Embodiment 1～3

[0029] Examples 1-3: With the support of Zhengzhou Science and Technology Research Project (20140764), the inventor conducted systematic research on the preservation of cut rose flowers. Among them, a series of aqueous solutions with different chitosan oligosaccharide contents were developed and screened as fresh cut rose flowers. agent, and its concentration is shown in Table 1.

[0030] deal with Chitooligosaccharide content (μg / ml) control 0 Example 1 1 Example 2 50 Example 3 100

[0031] Application test of the above-mentioned rose cut flower preservative

[0032] (1) Test material: rose for test ( Rosa hybrid Hort. ) variety is 'Sasa 90 # ’, purchased from Chenzhai Flower Market, Zhengzhou City, Henan Province. Choose robust flower branches that are ready to bloom and have basically the same size as the test material. Cut off the stem end of the Chinese rose obliquely in water, keep the flower branch about 30cm long, and keep 2...

Embodiment 4

[0051] Embodiment 4: a kind of fresh-keeping method of Chinese rose cut flower, comprises the steps:

[0052] (1) Cut the end of the rose stem obliquely in water, keep the flower branch 30cm long, and keep 2 compound leaves at the lower part of the flower;

[0053] (2) Insert the cut rose vase in distilled water, spray the cut rose fresh-keeping agent (10 μg / ml chitosan oligosaccharide solution) every day, and observe the fresh-keeping effect and water absorption of the sprayed rose cut flowers. The results are shown in Table 5. 6,7.

Embodiment 5

[0054] Embodiment 5: a kind of fresh-keeping method of Chinese rose cut flower, comprises the steps:

[0055] (1) Cut off the end of the rose stem purchased from the flower market obliquely in water, keep the flower branch 30cm long, and keep 2 compound leaves at the lower part of the flower;

[0056] (2) Then immerse all the cut rose flower heads in the cut rose flower preservative (containing 10 μg / ml chitosan oligosaccharide, 0.1% PVP). After the petals are all soaked, take them out to dry, and then insert the rose branches into distilled water After the middle period, observe the effect of the above-mentioned coating solution on the fresh-keeping effect and water absorption of cut rose flowers, and the results are shown in Tables 5, 6, and 7.

[0057] Observations from Examples 4 and 5 show that the chitosan oligosaccharide preservation solution can also prolong the vase life of cut flowers by 1.9d and 2.3d by spraying and coating (Table 5), especially the cut flowers that...

Abstract

The invention relates to a Chinese rose cut-flower antistaling agent and an antistaling application of the Chinese rose cut-flower. The technical problem that the antistaling effect of Chinese rose cut-flowers is not ideal is solved. The antistaling agent comprises 0.5-40ug / ml of chitosan oligosaccharide. The application method comprises the steps of: directly inserting branches of cut-flowers into the antistaling effect, or inserting the branches of cut-flowers into the water and spraying the antistaling agent to the branches of the cut-flowers every day, or wetting flower heads of the cut-flowers by using the antistaling agent and inserting the branches of cut-flowers into the water. The antistaling agent has a simple formula; the net weight value of the Chinese rose cut-flower can be effectively increased, the stress resistance of the Chinese rose cut-flower is increased, the balance of water contents of the Chinese rose cut-flower can be effectively regulated, and the condition of the water contents in the Chinese rose cut-flower body can be improved, so that the aging progress of the Chinese rose cut-flower is delayed, the vase life is prolonged, and the pollution to the environment caused by using ethylene antagonists such as silver nitrate, silver thiosulfate can be effectively avoided. The antistaling treatment method is simple, the Chinese rose cut-flower antistaling agent is convenient to use, the antistaling effect is obvious, the flowering speed of the Chinese rose is prolonged, the color of the Chinese rose cut-flower is effectively retained, and the antistaling time is long.

Description

technical field [0001] The invention relates to a fresh-keeping agent, in particular to a fresh-keeping agent for cut rose flowers and its fresh-keeping application. Background technique [0002] At present, after years of development, the fresh-cut flower industry has become one of the pillar industries of agriculture in many countries and a new economic growth point of agriculture. After the cut flowers are separated from the parent body, their nutrient source is cut off, and the original balance conditions are destroyed. In addition, the adverse effects of the environment and microorganisms and a series of physiological and biochemical reactions inside the cut flowers lead to the senescence of the cut flowers, resulting in a shortened viewing period. For China, the distribution of cut flower production areas is relatively concentrated, and the regionalization of cut flower production is prominent. Therefore, the storage and preservation of cut flowers after harvest and du...
