Description

Technical Field

[0001] This invention relates to the field of seedling cultivation technology, and in particular to a complete set of seedling cultivation equipment and seedling cultivation process. Background Technology

[0002] Currently, the spectacular seedling raising scene of the circulating motion seedling bed and its intelligent control interface highlight the sophistication of modern agricultural machinery. However, its pre-processing still relies on traditional agronomic methods. Manual labor is required for seed soaking and disinfection, sowing and germination, and transportation. To save labor and reduce costs, many projects equip seed bags with electric hoists from the seed soaking stage. Simple sowing sections utilize equipment such as seedling tray feeders, substrate and seed loading machines, seeders, tray stacking machines, roller (or belt) conveyors, and palletizing robots. Forklifts are then used to transport the stacked trays to a temperature- and humidity-controlled germination chamber. After 48 hours, forklifts are used to transfer the trays from the chamber to the seedling bed for seedling raising. Some projects, to demonstrate mechanization and automation, add robots to transfer seedling trays to a belt conveyor for transport to the front of the seedling bed, and further add robots to clamp the trays into the seedling bed's hanging baskets. However, this increased equipment consumption leads to increased costs and potential points of failure. Summary of the Invention

[0071] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0072] It should be noted that similar labels 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.

[0073] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0074] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0075] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0076] Please see Figures 1 to 9 This embodiment provides a complete set of intelligent seedling raising equipment, including a constant temperature oxygenation seed soaking device 1, a circulating seedling bed 2, a track-mounted soil-laying seeder 3, a humidification device 4, a telescopic greenhouse 5, and an intelligent adjustment device 6.

[0077] The constant temperature oxygenation seed soaking device 1 includes a water tank 11, a constant temperature component 12, an aeration component 13, and an inlet and outlet drainage component 14. The constant temperature component 12, the aeration component 13, and the inlet and outlet drainage component 14 are connected to the water tank 11.

[0078] The circulating seedling bed 2 includes a seedling bed frame 21, a circulating component 22, and a seedling tray 23 disposed on the circulating component 22. The circulating component 22 is movably connected to the seedling bed frame 21 to drive the seedling tray 23 to move along a first motion trajectory.

[0079] The track-mounted soil-laying seeder 3 is connected to the seedbed frame 21 and is located at one end of the first motion track. The track-mounted soil-laying seeder 3 is used to spread substrate or seeds into the seedling tray 23.

[0080] The humidification device 4 is connected to the seedbed frame 21 and is located at the other end of the first movement trajectory. It is used to apply water and fertilizer to the seedling tray 23.

[0081] The retractable greenhouse 5 includes a greenhouse support frame 51, a retractable top frame 52, and a first insulation film 53 that can be stored or laid around the greenhouse support frame 51. The retractable top frame 52 is movably connected to the top of the greenhouse support frame 51, and a second insulation film 54 is provided on the retractable top frame 52.

[0082] The intelligent regulating device 6 is connected to the constant temperature oxygenation seed soaking device 1, the circulating seedling bed 2, the humidification device 4, and the telescopic greenhouse 5.

[0083] The soaking process involves the seeds absorbing water. After absorbing water, the activity of seed enzymes increases, and under the action of enzymes, the endosperm starch gradually dissolves into sugar, releasing nutrients needed for the radicle, plumule, and hypocotyl. Seeds can only germinate normally after absorbing sufficient water. The time required to reach sufficient water absorption is affected by the soaking water temperature. Within a certain temperature range, the higher the temperature, the faster the seeds absorb water, and the shorter the time to reach saturation. Therefore, the seed soaking process is relatively cumbersome, and an intermittent soaking method is usually used, requiring repeated soaking and removal processes. Soaking is stopped after two to three days. The constant temperature and oxygen-enriched soaking device 1 provided in this embodiment allows water to be injected into the water tank 11 after the seeds are placed in the tank, submerging the seeds. Simultaneously, the aeration component 13 injects air into the water, enriching it with oxygen. The constant temperature component 12 also controls the water temperature, maintaining the water in the tank 11 within a certain temperature range to facilitate germination. After the seeds have been soaked for a period of time, the aeration component 13 and the constant temperature component 12 can stop working, and the water inlet and drainage component 14 will drain the water in the water tank 11, thereby draining the seeds in the water tank 11. After a period of time, the water inlet and drainage component 14 will continue to inject water to achieve intermittent soaking of the seeds.

[0084] The circulating seedling bed 2 is a circulating motion type seedling bed. The first motion trajectory can be a motion trajectory along the circumferential contour of the seedling bed frame 21, or it can be a linear reciprocating motion trajectory. In the embodiment provided in this implementation, the first motion trajectory is divided into upper and lower parts, such as... Figure 3 As shown, the lower part is a straight-line movement trajectory from the tail to the head of the seedbed frame 21, and the upper part is a curved movement trajectory from the head to the tail of the seedbed frame 21, moving up and down repeatedly. The track-mounted soil-laying seeder 3 is located above the head end of the straight-line movement trajectory. When the seedling tray 23 moves, it spreads soil substrate and seeds into the seedling tray 23. The humidifying device 4 is located above the tail end of the straight-line movement trajectory. When the seedling tray 23 moves, it can spray water vapor and fertilizer into the seedling tray 23. After the seedling tray 23 passes through the straight-line movement trajectory, excess water that has not been absorbed is drained. Then, it moves upward through the curved movement trajectory, preventing water from dripping from the upper tray to the lower tray. This would prevent water from splashing into the substrate and seeds in the seedling tray 23, creating holes, making the substrate surface uneven, exposing the seeds, and affecting seed germination and growth.

[0085] The seedling tray 23 can be a bottomless hanging basket, where workers can spread seeds and substrate and then place the tray in the bottomless basket. Alternatively, the seedling tray 23 can be a bottomed hanging basket with several drainage and ventilation holes at the bottom. One basket functions as a large seedling tray or as several seedling trays. The seedlings cultivated in this way can be rolled up entirely and used directly for machine transplanting in the field, or cut and rolled into smaller rolls according to preference and the transplanter model. The seedling tray 23 can also have a water-prevention structure, with multiple parallel grooves at the bottom, sloping along the length of the grooves. This allows water in the seedling tray 23 to be concentrated in the grooves for unified drainage.

[0086] Please see Figure 7 The top of the telescopic greenhouse 5 can be opened and closed. The second insulation film 54 is set on the top of the telescopic top frame 52. When the telescopic top frame 52 is retracted, the second insulation film 54 is retracted, allowing ventilation and lighting at the top of the greenhouse. When the telescopic top frame 52 is extended, the second insulation film 54 is extended simultaneously, sealing the top of the greenhouse. The first insulation film 53 on the side of the telescopic greenhouse 5 can also be retracted or extended to allow the greenhouse to be ventilated or sealed as a whole.

[0087] The intelligent regulating device 6 connects to the constant-temperature oxygen-enriched seed soaking device 1, the circulating seedling bed 2, the humidifier 4, and the retractable greenhouse 5. It can acquire data such as the water temperature and oxygen content in the water tank 11, the substrate humidity in the seedling tray 23, the fertilizer concentration applied by the humidifier 4, and the light intensity in the retractable greenhouse 5. It can also acquire data on the growth status of seeds or seedlings via cameras. After big data collection, the device uses programs or manual intervention to determine the optimal temperature, humidity, oxygen content, fertilizer concentration, and light intensity required for growth. It then controls the constant-temperature component 12, the aeration component 13, the humidifier 4, and the retractable greenhouse 5 to adjust these parameters, thereby achieving the optimal growth environment for the seeds or seedlings. The intelligent regulating device 6 may also include an intelligently adjustable spectrum LED light source to adapt to the different light sources required by different crops at different seedling stages.

[0088] The intelligent seedling raising equipment provided in this embodiment reduces equipment and logistics, and optimizes the structure and function of the circulating mobile seedling bed. It replaces the ordinary seed soaking method with a constant temperature, humidity, and oxygenation method, automatically changing water and removing free water during the process; it eliminates the need for expensive sowing lines, robots, forklifts, palletizing trays, and germination chambers; it directly uses a circulating seedling bed, with the track-mounted soil-laying seeder sowing synchronously with the seedling bed; the seedling trays can directly receive the soil and seeds from the seeder; humidification and fertilization are performed at the tail of the seedling bed frame, and oxygenation spraying or watering can be used for different seedling stages; the seedling bed uses a retractable greenhouse, with retractable cover for darkening and moisturizing, which promotes germination and is suitable for cultivating shade-loving crops, shortening the cultivation cycle; the intelligent adjustment device can establish a database during the seedling cultivation process, and use existing data and data from further experiments to model the temperature, humidity, light, air, and fertilizer requirements for crop growth and perform digital logic control. Integrating these functions achieves the goals of improving seedling quality, saving energy and labor, and intelligent cost reduction.

[0089] Furthermore, the track-mounted soil-laying seeder 3 includes a track 31, a soil-laying mechanism 32, a seeding mechanism 33, and a soil-covering mechanism 34.

[0090] There are multiple tracks 31, which are arranged side by side on the seedbed frame 21.

[0091] The soil spreading mechanism 32 is slidably mounted on the track 31 and includes a first buffer hopper 321 and a first spreading component 322. The first spreading component 322 is connected to the bottom of the first buffer hopper 321, and the first buffer hopper is used to hold the substrate.

[0092] The sowing mechanism 33 is slidably mounted on the track 31 and is located after the soil spreading mechanism 32 along the direction of movement of the seedling tray 23. It includes a second buffer hopper 331 and a second spreading component 332. The second spreading component 332 is connected to the bottom of the second buffer hopper 331, and the second buffer hopper 331 is used to place seeds.

[0093] The soil covering mechanism 34 is slidably mounted on the track 31 and is located after the sowing mechanism 33 along the direction of movement of the seedling tray 23. It includes a third buffer hopper 341 and a third spreading component 342. The third spreading component 342 is connected to the bottom of the third buffer hopper 341, and the third buffer hopper 341 is used to place the substrate.

[0094] The track 31 can be set perpendicular to the linear motion trajectory and parallel to the length direction of the seedling tray 23. When the seedling tray 23 moves below the track-laying seeder 3, the mechanism at this position can slide along the track 31, simultaneously spreading the substrate or seeds to evenly distribute the substrate or seeds along the length direction of the seedling tray 23. Please refer to [link to relevant documentation]. Figure 3The soil spreading mechanism 32, the sowing mechanism 33, and the soil covering mechanism 34 are arranged in front and behind along the direction of movement of the seedling tray 23. When the seedling tray 23 moves, the soil spreading mechanism 32 first spreads the soil substrate into the seedling tray 23, then the sowing mechanism 33 sows the seeds, and finally the soil covering mechanism 34 continues to spread the soil substrate to cover the lower substrate and the seeds together.

[0095] Further, please see Figure 2 In the implementation method provided in this embodiment:

[0096] The thermostatic component 12 includes an outlet pipe 121, a return pipe 122, and a heating module 123. One end of the outlet pipe 121 and the return pipe 122 are connected to the water tank 11, and the other end is connected to the heating module 123.

[0097] The aeration assembly 13 includes an aeration disc 131 and an isolation grid 132. The isolation grid 132 is located inside the water tank 11 to divide its internal space into a seed soaking chamber 111 and an aeration chamber 112. The aeration disc 131 is located inside the aeration chamber 112.

[0098] The water inlet and drainage assembly 14 includes an inlet pipe 141, a drain pipe 142, and a level controller 143. The inlet pipe 141 is connected to the seed soaking chamber 111, the drain pipe 142 is connected to the aeration chamber 112, and the level controller 143 is located on the inner wall of the water tank 11.

[0099] The outlet pipe 121 can transport water from the water tank 11 to the heating module 123. The heating module 123 heats the water and then the water is transported back to the water tank 11 by the return pipe 122. Since the water temperature in the upper part of the water body is lower, the outlet pipe 121 can connect to the upper part of the water tank 11 and the return pipe 122 can connect to the lower part of the water tank 11 so that the temperature of each part of the water body in the water tank 11 is uniform.

[0100] The isolation grid plate 132 has multiple holes and can be horizontally arranged inside the water tank 11, dividing the water tank 11 into an upper soaking chamber 111 and a lower aeration chamber 112. The isolation grid plate 132 connects the water in the soaking chamber 111 and the aeration chamber 112. However, because the holes in the isolation grid plate 132 are too small, the seeds are separated by the isolation grid plate 132. Therefore, when the water in the water tank 11 is drained by the water inlet and outlet assembly 14, the seeds will remain on the isolation grid plate 132, thereby achieving seed draining. There can be multiple aeration discs 131, which can be evenly distributed at the bottom of the water tank 11, i.e., inside the aeration chamber 112. The aeration discs 131 can be connected to a compressed air compressor through pipes to inject compressed air into the water to increase the oxygen content in the water.

[0101] The inlet pipe 141 can be connected to the upper layer of the water tank 11, and the drain pipe 142 can be connected to the lower layer of the water tank 11 to drain the water in the water tank 11. The liquid level controller 143 can be set at the required liquid level. When the water in the water tank 11 reaches the required liquid level, the inlet pipe 141 can be controlled to stop filling water.

[0102] Furthermore, the circulation component 22 includes a drive element 221, a drive wheel 222, and a drive belt 223.

[0103] The drive unit 221 is mounted on the seedbed frame 21.

[0104] There are multiple transmission wheels 222, which are mounted on the seedbed frame 21 and can be driven to rotate by the drive component 221.

[0105] The transmission belt 223 is looped around multiple transmission wheels 222, and the outer contour of the transmission belt 223 forms the first motion trajectory. The seedling tray 23 is placed on the transmission belt 223.

[0106] The driving component 221 can be a drive motor, and the transmission wheel 222 and transmission belt 223 can be a combination of sprockets and chains or a combination of pulleys and belts. There are two sets of transmission wheels 222 and transmission belt 223, which are respectively set on both sides of the seedbed frame 21. The two sets of transmission wheels 222 are rotatably connected to the two ends of the seedling tray 23. When the driving component 221 drives the transmission wheel 222 to rotate, the combination of the two sets of rotating wheels 222 and transmission belt 223 can drive the seedling tray 23 to move along the first motion trajectory.

[0107] Further, please see Figure 6 The humidification device 4 includes a water supply pipe 41, a fertilizer supply pipe 42, a spray pipe 43, and a spray head 44.

[0108] Water supply pipe 41 is connected to an external water source.

[0109] Connect fertilizer supply source to fertilizer pipe 42.

[0110] The spray pipe 43 is located above the seedling tray 23 and extends along the length of the seedling tray 23. The spray pipe 43 is connected to the water supply pipe 41 and the fertilizer supply pipe 42 through a three-way valve.

[0111] There are multiple spray heads 44, which are arranged along the extension direction of the spray pipe 43.

[0112] The three-way valve can be connected to the intelligent regulating device 6, and the intelligent regulating device 6 can control the three-way valve, thereby controlling the flow rate of the water supply pipe 41 and the fertilizer supply pipe 42, and thus controlling the fertilizer concentration in the sprayed water vapor.

[0113] Further, please see Figure 7 and Figure 8 In the embodiments provided in this implementation:

[0114] The greenhouse support frame 51 includes a support body 511 and a film roll storage structure 512. The film roll storage structure 512 is located on the support body 511, and the first heat insulation film 53 is connected to the film roll storage structure 512.

[0115] The telescopic top frame 52 includes a slide rail 521 and a movable rod assembly 522. The slide rail 521 is located on the top of the support body 511. One end of the movable rod assembly 522 is hinged to the slide rail 521, and the other end is slidably connected to the slide rail 521.

[0116] The main support 511 can be a square structure composed of multiple rods. There can be four roll film storage structures 512. The four roll film storage structures 512 are respectively set on the front, back, left and right end faces of the square structure and are located at the top of the four end faces, parallel to the top edge of the end face. The first heat insulation film 53 is connected to the roll film storage structure 512. When the roll film storage structure 512 rotates, the first heat insulation film 53 can rotate to be stored or rotated to be unfolded.

[0117] The movable rod assembly 522 can be composed of multiple staggered hinged rods. The movable rod assembly 522 can be connected to a drive structure. The drive structure can be located at one end of the movable rod assembly 522 hinged to the slide rail 521, or at the end of the movable rod assembly 522 that moves on the slide rail 521. The drive structure can be a drive motor, which drives one of the rods in the movable rod assembly 522 to swing, thus allowing the entire movable rod assembly 522 to swing, thereby retracting or expanding. Alternatively, the drive motor can be located at the end of the movable rod assembly 522, with its output end connected to a pulley, allowing the end of the movable rod assembly 522 to slide on the slide rail 521, thereby achieving the retraction and expansion of the movable rod assembly 522. The second insulation film 54 can be fixed to the top of the movable rod assembly 522. When the movable rod assembly 522 retracts or expands, the second insulation film 54 can simultaneously retract or expand.

[0118] Furthermore, the intelligent adjustment device 6 includes a temperature sensor 61, a humidity sensor 62, a light intensity sensor 63, a fertilizer application detection sensor 64, an oxygen content sensor 65, a seedling status monitor 66, and a processor 67.

[0119] Temperature sensor 61 is connected to water tank 11 and is used to obtain the water temperature in water tank 11.

[0120] Humidity sensor 62 is connected to seedling tray 23 to obtain soil moisture inside seedling tray 23.

[0121] The light intensity sensor 63 is connected to the retractable greenhouse 5 and is used to obtain the light intensity inside the retractable greenhouse 5.

[0122] The fertilizer application rate detection sensor 64 is connected to the humidification device 4 and is used to obtain the fertilizer concentration sprayed by the humidification device 4.

[0123] The oxygen content sensor 65 is connected to the water tank 11 and is used to obtain the oxygen content of the water in the water tank 11.

[0124] The seedling status monitor 66 is connected to the water tank 11, the circulating seedling bed 2, and the retractable greenhouse 5, and is used to obtain the growth status of the seeds in the water tank 11, the seedlings in the seedling tray 23, and the seedlings in the retractable greenhouse 5.

[0125] The processor 67 is connected to a temperature sensor 61, a humidity sensor 62, a light intensity sensor 63, a fertilizer application detection sensor 64, an oxygen content sensor 65, a seedling status monitor 66, a constant temperature component 12, an aeration component 13, a humidification device 4, and a retractable greenhouse 5. The processor 67 is used to record the parameters acquired by each sensor and to perform digital modeling by the program. The program analyzes or manually determines the parameters required for the optimal growth state of seeds or seedlings. The processor 67 controls the constant temperature component 12, the aeration component 13, the humidification device 4, and the retractable greenhouse 5 to adjust parameters such as water temperature, soil moisture, fertilizer concentration, and light intensity.

[0126] This embodiment also provides a seedling raising process, which employs the intelligent seedling raising equipment as described in any of the above embodiments. The seedling raising process includes the following steps:

[0127] Step 1: Place the seeds in the water tank 11. The water inlet and outlet components 14, aeration components 13 and constant temperature components 12 force the seeds in the water tank 11 to repeatedly switch between soaking and draining states. After the first time interval, the process stops. The intelligent adjustment device 6 obtains the water temperature, oxygen content in the water, and the first growth state of the seeds in the water tank 11.

[0128] Step 2: Place the seeds into the track-laying seeder 3. The track-laying seeder 3 spreads the seeds and substrate into the seedling tray 23. The circulation component 22 drives the seedling tray 23 to move along the first motion trajectory.

[0129] Step 3: The humidifying device 4 applies water and fertilizer to the seedling tray 23, and the intelligent regulating device 6 obtains the humidity in the seedling tray 23, the concentration of the applied fertilizer, and the second growth state of the seedlings.

[0130] Step 4: The seedlings are transferred into the retractable greenhouse 5 for cultivation. The intelligent adjustment device 6 obtains the light intensity inside the retractable greenhouse 5 and the third growth stage of the seedlings.

[0131] Step 5: The intelligent adjustment device 6 records the temperature, oxygen content, first growth state, humidity, fertilizer concentration, second growth state, light intensity and third growth state, and controls the constant temperature component 12, aeration component 13, humidification device 4 and telescopic greenhouse 5 after digital modeling.

[0132] In step 1, the first time interval can be two to three days, or it can be the time intelligently controlled after modeling various parameters obtained by the intelligent adjustment device 6. The water tank 11 can automatically change water and remove free water, so that the seeds can be automatically soaked and drained. In step 2, the substrate used by the track-laying soil seeder 3 can be a substrate or other materials. The track-laying soil seeder 3 can lay the substrate at the bottom of the seedling tray 23, and then lay the seeds and the covering soil layer on top of it. The covering soil layer covers the bottom substrate and seeds together. In step 3, the intelligent adjustment device 6 can obtain the applied fertilizer concentration through the spray structure connected to the humidification device 4. In step 5, the intelligent adjustment device 6 records the obtained parameters and performs digital modeling, so as to obtain the conditions required for the seeds or seedlings to reach the optimal growth state. It can control the growth conditions of the seeds or seedlings to reach the optimal growth state, and can also be used for cultivation experiments.

[0133] Furthermore, in the embodiments provided in this implementation:

[0134] The soaking state includes the water inlet and outlet component 14 filling the water tank 11 with water, the aeration component 13 injecting oxygen into the water, and the thermostat component 12 controlling the water temperature.

[0135] The draining state includes the water tank 11 being emptied by the inlet and outlet water inlet assembly 14, and the aeration assembly 13 and the thermostat assembly 12 stopping their operation.

[0136] When the seeds are soaking, the constant temperature component 12 and the aeration component 13 can make the temperature and oxygen content in the water reach the optimal value, which is conducive to the seeds absorbing water; when the seeds are draining, the seeds can fully contact oxygen, thereby realizing intermittent soaking of the seeds.

[0137] Furthermore, the track-mounted seeder 3 spreads the seeds and substrate into the seedling tray 23, specifically including the following steps:

[0138] Step 1: The circulation component 22 moves the seedling tray 23 to the first position, and the soil spreading mechanism 32 spreads the substrate in the seedling tray 23 to form a substrate layer.

[0139] Step 2: The circulation component 22 moves the seedling tray 23 to the second position, and the sowing mechanism 33 spreads the seeds on the substrate layer.

[0140] Step 3: The circulation component 22 moves the seedling tray 23 to the third position, and the soil covering mechanism 34 spreads the substrate on the substrate layer and covers the seeds.

[0141] The first position is below the location of the soil-laying mechanism 32, the second position is below the location of the sowing mechanism 33, and the third position is below the location of the soil-covering mechanism 34. Driven by the circulation component 22, the seedling tray 23 can be moved sequentially below the soil-laying mechanism 32, the sowing mechanism 33, and the soil-covering mechanism 34, where the soil-laying mechanism 32, the sowing mechanism 33, and the soil-covering mechanism 34 respectively perform soil-laying, sowing, and soil-covering.

[0142] Working principle:

[0143] Please see Figure 1 The seeds are first soaked and germinated by a constant temperature and oxygenation soaking device 1, and then sown on seedling trays 23 on a circulating seedbed 2 by a track-mounted soil-laying seeder 3. Then, the seeds are humidified and fertilized by a humidification device 4, and finally moved into a retractable greenhouse 5 for cultivation. The intelligent adjustment device 6 monitors the soaking, germination, humidification, fertilization and cultivation processes of the seeds.

[0144] Please see Figure 9 During the soaking and germination stage, temperature sensor 61, oxygen content sensor 65 and seedling status monitor 66 acquire the water temperature, oxygen content in the water and seed growth status in the water tank 11.

[0145] During the sowing, humidification and fertilization stage, humidity sensor 62 acquires the substrate humidity in seedling tray 23, fertilizer amount detection sensor 64 acquires the concentration of applied fertilizer, and seedling status monitor 66 acquires the growth status of seedlings in seedling tray.

[0146] During the cultivation stage inside the retractable greenhouse 5, the light intensity sensor 63 acquires the light intensity inside the retractable greenhouse 5, and the seedling status monitor 66 acquires the growth status of the seedlings inside the retractable greenhouse 5.

[0147] The processor records water temperature, oxygen content in the water, substrate humidity, fertilizer concentration, light intensity, and the growth status of seeds and seedlings, performs digital modeling, and determines the parameters required for seeds and seedlings to reach their optimal growth state. It then controls the constant temperature component 12, aeration component 13, humidification device 4, and retractable greenhouse 5 to achieve the best growth environment for seeds and seedlings.
