Description

Technical Field

[0001] This utility model relates to the field of wheat pollination technology, specifically to a high-efficiency pollen collection and precision pollination device for wheat hybridization breeding. Background Technology

[0002] Wheat breeding has been carried out in my country for decades. Through the hard work of wheat breeders, many excellent varieties have been selected. However, with the continuous changes in climate, pathogen physiological races, and consumer demands, wheat breeders must continue their efforts to breed new wheat varieties that are disease-resistant, of high quality, high-yielding, and widely applicable. The first step in wheat breeding is the pairing of parents, or cross-pollination. The traditional method involves inserting the pollen-laden ear of the male parent into the hybridization bag of the emasculated female parent from the top and rotating it back and forth, allowing the pollen to fall freely onto the stigma of the female parent ear. This method results in a lot of pollen being wasted, leading to a low seed setting rate. Furthermore, it requires breaking the male parent ear, meaning pollen can only be collected once, and this method needs improvement.

[0003] Therefore, we proposed a high-efficiency pollen collection and precision pollination device for wheat hybridization breeding to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to solve the problems of traditional wheat pollen collection and pollination methods. These methods involve inserting the pollen-laden male ear into a hybridization bag containing the emasculated female parent from the top and rotating it back and forth, allowing the pollen to fall freely onto the stigma of the female ear. This results in a lot of pollen being wasted, leading to a low seed setting rate. Furthermore, the male ear needs to be broken, meaning that pollen can only be collected once. These methods need to be improved.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency pollen collection and precise pollination device for wheat hybridization breeding, comprising: a wheat ear holder and a pollination tube;

[0006] Two powder-collecting cloths are set on the wheat ear holder;

[0007] A powder collection box is located at the bottom of the powder collection cloth, and a flexible tube is provided on the powder collection box;

[0008] Two one-way mechanisms are located at the bottom of the pollination tube. One of the one-way mechanisms is connected to a pollination tube, and the other one-way mechanism is connected to a flexible tube.

[0009] Furthermore, the wheat ear holder includes two annular rods, each with a connecting rod. One end of each connecting rod has a gripping rod, and the two connecting rods are hinged together. Wheat ear grooves are formed on the contact surfaces of the two annular rods, and the two powder-collecting cloths are respectively connected to the two annular rods.

[0010] Furthermore, the powder collection box includes a box body, a box cover is threadedly connected to the box body, two powder inlet pipes are provided on the box cover, a powder outlet pipe is provided at the bottom of the box body, a first connecting pipe connected to the powder collection cloth is threadedly connected to the powder inlet pipe, and a second connecting pipe connected to the flexible tube is threadedly connected to the powder outlet pipe.

[0011] Furthermore, the pollination cylinder includes a cylinder body, inside which a push rod and a piston block are disposed. A push plate is connected to the top end of the push rod, and a mechanism spring is disposed between the push plate and the top end of the pollination cylinder.

[0012] Furthermore, the two one-way mechanisms are in opposite directions. Each one-way mechanism includes a mechanism cylinder, a partition plate is provided inside the mechanism cylinder, a spring cylinder is provided on the partition plate, a compression spring and a limiting plate are provided inside the spring cylinder, a connecting post is connected to the limiting plate, a baffle is connected to one end of the connecting post, a flow hole is provided on the partition plate, and a connecting hole communicating with the mechanism cylinder is provided at the bottom end of the cylinder.

[0013] Furthermore, a screen is provided inside the box near the top.

[0014] Furthermore, a set of finger rings is symmetrically connected to the side of the cylinder near the top.

[0015] The beneficial effects of this utility model are as follows: By setting up a wheat ear clamp and a pollination tube, and by setting a pollen-collecting cloth on the wheat ear clamp, a pollen-collecting box at the bottom of the pollen-collecting cloth, and a flexible tube on the pollen-collecting box, and by connecting a pollination tube to a one-way mechanism at the bottom of the pollination tube and connecting another one-way mechanism to the flexible tube, the male ear can be clamped by the wheat ear clamp, so that the male ear is in the ear groove, and then the male ear is shaken to make the pollen fall into the pollen-collecting cloth and slide into the pollen-collecting box for collection. There is no need to break the male ear, which facilitates multiple subsequent pollen collections. The pollen that falls into the pollen-collecting box can be drawn into the pollination tube by the negative pressure generated by the pollination tube, and then sprayed onto the stigma of the female ear through the pollination tube, preventing pollen from falling into the wrong place and wasting it, and greatly improving the seed setting rate.

By gripping the gripping rod 13 of the wheat ear clamp 1, the two ring rods 11 are rotated to clamp the male ear, so that the male ear is in the wheat ear groove 14. Then, the male ear is shaken to make the pollen fall into the pollen collection cloth 3 and slide into the pollen collection box 4 for collection.
