【摘要】 针对从黑龙江牡丹江引种的56个品种332株芍药在贵州省植物园生长发育规律进行观察,记录芍药引种栽培后的生长特性。观察发现引种芍药的生育期可划分为6个阶段,芍药在贵阳地区萌发比东北早50天,花期提早45天,枯萎期推迟70天。分株苗生长期长于1年、2年的实生苗,且分株繁殖与种子繁殖相比可明显缩短开花周期。所有植株的引种成活率在95%以上,品种的引种成功率为100%。因此,建议将芍药作为贵阳地区重要的园林植物发展。更多还原

【Abstract】 In this paper,we observed the growth of Paeonia lactiflora introduced from Mudanjiang,Heilongjiang into Guizhou Botanical Garden(56 varieties,332 plants),and recorded their growth characteristics.The results show that the growing period of Paeonia lactiflora includes 6 stages.The germination time of Paeonia lactiflora in Guiyang is about 50 days earlier than that in Heilongjiang,the florescence is 45 days earlier,and the withering is postponed for 70 days.The growing period of the tillerings is longer than that of the one-year and two-year seedlings,and compared with seed propagation,division propagation could shorten the bloom cycle obviously.The surviving rate of the introduced plants is more than 95%,and the surviving rate of all the varieties is 100%.Therefore we advise that Paeonia lactiflora be promoted as a promising ornamental plant in Guiyang.更多还原
