[0027] The autumn flowering method of embodiment 1 peony 'Ao Shuang'

[0028] At the beginning of July 2009, cut off the remaining flowering branches, useless branches, sick branches, and dead branches on the top of the branches of the 'Aoshuang' plant, and at the same time apply compound fertilizer to the soil and roots. On August 15th, 2009, the test plants were defoliated by artificial defoliation of the whole plant. One week after the defoliation treatment, a total of 14 'Aoshuang' plants were divided into two groups, and one group was treated with 500mg / L GA 3 Smear the terminal buds of the plants, and the other group smears the terminal buds of the plants with clear water, once every other day, for a total of 3 times. After the flower buds germinate, spray on the surface of the leaves with 0.2% potassium dihydrogen phosphate every week, and water once every 10 days. Around October of that year, the flowering performance of the peony 'Aoshuang' treated with gibberellin ...

[0031] The autumn flowering method of embodiment 3 peony 'Ao Shuang'

[0032] On July 5, 2009, cut off the flowering branches remaining on the 'Aoshuang' plants, as well as useless branches, sick branches, and dead branches on the top of the branches, and compound fertilizer was applied to the soil and roots at the same time. On August 15, 2009, 80% of the leaves of the whole plant were removed from the test plants. After 10 days of defoliation treatment, the 'Aoshuang' plants were treated with 300mg / L GA 3 Apply to the terminal buds of the plants, once every other day, for a total of 2 times. After the flower buds germinate, spray on the surface of the leaves with 0.3% potassium dihydrogen phosphate every week, and water once every 10 days. Around October of that year, the treated peony could bloom, the flowering rate of the plants was 80.31%, and the flowers and leaves were well developed when blooming, while the peony 'Aoshuang' without the above treatment could not bloom...
