Description

Technical Field

[0001] This invention relates to a breeding bag for improving the survival rate of orchid hybridization, and belongs to the field of breeding bag technology. Background Technology

[0002] Orchid hybridization breeding is a key method for cultivating new varieties. Its core steps involve artificial pollination followed by isolation and protection of the mother plant's flowers to prevent contamination from foreign pollen, and maintaining a suitable microenvironment (humidity 60%-80%, temperature 15-28℃) to promote fertilization and fruit set. In traditional breeding processes, two main types of breeding bags are commonly used: paper breeding bags and plastic film bags.

[0003] However, existing paper breeding bags are made of kraft paper or tracing paper, and the bag opening is tied with cotton thread, which has poor sealing (making it easy for bacteria and foreign pollen to enter). They are also highly absorbent, resulting in large humidity fluctuations. Plastic film bags are made of transparent polyethylene, with an elastic rope at the bag opening, which has extremely poor air permeability and easily forms condensation (humidity inside the bag ≥95%), leading to stigma rot or pollen tube growth being hindered. There is an urgent need for a breeding bag that can improve the survival rate of orchid hybridization to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a breeding bag that improves the survival rate of orchid hybridization, so as to solve the problems mentioned in the background technology. This utility model breaks through the contradiction between the sealing and air permeability of traditional breeding bags through the innovative design of "composite material + intelligent moisture retention + environmental adaptation", and significantly improves the survival rate of orchid hybridization.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a breeding bag for improving the survival rate of orchid hybridization, comprising a composite bag body and an annular limiting seat. The composite bag body is provided with a sunshade. The composite bag body is composed of an ultraviolet-resistant polyethylene film, a polytetrafluoroethylene breathable film, and a non-woven fabric lining from the outside to the inside. An annular limiting seat is horizontally adhered to the upper edge of the non-woven fabric lining. An annular moisturizing cotton is placed inside the annular limiting seat. One-way exhaust valves are fixed through the middle of the left and right ends of the ultraviolet-resistant polyethylene film, the polytetrafluoroethylene breathable film, and the non-woven fabric lining. An embedding opening is provided at the lower left end of the ultraviolet-resistant polyethylene film, the polytetrafluoroethylene breathable film, and the non-woven fabric lining, and a humidity indicator strip is adhered at the embedding opening. A miniature humidity sensor is embedded at the lower left end of the ultraviolet-resistant polyethylene film, the polytetrafluoroethylene breathable film, and the non-woven fabric lining. The lower end of the composite bag body is provided with a bag opening, and an elastic silicone ring is sewn to the lower end of the bag opening.

[0006] Furthermore, a plastic tube is glued to the middle of the upper end of the composite bag body, and a plastic protrusion is glued to the lower end of the sunshade, with the plastic protrusion damping and snapping into the plastic tube.

[0007] Furthermore, the UV-resistant polyethylene film, the polytetrafluoroethylene breathable film, and the non-woven fabric lining are all provided with micro water passages at their left and right ends, and both of the micro water passages are connected to the left and right sides inside the annular limiting seat.

[0008] Furthermore, both of the aforementioned miniature water pipes are plugged with rubber stoppers on their outer sides.

[0009] Furthermore, the lower end of the annular limiting seat is provided with an annular through groove, and breathable cotton is sewn into the annular through groove.

[0010] Furthermore, a nylon cable tie is fitted over the outside of the bag opening.

[0011] The beneficial effects of this utility model: This utility model provides a breeding bag for improving the survival rate of orchid hybridization. Because it incorporates a composite bag body, UV-resistant polyethylene film, polytetrafluoroethylene breathable film, non-woven fabric lining, rubber stopper, miniature water pipe, annular limiting seat, annular moisturizing cotton, breathable cotton, one-way exhaust valve, humidity indicator strip, miniature humidity sensor, elastic silicone ring, and nylon cable ties, its structure is reasonable. Through the innovative design of "composite materials + intelligent moisturizing + environmental adaptation," it overcomes the contradiction between the sealing and breathability of traditional breeding bags, significantly improving the survival rate of orchid hybridization. It is especially suitable for hybridization breeding of rare orchid varieties, possessing high practical value and promising prospects for promotion, and is highly practical.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3 This utility model provides a technical solution: a breeding bag for improving the survival rate of orchid hybridization, comprising a composite bag body 2 and an annular limiting seat 5. A sunshade 1 is provided above the composite bag body 2. The composite bag body 2 is composed of an ultraviolet-resistant polyethylene film 21, a polytetrafluoroethylene breathable film 22, and a non-woven fabric lining 23 from the outside to the inside. The annular limiting seat 5 is horizontally adhered to the upper edge of the non-woven fabric lining 23. An annular moisture-retaining cotton 6 is placed inside the annular limiting seat 5. One-way exhaust valves 8 are fixed through the middle of the left and right ends of the ultraviolet-resistant polyethylene film 21, the polytetrafluoroethylene breathable film 22, and the non-woven fabric lining 23. An embedding opening is provided at the lower left end of the polytetrafluoroethylene breathable membrane 22 and the non-woven fabric lining 23, and a humidity indicator strip 9 is affixed to the embedding opening. A miniature humidity sensor 10 is embedded at the lower left end of the UV-resistant polyethylene film 21, the polytetrafluoroethylene breathable membrane 22, and the non-woven fabric lining 23. The lower end of the composite bag body 2 is provided with a bag opening 11, and an elastic silicone ring 12 is sewn to the lower end of the bag opening 11. This design solves the problems of existing paper breeding bags made of kraft paper or sulfuric acid paper having poor sealing performance, strong water absorption, and large humidity fluctuations, and existing plastic film bags made of transparent polyethylene material with extremely poor air permeability, which easily forms condensation water, leading to stigma rot or pollen tube growth obstruction.

[0019] As the first embodiment of this utility model: a plastic tube is glued to the middle of the upper end of the composite bag body 2, and a plastic protrusion is glued to the lower end of the sunshade 1. The plastic protrusion is damped and inserted into the plastic tube. By adding the plastic protrusion damped and inserted into the plastic tube, the installation of the sunshade 1 can be realized. In the summer when there is strong sunlight, the sunshade 1 can reduce the temperature rise inside the bag.

[0020] The UV-resistant polyethylene film 21, the polytetrafluoroethylene breathable film 22, and the non-woven fabric lining 23 are all equipped with micro water passages 4 at their left and right ends. Both micro water passages 4 are connected to the left and right sides of the annular limiting seat 5. The added UV-resistant polyethylene film 21 has a thickness of 0.08mm and a light transmittance of 70%, which can avoid direct sunlight and block 90% of ultraviolet rays, effectively preventing high temperatures inside the bag. The polytetrafluoroethylene breathable film 22 has a pore size of 0.22μm, which allows gas exchange but blocks pollen and bacteria, effectively achieving gas exchange with a breathability of 50-100ml / min and preventing pollution. The non-woven fabric lining 23 can absorb water and dry quickly, preventing condensation from directly contacting the orchid flowers and keeping the orchid flowers dry.

[0021] Both micro-water passages 4 are plugged with rubber stoppers 3. These stoppers block the passages, allowing breeders to add water to the annular retaining seat 5 via the micro-water passages 4 when the humidity of the annular moisture-retaining cotton 6 is low. The water is then absorbed by the annular moisture-retaining cotton 6, which contains 0.5g of superabsorbent resin with a saturated absorption capacity of 5ml. An annular groove is located at the lower end of the annular retaining seat 5, and breathable cotton 7 is sewn into this groove. This breathable cotton 7 helps the annular moisture-retaining cotton 6 slowly release moisture, maintaining a humidity of 60%-80% inside the composite bag 2. A nylon cable tie 13 is fitted over the bag opening 11, allowing for adjustable fit to prevent the bag opening from loosening when placed over the flower stem.

[0022] As a second embodiment of this utility model: After artificially pollinating the orchid flowers, the composite bag 2 is placed over the top of the flower, ensuring that the flower is completely centered inside the bag (without touching the bag wall); then, the elastic silicone ring 12 is adjusted to fit the flower stem, and the nylon cable tie 13 is tightened to a moderate tightness (preferably without shaking and without deformation of the flower stem), and the nylon cable tie 13 is fastened. If the micro humidity sensor 10 detects that the initial ambient humidity inside the bag is ≤50%, water is added to the annular limiting seat 5 through two micro water channels 4 using an external syringe so that it can be absorbed by the annular moisturizing cotton 6, until 3ml of clean water is injected (high). (Water-absorbing resin saturated); if humidity ≥ 70%, do not add water; daily monitoring is done via the outer humidity indicator strip 9. When the humidity indicator strip 9 turns blue (humidity < 60%), add 1ml of water; when it turns red (humidity > 80%), open the two one-way exhaust valves 8 to accelerate ventilation. In summer with strong sunlight, insert the plastic protrusion damping clip into the plastic tube to achieve the installation of the sunshade 1 and reduce the temperature rise inside the bag; before heavy rain, check whether the two one-way exhaust valves 8 are closed to prevent rainwater backflow. The UV-resistant polyethylene film 21 has a thickness of 0.08mm and a light transmittance of 70%, which can avoid direct sunlight and block 90% of strong light. Ultraviolet light effectively prevents high temperatures inside the bag. The PTFE breathable membrane 22 has a pore size of 0.22μm, allowing gas exchange while blocking pollen and bacteria, effectively achieving gas exchange with a breathability of 50-100ml / min and preventing pollution. The non-woven fabric lining 23 is absorbent and quick-drying, preventing condensation from directly contacting the orchid flowers and keeping them dry, thereby improving the survival rate of orchid hybridization.
