摘　　要：在黑龙江省东南部地区的海林市进行紫斑牡丹[Paeonia rockii(S.G.Haw et L.A.Lauener)T.Hong et J.J.Li]苗木的栽培试验,连续3年对紫斑牡丹的生长发育表现、物候期进行了观测,采用不同防寒措施进行对比试验。结果表明,紫斑牡丹苗木部分植株地下根系不做防寒处理能正常越冬,但地上枝条冻害严重,保存率逐年降低,长势弱,每年生长量不明显;物候期与原产地相比均较晚;采用不同防寒措施对其萌芽期和始花期影响较大,对其成活率也有一定影响。The cultivation test of Paeonia rockii（S.G. Haw et L.A. Lauener）T. Hong et J. J. Li seedlings which was introduced into southeastern region of Heilongjiang rovince, Hailin. was conducted for 3 consecutive years to observe the growth performance and phenology. And comparative test of different cold proof measures was carried out. The results showed that partial plants of the roots of P. rockii seedlings could normally pass through the winter without cold treatment; but the freeze injury of branches was serious as the preservation rate decreased year by year; the growth was weak while annual growth was not obvious. The phenophase was later compared with the origin. Different cold treatment had different effects on germination period and initial flowering period, also had certain effects on the survival rate.
