The invention discloses a method for prolonging flowering periods of potted flowers and
cut flowers of
cymbidium ensifolium. The method comprises the following steps: (1) preparing a 1-MCP
medicine bag; (2) preparing a mixed preparation of 6-BA and KH2PO4; (3) potted flower treatment: uniformly spraying a mixed preparation on leaf surfaces until water drips from the leaf surfaces;
wetting the 1-MCP
medicine bag with clear water, putting the 1-MCP
medicine bag into the base part of the potted
plant, sealing and fumigating at the same time, removing the sealed potted
plant, and putting the potted
plant in a cool and ventilated place; and (4)
cut flower treatment: firstly putting the scapes into a plastic tube containing the mixed preparation, then putting a frame containing the built orchid scapes into a sealing box, then
wetting the 1-MCP medicine bag with clear water, putting the 1-MCP medicine bag into the sealing box, simultaneously sealing and fumigating, taking out the
cut flowers after fumigating treatment, and putting the
cut flowers in a cool and ventilated place. The method is easy to operate and control, low in cost, good in
repeatability, suitable for being applied to production of potted flowers of
cymbidium ensifolium and preservation of
cut flowers, and capable of effectively reducing
ethylene synthesis in the flowers, delaying
senescence, prolonging the blooming time and improving the overall quality of the
cymbidium ensifolium.
