Description
Technical Field
The invention relates to the technical field of cut flower preservation, in particular to a Chinese rose cut flower vase solution and a using method thereof.
Background
China rose (rose) is a name of 'queen in flower' and is one of the most important fresh cut flowers with the largest sales volume. The most important quality of the fresh cut flowers is the vase life, and the vase life of most of Chinese rose varieties is 4-7 days. The vase life of a fresh cut flower is affected by various factors before and after harvest.
The fresh cut flowers are still a living organism after being harvested, carry out physiological metabolic processes such as respiration and transpiration, and provide energy required by life activities by consuming organic matters of the fresh cut flowers. The cutting of the parent to supply water and various nutrients gradually results in physiological and biochemical changes of the cut flower. If the required nutrients cannot be supplemented in time, the physiological and biochemical processes and influencing factors (temperature, relative humidity, gas components, microorganisms, mechanical and physical damage and the like) related to aging cannot be controlled in time, the cut flowers can be aged too early, cut flower buds cannot be opened sufficiently or even cannot be opened (catarrhal flowers and catarrhal buds), the bottle cut life is shortened, and the quality of the cut flowers after picking is influenced.
Respiration is the most important metabolic process after the cut flowers leave the mother body, and organic matters such as sugar, fat and protein in cells are oxidized under the action of enzyme to release energy. The respiration of the cut flower, in addition to providing energy, also enhances the disease resistance of the cut flower. With the prolonging of the breathing time and the increasing of the breathing intensity, the breathing substrate is gradually reduced, so that the normal physiological activities of the cut flowers can not be normally carried out, and the cut flowers are gradually decayed. Therefore, the respiration intensity is controlled, the metabolic speed of the cut flowers and the discharge of respiratory heat are slowed down, and the cut flowers are beneficial to prolonging the refreshing time. On the premise of not causing physiological disorder of the cut flowers, the cut flowers are treated and transported in a low-temperature environment as far as possible after being picked, so that the respiratory intensity of the cut flowers after being picked is reduced, or respiratory substrates are supplemented, and the important principle of maintaining normal metabolism and delaying senescence is realized.
The water has various functions on the cut flower, and not only can directly participate in various biochemical metabolic processes, but also can regulate the temperature of the cut flower, and maintain the swelling pressure of cells and the fresh state of the cut flower. After the cut flowers are harvested, water lost by transpiration cannot be supplemented, so that the transpiration amount is larger than the water absorption amount, the cut flowers are easy to lose weight and wither, the cell swelling pressure of the cut flowers is reduced, cell walls are bent and even broken, the cell membrane permeability is increased, the disease resistance of the cut flowers is reduced, and the corruption rate is increased.
Cut flowers mainly absorb water through the cut to realize water supply, and a water delivery pipe of the cut is gradually blocked due to the entering of bubbles, secretion such as emulsion and the like, the propagation of microorganisms and the like, so that the transpiration and water loss cannot be balanced with the water absorption, the withering, the bending, the difficult opening and the color change of petals of the cut flower leaves are caused, and the vase life and the ornamental value of the fresh cut flowers are seriously influenced.
The cut vase solution is a nutrient solution designed aiming at the ornamental period of cut vase, is mainly used by retailers and consumers, and mainly comprises the following main components: bactericides, organic acids, inorganic salts, saccharides, growth regulators, ethylene inhibitors and the like. The bactericide can inhibit the proliferation of microbes in the vase solution, prevent the obstruction of the scape catheter and promote the water absorption of flowers. The organic acid can reduce the pH value of the vase solution, inhibit the growth of microorganisms and contribute to the water absorption of cut flowers. The inorganic salt can increase the osmotic potential of the solution, is beneficial to maintaining the turgor pressure of petal cells, maintains the water balance of cut flowers and prolongs the bottle inserting time. The saccharides can provide energy substances for the vital activities of the cut flowers, and especially provide substrates for the respiration of plants. The growth regulator such as salicylic acid can reduce the content of MDA in petals, reduce the accumulation of free proline, relieve the water stress during the vase period of the cut vase, and delay aging.
The prior art CN1254175C provides a cut flower vase solution, which is prepared by dissolving 8-hydroxyquinoline, citric acid, 6-benzylpurine, vitamin E, 2-aniline and triton in water. The cut flower vase solution is a broad-spectrum cut flower vase solution suitable for different types of cut flowers, but the prior art does not disclose that the vase solution can produce a good life prolonging effect on Chinese roses. The formula of the vase solution has large difference aiming at different cut flower varieties, for example, the effect generated by adding sucrose in the vase solution is closely related to the concentration of sucrose and the cut flower varieties, the optimal sucrose concentration required by different cut flowers is different, the same sucrose concentration can generate an accelerating effect on one cut flower and possibly generate an inhibiting effect on the other cut flower. The concentration of sucrose is too low or too high, which affects the normal respiration and metabolism of the cut flowers and the water balance of the cut flowers. Therefore, improvement of the vase solution specially aiming at the Chinese rose is needed.
Furthermore, on the one hand, due to the differences in understanding to the person skilled in the art; on the other hand, since the applicant has studied a great deal of literature and patents when making the present invention, but the disclosure is not limited thereto and the details and contents thereof are not listed in detail, it is by no means the present invention has these prior art features, but the present invention has all the features of the prior art, and the applicant reserves the right to increase the related prior art in the background.

As shown in Table 1, the cut flower "snow mountain" obtained by cutting a bottle using the cut rose vase solution of the present example had an average vase life of 7.2 days.
TABLE 1
In the control group, the cut flower "snow mountain" using the tap water had an average bottle-insert life of 5.5 days as shown in table 2.
TABLE 2
Comparing the experimental results of the experimental group in Table 1 and the control group in Table 2, the turbidity of the bottle insert liquid in the experimental group is delayed; the water absorption capacity of the cut flowers was higher than the control group daily during the bottle insertion. The service life of the vase of the experimental group is prolonged by 1.7 days, namely the service life of the vase of the cut vase of the experimental group is prolonged by 30 percent compared with that of the cut vase of the control group. The maximum diameter of the flowers in the experimental group is increased by 39% compared with that in the first day, the maximum diameter of the flowers is increased by 26.3% compared with that in the control group, and the diameter of the flowers in the bottle insert liquid formula in the experimental group is enlarged by 12.7%.
Example 2
This embodiment is a further improvement of embodiment 1, and repeated contents are not described again.
The embodiment provides a rose cut vase solution, which comprises 0.5ml/L of nano silver (effective concentration is 1 per thousand), 0.5ml/L of phenoxyethanol, 500mg/L of citric acid, 10mg/L of ascorbic acid, 5mg/L of sodium salicylate, 200mg/L of calcium chloride and 10g/L of sucrose. The average temperature of the laboratory is 22 +/-2 ℃, and the relative humidity is 60-70%.
The preparation method of the bottle insert liquid comprises the following steps: adding the components with the concentrations into tap water, and uniformly stirring until the components are dissolved to obtain the cut rose vase solution.
The cut flowers were cut in the vase solution provided in this example, and the experimental results are shown in table 3, and the vase solution is clear, and the effect of promoting the water absorption of the cut flowers is better than that of example 1. The average life of the cut rose flower "snow mountain" was 8.8 days, and the life of the cut rose flower was extended by 60% as compared with the control group. The maximum diameter of the flower of the Chinese rose cut flower 'Xueshan' is increased by 39.1% compared with that of the first day and by 26.3% compared with that of the control group, and the diameter of the flower under the formula of the bottle insert liquid of the experimental group of the embodiment is enlarged by 12.8%.
TABLE 3
Comparing the experimental results of the experimental group in table 3 and table 1 with the experimental result of the control group in table 2, it can be seen that the concentrations of phenoxyethanol and citric acid in the cut rose flower solution are increased, the water absorption capacity of the snow mountain of the cut rose flower can be further increased, the maximum diameter of the flower is increased, wilting and turbidity of the cut rose flower solution are delayed, and the cut rose flower vase life is prolonged.
Example 3
The embodiment provides a Chinese rose bottle insert liquid, which comprises nano silver (with effective concentration of 1 per thousand) with concentration of 0.5ml/L, phenoxyethanol with concentration of 1ml/L, citric acid with concentration of 500mg/L, ascorbic acid with concentration of 10mg/L, sodium salicylate with concentration of 5mg/L, calcium chloride with concentration of 200mg/L and sucrose with concentration of 10 g/L.
The preparation method of the cut rose vase solution comprises the steps of adding the components with the concentrations into tap water, and uniformly stirring until the components are dissolved to obtain the cut rose vase solution.
The cut flower in the vase solution vase provided in this example was used, and the experimental results are shown in table 4, which improves the water absorption capacity of the cut flower of rose "snow mountain". The average life of the cut rose flower "snow mountain" was 7.7 days, and the life of the cut rose flower was extended by 40% as compared with that of the control group. The maximum diameter of the flower of the Chinese rose cut flower 'Xueshan' is increased by 27.2% compared with that of the flower in the first day and is increased by 26.3% compared with that of a control group, and the diameter of the flower is enlarged by 0.9% according to the formula of the bottle insert liquid of the experimental group.
TABLE 4
Comparing the formula and experimental results of examples 1, 2 and 3 with those of the control group, it can be seen that when the concentration of phenoxyethanol in the bottle insert liquid is increased to 1ml/L, the phenoxyethanol concentration should not exceed 1ml/L because the phenoxyethanol will produce some toxic and side effects on the stems and leaves, the stems will be discolored slightly seriously, and the leaves will be dried.
Example 4
The embodiment provides a Chinese rose cut flower vase solution, which comprises nano silver (with effective concentration of 1 ‰) with concentration of 0.5ml/L, phenoxyethanol with concentration of 0.5ml/L, citric acid with concentration of 500mg/L, ascorbic acid with concentration of 50mg/L, sodium salicylate with concentration of 5mg/L, calcium chloride with concentration of 200mg/L, and sucrose with concentration of 20 g/L.
The preparation method of the rose cut vase solution comprises the following steps: adding the components with the concentrations into tap water, and uniformly stirring until the components are dissolved to obtain the cut rose vase solution.
The cut flower of the vase solution provided in this example was used, and the experimental results are shown in table 5, and the water absorption capacity per day of the cut flower of rose "snowy mountain" was close to that of example 2. The average life of the Chinese rose cut flower snow mountain is 9 days, which is 63 percent longer than the 5.5 days of the control group. The maximum flower diameter of the Chinese rose cut flower 'Xueshan' is increased by 43% compared with that of the first day, and the bottle insert liquid formula of the experimental group enlarges the flower diameter of 16.7% compared with the increase of 26.3% of the control group.
TABLE 5
Comparing the test results of example 2 and example 4 with those of the control group, it is found that the water absorption of example 4 is not much different from that of example 2, but the flower diameter is larger, by increasing the concentrations of ascorbic acid and sucrose in the bottle-insert liquid. Sucrose is one of the respiratory substrates necessary for the cut flower to maintain normal life activities, and has certain effects of maintaining osmotic pressure, promoting patency and maintaining flower color. The addition of the sucrose in the vase solution can effectively enhance the water absorption capacity of the branches of the cut-flower Chinese rose, increase the fresh weight of the branches, increase the diameter of the flowers and improve the ornamental performance of the Chinese rose cut-flower.
The formulation concentrations of the vial inserts of examples 1-4 are shown in Table 6:
TABLE 6
Comparing the experimental results of the experimental groups of example 1, example 2, example 3 and example 4, it can be concluded that: the formulation of the bottle insert liquid of example 4 has the best effect of promoting the opening of the flower of the cut rose flower "snow mountain" and prolonging the life of the cut rose flower "snow mountain", and prolongs the life of the cut rose flower "snow mountain" by 63% as compared with the control group; the maximum diameter of the cut Chinese rose flower is enlarged by 16.7 percent. Comparing the experimental results of the experimental groups of example 4 and example 2, it can be seen that example 4 increases the amount of sucrose and ascorbic acid in the formula of the vase solution without significantly decreasing the amount of water absorbed, and can enlarge the open diameter of the flower and prolong the vase life of the cut flower. Comparing the experimental results of the experimental groups of example 3, example 1 and example 2, it can be seen that increasing the dosage of phenoxyethanol and citric acid can promote the water absorption of the cut rose flower 'snow mountain', but the concentration of phenoxyethanol is not more than 1ml/L, and may cause toxic and side effects on the cut rose flower 'snow mountain'. As shown in fig. 1, which is a line graph showing the change rate of flower diameter of the rose inserted in the vase of the rose cut vase using the formula concentration of examples 1-4, the change rate was calculated based on the diameter of the flower on the first day, and then the diameter of the flower on each day compared to the first day. As can be seen from fig. 1, the bottle inserts of the experimental groups of examples 1 to 4 all increase the diameter of the flower of the cut rose flower, i.e. increase the openness of the cut rose flower, wherein the increasing effect of example 4 is the best, and then the increasing effect of example 1 and example 2 are in sequence, and the increasing effect of example 3 is worse than that of the other examples, but also reaches 35.3%, which is increased by 9% compared with the control group.
FIG. 2 is a line graph showing the water absorption of the rose in the fresh weight per gram of the day in grams of water absorbed in the "snow mountain" using the rose cut vase solution bottle of the formula concentrations of examples 1-4. As can be seen from FIG. 2, the cut flower vase solutions of examples 1 to 4 all increased the water absorption capacity of the cut rose flowers. The water absorption promoting effect of the roses was the best in examples 4 and 2, and next to example 3, the water absorption promoting effect was better in the first 5 days of example 3, but the water absorption effect was worse after 5 days. Example 1 was inferior to the other examples, but water absorption of the cut flower rose was still promoted compared to the control group.
Example 5
The nano silver is used as a bactericide, and can cause common components of microorganisms to be destroyed or cause the microorganisms to generate physiological dysfunction after the contact reaction with bacteria, fungi, yeasts, algae, viruses and the like. When a trace amount of silver ions reach the cell membrane of the microorganism, the silver ions can be firmly adsorbed on the cell membrane of the microorganism by virtue of coulomb attraction because the cell membrane of the microorganism is negatively charged. Silver ions can penetrate cell walls to enter cells and react with SH groups to solidify proteins of microorganisms, destroy the activity of cell synthetases and make the cells lose division and proliferation capacity and die. Silver ions can also destroy the electron transport system, respiratory system, and mass transport system of microorganisms, among others.
The nano silver can also relieve the adverse effect of ethylene on the cut flowers so as to delay the aging of the cut flowers. The nano silver is added into the cut flower vase solution, so that the activity of antioxidant enzymes (SOD and POD) in cells of the fresh cut flowers and the stability of cell membranes can be improved, and the water absorption and water balance maintaining capability of the fresh cut flowers is also improved.
The low-concentration calcium can influence the biosynthesis of ethylene through the calmodulin, so that the aging of the cut flowers is delayed by matching with the nano-silver. The water absorption capacity of the flowering branch can be enhanced by using the calcium chloride solution bottle to cut the Chinese rose cut flower, the fresh weight of the flowering branch is increased, the openness degree of the cut flower is increased, and the bottle cutting life is prolonged.
The embodiment provides a method for using a rose cut flower vase solution, which uses a specific cut flower vase capable of slowly releasing nano silver or a liner of the cut flower vase to carry out flower arrangement.
When nano silver is used as a bactericide in cut flower vase solution, the nano silver is easy to generate photo-oxidation or react with chlorine in tap water to generate insoluble precipitates, so that the bactericidal effect is lost. Most of the existing vases are transparent glass vases, have no shading capability, and can lead the nano silver in the vase solution to be photolyzed after being placed for a long time; and the mode of adding nano silver once has good sterilization effect in a short time, but the quantity of a small amount of live bacteria which are not killed by the nano silver initially after long-term placement and remain in the bottle insert liquid increases to a larger order of magnitude after continuous logarithmic growth, and at the moment, the nano silver fails to inhibit the growth of bacteria due to long-term placement, so that the quantity of microorganisms in the bottle insert liquid is difficult to be limited by the nano silver for a long time.
The cut flower vase inner container used in the using method of the rose cut flower vase solution provided by the embodiment is made of an inflatable structure, can be placed into a vase in a contracted state, adapts to the shape of the vase after being inflated, is attached to the inner wall of the vase, and is stably connected with the vase through a fixing structure. Preferably, the fixing structure can be a limiting structure arranged at the vase mouth or a limiting part arranged on the vase liner close to the vase mouth. The inner container forms an accommodating space capable of accommodating the vase solution and the stem of the flower when being fixed in the vase. The inner wall of the inner container is also provided with a slow release structure capable of slowly releasing the nano silver, as shown in fig. 3, the slow release structure sequentially comprises from inside to outside: the first layer 1, the second layer 2 and the third layer 3, which sequentially form a sandwich structure. The second layer 2 is used for containing activated carbon particles adsorbed with nano silver. The third layer 3 is arranged to be the layer closest to the outer wall of the vase, and the layer is made of a material with light shading performance into a dark color so as to shade the nano-silver particles in the second layer 2 from light and avoid photolysis of the nano-silver particles. The first layer 1 is the layer closest to the central axis of the annular vase liner, the layer is provided with a pore communicated with the second layer 2 and the vase solution, most microorganisms in the vase solution and the vase solution can pass through the pore, and the vase solution and the microorganisms contained in the vase solution can freely contact with the activated carbon in the second layer 2 through the pore so that the nano silver adsorbed by the activated carbon in the second layer 2 contacts with the vase solution to kill the microorganisms.
The using method of the vase liner comprises the following steps: firstly, adding activated carbon particles adsorbed with nano-silver into an activated carbon layer of the vase liner, then putting the vase liner into a vase, and inflating to enable the vase liner to be matched with the shape of the vase and be fixed; and then adding the prepared vase solution into the accommodating space of the vase liner to the height of the submerged slow-release structure. Shaking the vase to enable vase solution in the vase to repeatedly pass through the interior of the three-layer sandwich slow-release structure, enabling the vase solution containing microorganisms to firstly pass through the first layer 1 and enter the activated carbon layer to impact the activated carbon particles, enabling the nano silver particles adsorbed in the activated carbon particles to be released, enabling the released nano silver particles to be in contact with the microorganisms in the vase solution and kill the microorganisms, then enabling the vase solution without the live microorganisms to pass out of the first layer 1 based on shaking of the vase, and enabling the nano silver particles to be partially retained in the slow-release structure due to blocking of the first layer 1 so as to sterilize the vase solution entering the slow-release structure next time. The microorganisms in the vase solution repeatedly contact with the nano silver particles released from the slow-release structure and are killed, and the number of microorganisms with reproductive capacity in the vase solution is reduced after the microorganisms are repeatedly shaken, so that the influence on the water absorption performance of the cut flowers caused by the blockage of guide pipes of the cut flowers after the microorganisms are massively propagated is avoided. Preferably, the third layer 3 of the vase or the slow release structure close to the outer wall of the vase is provided with a dark sponge layer to shade the nano-silver adsorbed in the activated carbon layer inside, and meanwhile, the structure of the activated carbon particles can also play a role in shading the nano-silver particles adsorbed in the activated carbon particles, so that the nano-silver can be stored in the vase solution for a long time, and the nano-silver photolysis consumption is avoided. After the vase solution is used for arranging flowers for 1-2 days, the nano silver particles adsorbed in the activated carbon and not released can be released again by shaking the vase again, and the vase solution is repeatedly contacted with the vase solution based on shaking to sterilize the vase solution again. A small amount of microorganisms which are not killed in the first shaking grow to a certain amount again after logarithmic growth for 1-2 days, at the moment, the nano silver is contacted with the currently alive microorganisms through the shaking to kill the microorganisms so that the survival amount of the microorganisms in the vase solution is reduced to a lower level again, compared with a mode of adding the nano silver at one time, the microbial amount in the vase solution can be controlled for a long time, the microbial amount for 2-3 days is obviously reduced, the volume of the killed microorganisms is reduced after disintegration, and the possibility that the microorganisms block a cut flower duct is reduced. The fungus quantity in the bottle insert liquid can be kept at a lower level by repeating the steps, so that the possibility that the fungus blocks the cut flower guide pipe is reduced, the water absorption performance of the cut flower is improved, and the service life of the cut flower is prolonged; the utilization rate of the nano silver can be improved; the operation is simple.
Rose cut vase data using the liner of this example using the formula of the vase solution of example 1 are shown in table 7:
TABLE 7
Comparing the results in table 7 with the experimental results of the control group and example 1, it can be seen that the water absorption of the cut flower vase using the vase liner of this example was significantly improved as compared with example 1. The maximum diameter of the cut flower is enlarged by 38%, which is increased by 26.3% compared with the control group, and the maximum diameter of the cut flower vase-inserted into the vase inner container of the present embodiment is enlarged by 11.7%. The service life of the test group is prolonged by 45% compared with the control group for 5.5 days by 8 days.
According to the experimental data, the cut rose flowers inserted into the vase inner container bottle of the embodiment can help to kill microorganisms in the solution, prevent the microorganisms from blocking the conduit of the cut rose flowers, increase the water absorption capacity of the cut rose flowers and prolong the vase life of the cut flowers.
