Description

Technical Field

[0001] The present invention relates to the technical field of indica - japonica rice hybridization, and particularly to a functional integrated pollination - assisting tool for indica - japonica rice hybridization. Background Technique

[0002] Indica - japonica subspecies hybrid rice is a rice variety. It has large grain strength, good pressure - resistance performance, is not easy to produce broken rice during processing, has a relatively high rice yield rate, and has a small swelling property of the cooked rice. At the same time, it has the advantages of both indica rice and japonica rice, and realizes the complementarity of advantages and disadvantages. It is the most important way in the breeding research of super rice in China since the 1990s.

[0003] At the present stage, when carrying out indica - japonica rice hybridization pollination, it is mainly carried out by manual operation. Workers use scissors to process the flower buds of the female parent, and spray water to inactivate the anthers, cut the male parent, cut off the already - opened flower buds, and then cut open the unopened flower buds, and soak the bottom stem of the male parent in water for a corresponding time to promote the opening of the cut - open flower buds. Then, the taken - off male parent is shaken onto the bagged female parent to complete the work of hybridization pollination. The process is complicated, and the operation of the manual scissors depends too much on experience, which is not conducive to the cutting of the male parent flower buds. At the same time, the operation is also troublesome, which will reduce the operation efficiency. And only relying on shaking the male parent to achieve pollination, the efficiency is low and it is not convenient for actual manual operation. Summary of the Invention

[0004] In view of the deficiencies existing in the existing indica - japonica rice hybridization pollination operation process in the background technique, the present invention provides a functional integrated pollination - assisting tool for indica - japonica rice hybridization, which has the advantages of convenient sampling and pollination of the male parent and high efficiency, and solves the technical problems of troublesome and low - efficiency indica - japonica rice hybridization operation mentioned in the above background technique.

[0005] The present invention provides the following technical solution: A functional integrated pollination - assisting tool for indica - japonica rice hybridization, including an outer housing. A shear knife is inserted in the middle of the outer housing. A receiving cavity is connected to the outside of the outer housing. A bottom plate is arranged at the bottom of the receiving cavity. A filter plate is connected above the bottom plate. An air - charging bag is installed at the bottom of the receiving cavity.

[0006] Preferably, a support rod is connected to the bottom of the outer housing, and the bottom end of the support rod is a pointed structure. The outer housing is a structure that can be freely opened and closed by a hinge. A buckle capable of fixing the outer housing after closing is installed outside the outer housing. A movable magnet is connected to the left side of the inner wall of the outer housing. The movable magnet is connected by a spring. A fixed magnet is connected to the right side of the inner wall of the outer housing. The magnetic properties of the opposite sides of the fixed magnet and the movable magnet when the outer housing is closed are the same - level magnetic forces that generate mutual repulsion.

[0007] Preferably, the shearing knife is movably inserted into the housing body. The shearing knife is a hinged movable structure. A blade is connected inside the shearing knife. The two halves of the shearing knife are respectively inserted into the housing body. A clamping groove is formed on the left side of the shearing knife, and a movable magnetic block is movably clamped inside the clamping groove. After the housing body is closed, the blades of the shearing knife can be staggered with each other to achieve the shearing function.

[0008] Preferably, the accommodating cavities are symmetrically arranged on the outer side of the housing body. The bottom of the accommodating cavity is a concave structure. A plurality of clamping blocks evenly distributed up and down are connected to the inner side wall of the accommodating cavity. A limiting rod is connected to the other side inside the accommodating cavity, and the accommodating cavity is made of a transparent material.

[0009] Preferably, the bottom plates are symmetrically installed on the accommodating cavities on both sides of the housing body. The outer side of the bottom plate is connected to the inner wall of the accommodating cavity through a connecting outer edge. The connecting outer edge is made of a soft material and seals the gap between the side surface of the bottom plate and the accommodating cavity. A first telescopic rod is connected to the bottom of the bottom plate. The first telescopic rod is a rod body structure capable of freely telescoping. A gasbag cavity is connected to the bottom of the bottom plate. The gasbag cavity is made of a soft and airtight material. The bottom of the gasbag cavity is communicated with a first telescopic bladder. The first telescopic bladder is sleeved outside the first telescopic rod. After the first telescopic bladder is filled with gas, it can elongate. A plurality of one-way air valves are installed and connected to the surface of the bottom plate. The air pressure overflowing after the gasbag cavity expands enables the one-way air valves to jet air. An air hole is formed on one side of the top of the bottom plate.

[0010] Preferably, the filter plate is arranged above the bottom plate. The bottom of the filter plate is connected to the bottom plate through a second telescopic rod. A second telescopic bladder connecting the bottom of the filter plate and the bottom plate is arranged outside the second telescopic rod. The bottom of the second telescopic bladder is located outside the air hole. The second telescopic bladder is communicated with the inside of the gasbag cavity through the bottom plate. The bottom of the second telescopic rod is connected to the inner wall of the air hole. The top movable end of the second telescopic rod is connected to the bottom of the filter plate. The second telescopic rod is a multi-section sleeved rod body structure capable of freely telescoping. The filter plate is a grid plate. The filter plate is connected to the connecting part through a torsion spring shaft. In the natural state, the filter plate is flush with the bottom surface of the accommodating cavity. The top of the connecting part is movably sleeved on the limiting rod.

[0011] Preferably, the inflatable bladders are symmetrically installed at the bottom of the accommodating cavity. The bottom of the inflatable bladder is a valve capable of unidirectionally introducing air into the inflatable bladder. The top of the inflatable bladder is communicated with the connecting outer edge. The air valve at the bottom of the inflatable bladder starts to intake air only after the gas in the gasbag cavity and the second telescopic bladder is emptied.

[0012] The present invention has the following beneficial effects: 1. By arranging a fixed magnet block and a movable magnet block inside the outer shell, the present invention can facilitate the disassembly of the shear knife while ensuring the stability of the position of the shear knife fixed inside the outer shell. At the same time, through the action of the shear knife and the accommodating cavity, the sampling and chopping operations of the male parent rice can be realized, providing convenience for the sampling operation of the male parent pollen, and also eliminating the operation of soaking the male parent in water to promote flower opening, saving the operation time of indica-japonica hybrid rice pollination. At the same time, it can improve the operation efficiency and quality of cutting the flower buds, which is beneficial to the progress of indica-japonica hybrid operation pollination.

[0013] 2. By arranging a groove at the bottom of the accommodating cavity, the present invention can facilitate the collection of the male parent pollen, avoid the problem of sample spilling when the outer shell is opened. At the same time, through the cooperation of the air inflation bag, the air flow can be used to promote the movement of the pollen, thereby improving the pollination efficiency. And through the cooperation of the filter plate and the bottom plate, the upward movement operation can be realized when the air inflation bag acts, and the air flow can be used to promote the movement of the pollen, and finally the pollination effect can be achieved. Compared with manual operation, it can improve the pollination efficiency and quality, reduce the operation time, improve the manual operation efficiency, and realize the integrated function of male parent collection, processing and transfer.

[0014] 3. The present invention uses a torsion spring shaft to connect the filter plate and the connecting part, and through the cooperation of the clamping block, the filter plate can move up and down to vibrate, so as to promote the shedding of the male parent pollen on the filter plate. And through the action of the air flow ejected by the one-way air valve, it can further promote the movement of the pollen inside the outer shell, and finally achieve the effect of promoting pollination. And the filter plate can gradually rise above the female parent flower bud as the air bag inflates, which is beneficial to the falling of the pollen, and can also reduce the problem that other debris of the male parent affects pollination.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figure 1 , a pollination assistance tool for functional integrated indica-japonica rice hybridization. The indica-japonica rice hybridization pollination attachment tool includes an outer housing 1. The outer housing 1 is a symmetric structure connected by hinges, and a buckle is provided on its outside. The buckle is an ordinary buckle in the prior art and can be fixed when the outer housing 1 is closed. The outside of the outer housing 1 is connected with an accommodating cavity 3. The accommodating cavity 3 is a semi-circular structure, and the bottom of the accommodating cavity 3 is a concave groove structure, which can accommodate the cut fragments of the male parent. A shearing knife 2 is movably inserted in the middle of the outer housing 1. The shearing knife 2 is a two-half opening and closing structure connected by a hinge in the middle. The two halves of the shearing knife 2 are respectively inserted into the outer housing 1 from the top of the outer housing 1 and can open and close with the opening and closing of the outer housing 1. A blade 21 is connected inside the shearing knife 2. There are multiple groups of blades 21 evenly distributed up and down. After the shearing knife 2 is closed, the corresponding blades 21 are in misaligned contact to achieve the cutting function. A corresponding groove is provided at the bottom of the outer housing 1 to facilitate its sleeving on the outside of the rice stem without causing extrusion damage to the stem. By sleeving the outer housing 1 on the corresponding position outside the male parent and cooperating with the shearing knife 2, the shearing and shredding effects of the selected male parent position can be achieved, avoiding the need for manual use of scissors to cut the redundant part of the male parent and the outside of the flower bud, reducing the operation steps, and also avoiding the problem of accidental cutting by scissors, improving the efficiency and quality of male parent collection. And by shredding the male parent directly, it is beneficial for the pollen to contact the female parent, avoiding the step of soaking the male parent in water to promote the opening of the flower bud, saving operation time, and improving the actual pollination operation efficiency and quality of indica-japonica rice hybridization.

[0019] Please refer to Figure 2, at both ends of the inner wall of the outer housing 1, a fixed magnet block 101 and a movable magnet block 102 are respectively arranged. The fixed magnet block 101 is a magnet fixedly connected to the right side of the inner wall of the outer housing 1, and the movable magnet block 102 is a magnet movably inserted and connected to the left end of the outer housing 1 through a spring. After the outer housing 1 is closed, the opposite poles of the fixed magnet block 101 and the movable magnet block 102 are of the same sex. The repulsive force between the fixed magnet block 101 and the movable magnet block 102 causes the spring at the bottom of the movable magnet block 102 to contract, enabling the cutting knife 2 to be conveniently inserted into the outer housing 1. Please refer to Figure 3 , the left and right halves of the cutting knife 2 have different sizes and specifications. When it closes as the outer housing 1 closes, they can be sleeved with each other, so that the blades 21 can be staggered with each other to achieve the cutting function. A card slot 22 is provided on the left side of the cutting knife 2, and the position of the card slot 22 corresponds to that of the movable magnet block 102. After the cutting knife 2 is inserted into the outer housing 1, when the outer housing 1 is opened, the movable magnet block 102 is no longer affected by the magnetic force of the fixed magnet block 101 and is snapped into the card slot 22 under the action of the spring, which can fix the position of the cutting knife 2 on the outer housing 1, avoid the safety risk caused by the falling off of the cutting knife 2 when the outer housing 1 is opened, and at the same time does not affect the removal of the cutting knife 2. And the cutting knife 2 is movably installed, which can facilitate the subsequent transfer of male parent pollen and pollination work, and finally achieve the effect of integrating multiple functions such as sampling and pollination.

[0020] Please refer to Figures 4-5 , the bottom of the accommodation cavity 3 is connected with a bottom plate 5. The outer edge of the bottom plate 5 is connected with the inner wall of the accommodation cavity 3 through a connecting outer edge 53. The connecting outer edge 53 is made of elastic soft rubber film material, which can seal the gap between the bottom plate 5 and the inner wall of the accommodation cavity 3 while not affecting the up and down movement of the bottom plate 5, avoiding the problem that foreign impurities enter the bottom of the bottom plate 5 and are not easy to clean, and also facilitating the recycling of this pollination tool; the bottom of the bottom plate 5 is connected with an airbag cavity 52. The airbag cavity 52 is made of soft material and can accommodate gas inside. The bottom of the airbag cavity 52 is communicated with a first telescopic airbag 521. The first telescopic airbag 521 is an airbag structure that can be telescoped up and down. The bottom of the bottom plate 5 is connected with a first telescopic rod 51. The first telescopic rod 51 can freely telescope up and down, and the upper and lower ends of the first telescopic rod 51 are respectively connected to the bottom of the bottom plate 5 and the bottom of the accommodation cavity 3, which can support the bottom plate 5. The first telescopic rod 51 is located inside the first telescopic airbag 521. Therefore, when gas is filled into the airbag cavity 52, the first telescopic rod 51 can elongate as the first telescopic airbag 521 expands, realizing the upward movement of the bottom plate 5. The bottom of the accommodation cavity 3 is connected with an air filling bag 6. A one-way air valve that can only allow air to enter the air filling bag 6 from the outside is installed at the bottom of the air filling bag 6, and the air filling bag 6 is elastic and can return to its original state after losing the external force; Please refer to Figures 6-8, a connecting part 41 is provided on the top of the bottom plate 5. A second telescopic bladder 42 is connected to the bottom of the connecting part 41. An air hole 55 opened on the bottom plate 5 is provided inside the second telescopic bladder 42, so that the second telescopic bladder 42 can communicate with the inside of the air bladder cavity 52. A second telescopic rod 43 connected to the bottom of the filter plate 4 is provided inside the second telescopic bladder 42. The bottom end of the second telescopic rod 43 is fixed inside the air hole 55. At the same time, the second telescopic rod 43 does not block the air hole 55. The structure of the second telescopic rod 43 is similar to that of the first telescopic rod 51, and the second telescopic rod 43 is a rod structure with multiple sections of movable sleeves. It can perform corresponding telescoping as the filter plate 4 moves from the bottom of the accommodation cavity 3 to the top of the accommodation cavity 3. At the same time, the structure of the second telescopic bladder 42 is also the same as that of the first telescopic bladder 521. A limiting rod 32 is connected to one side inside the accommodation cavity 3. The top of the filter plate 4 is movably sleeved on the limiting rod 32, which can limit the up and down movement of the filter plate 4 and facilitate the use of the tool. And the second telescopic bladder 42 communicates with the air bladder cavity 52. The gas filled in the air bladder cavity 52 can also enter the second telescopic bladder 42 to make it expand and elongate, so as to realize the upward movement of the filter plate 4. The air outlet at the top of the air filling bladder 6 communicates with the air bladder cavity 52. After pressing the air filling bladder 6, the air inside the air filling bladder 6 can enter the air bladder cavity 52. The gas filled in the air bladder cavity 52 expands, making the first telescopic rod 51 also elongate, and the bottom plate 5 moves upward, so that the top plane of the bottom plate 5 can move to a position close to the flower spike, which is more conducive to the pollination operation. At the same time, the gas in the air bladder cavity 52 enters the second telescopic bladder 42 and makes it expand and elongate, which can make the filter plate 4 move upward. The filter plate 4 is connected to the connecting part 41 through a torsion spring shaft. A plurality of clamping blocks 31 are evenly distributed up and down on the inner wall of the accommodation cavity 3. The movable end on the outside of the filter plate 4 will contact the clamping blocks 31 continuously as the filter plate 4 moves upward as a whole and achieve a vibration effect. And the filter plate 4 is a grid plate structure. When the filter plate 4 moves upward and is vibrated, it can promote the shedding and scattering of the male parent pollen on the filter plate 4, which is conducive to the progress of cross-pollination.

[0021] Please refer to Figure 5, a plurality of one-way air valves 54 are provided on the bottom plate 5, and the one-way air valves 54 are internally communicated with the airbag cavity 52. When the air in the airbag cavity 52 and the second expansion bag 42 is sufficient and cannot continue to expand, the remaining gas in the inflation airbag 6 is discharged from the one-way air valve 54, and the pollen on the surface of the bottom plate 5 and inside the accommodation cavity 3 and the filter plate 4 moves with the airflow, thereby further promoting the pollination work, improving the pollination efficiency, and also reducing the contact between pollen and the human body during the pollination process, enhancing the pollination quality of indica-japonica rice hybridization, and being beneficial to the growth, development and research of rice and other operations; in addition, when the inflation airbag 6 is released, the inflation airbag 6 returns to its original shape, so that the gas in the second expansion bag 42 and the airbag cavity 52 will be re-sucked into the inflation airbag 6. Thereafter, the air valve at the bottom of the inflation airbag 6 absorbs gas from the outside under the action of air pressure to ensure that the inflation airbag 6 can return to its original shape, facilitating the use of the user; by setting the pollination tool for indica-japonica rice hybridization, the pollination operation of indica-japonica rice hybridization can be facilitated, the operation steps can be saved, the contact between the human body and tools such as scissors can be reduced, the operation safety can be improved, and at the same time, the use of multiple blades to cut the male parent can improve the pollen powder yield rate and enhance the quality and efficiency of hybridization.

[0022] The working principle of the usage method of the present invention is as follows: Select a suitable male parent, then spray water on the outside of the male parent to inactivate the pollen on the outside of the male parent. Then, put the outer shell 1 on the outside of the male parent, and make the flowering part at the top of the male parent located above the outer shell 1. Then, close the outer shell 1, and the shear knife 2 also cuts the selected male parent along with the closing of the outer shell 1. Multiple blades 21 act simultaneously to crush the selected male parent, and the chopped male parent plants fall into the receiving cavities 3 on both sides of the shear knife 2 and are stored. Or gently shaking the outer shell 1 can also make the samples remaining on the shear knife 2 fall into the receiving cavity 3. After the outer shell 1 is closed, the fixed magnet 101 and the movable magnet 102 approach. Due to the repulsion of like-level magnetic forces, the movable magnet 102 moves away from the fixed magnet 101 and leaves the card slot 22. At this time, the shear knife 2 can be pulled out of the outer shell 1 and placed aside. Trim the outer bud of the female parent to expose the internal stamens. Then, move the outer shell 1 to the outside of the female parent, open the outer shell 1 and put the outer shell 1 on the outside of the female parent spike, and at the same time make the support rod 103 inserted into the soil to fix the position of the outer shell 1, and close the buckle outside the outer shell 1 to make the outer shell 1 closed and fixed. At this time, the support rod 103 is inserted into the soil to support the outer shell 1, and the outer shell 1 and the receiving cavity 3 are sleeved on the outside of the female parent spike. Repeatedly pinch the air bag 6, and the air bag 6 inflates into the air bag cavity 52. The air bag cavity 52 and the first expansion bag 521 expand and make the first expansion rod 51 extend. The extension of the first expansion rod 51 makes the bottom plate 5 and the filter plate 4 move upward. When the air pressure in the air bag cavity 52 rises to the maximum value, the gas continues to enter the second expansion bag 42 and makes the second expansion rod 43 extend. The filter plate 4 moves upward along the limiting rod 32. When the filter plate 4 moves upward, one end is affected by the receiving block 31 and deflects back and forth. The one end of the filter plate 4 deflects back and forth to achieve up-and-down reciprocating vibration, making the male parent fragments falling on the filter plate 4 vibrate reciprocally. The pollen on the male parent falls off due to the vibration. When the second expansion bag 42 expands to the maximum value, the filter plate 4 moves to the top inside the receiving cavity 3. At this time, the air pressure inside the air bag cavity 52 is greater than the air pressure of the one-way air valve 54, and the gas inside the air bag 6 sprays out from the one-way air valve 54. The gas sprayed out from the one-way air valve 54 makes the pollen inside the receiving cavity 3 and the pollen falling on the bottom plate 5 move with the air flow, so that the pollen falls on the female parent spike to achieve cross-pollination. After loosening the air bag 6, the air bag 6 returns to its original shape, and the gas in the air bag cavity 52 and the second expansion bag 42 is re-sucked into the air bag 6. When the gas inside the air bag cavity 52 and the second expansion bag 42 is emptied, the air valve at the bottom of the air bag 6 starts to suck air from the outside until the air bag 6 returns to its original position. Repeatedly press the air bag 6 to make the male parent pollen on the filter plate 4 shake off as completely as possible. Finally, make a mark on the outside of the outer shell 1; after the outer shell 1 is used up, open the buckle outside the outer shell 1 and remove the outer shell 1 from the outside of the female parent, and then clean the inside of the outer shell 1 and other operations to prepare for the next use.
