The invention discloses a peony
cut-flower single-color and compound-color
dyeing method which comprises the following steps: (1) preparing a
dyeing solution, namely preparing a
food coloring into the
dyeing solution by using a
trehalose solution, and immediately preparing for use; (2) flower
cutting pretreatment:
pruning flowering branches with the length of about 30cm, leaving two compound leaves below the flowers, obliquely
cutting the lower ends of stalks at 45 degrees, and immersing the stalks into a
staining solution with the depth of 5-8cm; and (3) dyeing: performing single-color dyeing for 104-193 minutes, taking out the Chinese herbaceous peony to obtain the single-color-dyed Chinese herbaceous peony
cut flower, taking out the Chinese herbaceous peony until the color is unchanged, directly inserting the Chinese herbaceous peony into another dyeing solution until the color is uniform, and taking out the Chinese herbaceous peony
cut flower to obtain the compound-color Chinese herbaceous peony cut flower. After being dyed, the Chinese herbaceous peony cut flower obtained by the dyeing method is stable and bright in color, more natural in color fusion, more uniform in overall color, better in ornamental effect and more diversified in applicability, and production and consumption can be promoted. And moreover, the ornamental period required by the
cut flowers can be reached, and the practical commercial value is achieved.
