Description

Technical Field

[0001] The invention relates to the technical field of vegetable and fruit hybridization, in particular to a pollen collection and rapid emasculation device. Background Art

[0002] The maturation time of male and female flowers of leek is inconsistent, so in the hybridization work, it is necessary to collect pollen and remove stamens when the male flowers mature. At the same time, due to the characteristics of leek parthenogenesis, a lot of hybridization work is often required to select true hybrid offspring. In the conventional leek hybridization work, it is necessary to manually use tweezers to perform these two tasks, which consumes a lot of manpower and material resources. In the process of using tweezers to remove pollen, it is easy to cause the anther to rupture, resulting in incomplete pollen removal. At present, although there are many devices that can be used alone for pollen collection and emasculation, there is still no device that can combine the two tasks into one.

[0003] The problems existing in the prior art are as follows: 1. Compared with professional pollen collection devices, pollen will be sucked together with anthers when collecting pollen, and it needs to be manually screened out later. 2. When collecting pollen of multiple varieties, in order to ensure the purity of the pollen, the pollen suction head and storage capsule need to be replaced or cleaned in time, which is still inconvenient in use.

[0025] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Embodiment, this embodiment provides a pollen collection and rapid emasculation device, such as Figure 1 As shown, the housing includes an upper housing 1 and a lower housing 11. An installation chamber is provided between the upper housing 1 and the lower housing 11, and the upper housing 1 and the lower housing 11 are detachably connected. The corners of the upper housing 1 and the lower housing 11 are connected by snaps or bolts. At the same time, a hanging buckle 12 is rotatably provided on the outer wall of the upper housing 1. The hanging buckle 12 can be lifted by one hand for easy carrying during operation.

[0027] like Figure 1 and Figure 4 As shown, a vacuum pump 9 is installed in the installation chamber, and a lithium battery 10 is also installed in the installation chamber. The positive and negative electrodes of the lithium battery 10 are connected to the terminal of the vacuum pump 9 through a wire; the surface wall of the upper shell 1 is also rotatably installed with an adjustment knob 4 for controlling the gear of the vacuum pump 9. The gear of the vacuum pump 9 is adjusted by adjusting the knob 4, thereby controlling the magnitude of the negative pressure suction force. At the same time, the positive and negative electrodes of the lithium battery 10 are also connected to a charging connector 5 through a wire, and the charging connector 5 is embedded in the outer wall of the upper shell 1. The charger plug is inserted into the charging connector 5 to supply power to the lithium battery 10 to meet the power supply demand of the vacuum pump 9. Fold = The overall structure is compact and light and is equipped with a battery, which is convenient for hybrid workers to carry with them to the fields at any time to carry out work.

[0028] At the same time Figure 4 As shown, the vacuum pump 9 has an air inlet 2 and an air outlet 3, the air inlet 2 is connected to an air inlet connector embedded in the surface wall of the upper shell 1, the air outlet 3 is connected to an air outlet connector embedded in the surface wall of the upper shell 1, and the end of the air inlet connector is detachably connected to an extension hose 6, and the inner diameter of one end of the extension hose 6 connected to the air inlet connector is smaller than the outer diameter of the end of the air inlet connector. In this way, the extension hose 6 adopts a rubber hose, and when the extension hose 6 is connected to the large-diameter air inlet connector with a small inner diameter, the air inlet connector expands the inner wall of the end of the extension hose 6, which can achieve docking on the one hand and prevent it from falling off at will on the other hand.

[0029] At the same time, a pollen storage capsule 7 is detachably connected to the end of the extension hose 6, and the outer diameter of the end of the pollen storage capsule 7 is larger than the inner diameter of the end of the extension hose 6. In this way, when the pollen storage capsule 7 is plugged into the inner wall of the end of the extension hose 6, it will not fall off at will. A suction head 8 is threadedly connected to the end of the pollen storage capsule 7, and the end of the suction head 8 is a reduced opening structure. A filter membrane 71 is built into the inner wall of one end of the pollen storage capsule 7 away from the suction head 8. The filter membrane 71 here is a PTFE (polytetrafluoroethylene) membrane, which is a typical hydrophobic membrane commonly used in air filtration. It has excellent chemical stability and thermal stability, and can resist the erosion of various chemical substances.

[0030] It should be further explained that the diameter of the reduced opening structure of the suction head 8 is 1mm, 2mm or 3mm, the diameter of the other end of the suction head 8 is 1cm and the length is 5cm; the suction head 8 is threadedly connected to the pollen storage capsule 7 and can be rotated and removed. Equipped with replaceable suction heads 8 of different sizes, it can be used in the hybridization of various vegetables and fruits, including leeks, grapes, and blueberries. At the same time, the pollen storage capsule 7 is a hollow cylindrical structure with a diameter of 1cm and a length of 15cm. According to needs, multiple pollen storage capsules 7 are selected, and different types of pollen can be stored by replacing the pollen storage capsules 7 during use.

[0031] like Figure 2 and Figure 3 As shown, a suction head 8 of a suitable size can be connected to the pollen storage capsule 7 according to the size of the anthers of different vegetables and fruits, and then connected to the air inlet joint through the extension hose 6, and the vacuum pump 9 is turned on at the same time, and the suction head 8 is brought close to the anthers to suck the anthers and pollen into the pollen storage capsule 7. Here, a filter membrane 71 is built into the inner wall of the end of the pollen storage capsule 7 away from the suction head 8, and the filter membrane 71 only allows air to pass through, while the pollen is stored in the pollen storage capsule 7, that is, the two processes of rapid emasculation and pollen collection are completed. Compared with manual work, the success rate of emasculation and the efficiency of pollen collection are greatly improved.

[0032] Afterwards, when enough pollen is collected, the suction head 8 is screwed off and the pollen in the pollen storage sac 7 is poured out for storage.

[0033] In summary, rapid emasculation of floral organs and pollen collection can be performed simultaneously, which greatly improves the efficiency of hybridization and reduces the investment in manpower and time.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
