[0029] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0030] like Figure 1 As shown, a breeding device includes a seedling environment simulation chamber 11, a seedling rack 13 is arranged inside the seedling environment simulation chamber 11, a plurality of transplanting racks 14 for planting rice seedlings are fixedly arranged on the seedling rack 13, a partition plate 15 is movably arranged inside the transplanting rack 14, and a plurality of seedling holes 16 are arranged in the partition plate 15. In normal rice under long-day conditions, the expression level of the gene can ensure the normal development of rice pollen and male fertility, while in photosensitive nuclear sterile rice, the base mutation in the pms3 gene region causes methylation modification in the promoter region of the gene itself, and the expression level decreases, which cannot meet the demand of rice pollen development for the expression product, thereby causing male sterility under long-day conditions. The fertility of the photosensitive nuclear sterile line is controlled by the nuclear gene and is affected by light conditions. This sterility changes with the length of daylight, that is, it manifests as male sterility under long-day conditions and restores fertility under short-day conditions. Therefore, in the selection and breeding of seeds based on the fertility mechanism of the two-line thermophotosensitive nuclear sterile line of Indica rice, it is necessary to simulate a more severe environment.

[0031] The side wall of the transplanting frame 14 is provided with a seedling supporting mechanism 2 for protecting the rice seedlings in the simulated wind and rain weather in the seedling raising environment simulation chamber 11, and the control end of the seedling supporting mechanism 2 is provided with an intelligent control mechanism 3;

[0032] like Figure 2 , Figure 4 and Figure 5 As shown, the seedling supporting mechanism 2 includes a retractable member, a control and support mechanism 4 and a seedling supporting arm 21. A soft plastic sheet 202 is provided on one side of the seedling supporting arm 21 close to the seedling planting hole 16. A plurality of mutually connected inflatable channels 204 are provided inside the soft plastic sheet 202. The retractable member is connected to the inflatable channels 204. The retractable member includes an air box 207. The air box 207 is squeezed to inflate the plurality of inflatable channels 204 and expand the soft plastic sheet 202. The control and support mechanism 4 is respectively connected to the seedling supporting arm 21 and the intelligent control mechanism 3. The control and support mechanism The structure 4 includes an arm control rope 22. When the seedling environment simulation room 11 simulates windy and rainy weather, the arm control rope 22 of the control and support mechanism 4 is controlled by the intelligent control mechanism 3 to simultaneously pull the seedling supporting arm 21 up, and during the raising process of the seedling supporting arm 21, the air channel 204 is inflated by the retractable component to expand the soft rubber sheet 202, which abuts against one side of the rice seedling bundle. In the seed selection and cultivation based on the fertility mechanism of the two-line thermophotosensitive nuclear sterile system of indica rice, the support of the soft rubber sheet 202 is more suitable for protecting rice seedlings in real environment simulation.

[0033] When simulating wind and rain, the seedling supporting arm 21 can rotate 90 degrees, driving the unfolded soft rubber sheet 202 to stick to one side of the rice seedlings like a palm, providing effective support for the rice seedlings, and can significantly enhance the stability of the rice seedlings in windy and rainy weather, and prevent the rice seedlings from tipping over due to wind or rain erosion. The soft rubber sheet 202 can reduce the friction between the rice seedlings and the transplanting rack 14, and reduce the risk of damage to the rice seedlings. For the two-line thermosensitive nuclear sterile rice seedlings of Indica, the breeding device can further study its fertility conversion characteristics and its relationship with environmental factors. The supporting effect of this design is more suitable for breeding based on the fertility mechanism of the two-line thermosensitive nuclear sterile Indica.

[0034] The material of the soft plastic sheet 202 is soft and durable, and can provide support for the rice seedlings while avoiding pressure or damage to the rice seedlings. This helps to maintain the healthy growth of the rice seedlings and reduce yield losses caused by mechanical damage. The rotation and unfolding of the seedling supporting arm 21 and the soft plastic sheet 202 are achieved through an automated control system, thereby improving the degree of automation in the breeding process.

[0035] like Figure 4 - Figure 7 As shown, a rotating drum 28 penetrating the side wall of the transplanting rack 14 is fixedly provided at one end of the seedling supporting arm 21 away from the soft plastic sheet 202, a torsion spring column 29 is provided inside the rotating drum 28, and the seedling supporting arm 21 is rotationally connected to the transplanting rack 14 through the rotating drum 28 and the torsion spring column 29, and the rotation range of the seedling supporting arm 21 is 0-90°.

[0036] The retracting and releasing component also includes a convex head 201 fixedly connected to the seedling supporting arm 21, a winding drum 205 is rotatably arranged inside the convex head 201, a force storage coil spring 206 is fixedly arranged inside the coil spring 205, a winding column 203 passing through the convex head 201 is fixedly arranged on the inner circle of the force storage coil spring 206, and the winding column 203 is fixedly connected to the soft plastic film 202, and a branch rope 25 passing through the convex head 201 is fixedly arranged in the coil spring 205.

[0037] The air box 207 is arranged inside the seedling supporting arm 21, and a magnetic block 208 is fixedly arranged at one end of the air box 207 close to the rotation center of the seedling supporting arm 21, and an impact weight 212 which is slidably connected to the seedling supporting arm 21 is arranged at the end of the air box 207 away from the rotation center of the seedling supporting arm 21, and a guide column 211 passes through the interior of the impact weight 212, and the guide column 211 also passes through the center line of the center of the air box 207, and a ventilation pipe 213 is connected to the air outlet end of the air box 207, and the end of the ventilation pipe 213 away from the air box 207 is interconnected with a plurality of inflation channels 204.

[0038] When the branch rope 25 is pulled by the control arm rope 22, the branch rope 25 will pass through the corresponding limit ring 24, so that the branch rope 25 is gradually released, and at the same time, the seedling supporting arm 21 is driven to rotate under the elastic force of the torsion spring column 29 and swing toward the rice seedlings. When the branch rope 25 is released, the stress of the power storage coil spring 206 drives the winding column 203 and the winding drum 1 205 to rotate, so that the relaxed branch rope 25 is wound up by the winding drum 1 205, so that the wound soft film 202 is released;

[0039] After the seedling supporting arm 21 is rotated, the convex head 201 is separated from the locking groove 26 provided on the transplanting frame 14, and the impact weight 212 loses the suction force of the magnetic block 27 in the locking groove 26, and the impact weight 212 is pulled down along the guide column 211 by the assisting rope 209 provided on the lower wall of the impact weight 212, and the air box 207 is squeezed, so that the air in the air box 207 is injected into the plurality of inflation channels 204 through the ventilation pipe 213, so that the soft rubber sheet 202 is unfolded after the seedling supporting arm 21 is rotated, until it is closely attached to one side of the rice seedling, so as to support the rice seedling and prevent the rice seedling from falling down when it rains, blows or the rice ear head is too heavy;

[0040] When the control arm rope 22 is pulled to reset by the rebound force of the reciprocating elastic rope 23, the seedling supporting arm 21 is pulled to reset again by the branch rope 25. At the same time, the branch rope 25 tightens the energy storage coil spring 206, and the soft film 202 is rewound by the winding column 203, and the air in the several inflation channels 204 flows back into the air box 207.

[0041] like Figure 2 , Figure 3 and Figure 8As shown, the control and support mechanism 4 also includes a protective cover 41 fixedly connected to the seedling rack 13, and a winding reel 45 is rotatably arranged inside the protective cover 41. A main control rope 43 is fixedly arranged in the winding reel 45, and a motor 42 is connected to the driving end of the winding reel 45.

[0042] A guide cylinder 44 is fixedly provided on the side wall of the seedling rack 13, and two branches of the total control rope 43 pass through the guide cylinder 44, and the two branches of the guide cylinder 44 are respectively connected to a plurality of control arm ropes 22 distributed along the side wall of the transplanting rack 14, and the plurality of control arm ropes 22 form a detachable structure with the two branches of the total control rope 43.

[0043] A reciprocating elastic rope 23 is fixedly provided at one end of the control arm rope 22 away from the main control rope 43, and the end of the reciprocating elastic rope 23 away from the control arm rope 22 is fixedly connected to the transplanting rack 14. A limiting ring 24 is fixedly provided on the side wall of the transplanting rack 14 corresponding to the position of the seedling supporting arm 21.

[0044] When simulating rain or wind, the motor 42 works, and the motor 42 drives the winding drum 2 45 to reel in the main control rope 43. As the main control rope 43 is reeled in, the branches of the main control rope 43 are gradually pulled, and the branches of the main control rope 43 simultaneously pull the control arm ropes 22 on both sides of the transplanting frame 14. The control arm ropes 22 are pulled to move along the plurality of limit rings 24 toward the end of the branches of the main control rope 43, and the two control arm ropes 22 are simultaneously pulled along the guide cylinder 44 following the branches of the main control rope 43, so that the two seedling supporting arms 21 can be controlled to rotate toward each other at the same time to clamp the rice seedlings in the middle;

[0045] Afterwards, when the simulated rain or wind stops, the motor 42 drives the second winding drum 45 to rotate in the opposite direction, slowly releasing the wound total control rope 43, and at the same time, the control arm rope 22 is pulled back to its original position by the resilience of the reciprocating elastic rope 23;

[0046] In addition, the staff can adjust the control arm rope 22 individually according to the direction of the simulated wind. The rotation direction of the seedling supporting arm 21 corresponding to each control arm rope 22 is different, and the rice seedlings can be supported on one side individually. The staff only needs to disconnect the corresponding control arm rope 22 to prevent the seedling supporting arm 21 from rotating, so that it is more flexible when simulating seasonal wind direction.

[0047] The staff can control the seedling supporting arm 21 to rotate according to the growth degree of the rice seedlings to clamp and support the higher and more vigorous rice seedlings to prevent the rice seedlings from falling over.

[0048] After the rice seedlings emerge, the staff can control the seedling supporting arm 21 and the soft plastic sheet 202 through the PCL controller 31 to pat the rice seedlings to increase their pollination rate. Because some rice seedlings bred based on the fertility mechanism of the two-line thermophotosensitive nuclear sterile line of indica rice are not easy to pollinate, patting them with external force is beneficial to increase their pollination rate.

[0049] The intelligent control mechanism 3 includes a PCL controller 31 , a sensor and a temperature control module which are arranged inside the seedling environment simulation chamber 11 .

[0050] The intelligent control mechanism 3 also includes a ceiling frame 32 fixed on the internal ceiling of the seedling environment simulation room 11. The inclined surface of the ceiling frame 32 is fixedly provided with simulation lights 35, and the simulation lights 35 are composed of several separate modules, each of which is connected to the PCL controller 31. A water spray pipe 33 is fixedly provided on the lower wall of the ceiling frame 32, and a plurality of nozzles 34 are provided on the water spray pipe 33. The water spray pipes 33 are all connected to the water pump controlled by the PCL controller 31. Another water pump controlled by the PCL controller 31 is also connected to a connecting pipe 17, and the connecting pipe 17 is interconnected with several transplanting racks 14.

[0051] When the PCL controller 31 automatically controls the water pump connected to the water spray pipe 33 to work according to the preset humidity setting value and the real-time monitored humidity data, in the simulated rainy environment, the PCL controller 31 remotely controls the motor 42 to work, pulls the seedling support arm 21 to rotate, and unfolds the soft film 202 to support the rice seedling bundle.

[0052] The present application also provides a breeding device system, comprising any breeding device;

[0053] The PCL controller 31 is responsible for receiving data from various sensors installed inside the seedling environment simulation chamber 11 and processing these data according to a preset program logic;

[0054] According to the processing results, the PCL controller 31 will send corresponding control instructions to the simulation lamp 35, the water pump connected to the water spray pipe 33, the temperature control module and the motor 42;

[0055] The PCL controller 31 controls the lights of different areas of the simulation lamp 35 to light up according to the season, time and the needs of rice growth, simulating natural lighting;

[0056] The PCL controller 31 automatically controls the water pump connected to the water spray pipe 33 to work according to the preset humidity setting value and the real-time monitored humidity data. When simulating a rainy environment, the PCL controller 31 controls the motor 42 to work, pulls the seedling support arm 21 to rotate, and unfolds the soft plastic sheet 202 to support the rice seedling bundle;

[0057] The PCL controller 31 adjusts the temperature of the seedling raising environment by controlling the temperature control module according to the preset temperature setting value and the real-time monitored temperature data.

[0058] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
