Description

Technical Field

[0001] This utility model relates to the field of agricultural mulch film technology, and in particular to a mulch film structure for thrips repellency in cowpea cultivation. Background Technology

[0002] Thrips are a common and highly damaging pest in cowpea cultivation. Despite their small size, they reproduce rapidly, sucking sap from cowpea plants and causing leaf curling, stunted growth, and flower and pod drop, severely impacting yield and quality. Traditional control methods include chemical and physical methods. However, chemical control leaves pesticide residues, affecting cowpea quality and harming the environment and human health. In recent years, plastic film mulching technology has been widely used in agriculture, offering functions such as heat preservation, moisture retention, and fertilizer retention. It has also provided new ideas for thrips control by adding special substances or using special structures to repel thrips. However, this method also has problems. For example, the repellent substances in plastic film containing added natural plant extracts gradually dissipate or decompose over time and with rainwater erosion, weakening the repellent effect and making it difficult to provide sustained and effective protection for cowpea growth. This limits the effectiveness and application scope of this thrips control method. Utility Model Content

[0003] The main objective of this invention is to provide a mulch film mechanism for thrips repellency in cowpea cultivation, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A thrips-repelling mulch film structure for cowpea cultivation includes a base layer. Within the base layer, from bottom to top, a barrier layer, a reinforcing layer, and a buffer layer are fixedly connected in sequence. Edge reinforcing fabric is fixedly connected to the lower left and lower right ends of the base layer. Three rotating ground stakes are movably connected to the upper ends of the two edge reinforcing fabrics. Baffles are fixedly connected to the upper outer surfaces of the six rotating ground stakes, all located above the edge reinforcing fabrics. A repellency release structure is fixedly connected to the upper end of the buffer layer, and a reflective component is fixedly connected to the upper end of the repellency release structure.

[0006] Preferably, the two edge reinforcing fabrics are symmetrically distributed from left to right, and the three longitudinally distributed rotating ground nails are equidistant from each other.

[0007] By adopting the above technical solution, with two edge reinforcing fabrics symmetrically distributed on the left and right and three rotating ground nails equidistantly distributed longitudinally, the stability of the mulch film structure is enhanced and the overall protective effect is improved.

[0008] Preferably, the repellent release structure includes an anti-aging membrane, the lower end of which is fixedly connected to the upper end of a buffer layer, a plurality of repellent capsules are embedded in the upper end of the anti-aging membrane, an upper cover film is disposed directly above the anti-aging membrane, and a plurality of capsule encapsulation grooves are formed at the lower end of the upper cover film.

[0009] By adopting the above technical solution: the anti-aging film is fixedly connected to the buffer layer, and the upper end of the film is inlaid with a repellent capsule. The upper cover film and its capsule encapsulation groove can protect the repellent capsule and reduce its exposure to external influences. At the same time, the anti-aging film extends the structural lifespan, which is conducive to the stable release and continuous effect of the repellent.

[0010] Preferably, the positions of the plurality of repellent capsules and the plurality of capsule encapsulation slots are corresponding and their sizes are matched, the plurality of repellent capsules and the plurality of capsule encapsulation slots are arranged in a rectangular array, the upper end face of the anti-aging film is fixedly connected to the lower end face of the upper covering film, and the plurality of repellent capsules are located between the anti-aging film and the upper covering film.

[0011] By adopting the above technical solution: the position and size of the repellent capsules and the capsule encapsulation grooves are corresponding and distributed in a rectangular array. The anti-aging film and the upper covering film sandwich the repellent capsules in the middle and fix them in place, which helps to store the repellent in an orderly manner and release it stably, while enhancing the stability and durability of the overall structure.

[0012] Preferably, the reflective component includes a protective reflective layer, which is fixedly connected to the upper end face of the upper cover film. The upper end of the protective reflective layer is coated with a silver coating, and a plurality of triangular prism microprisms are fixedly connected to the upper end of the silver coating.

[0013] By adopting the above technical solution: the reflective layer is connected to the upper covering film, the silver coating enhances the reflective performance, and several triangular prism microprisms at the top further improve the reflective effect. Overall, it can effectively interfere with thrips, play a repelling role, and improve the protective capability of the mulch film structure.

[0014] Preferably, the plurality of the triangular prism microprisms are arranged in a rectangular array.

[0015] By adopting the above technical solution, a number of triangular prism microprisms are distributed in a rectangular array, which, together with a protective reflective layer and a silver coating, can enhance the reflective effect, continuously interfere with thrips, and improve the pest repellency effect of the mulch film structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In this utility model, the symmetrical distribution of the edge reinforcing fabric and the equidistant rotating ground nails can enhance the stability of the mulch film and prevent its displacement. In the repellency release structure, the anti-aging film is connected to the buffer layer to provide a stable environment for the repellent capsules. The capsule-encapsulating groove of the upper covering film fits the repellent capsules and is distributed in a rectangular array, which protects the repellent capsules and arranges them in an orderly manner. The anti-aging film can prevent the repellent from decomposing too quickly. These combinations can ensure the slow and stable release of the repellent, avoid the problem of rapid loss of repellent substances in traditional mulch films, and continuously exert the effect of repelling thrips, providing long-term protection for cowpea planting and reducing thrips damage.

[0018] 2. In this utility model, the protective reflective layer is fixedly connected to the upper covering film to provide support for the reflective structure. The silver coating can significantly enhance the reflective effect, making it more durable and stable. Several triangular prism microprisms distributed in a rectangular array can reflect light from multiple angles. Through the reflection and scattering of light, the visual system of thrips is interfered with. The phototaxis of thrips is used to keep them away from cowpea plants, thereby achieving the avoidance of thrips, improving the control effect of thrips during cowpea cultivation, and ensuring the healthy growth of cowpeas.

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] A thrips-repelling mulch film for cowpea cultivation includes a base layer 1. Within the base layer 1, from bottom to top, a barrier layer 2, a reinforcing layer 3, and a buffer layer 4 are fixedly connected. Edge reinforcing fabric 5 is fixedly connected to the lower left and lower right ends of the base layer 1. Three rotating ground stakes 6 are movably connected to the upper ends of the two edge reinforcing fabrics 5. Baffles 7 are fixedly connected to the upper outer surfaces of the six rotating ground stakes 6, and all six baffles 7 are located above the edge reinforcing fabrics 5. A thrips-repelling release structure 8 is fixedly connected to the upper end of the buffer layer 4, and a reflective component 9 is fixedly connected to the upper end of the thrips-repelling release structure 8.

[0029] In this embodiment, the two edge reinforcing fabrics 5 are symmetrically distributed from left to right, and the three longitudinally distributed rotating ground nails 6 are equidistantly distributed. The repellency release structure 8 includes an anti-aging film 81, the lower end of which is fixedly connected to the upper end of the buffer layer 4. A plurality of repellency capsules 82 are embedded in the upper end of the anti-aging film 81. An upper cover film 83 is provided directly above the anti-aging film 81, and a plurality of capsule encapsulation grooves 84 are opened at the lower end of the upper cover film 83. The positions of the plurality of repellency capsules 82 and the plurality of capsule encapsulation grooves 84 correspond and their sizes match. The repellent capsules 82 and several capsule encapsulation slots 84 are arranged in a rectangular array. The upper end face of the anti-aging film 81 is fixedly connected to the lower end face of the upper cover film 83. Several repellent capsules 82 are located between the anti-aging film 81 and the upper cover film 83. The reflective component 9 includes a protective reflective layer 91, which is fixedly connected to the upper end face of the upper cover film 83. The upper end of the protective reflective layer 91 is coated with a silver coating 92. Several triangular prism microprisms 93 are fixedly connected to the upper end of the silver coating 92, and the several triangular prism microprisms 93 are arranged in a rectangular array.

[0030] The above scheme involves symmetrically distributed edge reinforcement fabric 5 and equidistantly distributed rotating ground nails 6, which reinforce the mulch film and ensure its stability in the field. In the repellency and release structure 8, the anti-aging film 81 is connected to the buffer layer 4, and the repellent capsule 82 embedded in it is located in the capsule encapsulation groove 84. The upper cover film 83 covers it. The anti-aging film 81 can prevent the repellent from decomposing too quickly, and the upper cover film 83 protects the repellent capsule 82, ensuring that the repellent is released slowly and continuously repelling thrips. In addition, the protective reflective layer 91 of the reflective component 9 is connected to the upper cover film 83, the silver coating 92 enhances the reflective effect, and the triangular prism microprisms 93 are distributed in a rectangular array to interfere with thrips by reflecting light and enhance the repellency effect.

[0031] It should be noted that this utility model is a thrips-repelling mulch film structure for cowpea cultivation. During use, firstly, the barrier layer 2, reinforcing layer 3, and buffer layer 4 in the base layer 1 are sequentially fixedly connected, providing basic physical support and a functional foundation. The barrier layer 2 helps prevent excessive loss of nutrients and water from the soil, the reinforcing layer 3 enhances the strength of the mulch film, and the buffer layer 4 provides cushioning protection. Symmetrically distributed edge reinforcing fabric 5, along with rotating ground nails 6 and their corresponding baffles 7, allows the mulch film to be firmly fixed to the ground by inserting and rotating the rotating ground nails 6, preventing it from being blown away or displaced by the wind, thus ensuring the stability of the mulch film. In the thrips-repelling release structure 8, an anti-aging film 81 is connected above the buffer layer 4, and its embedded thrips-repelling... The repellent capsule 82 is located within the capsule encapsulation groove 84 of the upper covering film 83. The anti-aging film 81 can delay the decomposition of the repellent. The upper covering film 83 protects the repellent capsule 82. The repellent substance in the repellent capsule 82 can be slowly released, which has a repellent effect on thrips. The protective reflective layer 91 of the reflective component 9 is located above the upper covering film 83. The silver coating 92 and the triangular prism microprisms 93 distributed in a rectangular array can effectively reflect light. By utilizing the phototaxis of thrips, their activity is interfered, making it difficult for thrips to approach the cowpea plant. Therefore, through the overall structural components, the drawbacks of traditional chemical control are avoided, and effective repellency of thrips is achieved. At the same time, the basic function of the mulch film is fulfilled, providing more environmentally friendly and longer-lasting protection for cowpea planting.
