Abstract
Description
Technical Field
[0001] This utility model relates to the field of plant cultivation technology, specifically a device based on plant root tropism induction. Background Technology
[0002] In plant science research, laboratory seedling cultivation is a fundamental and crucial task. It provides ideal experimental materials for research in multiple disciplines such as plant physiology, genetics, and molecular biology. Through the study of seedlings, scientists can gain a deeper understanding of the growth and development mechanisms of plants under different environmental conditions, such as photosynthesis, respiration, and hormone regulation. In the field of genetics, laboratory seedling cultivation helps to study gene function and expression regulation, providing a practical platform for gene editing, transgenic technology, and other technologies to cultivate new plant varieties with superior traits. In molecular biology research, seedlings are an important object for studying molecular mechanisms such as gene expression and protein synthesis.
[0003] In the process of cultivating seedlings in the laboratory, the growth status of plant roots has an important impact on the growth and development of seedlings and subsequent research results. However, current laboratory seedling cultivation methods often lack effective guidance for plant roots, which leads to irregular growth of seedling roots. Some roots tend to coil on the surface of the culture medium, forming shallow roots, which brings a series of problems. Although some deep and narrow containers are used for cultivation, different containers need to be changed during cultivation because different plants have different root growth requirements. Moreover, these deep containers are not convenient for subsequent transplanting.
[0004] In view of the above, this application is hereby submitted. Utility Model Content
[0005] The purpose of this invention is to provide a device based on plant root tropism induction to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides a device based on plant root tropism induction, including a box and cover plates movably disposed at both ends of the box along its own length at the top opening. The top of the cover plates has multiple vertically penetrating channels arranged in a rectangular array. A limiting mechanism is provided within each channel on the cover plate. The limiting mechanism includes:
[0007] The top plate is horizontally set, and the bottom plate is rotatably connected to the bottom plate. A locking ring is rotatably connected to the side wall of the bottom plate near the top plate. A ring-shaped rotating groove is opened on the side wall of the top plate near the bottom plate at the position corresponding to the locking ring. The locking ring rotates in the rotating groove on the top plate. A vertical through groove is opened on the top of the bottom plate and extends radially along the bottom plate.
[0008] A fixed column slides within a chute, with a guide plate rotatably connected to its end away from the top plate. A broken block is fixed on the circumferential side wall of the guide plate. The side wall of the cover plate away from the box is coated with a black coating. The horizontal cross-section of the guide plate is fan-shaped, and a cutting part is provided at the end of the guide plate away from the top plate.
[0009] Furthermore, a vertical through-passage II is provided at the center of the side wall of the top plate and the bottom plate that are close to each other, and a plurality of sliding grooves I are provided on the bottom plate in a circular array about the axis of the bottom plate, and a plurality of sliding grooves II are provided on the side wall of the top plate that is close to the bottom plate in a circular array about the axis of the bottom plate, with a one-to-one correspondence between the plurality of sliding grooves I and the plurality of sliding grooves II.
[0010] Furthermore, a vertically arranged sliding column slides within the sliding groove two on the top plate. A sliding plate is fixed to the bottom of the sliding column, and the sliding plate slides on the side wall of the bottom plate near the top plate. A fixed column is fixed to the side wall of the sliding plate away from the sliding column. The sliding groove two does not contact the rotating groove one. The sliding groove two is arc-shaped, with one end facing the channel two and the other end bent towards the outer edge of the top plate. A vertically penetrating channel three is opened at the top of the top plate corresponding to the position of the rotating groove one. The channel three communicates with the rotating groove. A handle is provided in the channel three, and a locking plate is fixed to the bottom of the handle. A locking ring is provided with meshing teeth on the side wall near the top plate, and the locking plate is provided with meshing teeth of the same structure on the side wall near the locking ring. The locking plate can mesh with the locking ring.
[0011] Furthermore, the fixed column and the guide plate are rotatably connected to each other via a damping shaft. The top of the top plate is flush with the top of the cover plate. Vertical through-holes are provided on both sides of the box along its length direction and at both ends along the width direction of the box. Rotating blocks are rotatably installed in the rotating slots. One end of the rotating block rotates in the middle of the rotating slot and the other end is rotatably connected to the cover plate. Multiple cover plates are provided on the top of the box. Rotating slots are provided on both sides along the width direction of the box on the side wall of two adjacent cover plates. The same rotating block is rotatably connected in the rotating slots three of two adjacent cover plates. The two cover plates near the middle of the box slide against each other on their adjacent sides. The two cover plates in the middle are rotatably provided with buckles on the same side wall along the width direction of the box.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. The guide plate in the limiting mechanism can effectively limit the excessive horizontal expansion of the seedling roots, forcing the roots to grow into the deeper layers of the culture medium. In the laboratory environment, the culture medium is usually relatively loose, and the roots tend to spread on the surface. The presence of the guide plate provides guidance for root growth, enabling the roots to penetrate into the substrate and form a deep root system. Through the design of the sliding column and the sliding groove, the position of the fixed column can be flexibly adjusted according to the root expansion needs of different growth stages of the seedlings or the different spaces required for root growth of different plants.
[0014] 2. The engagement of the locking ring with the handle and locking plate is controlled, thereby selecting whether to adjust the spacing of the guide plates or to directly loosen the soil near the plant roots by rotating the device body, thereby improving soil aeration and facilitating subsequent transplanting.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see the appendix Figure 1 To be continued Figure 5 This utility model provides a device based on plant root tropism induction: it includes a box body 10 and cover plates 11 movably disposed at both ends of the top opening of the box body 10 along its own length. The top of the cover plates 11 has multiple vertically penetrating channels arranged in a rectangular array. A limiting mechanism is provided within each channel on the cover plates 11. The limiting mechanism includes:
[0025] The top plate 20 is horizontally set, and the bottom plate 22 is rotatably connected to its bottom. A locking ring 21 is rotatably connected to the side wall of the bottom plate 22 near the top plate 20. An annular rotating groove is opened on the side wall of the top plate 20 near the bottom plate 22 corresponding to the position of the locking ring 21. The locking ring 21 rotates in the rotating groove on the top plate 20. A vertical through groove is opened on the top of the bottom plate 22 and extends radially along the bottom plate 22.
[0026] The fixed column 26 slides in the first groove, and the end of it away from the top plate 20 is rotatably connected to the guide plate 27. The guide plate 27 has a broken block 28 fixed on its circumferential side wall.
[0027] A vertical through-passage II is provided at the center of the side wall of the top plate 20 and the bottom plate 22 that are close to each other. Multiple sliding grooves I are provided on the bottom plate 22 in a circular array about the axis of the bottom plate 22. Multiple sliding grooves II are provided on the side wall of the top plate 20 that are close to the bottom plate 22 in a circular array about the axis of the bottom plate 22. Multiple sliding grooves I and multiple sliding grooves II correspond one to one.
[0028] A vertically arranged sliding column 25 slides within the sliding groove 2 on the top plate 20. A sliding plate 24 is fixed to the bottom of the sliding column 25. The sliding plate 24 slides on the side wall of the bottom plate 22 near the top plate 20. A fixing column 26 is fixed to the side wall of the sliding plate 24 away from the sliding column 25. The sliding groove 2 does not contact the rotating groove 1. The sliding groove 2 is arc-shaped, with one end facing the channel 2 and the other end bent towards the outer edge of the top plate 20.
[0029] The top plate 20 has a vertically penetrating channel 3 at the position corresponding to the rotating groove 1. The channel 3 is interconnected with the rotating groove. A handle 23 is provided in the channel 3. A locking plate is fixed at the bottom of the handle 23. The locking ring 21 has meshing teeth on the side wall near the top plate 20. The locking plate has meshing teeth with the same structure on the side wall near the locking ring 21. The locking plate can mesh with the locking ring 21.
[0030] It should be noted that: by restricting the horizontal expansion of the root system by the guide plate 27, the root system is forced to extend vertically, reducing lateral growth. The adjustable spacing of the guide plates 27 is used to control the root growth space in stages, avoiding insufficient guidance due to excessive space or excessive confinement due to insufficient space for the root system in the seedling stage, thus restricting root growth. The broken blocks 28 loosen the soil periodically with the root system growth, improving soil permeability and promoting microbial activity. In one possible embodiment, multiple guide plates 27 can form a semi-ellipsoid after abutting each other, so as to better guide the seedling roots.
[0031] The culture soil is placed in the box 10, and the pre-prepared plant seedlings are placed in the limiting mechanism. Then, the limiting mechanism and the seedlings are placed in the channel one, and the cover plate 11 is covered. The seedling roots grow downward through the channel two. The size of the box 10 can be changed according to the required volume of soil. When the multiple cover plates 11 are all horizontal and abut against each other, they can completely close the opening of the box 10. That is, the number of channels one in the whole composed of multiple cover plates 11 can also be changed according to the cultivation needs.
[0032] When the locking plate is not engaged with the locking ring 21, turning the handle 23 can drive the top plate 20 to rotate. The rotation of the top plate 20 drives the sliding column 25, the sliding plate 24, the fixed column 26, and the guide plate 27 to move synchronously centripetally or centrifugally along the sliding groove, thereby adjusting the spacing of the guide plates 27 to adapt to the root size of different plants. The breaking blocks 28 are set on the circumferential side wall of the guide plate 27, so that the nearby soil can be pushed away more easily when the guide plate 27 rotates.
[0033] When the locking plate engages with the locking ring 21, turning the handle 23 can drive the top plate 20 and the bottom plate 22 to rotate synchronously, thereby driving multiple guide plates 27 to rotate. Furthermore, the multiple guide plates 27 are all set away from the plant roots to avoid damaging the plant roots when rotating to loosen the soil. The axis of the arc wall of the guide plate 27 near the axis of the top plate 20 does not coincide with the axis of the top plate 20, and the guide plate 27 is deflected. In this way, when loosening the soil, not only can the nearby soil be pushed away, but the soil near the plant roots can also be replaced and exchanged.
[0034] Please see the appendix Figure 1 To be continued Figure 5The present invention provides a technical solution: the fixed column 26 and the guide plate 27 are rotatably connected to each other through a damping shaft, the top of the top plate 20 is flush with the top of the cover plate 11, and vertical through-rotation grooves are provided on both sides of the box body 10 along its length direction and at both ends along the width direction of the box body 10. Rotation block 12 rotates in the rotation groove 12, one end of rotation block 12 rotates in the middle of the rotation groove 12, and the other end is rotatably connected to the cover plate 11.
[0035] The top of the box body 10 is provided with multiple cover plates 11. On the side wall of two adjacent cover plates 11 that are close to each other, there are two rotating grooves 3 on both sides along the width direction of the box body 10. The same rotating block 2 13 is rotatably connected in the rotating grooves 3 on two adjacent cover plates 11.
[0036] Two cover plates 11 located near the middle of the box body 10 slide against each other on their adjacent sides, and two cover plates 11 located in the middle are provided with buckles 14 on the same side wall along the width direction of the box body 10.
[0037] The side wall of the cover plate 11 away from the box body 10 is coated with a black coating.
[0038] It should be noted that the interlocking of multiple cover plates 11 allows for quick opening and sealing of the box 10 opening for insulation in winter. The black coating can absorb heat from the sun. In summer, the coating of the cover plate 11 can be replaced with white to reduce heat accumulation and moisture loss through evaporation.
[0039] The buckle 14 allows for easy connection of the cover plates 11 at both ends of the top of the box body 10 to form a whole after the cover plate 11 is unfolded.
[0040] Working principle:
[0041] The container 10 holds the culture soil, and the cover plate 11 covers the opening of the container 10. A limiting mechanism is set in the first channel. The top plate 20 and the bottom plate 22 are connected through the second channel. The bottom plate 22 has a first sliding groove, and the top plate 20 has a second sliding groove. The sliding column 25 slides in the second sliding groove, which drives the sliding plate 24 and the fixed column 26 to move, adjusting the spacing of the guide plate 27. The guide plate 27 restricts the horizontal expansion of the root system and forces the root system to extend in the vertical direction, reducing lateral growth.
[0042] The handle 23 engages with the locking ring 21 via the locking plate, controlling the rotation of the top plate 20 and the bottom plate 22, which in turn drives the guide plate 27 to rotate and loosen the soil. The broken pieces 28 move with the guide plate 27 to assist in loosening the soil and improve air permeability. The splicing design of the cover plate 11 makes it easy to unfold the closed box 10. In winter, the black coating absorbs the heat from the sun and ensures that the temperature of the plant roots is as stable as possible.
