Description

Technical Field

[0001] This utility model relates to the field of mycorrhizal seedling cultivation, and in particular to a mycorrhizal seedling cultivation device with a high transplant survival rate. Background Technology

[0002] Mycorrhizal seedling cultivation refers to the process of artificially inoculating seedlings with mycorrhizal fungi, allowing the fungi to form a symbiotic relationship with the seedling roots, thereby cultivating seedlings with mycorrhizae.

[0003] First, it significantly enhances the nutrient absorption capacity of seedlings. The mycelium of mycorrhizal fungi expands the absorption area of ​​seedlings, penetrates deep into soil micropores, comes into contact with more nutrients, and decomposes organic matter, releasing nutrients that seedlings can absorb, thus improving nutrient utilization. Second, mycorrhizal seedling cultivation enhances the water absorption capacity of seedlings. The mycelium penetrates deep into the soil, absorbing more water and transferring it to the seedlings, enhancing their drought resistance and helping them maintain normal physiological functions under drought conditions. Furthermore, mycorrhizal seedling cultivation enhances the stress resistance of seedlings. Mycorrhizal fungi induce systemic resistance in seedlings, enhancing disease resistance, and by regulating physiological metabolism, improve the seedlings' tolerance to abiotic stresses such as high salt and heavy metal pollution. Mycorrhizal seedling cultivation also promotes seedling growth and development. Enhanced nutrient and water absorption accelerates seedling growth, improves root structure, increases root branching and lateral root formation, further promoting seedling growth. Simultaneously, mycorrhizal seedling cultivation improves the soil environment. The sticky substances secreted by the mycelium promote the formation of soil aggregates, improve soil structure, and increase aeration and water retention. The growth and activity of mycorrhizal fungi also increase soil microbial diversity, promote the richness and activity of soil microbial communities, and improve soil ecological functions.

[0004] In the prior art, for example, patent application CN119256812A discloses a mycorrhizal seedling cultivation container that facilitates experimental observation. This patent describes a container for mycorrhizal seedling cultivation that is convenient for experimental observation, consisting of a nutrient cup, a nutrient cup door, a nutrient cup door handle, a drainage hole, a black opaque plastic box, a perforated plastic plate, a plastic plate door, and a plastic plate door handle. The nutrient cup is made of transparent plastic to allow for easy observation of mycorrhizal growth. Each nutrient cup has a drainage hole at the bottom and an opening in the cup wall with a small, openable door for taking lateral roots for experimental observation. The nutrient cup is placed through a circular opening in the perforated plastic plate, with a rectangular opening in the center for observing watering. The opening also has a small, openable door. During the mycorrhizal seedling cultivation process, the seedling container is placed in the black opaque plastic box to simulate the dark environment of soil.

[0005] However, in actual use, the structure of this type of device restricts root extension. The nutrient cup mentioned in the patent is a truncated cone, wider at the top and narrower at the bottom, with a mouth diameter of 10cm, a bottom diameter of 7cm, and a height of 20cm. While this structure is beneficial for the extension of mycorrhizal seedling roots, the truncated cone shape may restrict root growth, preventing them from growing fully upright and leading to root curling. Insufficient root extension affects the plant's absorption of water and nutrients, thus impacting growth and development, and reducing the survival rate of transplanted seedlings. Secondly, the observation and sampling process can damage the roots. The nutrient cup has an opening with a small, operable door for sampling lateral roots. However, in practice, frequent opening of this door for sampling can damage the roots, especially those that have already formed mycorrhizal structures. Damaged roots reduce the plant's absorption capacity and resistance, affecting the overall health of the mycorrhizal seedlings and consequently impacting the transplant survival rate. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a mycorrhizal seedling cultivation device with a high transplant survival rate. The use of this device can achieve the effect of well-developed, upright, and non-curled plant roots, resulting in a high survival rate of transplanted seedlings.

[0007] To achieve the above objectives, this application discloses a mycorrhizal seedling cultivation device with high transplant survival rate, comprising a first box and a second box connected by a bottom hinge. The first box and the second box have the same structure and are symmetrically arranged. The device opens or closes as the first box flips relative to the second box. The first box includes a receiving space formed by a back plate, side walls, and a slope. The top of the receiving space is open and is divided into a straight section and a tapering section from top to bottom. The back plate corresponding to the straight section is provided with several spaced straight root-guiding protrusions, and the slope corresponding to the tapering section is provided with several spaced oblique root-guiding protrusions. The side walls include adjacent outwardly extending protrusions and inwardly recessed recesses. The top of the protrusions is provided with a notch, and the top of the recesses is provided with a protrusion. When the device is closed, the protrusions engage with the recesses on the opposite side, and the notches engage with the protrusions on the opposite side.

[0008] Furthermore, the straight guide root protrusions and the oblique guide root protrusions are arranged at equal intervals.

[0009] Furthermore, the cross-sections of the straight guide root protrusion and the oblique guide root protrusion are triangular.

[0010] Furthermore, the distance between any two adjacent straight guide root protrusions is less than the distance between any two straight guide root protrusions and the sidewall, and the distance between any two adjacent oblique guide root protrusions is less than the distance between any two oblique guide root protrusions and the sidewall.

[0011] Furthermore, the spacing between any two adjacent straight guide root protrusions is 1-2 times the width of the straight guide root protrusion itself, and the spacing between any two adjacent oblique guide root protrusions is 1-2 times the width of the oblique guide root protrusion itself.

[0012] Furthermore, an annular locking block is provided on the side of the protrusion near the sunken part, and a circular locking block is provided on the side of the protrusion near the notch.

[0013] Furthermore, the lower side of the slope is provided with a bottom, and the bottom is provided with a slot and a square block on both sides respectively.

[0014] Furthermore, a permeable groove is provided between the bottom card slot and the square card block at intervals.

[0015] Furthermore, the device consists of at least two sets of first and second boxes connected in parallel via bottom hinges.

[0016] Beneficial effects of the technical solution of this utility model

[0017] The unique structural design of this application is conducive to the healthy development of plant roots. The straight root-guiding protrusions on the first box and the straight section, as well as the oblique root-guiding protrusions on the tapering section 5, can effectively guide the plant roots to grow vertically downwards, avoiding curling and entanglement during the growth process. This allows the roots to extend more fully, increases the contact area between the roots and the soil, enhances the roots' ability to absorb water and nutrients, and provides a strong guarantee for the vigorous growth of the seedlings.

[0018] Secondly, the closed structure of the device helps to create a relatively stable seedling environment. When the device is closed, the first and second boxes work together to maintain the internal humidity and temperature to a certain extent, which is conducive to the symbiotic growth of mycorrhizae and seedling roots, promotes mycorrhizal infection and colonization of seedlings, and further improves the seedlings' resistance and adaptability.

[0019] Furthermore, this seedling raising device offers significant advantages during transplanting. Due to its well-developed and upright root system that prevents root curling, it minimizes root damage during transplanting, preventing stunted growth or seedling death caused by root injury. Simultaneously, its structure facilitates operation, opening and closing easily, which is beneficial for seedling removal and transplanting, greatly improving transplanting efficiency and survival rate, and reducing transplanting costs and labor intensity. It has significant application value for large-scale forestry production and landscaping. Attached Figure Description

[0030] refer to Figure 1-3 A mycorrhizal seedling cultivation device with high transplant survival rate includes a first box 100 and a second box 200 connected by a bottom hinge. The first box 100 and the second box 200 have the same structure and are symmetrically arranged. The device opens or closes when the first box 100 is flipped relative to the second box 200. The first box 100 includes a receiving space formed by a back plate 1, a side wall 2, and a slope 3. The top of the receiving space is open and is divided into a straight section and a tapering section 5 from top to bottom. The back plate portion 1 corresponding to the straight section is provided with several spaced straight guide root protrusions 6, and the slope portion 3 corresponding to the tapered section 5 is provided with several spaced oblique guide root protrusions 7; the side wall 2 includes adjacent outwardly extending protrusions 21 and inwardly recessed recessed portions 22. The top of the protrusion is provided with a notch 23, and the top of the recessed portion is provided with a protrusion 24. When the device is closed, the protrusion 21 engages with the recessed portion 22 on the opposite side, and the notch 23 engages with the protrusion 24 on the opposite side.

[0031] The first box 100 and the second box 200, serving as the main load-bearing components of the entire device, are connected by a bottom hinge, enabling the device to be opened and closed. This provides a relatively independent and controllable spatial environment for seedling cultivation, facilitating seedling management and transplanting. The back plate 1, together with the side walls 2 and the slope 3, constitute the main structure of the containing space, providing support and fixation for seedling growth. Simultaneously, the straight root-guiding protrusions 6 on the back plate guide the seedling roots to grow upright, preventing root curling. The side walls 2 include protrusions 21 and recessed sections 22. Their structural design helps enhance the structural strength and stability of the device. Furthermore, the notch 23 of the protrusions and the protrusion 24 of the recessed sections cooperate after the device is closed, further improving the sealing and fixation of the device and preventing soil and water loss during seedling cultivation.

[0032] The sloping section 3, together with the back plate section 1 and the side wall 2, forms the bottom structure of the containing space. The oblique root-guiding protrusion 7 on it can further guide the seedling roots to grow deeper, promote root development, and improve the seedling's resistance and adaptability. The opening is located at the top of the containing space, which facilitates the addition of soil, fertilizer, and water into the device, and also makes it easy to observe the growth of the seedlings.

[0033] The straight section provides relatively ample space for the initial growth of the seedling's root system, which is conducive to root extension and development. The gradually narrowing section 5 gradually guides the roots to grow deeper, preventing root curling and entanglement during growth and ensuring upright root growth. The straight root-guiding protrusions 6 and slanted root-guiding protrusions 7 are key components for achieving well-developed, upright, and non-curling root systems. Through their specific arrangement and shape design, they effectively guide the seedling's roots to grow downwards and upright, preventing root curling, while increasing the contact area between the roots and the soil, and improving the roots' ability to absorb water and nutrients.

[0034] The notch 23 and protrusion 24 further enhance the sealing and fixation of the device, preventing soil and water loss during seedling cultivation and ensuring normal seedling growth. The annular locking block 25 and circular locking block 26 enhance the connection strength and stability between the protrusion 21 and the protrusion 24, ensuring the device's robustness and reliability in the closed state. The bottom 8 serves as the base support structure for the entire device; its locking groove 81 and square locking block 82 allow for connection and fixation with other components, ensuring the overall stability of the device. The permeable trough 83 facilitates the drainage of excess water, preventing seedling roots from rotting due to water accumulation, while also ensuring ventilation and air permeability inside the device.

[0035] When in use, first flip the first box 100 and the second box 200 through the bottom hinge connection to open the device and create a relatively large space, which makes it easy to add soil, fertilizer and seedlings into the device.

[0036] Inside the opened device, first add an appropriate amount of soil, then place the sapling into the container, ensuring that the sapling's roots are in full contact with the soil. Then, add an appropriate amount of fertilizer and water as needed.

[0037] Flip the first box 100 and the second box 200 to the closed state, so that the protrusion 21 matches the sinking part 22 on the opposite side, and the notch 23 matches the protrusion 24 on the opposite side, forming a relatively closed space, which is conducive to maintaining the humidity and temperature inside the device and creating a good environment for the growth of seedlings.

[0038] After the device is closed, the seedling's roots grow vertically downwards under the guidance of the straight root guide protrusion 6 and the oblique root guide protrusion 7, preventing the roots from curling. At the same time, the humidity and temperature inside the device remain relatively stable, which is conducive to the growth and development of the seedling.

[0039] When the saplings have grown to a certain size and need to be transplanted, the device is opened and the saplings are taken out. Because the saplings have well-developed, upright roots that do not curl up, the root system is less damaged during transplanting, which can greatly improve the survival rate of the transplanted saplings.

[0040] In this embodiment, the straight root-guiding protrusions 6 and the oblique root-guiding protrusions 7, through their specific arrangement and shape design, effectively guide the seedling roots to grow vertically downwards, preventing root curling. Simultaneously, they increase the contact area between the roots and the soil, enhancing the roots' ability to absorb water and nutrients, thus achieving the effect of well-developed, upright, and non-curled root systems. The closed structure of the first box 100 and the second box 200, after the device is closed, forms a relatively enclosed space, which helps maintain the humidity and temperature inside the device, creating a favorable environment for seedling growth. It also prevents external interference and damage, improving the seedlings' resistance and adaptability, thereby increasing the transplant survival rate. The structural design of the side wall 2 includes the protrusions 21 and the recessed portion 22, as well as the cooperation of the notch 23 and the protrusions 24, further enhancing the sealing and fixation of the device, preventing soil and water loss during seedling cultivation, ensuring normal seedling growth, and also contributing to improving the transplant survival rate.

[0041] Preferably, the straight root-guiding protrusions 6 and the oblique root-guiding protrusions 7 are arranged at equal intervals. The equidistant root-guiding protrusions can provide uniform growth guidance for the plant roots, so that the roots are evenly distributed along the direction of the protrusions during growth, avoiding excessive aggregation or sparseness of roots in some areas, thereby ensuring uniform root development and improving the root system's absorption efficiency of nutrients and water in the soil.

[0042] refer to Figure 5 More preferably, the cross-section of the straight root-guiding protrusion 6 and the oblique root-guiding protrusion 7 is triangular. The triangular cross-section effectively guides plant roots to grow along the direction of the protrusion, making the roots more upright and deeper into the soil. This design helps prevent root curling and tangling, promoting healthy root development. The triangular protrusion increases the contact area between the roots and the soil, thereby improving the roots' ability to absorb water and nutrients. This helps the plant grow and develop better. The triangular protrusion reduces root damage during growth. Compared to protrusions of other shapes, the triangular protrusion applies more even pressure to the roots, preventing excessive stress and thus reducing root damage.

[0043] More preferably, the spacing between any two adjacent straight guide root protrusions 6 is less than the spacing between any two straight guide root protrusions 6 and the sidewall 2, and the spacing between any two adjacent oblique guide root protrusions 7 is less than the spacing between any two oblique guide root protrusions 7 and the sidewall 2. The spacing between any two adjacent straight guide root protrusions 6 is 1-2 times the width of the straight guide root protrusion 6 itself, and the spacing between any two adjacent oblique guide root protrusions 6 is 1-2 times the width of the oblique guide root protrusion 6 itself.

[0044] The spacing between adjacent straight root-guiding protrusions 6 is smaller than the spacing between them and the sidewall 2, and the spacing between adjacent oblique root-guiding protrusions 7 is smaller than the spacing between them and the sidewall 2. This design provides more ample growing space for plant roots. During growth, the roots can expand more effectively in all directions, avoiding root curling and mutual compression due to insufficient space, thus ensuring healthy root development. The spacing between the straight root-guiding protrusions 6 and the oblique root-guiding protrusions 7 is set to 1-2 times their width. This spacing effectively guides the roots to grow along the direction of the protrusion. The straight root-guiding protrusions guide the roots to grow upright downwards, while the oblique root-guiding protrusions guide the roots to grow obliquely downwards. The two work together to maintain a certain distance between the roots during growth, preventing them from intertwining and enhancing the root guidance effect.

[0045] Based on the above embodiment, an annular locking block 25 is provided on the side of the protrusion 21 near the recessed portion 22, and a circular locking block 26 is provided on the side of the protrusion 24 near the notch 23. A bottom 8 is also provided on the lower side of the slope portion 4, and a locking groove 81 and a square locking block 82 are respectively provided on both sides of the bottom 8.

[0046] An annular locking block 25 is disposed on the side of the protrusion 21 near the recessed portion 22, and a circular locking block 26 is disposed on the side of the protrusion 24 near the notch 23. When the device is closed, these locking blocks further enhance the stability of the fit between the protrusion 21 and the recessed portion 22, and between the notch 23 and the protrusion 24. Through the locking action of the locking blocks, accidental opening of the device due to vibration or other external forces during use can be prevented, ensuring the sealing and structural stability of the device.

[0047] The design of the ring-shaped and circular locking blocks makes the assembly and disassembly of the device more convenient. During assembly, simply align the locking block with the corresponding slot or notch and gently press or rotate to complete the connection; during disassembly, simply apply a certain force to remove the locking block from the slot or notch, without the need for complicated tools or operations, thus improving the ease of use of the device.

[0048] The slots 81 and square blocks 82 are located on both sides of the bottom 8, used to connect and secure the bottom 8 to other components. The cooperation of the slots and blocks ensures a tight connection between the bottom 8 and the slope 4, as well as other related components, enhancing the structural stability of the entire device. The cooperation of the slots 81 and square blocks 82 effectively prevents soil and water leakage from the gaps between the bottom 8 and other components, maintaining humidity and temperature inside the device and creating a favorable environment for plant root growth.

[0049] In a more preferred embodiment, a permeable trough 83 is further provided between the slot 81 and the square block 82 of the bottom 8. The permeable trough 83 provides good drainage performance for the bottom 8. During seedling cultivation, excess water can be drained through the permeable trough 83, preventing water accumulation inside the device and preventing root rot caused by prolonged immersion in water, thus ensuring healthy root growth. The permeable trough 83 also has an aeration function. Through the permeable trough 83, the air inside the device can exchange with the outside air, ensuring oxygen supply inside the device, which is beneficial to root respiration and promotes root growth and development.

[0050] refer to Figure 4 The device consists of at least two sets of first boxes 100 and second boxes 200 connected in parallel via bottom hinges. For example, a four-box configuration. This arrangement offers several important advantages. First, this parallel design significantly improves space utilization efficiency, facilitating centralized management and large-scale seedling cultivation, while saving space and reducing unit seedling costs. Second, multiple parallel boxes can share the same environmental conditions, ensuring seedlings grow under consistent conditions, promoting the spread and colonization of mycorrhizal fungi, and further improving seedling growth quality and transplant survival rate. Furthermore, this design reduces waste and promotes ecological cycles through centralized resource utilization, resulting in significant ecological benefits. In terms of economic and social benefits, the modular, parallel device is easy to promote and apply, suitable for large-scale forestry production, landscaping, and ecological restoration projects, reducing equipment investment costs and improving economic efficiency, thus showing promising prospects for widespread adoption.
