Technical Field
[0001] This utility model relates to the field of agricultural planting materials technology, and in particular to a biodegradable weed-proof and antibacterial mulch film for chili pepper planting. Background Technology
[0002] Mulch film, also known as ground cover film, is usually transparent or black PE film, but green or silver films are also available. It is used for agricultural ground covering. Mulch film not only increases soil temperature, retains water, soil, and fertilizer, thus improving fertilizer efficiency, but also has multiple functions such as weed control, pest and disease prevention, drought and flood resistance, salt suppression and seedling protection, improvement of near-surface light and heat conditions, and hygiene and cleanliness of products.
[0003] Traditional plastic mulch films are difficult to degrade and pollute the soil. They also have limited functions. In chili pepper cultivation, weeds and diseases (such as blight and bacterial wilt) are prevalent. Chemical herbicides and pesticides can easily leave residues. Furthermore, existing biodegradable mulch films mainly rely on physical weed control and lack antibacterial functions.
[0004] Therefore, we propose a biodegradable weed-controlling and antibacterial mulch for chili pepper cultivation. Utility Model Content
[0005] The present invention mainly addresses the technical problems existing in the prior art and provides a biodegradable weed-proof and antibacterial mulch for chili pepper cultivation.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a biodegradable weed-controlling and antibacterial mulch film for chili pepper cultivation, comprising a mulch film body, the mulch film body including a light-transmitting weed-controlling layer, an antibacterial slow-release layer disposed at the bottom of the light-transmitting weed-controlling layer, a soil contact degradation layer disposed at the bottom of the antibacterial slow-release layer, the light-transmitting weed-controlling layer including an ultraviolet-blocking film, and the bottom of the ultraviolet-blocking film being fixedly bonded to the top of the antibacterial slow-release layer, the antibacterial slow-release layer including a capsaicin extract slow-release carrier layer, and the bottom of the capsaicin extract slow-release carrier layer being fixedly bonded to the top of the soil contact degradation layer, the soil contact degradation layer including a corn starch base film, and the top of the corn starch base film being fixedly bonded to the bottom of the capsaicin extract slow-release carrier layer.

[0029] Example 1: Biodegradable weed-controlling and antibacterial mulch for chili pepper cultivation, such as... Figures 1-2 As shown, the mulch film includes a main body 10, which includes a light-transmitting weed-control layer 11. A slow-release antibacterial layer 12 is disposed at the bottom of the light-transmitting weed-control layer 11, and a soil contact degradation layer 13 is disposed at the bottom of the slow-release antibacterial layer 12. The light-transmitting weed-control layer 11 includes an ultraviolet-blocking film 16, the bottom of which is fixedly bonded to the top of the slow-release antibacterial layer 12. A microporous array layer 15 is disposed at the top of the ultraviolet-blocking film 16, and a hydrophobic coating 14 is coated on the top of the microporous array layer 15. By setting the mulch film main body 10, weed growth can be effectively prevented, while inhibiting pathogens in the soil, reducing environmental pollution, protecting the healthy growth of chili crops, improving soil fertility, and providing a better growing environment for chili plants.
[0030] Example 2: Based on Example 1, as follows Figure 3As shown, the antibacterial slow-release layer 12 includes a capsaicin extract slow-release carrier layer 19, with the bottom of the capsaicin extract slow-release carrier layer 19 fixedly bonded to the top of the soil contact degradation layer 13. A natural antibacterial complex layer 18 is fixedly bonded to the top of the capsaicin extract slow-release carrier layer 19, and an adhesive layer 17 is fixedly bonded to the top of the natural antibacterial complex layer 18. The top of the adhesive layer 17 is fixedly bonded to the bottom of the ultraviolet blocking film 16. By setting a light-transmitting weed-control layer 11, the ultraviolet blocking film 16 in the light-transmitting weed-control layer 11 can effectively block ultraviolet rays, reducing the damage of ultraviolet rays to chili crops. Simultaneously, the design of the microporous array layer 15 and the hydrophobic coating 14 ensures both air permeability and prevents water penetration, keeping the inside of the mulch film dry. Through the setting of the antibacterial slow-release layer 12, the capsaicin extract slow-release carrier layer 19 in the antibacterial slow-release layer 12 can continuously release capsaicin, inhibiting pathogens in the soil and providing a healthy growth environment for chili crops. The addition of the natural antibacterial complex layer 18 further enhances the antibacterial effect.
[0031] Example 3: Based on Examples 1 and 2, as follows... Figure 4 As shown, the soil contact degradation layer 13 includes a corn starch base film 20, with the top of the corn starch base film 20 fixedly bonded to the bottom of the capsaicin extract slow-release carrier layer 19. An accelerated degradation layer 21 is fixedly bonded to the bottom of the corn starch base film 20, and a soil activation layer 22 is fixedly bonded to the bottom of the accelerated degradation layer 21. By setting up the soil contact degradation layer 13, which uses the corn starch base film 20 as the substrate, it has good biodegradability and can degrade naturally in the soil, reducing environmental pollution. The design of the accelerated degradation layer 21 can accelerate the degradation process of the mulch film and shorten the residual time of the mulch film in the soil. The soil activation layer 22 can improve the soil structure, increase soil fertility, and provide better growth conditions for chili crops.
[0032] The working principle of this utility model:
[0033] In use, this biodegradable weed-control and antibacterial mulch for chili cultivation is laid on the soil surface of the chili planting area. The UV-blocking membrane 16 in the light-transmitting weed-control layer 11 effectively blocks UV penetration, preventing damage to soil microorganisms and plant roots. Simultaneously, the microporous array layer 15 and hydrophobic coating 14 allow rainwater to easily penetrate the soil, keeping the mulch surface dry and reducing weed growth. The capsaicin extract slow-release carrier layer 19 in the antibacterial slow-release layer 12 continuously releases capsaicin and other natural antibacterial substances, effectively inhibiting the growth of pathogens in the soil and protecting chili plants from disease. The natural antibacterial complex layer 18 further enhances the antibacterial effect, while the adhesive layer 17 ensures a stable connection between the layers. The corn starch-based membrane 20 in the soil contact degradation layer 13, as a biodegradable material, gradually decomposes during contact with the soil, reducing environmental pollution. The accelerated degradation layer 21 accelerates the degradation process of the mulch, while the soil activation layer 22 improves soil structure and fertility, providing a better growing environment for the chili plants.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
