Embodiment 1

[0019] The fresh-keeping method for fresh flowers of the present embodiment comprises the following steps:

[0020] (1) Fix the flowers on the tray with holes;

[0021] (2) Add a polyvinyl alcohol solution with a mass fraction of 3% and a pH of 2.0 into the reservoir of the high-viscosity liquid spray gun, and turn on the air compressor;

[0022] (3) When the air compressor stops running, open the air control valve and hold the trigger until the compressed air valve is opened; continue to hold the trigger, the gun needle is pulled back by the trigger, the polyvinyl alcohol solution flows out from the nozzle, and is simultaneously Atomization of compressed air from the hood;

[0023] (4) Point the nozzle at the flowers fixed on the tray and spray evenly;

[0024] (5) Dry the sprayed flowers in a drying oven at 30° C. for 3 hours to obtain flowers covered with a polyvinyl alcohol film.

Embodiment 2

[0026] The fresh-keeping method for fresh flowers of the present embodiment comprises the following steps:

[0027] (1) Fix the flowers on the tray with holes;

[0028] (2) Add the polyvinyl alcohol solution with a mass fraction of 4% and pH 7.0 into the reservoir of the high-viscosity liquid spray gun, and turn on the air compressor;

[0029] (3) When the air compressor stops running, open the air control valve and hold the trigger until the compressed air valve is opened; continue to hold the trigger, the gun needle is pulled back by the trigger, the polyvinyl alcohol solution flows out from the nozzle, and is simultaneously Atomization of compressed air from the hood;

[0030] (4) Point the nozzle at the flowers fixed on the tray and spray evenly;

[0031] (5) Dry the sprayed flowers in a drying oven at 23° C. for 6 hours to obtain flowers covered with a polyvinyl alcohol film.

Embodiment 3

[0033] The fresh-keeping method for fresh flowers of the present embodiment comprises the following steps:

[0034] (1) Fix the flowers on the tray with holes;

[0035] (2) Add the polyvinyl alcohol solution with a mass fraction of 5% and pH 4.5 into the reservoir of the high-viscosity liquid spray gun, and turn on the air compressor;

[0036] (3) When the air compressor stops running, open the air control valve and hold the trigger until the compressed air valve is opened; continue to hold the trigger, the gun needle is pulled back by the trigger, the polyvinyl alcohol solution flows out from the nozzle, and is simultaneously Atomization of compressed air from the hood;

[0037] (4) Point the nozzle at the flowers fixed on the tray and spray evenly;

[0038] (5) Dry the sprayed flowers in a drying oven at 15° C. for 10 hours to obtain flowers covered with a polyvinyl alcohol film.

Abstract

The invention discloses a flower freshness-maintaining method. The flower freshness-maintaining method includes: (1) spraying polyvinyl alcohol solution with mass percentage ranging from 3% to 5% and the pH ranging from 2.0 to 7.0 to each part of flowers evenly; and (2) obtaining a refreshed flower by drying the flowers processed in step (1). A layer of polyvinyl alcohol film is coated on the surfaces of the flowers, on the conditions of maintaining original colors and shapes of the flowers, evaporation of flower inner moisture is reduced, and preservation time of the flowers is prolonged; and meanwhile, mechanical property of the flowers is improved, and flower transportation is facilitated.

Description

technical field [0001] The invention relates to a fresh-keeping method for fresh flowers, which belongs to the technical field of fresh-keeping plants. Background technique [0002] my country is one of the countries with the richest plant resources in the world due to its vast territory and great regional differences. There are about 30,000 kinds of plants in my country, among which flower plants account for most of them, such as rose, viburnum, dragon girl, Daphne, Phnom Penh Daphne, sweet-scented osmanthus, pigeon flower, nocturnal hemp, Mudan, plum blossom, wintersweet Wait. Flower plants have good ornamental value, so they are deeply loved by people. However, due to the great regional differences in flower plants, flowers are easy to evaporate and lose water, and are easily damaged. Therefore, the storage and transportation of flowers have become a bottleneck restricting the development of the flower industry. [0003] At present, there is no effective way to preserve...
