Fruit bagging label capable of prompting harvesting time

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...

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
