Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rainproof bags, in particular to a rainproof bag used in the production process of broccoli. Background Art
[0002] Rainproof bags are an important means of protection for broccoli production in spring: ensure that broccoli is produced in autumn, winter and spring in southern China (the area between 23.26° and 30° north latitude of the Tropic of Cancer) when it is rainy and humid but the temperature is suitable, and protect broccoli according to its plant growth characteristics. The bags widely used in plant production in the market are mainly used in the production process of fruits to prevent insect pests and fruit flies, bees and birds from biting. And because the fruits of fruit trees do not directly participate in photosynthesis, most fruit tree plant bags do not need to be light-transmitting. In order to prevent rain without affecting sunlight, consider using plastic film bags that are impermeable and do not affect sunlight. However, because of its impermeability, the broccoli balls cannot breathe normally in the bag. The transpiration of the plant will release a lot of water vapor. If the environment where the broccoli balls are located is too humid, they are prone to various mildew diseases. Therefore, it is impossible to simply use plastic film bags to prevent rain. The practicality is poor and needs to be improved. Utility Model Content
[0003] The purpose of the utility model is to solve the technical problems raised in the above background technology.
[0004] The utility model adopts the following technical scheme: a rainproof bag for broccoli production, comprising a light-transmitting film, a one-way transparent film is fixedly installed on the lower surface of the light-transmitting film, a tying ring is fixedly installed on the bottom end of the one-way transparent film, and an iron wire is arranged inside the tying ring.
[0005] Preferably, the one-way permeable membrane is made of polyurethane. Here, polyurethane has good wear resistance and durability, and can maintain good performance after multiple uses. The one-way water permeability of the polyurethane material allows water vapor to be discharged but prevents external moisture from entering, maintaining a dry environment in the bag. The flexibility of polyurethane enables it to tightly wrap the broccoli and is not easily damaged.
[0006] Preferably, the light-transmitting film is made of polypropylene. Here, the polypropylene material has good light transmission performance, which helps plants to photosynthesize and promote growth. Polypropylene has good waterproof performance, which prevents rainwater from entering the bag. Polypropylene is a low-cost material suitable for large-scale production.
[0007] Preferably, the surface of the iron wire is provided with a galvanized layer. Here, the galvanized layer can effectively prevent the iron wire from rusting and improve its service life. The iron wire increases the firmness of the ring, ensuring that the bag tightly wraps the broccoli and is not easy to loosen. The galvanized treatment enables the iron wire to maintain good performance in various weather conditions and is not easily damaged.
[0008] Compared with the prior art, the advantages and positive effects of the utility model are:
[0009] In the utility model, by arranging a one-way permeable film, a tying ring and an iron wire, the bag can effectively prevent rain from directly contacting the broccoli head, thereby avoiding rotting of the head due to excessive rain. The bag adopts a material with strong light transmittance, thereby ensuring that the broccoli can fully receive sunlight during the photosynthesis process, which is beneficial to its growth and development. The bag adopts a one-way water-permeable material, allowing water vapor generated by transpiration to be released outward, keeping the bag dry, and preventing mildew caused by high humidity, thereby improving the health level and yield of broccoli, reducing the incidence of diseases, and increasing yield and quality, thereby bringing higher economic benefits. The utility model is particularly suitable for the rainy and humid autumn, winter and spring in southern China, and helps to carry out effective production in these seasons.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0016] Example
[0017] See also Figure 1-2The utility model provides a technical solution: a rainproof bag for broccoli production, comprising a light-transmitting film 1, a one-way transparent film 2 is fixedly installed on the lower surface of the light-transmitting film 1, a tying ring 3 is fixedly installed on the bottom end of the one-way transparent film 2, and an iron wire 4 is arranged inside the tying ring 3. The light-transmitting film 1 can effectively block rainwater and prevent rainwater from directly contacting the broccoli head. The light-transmitting film 1 ensures sufficient sunlight transmission, which is beneficial to the photosynthesis of broccoli. The one-way transparent film 2 can release the water vapor generated by transpiration to the outside, keep the inside dry, and prevent mildew caused by high humidity. The tying ring 3 and the iron wire 4 ensure that the bag is stable in wind and rain and will not be easily blown off or displaced by the wind. The material of the one-way transparent film 2 is polyurethane. Polyurethane has good wear resistance and durability, and can maintain good performance after repeated use. The one-way water permeability of the polyurethane material allows water vapor to be discharged but prevents external moisture from entering, thereby maintaining a dry environment in the bag. The flexibility of polyurethane enables it to tightly wrap the broccoli and is not easily damaged. The material of the light-transmitting film 1 is polypropylene. Polypropylene material has good light transmittance, which helps plants to photosynthesize and promotes growth. Polypropylene has good waterproof performance to prevent rainwater from entering the bag. Polypropylene is a low-cost material suitable for large-scale production. The surface of the iron wire 4 is provided with a galvanized layer, which can effectively prevent the iron wire 4 from rusting and improve its service life. The iron wire 4 increases the firmness of the tie ring 3 to ensure that the bag tightly wraps the broccoli and is not easy to loosen. The galvanized treatment enables the iron wire 4 to maintain good performance under various weather conditions and is not easily damaged.
[0018] Working principle: First, prepare the transparent film 1, the one-way transparent film 2, the tie ring 3 and the iron wire 4; then cut the transparent film 1 and the one-way transparent film 2 to the size according to the design requirements, fix the bottom end of the one-way transparent film 2 on the lower surface of the transparent film 1, and install the tie ring 3 at the bottom end of the one-way transparent film 2, ensuring that the tie ring 3 tightly wraps the edge of the one-way transparent film 2; then put the iron wire 4 into the tie ring 3, ensuring that the opening of the tie ring 3 can be freely adjusted and fixed. During installation, carefully put the bag on the broccoli flower head, adjust the tie ring 3 and tighten the iron wire 4 so that the tie ring 3 is tightly fixed on the broccoli stem, ensuring that there is no looseness, and confirm that the environment inside the bag is dry. Finally, regularly check the fixing condition and internal dryness of the bag, especially after rain and high humidity weather, to ensure that the one-way water permeability of the one-way transparent film 2 works normally. If it is damaged or loose, replace or re-fix it in time. Through these steps, the rainproof bags can effectively protect the broccoli florets from rain while maintaining a suitable growing environment to ensure the quality and yield of the broccoli.
