Abstract

The invention relates to cutting flower fresh-keeping technology, and provides a preparation method and inhibitor for suppressing fresh cutting flower aging using sodium nitroprusside as main material. The inhibitor consists of sodium nitroprusside, dispersant, damping agent, stabilizer and stuffing, each ingredient being in mass percent : sodium nitroprusside 60-80%, dispersant 2.0-5.0%, damping agent 0.5-5.0%, stabilizer 1.0-2.0% , balance being stuffing. The preparation method of the inhibitor adopt attritioning technique. The inhibitor of the invention for suppressing cutting flower aging can delay the aging, adjust the growth and development after cutting, and prolong the shelf life of cutting flower, reduce the damage when in storing and transport.

Description

technical field [0001] The invention relates to a fresh-keeping technology for cut flowers, more specifically, relates to a cut flower senescence inhibitor with sodium nitroprusside as a main raw material and a preparation method thereof. Background technique [0002] After the cut flowers leave the parent body, due to mechanical damage, lack of nutrient and water supply, there will be a physiological response of aging. In plants, ethylene plays a regulatory role in various growth phenomena. The senescence of cut flowers will lead to the production of endogenous ethylene, and exogenous ethylene will also promote the senescence of cut flowers. [0003] The commonly used preservatives for cut flowers are mainly composed of fungicides, carbon sources and ethylene inhibitors. Chinese Patent Publication No. 1009834 provides a fresh-keeping agent for cut flowers, which mainly contains sucrose, 8-hydroxyquinoline, citric acid, silver nitrate, aluminum sulfate, potassium dihydroge...
