Method for prolonging refreshing time of borage flowers

Abstract

The invention discloses a method for prolonging the refreshing time of borage flowers. The method comprises the following steps: (1) immersing the borage flowers into a sodium alginate solution, then taking out the borage flowers, and draining the residual sodium alginate solution; and (2) immersing the borage flowers into a calcium chloride solution to induce spontaneous cross-linking reaction, then taking out the borage flowers and absorbing moisture on the surfaces of the borage flowers. The preservation time of the borage flowers treated by the steps (1) and (2) is 5-6 days and is 4-5 days longer than the preservation time of untreated fresh cut flowers. The method comprises the step (3) that the borage flowers are inserted in a fresh-keeping solution, wherein the fresh-keeping solution is prepared from a bactericide, a nutritional agent, an ethene antagonist, a plant growth regulator and the like, so the aging of the borage flowers can be further slowed down, the vase life of the cut flowers can be prolonged, and the ornamental quality of the cut flowers can be improved. The preservation period of the borage flowers treated by the steps (1), (2) and (3) is 10-15 days and is 9-14 days longer than that of untreated fresh cut flowers, and a relatively high water activity value can be maintained.
