A pollination control device for rice breeding

Abstract

The invention provides a pollination control device for rice breeding; when pollinating the breeding rice, a control cover is wrapped around the panicle area of ​​the rice, and a fan is started to generate airflow. Under the action of the airflow, the end of the pollen bag moves downward and turns over, so that the pollen in the pollen bag follows the airflow and is scattered on the panicle, and the loss of pollen is controlled by the control cover, thereby improving the pollination rate. At the same time, under the action of the airflow, the rice is swayed, so that excessive pollen of the rice falls off. After the pollination is completed, the fan is reversed, and the airflow goes up at this time. Under the action of the airflow, the pollen air in the control cover is sucked up along with the airflow. At the same time, under the action of the airflow, the end of the pollen bag moves upward, so that the pollen in the airflow can be concentrated and collected inside the pollen bag, and the airflow passes through the outer wall of the pollen bag. As the airflow velocity decreases, the pollen bag is deflated, so that the excess pollen is recovered through the pollen bag, thereby improving the pollen utilization rate.

Description

Technical Field

[0001] The invention relates to the technical field of rice breeding, and in particular to a pollination control device used for rice breeding. Background Art

[0002] Rice is a cereal crop of the genus Oryza, with the representative species being Oryza sativa L., which is native to China and India. The ancestors of the Yangtze River Basin in China planted rice 7,000 years ago. Rice is divided into indica rice and japonica rice, early rice and mid-late rice, glutinous rice and non-glutinous rice according to the type of rice grains, and is divided into conventional rice and hybrid rice according to the seed retention method. In the process of rice breeding, pollination control is required;

[0003] However, when the existing pollination control device is used, pollen is scattered into the rice panicle area for pollination, resulting in a waste of pollen, a low pollination rate and a low pollen utilization rate, and the pollen cannot be recovered. Therefore, a pollination control device for rice breeding is proposed. Summary of the invention

[0004] In order to solve at least one of the above-mentioned technical shortcomings, the present invention provides a pollination control device for rice breeding, wherein the top outer wall of the outer cylinder is provided with an air permeable net, a fan is installed inside the outer cylinder, a pollen bag fixed inside the outer cylinder is installed directly below the fan, and a control cover for wrapping around the rice spike area is installed at the bottom of the outer cylinder.

[0005] Furthermore, a pollen bin is provided on the outer wall of the outer cylinder from the side, a bin door is provided on the pollen bin through a hinge rotation connection, a plurality of threaded tubes are evenly provided on the surface of the pollen bin, and the bottom end of the pollen bag is threadedly connected to the threaded tube.

[0006] Furthermore, the bottom of the pollen bag is a threaded tube, the middle part is a mesh-shaped arrangement, and the top part is a flexible hemispherical bag-shaped arrangement.

[0007] Furthermore, the control cover includes a connecting tube fixedly connected to the bottom end of the outer cylinder, a hemispherical shell is fixedly connected to the bottom of the connecting tube, an arc groove coaxial with the connecting tube is provided at the bottom of the hemispherical shell, a rotating ring is rotatably connected to the bottom end of the connecting tube through a bearing, a gear ring is integrally connected to the top of the rotating ring, a driving mechanism for driving the gear ring to rotate is fixedly connected to the outer wall of the connecting tube, a control arc is provided on the outer wall of the bottom end of the rotating ring, and a shrink film is fixedly connected between the control arc and the hemispherical shell.

[0008] Furthermore, the driving mechanism includes a servo motor fixed on the connecting pipe, and an output end of the servo motor is fixedly connected to a gear meshing with the gear ring.

[0009] Furthermore, the top, middle and bottom of the hemispherical shell are all provided with limit holes, and a limit rod movably connected to the limit hole is fixedly connected to the control arc, and the limit rod is movably connected to the shrink film.

[0010] Furthermore, a first elastic tightening piece is fixedly connected to the bottom of the arc-shaped groove, and a second elastic tightening piece is fixedly connected to the bottom of the shrink film.

[0011] Beneficial effects:

[0012] 1. Compared with the prior art, when pollinating breeding rice, the present invention wraps the control cover around the panicle area of ​​the rice, starts the fan, and generates airflow. Under the action of the airflow, the end of the pollen bag moves downward and turns over, so that the pollen inside the pollen bag follows the airflow and is scattered on the panicle. The loss of pollen is controlled by the control cover, thereby improving the pollination rate. At the same time, under the action of the airflow, the rice is swayed, so that excess pollen of the rice falls off. After pollination is completed, the fan is reversed. At this time, the airflow goes up. Under the action of the airflow, the pollen air inside the control cover is sucked up with the airflow. At the same time, under the action of the airflow, the end of the pollen bag moves upward, so that the pollen in the airflow can be concentrated and collected inside the pollen bag. The airflow passes through the outer wall of the pollen bag. As the airflow velocity decreases, the pollen bag is deflated, thereby recycling excess pollen through the pollen bag, thereby improving the pollen utilization rate.

[0013] 2. When pollinating rice, insert the hemispherical shell from one side of the rice plant so that the hemispherical shell is located on one side of the rice spike area. The servo motor works to drive the gear to work, so that the gear ring rotates under the drive of the gear, the rotating ring rotates, the control arc rotates, and the control arc pulls the shrink film assembly originally squeezed on the limit rod to unfold. At this time, the limit rod moves inside the limit hole. When the control arc rotates about 170°, the shrink film is completely opened. At this time, the hemispherical shell and the shrink film just wrap the rice spike area. At this time, the elastic tightening piece 1 and the elastic tightening piece 2 themselves tighten the arc groove area, start the fan, and the fan generates airflow. Under the action of the airflow, the end of the pollen bag moves downward and turns over, so that the pollen inside the pollen bag follows the airflow and is scattered onto the flower spike. The loss of pollen is controlled by the hemispherical shell and the shrink film, thereby improving the pollination rate. After pollination is completed, the fan reverses, and the airflow goes up at this time. Under the action of the airflow, the pollen in the air inside the hemispherical shell and the shrink film is sucked up with the airflow. At the same time, under the action of the airflow, the end of the pollen bag moves upward, so that the pollen in the airflow can be concentrated and collected inside the pollen bag. The airflow passes through the outer wall of the pollen bag, and as the airflow velocity decreases, the pollen bag deflates, thereby recovering excess pollen through the pollen bag and improving the pollen utilization rate.

DETAILED DESCRIPTION

[0025] Please refer to Figures 1 to 9 ;

[0026] This embodiment provides a pollination control device for rice breeding, referring to Figure 1 and Figure 2 The top outer wall of the outer tube 1 is provided with an air-permeable net 101, a fan 2 is installed inside the outer tube 1, a pollen bag 5 fixed inside the outer tube 1 is installed directly below the fan 2, and a control cover 3 for wrapping the rice spike area is installed at the bottom of the outer tube 1.

[0027] In specific implementation, when pollinating the breeding rice, the control cover 3 is wrapped around the panicle area of ​​the rice, and the fan 2 is started to generate airflow. Under the action of the airflow, the end of the pollen bag 5 moves downward and turns over, so that the pollen inside the pollen bag 5 follows the airflow and is scattered on the panicle. The loss of pollen is controlled by the control cover 3, thereby improving the pollination rate. At the same time, under the action of the airflow, the rice is swayed, so that excessive pollen of the rice falls off. After the pollination is completed, the fan 2 is reversed. At this time, the airflow goes up. Under the action of the airflow, the pollen air inside the control cover 3 is sucked up with the airflow. At the same time, under the action of the airflow, the end of the pollen bag 5 moves upward, so that the pollen in the airflow can be concentrated and collected inside the pollen bag 5. The airflow passes through the outer wall of the pollen bag 5. As the airflow velocity decreases, the pollen bag 5 deflates, thereby recovering excess pollen through the pollen bag 5, thereby improving the pollen utilization rate.

[0028] Furthermore, a pollen bin 102 is provided on the outer wall of the outer tube 1 from the side, and a bin door 103 is rotatably connected to the pollen bin 102 via a hinge. A plurality of threaded tubes 121 are evenly provided on the surface of the pollen bin 102 , and the bottom end of the pollen bag 5 is threadedly connected to the threaded tube 121 .

[0029] In specific implementation, the arrangement of the bin door 103 makes it easy to install and replace the pollen bag 5 inside the pollen bin 102 .

[0030] For further reference, Fig. 9 The bottom of the pollen bag 5 is a threaded tube, the middle part is a mesh-shaped arrangement, and the top part is a flexible hemispherical bag-shaped arrangement.

[0031] In specific implementation, when the pollen bag 5 encounters an ascending airflow, the top of the pollen bag 5 moves upward under the action of the airflow, and the airflow passes through the middle. At this time, the pollen bag 5 collects the pollen in the airflow; when the pollen bag 5 encounters a descending airflow, the top of the pollen bag 5 moves downward under the action of the airflow, causing the pollen bag 5 to flip down, so that the pollen inside the pollen bag 5 is scattered, and pollination is carried out at this time.

[0032] For further reference, Figures 5 to 8 The control cover 3 includes a connecting tube 301 fixedly connected to the bottom end of the outer tube 1, a hemispherical shell 302 is fixedly connected to the bottom of the connecting tube 301, an arc groove coaxial with the connecting tube 301 is provided at the bottom of the hemispherical shell 302, a rotating ring 305 is rotatably connected to the bottom end of the connecting tube 301 through a bearing, a gear ring 351 is integrally connected to the top of the rotating ring 305, a driving mechanism 4 for driving the gear ring 351 to rotate is fixedly connected to the outer wall of the connecting tube 301, a control arc 306 is provided on the outer wall of the bottom end of the rotating ring 305, and a shrink film 307 is fixedly connected between the control arc 306 and the hemispherical shell 302.

[0033] In specific implementation, the driving mechanism 4 works to drive the gear ring 351 to rotate, so that the rotating ring 305 rotates, and the control arc 306 rotates, so that the control arc 306 drives the shrink film 307 to wrap the rice spike area.

[0034] For further reference, Figure 2 The driving mechanism 4 includes a servo motor 401 fixed on the connecting pipe 301 , and an output end of the servo motor 401 is fixedly connected to a gear 402 meshing with the gear ring 351 .

[0035] In specific implementation, when the driving mechanism 4 is driving, the servo motor 401 works, driving the gear 402 to work, so that the gear ring 351 rotates under the drive of the gear 402, so that the rotating ring 305 rotates, the control arc 306 rotates, and the shrink film 307 is wrapped and opened.

[0036] For further reference, Figure 6 The top, middle and bottom of the hemispherical shell 302 are all provided with limiting holes 303 , and a limiting rod 361 movably connected to the limiting hole 303 is fixedly connected to the control arc 306 , and the limiting rod 361 is movably connected to the shrink film 307 .

[0037] In a specific implementation, when the control arc 306 rotates, the shrink film 307 is folded on the limiting rod 361. When the control arc 306 is fully opened, the shrink film 307 is completely squeezed on the limiting rod 361. When the control arc 306 is fully closed, the shrink film 307 is completely unfolded on the limiting rod 361. At this time, the shrink film 307 and the hemispherical shell 302 form a sphere, so that the rice spike area is wrapped inside.

[0038] For further reference, Figure 6 and Figure 7 The bottom of the arc groove is fixedly connected with an elastic tightening piece 1 304, and the bottom of the shrink film 307 is fixedly connected with an elastic tightening piece 2 308.

[0039] In a specific implementation, the elastic tightening piece 1 304 and the elastic tightening piece 2 308 are arranged so that during pollination, the rice stalks are inside the arc groove, and the elastic force of the elastic tightening piece 1 304 and the elastic tightening piece 2 308 tightens the arc groove area, thereby reducing the loss of pollen;

[0040] When wrapping the inflorescence area of ​​rice, the hemispherical shell 302 is inserted from one side of the rice plant so that the hemispherical shell 302 is located on one side of the inflorescence area of ​​rice, and the servo motor 401 works to drive the gear 402 to work, so that the gear ring 351 rotates under the drive of the gear 402, so that the rotating ring 305 rotates, so that the control arc 306 rotates, so that the control arc 306 pulls the shrink film 307 component originally squeezed on the limit rod 361 to unfold, and at this time the limit rod 361 moves inside the limit hole 303, and when the control arc 306 rotates about 170°, the shrink film 307 is fully opened, and at this time the hemispherical shell 302 and the shrink film 307 just wrap the inflorescence area of ​​rice, and at this time, the elastic force of the elastic tightening piece 1 304 and the elastic tightening piece 2 308 themselves tightens the arc groove area. The rows are tied tightly, and the fan 2 is started to generate an airflow. Under the action of the airflow, the end of the pollen bag 5 moves downward and turns over, so that the pollen inside the pollen bag 5 follows the airflow and is scattered on the flower spike. The loss of pollen is controlled by the hemispherical shell 302 and the shrink film 307, thereby improving the pollination rate. After the pollination is completed, the fan 2 is reversed. At this time, the airflow goes up. Under the action of the airflow, the pollen in the air inside the hemispherical shell 302 and the shrink film 307 is sucked up with the airflow. At the same time, under the action of the airflow, the end of the pollen bag 5 moves upward, so that the pollen in the airflow can be concentrated and collected inside the pollen bag 5. The airflow passes through the outer wall of the pollen bag 5. As the airflow velocity decreases, the pollen bag 5 deflates, thereby recovering excess pollen through the pollen bag 5, thereby improving the pollen utilization rate.
