Description

Technical Field

[0001] This utility model relates to the field of rice pollination technology, and in particular to a flexible pollination pad for rice seed production. Background Technology

[0002] In hybrid rice breeding, parental materials are divided into female and male lines. The female line is sterile, with infertile pollen that cannot pollinate independently and relies on fertile pollen from the male line for cross-pollination. Without artificial intervention, the female line cannot be naturally pollinated, resulting in an extremely low seed set rate. Since the parent lines have different growth periods, staggered planting is necessary to ensure their flowering times coincide. Artificial pollination can compensate for the insufficient pollen dispersal efficiency under natural conditions.

[0003] Currently, artificial pollination typically involves using bamboo poles to tap the male rice ears, causing the male's pollen to fall onto the female's ears, thus completing the pollination process. However, tapping the rice ears with bamboo poles can cause them to break, resulting in a relatively high damage rate. Furthermore, the bamboo poles are quite heavy, increasing the workload and fatigue of workers during prolonged field work. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a lightweight, easy-to-operate, and non-damaging flexible pollination paddle for rice seed production.

[0005] Therefore, the technical solution of this utility model is: a flexible pollination paddle for rice seed production, including a handle, an elastic connector and a paddle surface, one end of the elastic connector is fixed to the handle and the other end is fixed to the paddle surface; the paddle surface is a circular silicone sheet, the edge of the silicone sheet is wrapped with a rubber strip, and the silicone sheet is provided with a grid pattern.

[0006] Based on the above solution and as a preferred embodiment of the above solution: the elastic connector includes a spring and a silicone protective sleeve. The two ends of the spring are fixed to the handle and the racket surface, respectively, and the silicone protective sleeve is wrapped around the outside of the spring.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the depth of the grid pattern on the racket surface is 0.5mm, and the grid pattern divides the racket surface into a pollen attachment area of ​​1cm×1cm.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the diameter of the racket face is 15cm, and the Shore hardness of the silicone sheet is 40A; the rubber strip is a ring structure with an opening in the inner ring, and is fitted onto the edge of the racket face; the rubber strip is 1cm wide, 3mm thick, and has a Shore hardness of 20A.

[0009] Based on the above solution and as a preferred solution: the handle is made of wood and has anti-slip texture on the surface; the end of the handle has a hanging hole.

[0010] When using, select the peak flowering period of the male parent, hold the handle and gently press the paddle surface against the male parent's rice ear, so that the grid pattern fits the surface of the rice ear; swing your wrist slightly and "lightly sweep" the paddle surface on the rice ear 2-3 times, so that the pollen is embedded in the grid pattern; then move the paddle surface above the female parent's rice ear, keep the paddle surface at a 45° angle to the ear layer, and gently tap the female parent's ear, so that the pollen in the grid is shaken off and completes pollination.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By gently pressing the male rice panicle with a silicone pad, the male pollen adheres to the grid pattern and is then transferred to the top of the female panicle. The pollen within the grid is dislodged by the vibration, completing the pollination process, which greatly improves the pollination rate and reduces the risk of damage to the rice panicle.

[0012] The handle is made of wood with a non-slip texture for easy grip; a silicone protective cover is placed over the spring to prevent it from pinching and damaging the rice ears; a soft rubber strip is wrapped around the outside of the racket face to prevent damage to the rice ears.

[0013] Its overall weight is much less than that of traditional bamboo poles, making it suitable for long-term field work. Attached Figure Description

There is a grid pattern 21 with a depth of 0.5mm and a size of 1cm×1cm on the surface of the silicone sheet. The grid pattern 21 can increase the pollen adhesion area, so that the pollen can adhere to the racket surface better.

[0021] Meanwhile, in order to avoid damaging the rice ears, a rubber strip 5 is wrapped around the edge of the silicone sheet of the paddle surface 2. The rubber strip 5 is a ring structure with an opening in the inner circle, and is fitted onto the edge of the paddle surface 2. The rubber strip 5 is 1cm wide, 3mm thick, and has a Shore hardness of 20A.

[0022] When using, select the peak flowering period of the male parent, hold the handle 1 and gently press the patting surface 2 against the male parent's rice ear, so that the grid pattern 21 fits the surface of the rice ear; swing your wrist slightly and "lightly sweep" the patting surface 2 on the rice ear 2-3 times, so that the pollen is embedded in the grid pattern 21; then move the patting surface 2 above the female parent's rice ear, keep the patting surface 2 at a 45° angle to the ear layer, and gently pat the female parent's ear, so that the pollen in the grid is shaken off and completes pollination.
