Technical Field
[0001] This utility model relates to the field of agricultural seedling technology, and more specifically to a salt-tolerant seedling bed for black goji berries. Background Technology
[0002] Black goji berry is a highly adaptable and salt-tolerant plant with excellent growth potential in some saline-alkali and arid regions. Its drought and salt tolerance makes it a preferred variety for ecological restoration of saline-alkali land and for economic crop cultivation. However, seedlings are sensitive to salt levels; therefore, selecting a suitable substrate is crucial for improving germination rate and growth during seedling cultivation.
[0003] Uneven salt penetration in ordinary seedbeds can easily lead to salt stress in seedling roots. Direct seedling cultivation in saline-alkali soil is prone to compaction, poor aeration, and low practicality. Therefore, we propose a salt-tolerant seedbed for black goji berries to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to solve the problems of uneven salt penetration in ordinary seedbeds, which easily leads to salt stress in the seedling roots, and the problems of direct seeding in saline-alkali land, which easily leads to compaction, poor air permeability, and low practicality. Therefore, this invention provides a salt-tolerant seedling bed for black goji berries.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A salt-tolerant seedling bed for black goji berries includes a box body with an outer enclosure. The box body has an inner seedling structure layer, which, from bottom to top, includes a drainage layer, a salt buffer layer, and a seedling layer. A porous support plate is provided at the bottom of the drainage layer. A horizontal groove is formed at the bottom of the box body, and vertical grooves are symmetrically formed on both outer walls of the box body. A lifting assembly is provided at the bottom of the box body, and the enclosure moves up and down via the lifting assembly to adjust the height and control the thickness of the seedling layer.
[0007] As a further description of the above technical solution, the lifting assembly includes a worm gear and a rotating rod rotatably installed in the horizontal groove. A turbine gear cooperating with the worm gear is provided at the middle position of the rotating rod. A driving bevel gear is symmetrically fixedly sleeved at both ends of the rotating rod. A lead screw is rotatably installed in the vertical groove. A driven bevel gear cooperating with the driving bevel gear is provided at the bottom end of the lead screw. A moving block is threadedly connected to one end of the lead screw located in the vertical groove.
[0008] As a further description of the above technical solution, the top end of the lead screw is connected to the housing bearing, and one side of the moving block is fixed to the bottom of the inner side of the enclosure.
[0009] As a further description of the above technical solution, a salt-shielding net is laid on the top of the seedling layer, an inclined guide plate is fixedly connected to the bottom of the inner cavity of the box, and a water outlet is provided on one side of the bottom of the box.
[0010] As a further description of the above technical solution, the thickness of the salt buffer layer is 15-20cm, and a salt sensor is embedded in the salt buffer layer. The salt sensor is electrically connected to an external alarm.
[0011] As a further description of the above technical solution, the drainage layer is composed of gravel or ceramsite, with a thickness of 5-10cm, and the bottom of the drainage layer is set as a slope.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] In use, this invention employs a layered salt control design to dynamically adjust the salt concentration in the root micro-zone. A drainage layer facilitates drainage and prevents water accumulation and salt backflow. A salt buffer layer absorbs excess salt. A salt-shielding net slows salt accumulation while maintaining light transmittance. The synergistic salt-reducing effect of biochar and salt-tolerant bacteria is utilized. Rotating a worm gear, which meshes with a worm wheel, drives a rotating rod. This rotating rod, in turn, drives a drive bevel gear. The meshing of the drive and driven bevel gears drives a lead screw, which in turn moves a moving block up and down along a vertical groove, thus raising and lowering the enclosure. Adjusting the height controls the thickness of the seedling layer, adapting to the root needs at different growth stages and enhancing the device's practicality. Attached Figure Description

[0020] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.
[0021] This utility model provides a salt-tolerant seedbed for black goji berries. Please refer to the following: Figures 1-5 As shown, the device includes a box body 1, an enclosure 2 on the outside of the box body 1, and a seedling structure layer 4 inside the box body 1. The seedling structure layer 4 includes a drainage layer 41, a salt buffer layer 42, and a seedling layer 43 from bottom to top. A porous support plate 44 is provided at the bottom of the drainage layer 41. A horizontal groove 8 is provided at the bottom of the box body 1, and vertical grooves 9 are symmetrically provided on the outer walls of both sides of the box body 1. A lifting component 6 is provided at the bottom of the box body 1. The enclosure 2 moves up and down by the lifting component 6 to adjust the height and control the thickness of the soil piled in the seedling layer 43.
[0022] In this embodiment of the application, the drainage layer 41 facilitates drainage and prevents water accumulation and salt return. The salt buffer layer 42 can absorb excess salt. The salt-shielding net 3 delays salt accumulation on the surface while maintaining light transmittance. The synergistic salt-reducing effect of biochar and salt-tolerant bacteria can be achieved. The thickness of the seedling layer 43 can be flexibly adjusted by adjusting the height of the enclosure 2, making it highly adaptable.
[0023] Furthermore, the lifting assembly 6 includes a worm gear 61 and a rotating rod 63 rotatably mounted in the horizontal groove 8. A turbine 62 that cooperates with the worm gear 61 is provided at the middle position of the rotating rod 63. A drive bevel gear 64 is symmetrically fixedly sleeved at both ends of the rotating rod 63. A lead screw 66 is rotatably mounted in the vertical groove 9. A driven bevel gear 65 that cooperates with the drive bevel gear is provided at the bottom end of the lead screw 66. A moving block 67 is threadedly connected to one end of the lead screw 66 in the vertical groove 9.
[0024] In use, by rotating the worm 61, the meshing of the worm 61 and the worm wheel 62 drives the rotating rod 63 to rotate. The rotating rod 63 drives the driving bevel gear 64 to rotate. The meshing of the driving bevel gear 64 and the driven bevel gear 65 drives the lead screw 66 to rotate. The lead screw 66 drives the moving block 67 to move up and down along the vertical groove 9, thereby driving the enclosure 2 to rise and fall. By adjusting the height, the filling thickness of the seedling layer 43 can be controlled to adapt to the root system needs at different growth stages.
[0025] Furthermore, a salt-blocking net 3 is laid on the top of the seedling layer 41, and an inclined guide plate 5 is fixedly connected to the bottom of the inner cavity of the box 1. A water outlet is provided on one side of the bottom of the box 1. The pore size of the salt-blocking net 3 is 0.5-1mm, which can reduce water evaporation and salt rise. The inclined guide plate 5 facilitates the drainage of water.
[0026] Furthermore, the salt buffer layer 42 is composed of a mixture of vermiculite, humus, and biochar. Vermiculite is a mineral with good water absorption and retention properties, improving soil structure. Humus is rich in organic matter, which can improve soil structure and fertility, providing organic nutrients. Biochar has a very strong adsorption capacity, which can effectively adsorb salt in the soil, reduce the adverse effects of saline-alkali land on plants, effectively reduce the toxic effects of salt, and promote the overall growth and development of plants. The thickness is 15-20cm. A salt sensor 7 is embedded in the salt buffer layer 42. The salt sensor 7 is electrically connected to an external alarm. The ratio of vermiculite:humus:biochar is 3:2:1. It adsorbs excess salt. The salt sensor 7 is a conductivity sensor, model DFRobotSEN0244, with a measurement range of 0-20 dS / m and an accuracy of ±2%. It measures the conductivity of the solution through electrodes, indirectly reflecting the salt concentration. When the detected value exceeds the set threshold, such as EC>3 dS / m, an audible and visual alarm is triggered.
[0027] Furthermore, the drainage layer 41 is composed of gravel or ceramsite with a thickness of 5-10cm. The bottom of the drainage layer 41 is set as a slope, and gaps are formed by stacking gravel or ceramsite to facilitate drainage and prevent water accumulation and salt backflow.
[0028] Furthermore, the seedling layer 43 is composed of sandy loam, coconut coir, and salt-tolerant bacteria. When using it, the ratio of sandy loam to coconut coir is 7:3. Before sowing, it is rinsed with a 0.3% CaSO4 solution to remove salt, resulting in a pH of 7.5-8.5 and an EC value ≤2.0 dS / m. Sandy loam has good drainage and aeration, helping to prevent waterlogging at the roots and ensuring root respiration. It also provides certain nutrients. Its loose structure helps the roots to take hold and promotes plant growth. Coconut coir is an organic material, rich in organic matter required for plant growth. It improves soil moisture retention and aeration, helps maintain soil looseness, and provides slow-release nutrients, which is beneficial for plant growth and root development. Salt-tolerant bacteria help improve soil salinity, decompose salt in the soil, and reduce the negative impact of salt on plants. Especially in saline-alkali soils, salt-tolerant bacteria can promote healthy plant growth and improve salt resistance.
[0029] The working principle of this utility model is as follows: During use, the drainage layer 41 facilitates drainage and prevents water accumulation and salt return. The salt buffer layer 42 can absorb excess salt. The salt-blocking net 3 delays salt accumulation on the surface while maintaining light transmittance. Through the synergistic salt-reducing effect of biochar and salt-tolerant bacteria, the worm gear 61 is rotated. The meshing of the worm gear 61 and the worm wheel 62 drives the rotating rod 63 to rotate. The rotating rod 63 drives the active bevel gear 64 to rotate. The meshing of the active bevel gear 64 and the driven bevel gear 65 drives the lead screw 66 to rotate. The lead screw 66 drives the moving block 67 to move up and down along the vertical groove 9, thereby raising and lowering the enclosure 2. The thickness of the seedling layer 43 is controlled by adjusting the height to adapt to the root needs at different growth stages.
[0030] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
