Description

Technical Field

[0001] The invention relates to the technical field of Dalbergia odorifera germplasm preservation equipment, and in particular to a Dalbergia odorifera germplasm preservation device and a method thereof. Background Art

[0002] Dalbergia odorifera, also known as Dalbergia odorifera, Dalbergia odorifera, is a tropical evergreen tree species belonging to the Leguminosae family. It is endemic to China and is mainly distributed in Hainan Island, China. It has also been introduced to Guangdong, Guangxi, Fujian and other places. "Dalbergia odorifera germplasm conservation" refers to the preservation and protection of Dalbergia odorifera's genetic resources through a series of scientific methods and technical means so that it can continue to be propagated, studied or used in the future. This conservation work usually includes seedling preservation and breeding. At present, the methods of preserving the germplasm of forest trees are mainly planting preservation, in vitro preservation, gene preservation, and germplasm resource bank preservation. Among them, planting preservation requires a large area of ​​forest land; although the area required for in vitro preservation and germplasm resource bank preservation (seeds) is smaller, they require corresponding technical support. The in vitro technology of Dalbergia odorifera has not been systematically studied and reported, and Dalbergia odorifera belongs to the stubborn type of seeds. Most of its seeds are sown as soon as they are collected, and the preservation time is not long. Therefore, in order to delay the growth of Dalbergia odorifera seedlings and maximize the use of space resources, a hydroponic in vitro rack (or vertical hydroponic system) is now used. This design can cultivate more Dalbergia odorifera seedlings in the smallest area. This design can delay the growth of Dalbergia odorifera seedlings. Dalbergia odorifera seedlings can grow normally and healthily in the culture container, but the seedlings grow slowly. At the same time, in order to improve the utilization rate of space, a three-dimensional rack is used. This design effectively solves the problem of large area occupied by traditional hydroponic facilities, and is especially suitable for places with limited land or tight space. At present, in the three-dimensional hydroponic system, the height of each layer of the hydroponic box is usually fixed. However, when the growth differences between individual seedlings are large, especially for some plants that require special care, the fixed-height hydroponic system cannot be adjusted according to the growth needs of individual plants, which will cause some seedlings to grow poorly due to narrow space, restricted root systems and other problems. At the same time, traditional hydroponic racks usually have a fixed height and width design, which means that when the hydroponic rack is installed in a small space, or the arrangement of the rack needs to be adjusted according to specific needs, the fixed size cannot make full use of the limited space, resulting in a waste of resources. Summary of the invention

[0036] Example

[0037] like Figures 1 to 8As shown, a Dalbergia odorifera germplasm preservation device proposed by the present invention comprises a water storage tank 1, and also comprises: a bottom rod 4 movably mounted at both ends of the water storage tank 1, and a top frame 5 movably connected to the top of the bottom rod 4; and a plurality of hydroponic boxes 6, wherein the hydroponic box 6 is a container or equipment for hydroponic planting, and is usually used for soilless plant cultivation. Hydroponic cultivation is to replace the traditional soil planting method by directly immersing the roots of plants in a water solution containing nutrients. The function of the hydroponic box 6 is to provide an environment suitable for plant growth and ensure that the plants can absorb sufficient nutrients from the water. A bracket 64 is fixedly connected to the inside of the hydroponic box 6, and a support plate 65 is movably provided on the bracket 64, and a plurality of hydroponic holes 63 are opened on the support plate 65, and the hydroponic holes 63 are used to place the roots of plants or the holes of the planting container. These holes are usually located above or on the inner plate of the hydroponic box 6, and are designed to be of a specific size and shape to support the growth of plants and ensure that the roots of plants can contact water and nutrient solution. The upper and lower parts are arranged correspondingly just above the water storage tank 1; the block mechanism is fixedly connected to both ends of the hydroponic box 6 so that the hydroponic box 6 is fixed on the bottom rod 4 and the top frame 5 at a specified height; the pinching mechanism is arranged at both ends of the hydroponic box 6 so that the hydroponic box 6 can be slidably adjusted on the bottom rod 4 and the top frame 5. In the hydroponic system, light is a key factor in plant growth. The height differences of plants often lead to different light requirements. If there is no flexibility in adjusting the height, short seedlings will not get enough sunlight due to obstruction, while tall seedlings will block the light of other plants due to their large size. By adjusting the layer spacing of the shelf according to the height of the seedlings, it can be ensured that each seedling can receive appropriate light. For example, tall plants are placed on a higher level, while short plants are placed below, so as to maximize the use of natural light sources and reduce light competition; a first pipeline mechanism is arranged on the water storage tank 1 to transport water to multiple hydroponic boxes 6; a water tank 11 is opened on the water storage tank 1, and multiple hydroponic boxes 6 are provided with a second pipeline mechanism for draining water overflowing from the hydroponic boxes 6 into the water tank 11 for recycling.

[0038] Hydroponic method of Dalbergia odorifera seeds

[0039] Step 1: Soaking seeds and germinating

[0040] From November to December every year, select superior mother plants with good stem shape, strong growth, full fruit, and no pests and diseases to collect seeds. The mature Dalbergia odorifera pods are yellow-brown or brown-brown. The picked pods are naturally dried in the shade for 1-2 days until the pod wings can be rubbed by hand. Select Dalbergia odorifera seeds with full fruit, and remove the shrunken and unhealthy seeds. Then soak the selected seeds in clean water for 24 hours. Then place the seeds in a germination box padded with double-layer filter paper for germination.

[0041] Step 2: Hydroponics

[0042] When the seeds germinate to more than 3 cm from the root and the cotyledons extend to true leaves, the seedlings are transferred to the hydroponic device. Further, the seeds can be grown only with tap water, and Hog l and nutrient solution (a commonly used plant nutrient solution formula, widely used in hydroponic and experimental research of plants, especially for plant growth research and plant cultivation under laboratory conditions) is added in time according to the growth of the seedlings and growth needs.

[0043] Furthermore, the pinching mechanism includes a handle block 7 fixedly connected to the outer wall at both ends of the hydroponic box 6, and a pair of support rods 71 ​​are fixedly connected to the handle block 7, and a clamping head 72 for clamping the pinching block 74 is fixedly connected to the end of the support rod 71 away from the handle block 7, and the clamping head 72 is used to prevent the pinching block 74, which is bounced by the push spring 73, from slipping out of the support rod 71. The support rod 71 is sleeved with a push spring 73, and the push spring 73 makes the pinching block 74 return to the state of abutting against the clamping head 72 on the support rod 71, and then makes the insert block 77 not abut against the anti-slip block 83, so that the hydroponic box 6 is firmly on the bottom rod 4 and the top frame 5. A pair of support rods 71 ​​are slidably sleeved with a pinching block 74 at one end away from the handle block 7, and the pinching block 74 is provided with a plurality of grooves that fit with fingers, so that the fingers pinching the pinching block 74 is more stable and comfortable.

[0044] The block mechanism includes a support block 8 fixedly connected to the outer walls of both ends of the hydroponic box 6, and a U-shaped groove slidably connected to the bottom rod 4 and the top frame 5 is provided at one end of the support block 8 away from the hydroponic box 6, and mounting holes 451 are provided on the bottom rod 4 and the top frame 5. A sliding slot 81 for inserting the insert block 77 is provided on the support block 8, and a sliding protrusion 82 whose end movably passes through the U-shaped groove and is inserted into the mounting hole 451 is slidably connected inside the sliding slot 81, and an anti-slip block 83 is fixedly connected to one end of the sliding protrusion 82 inserted into the sliding slot 81, and a reset spring 84 is fixedly connected to the one end of the anti-slip block 83 away from the sliding protrusion 82, and the reset spring 84 makes the sliding protrusion 82 always slide toward the U-shaped groove under normal conditions, and at the same time, always be locked in the spiral slot 41. The end of the return spring 84 away from the anti-slip block 83 is fixedly connected to the inner wall of the sliding slot 81, and the end of the insertion block 77 close to the sliding protrusion 82 is provided with a groove 78 for resisting the anti-slip block 83 and driving the sliding protrusion 82 to retract into the sliding slot 81. The groove 78 allows the end of the insertion block 77 to resist the anti-slip block 83 while the sliding protrusion 82 will not get stuck in the end of the insertion block 77 after being inserted into the groove 78.

[0045] Secondly, the first pipeline mechanism includes a water receiving sleeve 2, and an installation groove 12 is opened on the upper surface of the water storage tank 1. A water pump 13 is arranged inside the installation groove 12. The water outlet of the water pump 13 is fixedly connected with a water outlet pipe 15. The end of the water outlet pipe 15 connected to the water receiving sleeve 2 can be tightened by a cable tie to prevent loosening and detachment. The water inlet of the water pump 13 is fixedly connected to the water inlet pipe 14, and the end of the water inlet pipe 14 away from the water pump 13 is fixedly connected to the L-shaped water pumping pipe 16. The end of the L-shaped water pumping pipe 16 away from the water inlet pipe 14 movably penetrates the water storage tank 1 and is movably connected to the inner bottom wall of the water storage tank 11. The top of the water outlet pipe 15 is movably sleeved with the bottom end of the water receiving sleeve 2, and the top of the water receiving sleeve 2 is fixedly connected to the first transverse tube 21. The first transverse tube 21 is provided with a plurality of first corrugated hoses 22 corresponding to the hydroponic box 6.

The hydroponic box 6 is provided with an overflow pipe plug 62, and the end of the first sleeve 23 away from the first corrugated hose 22 is movably sleeved with the corresponding overflow pipe plug 62.

[0046] Furthermore, the second pipeline mechanism includes a connection port 19 fixedly connected to the water storage tank 1 and connected to the water storage tank 11.

The top of the water delivery sleeve 3 is fixedly connected with a second transverse tube 31, and the second transverse tube 31 is provided with a plurality of second corrugated hoses 32 corresponding to the hydroponic box 6. The first corrugated hose 22 and the second corrugated hose 32 are corrugated hoses, and the corrugated hose is a tubular object made of plastic, metal or composite material, and its outer surface has a corrugated wall structure. This special design of the corrugated hose makes it have good flexibility and scalability, and can bend, stretch and shrink under a certain pressure, and is widely used in occasions requiring flexible connection and transmission. The top of the second corrugated hose 32 is fixedly connected with a second sleeve 33, and the inside of the hydroponic box 6 is provided with a mounting pipe plug 61, and the bottom end of the mounting pipe plug 61 is movably sleeved with the corresponding second sleeve 33.

[0047] Furthermore, the top of the bottom rod 4 and the top frame 5 are both provided with a spiral slot 41, and the end of the top frame 5 away from the spiral slot 41 is fixedly connected with a spiral plug 51 that is spirally connected to the spiral slot 41.

The material of the connecting sleeve 43, the water receiving sleeve 2 and the water delivery sleeve 3 is rubber, which can increase the sealing when connected with the corresponding pipeline, and the material has elasticity, and can achieve a better sealing effect when tied with a cable tie. The end of the connecting sleeve 43 after being connected to the mounting block 18 can be tightened by a cable tie to prevent loosening and detachment. The outer walls of both ends of the water tank 1 are fixedly connected with mounting blocks 18 that are movably sleeved with the connecting sleeve 43. The bottom end of the water tank 1 is also fixedly connected with a pair of bottom frames 42, and the bottom frames 42 make the bottom end of the bottom rod 4 more stable. The upper surfaces of both ends of the water tank 1 are fixedly connected with handles 17, and the handles 17 make the disassembled water tank 1 more labor-saving when transporting.

[0048] The present application provides a method for using a Dalbergia odorifera germplasm storage device, such as Figure 1-Figure 8 As shown, the following steps are included:

[0049] S1. When the distance or height between the hydroponic box 6 in the middle of the bottom bar 4 and the top frame 5 needs to be adjusted, just hold the pinching blocks 74 at both ends of the hydroponic box 6 with both hands at the same time, and then move up and down between the bottom bar 4 and the middle of the top frame 5 to adjust the distance and height between the hydroponic box 6. When the height of the hydroponic box 6 in the middle of the bottom bar 4 and the top frame 5 is adjusted, just release the pinching blocks 74 to fix the height of the hydroponic box 6 in the middle of the bottom bar 4 and the top frame 5;

[0050] S2, when the Dalbergia odorifera germplasm preservation device is running, the water pump 13 finally delivers the water source to the hydroponic box 6 through the water inlet pipe 14 for use. When there is too much water in the hydroponic box 6 to submerge the cultivated seedlings, the excess water flows back into the water storage tank 11 through the overflow pipe plug 62 for recycling;

[0051] S3. When the required hydroponic boxes 6 are not enough and it is necessary to add hydroponic boxes 6 vertically, the height can be increased by inserting the spiral plug 51 at the end of the top frame 5 into the spiral slot 41 at the top of the top frame 5 and rotating it. When it is necessary to add hydroponic boxes 6 horizontally, it can be lengthened by docking the mounting blocks 18 at both ends of a water storage tank 1 with the connecting sleeve 43 at the bottom of the adjacent bottom rod 4;

[0052] S4. When the Dalbergia odorifera germplasm preservation device needs to be completely disassembled, the disassembly can be completed quickly by simply using quick-plug connections between the components.

[0053] In this embodiment, when the Dalbergia odorifera germplasm preservation device is used and the spacing or height between the bottom rod 4 and the hydroponic box 6 in the middle of the top frame 5 needs to be adjusted, it is only necessary to hold the pinching blocks 74 at both ends of the hydroponic box 6 with both hands at the same time, and the palms of the hands are against the handle block 7. The pinching of the two ends of the pinching block 74 will drive the driving rod 75 to move toward the handle block 7, and the end of the driving rod 75 away from the pinching block 74 will drive the driving block 76 to move, and the driving block 76 drives the inserting block 77 to insert into the sliding slot 81. When the end of the handle block 7 away from the driving block 76 is against the anti-slip block 83, the anti-slip block 83 can drive the sliding protrusion 82 to retract into the sliding slot 81. At the same time, the spacing and height between the hydroponic boxes 6 can be adjusted by moving up and down between the bottom rod 4 and the middle of the top frame 5. When the height of the hydroponic box 6 is adjusted in the middle of the bottom rod 4 and the top frame 5, it is only necessary to loosen the pinching block 74. At this time, the pinching block 74 can slide along the support rod 71 to abut against the clamping head 72 through the elastic thrust of the push spring 73 on the support rod 71, so that the pair of driving rods 75 can drive the plug block 77 to disengage from the sliding slot 81 in turn. At this time, the anti-slip block 83 that is not abutted will drive the sliding protruding rod 82 to move toward the U-shaped groove through the elastic thrust of the reset spring 84, and finally the end of the sliding protruding rod 82 away from the anti-slip block 83 can be inserted into the corresponding mounting hole 451 on the bottom rod 4 or the top frame 5, so that the height of the hydroponic box 6 in the middle of the bottom rod 4 and the top frame 5 can be fixed;

[0054] When the Dalbergia odorifera germplasm preservation device is in operation, the water pump 13 in the installation tank 12 is started, and the water pump 13 transports the water in the water storage tank 11 to the water receiving sleeve 2 through the water inlet pipe 14 and the L-shaped water pumping pipe 16 through the water outlet pipe 15, and then transports it to the multiple first corrugated hoses 22 through the first transverse pipe 21 on the water receiving sleeve 2, and then transports the water source to the hydroponic box 6 for use through the first sleeve 23 at the top of the first corrugated hose 22 and the installation pipe plug 61. When there is too much water in the hydroponic box 6 to submerge the cultivated seedlings, the overflow pipe plug 62 is set so that the excess water will flow through the corresponding second sleeve 33, the second corrugated hose 32, the second transverse pipe 31, and the water delivery sleeve 3 in sequence, and finally flow back into the water storage tank 11 for recycling by gravity. When the required hydroponic box 6 is not enough and it is necessary to increase the hydroponic box 6 vertically, it is only necessary to insert the spiral plug 51 at the end of the top frame 5 into the spiral slot 41 at the top of the top frame 5 and rotate it to complete the heightening. When it is necessary to add a hydroponic box 6 laterally, it is only necessary to connect the mounting blocks 18 at both ends of a water storage tank 1 to the connecting sleeve 43 at the bottom of the bottom rod 4 on the adjacent side, and finally Figure 2 Just increase the height, simple and easy to operate.

[0055] When it is necessary to completely disassemble the Dalbergia odorifera germplasm preservation device, it is only necessary to first insert the multiple second sleeves 33 into the installation pipe plug 61 and pull them out, and then insert the multiple first sleeves 23 into the overflow pipe plug 62 and pull them out. Then, pull out the bottom end of the water supply sleeve 3 from the top of the connection port 19, and then pull out the bottom end of the water receiving sleeve 2 from the water outlet pipe 15 on the water pump 13. Then, the hydroponic box 6 is completely taken out from the middle of the bottom rod 4 and the top frame 5, and then the top frame 5 is rotated to drive the spiral plug 51 to rotate. Since the spiral plug 51 is spirally connected to the spiral slot 41 at the top of the bottom rod 4, the top frame 5 can be made to fall off from the top of the bottom rod 4. The above operation can be repeated for multiple connected bottom rods 4 and top frames 5, and the connection is not repeated here. Finally, the connecting sleeve 43 at the bottom of the bottom rod 4 is removed from the mounting blocks 18 at both ends of the hydroponic box 6 to complete the disassembly.
