Description

Technical Field

[0001] This invention belongs to the field of planting device technology, specifically relating to a planting device and method for improving the survival rate of bract-leaved snow lotus seedlings. Background Technology

[0002] *Saussurea involucrata* is a rare and precious alpine medicinal and protected plant. Its scarcity in the wild and the difficulty of artificial propagation, particularly the low seedling survival rate, are the core bottlenecks restricting its large-scale cultivation and resource conservation. Existing seedling cultivation devices and technologies generally suffer from the following defects: First, weak habitat simulation capabilities, failing to accurately replicate native environmental conditions such as glacial meltwater, low temperatures, and controlled light, leading to severe seedling stress; second, rigid environmental control, with fixed planting height, angle, and light range, making it difficult to adapt to the dynamic needs of seedlings at different growth stages; third, extensive irrigation methods, mostly single flood irrigation or sprinkler irrigation, with unadjustable water temperature and uneven water supply, easily causing root hypoxia and rot or drought wilting; fourth, poor structural stability and operability, with inconvenient assembly and disassembly of planting units, unreliable fixation, and low maintenance and transplanting efficiency; and fifth, low space utilization, making it difficult to meet the needs of large-scale, intensive seedling cultivation. These problems collectively result in high artificial seedling costs and low survival rates, severely limiting the industrial development and wild resource conservation of *Saussurea involucrata*.

[0003] Chinese Patent Publication No. CN103141293B discloses a method for large-scale cultivation to improve the survival rate of *Saussurea involucrata* seedlings, including the steps of seed selection; seed germination and warming; tissue culture seedling cultivation; transplanting to the field for survival; and planting management. The beneficial effects of this invention are: 1. Through the synergistic effect of seed-based nutrient cultivation and tissue culture seedling cultivation, it is more reliable than using only one method, preventing the limitations of single-seed cultivation in terms of quantity and season, and overcoming the disadvantage of tissue culture seedling cultivation alone, which results in the premature aging of the original plants and the inability to preserve robust plants for a long time, thus greatly improving the survival rate and number of *Saussurea involucrata* seedlings. 2. The nutrient substrate contains alpine meadow soil, meeting the nutritional needs and growth environment of *Saussurea involucrata* seedlings obtained through both seed and tissue culture cultivation.

[0004] Chinese Patent Publication No. CN109661980A discloses a method for cultivating Tian Shan Snow Lotus, comprising the following steps: seed selection, preparation of nutrient soil, sterilization and disinfection, use of agricultural fertilizers, seed germination, sowing, transplanting seedlings, topdressing, pest and weed control, and disease prevention. This cultivation method is simple and easy to implement, closely aligned with the growth habits of Tian Shan Snow Lotus. It provides a rational analysis of each step—seed collection, sowing, and seedling cultivation—based on the growth habits and environmental requirements of Tian Shan Snow Lotus. It can adapt to the environmental needs of Tian Shan Snow Lotus at different growth stages, providing different care and cultivation methods in the early, middle, and late stages of growth. It offers solutions to problems such as fertilization, watering, pest control, and disease prevention, thus meeting the growth needs of Tian Shan Snow Lotus. Furthermore, this method is low-cost, environmentally friendly, and uses farmyard manure instead of chemical fertilizers, resulting in less environmental pollution. It allows Tian Shan Snow Lotus to grow normally and healthily, is easy to cultivate in large quantities, and improves yield and quality.

[0005] Existing technologies for cultivating Saussurea involucrata seedlings suffer from inaccurate habitat simulation, rigid environmental control, unreasonable water supply, cumbersome equipment operation, insufficient stability, and poor adaptability to large-scale cultivation.

Snap-fit ​​springs are installed on both sides of the snap-fit ​​sliding rod. The two ends of the snap-fit ​​springs abut against the snap-fit ​​connecting plate and the snap-fit ​​fixing plate, respectively. The snap-fit ​​connecting plate connects the snap-fit ​​sliding plate and the snap-fit ​​block. The snap-fit ​​support plate is fixedly connected to one side of the snap-fit ​​fixing plate. The snap-fit ​​sliding plate is slidably connected to the middle of the snap-fit ​​support plate. A snap-fit ​​inclined plate is fixedly connected to one end of the snap-fit ​​sliding plate. The symmetrically distributed inclined surfaces of the snap-fit ​​inclined plates abut against each other. The snap-fit ​​pull plate is fixedly connected to the end of the snap-fit ​​sliding plate away from the snap-fit ​​inclined plate.

[0012] The locking post has a locking groove in the middle, and the locking blocks are symmetrically locked in the locking groove.

[0013] The lifting assembly includes a multi-stage telescopic rod, a lifting support plate, a lifting crossbeam, a lifting side plate, a lifting base plate, a lifting slide rail, a lifting connecting column, and a lifting slide plate. The multi-stage telescopic rod is fixed to the top of the lifting support plate, and the lifting support plate is fixed to the top of the multi-stage telescopic rod.

A lifting slide rail is provided in the middle of the lifting support plate. The lifting slide plates are slidably connected to the middle of the lifting slide rail. Both ends of the shelf are hinged to the lifting side plate.

[0014] The lighting assembly includes a lighting bracket, a lighting hinge column, a lighting hinge frame, a drive block, and a lighting plate. The lighting bracket is symmetrically placed at both ends of the main frame. The lighting hinge frame is connected to the lighting bracket through the lighting hinge column. The lighting plate is driven by the drive block and rotates to be connected to the lighting hinge frame.

[0015] The planting chamber is equipped with multiple temperature and humidity sensors in the middle.

[0016] A method for using a planting device to improve the survival rate of *Saussurea involucrata* seedlings: 1. Secure the main frame, install the lifting assembly, and test the smoothness of the lifting and rotation of the multi-stage telescopic rod, lifting side plate, and support frame; lay breathable non-woven fabric and fill it with suitable substrate into the planting chamber, and install the temperature and humidity sensor in the middle of the planting chamber; inject snow water into the snowmelt water tank, test the irrigation assembly, ensure that the delivery hose and branch pipes are leak-free, and that the water inlet and spray head are functioning normally, and preset the initial water temperature of the temperature control chamber; calibrate the lighting assembly, and adjust the lighting plate to the initial contraction state and corresponding flip angle using the drive block. Pull the snap-fit ​​plate to operate the snap-fit ​​assembly, and snap the planting chamber onto the snap-fit ​​column of the support frame using the snap-fit ​​assembly; 2. Dig planting holes in the substrate of the planting chamber, transplant the bract-leaved snow lotus seedlings, cover them with substrate and compact it. Lightly spray ice snow water through the sprinkler head to make the substrate and roots adhere. Adjust the height of the planting components using multi-stage telescopic rods, and adjust the tilt angle of the planting chamber using the hinged structure of the lifting side plate and the support frame; use the drive block to adjust the extension and tilt angle of the light plate to adapt to the light requirements of the seedlings at different growth stages. 3. Water from the snowmelt tank is pumped to the storage tank via a one-way pump, and then introduced into the temperature-controlled chamber through branch pipes. The temperature is controlled by adjusting the temperature control plate based on feedback from temperature and humidity sensors. Irrigation methods are switched between drip irrigation, spraying, or a combination of drip and spraying depending on the growth stage, with water supplied through the inlet and spray head. The temperature and humidity sensors collect substrate temperature and humidity data. In case of abnormalities, the lifting assembly adjusts the tilt angle of the support frame, and the irrigation assembly starts to replenish or drain water. The spray head and inlet are cleaned regularly, the elasticity of the snap-fit ​​springs of the snap-fit ​​assembly is checked, and the light intensity of the light panel and the water temperature accuracy of the temperature-controlled chamber are calibrated. In extreme environments, the temperature control plate, lifting assembly, and light panel of the temperature-controlled chamber are adjusted in coordination, or the vents and bypass valves are opened for emergency treatment.

[0017] 4. After the seedlings reach the standard for maturity, gradually adjust the irrigation frequency and the light board status to harden the seedlings; after hardening the seedlings, pull the locking plate to operate the locking component, so that the locking block is released from the locking groove, take out the planting chamber, and transplant the seedlings with the substrate to the planting site.

[0018] Compared with the prior art, the planting device and method of the present invention for improving the survival rate of bract-leaved snow lotus seedlings provides a stable support foundation for the main frame. The multi-stage telescopic rod and hinge structure of the lifting component are reliably connected with the snap-fit ​​component of the planting component. This ensures both the flexible and smooth adjustment of the height and angle of the planting chamber and the rapid disassembly and assembly through the precise snap-fit ​​of the snap-fit ​​block and the snap-fit ​​groove, thereby improving the efficiency of device assembly, maintenance and seedling transplantation, while avoiding the loosening and displacement of parts during operation.

[0019] The irrigation component's snowmelt water tank is designed to match the water source characteristics of the native habitat of the snow lotus. The temperature control chamber's temperature regulating plate is linked with temperature and humidity sensors to achieve precise control of water temperature and substrate temperature and humidity. The lighting component's lighting plate can be flipped and extended to adapt to the seedling's stage-specific lighting needs, comprehensively simulating a suitable high-altitude growth environment and reducing seedling stress.

[0020] The irrigation system integrates drip irrigation and sprinkler modes. The evenly distributed design of delivery hoses and branch pipes, along with the unidirectional pump, ensures a stable and leak-free water supply. The rotating sprinkler head expands the coverage area, and the targeted drip irrigation and air humidification work together to avoid water waste and substrate water accumulation, while meeting the root water replenishment and air humidity needs, reducing the risk of root rot and drought.

[0021] Temperature and humidity sensors collect real-time substrate environment data, providing a basis for adjusting the angle of the lifting components, regulating the light parameters of the lighting components, and switching the water temperature and irrigation mode of the irrigation components. This enables dynamic and precise adaptation of the growth environment, ensuring optimal growth conditions throughout the entire process from seedling adaptation to hardening-off period.

[0022] With the synergistic effect of multiple components, the uniformity of light exposure and the adaptability of moisture and temperature to seedlings are significantly improved, effectively solving the problems of poor stress resistance and environmental unsuitability of alpine seedlings after transplanting. The spaced layout of multiple planting chambers improves space utilization and is suitable for factory seedling production and field planting scenarios, ultimately greatly increasing the survival rate of bract-leaved snow lotus seedlings while reducing the cost of manual intervention, and has good practicality and promotion value.

[0026] like Figures 1 to 6 As shown, a planting device for improving the survival rate of *Saussurea involucrata* seedlings includes: a main frame 1, a lifting component 2, a lighting component 3, a planting component 4, and an irrigation component 5. The lifting component 2 is placed on top of the main frame 1, the lighting component 3 is symmetrically placed on both sides of the lifting component 2, multiple planting components 4 are intermittently and partially snapped onto the lifting component 2, the irrigation component 5 is placed on one side of the planting component 4, the lifting component 2 can change the height and angle of the planting component 4 by lifting, and the top of the lighting component 3 is provided with a retractable light panel 41 that can be flipped.

[0027] In this embodiment, the device has a modular layout, with each component having a clear division of labor and working together. The lifting component 2 can flexibly adjust the height and angle of the planting component 4, and the flip-out telescopic lamp plate 41 of the lighting component 3 can adapt to the lighting needs of different growth stages, effectively improving the uniformity of seedling light and environmental adaptability, laying a structural foundation for improving the survival rate.

[0028] The irrigation component 5 includes a snowmelt water tank 16, a delivery hose 17, a water storage tank 18, a branch pipe 19, a temperature control chamber 20, and a water inlet 25. The top of the snowmelt water tank 16 is connected to multiple delivery hoses 17. The end of the delivery hose 17 away from the snowmelt water tank 16 is connected to the water storage tank 18. A one-way pump is installed in the middle of the delivery hose 17. The temperature control chamber 20 is snapped onto one side of the planting component 4.

[0029] In this embodiment, the snowmelt water tank 16 is adapted to the water source characteristics of the native habitat of the bract-leaved snow lotus. The one-way pump and multi-stage pipeline ensure stable water supply. The temperature control chamber 20 precisely controls the water temperature through the temperature regulating plate. The water inlet 25 is directly inserted into the planting component 4 to achieve targeted drip irrigation, avoid water loss, reduce root stress response, and reduce the risk of root rot.

[0030] The irrigation assembly 5 also includes a spray branch pipe 21, a spray support plate 22, a spray branch pipe 23, and a spray head 24. The spray branch pipes 21 are evenly spaced and fixed on the top of the temperature control chamber 20. The spray support plate 22 is fixed to the top of the spray branch pipe 21. The spray branch pipes 23 are evenly spaced on the top of the spray support plate 22. The spray head 24 is placed at the front end of the spray branch pipe 23 and is rotatably connected to the spray branch pipe 23.

[0031] In this embodiment, the uniform distribution design of the spray branch pipe 21 and the spray sub-pipe 23 expands the spray coverage area. The rotating spray head 24 can flexibly adjust the spray angle to realize "drip irrigation + spraying" dual-mode irrigation, which can not only meet the substrate water replenishment needs, but also regulate air humidity and adapt to the water supply needs of seedlings at different growth stages.

[0032] The planting component 4 includes a planting chamber 42 and a snap-fit ​​component 43. The snap-fit ​​component 42 is fixed to the bottom of the planting chamber 42. The lifting component 2 has multiple hinged support frames 10 in the middle. The support frames 10 have multiple evenly spaced snap-fit ​​posts 26 in the middle. The snap-fit ​​component 43 snaps onto the snap-fit ​​posts 26.

[0033] In this embodiment, the snap-fit ​​assembly 43 and the snap-fit ​​post 26 engage to enable quick assembly and disassembly and secure fixation of the planting chamber 42. Multiple spaced-apart support racks 10 can simultaneously support multiple planting components 4, improving space utilization and facilitating subsequent seedling transplanting and device maintenance.

[0034] The snap-fit ​​assembly 43 includes a snap-fit ​​fixing plate 28, a snap-fit ​​support plate 29, a snap-fit ​​sliding plate 30, a snap-fit ​​pull plate 31, a snap-fit ​​sliding rod 32, a snap-fit ​​inclined plate 33, a snap-fit ​​connecting plate 34, a snap-fit ​​spring 35, and a snap-fit ​​block 36.

A sliding groove is opened in the middle of the snap-fit ​​fixing plate 28, and a snap-fit ​​sliding rod 32 is fixedly connected in the sliding groove. Snap-fit ​​springs 35 are installed on both sides of the snap-fit ​​sliding rod 32. The snap-fit ​​plate 34 and the snap-fit ​​fixing plate 28 are respectively abutted against the snap-fit ​​connecting plate 34 and the snap-fit ​​fixing plate 28. The snap-fit ​​connecting plate 34 connects the snap-fit ​​sliding plate 30 and the snap-fit ​​block 36. The snap-fit ​​support plate 29 is fixedly connected to one side of the snap-fit ​​fixing plate 28. The snap-fit ​​sliding plate 30 and the snap-fit ​​support plate 29 are slidably connected in the middle. One end of the snap-fit ​​sliding plate 30 is fixedly connected to the snap-fit ​​inclined plate 33. The inclined surfaces of the symmetrically distributed snap-fit ​​inclined plates 33 abut against each other. The snap-fit ​​pull plate 31 is fixedly connected to the end of the snap-fit ​​sliding plate 30 away from the snap-fit ​​inclined plate 33.

[0035] In this embodiment, the snap-fit ​​assembly 43 drives the snap-fit ​​block 36 to extend and retract through the elastic force of the snap-fit ​​spring 35. Combined with the inclined surface transmission of the snap-fit ​​inclined plate 33 and the manual operation of the snap-fit ​​pull plate 31, it realizes convenient switching between snap-fit ​​and unlocking. The structure is compact and the connection is reliable, preventing the planting chamber 42 from loosening and shifting during the operation of the device.

[0036] The snap-fit ​​post 26 has a snap-fit ​​groove 27 in the middle, and the snap-fit ​​block 36 is symmetrically snapped into the snap-fit ​​groove 27.

[0037] In this embodiment, the precise locking of the locking block 36 and the locking groove 27 further enhances the stability of the planting chamber 42. The symmetrical distribution design ensures balanced force distribution, avoids tilting or falling off caused by unilateral locking, and ensures the stability of the substrate and seedlings during the planting process.

[0038] The lifting assembly 2 includes a multi-stage telescopic rod 6, a lifting support plate 7, a lifting crossbeam 8, a lifting side plate 9, a lifting base plate 11, a lifting slide rail 12, a lifting connecting column 13, and a lifting slide plate 14.

The two ends of the shelf 10 are hinged to the lifting side plate 9.

[0039] In this embodiment, the multi-stage telescopic rod 6 enables precise height adjustment of the planting component 4. The hinged connection between the lifting side plate 9 and the support frame 10, and the sliding connection between the lifting slide plate 14 and the lifting slide rail 12, together enable flexible angle adjustment of the planting chamber 42. The transmission is smooth and the adjustment range is wide, adapting to the space requirements and environmental control requirements of different growth stages.

[0040] The lighting assembly 3 includes a lighting bracket 37, a lighting hinge column 38, a lighting hinge frame 39, a driving block 40, and a lighting plate 41. The lighting bracket 37 is symmetrically placed at both ends of the main frame 1. The lighting hinge frame 39 is connected to the lighting bracket 37 through the lighting hinge column 38. The lighting plate 41 is driven by the driving block 40 and rotates to connect with the lighting hinge frame 39.

[0041] In this embodiment, the hinged structure of the light support 37, the light hinge column 38, and the light hinge frame 39, together with the driving action of the driving block 40, enables the light plate 41 to flip and extend, which can precisely adjust the light angle, intensity and coverage, meet the staged light requirements of seedlings from the adaptation period to the hardening period, and improve the photosynthetic efficiency.

[0042] Multiple temperature and humidity sensors 15 are installed in the middle of the planting chamber 42.

[0043] In this embodiment, multiple temperature and humidity sensors 15 are evenly distributed, which can collect temperature and humidity data of the substrate in the planting chamber 42 in real time and accurately. This provides real-time feedback for water temperature adjustment of irrigation component 5, switching of irrigation mode, and angle adjustment of lifting component 2, so as to achieve dynamic and precise environmental control and reduce the risk of seedling death caused by abnormal temperature and humidity.

[0044] A method for using a planting device to improve the survival rate of *Saussurea involucrata* seedlings: 1.

[0045] 4. After the seedlings reach the standard for maturity, gradually adjust the irrigation frequency and the status of the light board 41 to harden the seedlings; after hardening the seedlings, pull the snap-fit ​​plate 31 to operate the snap-fit ​​component 43, so that the snap-fit ​​block 36 is disengaged from the snap-fit ​​groove 27, take out the planting chamber 42, and transplant the seedlings with the substrate.
