Abstract

The invention belongs to the technical field of flower preservation, in particular to a cutflower preservative using a polypeptide and 1-methylcyclopropene as main components, which is prepared by dissolving and mixing the polypeptide, 1-methylcyclopropene, sucrose, citric acid, ethanol and water, wherein the polypeptide is one which is homologous to polyaspartic acid and has a average molecular weight of 3000-5000. By using the polypeptide homologous to polyaspartic acid and the 1-methylcyclopropene which is completely biodegradable, the invention overcomes the disadvantages of high physiologic toxicity, large possibility to pollute the environment and the like of the existing preservative, has the characteristics of good preservation effect, no pollution and the like, and can effectively prolong the preservation time of the cutflower.

Description

technical field [0001] The invention belongs to the technical field of flower preservation, and in particular relates to a fresh-cut flower preservation agent mainly composed of polypeptide and 1-methylcyclopropene. Background technique [0002] The extension of fresh-cut flower preservation period has a significant effect on improving the ornamental value and commercial value of fresh-cut flowers. It has become a relatively active research field in horticultural science and one of the key technologies in the flower industry. [0003] At present, the common fresh-cut flower preservation is mainly based on chemical preservation. The commonly used inorganic salts in preservatives mostly use silver salts (such as silver thiosulfate STS), but Ag + High physiological toxicity, will seriously pollute the environment. Polyacrylic acid (sodium) contains a large number of carboxyl hydrophilic groups, has strong water absorption and water retention functions, and can maintain a high ...
