Description

Technical Field

[0001] The utility model relates to the technical field of seedling cultivation, in particular to a device for cultivating ginkgo seedlings. Background Art

[0002] Ginkgo biloba is a precious tree species with high ornamental and economic value. During the seedling cultivation process, a suitable growth environment must be provided to ensure the healthy growth of the seedlings. During the seedling transplantation process, vigorous lateral root growth plays a crucial role in improving the transplant survival rate. This is because lateral roots help the seedlings better absorb water and nutrients from the soil, thereby enhancing the seedlings' ability to adapt to the environment. When seedlings have well-developed lateral roots, they can more effectively stabilize the plant, reducing post-transplant shaking and damage. They can also better withstand changes in the external environment, such as drought and cold weather, which are key factors affecting transplant survival rates. Therefore, vigorous lateral root growth has a positive impact on improving transplant survival rates. Factors such as the moisture distribution and nutrient solution distribution in the seedling culture medium can affect the growth of seedling lateral roots. By regulating these factors, lateral root growth can be promoted. Some existing seedling cultivation devices cannot achieve this regulation, while others can, but the manufacturing cost of the control components is high and the transplantation of seedlings is inconvenient.

When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0032] like Figure 1-6As shown, the device for raising ginkgo seedlings comprises a base 1, which is preferably circular, but may also be in other shapes, such as a rectangle, a regular polygon, etc. A seedling raising cylinder 2 is provided above the base 1 through a rotating structure, and the seedling raising cylinder 2 can be rotated by the rotating structure, so that the ginkgo seedlings in the seedling raising cylinder 2 are illuminated in all directions, effectively avoiding the situation where the unilateral illumination is too long and causes the seedlings to grow in a biased direction. The seedling raising cylinder 2 is cylindrical and has openings at both the upper and lower ends. A transplanting rack 3 is detachably provided in the seedling raising cylinder 2. In the seedling raising stage, the transplanting rack 3 and the seedling raising cylinder 2 are together. After the seedling raising is completed, the transplanting rack 3 is disassembled to achieve non-destructive transplantation of the ginkgo seedlings.

[0033] The transplant rack 3 includes a support base plate 301, the diameter of which matches the inner diameter of the seedling cylinder 2, and the support base plate 301 is located at the bottom of the inner cavity of the seedling cylinder 2, so that the lower end of the seedling cylinder 2 can be shielded by the support base plate 301, which is convenient for adding culture medium without falling. The support base plate 301 is provided with a plurality of ventilation and water-permeable holes 302, through which excess water or nutrient solution can be discharged, thereby avoiding the adverse effects such as excessive water accumulation in the seedling cylinder 2 causing root rot of the ginkgo seedlings. In addition, when watering or adding nutrient solution, the outside air can enter the interior of the seedling cylinder 2 through the plurality of ventilation and water-permeable holes 302, thereby meeting the growth needs of the ginkgo seedlings.

[0034] The edge of the support base 301 is provided with a plurality of support vertical plates 303 by a hinge structure, and the plurality of support vertical plates 303 are evenly distributed at the edge of the support base 301. The number of the plurality of support vertical plates 303 is preferably four, and the upper end of each support vertical plate 303 is provided with a support block 304 and the two are perpendicular to each other, and each support vertical plate 303 is in contact with the inner side wall of the seedling cylinder 2;

[0035] An annular groove 4 is provided at the outer edge of the upper end surface of the seedling cylinder 2, a support ring 305 is provided in the annular groove 4, and the upper surface of the support ring 305 is flush with the upper end surface of the seedling cylinder 2, and multiple support blocks 304 are respectively in contact with the upper surface of the support ring 305. By clamping the multiple support blocks 304 on the support ring 305, the support base plate 301 can be fixed to the bottom of the seedling cylinder 2;

[0036] The transplant rack 3 is provided with a ring-shaped water-absorbing sponge 5, the outer side wall of the water-absorbing sponge 5 is in contact with a plurality of supporting vertical plates 303, and the inner side wall of the water-absorbing sponge 5 is evenly provided with a plurality of water-absorbing sponge strips 6 of equal height along its circumferential direction. The culture medium for cultivating ginkgo seedlings is located inside the ring-shaped water-absorbing sponge 5. The water-absorbing sponge 5 and the water-absorbing sponge strips 6 can absorb and store more water and nutrient solution. When the water or nutrient solution in the culture medium is gradually reduced, the water or nutrient solution stored in the water-absorbing sponge 5 and the water-absorbing sponge strips 6 will be absorbed by the drier culture medium nearby, and the culture medium in the middle position is closer to the water-absorbing sponge 5 and the water-absorbing sponge strips 6. When the water-absorbing sponge strips 6 are farther apart, the water or nutrient solution in the culture medium in the middle area will be less than the water or nutrient solution in the culture medium around the water-absorbing sponge 5 and the water-absorbing sponge strips 6. In this way, the lateral roots of the ginkgo seedlings can be induced to grow all around, thereby absorbing more water or nutrient solution to make the lateral roots of the ginkgo seedlings grow more vigorously. In addition, when the water or nutrient solution is less, the sponge has better air permeability, which makes the air permeability of the surrounding culture medium better, and also induces the lateral roots of the ginkgo seedlings to grow all around. Since multiple water-absorbing sponge strips 6 are evenly distributed, the lateral roots of the ginkgo seedlings can be made to grow all around to avoid entanglement. When transplanting, it is only necessary to pull the supporting ring 305 upwards, and then the multiple supporting blocks 304 can be pulled upwards at the same time, and then the supporting bottom plate 301 can be pulled out from the seedling cylinder 2 through the multiple supporting vertical plates 303. Since the ginkgo seedlings, the culture medium, and the ring-shaped water-absorbing sponge 5 are all located on the supporting bottom plate 301, the transplanting rack 3, the ginkgo seedlings, the culture medium, and the ring-shaped water-absorbing sponge 5 can be taken out together without damaging the root system of the seedlings. In addition, the ring-shaped water-absorbing sponge 5 isolates the culture medium from the seedling cylinder 2, avoiding the culture medium from becoming hardened and adhering to the seedling cylinder 2, further facilitating the transplanting rack, ginkgo seedlings, and the culture medium. The support ring 305 and the ring-shaped water-absorbing sponge 5 are taken out together. After the whole is taken out, the support ring 305 is removed, and then the upper ends of the multiple support vertical plates 303 are bent outward. Since the lower ends of the multiple support vertical plates 303 are fixed by a hinge structure, the multiple support vertical plates 303 can be separated from the ring-shaped water-absorbing sponge 5, so that the water-absorbing sponge 5, the ginkgo seedlings, and the culture medium are taken out as a whole for easy transplantation. Due to the wrapping of the ring-shaped water-absorbing sponge 5, the seedlings can be protected during transplantation to avoid collision and damage to the seedlings. In addition, the ring-shaped water-absorbing sponge 5 can be used for moisturizing, providing sufficient water to ensure the loss of water during transplantation and transportation.

[0037] like Figure 1 As shown, in this embodiment, as a preference, the rotating structure includes at least two support plates 7, the lower ends of the two support plates 7 are respectively fixedly arranged at the edge of the base 1 and are symmetrical about the central axis of the base 1;

[0038] Bearings 8 are provided at the upper ends of the two support plates 7. The inner ring of the bearing 8 is sleeved on the middle and lower part of the seedling cylinder 2. The outer ring of the bearing 8 is fixedly connected to the upper ends of the two support plates 7 respectively. The direction of the ginkgo seedlings in the seedling cylinder 2 can be changed by simply rotating the seedling cylinder 2, so that the ginkgo seedlings can be illuminated in all directions, avoiding the situation where the unilateral illumination is too long and causes it to grow in a biased direction.

[0039] like Figure 1 As shown, in this embodiment, in order to prevent the seedling cylinder 2 from rotating uncontrollably, a threaded hole is provided in the middle and upper part of one of the support plates 7, and a tightening screw 9 adapted thereto is provided in the threaded hole. The length of the tightening screw 9 is greater than the distance from the support plate 7 to the seedling cylinder 2, and a knob is provided at one end of the tightening screw 9. By turning the knob, the tightening screw 9 tightens the outer wall of the seedling cylinder 2 so that it cannot rotate freely, thereby realizing directional adjustment.

[0040] like Figure 1 As shown, in this embodiment, in order to avoid the added water or nutrient solution from flowing out and being wasted from the multiple ventilation and water-permeable holes 302, a water receiving shell 10 is provided on the base 1 and is located directly below the seedling cylinder 2. The inner diameter of the water receiving shell 10 is larger than the outer diameter of the seedling cylinder 2. The excess water or nutrient solution can be collected by the provided water receiving shell 10 for reuse to avoid waste.

[0041] like Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 As shown, in this embodiment, preferably, the support ring 305 includes a first semicircular ring 3051 and a second semicircular ring 3052;

[0042] The first semicircular ring 3051 is provided with a plug rod 11 on both side end faces, and the second semicircular ring 3052 is provided with a socket 12 adapted to the plug rod 11 on both side end faces. The two plug rods 11 correspond to the two sockets 12 respectively. When the first semicircular ring 3051 and the second semicircular ring 3052 together form a ring, the two plug rods 11 are respectively located in the two sockets 12 and the two are interference fit. Through the cooperation of the plug rods and the sockets 12, the first semicircular ring 3051 and the second semicircular ring 3052 can be disassembled, which facilitates the opening of multiple support vertical plates 303, and then facilitates the removal of ginkgo seedlings, culture medium, and water-absorbing sponge 5 together.

[0043] In this embodiment, as a preference, the water-absorbing sponge 5 and the plurality of water-absorbing sponge strips 6 are all made of degradable sponge, so that the ginkgo seedlings, the culture medium, and the water-absorbing sponge 5 can be transplanted as a whole without removing the water-absorbing sponge 5 and the plurality of water-absorbing sponge strips 6. The overall transplantation further improves the survival rate; in addition, the degradable sponge can also provide certain nutrients to the ginkgo seedlings after degradation, further promoting the growth of the roots of the ginkgo seedlings.

[0044] In this embodiment, in order to improve the stability of the seedling cylinder 2, the number of the support plates 7 is three, two of which are symmetrical about the central axis of the base 1, and the other one is located between the two support plates 7 and is equidistant from the support plates 7 on both sides, that is, three support plates 7 are evenly distributed on the length of the semicircular arc. The support of the three support plates 7 can effectively improve the stability of the seedling cylinder 2 without affecting the removal and placement of the water receiving shell 10.

[0045] In this embodiment, in order to enable the multiple support vertical plates 303 to fit better on the inner wall of the seedling cylinder 2, the multiple support vertical plates 303 are all in contact with the inner wall of the seedling cylinder 2 on a curved surface and the curvature of the curved surface is adapted to the curvature of the inner wall of the seedling cylinder 2. Through the design of the curved surface, the support vertical plates 303 can fit better on the inner wall of the seedling cylinder 2.

[0046] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
