Abstract

The invention discloses a tree peony fresh cutting flower anti-staling agent which is composed of the following components in parts by weight: 2-8 parts of chitosan, 5-15 parts of calcium chloride, 5-18 parts of citric acid, 10-20 parts of polyvinyl alcohol and 1-5 parts of emulsifying agent. According to the tree peony fresh cutting flower anti-staling agent, the anti-staling agent is prepared from the chitosan, the polyvinyl alcohol, the calcium chloride, the citric acid and the emulsifying agent aiming at the characteristics that the tree peony has large petals, bright flower color and short flowering phase; when the anti-staling agent is used, the preservative solution is prepared from all the components and the preservative solution is sprayed on the surface of the petals of a tree peony fresh cutting flower to form one layer of a thin film on the petals, so as to effectively prevent water of the tree peony cutting flower from being evaporated, decrease the water loss of the petals and delay the withering caused by the water loss of flower branches; and the degradation of soluble proteins in the petals and damages to a cytoplasm membrane can be effectively inhibited, so that an ageing process of the tree peony cutting flower is delayed, the service life of the tree peony fresh cutting flower inserted in a bottle can be prolonged by 3-4 days and the quality of the cutting flower is guaranteed.
