Description

Technical Field

[0001] The invention relates to the technical field of corn cultivation, in particular to a cultivation device for corn seed breeding. Background Art

[0002] Corn is an annual monoecious, cross-pollinated plant with tall plants and strong stems. It is an important food crop and feed crop with great potential for developing high-nutrition, high-biological-functional foods. It is also one of the crops with the highest total output in the world. Corn has strong drought resistance, cold resistance, and resistance to poor soil conditions, as well as excellent environmental adaptability. As one of China's major food crops, corn is an important source of feed for animal husbandry, breeding, aquaculture, etc., and is also one of the indispensable raw materials for food, medical and health care, light industry, chemical industry, etc.

[0003] The quality of corn seed breeding technology is a key factor in corn yield. To cultivate corn seeds, corresponding breeding equipment is needed to allow the seeds to germinate first and then plant them in the soil. Due to its complex genetics and rich variety of variations, existing breeding technologies often use a combination of physical environmental changes and chemical mutagenesis to achieve mutagenesis breeding of corn seeds. However, in the process of corn seed breeding, traditional breeding methods are greatly disturbed by the natural environment and have low breeding efficiency. Existing waterless breeding equipment has problems with insufficient synergy in seed positioning, environmental control, and nutrient supply. This may affect the cultivation of corn seedlings, and once unqualified seedlings are selected for planting, it will affect the production quality of corn and cause great losses to the economy. Summary of the Invention

[0004] The present invention aims to provide a cultivation device for corn seed breeding, comprising: a screening assembly for screening and collecting corn seeds during breeding; a water storage tank fixedly mounted on the outer surface of the screening assembly; a cover plate rotatably mounted on the top of the water storage tank; and an injection port fixedly mounted on the top of the cover plate; A diversion support assembly, which is used to stably support the cultivation components and circulate the culture fluid. The outer surface of the diversion support assembly is fixedly connected to the screening assembly and the water storage tank, and one side of the outer surface of the diversion support assembly extends through the water storage tank to the interior of the water storage tank; The cultivation assembly is used for corn seed screening and soilless seed cultivation. The cultivation assembly is fixedly installed inside the diversion support assembly and is compatible with the diversion support assembly. When using this cultivation assembly for breeding, the impact of seed size on the breeding results must be considered first. Larger seeds generally store more nutrients and can provide more energy to support germination and initial growth when water is scarce. Smaller seeds, on the other hand, may have insufficient nutritional reserves and, even if they have good drought-resistant genes, may find it difficult to show advantages in waterless cultivation and are easily misjudged. When selecting and breeding corn seeds, the staff first put the corn seeds into the cultivation component. At this time, the smaller corn seeds are screened out from the cultivation component and fall into the diversion support component. By pre-screening the seed size, the interference of nutritional reserve differences on the waterless cultivation results can be eliminated, so that different seeds can be tested on a relatively fair basis. Then the staff injects the prepared culture solution into the water storage tank through the injection port. The culture solution flows into the diversion support component layer by layer, and the seeds that fall into the diversion support component are screened out. As the culture solution flows, the seeds screened out are transported to the screening component to separate the seeds from the culture solution, and the culture solution is recovered into the water storage tank to improve the fluidity of the culture solution and provide trace and balanced nutrition for the seeds.

[0005] Preferably, the diversion support assembly includes a support frame, and the support frames are provided with two, and the bottoms of the two support frames are fixedly mounted with a base frame, and a reinforcement plate is fixedly mounted between the opposite surfaces of the base frames, and an inlet pipe is fixedly mounted on one side of the top of the base frame, and a connecting pipe is fixedly mounted on the outer surface of the inlet pipe, and a circulation guide frame is provided on the outer surface of the inlet pipe, and the circulation guide frame is provided with a three-layer structure, and an extension pipe is provided on the surface of the circulation guide frame close to the base frame, and a valve is rotatably mounted on the top of the extension pipe, and the circulation guide frame is fixedly mounted inside the support frame. After the staff puts the corn seeds into the cultivation assembly, the staff rotates the valve on the side of the inlet pipe to allow the culture solution to flow into the circulation guide frame along the inlet pipe. The circulation guide frame is provided with a multi-layer structure, and the multi-layer circulation guide frames are staggered in a stepped manner. The culture solution flows layer by layer along the circulation guide frame, and the flowing culture solution can drive the nutrients to be evenly distributed.

[0006] Preferably, the inlet pipe passes through the water tank and extends to the interior of the cavity thereof. Two extension pipes are provided, and the two extension pipes are fixedly connected to the water tank and the screening assembly respectively.

The curved pipes installed on the outside of the frame pipes are connected to the upper layer through vertical pipes so that the culture solution can flow into the frame pipes on the upper layer. When the nutrient solution flows in the pipe, it drives the seeds screened out of the frame pipes to flow into the screening assembly, so that the culture solution flows to the water storage tank for recycling. The circulating culture solution can provide trace and balanced nutrition to the seeds through slow osmosis, and at the same time, the flow characteristics are used to avoid local water accumulation and prevent excessive water from interfering with seed growth.

A limiting groove is provided on the inner wall of the cultivation box, and a floating planting piece is slidably installed inside the limiting groove. The staff puts seeds into the floating planting piece in the cultivation box, and the smaller seeds are screened out from the bottom of the floating planting piece and fall into the frame pipe. The culture fluid flows in the frame pipe and transports the screened seeds to the screening component. Screening seeds of uniform size for waterless cultivation can make the growth stages of seeds in the same environment more synchronized, facilitate standardized observation, reduce data errors, and improve the utilization efficiency of equipment space and experimental resources.

The culture solution is transported to the inner pipe, and at this time the culture solution overflows into the rack pipe along the water guide groove opened on the surface of the inner pipe. As the water level in the rack pipe continues to rise, the floating plate drives the slider to slide upward in the limiting groove, so as to facilitate the observation of the germination state of the seeds during the waterless cultivation of corn. The floating plate is set as a food-grade plastic hard plate, and the surface is designed with uniform square grooves at fixed intervals. The cultivation trough installed in the square groove can accurately place single corn seeds, so that the embryo of each seed is at the same height and position, ensuring that the environmental conditions exposed to the seeds in the waterless cultivation matrix are consistent, avoiding local microenvironmental differences caused by the messy placement of seeds, and achieving the purpose of reducing experimental errors and more accurately reflecting seed cultivation data.

The sieve holes provided on the surface of the screening plate filter the seeds into the collection cavity to collect the screened seeds, thereby preventing the seeds from accumulating in the rack pipe and affecting seed cultivation. At the same time, the screening plate separates the culture fluid from the seeds to facilitate the recycling of the culture fluid.

[0013] Preferably, the sleeve plate is threadedly mounted on the inner wall of the water tank, the discharge pipe passes through the water tank and extends to the interior of the cavity thereof, and one end of the discharge pipe away from the water tank is fixedly connected to the extension pipe.

The curved arc tubes installed on the outside of the rack tubes are connected to the upper layer through vertical pipes so that the culture fluid can flow into the rack tubes on the upper layer. When the nutrient solution flows in the pipe, it drives the seeds screened out of the rack tubes to flow into the screening assembly, so that the culture fluid flows into the water storage tank for recycling. The circulating culture fluid can provide the seeds with trace and balanced nutrition through slow osmosis, and at the same time utilizes the flow characteristics to avoid local water accumulation and prevent excessive water from interfering with seed growth.

[0015] 2. The cultivation equipment used for corn seed selection and breeding is that the staff puts the seeds into the floating planting pieces in the cultivation box. The smaller seeds are screened out from the bottom of the floating planting pieces and fall into the frame pipe. The culture fluid flows in the frame pipe to transport the screened seeds to the screening component.

At this time, the culture medium overflows into the rack tube along the water guide groove opened on the surface of the inner tube. As the water level in the rack tube continues to rise, the floating plate drives the slider to slide upward in the limit groove, so as to facilitate observation of the germination state of the seeds during the waterless cultivation of corn. The floating plate is set to a food-grade plastic hard plate, and the surface is designed with uniform square grooves at fixed intervals. The cultivation grooves installed in the square grooves can accurately place single corn seeds, so that the embryo of each seed is at the same height and position, ensuring that the environmental conditions exposed to the seeds in the waterless cultivation matrix are consistent, avoiding local microenvironmental differences caused by the messy placement of seeds, thereby reducing experimental errors and more accurately reflecting the seed cultivation data.

[0017] 4. The cultivation equipment for corn seed selection and breeding is that the seeds sieved from the bottom of the sieve hole fall into the inside of the rack tube. When the culture fluid flows in the rack tube, the sieved seeds are driven out of the rack tube and transported to the screening plate along the discharge pipe. The sieve holes opened on the surface of the screening plate sieve the seeds into the collection cavity to collect the sieved seeds, thereby preventing the seeds from accumulating in the rack tube and affecting the seed cultivation. At the same time, the screening plate separates the culture fluid and the seeds to facilitate the recycling of the culture fluid.

By pre-screening the seed size, the interference of nutritional reserve differences on the waterless cultivation results can be eliminated, so that different seeds can be tested on a relatively fair basis. Then the staff injects the prepared culture solution into the water storage tank through the injection port. The culture solution flows into the diversion support component layer by layer, and the seeds that fall into the diversion support component are screened out. The seeds screened out as the culture solution flows are transported to the screening component to separate the seeds from the culture solution, and the culture solution is recovered into the water storage tank to improve the fluidity of the culture solution and provide trace and balanced nutrition for the seeds.

A discharge pipe 63 is fixedly mounted on the outer surface of the screening plate 62. Seeds sieved from the bottom of the sieve holes 537 fall into the interior of the rack pipe 312. When the culture medium flows through the rack pipe 312, the sieved seeds are drawn from the rack pipe 312 and transported along the discharge pipe 63 into the screening plate 62. The sieve holes 66 defined on the surface of the screening plate 62 filter the seeds into the collection chamber 64, thereby collecting the sieved seeds and preventing them from accumulating in the rack pipe 312 and affecting seed cultivation. The screening plate 62 also separates the culture medium from the seeds for recycling.

[0023] The sleeve plate 61 is threadedly mounted on the inner wall of the water tank 2 , and the discharge pipe 63 penetrates the water tank 2 and extends into the interior of the cavity thereof. One end of the discharge pipe 63 away from the water tank 2 is fixedly connected to the extension pipe 33 .

[0024] The diversion support assembly 3 is used to stably support the cultivation components and circulate the culture solution. The outer surface of the diversion support assembly 3 is fixedly connected to the screening assembly 6 and the water storage tank 2 respectively. One side of the outer surface of the diversion support assembly 3 passes through the water storage tank 2 and extends into the interior of the cavity thereof; The cultivation component 5 is used for corn seed screening and soilless seed cultivation. The cultivation component 5 is fixedly installed inside the diversion support component 3, and the cultivation component 5 is adapted to be installed with the diversion support component 3.

[0025] The second embodiment, based on the first embodiment, see Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 8As shown, the diverter support assembly 3 includes a support frame 32, and there are two support frames 32. A base frame 34 is fixedly installed at the bottom of the two support frames 32, and a reinforcement plate 35 is fixedly installed between the opposite surfaces of the base frame 34. An inlet pipe 37 is fixedly installed on one side of the top of the base frame 34, and a connecting pipe 38 is fixedly installed on the outer surface of the inlet pipe 37. A circulation diverter frame 31 is provided on the outer surface of the inlet pipe 37. The circulation diverter frame 31 is set as a three-layer structure. The surface of the circulation diverter frame 31 close to the base frame 34 is provided with an extension pipe 33. A valve 36 is rotatably installed on the top of the extension pipe 33. The circulation diverter frame 31 is fixedly installed inside the support frame 32. After the staff puts the corn seeds into the cultivation component 5, the staff turns the valve 36 on the side of the inlet pipe 37 to allow the culture solution to flow into the circulation guide frame 31 along the inlet pipe 37. The circulation guide frame 31 is configured as a multi-layer structure, and the multi-layer circulation guide frame 31 is staggered in a stepped manner. The culture solution flows along the circulation guide frame 31 layer by layer, and the flowing culture solution can drive the uniform distribution of nutrients.

[0026] The inlet pipe 37 passes through the water tank 2 and extends to the interior of the cavity thereof. Two extension pipes 33 are provided, and the two extension pipes 33 are fixedly connected to the water tank 2 and the screening assembly 6 respectively.

[0027] The circulation guide frame 31 includes a frame pipe 312, a mounting groove 311 is opened on the top of the frame pipe 312, sleeve pipes 316 are sleeved on both sides of the outer surface of the frame pipe 312, a curved arc pipe 313 is fixedly installed on the outer surface of the sleeve pipe 316, a positioning pipe 315 is fixedly installed on the outer surface of the curved arc pipe 313, and a vertical pipe 314 is fixedly installed inside the positioning pipe 315. The culture solution is transported to the rack tube 312 along the inlet pipe 37. The rack tube 312 is configured as a one-way flow channel. The curved arc tube 313 installed on the outside of the rack tube 312 is connected to the upper layer through the vertical pipe 314, so that the culture solution can flow into the upper rack tube 312. When the nutrient solution flows in the pipeline, it drives the seeds screened out of the rack tube 312 to flow into the screening component 6, so that the culture solution flows into the water storage tank 2 for recycling. The circulating culture solution can provide trace and balanced nutrition to the seeds through slow osmosis, and at the same time utilizes the flow characteristics to avoid local water accumulation and prevent excessive water from interfering with seed growth.

[0028] The frame pipe 312 is sleeved on the outer surface of the cultivation component 5. The frame pipe 312 is staggeredly installed through the curved arc pipe 313 and the vertical pipe 314. The frame pipe 312 is fixedly installed inside the support frame 32. The surface of the frame pipe 312 close to the base frame 34 is fixedly connected to the extension pipe 33.

[0029] The third embodiment, based on the first and second embodiments, see Figures 9 to 14As shown, the cultivation assembly 5 includes an internal pipe 51, which is fixedly mounted inside the frame pipe 312. A water channel 54 is defined at the top of the internal pipe 51 and is disposed opposite the mounting slot 311. A cultivation box 52 is fixedly mounted outside the water channel 54. The cultivation box 52 extends through the mounting slot 311 and outward therefrom. A limiting groove 55 is defined on the inner wall of the cultivation box 52, and a floating planting member 53 is slidably mounted inside the limiting groove 55. When a worker places seeds into the floating planting member 53 within the cultivation box 52, smaller seeds are screened out from the bottom of the floating planting member 53 and fall into the frame pipe 312. The culture fluid flows within the frame pipe 312, transporting the screened seeds to the screening assembly 6. Screening seeds of uniform size for waterless cultivation allows for more synchronized growth stages of seeds under the same environment, facilitates standardized observation, reduces data errors, and improves the utilization efficiency of equipment space and experimental resources.

[0030] The floating planting member 53 includes a floating plate 532, a slider 533 is fixedly installed on the outer surface of the floating plate 532, a square groove 534 is opened on the surface of the floating plate 532, a positioning ring 531 is fixedly installed on the top of the square groove 534, a cultivation groove 535 is fixedly installed on the bottom of the positioning ring 531, a filter hole 536 is opened on the outer surface of the cultivation groove 535, and a screening hole 537 is opened in the middle of the bottom of the cultivation groove 535.

[0031] The cultivation trough 535 is fixed within the square groove 534, the slider 533 is slidably mounted within the limiting groove 55, and the floating plate 532 is movably mounted within the cultivation box 52 via the slider 533. When the culture medium is delivered to the internal pipe 51, it overflows into the frame pipe 312 along the water guide groove 54 provided on the surface of the internal pipe 51. As the water level in the frame pipe 312 continues to rise, the floating plate 532 drives the slider 533 to slide upward within the limiting groove 55, facilitating observation of the germination status of corn seeds during waterless cultivation. The floating plate 532 is constructed of a hard, food-grade plastic sheet with uniformly spaced square grooves 534 on its surface. The cultivation troughs 535 mounted within the square grooves 534 precisely position individual corn seeds, ensuring that the embryo of each seed is at the same height and position. This ensures that the seeds are exposed to consistent environmental conditions within the waterless cultivation medium, avoids local microenvironmental variations caused by disorganized seed placement, and thus reduces experimental errors and more accurately reflects seed cultivation data.

[0032] When using the cultivation component for breeding, the effect of seed size on the breeding results must be considered first. Since larger seeds usually store more nutrients, they can provide more energy to support germination and initial growth when water is scarce. However, smaller seeds may have insufficient nutritional reserves. Even if they have good drought-resistant genes, they are difficult to show advantages in waterless cultivation and are easily misjudged. When breeding corn seeds, the staff first put the corn seeds into the cultivation component 5. At this time, the smaller corn seeds are screened out from the cultivation component 5 and fall into the diversion support component 3. By pre-screening the seed size, the interference of nutritional reserve differences on the waterless cultivation results can be eliminated, so that different seeds can be tested on a relatively fair basis. Then the staff injects the prepared culture solution into the water storage tank 2 through the injection port 4. The culture solution flows into the diversion support component 3 layer by layer, and the seeds that fall into the diversion support component 3 are screened out. The seeds screened out as the culture solution flows are transported to the screening component 6 to separate the seeds from the culture solution, and the culture solution is recovered into the water storage tank 2 to improve the fluidity of the culture solution and provide the seeds with trace and balanced nutrition.
