| Herbaceous peony (Paeonia lactiflora Pall.) is a kind of traditional flowers in China, and also is very famous in Shandong, which has very high aesthetic values and is widely applied in landscape garden. In recent years, with the development of application and commodity economy of flowers, herbaceous peony also has showed the potential of being a commodity. But at the present time, herbaceous peony has never entered into markets whether cut-flowers or pot-flowers. This mainly due to two reasons: on the one hand, many cultivars have no specific orientation, thereby they can not be produced specifically; on the other hand, the techniques of protected cultivation are not advanced, so they can not be produced all the year round or multiple seasons.Therefore, this research was based on the general survey of herbaceous peony cultivars and the selected results of specific cut-flower and pot-flower cultivars. These cultivars were cultivated in a greenhouse, from which further selection of cultivars suitable for cultivation in greenhouse were chosen. At the same time, a number of matched measures of cultivation techniques were explored.The research was carried out for 2 times, the first time to select cultivars initially, the second time to further select and verify the first results, and to summarize the matching cultivation techniques. The main conclusions were as follows:1. The cultivars suitable for cultivation in greenhouse were selected after two tests.'Da Fu Gui'﹑'Lian Tai'﹑'Fen Yu Nu'were suitable to pot-flower cultivation in greenhouse;'Lan Hai Bi Bo'﹑'Yang Fei Chu Yu'were suitable to cut-flower cultivation in greenhouse.2. Cold storage could break dormancy of herbaceous peonies and promote germination, for'Da Fu Gui'and'Lian Tai', the effective treatment time were 5 weeks and 6 weeks separately.3. The effection of GA3 on phenophase of three cultivars was studied. GA3 could significantly promote bud sprouting, and it could break dormancy which substituted the role of low temperature. There were differences among different cultivars, for'Da Fu Gui'and'Lian Tai', the most effective concentration was 300mg/kg; but,for'Zi Feng Yu', 200mg / kg was most suitable.4. The impact on the dwarf cultivation of herbaceous peony was investigated in'Zi Feng Yu'by paclobutrazol (PP333). The results showed that paclobutrazol had significant role in the promotion of dwarf, and the effective concentration was 200 ~ 250 mg / kg.5. The growth and development process of herbaceous peonies cultivated in the greenhouse were recorded. The phenophase was divided into six stages: bud sprouting phase﹑scale cracking phase﹑stem elongating phase﹑leaf expanding phase﹑blossom expanding and showing color phase﹑flowering phase. Each phenophase was defined as a period of time: the beginning of a period to 60% of buds or stems in this period of time.6. For herbaceous peony cultivars tested, the matching techniques of cultivation in greenhouse were summed up, and the technical process of greenhouse cultivation system was described, which included the basin, dormancy, environmental management in greenhouse, and some consultative suggestions were supplied, which could supply reference for future research and production.
