As the traditional flowers, peony has a broad market prospect. In this paper, the Daejeon primary peony varieties of potted material, A pot experiment was to study the cultivation methods peony growth, flowering, selection of suitable potting study released peony sleep low temperature, and potted peony some of the key The cultivation techniques discussed, including different nutrient solution, cultural environment, removal of lateral bud, winter peony growth, flowering, potted peony varieties Filter On this basis, aims to provide a reference for the peony potted. The results are as follows: (1) cultivation methods on peony growth, flowering have a significant effect. The garden soil potted peony growing weak, poor flowering, Daejeon planted peony growth, flowering better. (2) initial screening is more suitable for the growth of potted peony matrix peat: vermiculite: perlite = 3:1:1. The ③ trials with different nutrient solution has little effect on on the potted peony plant height and crown, flowering flowering rate. Application of fertilizer most conducive to the growth of the peony blossom. Potted peony leaves of nitrogen, phosphorus and potassium, the same trend, long-term increase from infancy to stem elongation, stem elongation has been a downward trend. Matrix nitrogen, available phosphorus overall dynamic change trend is the same, but the K content has been relatively stable. Throughout the growing season potted peony nitrogen uptake and consumption is greater than the phosphorus and potassium. Infancy to stem elongation is a critical period (4) cultivation environment potted peony fertilization significant impact on a potted peony plant height and crown, facing the amount of flowers and flowering rates have a significant effect. All varieties grown in outdoor conditions, better flowering. Temperature and humidity affect the growth of greenhouse and outdoor peony flowering important factor. (5) removal of the side bud potted peony plant height and crown, flower diameter size and flowering rate had no significant effect. Go to the side of the bud plant with large flowers, the groups long flowering period, should be retained in the production side of the bud. (6) potted peony in Beijing outdoor open to place the safety of winter, but the peony in a ditch film, cover straws more conducive to the growth and flowering of plants in the coming year. (7) After the initial groping, found excessive amount of low temperature will reduce the rate of peony bud and flowering rate. Gibberellin can make the peony early germination, and promote the growth of plant height and flower buds, improve the the bud rate and flowering rate. However, when the low temperature reaches a certain amount, GA treatment is not conducive to plant growth and flowering. 7.2 ° C model, the low temperature of 823 hours to break the 'rich' Sleep, plant growth and flowering. ⑧ compared with other varieties, 'the rich' in the greenhouse remains low, compact plant with large flowers, flowering rate, the groups long flowering period, robust growth characteristics, is suitable for potted peony varieties.
