Description
Technical Field
The invention relates to the technical field of flower preservation, in particular to a peony and Chinese herbaceous peony fresh cut flower preservative and a preparation method thereof.
Background
The fresh cut flower is an organ of branches, leaves, flowers, fruits and the like of in-vitro flowers, can generate a series of physiological changes after being picked and cut, is easy to age and deteriorate and decay, the loss rate after being picked is about 20 percent, the fresh cut flower product is viewed and admired, the service life of the vase fresh cut flower is usually only 3 to 10 days, and the commodity value of the cut flower is seriously influenced. In order to maintain the best quality of the cut flowers after being picked, delay aging and resist the rapid change of the external environment, chemical agents can be adopted for treatment to regulate or relieve the physiological barriers of the cut flowers after being separated. The reasonable use of the fresh cut flower preservative is very important, the preservative not only plays a role in sterilization and corrosion prevention, but also can promote the water absorption of flower stems, increase nutrition, prevent petals from falling off, enable the flowers to be enlarged and the flower colors to be bright, enable the leaves to be bright green, enable the stems to be tall and straight, obviously improve the quality and the commodity value of the fresh cut flowers, prolong the bottle inserting time, and generally prolong the preservation period by 2-3 times compared with the non-treated cut flowers.
Peony belongs to deciduous shrubs of Paeonia of Paeoniaceae, and is one of ten traditional flowers in China. As a famous and precious flower, the peony blooms intensively, the flowering phase is short, the flower is large and bright, the fragrance is strong, and the market benefit is extremely high. The peony derivative product-peony cut flower has quick decay after the peony cut flower is separated from the parent body. The decline and death of isolated organs of plants are mainly influenced by the following factors: (1) water is absent; (2) insufficient supply of organic nutrients, vitamins and mineral elements; (3) is damaged by the release of ethylene, while peony is more sensitive to ethylene; (4) cutting the trimmed mechanical damage; (5) infection by harmful microorganisms; (6) the temperature, humidity, illumination, ventilation and other external environments are changed after separation; (7) uncontrolled endogenous hormones, etc. These factors contribute to each other and are also mutually restrictive. However, if the conditions are improved, the progression of the senescence death is retarded to a different extent. The method can correctly master the fresh-keeping technology of the peony cut flower, prolong the ornamental value and enhance the ornamental effect.
Therefore, the technical problem to be solved by the technical personnel in the field is how to provide a peony fresh cut-flower preservative which is non-toxic, economical, convenient and fast and can prolong the ornamental time of cut-flowers and a preparation method thereof.

Comparison of flower stems of fresh cut flowers of peony treated differently
The maximum diameter of each flower was measured twice by a cross measurement method with a vernier caliper at about 16: 00 per day, and the average value was taken. The flower diameter is not measured when half of each repetition loses ornamental value, and the detection result is shown in table 2.
Change in flower diameter (%) (maximum diameter of each flower per day during vase period)
Average-initial flower diameter)/initial flower diameter x 100
