[0024] As described above, the present invention provides, in a first aspect, a bottle-insertion liquid for preserving cut branches of the scutellaria baicalensis, wherein the bottle-insertion liquid comprises a fungicide, an organic acid, a surfactant, an energy substance, and water;

[0025] in:

[0026] The bactericide is 8-hydroxyquinoline citrate and / or sodium benzoate;

[0027] The organic acid is citric acid and / or ascorbic acid;

[0028] The energy material is glucose or sucrose.

[0029] In some preferred embodiments, the bottle insertion solution comprises a bactericide, an organic acid, a surfactant, an energy substance and the balance water.

[0030] In other preferred embodiments, the surfactant is Triton X-100.

[0031] Although both citric acid and ascorbic acid are organic acids, they both have the effect of reducing the pH of the bottle-insertion liquid. However, citric acid also participates in the metabolism of the cut branches of the Chinese hollyhock tree, and ascorbic acid also has an antioxidant effect. The inventors have found that the combination of the two has a significantly better effect. Therefore, in other preferred embodiments, the bottle-insertion liquid contains citric acid and ascorbic acid.

[0032] Although both 8-hydroxyquinoline citrate and sodium benzoate are used as fungicides, the fungicidal effect may be insufficient if used alone at conventional concentrations; if used alone and the concentration of a single fungicide is increased, it will cause toxicity to the cut branches. The inventors have found that the combination of 8-hydroxyquinoline citrate and sodium benzoate can achieve sufficient fungicidal effects without causing toxicity to the cut branches. Therefore, in other preferred embodiments, the bottle insert solution contains 8-hydroxyquinoline citrate and sodium benzoate.

[0033] In other more preferred embodiments, the vial solution comprises citric acid and ascorbic acid, and comprises 8-hydroxyquinoline citrate and sodium benzoate.

[0034] In some more preferred embodiments, the vial solution comprises:

[0035] 100-200 mg / L (for example, 110, 120, 130, 140, 150, 160, 170, 180 or 190 mg / L) of 8-hydroxyquinoline citrate;

[0036] 100-200 mg / L (for example, 110, 120, 130, 140, 150, 160, 170, 180 or 190 mg / L) of sodium benzoate;

[0037] 100-500 mg / L (e.g., 200, 300 or 400 mg / L) of citric acid;

[0038] 10-50 mg / L (e.g., 20, 30 or 40 mg / L) of ascorbic acid;

[0039] 10-40 μl / L (e.g., 20, 25, 30 or 35 μl / L) of Triton X-100;

[0040] 5 to 20 g / L (e.g., 10 or 15 g / L) of glucose.

[0041] Regarding the concentration of each component, if the concentration of one or some components, such as Triton X-100, is too high, it may have an adverse effect on the newly grown leaves.

[0042] In some particularly preferred embodiments, the vial solution comprises:

[0043] 100 mg / L 8-hydroxyquinoline citrate;

[0044] 100mgl / L sodium benzoate;

[0045] 500 mg / L citric acid;

[0046] 25 mg / L ascorbic acid;

[0047] 20 μl / L Triton X-100;

[0048] 10g / L of glucose.

[0049] In some preferred embodiments, the energy substance is glucose, and the concentration of the glucose in the bottle liquid is less than 20g / L, for example, it can be more than 1g / L, more than 2g / L, more than 3g / L, more than 4g / L, more than 5g / L, more than 6g / L, more than 7g / L, more than 8g / L, more than 9g / L, more than 10g / L and less than 20g / L. Preferably, the concentration of glucose is greater than zero and not greater than 10g / L. The inventors have found through experiments that if the concentration is too high, it will significantly affect the absorption of water by the scutellaria oleifera cuttings. However, if an appropriate amount of glucose is included, on the one hand, it can provide energy substances for the scutellaria oleifera cuttings, and it can also control the scutellaria oleifera cuttings to grow red leaves together with other components, thereby improving the ornamental value of the scutellaria oleifera cuttings and satisfying the ornamental needs of consumers for more and more diverse flowers.

[0050] Therefore, the present invention provides a method for controlling the growth or quantity of red leaves of cut branches of the Chinese dwarf jasmine by regulating the concentration of glucose in the bottle liquid, thereby adjusting the leaf color of the cut branches of the Chinese dwarf jasmine, especially the red leaves, as required. Preferably, the glucose is used in the form of the bottle liquid described in the first aspect of the present invention.

[0051] In a second aspect, the present invention provides the use of the vase liquid described in the first aspect of the present invention in the vase preservation of cut branches of the dwarf ...

[0052] (1) Prevent or reduce leaf drop problems;

[0053] (2) Promote water absorption;

[0054] (3) Extend the vase life;

[0055] (4) Regulate leaf color, especially control the growth of red leaves and adjust the number of red leaves.

[0056] The third aspect of the present invention also provides a method for preserving cut branches of Sophora japonica by inserting them into a vase, characterized in that the method comprises:

[0057] (1) Cut the terminal stem of the scutellaria baicalensis branch in water, preferably cutting off 3 to 5 cm of the terminal stem;

[0058] (2) Without splitting the end of the stem of the cut branch of the scutellaria baicalensis, insert it into the bottle of infusion solution;

[0059] Wherein, the bottle insertion liquid is the bottle insertion liquid described in the first aspect of the present invention.

[0060] Before vase placement, the stem ends of the cut branches of the dwarf ...

[0061] In some preferred embodiments, the cut branches of the Dictamni oleifera are inserted into the vase-insertion solution, and then maintained at an ambient temperature of 20-25° C. and an ambient relative humidity of 60% to 70%.

[0062] The present invention will be described below in the form of embodiments, but the protection scope of the present invention is not limited to these embodiments.

[0063] Example

[0064] Prepare the oleander cuttings bottle insert solution according to the formula shown in Table 1, and its components and concentrations are shown in Table 1.

[0065] The preparation method of the bottle insert liquid of each embodiment is as follows: add each component into tap water, stir evenly until dissolved, and obtain the bottle insert liquid. In embodiments 1 to 4, 2 liters of bottle insert liquid is prepared each time.

[0066] The test flowers were fresh cut branches of the jasmine tree purchased from the flower market. The stems at the ends were cut obliquely in water to a length of 4 cm. The stems were then inserted into the prepared bottle inserts of the embodiments. The bottle inserts were replaced every 10 days.

[0067] Each treatment group was set up with 3 bottles, each bottle used 2 cuttings, the ambient temperature was controlled at 22℃±2℃, and the relative humidity was controlled at 60-70%. The ornamental quality of the cuttings was evaluated every day. The observation period was 40 days.

[0068] Determination of water absorption: weigh the weight of the bottle and the bottle every day, record it as W a . Water absorption (gg -1 d -1 )=(W a -W a+1 ) / W0. Where W a+1 W a W0 is the initial weight of the cuttings in each vase on the day of vase insertion.

[0069] Evaluation method for vase life: When the leaves fall off or wilt to the point of losing their ornamental value, the vase life of the cut branch is considered to have ended, that is, the number of days from the date of vase placement to the end of the cut branch vase placement.

[0070] The measured index value of each treatment group is the average measured value of the cuttings in that treatment group.

[0071] Table 1. Bottle insert liquids of Comparative Example 1 and Examples 1-4

[0072]

[0073] The specific preservation effects are shown in Tables 2 and 3 and Figures 1 to 4 shown.

[0074] Comparing the experimental results of Example 1, Example 2, Example 3 and Example 4, it can be concluded that the vase liquid formulas of Examples 2 and 3 have similar performance in promoting water absorption of the cut branches of the Chinese daffodil, and the water absorption is significantly increased compared with that of Example 1, indicating that increasing the amount of organic acid and lowering the pH value of the solution can promote the water absorption capacity of the cut branches of the Chinese daffodil. The water absorption of Example 4 is reduced relative to that of Example 3, which is presumably because the absorption of the solution is not utilized by increasing the glucose concentration.

[0075] After about 10 days of vase insertion, except for Comparative Example 1, the cuttings of the Spanish jellyfish in Examples 1-4 all had new leaves on the top. Some leaves turned brown, but this did not affect the overall ornamental effect of the cuttings. After 20 days of vase insertion, when the vase liquid was replaced, it was found that there were white floating objects (microbial colonies) around the cuttings of Comparative Example 1, indicating that microorganisms were growing. The cuttings of the Spanish jellyfish in Comparative Example 1 also had new leaves on the top, but the number was smaller. After 30 days of vase insertion, the Spanish jellyfish in Example 2 had the most new leaves on the top, followed by Example Group 3, and then Example 1. Red new leaves grew on the tops of the cuttings of the Spanish jellyfish in Examples 1 and 4. After 40 days of vase insertion, the number of leaves that fell off after turning brown in the cuttings of the Spanish jellyfish in Examples 1 to 4 increased compared to the previous period, but they still maintained a high ornamental value. The red leaves of Example 1 still maintained a very high ornamental value, while the red new leaves of Example 4 were slightly shrunken, which may be due to the high concentration of one or some components of the vase liquid (such as Triton X-100) (see Figure 3 and Figure 4 ).
