[0075] To facilitate understanding of the technical solutions of this application, the technical solutions of this application will be further described below with specific embodiments.
[0076] Example 1
[0077] Taking the 'Floor of Bouquet Camellia' cut flowers as an example, this study examines the effect of 1-methylcyclopropene gas treatment on the preservation of bouquet camellia cut flowers.
[0078] 1.1 Implementation Method
[0079] Set up a 1-methylcyclopropene gas concentration of 450 nl / L, repeat 3 times. The stems of the 'Floral Waterfall' cut flowers are 40cm-50cm long. After being sealed and treated with 1-methylcyclopropene gas for 24 hours, they are then vaseed again with a preservative solution (which can be the preservative solution of this application, or Flower Life Preservative Solution, etc.) (vase arrangement experiment diagram is shown in the figure). Figure 2 As shown in the figure, record the opening rate, fresh weight, fresh weight change, moisture balance value, etc. daily. The specific calculation method is as follows:
[0080] (1) Opening rate: Number of flowers open on each branch on the same day / Total number of buds on each branch × 100%;
[0081] (2) Fresh weight: The weight of the flower branches was measured daily using a balance by weighing method;
[0082] (3) Fresh weight change: (fresh weight of the day - fresh weight of the previous day) / fresh weight of the previous day;
[0083] (4) Moisture balance value: Water absorption = Fresh weight of the day - Fresh weight of the previous day, Water loss = Total weight of the day - Total weight of the previous day, Moisture balance value is the difference between water absorption and water loss.
[0084] 1.2 Results and Analysis
[0085] The novel ethylene inhibitor 1-MCP is a monocyclic propylene compound that effectively inhibits the effects of ethylene and is environmentally friendly. It is often used as a substitute for silver thiosulfate. This study aimed to determine the preservation effect of 450 nl / L 1-MCP on 'Cascade Bouquet' cut flowers. The results are as follows:
[0086] (1) From the perspective of openness rate (e.g.) Figure 3 As shown in the figure, the opening rate of 'Floor Cascade' cut flowers treated with 450 nl / L was higher than that of the control group, approaching 40%, indicating that 1-MCP treatment can increase the opening rate of 'Floor Cascade' cut flowers.
[0087] (2) From the perspective of fresh weight change (e.g. Figure 4 As shown in the figure, the fresh weight of 'Floor Flower' cut flowers treated with 450 nl / L decreased more slowly than that of the control group, indicating that 1-MCP treatment can slow down the decrease in fresh weight of 'Floor Flower' cut flowers.
[0088] (3) From the perspective of water balance (e.g.) Figure 5 As shown in the figure, the overall moisture balance value of the 'Floor of Flowers' cut flowers treated with 450 nl / L was higher than that of the control group, indicating that 1-methylcyclopropene treatment can delay the water metabolism of 'Rose Jade' cut flowers and prolong their vase life.
[0089] In conclusion, compared with the control group, the 'Cascade of Flowers' cut flowers treated with 450 nl / L 1-MCP had a higher opening rate, a slower decline in fresh weight, and a higher moisture balance value. This indicates that 1-methylcyclopropene treatment can effectively improve the opening rate and moisture balance value of cut flowers and delay the decline in fresh weight.
[0090] Example 2
[0091] Taking 'Meiyu' cut flowers as an example, this study examines the effects of different components in the preservative solution on the preservation effect of 'Meiyu' cut flowers.
[0092] 2.1 Implementation Method
[0093] 'Meiyu' cut flowers have stems 40-50cm long and about 30 leaves. Vaseline experiments were conducted using solutions of 20g / L sucrose, 100mg / L salicylic acid, 25mg / L 6-BA, and 100mg / L aluminum sulfate (see vaseline experiment diagram). Figure 6 As shown in the figure, the vase life, opening rate, fresh weight, fresh weight change value, and moisture balance value were measured, and the results were repeated 3 times.
[0094] 2.2 Results and Analysis
[0095] 2.2.1 Effect of sucrose treatment on the preservation effect of 'Meiyu' cut flowers
[0096] From the perspective of openness rate (e.g.) Figure 7 As shown), the 20 g / L sucrose solution treatment showed higher results than the control group ( Figure 7 The control group (CK) consisted of 'Rose Jade' cut flowers placed in distilled water; changes in fresh weight (e.g.) Figure 8 (as shown) and water balance value (e.g.) Figure 9 As shown in the figure, there was little difference between the treatment group and the control group in the early stage, but in the later stage, the moisture balance value and fresh weight change value of the treatment group were higher than those of the control group. Figure 8 and Figure 9 Based on the CK in the sample, 20 g / L is considered to be the appropriate concentration of sucrose solution for treating 'Meiyu' cut flowers.
[0097] 2.2.2 Effect of salicylic acid treatment on the preservation effect of 'Meiyu' cut flowers
[0098] From the perspective of openness rate (e.g.) Figure 10 As shown in the figure, there was little difference between the pretreatment group and the control group, while the pretreatment group had a lower incidence of the disease than the control group in the later stage. Figures 10 to 12 (CK) in the data; from the change in fresh weight (e.g. Figure 11 (as shown) and water balance value (e.g.) Figure 12 As shown in the figure, the treatment group was slightly lower than the control group in the early stage and slightly higher than the control group in the later stage, but the difference was not significant. However, the vase life of the 100 mg / L salicylic acid solution was the longest, reaching 11 days. Therefore, it is believed that the 100 mg / L salicylic acid solution is the appropriate salicylic acid solution for 'Meiyu' cut flowers.
[0099] 2.2.3 Effect of 6-BA solution treatment on 'Rose Jade' cut flowers in vase
[0100] From the perspective of openness rate (e.g.) Figure 13 As shown), the 20 mg / L 6-BA (6-benzylaminopurine) solution was significantly higher than the control group (as shown). Figures 13 to 15 (CK) in the data; from the change in fresh weight (e.g. Figure 14 (as shown) and water balance values (e.g.) Figure 15 As shown in the figure, the treatment group was slightly lower than the control group in the early stage and slightly higher than the control group in the later stage. Therefore, it is believed that 20 mg / L is the appropriate concentration of 6-BA solution for treating 'Meiyu' cut flowers.
[0101] 2.2.4 Aluminum sulfate solution treatment for 'Rose Jade' cut flowers vase arrangement effect
[0102] From the perspective of openness rate (e.g.) Figure 16 As shown in the figure, the aluminum sulfate solution treatment group had higher levels than the control group ( Figures 16 to 18 (CK) in the data; from the change in fresh weight (e.g. Figure 17 (as shown) and water balance value (e.g.) Figure 18 As shown in the figure, the treatment group was slightly higher than the control group, therefore it is believed that 100 mg / L is the appropriate concentration of aluminum sulfate solution for treating 'Meiyu' cut flowers.
[0103] Example 3
[0104] Taking 'Floor of Flowers' cut flowers as an example, this study examines the impact of the preservative solution formula on the preservation effect of 'Floor of Flowers' cut flowers.
[0105] 3.1 Implementation Method
[0106] 'Cascade of Flowers' cut flowers have stems 40cm-50cm long. A vase test was conducted using preservative solution formula F (20g / L sucrose + 100mg / L salicylic acid + 25mg / L 6-BA + 100mg / L aluminum sulfate solution) (vase test diagram shown). Figure 19 As shown in the figure, the vase life, opening rate, fresh weight, fresh weight change value, and moisture balance value were measured, and the results were repeated 3 times.
[0107] 3.2 Results and Analysis
[0108] From the perspective of openness rate (e.g.) Figure 20 As shown), the treatment group had higher rates than the control group ( Figure 20 In the control group (CK), the 'Floor of Flowers' cut flowers placed in distilled water) achieved a 60% increase; the change in fresh weight (e.g.) Figure 21 (as shown) and water balance value (e.g.) Figure 22 As shown in the figure, the treatment group showed higher rates than the control group. Therefore, it is believed that the preservative formulation F can improve the opening rate of the 'flower waterfall', enhance the water metabolism of cut flowers, and delay the senescence of cut flowers. The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features of the above embodiments have been described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
