped frame 65 are connected, the first U-shaped rubber block 614 and the second U-shaped rubber block 616 abut against each other. When the bottom of the cutting passes through the lower part of the constant temperature chamber 1, the cutting passes between the first U-shaped rubber block 614 and the second U-shaped rubber block 616. The cutting compresses multiple layers of the first thin sheet 615 and multiple layers of the second thin sheet 617, bending them to adapt to the size of the cutting and preventing a significant amount of soil-containing media from falling into the lower part of the constant temperature chamber 1.

[0038] like Figure 9As shown, it also includes multiple net baskets 8, each containing a filter screen. The net baskets 8 are placed inside the constant temperature chamber 1. The net baskets 8 are connected to multiple L-shaped hooks 81. The interface 51 contains multiple bayonets, and the L-shaped hooks 81 are connected to the bayonets. The soil stabilizing mechanism 6 is connected into the interface 51 and located inside the net baskets 8.

[0039] It is understandable that when the dispatching mechanism 7 delivers water or nutrient solution from the constant temperature box 1 into the soil-containing medium, a small amount of soil-containing medium from the soil-fixing mechanism 6 will fall into the lower part of the constant temperature box 1. If a large amount of soil-containing medium accumulates in the lower part of the constant temperature box 1, it will inevitably cause blockage. Therefore, by connecting the mesh basket 8 to the interface 51, and installing a filter screen inside the mesh basket 8, which is connected to the bayonet via an L-shaped hook 81, the space occupied at the connection point is reduced. After the soil-fixing mechanism 6 is connected to the interface 51, it is located inside the mesh basket 8. When the soil-containing medium from the soil-fixing mechanism 6 falls into the lower part of the constant temperature box 1, it enters the mesh basket 8 for collection. The filter screen blocks and limits the soil-containing medium. After the staff removes the mesh basket 8 from the interface 51, the fallen soil-containing medium can be cleaned up, thus preventing blockage caused by the soil-containing medium. Furthermore, the aquatic roots of the cuttings grow inside the mesh basket 8. The filter screen restricts the growth space of the roots, preventing them from intertwining with the aquatic roots of adjacent cuttings, thus ensuring the supply of water and nutrients to the cuttings.

[0040] like Figure 10 As shown, the dispatching mechanism 7 includes: A sealed box 71 is connected inside the bracket 2. The sealed box 71 is connected to a first connecting pipe 72, which is connected to the bottom end of the constant temperature box 1. A fifth solenoid valve 73 is provided on the first connecting pipe 72. The delivery pipe 74 is connected to the sealed box 71 at its tail end. The tail end of the delivery pipe 74 is close to the bottom of the inner side of the sealed box 71. The head end of the delivery pipe 74 is connected to the constant temperature box 1. The delivery pipe 74 is connected to a diversion pipe 75. Both ends of the diversion pipe 75 are closed. Multiple spray pipes 76 are connected to the diversion pipe 75. The spray pipes 76 are connected to the connecting frame 5. The ends of the spray pipes 76 are closed. Multiple connecting pipes are connected to the spray pipes 76. Self-adjusting nozzles 77 are connected to the connecting pipes. An oxygen pump 78 is connected inside the bracket 2, and the output end of the oxygen pump 78 is connected to the sealed box 71 through the second connecting pipe 79.

[0041] Understandably, when the water or nutrient solution in the constant temperature chamber 1 is injected into the soil medium, the controller controls the fifth solenoid valve 73 to open for a set time and then close. Part of the water or nutrient solution in the constant temperature chamber 1 enters the sealed chamber 71. Subsequently, the oxygenation pump 78 is started. The oxygenation pump 78 pumps air into the water or nutrient solution in the constant temperature chamber 1 through the second connecting pipe 79. After the air mixes with the water or nutrient solution, the oxygen content in the water or nutrient solution is increased. In addition, the air pumped in by the oxygenation pump 78 increases the pressure in the sealed chamber 71. After the pressure in the sealed chamber 71 increases, the water or nutrient solution in the sealed chamber 71 is transported into the diversion pipe 75 through the delivery pipe 74. After being diverted by the diversion pipe 75 to multiple spray pipes 76, it is sprayed into the soil medium by the self-adjusting nozzle 77. The self-adjusting nozzle 77 adjusts according to the pressure of the water or nutrient solution to ensure the uniformity of spraying the soil medium in the multiple soil stabilization mechanisms 6.

[0042] like Figures 11-12 As shown, the self-adjusting nozzle 77 includes: The nozzle 771 has a tapered section 772 at its head and a connecting pipe at its tail. A limiting cylinder 773 is installed inside the tapered section 772. An adjusting cylinder 774 is slidably connected inside the limiting cylinder 773. A pressure plate 775 is connected to the bottom end of the adjusting cylinder 774. The pressure plate 775 is located inside the tapered section 772. A spring 776 is installed inside the adjusting cylinder 774. One end of the spring 776 abuts against the limiting cylinder 773, and the other end of the spring 776 abuts against the pressure plate 775. The support frame 777 is connected to the nozzle 771. A flow divider 778 is connected inside the support frame 777. The flow divider 778 is set corresponding to the tapered pipe section 772.

[0043] Understandably, after the water or nutrient solution in the sealed box 71 enters the spray pipe 76, it then enters the spray pipe 771 through the connecting pipe. The water or nutrient solution impacts the pressure plate 775 and is sprayed out through the gap between the pressure plate 775 and the tapered pipe section 772. The sprayed water or nutrient solution then impacts the diversion plate 778 before being sprayed into the soil medium. The support frame 777 supports and fixes the diversion plate 778. Under the pressure of the water or nutrient solution, the regulating cylinder 774 adaptively expands and contracts within the limiting tank 773 via the spring 776. When the pressure of the water or nutrient solution increases, the regulating cylinder 774... When the section cylinder 774 contracts within the limiting barrel 773, the gap between the pressure plate 775 and the tapered pipe section 772 increases, and the water flow rate ejected from the tapered pipe section 772 increases, thereby reducing the pressure of the water or nutrient solution. When the pressure of the water or nutrient solution decreases, the spring 776 drives the regulating cylinder 774 to extend within the limiting barrel 773, and the gap between the pressure plate 775 and the tapered pipe section 772 decreases, thereby ensuring the water flow pressure ejected from the tapered pipe section 772. This adapts to the pressure changes within the sealing box 71, ensuring the uniformity of the spraying of soil media into the multiple soil stabilization mechanisms 6.

Then disinfect and treat the cuttings to promote root growth. The methods for disinfecting and promoting root growth of cuttings are as follows: Disinfect the cuttings by immersing the lower end in a 0.1% carbendazim solution for 10 minutes. After the cuttings have dried after being soaked and disinfected, immerse the lower end of the cuttings in the rooting powder solution for 60 seconds. After the soil stabilizing mechanism 6 is connected to the interface 51, the cuttings are inserted through the soil stabilizing mechanism 6, and the bottom of the cuttings enters the lower part of the constant temperature box 1 by 5cm-7cm. Then, the soil stabilizing mechanism 6 is filled with soil medium, and water is injected into the lower part of the constant temperature box 1 through the water level regulating mechanism 4. During the root germination period of 1-14 days, the water level adjustment mechanism 4 is set to not gradually adjust the water level height through the controller, the water in the constant temperature box 1 is replaced every 2 days, and the scheduling mechanism 7 is activated for 10 minutes every 4 hours. During the initial rooting period of 15-25 days, the water in the constant temperature box 1 is replaced with nutrient solution. The water level adjustment mechanism 4 is set by the controller to gradually adjust the water level. After the water level drops to the lowest point, the water level adjustment mechanism 4 immediately flows the nutrient solution back into the constant temperature box 1 and adjusts it gradually again. The nutrient solution in the constant temperature box 1 is replaced every 5 days. The scheduling mechanism 7 is started for 10 minutes every 4 hours. During the 26-40 day root establishment period, the water level regulating mechanism 4 gradually adjusts the water level. When the water level drops to the lowest point, after an interval of 6 hours, the water level regulating mechanism 4 recirculates the nutrient solution back into the constant temperature box 1 and performs gradual adjustment again. The nutrient solution in the constant temperature box 1 is replaced every 7 days. The scheduling mechanism 7 is activated for 15 minutes every 12 hours. During the 41-60 day transplanting period, the nutrient solution in the constant temperature box 1 is replaced with water. The water level adjustment mechanism 4 gradually adjusts the water level. When the water level drops to the lowest point, after an interval of 6 hours, the water level adjustment mechanism 4 recirculates the water back into the constant temperature box 1 and adjusts it gradually again. The water in the constant temperature box 1 is replaced every 7 days, and the scheduling mechanism 7 stops starting. Transplant the young shoots of Aralia elata during the transplanting period.
