At the same time, the hair dryer cooperates with the annular base at the bottom of the collection sleeve to continuously circulate the scattered pollen in the collection sleeve, reducing the waste of pollen and improving the breeding pollination efficiency of the female parent wheat. Among them, the annular base is set as a structure that can be turned up and down, and it can also efficiently remove the residual pollen in the collection sleeve in cooperation with the hair dryer. This avoids the interference phenomenon that the residual pollen in the pollen collector will cause cross-infection of the pollen collected in the next batch, and prevents the occurrence of technical problems that affect the effectiveness of breeding pollination.

Description

Technical Field

[0001] The present invention relates to the field of wheat breeding, and particularly to a pollen collector for wheat breeding. Background Art

[0002] Pollination in wheat cross-breeding is a crucial step, including the main step of breeding pollination. After removing the immature stamens from the female parent wheat, the mature pollen of the male parent wheat is transferred into each floret of the female parent wheat. During this period, the female parent wheat cannot be interfered by the pollen from other wheat plants in the outside world. The existing pollen collectors for wheat breeding, such as a wheat pollen collector disclosed in Patent CN217694398U, can automatically collect the pollen of the male parent wheat and pour the collected pollen of the male parent wheat onto the female parent wheat, improving the pollen collection efficiency and reducing waste. However, this implementation will result in a large amount of pollen remaining in the pollen collector. When it is necessary to collect pollen from the male parent wheat of the next different variety, the pollen remaining in the pollen collector will cause the phenomenon of cross-infection interference to the pollen collected in the next batch, affecting the effectiveness of pollination in the entire wheat cross-breeding.

Detailed implementation manners

[0025] The preferred technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Embodiment 1: A pollen collector for wheat breeding, as Figures 1-9 shown, includes a collection sleeve 1, a dial ring 2, an inner ring 21, a clamping block 22, an inner compression spring 23, a spur gear 24, a ring gear 25, a fixing frame 3 and a hair dryer 4; a plurality of levers 11 are provided on the inner wall of the collection sleeve 1; the collection sleeve 1 is rotatably connected with a dial ring 2; an installation part 202 is arranged inside the dial ring 2, and the installation part 202 is rotatably connected with an inner ring 21; two clamping blocks 22 are slidably connected inside the inner ring 21; an inner compression spring 23 is fixedly connected between each of the two clamping blocks 22 and the inner ring 21, and the two clamping blocks 22 are in close contact with each other; a spur gear 24 is fixedly connected to the inner ring 21; a fixing frame 3 is fixedly connected to the collection sleeve 1; a ring gear 25 is fixedly connected to the fixing frame 3; the spur gear 24 is meshed with the ring gear 25; the fixing frame 3 is rotatably connected with a hair dryer 4 through a rotating shaft, the hair dryer 4 is internally provided with a power supply, and in the initial state, the air outlet of the hair dryer 4 is aligned with the upper port of the collection sleeve 1.

[0027] As Figure 3As shown, all the lever rods 11 are set to a downwardly inclined structure. When the lever rods 11 are in an inclined state, it can not only increase the effective contact area between the lever rods 11 and the male parent wheat, but also reduce the moving interference caused by the lever rods 11 to the rotating male parent wheat. The lever rods 11 are all made of soft rubber material. During the continuous contact with the rotating male parent wheat, the lever rods 11 made of soft rubber material can reduce the damage to the male parent wheat.

[0028] As Figure 3 shown, a ring base 12 is fixedly connected to the bottom of the collection sleeve 1, and a upward convex structure is provided in the middle of the ring base 12. Correspondingly, a ring groove structure surrounding the convex structure is provided on the ring base 12. The ring base 12 is made of a rubber material that can be turned inside out.

[0029] The breeding pollination working steps of a pollen collector for wheat breeding according to the present invention are as follows. First, the user turns the hair dryer 4 away from the upper port of the collection sleeve 1 from the fixing frame 3. Then, the user uses two fingers of one hand to push the two clamping blocks 22 apart to both sides respectively. At the same time, the two clamping blocks 22 drive the two inner compression springs 23 to compress respectively. And the user uses the other hand to pass the male parent wheat through between the two clamping blocks 22 inside the inner ring 21 with the ear of wheat facing down and the wheat stalk facing up. The male parent wheat used is the wheat with a complete ear of wheat and mature pollen, and the wheat stalk of the male parent wheat has been pre-treated by shortening, so that the ear of wheat of the male parent wheat enters the inside of the collection sleeve 1 downward. When the wheat stalk of the male parent wheat is located between the two clamping blocks 22, the user releases the two clamping blocks 22. The two compressed inner compression springs 23 drive the two clamping blocks 22 to move towards each other and reset to clamp the wheat stalk of the male parent wheat, so that the ear of wheat of the male parent wheat remains inside the collection sleeve 1. Then, the user turns the hair dryer 4 back to its original position to align with the upper port of the collection sleeve 1.

[0030] After that, the user sleeved the lower port of the collection sleeve 1 outside the pollination part of the ear of the female parent wheat, and sleeved the annular base 12 outside the stalk of the female parent wheat and kept the middle part bulging upward, and made the pollination part of the ear of the female parent wheat stay in the axial center area of the collection sleeve 1. At this time, the ear of the male parent wheat was adjacent to the pollination part of the ear of the female parent wheat. Then, the user slowly rotated the dial ring 2 to drive the inner ring 21 and the male parent wheat clamped by the clamping block 22 to revolve around the pollination part of the ear of the female parent wheat. At the same time, when the inner ring 21 drove the spur gear 24 to move along the annular gear 25, the stationary annular gear 25 engaged with the rotating spur gear 24 to drive the inner ring 21 and the male parent wheat clamped by the clamping block 22 to rotate. During the revolution of the male parent wheat, it continuously collided with the lever 11 in each area of the collection sleeve 1 through self-rotation. During this process, the pollen on the male parent continuously scattered evenly around the pollination part of the ear of the female parent wheat during continuous collisions, so that the pollen was evenly scattered on the pollination part of the ear of the female parent wheat. Most of the pollen that did not effectively fall on the pollination part of the ear of the female parent wheat would fall into the annular groove structure of the annular base 12. Then, the user turned on the low-speed gear of the hair dryer 4, and the hair dryer 4 continuously blew low-speed air from top to bottom into the collection sleeve 1. The low-speed air continuously blew up the pollen that fell into the annular groove structure of the annular base 12 again, so that the pollen continuously circulated in each area of the collection sleeve 1. This not only avoided a large amount of pollen from floating out into the air and interfering with the surrounding other female parent wheats, but also improved the acceptance effect of the pollen by the pollination part of the ear of the female parent wheat located inside the collection sleeve 1, thereby improving the breeding pollination efficiency of the female parent wheat.

[0031] It should be noted that in nature, wheat mainly spreads pollen through wind and insects, and the stigma of the pistil of wheat is in a loose feather shape, which can make the pollen in contact with it not be interfered by air flow. Therefore, there is no need to worry that the low-speed air flow blown by the hair dryer 4 will affect the pollinated wheat.

[0032] The cleaning work steps of the residual pollen in the collection sleeve 1 of a pollen collector for wheat breeding according to the present invention are as follows. After finishing the breeding pollination work on the female parent wheat, the user removes the collection sleeve 1 from the female parent wheat, removes the male parent wheat from the clamping block 22, and then puts the lower port of the collection sleeve 1 into the carried water bucket. The carried water bucket is filled with pure water. Then, the user turns the middle area of the annular base 12 outwards from the inside of the collection sleeve 1, as Figure 9As shown, at this time, there is no longer a circular groove structure in the circular base 12. At the same time, the user turns on the high-speed gear of the hair dryer 4, and the hair dryer 4 continuously blows high-speed air flow from top to bottom into the collection sleeve 1. The high-speed air flow continuously blows the pollen remaining on the inner wall of the collection sleeve 1 and the lever 11 down into the carried water bucket, and the blown pollen is collected by the purified water in the carried water bucket, completing the cleaning work of the pollen remaining in the collection sleeve 1.

[0033] Embodiment 2: As Figures 1-7 shown, the difference between this embodiment and Embodiment 1 is that a cavity structure is provided inside the fixing frame 3; a liquid storage bladder 5 is fixedly connected to the fixing frame 3, and a cleaning liquid is contained in the liquid storage bladder 5; two infusion tubes 51 are commonly connected between the liquid storage bladder 5 and the cavity structure of the fixing frame 3; a plurality of liquid spraying nozzles 301 communicating with the cavity structure are provided on the fixing frame 3, and the outlet ends of the liquid spraying nozzles 301 are all located above the annular gear 25; all the liquid spraying nozzles 301 are arranged in a structure inclined downward into the collection sleeve 1; an air flow heater is built in the hair dryer 4; a plurality of inclined plates 26 are fixedly connected inside the dial ring 2.

[0034] During the process of the user turning on the hair dryer 4 to clean the pollen remaining in the collection sleeve 1, the user slowly presses the liquid storage bladder 5 with one hand, so that the cleaning liquid in the liquid storage bladder 5 enters the cavity structure of the fixing frame 3 through the infusion tube 51, and the cleaning liquid is then sprayed downward into the collection sleeve 1 through the respective liquid spraying nozzles 301 of the fixing frame 3. At the same time, the user slowly rotates the dial ring 2 with the other hand to drive the inclined plate 26 to rotate, and the rotating inclined plate 26 drains the cleaning liquid sprayed from the liquid spraying nozzles 301 to various areas in the lower part of the collection sleeve 1, realizing that the cleaning liquid can efficiently spray and clean each area of the inner wall of the collection sleeve 1 and the surfaces of all the levers 11, further improving the cleaning efficiency of the pollen remaining in the collection sleeve 1. After the user stops squeezing the liquid storage bladder 5, the spraying and cleaning treatment of the surface of the lever 11 ends. Then the user turns on the air flow heater of the hair dryer 4, and the hair dryer 4 continuously blows hot air flow into the collection sleeve 1, so that the inner wall of the collection sleeve 1 and the surfaces of the levers 11 are quickly dried.

[0035] Embodiment 3: As Figures 1-8 shown, the difference between this embodiment and Embodiment 1 is that a clamping assembly is provided on the collection sleeve 1 of this embodiment; a sleeve bag 7 is clamped on the clamping assembly; an opening is provided on each of the upper and lower sides of the sleeve bag 7, the clamping assembly clamps the upper opening of the sleeve bag 7, and the middle part of the upper opening of the clamping assembly is sleeved on the outer surface of the collection sleeve 1; a paste layer is provided on each of the two side openings of the sleeve bag 7; the clamping assembly is composed of a fixed clamping plate 61, a movable clamping plate 62 and an external compression spring 63; two fixed clamping plates 61 are fixedly connected to the collection sleeve 1; a movable clamping plate 62 is slidably connected between the two fixed clamping plates 61; an external compression spring 63 is fixedly connected between each of the two fixed clamping plates 61 and the movable clamping plate 62.

[0036] When the user pushes the clamping part of the movable splint 62, the two movable splints 62 can be controlled to cooperate with the fixed splint 61 to clamp the left and right sides of the upper opening of the sleeve bag 7 respectively. Then, the male parent wheat is put into the collection sleeve 1 and clamped between the two clamping blocks 22 according to the above steps. At the same time, the lower opening of the sleeve bag 7 is sleeved outside the pollination part of the ear of the female parent wheat, and the paste layer of the lower opening of the sleeve bag 7 is used to pinch the lower opening together, so that the lower opening of the sleeve bag 7 remains sleeved outside the pollination part of the ear of the female parent wheat and is in a closed state. At this time, both the male parent wheat in the collection sleeve 1 and the pollination part of the ear of the female parent wheat are located in the sleeve bag 7, realizing that in the subsequent breeding pollination work, the pollen falling out of the collection sleeve 1 will remain in the sleeve bag 7 and will not spread to the external environment.

[0037] After the breeding pollination work is completed, the user removes the collection sleeve 1 and the clamping assembly from the sleeve bag 7, and timely pinches the upper opening of the sleeve bag 7 together by using the paste layer of the upper opening of the sleeve bag 7, so as to prevent the pollen in the external environment from entering the sleeve bag 7 and contacting the pollination part of the ear of the female parent wheat, ensuring the effectiveness of the breeding pollination in preventing external infection.
