Description

Technical Field

[0001] This utility model relates to the field of pollen isolation devices, and more specifically, to a pollen isolation device for chili pepper breeding. Background Technology

[0002] In chili pepper breeding, pollen isolation is crucial for ensuring varietal purity and achieving breeding goals. Natural pollination pathways such as insects and wind can easily lead to non-target hybridization. As a cross-pollinated crop, chili peppers have a natural cross-pollination rate of approximately 10%-30%, which can result in segregation of offspring traits and may also cause genetic contamination of superior inbred lines, affecting breeding efficiency and seed purity.

[0003] Traditional isolation devices have shortcomings in artificial pollination operations. Most of them use simple mesh bags or rope tying to fix the plants. This fixing method lacks flexibility. Rope tying can easily damage the plant stems and is difficult to adapt to changes in the thickness of the plant stems at different growth stages. Moreover, the length of the isolation cover is fixed and cannot match the changes in plant height from the seedling stage to the flowering stage. Often, the cover will squeeze the flowers and affect the plant growth.

[0004] In addition, traditional isolation devices lack versatility, as they are mostly designed for single use or a single specification and cannot be reused for breeding work of different varieties or batches, resulting in waste of resources and increased breeding costs. Utility Model Content

[0005] The purpose of this invention is to provide a pollen isolation device for chili pepper breeding, in order to solve the technical problems existing in the background art.

[0006] This utility model provides a pollen isolation device for chili breeding, including an isolation cover and a closing device integrally formed with the isolation cover. The isolation cover includes an upper support ring, a lower support ring, and a mesh cover fixed to the upper support ring and the lower support ring.

[0007] The closing device includes a closing mesh integrated with the mesh cover and an elastic closing ring located at the opening of the closing mesh. In its natural state, the diameter of the closing ring is smaller than the diameter of the lower support ring. The lower support ring is provided with a limiting structure. When the closing ring is put on, it is placed on the limiting structure. When closing, the closing ring is disengaged from the limiting structure.

[0008] In a preferred embodiment, the limiting structure includes an annular groove disposed in the middle of the lower support ring for fitting the closing ring.

[0009] In a preferred embodiment, the lower support ring is provided with four hooks in a circumferential direction, and the closing ring is provided with four corresponding hanging straps.

[0010] In a preferred embodiment, adjustment components for adjusting the length of the isolation cover are also provided on both sides of the isolation cover.

[0011] In a preferred embodiment, the adjustment component includes a fixed belt and a movable belt corresponding to the fixed belt. The fixed belt is provided with a protruding structure, and the movable belt is provided with a plurality of fixing holes along the length direction of the movable belt.

[0012] The beneficial effects of this utility model's technical solution are:

[0013] This design uses upper and lower support rings and a mesh cover to form a closed space, effectively preventing insects and wind from spreading foreign pollen, providing a pure environment for artificial pollination and ensuring the accuracy of breeding genes. The elastic closing ring and limiting structure in the sealing device allow for quick assembly, disassembly, and sealing of the isolation cover, avoiding damage to the plant caused by traditional rope binding. It also allows for flexible opening and closing during artificial pollination, improving operational efficiency. The adjustable components allow for stretching or shrinking of the isolation cover's length to adapt to changes in plant height throughout its life cycle, preventing flower compression. Furthermore, the device is reusable, reducing costs and improving resource utilization. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] like Figures 1-3As shown, this utility model provides a pollen isolation device for chili pepper breeding, including an isolation cover 1 and a sealing device 6 integrally formed with the isolation cover 1. The isolation cover 1 is placed over the chili pepper plant, and the sealing device 6 is used to seal the bottom of the isolation device to ensure airtightness.

[0020] The isolation cover 1 includes an upper support ring 2, a lower support ring 3, and a mesh cover 4 fixed to the upper support ring 2 and the lower support ring 3. The upper support ring 2 and the lower support ring 3 form a three-dimensional frame through a rigid structure, such as a metal ring. The mesh cover 4 (such as nylon mesh) covers the frame to form a closed space, using the principle of physical barrier to prevent the spread of foreign pollen by insects, wind, etc.

[0021] The closing device 6 includes a closing mesh 7 integrally formed with the mesh cover 4 and an elastic closing ring 8 located at the opening of the closing mesh 7. In its natural state, the diameter of the closing ring 8 is smaller than the diameter of the lower support ring 3. The lower support ring 3 is provided with a limiting structure. When the closing ring is fitted, it is fitted at the limiting structure. When closing, the closing ring 8 is disengaged from the limiting structure.

[0022] In the above scheme, the diameter of the elastic closing ring 8 is small, so that the lower end of the isolation cover 1 fits the stem of the chili plant. When putting it on, in order not to damage the plant, the closing ring 8 is supported by a limiting mechanism, so that the diameter of the closing ring 8 is increased, making it easier to put on the isolation cover 1. After it is put on, the closing ring 8 is removed from the limiting structure, and the closing ring 8 automatically returns to its original diameter, automatically completing the closing.

[0023] The limiting structure includes an annular groove 5 located in the middle of the lower support ring 3 for fitting the closing ring 8. The annular groove 5 provides an annular limiting track. After the elastic closing ring 8 is fitted into the groove, it is secured in the groove by its own elasticity, forming a uniform circumferential fixing force to prevent the closing ring 8 from shifting or falling off.

[0024] The lower support ring 3 has four hooks 9 arranged in a circumferential direction, and the closing ring 8 has four corresponding hanging straps 10. When performing operations such as pollination, the isolation cover 1 needs to be removed. At this time, the four hanging straps 10 are first hung on the corresponding hooks 9 to initially pull the closing ring 8, and then the closing ring 8 is fixed to the annular groove 5. This operation makes the placement of the closing ring 8 smoother. After pollination is completed, the isolation cover is re-placed, and then the closing ring 8 is separated from the annular groove 5, and the opening of the closing ring 8 is tightened.

[0025] The isolation cover 1 is also provided with adjustment components on both sides for adjusting the length of the isolation cover 1. The adjustment components include a fixed strap 11 and a movable strap 12 corresponding to the fixed strap 11. The fixed strap 11 is provided with a protruding structure 13, and the movable strap 12 is provided with a plurality of fixing holes 14 along the length direction of the movable strap 12.

[0026] The fixing strap 11 is fixed to one side of the isolation cover 1, and the movable strap 12 connects to the other side. By inserting the protruding structure 13 into the fixing holes 14 at different positions on the movable strap 12, the longitudinal length of the isolation cover 1 can be stretched or contracted (e.g., adjusted from 30cm to 50cm) to accommodate pepper plants of different heights. The adjustable length design makes the device suitable for the entire growth cycle of peppers (from the seedling stage to the flowering stage, when plant height changes), preventing the top of the isolation cover 1 from squeezing the flowers due to the plant growing taller.

[0027] This design features an isolation cover 1 that forms a closed space through an upper support ring 2, a lower support ring 3, and a mesh cover 4. This physical barrier effectively prevents insects and wind from spreading foreign pollen, providing a pure environment for artificial pollination and ensuring the accuracy of breeding genes. The elastic closing ring 8 in the sealing device 6, in conjunction with the limiting structure, allows for quick assembly, disassembly, and sealing of the isolation cover 1, avoiding damage to the plant caused by traditional rope binding. It also allows for flexible opening and closing during artificial pollination, improving operational efficiency. The adjustable components allow for stretching or contracting the length of the isolation cover 1 to adapt to changes in plant height throughout its life cycle, preventing flower compression. Furthermore, the device is reusable, reducing costs and improving resource utilization.
