Description

Technical Field

[0001] This utility model relates to the field of crop pest and disease control technology, specifically to a long-lasting slow-release packaging device for predatory mites. Background Technology

[0002] Predatory mites are beneficial mites that prey on harmful mites. They are widely distributed and can be found on leaves with high concentrations of harmful mites. Predatory mites are characterized by their short development cycle, which lasts only 5-7 days at 25-28℃, about half the time of common harmful mites. This is beneficial for controlling harmful mites. Predatory mites can control adult and nymphal mites as well as small pests such as thrips and whiteflies. They are widely used in the production of pollution-free vegetables and fruits.

[0003] In past practical applications of predatory mites for pest control, they were typically released using two packaging methods: plastic bottles filled with sawdust and hanging bags filled with sawdust. Plastic bottles are prone to shaking, which is detrimental to the survival of predatory mites during transport; they also require manual sowing onto plants to ensure even distribution, a demanding and time-consuming process. Hanging bags are susceptible to external pressure, not moisture-proof, and require specialized packaging machines for filling and cutting; they are unsuitable for soft plant leaves like strawberries, as they break easily, and are only suitable for hard branches like fruit trees. Furthermore, once the bags are opened, rainwater can enter, causing the predatory mites to drown inside. Both methods use sawdust as the packaging medium, which is prone to moisture and mold, causing environmental pollution when scattered in farmland and greenhouses, affecting aesthetics, being unrecyclable, and posing fire hazards; the excessively curled sawdust makes it difficult for predatory mites to find an exit quickly. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the main objective of this invention is to provide a packaging device for the automatic release of predatory mites, saving time and effort for long-term, slow-release of predatory mites.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A long-lasting slow-release packaging device for predatory mites includes a box body with a release port, and the box body has a moisture-absorbing and heat-insulating layer and a packaging medium layer arranged sequentially from bottom to top inside the box body.

[0007] Preferably, the moisture-absorbing and heat-insulating layer is composed of a moisture-proof and moisture-absorbing agent, the packaging medium layer includes polyurethane foam and a mesh bag, the polyurethane foam is fitted inside the mesh bag, the upper end of the mesh bag is open, and the open end of the mesh bag can extend to a release port.

[0008] Preferably, the release port is provided with a zipper, and the release port is closed and opened by the zipper.

[0009] Preferably, each side of the box body is provided with a release port, and a zipper is provided at the release port, which is closed and opened by the zipper.

[0010] In another embodiment, the moisture-absorbing agent is one or more of silica gel particles, silica gel-salt composite moisture absorber, or polymer-salt composite moisture absorber, and the packaging medium layer is composed of polyurethane foam.

[0011] Preferably, it further includes a zippered mesh bag, which is fixed to the outer surface of the release port and has an opening at the top. The opening of the zippered mesh bag is closed and opened by a zipper, and the zippered mesh bag is inserted back into the upper surface of the packaging medium layer through the release port.

[0012] Preferably, the zippered mesh bag is fixed to the outer surface of the box or embedded in the outer surface of the box.

[0013] Preferably, the side of the box is provided with a breathable mesh, and a concealed zipper tape is installed at the edge of the breathable mesh.

[0014] Preferably, the thickness of the moisture-absorbing and heat-insulating layer is 0.5-1.5cm, and the thickness of the packaging medium layer is 4-15cm.

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] 1) The long-lasting slow-release packaging device for predatory mites provided in this application includes a box body with a release port on the box body. The box body is provided with a moisture-absorbing and heat-insulating layer and a packaging medium layer from bottom to top. By providing a moisture-absorbing and heat-insulating layer at the bottom of the box body, the packaging device can inhibit the growth of miscellaneous bacteria while maintaining a certain humidity. The packaging medium layer is provided inside the box body, which can serve as a habitat for predatory mites. In actual use, the packaging device is placed next to a plant, and the predatory mites in the packaging medium layer can be automatically released through the release port on the box body, which is convenient and practical.

[0017] 2) This application employs a moisture-absorbing and heat-insulating layer with a moisture-proof absorbent agent and a packaging medium layer with polyurethane foam. Compared to the previous method of using wood chips as the packaging medium, polyurethane foam is less prone to moisture absorption and mold growth, effectively achieving dehumidification and moisture prevention in the packaging device. In addition, the use of a moisture-proof absorbent agent further dehumidifies and prevents mold growth, ensuring a certain level of humidity inside the box while preventing the growth of miscellaneous bacteria. Furthermore, the soft and elastic polyurethane foam has high porosity and is not prone to moisture absorption and mold growth, preventing the shaking of the box contents during transportation from compressing predatory mites and providing them with physical living space, significantly improving their survival rate during transportation. At the same time, the design that allows for the addition of food for predatory mites can further extend their survival time, thereby extending their service life.

[0018] 3) This application features a zipper at the release port, which can be closed and opened. During agricultural operations such as spraying pesticides, the slow-release net can be tucked back in to close the opening, turning the box into a shelter and protecting the predatory mites inside from pesticide poisoning. This effectively improves the survival rate of the predatory mites and allows the packaging device to be used in greenhouses where pesticides are sprayed. Furthermore, the zipper design allows for easy adjustment of the zipper opening size, effectively controlling the slow-release density of the predatory mites.

[0019] 4) The packaging device provided in this application is reusable. After the predatory mites are released from the box, they can be refilled and reused. In addition to predatory mites, the packaging device can also carry Beauveria bassiana for joint control, with Beauveria bassiana powder adhering to the predatory mites. Attached Figure Description

[0029] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.

[0030] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] In the following embodiments, the moisture-absorbing agent used is one or more of silica gel particles, silica gel-salt composite moisture absorbers, or polymer-salt composite moisture absorbers. Silica gel particles, silica gel-salt composite moisture absorbers, and polymer-salt composite moisture absorbers can all be purchased commercially. Silica gel-salt composite moisture absorbers are composed of silica gel and hygroscopic salts (such as magnesium chloride or lithium chloride) in a mass ratio of 2:1, and their water absorption capacity is generally superior to pure silica gel. Polymer-salt composite moisture absorbers are composed of a high molecular weight polymer (sodium polyacrylate type water-absorbing resin or acrylate type water-absorbing resin) and a hygroscopic salt (such as magnesium chloride or lithium chloride) in a mass ratio of 1:1, combining the structural stability of the polymer with the hygroscopic properties of the salt.

[0032] Example 1

[0033] like Figure 1 , 2 and Figure 3 As shown, the long-lasting slow-release packaging device for predatory mites provided in this embodiment includes a box body 1, which has dimensions of 15cm x 15cm x 15cm. A release port 2 is provided on the box body 1. Inside the box body 2, from bottom to top, a moisture-absorbing and heat-insulating layer 3 and a packaging medium layer 4 are sequentially arranged. The thickness of the moisture-absorbing and heat-insulating layer 3 is 0.5-1.5cm, further up to 1cm; the thickness of the packaging medium layer 4 is 4-15cm, further up to 14cm. Specifically, by setting the moisture-absorbing and heat-insulating layer at the bottom of the box body, the packaging device inhibits the growth of miscellaneous bacteria while maintaining a certain level of humidity. Furthermore, the packaging medium layer inside the box serves as a habitat for the predatory mites. In use, the packaging device is placed next to a plant, and the predatory mites in the packaging medium layer are automatically released through the release port on the box body, making it convenient and practical.

[0034] Example 2

[0035] Refer again Figure 1 , Figure 2 and Figure 3Based on the embodiment, the moisture-absorbing and heat-insulating layer 3 in the box body 1 is composed of silicone particles, and the packaging medium layer 4 includes polyurethane foam 41 and a mesh bag 42; a layer of silicone particles is laid at the bottom of the box body as a moisture-absorbing and heat-insulating layer to absorb moisture and prevent mold; a small piece of polyurethane foam 41 is wrapped in a mesh bag 42, which can act as a cushion to reduce internal shaking and provide a shelter for predatory mites. The mesh bag 42 also serves as a release medium for predatory mites, allowing them to crawl onto plant leaves, etc., through the mesh bag with the extended release port; the polyurethane foam 41 is fitted in the mesh bag 42, the upper end of the mesh bag 42 is open, and the open end of the mesh bag 42 can extend to the release port 2, where a zipper 5 is provided, and the release port 2 is closed and opened by the zipper 5. For specific packaging, first evenly sprinkle silicone granules at the bottom of the box. Then, stuff some small pieces of polyurethane foam into the mesh bag and place it inside the box, on the surface of the moisture-absorbing and heat-insulating layer made of silicone granules. Next, sprinkle an appropriate amount of predatory mites and predatory mite food on the polyurethane foam. After the predatory mites have evenly covered the polyurethane foam, continue to fill the box with small pieces of polyurethane foam until the entire box is filled. Then, tie the mesh bag tightly with a cable tie and tuck the open end of the mesh bag near the zippered release port for easy removal. Finally, seal the box, and it is ready for transportation and use.

[0036] In a preferred embodiment, the sides of the box are provided with release ports, and zippers are provided at the release ports. The release ports are closed and opened by the zippers. The packaging device can controllably release predatory mites through the zippers provided on the sides of the box, which is convenient and practical.

[0037] In practical use, the mesh bag, while encasing small pieces of polyurethane foam, also acts as a dispersal corridor for predatory mites by utilizing their tendency to move upwards. To use, simply open the zipper, untie the tie, pull the mesh bag out from the release port, and drape it over the plant to release the predatory mites.

[0038] Meanwhile, when spraying pesticides, tie the mesh bag tightly and plug it back into the box through the release port, then zip it up. When the pesticide level is below the safety line, open it again and repeat the above steps. This acts as a "shelter" and effectively improves the survival rate of predatory mites, allowing this packaging device to be used in greenhouses where pesticides are sprayed.

[0039] Example 3

[0040] like Figure 4 and Figure 5As shown, based on Example 1, the moisture-absorbing and heat-insulating layer 3 in the box 1 is composed of silicone particles, and the packaging medium layer 4 is composed of small pieces of polyurethane foam. The silicone particles can dehumidify and prevent mold, ensuring a certain humidity level inside the box 1 while preventing the growth of bacteria; while the polyurethane foam is soft, elastic, and has high porosity, preventing the shaking of the box contents during transportation from squeezing predatory mites, providing a physical living space for the predatory mites, and significantly improving the survival rate of predatory mites during transportation.

[0041] In a preferred embodiment, the package further includes a zippered mesh bag 6, which is fixed to the outer surface of the release port 2. The zippered mesh bag 6 is fixed to the outer surface of the box body 1, or embedded within the outer surface of the box body 1. The zippered mesh bag 6 has an opening at its top, which is closed and opened via a zipper. The zippered mesh bag 6 is then inserted back into the upper surface of the packaging medium layer 4 through the release port 2. Specifically, during packaging, silicone granules are first evenly sprinkled at the bottom of the box body. Then, small pieces of polyurethane foam are inserted into the mesh bag through the release port and placed inside the box body on the moisture-absorbing and heat-insulating layer composed of silicone granules. Next, an appropriate amount of predatory mites and their food are sprinkled onto the polyurethane foam. After the predatory mites have evenly covered the polyurethane foam, small pieces of polyurethane foam are continued to be added until the entire box body is filled. The zippered mesh bag is then inserted into the box body through the release port for easy removal, after which it can be transported and used.

[0042] In practical use, place this packaging device on the planting trough, unzip the mesh bag, and adjust the size of the zipper opening according to the severity of the pests and diseases, thereby adjusting the size of the release port. Then, drape the mesh bag over the plant leaves, stems, or planting trough, and the predatory mites will automatically and slowly crawl out.

[0043] In another preferred embodiment, the side of the box is provided with a breathable mesh, and a concealed zipper is installed at the edge of the breathable mesh. In actual use, the zipper straps on the side can be opened or closed according to the actual needs. For example, in daily prevention and control, only the zipper straps on the side need to be opened. When pests and diseases are severe, all zipper bags (openings) can be opened to the maximum extent. This setting provides technical support for the convenience and practicality of the packaging device.

[0044] The predatory mite long-release packaging device provided in this application is particularly suitable for plants such as strawberries.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
