Abstract

The invention relates to a peony cut-flower forcing culture method. The method comprises the following steps of: selecting 3 to 4-year peony plants with plump flower buds, refrigerating seedlings for 30 to 60 days at the temperature of 0 and 4 DEG C to remove flower bud dormancy, and then spraying liquid to the roots of the seedlings; potting the seedlings, spraying 200 to 500mg/L gibberellin solution to each pot, and then culturing the seedlings for 60 to 90 days in a greenhouse; and when the sprouts are grown to 5 to 10 centimeters, properly removing bud-free sprouts, and finally cutting the flower branches from the roots. The method has the advantages of solving the problems of requirement of conventional flower forcing peony for cold storage area and cut-flower quality influenced by stunted flower forcing peony plants and poor flowering quality and the like, greatly improving the appreciation value and commodity value of the cut-flower peony and providing basis for standardized production, along with simple operation and lower cost.
