Problems solved by technology

[0011] The present invention is aimed at the production problems of fruit blooming and fruit setting in the field at different times, uneven fruit ripening period, and the fruit ripening situation in the bag cannot be observed after the light-proof fruit bag is put on. Utilizing the characteristics that the fruit development time of the same variety is relatively stable, through The bottom of the fruit bag is affixed with different fading time indicator stickers to facilitate timely harvesting of fruit when it is ripe

Embodiment 1

[0030] Carambola blooms many times a year. It is a kind of fruit tree that continues to bloom and bear fruit. During the production process of carambola, fruit flies are seriously harmful, and it is basically impossible to realize commercial production without bagging. This example takes the Thai carambola as an example. It takes about 70-75 days for the Thai carambola to bloom to fruit maturity. In production, it is usually bagged 20 days after flowering and when the fruit is about 2.5 cm long. Harvestable.

[0031]A fruit bagging label indicating harvest time, comprising a fruit bagging label layer and a vacuum aluminum foil protection bag, the fruit bagging label layer is sequentially provided with a self-adhesive layer, a color-developing layer and a Waterproof layer.

[0032] In this embodiment, the self-adhesive layer is sequentially provided with a silicon-coated protective paper, an adhesive layer, a primer layer, and a white surface material from bottom to top.

Embodiment 2

[0038] 1 Sanhong honey pomelo is an important variety of Guanxi honey pomelo, mainly from mid-March to late April, with a long flowering period, continuous flowering and fruiting. Pomelo bagging can prevent diseases, insects, and sunburn, promote uniform color change of the peel, promote early maturity, and reduce the number of spraying. The outer skin of the bagged Sanhong honey pomelo is light pink, the sponge layer under the peel is pink, and the flesh is rose red, hence the name "Sanhong". Bagging is an important guarantee for the color of Sanhong pomelo, and it needs to be covered with a black inner layer of three-layer kraft paper bag, and it must be bagged for more than 90 days.

[0039] It takes about 180 days for Sanhong honey pomelo to bloom and ripen. In production, the young fruit is usually bagged when the fruit grows to a single fruit weight of 150 grams and the fruit’s transverse diameter is about 5 centimeters, and it takes more than 90 days to realize the peel...

Abstract

The invention discloses a fruit bagging label capable of prompting harvesting time. The fruit bagging label comprises a fruit bagging label layer and a vacuum aluminum foil protecting bag, wherein thefruit bagging label layer is provided with a non-setting adhesive layer, a color development layer and a waterproof layer sequentially from bottom to top; the non-setting adhesive layer comprises silicon-coated protective paper, an adhesive layer, a priming and a white surface material; the color development layer is prepared from liquid anthocyanin extracted from natural plant materials and additives, and the additives comprise ascorbic acid, hydrogen peroxide, metal ions and alkaline matters; and the anthocyanin in the color development layer is degraded to fade 5 to 200 days later, and white of the white surface material of the non-setting adhesive layer is shown, so that the aim of indicating fruit harvesting is achieved. According to the fruit bagging label, by using the characteristic that the same fruit tree variety is basically stable in fruit development time, through sticking indicating labels of different fading time to bottoms of fruit bags, the problem that harvesting isdifficult due to the fact that fruits on fruit trees are different in ripening time and cannot be identified after bagging is solved, mechanical damage to surfaces of the fruits is reduced, and the harvesting identification of ripe fruits is facilitated.

Description

technical field [0001] The invention belongs to the technical field of fruit harvesting of fruit trees, and in particular relates to a fruit bagging label for prompting harvest time. Background technique [0002] Carambola, pomelo, pear, loquat and other fruit trees in the field need to use kraft paper bags or black opaque paper bags for fruit bagging in order to prevent the damage of fruit flies, reduce the sun burn on the fruit surface, or improve the appearance of the fruit surface. Through bagging, the color of the fruit surface is improved, the fruit surface is evenly colored, the peel is smooth, and the appearance of the fruit is improved. The phenomenon of fruit cracking after rain is significantly reduced, the product quality and commodity value are improved, and the sales revenue of the fruit is increased; the bagging protects the fruit, It can effectively prevent a variety of diseases and insect pests, especially fruit flies. After bagging, pesticides, smoke and mi...
