Description

Technical Field

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

[0002] Pollination is a key step in wheat hybrid breeding, including the main step of breeding pollination. After removing the immature stamens in the maternal wheat, the pollen of the mature paternal wheat is transferred to each floret of the maternal wheat. During this period, the maternal wheat cannot be disturbed by pollen from other wheat in the outside world. Existing pollen collectors for wheat breeding, such as a wheat pollen collector disclosed in patent CN217694398U, can automatically collect pollen from the paternal wheat, and can also pour the collected paternal wheat pollen onto the maternal wheat, thereby 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 pollen collection is required for the next different variety of paternal wheat, the pollen remaining in the pollen collector will cause the next batch of collected pollen to be interfered by cross infection, thereby affecting the effectiveness of pollination in the entire wheat hybrid breeding. Summary of the invention

[0003] In order to overcome the problem that pollen remaining in the pollen collector will cause the next batch of pollen collected to be cross-infected and interfere, which affects the effectiveness of breeding pollination, the present invention provides a pollen collector for wheat breeding.

DETAILED DESCRIPTION

[0017] The preferred technical solutions of the present invention are described in detail below with reference to the accompanying drawings.

[0018] Example 1: A pollen collector for wheat breeding, such as Figure 1-Figure 9 As shown, it includes a collecting sleeve 1, a dial ring 2, an inner ring 21, a clamping block 22, an internal compression spring 23, a spur gear 24, a ring gear 25, a fixing frame 3 and a blower 4; a plurality of dial rods 11 are provided on the inner wall of the collecting sleeve 1; the collecting sleeve 1 is rotatably connected with the dial ring 2; a mounting portion 202 is provided in the dial ring 2, and the mounting portion 202 is rotatably connected with the inner ring 21; two clamping blocks 22 are slidably connected in the inner ring 21; an internal compression spring 23 is fixedly connected between the two clamping blocks 22 and the inner ring 21, and the two clamping blocks 22 are tightly attached to each other; a spur gear 24 is fixedly connected to the inner ring 21; a fixing frame 3 is fixedly connected to the collecting sleeve 1; a ring gear 25 is fixedly connected to the fixing frame 3; the spur gear 24 meshes with the ring gear 25; a blower 4 is rotatably connected to the fixing frame 3 through a rotating shaft, the blower 4 has a built-in power supply, and in the initial state, the air outlet of the blower 4 is aligned with the upper port of the collecting sleeve 1.

[0019] like Figure 3As shown, all the levers 11 are set to a downward inclined structure. The lever 11 is in an inclined state, which can not only increase the effective contact area between the lever 11 and the father wheat, but also reduce the movement interference caused by the lever 11 to the rotating father wheat; the levers 11 are all made of soft rubber material. When the lever 11 is in continuous contact with the rotating father wheat, the lever 11 made of soft rubber material can reduce the damage caused to the father wheat.

[0020] like Figure 3 As shown, a ring base 12 is fixedly connected to the bottom of the collecting sleeve 1, and an upward protruding structure is provided in the middle of the ring base 12. Correspondingly, a ring base 12 is provided with a ring groove structure surrounding the protruding structure. The ring base 12 is made of rubber material that can be turned inside out.

[0021] The breeding pollination working steps of the pollen collector for wheat breeding of the present invention are as follows: first, the user flips the hair dryer 4 from the fixing frame 3 to the side away from the upper end of the collecting sleeve 1, and then uses two fingers of one hand to rub the two clamping blocks 22 to both sides respectively, and at the same time, the two clamping blocks 22 respectively drive the two internal pressure springs 23 to be compressed, and uses the other hand to pass the male parent wheat downward through the two clamping blocks 22 in the inner ring 21 with the wheat ears facing downward and the wheat stalks facing upward. The male parent wheat used is wheat with complete wheat ears and mature pollen, and the wheat stalks of the male parent wheat are shortened in advance, so that the wheat ears of the male parent wheat are allowed to enter the interior of the collecting sleeve 1 downward. When the wheat stalks of the male parent wheat are located between the two clamping blocks 22, the user loosens the two clamping blocks 22, and the two compressed internal pressure springs 23 drive the two clamping blocks 22 to move toward each other and reset and clamp the wheat stalks of the male parent wheat, so that the wheat ears of the male parent wheat remain in the collecting sleeve 1, and the user then flips the hair dryer 4 and resets it to be aligned with the upper end of the collecting sleeve 1.

[0022] Afterwards, the user sets the lower end of the collecting sleeve 1 on the outside of the wheat ear seeding part of the female wheat, and the annular base 12 is set on the outside of the wheat stalk of the female wheat and keeps the middle part convex upward, and the wheat ear seeding part of the female wheat is kept in the axial area of ​​the collecting sleeve 1. At this time, the wheat ear of the male wheat is adjacent to the wheat ear seeding part of the female wheat, and then the user slowly rotates the dial ring 2 to drive the inner ring 21 and the male wheat clamped by the clamping block 22 to revolve around the wheat ear seeding part of the female wheat. At the same time, when the inner ring 21 drives the spur gear 24 to move along the annular gear 25, the stationary annular gear 25 pinches the rotating spur gear 24 to drive the inner ring 21 and the male wheat clamped by the clamping block 22 to rotate. During the revolution, the male wheat continuously collides with the dial rods 11 in various areas of the collecting sleeve 1 through rotation. In this process, the male wheat on During the continuous collision process, the pollen is continuously and evenly scattered around the seeding part of the wheat ear of the mother wheat, so that the pollen is evenly scattered on the seeding part of the wheat ear of the mother wheat, and most of the pollen that has not effectively fallen on the seeding part of the wheat ear of the mother wheat will fall into the annular groove structure of the annular base 12. Then the user turns on the low speed gear of the hair dryer 4, and the hair dryer 4 continuously blows a low-speed airflow from top to bottom toward the inside of the collecting sleeve 1. The low-speed airflow continuously blows the pollen that has fallen into the annular groove structure of the annular base 12 upward again, so that the pollen continuously circulates in various areas inside the collecting sleeve 1, which not only avoids a large amount of pollen from floating outward in the air and interfering with the rest of the mother wheat around, but also improves the acceptance effect of the wheat ear seeding part of the mother wheat located inside the collecting sleeve 1 on the pollen, thereby improving the breeding pollination efficiency of the mother wheat.

[0023] It should be noted that in nature, wheat itself mainly spreads pollen through wind and insects, and the stigma of wheat pistil is loose and feathery, which can prevent the pollen in contact with it from being disturbed by airflow. Therefore, there is no need to worry about the low-speed airflow blown by the hair dryer 4 affecting the pollinated wheat.

[0024] The steps of cleaning the residual pollen in the collecting sleeve 1 of the pollen collector for wheat breeding of the present invention are as follows: after finishing the breeding pollination work of the female wheat, the user removes the collecting sleeve 1 from the female wheat and removes the male wheat from the clamping block 22, and then puts the lower end of the collecting sleeve 1 into a portable bucket filled with pure water, and then the user turns the middle area of ​​the annular base 12 outward from the inside of the collecting sleeve 1, as shown in FIG. Fig. 9As shown, at this time, there is no annular groove structure in the annular base 12, and 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 airflow from top to bottom toward the inside of the collecting sleeve 1, and the high-speed airflow continuously blows the pollen remaining on the inner wall of the collecting sleeve 1 and the lever 11 downward into the carried bucket, and the blown pollen is collected by the pure water in the carried bucket, thereby completing the cleaning of the residual pollen in the collecting sleeve 1.

[0025] Example 2: Figure 1-Figure 7 As shown, the difference between this embodiment and embodiment 1 is that a cavity structure is provided in the fixing frame 3; a liquid storage bag 5 is fixedly connected to the fixing frame 3, and the liquid storage bag 5 contains cleaning liquid; two infusion tubes 51 are commonly connected between the liquid storage bag 5 and the cavity structure of the fixing frame 3; a plurality of liquid spray heads 301 connected to the cavity structure are provided on the fixing frame 3, and the outlet ends of the liquid spray heads 301 are all located above the ring gear 25; all the liquid spray heads 301 are arranged to be inclined downwardly toward the collecting sleeve 1; the hair dryer 4 has an airflow heater built in; and a plurality of inclined plates 26 are fixedly connected to the dial ring 2.

[0026] When the user turns on the hair dryer 4 to clean the residual pollen in the collecting sleeve 1, the user slowly presses the liquid storage capsule 5 with one hand to allow the cleaning liquid in the liquid storage capsule 5 to enter the cavity structure of the fixing frame 3 through the infusion tube 51, and the cleaning liquid is then sprayed to the lower part of the collecting sleeve 1 through the various spray heads 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 spray head 301 to various areas at the lower part of the collecting sleeve 1, so that the cleaning liquid can efficiently spray and clean various areas of the inner wall of the collecting sleeve 1 and all surfaces of the lever 11, further improving the cleaning efficiency of the residual pollen in the collecting sleeve 1. After stopping squeezing the liquid storage capsule 5, the user ends the spray cleaning treatment on the surface of the lever 11, and then the user turns on the airflow heater of the hair dryer 4 to allow the hair dryer 4 to continuously blow hot air into the collecting sleeve 1, so that the inner wall of the collecting sleeve 1 and the surface of the lever 11 are quickly dried.

[0027] Example 3: Figure 1-Figure 8 As shown, the difference between this embodiment and embodiment 1 is that a clamping assembly is provided on the collecting sleeve 1 of this embodiment; a bag 7 is clamped on the clamping assembly; an opening is respectively provided on the upper and lower sides of the bag 7, the clamping assembly is clamped at the upper opening of the bag 7, and the middle part of the upper opening of the clamping assembly is sleeved on the outer surface of the collecting sleeve 1; a layer of adhesive layer is respectively provided at the openings on both sides of the bag 7; the clamping assembly consists of a fixed splint 61, a movable splint 62 and an external compression spring 63; two fixed splints 61 are fixedly connected to the collecting sleeve 1; a movable splint 62 is slidably connected between the two fixed splints 61; an external compression spring 63 is respectively fixedly connected between the two fixed splints 61 and the movable splint 62.

[0028] The user pushes the clamping part of the movable clamping plate 62 to control the two movable clamping plates 62 to cooperate with the fixed clamping plate 61 to clamp the left and right sides of the upper opening of the bag 7 respectively. Then, according to the above steps, the male wheat is placed in the collecting sleeve 1 and clamped between the two clamping blocks 22. At the same time, the lower opening of the bag 7 is sleeved on the outside of the wheat ear planting part of the female wheat, and the adhesive layer of the lower opening of the bag 7 is used to pinch the lower opening together, so that the lower opening of the bag 7 remains sleeved on the outside of the wheat ear planting part of the female wheat and is in a closed state. At this time, the wheat ear planting parts of the male wheat and the female wheat in the collecting sleeve 1 are both located in the bag 7, so that in the subsequent breeding pollination work, the pollen falling from the collecting sleeve 1 to the outside will remain in the bag 7 and will not spread to the external environment.

[0029] After finishing the breeding pollination work, the user removes the collecting sleeve 1 and the clamping assembly from the bag 7, and promptly uses the adhesive layer of the upper opening of the bag 7 to pinch the upper opening together to prevent pollen in the external environment from entering the bag 7 and contacting the planting part of the wheat ear of the mother wheat, thereby ensuring the effectiveness of breeding pollination to prevent external infection during the breeding pollination work.
