摘　　要：以芍药品种‘蓝海碧波’(Paeonia lactiflora‘Lan Hai Bi Bo’)四年生分株苗为试材,以土壤地栽为对照,对容器栽培苗茎叶生长期、育蕾期、盛花期、根芽生长期、枯萎期的生长情况进行研究,探究容器栽培模式下芍药生长发育、干物质积累及分配规律,以期为今后芍药容器苗的生产栽培提供理论依据。结果表明:容器栽培模式下芍药冠幅、复叶数、发枝数、单株成花数与对照相比显著增加,分别提高了10.1%,92.0%,60.6%和66.7%,生长期较对照延长35 d。芍药容器苗整株、根、须根、茎、花/果的最大干物质积累量均高于对照,分别为对照的1.39倍、1.37倍、1.63倍、1.09倍和1.90倍;叶的最大干物质积累量略小于对照,为对照的95.04%。容器栽培对芍药营养器官干物质分配率无显著影响,但明显有利于花、果实器官干物质积累。容器苗花、果实的干物质分配率分别为对照的1.30倍和1.63倍。容器栽培模式使芍药‘蓝海碧波’分株苗栽植后的第一个生长季干物质积累提高,株型更丰满,开花量显著增加、观赏期显著延长,有助于获得质量较高的芍药产品,对芍药商品生产开发有一定意义。The aim of this study was to explore the effect of container growing on herbaceous peony,so as to provide the theory basis for the cultivation and management of container-raised peony. The growth,development,dry matter accumulation and distribution of container-raised Paeonia lactiflora‘Lan Hai Bi Bo＇ were investigated in 5 different growth-stages including stem and leaf growth stage,flower bud formation stage,full-bloom stage,root and bud growth stage and withering stage,and the plants in field were used as the control. The results showed that： There was a significant difference in canopy width,compound leaf number,shoot number and flower number per plant between the treatment and the control,which increased by 10. 1%,92. 0%,60. 6% and 66. 7%,respectively,than the control. Moreover,container growing significantly prolonged the vegetative period of peony by 35 days. The dry matter accumulation of whole plant,roots,fibrous roots,stems and flowers of container-grown seedlings were allhigher than the control,which were 1. 39 times,1. 37times,1. 63 times,1. 09 times and 1. 90 times,respectively,of the control. The dry matter accumulation of leaves was slightly lower than the control,which was 95. 04% of control. Container growing had no significant effect on dry matter distribution rate of vegetative organs; however,it was obviously beneficial for dry matter accumulation in flowers and fruits. The dry matter distribution rate of flowers and fruits were 1. 30 times and 1. 63 times of the control,respectively. Therefore,the growth of Paeonia lactiflora‘Lan Hai Bi Bo＇ in the first year in container growing system was increased than the control. It had more dry matter accumulation,compact plants,and its flower production,ornamental time were better than the control. Container growing is helpful to get higher quality peony products,which is beneficial for the commodity development of herbaceous peony.
