Embodiment 1

[0017] The invention provides a recipe for the preparation of carnation cut flower fresh-keeping reagent of onion extract, and the test method is as follows:

[0018] Step 1: Pretreatment of onions, air-dry the onions in a cool place, and then put them into a drying oven for drying at a temperature of 35-40°C for 12 hours. Use a pulverizer to crush the dried onions, pass through a 20-mesh sieve, bag them separately, and store them at 4°C for later use;

[0019] Step 2: Preparation of the onion water extract, weigh 40g of the crushed onion sample, divide it into 2 parts for later use (20g each), put each part into a measuring cup, add 1000ml of water, and soak in a warm water bath at 50°C for 12 hours Boil for another 30 minutes, filter to remove slag, and constant volume in a 1000ml volumetric flask to obtain the stock solution of plant extract, cool at 4°C and store for later use, with a concentration of 0.02g / L;

[0020] Step 3: Carnation pretreatment, take carnation cut fl...

Embodiment 2

[0024] The present invention provides a preparation method of carnation cut flower fresh-keeping reagent of onion extract, and the configuration method is as follows:

[0025] Step 1: Pretreatment of onions, air-dry the onions in a cool place, and then put them into a drying oven for drying at a temperature of 35-40°C for 12 hours. Use a pulverizer to crush the dried onions, pass through a 20-mesh sieve, bag them separately, and store them at 4°C for later use;

[0026] Step 2: Preparation of onion ethanol extract, weigh 50g of crushed onion sample, add quantitative 95% ethanol, the standard is to immerse the sample by more than 4cm according to the sample volume, soak, put it in a shaker and shake for 48h. Filtrate to obtain the filtrate and residue. The second time: add an appropriate amount of 95% ethanol to the residue that was lifted for the first time, just immerse the sample by 1 cm, soak it, and shake it in a shaker for 24 hours. Filtrate to obtain the filtrate and re...

Abstract

The invention discloses a preparation process of a cut carnation flower preservation reagent for an onion extracting solution. The preparation process comprises the following steps: preparing an onionaqueous extract, weighing 40g of crushed onion sample, dividing into 2 parts for later use (namely 20g per part), adding each part of the onion sample into a measuring glass, adding 1000ml of water,soaking in a warm water bath at 50 DEG C for 12 hours, boiling for 30 minutes, filtering to remove residues, fixing the volume by a 1000ml of volumetric flask so as to obtain a plant extract stock solution, cooling to 4 DEG C and preserving for later use at a concentration of 0.02 g / L, and adding the onion aqueous extract into a bottle, wherein the volume of the total vase solution is 300ml; and adding the originally extracted onion aqueous extract into water, mixing to be 60%, wherein the concentration of the onion aqueous extract of the cut carnation flower preservation reagent is 60%. The vase preservation solution of carnation is strong in preservation effect and extremely low in environmental pollution, does not contain any substance harmful to the human body and has the effects of being green and environmentally friendly. The pH value of the preservation reagent is always maintained in a weakly acidic range from 3.5 to 4.5, so that growth of microbes is inhibited, and blockage tovascular bundle tissues of stems is reduced.

Description

technical field [0001] The invention relates to a fresh-keeping reagent for cut flowers, in particular to a preparation process of the fresh-keeping reagent for carnation cut flowers with onion extract. Background technique [0002] Caryophyllus (Dianthus Caryophyllus.), a well-known carnation, Caryophyllaceae, Caryophyllus, is a perennial herb with gorgeous and elegant flowers, rich and delicate colors, and a variety of varieties, including red, rose red, deep red, pink, yellow, orange and white , complex color, etc., with fragrance. Carnation is listed as one of the four major fresh cut flowers in the world. It has high ornamental value and economic value. At present, it is widely cultivated at home and abroad. Carnation represents good wishes such as maternal love, kindness, warmth, blessing, health and longevity, and true feelings. , and the flower arrangement viewing period is longer, so it is favored by consumers. It is widely used: baskets, bouquets, bouquets, corsa...
