Description

Technical Field

[0001] This invention relates to the field of seed cultivation technology, and more specifically, to a seed cultivation device and method for improving germination rate. Background Technology

[0002] Seeds are the reproductive bodies unique to gymnosperms and angiosperms, formed from ovules through pollination and fertilization. They generally consist of three parts: the seed coat, the embryo, and the endosperm. Seed formation allows the young sporophyte ovule to be protected by the parent plant and, like a mammalian fetus, to receive ample nutrients. Seeds also possess various structures adapted for dispersal or resistance to adverse conditions, creating favorable conditions for the continuation of the plant species. Seed germination refers to a series of ordered physiological and morphological processes that begin with imbibition. Seed germination requires suitable temperature, adequate moisture, and sufficient air. During germination, the seed first absorbs water. Soaking in water causes the seed coat to swell and soften, allowing more oxygen to penetrate into the seed while carbon dioxide is released, resulting in changes in the internal physical state.

[0003] In existing technologies, improving the germination rate of seeds is crucial. Selecting superior varieties for planting can increase yield per unit area. Breeding superior new varieties is of paramount importance, especially for germinating old seeds that have been stored for a long time. Before seed cultivation, manual selection and drying of corn seeds are still required, which is time-consuming, labor-intensive, and inefficient, hindering the promotion of modern mechanized agriculture.

An upper insert rod is inserted into the top of a lower fixed rod, and a rotary sieving device is fixedly connected to the surface of the upper insert rod. When the output shaft of the synchronous motor of the vertical rod assembly and the rotary sieving device rotates, the seeds located inside the soaking device rotate with the water. Shriveled seeds detach from the plump seeds and float to the surface, thus screening for seed quality and retaining plump, high-quality seeds, thereby improving the seed germination rate and solving the problems mentioned in the background art.

A stirring side baffle is fixedly installed on one side of the fan-shaped folding plate.

[0006] In a preferred embodiment, the vertical rod assembly includes a lower fixing rod, into which an upper insert rod is inserted.

[0007] In a preferred embodiment, the soaking device includes a lifting groove with multiple sets of liquid guiding holes penetrating its surface. The lifting groove has three sets of L-shaped grooves inside, which are distributed in a ring at equal intervals. Each set of L-shaped grooves has two sets of positioning rods vertically inserted inside. An extension positioning plate is fixedly connected to the surface of the positioning rod, and the extension positioning plate extends through the L-shaped groove toward the vertical rod assembly. The fan-shaped folding plate is fan-shaped, and the center angle of the fan-shaped folding plate is 135 degrees.

[0008] In a preferred embodiment, the photo-induced device includes an end clip that engages with the top of the liquid storage tank. The end clip is fixedly connected to an annular bonding plate at the bottom of the inner cavity of the liquid storage tank. The annular bonding plate has a telescopic sliding cavity inside and a plurality of circular insertion holes at the bottom of the annular bonding plate.

[0009] In a preferred embodiment, three sets of fan-shaped telescopic plates are slidably installed inside the telescopic cavity. An internal rotating rod is rotatably installed inside the top of the fan-shaped telescopic plate. A telescopic rectangular plate is rotatably installed on the surface of the internal rotating rod. A fan-shaped sealing plate is rotatably installed at the top of the telescopic rectangular plate.

[0010] In a preferred embodiment, a semi-sunken groove is formed on the opposite end face of the sector-shaped sealing plate and the sector-shaped telescopic plate, and the depth of the semi-sunken groove is greater than the thickness of the telescopic rectangular plate.

[0011] In a preferred embodiment, a certain gap is left between the soaking device and the storage tank, and four sets of ultraviolet lamps are fixedly installed at the bottom of the end clip, with the four sets of ultraviolet lamps located inside the gap between the soaking device and the storage tank.

[0012] In a preferred embodiment, four sets of vertical abutments are vertically inserted inside the liquid storage tank, the soaking device is mounted on the top of the four sets of vertical abutments, and an annular sealing ring is fitted at the connection between the vertical rod assembly and the liquid storage tank.

[0013] In a preferred embodiment, the magnetic induction device includes an annular threaded end and a fixed concealed box. The fixed concealed box is a box-shaped structure with its opening facing upwards. A spiral magnetic coil is installed inside the fixed concealed box, and the top end of the spiral magnetic coil is slidably mounted inside the annular threaded end.

[0014] In a preferred embodiment, a seed cultivation method for improving germination rate includes the following steps: S1: Vertically insert the soaking device into the inner cavity of the storage tank, so that the lower fixing rod passes through the bottom center of the soaking device. The four sets of vertical abutting rods are in abutting state with the soaking device. The inner cavity of the soaking device is filled with seeds. Vertically insert the upper rod together with the rotary sieving device into the top of the upper rod. At the same time, insert the photo-inducing device into the top of the storage tank, turn on the ultraviolet lamp, and the seeds are irradiated with ultraviolet light for 6-10 hours. S2: The inside of the storage tank is filled with soaking solution. The seeds obtained in step one are soaked in the soaking solution. The motor is turned on to make the soaking solution rotate, thereby screening the quality of the seeds. After the fan-shaped folding plate collects the inferior seeds, the upper rod and the rotating screening device are taken out of the soaking solution by holding the end of the upper rod. S3: Combine the three sets of fan-shaped sealing plates and the three sets of fan-shaped telescopic plates inward, so that the three sets of fan-shaped sealing plates abut against each other, and the top of the soaking device is in a sealed state.

[0015] The technical effects and advantages of this invention are as follows: 1. The present invention has an upper insert rod inserted at the top of the lower fixed rod, and a rotary screening device is fixedly connected to the surface of the upper insert rod. When the output shaft of the synchronous motor of the vertical rod assembly and the rotary screening device rotates, the seeds located in the inner cavity of the soaking device rotate with the water. The shriveled seeds are released from the plump seeds and float to the surface, which is used to screen the quality of seeds, retain the plump high-quality seeds, and improve the seed germination rate. 2. This invention utilizes the rotation of water to induce friction between numerous seeds, causing wear on the seed coat and thus improving the germination rate. 3. This invention uses the rotation of water to cause numerous seeds to have inertia. When the rotating sieving device stops rotating, inferior seeds automatically flow into the space formed by the fan-shaped folding plate and the stirring side baffle, thereby collecting shriveled and poor-quality seeds without the need for manual collection.

[0016] 4. This invention stimulates seed vigor through soaking, damaging the seed coat, ultraviolet irradiation, and magnetic field induction, which is more beneficial for the germination of seeds stored for a long time. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Refer to the instruction manual appendix Figure 1-8 An embodiment of the present invention provides a seed cultivation device for improving germination rate, comprising a storage tank 1, an immersion device 2 disposed inside the storage tank 1, a magnetic induction device 3 attached to the outer surface of the storage tank 1, and a light induction device 4 engaged at the top of the storage tank 1. Figure 1-5 As shown, the storage tank 1 and the soaking device 2 are arranged in a cavity shape with the opening facing upward. A motor 5 is fixedly installed at the bottom of the storage tank 1. A lead screw is fixedly connected to the end of the output shaft of the motor 5. A vertical rod assembly 7 is fixedly connected to one end of the lead screw that passes through the bottom of the storage tank 1. The vertical rod assembly 7 is rotatably installed inside the soaking device 2. A rotary sieving device 8 is fixedly installed on the surface of the vertical rod assembly 7 within the inner cavity of the soaking device 2. The rotary sieving device 8 includes a lug-type fixing ring 801 fixedly connected to the surface of the vertical rod assembly 7. A set of circular rings 802 passes through the inside of the lug-type fixing ring 801. A fan-shaped folding plate 803 is rotatably connected to the surface of the circular rings 802. The cross-section of the fan-shaped folding plate 803 is V-shaped. Multiple sets of tightly spaced sieve holes 804 pass through the surface of the fan-shaped folding plate 803. A stirring side baffle 805 is fixedly installed on one side of the fan-shaped folding plate 803.

[0028] In the specific implementation plan, the motor 5 is model Y80M1-2. Four sets of table legs are fixedly connected to the bottom of the storage tank 1 and the periphery of the motor 5. The four sets of table legs are mainly used to support the cultivation device and are located in a certain installation space of the motor 5. The soaking device 2 is filled with a certain amount of seeds. Due to their own quality, the plump seeds will settle at the bottom of the soaking device 2, while the shriveled and poor-quality seeds will float to the surface, thus screening the seed quality. However, when a large number of seeds are put in for screening at one time, the shriveled seeds are mixed among the many seeds and cannot float due to their own buoyancy, resulting in poor seed screening results.

[0029] A set of switches is installed on the surface of the liquid storage tank 1. The switches are electrically connected to the motor 5 and are used to control the rotation of the motor 5. The motor 5 acts as a drive source. When the motor 5 is turned on and rotates forward, the output shaft screw of the motor 5 drives the vertical rod assembly 7 to rotate synchronously, thereby controlling the synchronous rotation of the lug-type fixing ring 801, the circular ring 802, the fan-shaped folding plate 803, and the stirring side baffle 805. (Refer to...) Figure 3At this time, the ear-fixed ring 801, circular ring 802, fan-shaped folding plate 803, and stirring side baffle 805 rotate clockwise around the vertical center of the vertical rod assembly 7. The fan-shaped folding plate 803 and stirring side baffle 805 impact the water surface, causing the seeds located in the inner cavity of the soaking device 2 to rotate with the water. The friction between the numerous seeds wears down the seed coat, improving the germination rate. Secondly, during the rotation, the shriveled seeds detach from the plump seeds and float to the surface. At this time, the motor 5 is turned off, and the ear-fixed ring 801, circular ring 802, fan-shaped folding plate 803, and stirring side baffle 805 stop rotating. The shriveled seeds follow the water flow into the space formed by the fan-shaped folding plate 803 and stirring side baffle 805, thus collecting the shriveled and poor-quality seeds without manual collection.

[0030] Furthermore, such as Figure 5 As shown, the vertical rod assembly 7 includes a lower fixing rod 701, and an upper insert rod 702 is inserted inside the lower fixing rod 701.

[0031] The vertical rod assembly 7 is divided into a lower fixed rod 701 and an upper insert rod 702. The upper insert rod 702 is vertically inserted into the lower fixed rod 701. The lower fixed rod 701 and the upper insert rod 702 rotate synchronously. After the rotary screening device 8, which is fixedly connected to the surface of the vertical rod assembly 7, has collected the shriveled seeds, the upper insert rod 702 and the rotary screening device 8 can be directly pulled out of the water by holding the top of the upper insert rod 702 together. There is no need to put your hand into the water, which would cause water pollution or contamination of your hands.

[0032] It should be noted that the water level is below the top of the circular ring 802 and below the top edge of the stirring side baffle 805, but above the upper surface of the fan-shaped folding plate 803. At the same time, the sieve holes 804 on the surface of the fan-shaped folding plate 803 are used to filter out the water when the rotary screening device 8 is moved upward.

[0033] Example 2: Further, such as Figure 3 As shown, the soaking device 2 includes a lifting groove 201. Multiple sets of liquid guiding holes 202 penetrate the surface of the lifting groove 201. Three sets of L-shaped grooves 203 are opened inside the lifting groove 201. The three sets of L-shaped grooves 203 are distributed in a ring at equal intervals inside the lifting groove 201. Two sets of positioning rods 204 are vertically inserted inside each set of L-shaped grooves 203. An extension positioning plate 205 is fixedly connected to the surface of the positioning rod 204. The extension positioning plate 205 extends through the L-shaped groove 203 toward the vertical rod assembly 7. like Figure 8 As shown, the fan-shaped folding plate 803 is arranged in a fan shape, and the center angle of the fan-shaped folding plate 803 is 135°.

[0034] A positioning rod 204 is inserted inside the lifting groove 201, and an extension positioning plate 205 is provided on the surface of the positioning rod 204. The extension positioning plate 205 can serve as a water surface marker line for adding appropriate liquid into the inner cavity of the storage tank 1 and the soaking device 2. Secondly, a fan-shaped folding plate 803 is rotatably mounted on the surface of the circular ring 802. The fan-shaped folding plate 803 is in contact with the extension positioning plate 205 during rotation. The extension positioning plate 205 serves as a support for the fan-shaped folding plate 803. The angle between two adjacent sets of extension positioning plates 205 is less than 120°, which ensures that the fan-shaped folding plate 803 is always in contact with one set of extension positioning plates 205 during rotation.

[0035] Furthermore, such as Figure 4 As shown, the photo-induced device 4 includes an end clip 401 that engages with the top of the liquid storage tank 1. The end clip 401 is fixedly connected to an annular bonding plate 402 at the bottom of the inner cavity of the liquid storage tank 1. The annular bonding plate 402 has a telescopic sliding cavity 403 inside and a plurality of circular insertion holes 404 at the bottom of the annular bonding plate 402.

[0036] Multiple circular insertion holes 404 are arranged in a one-to-one correspondence with multiple positioning rods 204. When the photo-induced device 4 is engaged at the top of the liquid storage tank 1, its multiple positioning rods 204 are inserted into the interior of the multiple circular insertion holes 404.

[0037] The optical inducer 4 is attached to the top of the liquid storage tank 1, and the optical inducer 4 is used to fix the position of the positioning rod 204 and the extension positioning plate 205.

[0038] Example 3: Further, such as Figure 7 As shown, three sets of sector-shaped telescopic plates 406 are slidably installed inside the telescopic cavity 403. An internal rotating rod 407 is rotatably installed inside the top of the sector-shaped telescopic plate 406. A telescopic rectangular plate 408 is rotatably installed on the surface of the internal rotating rod 407. A sector-shaped sealing plate 409 is rotatably installed at the top of the telescopic rectangular plate 408.

[0039] Furthermore, such as Figure 7 As shown, a semi-sunken groove is provided on the opposite end face of the sector-shaped sealing plate 409 and the sector-shaped telescopic plate 406. The depth of the semi-sunken groove is greater than the thickness of the telescopic rectangular plate 408.

[0040] The three sets of fan-shaped sealing plates 409 are brought inward to a horizontal position, and then the three sets of fan-shaped telescopic plates 406 are brought together toward the vertical center of the light-inducing device 4, thereby causing the three sets of fan-shaped sealing plates 409 to abut against each other. The three sets of fan-shaped telescopic plates 406 and the three sets of fan-shaped sealing plates 409 are used to seal the top of the soaking device 2, so that the seeds have a certain warming effect during the soaking process.

[0041] Furthermore, such as Figure 7 As shown, there is a certain gap between the soaking device 2 and the storage tank 1. Four sets of ultraviolet lamps 405 are fixedly installed at the bottom of the end clip 401. The four sets of ultraviolet lamps 405 are located inside the gap between the soaking device 2 and the storage tank 1.

[0042] Furthermore, such as Figure 2 As shown, four sets of vertical rods 9 are vertically inserted inside the storage tank 1. The soaking device 2 is mounted on the top of the four sets of vertical rods 9. An annular sealing ring 6 is attached to the connection between the vertical rod assembly 7 and the storage tank 1. The annular sealing ring 6 is used to seal and prevent water from seeping out of the inner cavity of the storage tank 1.

[0043] The vertical support rod 9 is used to support the soaking device 2, so that there is a certain vertical gap between the soaking device 2 and the storage tank 1. The bottom of the inner cavity of the storage tank 1 is used to retain a portion of the impurity particles left by the numerous seeds.

[0044] Furthermore, such as Figure 6 As shown, the magnetic induction device 3 includes an annular threaded end 301 and a fixed concealed box 303. The fixed concealed box 303 is a box-shaped structure with its opening facing upwards. A vortex magnetic coil 302 is installed inside the fixed concealed box 303, and the top end of the vortex magnetic coil 302 is slidably installed inside the annular threaded end 301.

[0045] The fixed concealed box 303 is fixedly installed on the outer surface of the liquid storage tank 1, and the annular threaded end 301 is threadedly connected to the outer wall of the liquid storage tank 1. A button is provided on the surface of the fixed concealed box 303, which is used to control the energization of the vortex magnetic coil 302.

[0046] Furthermore, a seed cultivation method for improving germination rate includes the following steps: S1: The soaking device 2 is vertically inserted into the inner cavity of the storage tank 1, causing the lower fixing rod 701 to pass through the bottom center of the soaking device 2. The four sets of vertical abutting rods 9 are in abutting state with the soaking device 2. The inner cavity of the soaking device 2 is filled with seeds. The upper insertion rod 702, together with the rotating sieve device 8, is vertically inserted into the top of the upper insertion rod 702. At the same time, the photo-inducing device 4 is inserted into the top of the storage tank 1. The ultraviolet lamp tube 405 is turned on, and the seeds are irradiated with ultraviolet light for 6-10 hours. S2: The inside of the storage tank 1 is filled with soaking solution. The seeds obtained in step one are soaked in the soaking solution. The motor 5 is turned on to make the soaking solution rotate, and then the quality of the seeds is screened. After the fan-shaped folding plate 803 collects the inferior seeds, the upper insertion rod 702 and the rotating screening device 8 are taken out from the soaking solution by holding the end of the upper insertion rod 702. S3: Combine the three sets of fan-shaped sealing plates 409 and the three sets of fan-shaped telescopic plates 406 inward, so that the three sets of fan-shaped sealing plates 409 abut against each other, and the top of the soaking device 2 is in a sealed state. Continue to soak the plump seeds from step two in the soaking solution for 3 days. The temperature of the soaking solution is 30℃. S4: After the soaking process is completed, the threaded end 301 of the stretched ring is screwed onto the outer surface of the liquid storage tank 1, the vortex magnetic coil 302 is vertically unfolded, and then the vortex magnetic coil 302 is energized to generate a certain magnetic field inside the vortex magnetic coil 302, thereby stimulating the germination rate of the seeds.

[0047] Seed vigor can be stimulated by soaking, damaging the seed coat, irradiating with ultraviolet light, and inducing germination with a magnetic field, which is especially beneficial for the germination of seeds that have been stored for a long time.
