Heze peony cultivation began in the Southern Song Dynasty and flourished in the Ming and Qing Dynasties. After liberation, it developed rapidly, especially after the Third Plenary Session of the Eleventh Central Committee. Heze peony flower is big, colorful, beautiful and fragrant, and it is the top grade of ornamental peony. Looking at its appearance, there are three kinds (single petal, double petal and thousand petals), six kinds (sunflower, lotus, rose, hemisphere, crown and hydrangea) and nine color systems (red, white, pink, yellow, purple, blue, black, green and multicolor), among which black peony and green peony are the most rare. However, Heze people who have been closed for a long time have always regarded peony as medicinal materials and ornamental flowers, but have not promoted peony as a commodity, let alone developed peony as an industry. From 65438 to 0992, with the approval of the State Council, Heze held the first International Peony Fair. Tens of thousands of Chinese and foreign guests witnessed the "blooming peony" in Heze and discussed economic and trade cooperation. The 9th Heze International Peony Fair has been held, and the export turnover alone reached more than 654.38 billion US dollars. At present, Heze Peony has accounted for 85% of domestic sales. Heze peony strutted towards the international market.
Holding a flower party has broadened the horizons of Heze people and developed the flower industry with peony as the pillar industry. They invited experts and professors to re-plan and design the Peony Garden according to the principle of combining arbor, shrub and grass and paying attention to the construction style of external gardens. With the peony office as the center, the square garden is planned to be a peony industrial zone of 35 square kilometers. More than 10 townships have planted peony in a large area, with an annual growth of 1 10,000 mu. Peony resource garden and peony gene bank have also been established rapidly. At the same time, cooperate with China Academy of Agricultural Sciences, Beijing Forestry University and other universities and scientific research units to increase the research and development of peony. Major breakthroughs have been made in scientific research topics such as peony flower forcing, fresh cut flowers, variety breeding, soilless culture and tissue culture. The flowering of peony in four seasons has become a reality, and the technology of bud grafting and rapid propagation has been popularized. Heze Peony with high-tech content won two world awards and 79 gold, silver and bronze awards in one fell swoop at the 99 Kunming World Horticultural Exposition in China, accounting for 73.2% of the total number of awards, thus establishing the world dominance of Heze Peony. Peony flowers have become the most dynamic economic growth point in Heze.
