Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice pollination technology, specifically a pollination control device for rice breeding. Background Technology
[0002] Rice breeding refers to the scientific process of improving and optimizing rice varieties through genetics, molecular biology, and botany, using modern technology or traditional methods, in order to cultivate new varieties with higher yields, better quality, stronger resistance, or adaptation to specific environments. Rice breeding pollination control devices are tools or equipment specifically used to control pollination during rice hybridization breeding.
[0003] The patent document with publication number CN219248822U describes a pollination control device for rice breeding. The described scheme inserts a pollination component into the rice seedling and adjusts the insertion depth through a control component. This allows pollen to be evenly distributed into the rice seedling and improves the pollination effect. At the same time, the device has a compact structure that is easy to move and convenient for pollination workers to control, thus improving the convenience of breeding pollination.
[0004] The above-mentioned technologies have the problem of not being able to adjust the angle of the pollination components. Since the growth position and angle of rice inflorescences are diverse (e.g., different plant heights, stem and leaf shading, etc.), if the angle of the pollination components cannot be adjusted, it is difficult to achieve precise positioning of the maternal inflorescence. If the nozzle or thin tube is not aligned with the target inflorescence, the pollen may deviate from the stigma, resulting in pollination failure. In addition, the above-mentioned technologies also have the problem of not being able to adjust the length of the pollination tubes. Although the above-mentioned technologies can change the height of all pollination tubes, the height of rice plants varies greatly due to variety, growth stage, cultivation method and environmental conditions, making it impossible to align all pollination tubes with the inflorescence.

Then, the second motor 702 is started, causing it to rotate the threaded rod 703. Subsequently, under the action of the limiting rod 701, it causes the slider 200 to rise and fall, thereby moving the hollow plate 300 above the rice. Further adjustments are made according to the different heights of the rice. The electric telescopic rod 601 can be started, causing it to extend and retract the support plate 602 and the pollination tube 404, thereby moving the pollination tube 404 into the rice inflorescence. Pollen is then added into the feed pipe. Finally, the first motor 502 is started, causing it to rotate... The bolt conveying rod 503 rotates, gradually conveying pollen into the discharge pipe, and then into the pollination box 401. The suction fan 402 is then activated to blow air into the pollination box 401.
