Problems solved by technology

[0004] In order to increase the shelf life of ripe but unmarketable grapes, prevent grapes from rotting, and cause economic losses, people have invented many storage methods for grapes for thousands of years, the most notable of which include cold storage storage, cellar storage, film storage, and earthen jars. Four types of storage; however, the texture of grapes is relatively "weak" and they are still perishable during storage

Embodiment 1

[0033] This embodiment provides a storage method for grapes, the purpose is to keep fresh unsold grapes with stalks, and improve the shelf life of post-harvest grapes; the specific process is as follows:

[0034] a. Grape pretreatment: After 5 p.m. on a sunny day, cut off the whole bunch of fully mature grapes together with the stems, remove cracked, rotten, damaged, and insect-infested fruits, and tie three strings on the grape stems. The end of the fruit stem is 2cm, and the connecting line between the binding points of the three thin ropes is controlled to be an equilateral triangle, and the other ends of the three thin ropes are glued together to form a triangular prism-shaped netting, so that the bound grapes can be hung in the hanging process. Hang vertically; hang the grapes tied with thin ropes on the hooks of the hanging rack, hang them on the hanging rack, spread them in a cool and ventilated place at 20°C for 3 hours, wipe off the surface fruit powder, and then hang ...

Embodiment 2

[0043] This embodiment provides a storage method for grapes, the purpose is to keep fresh unsold grapes with stalks, and improve the shelf life of post-harvest grapes; the specific process is as follows:

[0044]a. Grape pretreatment: After 5 p.m. on a sunny day, cut off the whole bunch of fully mature grapes together with the stems, remove cracked, rotten, damaged, and insect-infested fruits, and tie three strings on the grape stems. The end of the fruit stem is 2cm, and the connecting line between the binding points of the three thin ropes is controlled to be an equilateral triangle, and the other ends of the three thin ropes are glued together to form a triangular prism-shaped netting, so that the bound grapes can be hung in the hanging process. Hang vertically; hang the grapes tied with thin ropes on the hooks of the hanging rack, hang them on the hanging rack, spread them in a cool and ventilated place at 23°C for 5 hours, wipe off the surface fruit powder, and then hang t...

Embodiment 3

[0052] This embodiment provides a storage method for grapes, the purpose is to keep fresh unsold grapes with stalks, and improve the shelf life of post-harvest grapes; the specific process is as follows:

[0053] a. Grape pretreatment: After 5 p.m. on a sunny day, cut off the whole bunch of fully mature grapes together with the stems, remove cracked, rotten, damaged, and insect-infested fruits, and tie three strings on the grape stems. The end of the fruit stem is 2.5cm, and the connecting line between the binding points of the three thin ropes is controlled to form an equilateral triangle, and the other ends of the three thin ropes are glued together to form a triangular prism-shaped netting, so that the tied grapes are in the hanging process. Can hang vertically; hang the grapes tied with strings on the hooks of the hanging rack, hang them on the hanging rack, and spread them in a cool and ventilated place at 21°C for 4 hours, wipe off the surface fruit powder, and then dry t...

Abstract

The invention relates to the technical field of grape planting, and in particular to a grape storage method. According to the grape storage method provided by the invention, grapes are picked along with stems at dusk of sunny days; unqualified fruits are removed; the grapes are hung on a suspension frame; then spreading for cooling, pre-cooling, and winnowing treatment are carried out; an infusiontube and a plastic bubble sleeve each grape stem; the plastic bubbles are filled with a nutrient solution; grape trellis hung with the grapes are conveyed into a cellar; and "infusion treatment" is carried out on the grapes, so that continuous nutrient supply can be provided for the grapes during storage, death or nutrition dispersing of the grapes can be prevented, the shelf life of the picked grapes is effectively prolonged, and the grapes are kept fresh to the next spring. Compared with common cellaring of grapes, the storage method provided by the invention has the advantages that nutrients and moisture of the grapes stored by the grape storage method provided by the invention are basically equivalent to nutrients and moisture of fresh grapes.

Description

technical field [0001] The invention relates to the technical field of grape planting, in particular to a storage method for grapes. Background technique [0002] Grape, a kind of berry, is one of the oldest and most widely distributed fruits in the world. Humans began to cultivate this kind of fruit tree a long time ago. The berries are mostly round or oval, and the color varies with the variety. It accounts for almost a quarter of the world's fruit production; it has high nutritional value and is used in grape juice, raisins and wine. Large grains, thick skin, less juice, more water, easy separation of skin and flesh, sweet and sour taste, storage and transportation of Eurasian grapes, also known as grapes, generally grow in clusters, with yellow-green, red, black-blue or Purple. There is a thin skin on the outside of the pulp, and a thin frost on the outside of the skin. Some varieties are seedless. Grapes can be used as raw fruit, wine or raisins. In addition, it can...
