Embodiment 1

[0125] Select three-year-old peonies 'Qihualushuang', 'Liantai' and other varieties, and put them into pots on October 18. In the Huanghuai area, they can be placed outdoors, watered once every half a month, and stop watering when the temperature drops below 0°C . On January 22, it was placed in a cold storage at -3°C to 0°C, with a humidity of 70%-90%. Leave the warehouse on April 5 and enter the greenhouse (daytime temperature 25°C, night temperature 10°C). 'Qihualushuang' blooms from May 20th to May 28th, and 'Liantai' blooms from May 22nd to May 30th.

Embodiment 2

[0127] Select late-flowering varieties such as 'Peach Blossom Feixue', 'Dahongkui', and 'Yang Fei Chuyu', and put them in pots on October 15th. The Huanghuai area can be placed outdoors, watered once every half a month, and the temperature drops to Stop watering when the temperature is below 0°C. On January 30, it was placed in a -3°C to 0°C freezer. On April 21, it will leave the warehouse and enter the greenhouse (daytime temperature is 25°C, night temperature is 10°C), and it will bloom on June 5th, and the flowering period is from June 5th to June 20th.

Embodiment 3

[0129] Select late-flowering varieties such as 'Peach Blossom Feixue', 'Dahongkui', and 'Yang Fei Chuyu', and put them in pots on October 15th. The Huanghuai area can be placed outdoors, watered once every half a month, and the temperature drops to Stop watering when the temperature is below 0°C. On January 30, it was placed in a -3°C to 0°C freezer. It leaves the warehouse and enters the greenhouse on May 1 (daytime temperature is 25°C, night temperature is 10°C), and blooms on June 15th.
