After the dipping treatment, the flowers were taken out from the storage solution and naturally dried for 8 hours at a humidity of 30%. After the flowers are dried, the flowers, the buds and the receptacle are dried by spraying or coating with silicone resin at room temperature of 21 ℃.
After drying, compared with the example using thiourea, the thiourea is observed to be added, the pigment is lost, the similar bleaching effect of different degrees is presented to the parts such as petals, receptacles and the like, the color distortion is serious, and the thiourea can obviously prevent the pigment from being lost from flowers or buds.
In conclusion, the general flower preservation solution provided by the invention can protect the color of common flowers with different colors, is suitable for flowers which bloom as well as flowers and buds, and the flowers or the buds treated by the general flower preservation solution can not be rotten, discolored, faded and deformed when being compared with the flowers or the buds which are just picked, the color and the shape of the flowers or the buds can be kept for a long time, and the general flower preservation solution plays a good auxiliary role in dissection, observation, teaching and exhibition. The dehydrating agent in the universal fresh flower preservation solution can achieve the dehydrating effect by adjusting osmotic pressure caused by different water potentials inside and outside tissues, adjust the water content of fresh flowers to a critical value (the water content is less than or equal to 5%) which does not induce enzymatic reaction, aldehyde group sulfenic acid in the pigment fixing agent can accelerate the fixation of white parts in the flowers, simultaneously ensure that the white parts are not easy to generate dark deposits, and phosphate not only can adjust the pH value of the solution, but also can effectively fix green and blue in the fresh flowers; the common use of carbolic acid and citric acid can effectively fix red, peach red, rose red, orange and yellow, the experiment stage finds that the lack of one of the two can obviously affect the color of the flower after the treatment of the color, the use of thiourea can prevent the pigment from losing from the flower and prolong the storage time of the flower, the use of citric acid, aluminum sulfate, sodium citrate and liquid silicone can obviously prolong the storage life of the pigment fixing agent, the lack of any one of the components can influence the effective period of the fixing agent, the effective period of the pigment fixing agent containing citric acid, aluminum sulfate, sodium citrate and liquid silicone can reach 90-120 days, and the effective period of the pigment fixing agent lacking any one of the components is only 10-30 days.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent modifications made by the present invention in the specification or directly or indirectly applied to the related technical field are included in the scope of the present invention.
