Description

Technical Field

[0001] The utility model relates to the technical field of fruit bagging, in particular to a special bagging for grapefruit planting. Background Art

[0002] Pomelo fruit bagging technology is one of the effective supporting technical measures for producing pollution-free pomelo fruit products. Bagging during the pomelo fruit expansion period can effectively prevent bird invasion, pest damage (fruit flies, red spiders, thrips, scale insects, snails, noctuids, etc.), and damage from wind, rain and sunlight, reduce the amount and frequency of pesticide use, and reduce pesticide residues in pomelo fruit products. Bagging can also produce a local greenhouse effect, so that the pomelo fruit maintains a relatively stable humidity and temperature, the peel is shiny and evenly colored, the fruit is sweet, and the growth period is shortened. Therefore, bagging technology is of great significance for the production of high-quality, pollution-free pomelo fruit.

[0003] However, the pomelo fruit bags currently used include single-layer paper bags, double-layer kraft paper bags or nylon mesh bags (e.g. Luo Zhiliang, Fang Jinchuan, He Huilan. A preliminary analysis of pomelo fruit bagging technology and benefits [J]. Fujian Tropical Crops Science and Technology, 2014, (1): 31-33). There are problems to varying degrees during use: single-layer paper bags are prone to rot after being soaked in rain for a long time; double-layer kraft paper bags have poor light transmittance and cannot ensure sufficient sunlight exposure, causing the pomelo peel to turn yellow and being unfavorable for observing the growth and development of the fruit; nylon mesh bags are not effective in preventing scale insects. The above-mentioned bags are all disposable and rarely reused, which not only causes resource waste and environmental pollution, but also requires the removal of old bags and secondary bagging before the pomelo can be packed and sold when it is picked and sold. This operation is time-consuming, labor-intensive, and costly, placing a heavy burden on fruit farmers. Utility Model Content

[0004] In view of the above problems, the utility model provides a special bag for grapefruit planting, which not only has good air permeability and light transmittance, as well as basic protective functions such as preventing bird invasion, pests and diseases, and damage from wind, rain and sunlight, but also has a packaging function for picking and selling.

[0005] The specific technical scheme of the utility model is: a special bag for grapefruit planting, comprising an outer bag and an inner bag, wherein the inner bag is placed in the outer bag, and the inner bag and the outer bag are independent structures separated from each other; the inner bag is closed in a circumferential direction, with an open end at the top and a closed end at the bottom, and a plurality of ventilation holes are provided on the inner bag; the outer bag is closed in a circumferential direction, with both the top and the bottom being open ends.

[0006] Furthermore, preferably, the material of the inner bag is polypropylene white non-woven fabric, and the material of the outer bag is a composite of an inner layer of pearl cotton and an outer layer of blue film.

[0007] Furthermore, preferably, the closed end of the inner bag is sealed by double-pass staggered heat sealing.

[0008] Furthermore, preferably, a tying strip is provided on the outer peripheral wall of the outer layer bag near the top, and a tying wire is penetrated through the channel formed between the tying strip and the outer peripheral wall of the outer layer bag for fixing the mouth of the bag to the fruit handle and tying the bag mouth.

[0009] The beneficial effects of the utility model are as follows: the utility model adopts a mutually separated double-layer bagging design, which can provide the basic protection and greenhouse effect of bagging technology for pomelo fruit, effectively prevent pomelo fruit from being attacked by birds, harmed by pests and diseases, and damaged by wind, rain and sunlight, greatly improve the appearance quality of the fruit, and create a greenhouse environment for the growth of pomelo fruit, which can maintain appropriate temperature and humidity, improve the sweetness of the fruit, improve the gloss of the fruit, shorten the fruit growth cycle, and increase the fruit yield, which is of practical significance for the production of high-quality, pollution-free pomelo fruit products. At the same time, the special bagging also breaks through the functional limitations of traditional bagging. When the fruit is ripe and the bag is removed, the outer bagging is removed and the inner bagging can be used as a packaging bag, eliminating the secondary packaging link for later sales, which not only saves time and effort, but also reduces the cost of fruit farmers, and has outstanding practical effects.

[0017] In order to make the technical problems and technical solutions solved by the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0019] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] like Figures 1 to 5 As shown, a special bag for grapefruit planting includes an outer bag 11 and an inner bag 21, the inner bag 21 is placed in the outer bag 11, and the inner bag 21 and the outer bag 11 are independent structures separated from each other; the inner bag 21 is closed circumferentially, the top is an open end, the bottom is a closed end, and a plurality of ventilation holes 22 are provided on the inner bag 21, providing good air permeability and light transmittance; the outer bag 11 is closed circumferentially, the top and the bottom are both open ends, and the bottom is an open design, which ensures that the inner bag 11 is air permeable and light transmittance.

[0021] Among them, the inner bag 21 is made of white polypropylene non-woven fabric material. The non-woven fabric has strong toughness, good light transmittance and air permeability, and can also play a basic protective role; the closed end of the inner bag 21 is sealed with double-pass ultrasonic staggered constant temperature heat sealing, which is more firm and has better load-bearing performance.

[0022] The outer bag 11 is made of a composite material of an inner layer of pearl cotton 12 and an outer layer of blue film 13, which can ensure light transmittance while preventing direct sunlight, and can also play a role of heat preservation and waterproofing.

[0023] The bag comprises, from inside to outside, an inner layer of polypropylene white non-woven fabric, an inner layer of pearl cotton 12 and an outer layer of blue film 13.

[0024] During production, the perimeter of the opening end of the inner bag 21 is 76 cm, the height of the inner bag 21 is 38 cm, and the size of the outer bag 11 is slightly larger than the inner bag 21, so as to ensure that the outer bag 11 is set outside the inner bag 21 to form a double-layer bag. This size can be conventionally adjusted according to the variety of pomelo fruit, so that the bag size is consistent with the expanded growth size of the pomelo fruit, avoiding waste of materials and increased costs caused by over-large bags, which is a common sense choice for those skilled in the art.

[0025] When bagging, the inner bag 21 and the outer bag 11 are sequentially put on the outside of the pomelo fruit, and the top ends of the inner bag 21 and the outer bag are fixed on the fruit handle with a tie wire and the bag mouth is tied tightly. When bagging, ensure that the fruit is in the center of the bag body, and the side wall of the inner bag 21 is covered by the outer bag 11. When removing the bag, the outer bag 11 is removed, and the inner bag 21 is retained as the outer packaging bag of the pomelo fruit, and is removed and packed together with the pomelo fruit.

[0026] like Figure 6 As shown, in order to facilitate the fixing and sealing of the bag, a tying strip 31 is provided on the outer peripheral wall of the outer layer bag 11 near the top, and a tying wire 32 is penetrated through the channel formed between the tying strip 31 and the outer peripheral wall of the outer layer bag 11. When bagging, the mouth of the bag can be fixed to the fruit handle and the bag mouth can be tied by pulling the tying wires 32 extending from both ends of the tying strip 31.

[0027] The special bag of the utility model is a double-layer bag separated from each other. When it is put on the outside of the pomelo fruit at the same time, the inner bag plays the role of light transmission, air permeability and pest prevention. The outer bag ensures light transmission while preventing direct sunlight, and can also play a role of heat preservation and waterproofing, providing the basic protection and greenhouse effect of bagging technology for the growth of pomelo fruit, effectively preventing pomelo fruit from being attacked by birds, harmed by pests and diseases, and damaged by wind, rain and sunlight, greatly improving the appearance quality of the fruit, and creating a greenhouse environment for the growth of pomelo fruit. It can maintain appropriate temperature and humidity, improve the sweetness of the fruit, improve the gloss of the fruit, shorten the fruit growth cycle, and increase the fruit yield, which is of practical significance for the production of high-quality, pollution-free pomelo fruit products. At the same time, the special bag also breaks through the functional limitations of traditional bagging. When the fruit is ripe and the bag is removed, the inner bag can be used as a packaging bag after the outer bag is removed, eliminating the secondary packaging link for later sales, which not only saves time and effort, but also reduces the cost of fruit farmers, and has outstanding practical effects.

[0028] Application:

[0029] In order to verify the effect of the bagging described in the utility model, the bagging is applied to green-skinned red-heart pomelo fruit, and the specific test varieties are: the new variety "Yunqing No. 1", Ruby Green Pomelo Dongshi Zao Pomelo, and Golden Honey Pomelo. During the pomelo fruit expansion period, the pomelo fruit is bagged, and the bagged fruit can effectively avoid wind and rain, avoid sunlight, prevent pests and diseases and bird damage, especially prevent fruit flies, red spiders, thrips, scale insects, etc., and correspondingly reduce the pollution of pesticides and dust, reduce other mechanical injuries from the outside world, and create a good micro-environment for the growth and development of fruits to seek benefits and avoid harm. The fruit peel is emerald green and smooth, with uniform color, few rust spots and pests, no depressions on the top of the fruit, no milk convexity, and no obvious radial grooves on the fruit base. The fruit is full of juice, tender flesh, sweet taste, low acidity, single fruit weight 1200-2000g, the central column is full, there is no internal cracking, the capsule petals are neat, the number of capsule petals is 12-16, and the pomelo fruit is high-quality and high-yield.
