摘要
"芍药南移"是经典的观赏园艺学问题,长期受到理论关注,但相关实践却非常有限。芍药的大花、单花、阔叶的特性,在江南地区园林应用中有重要价值,值得大力推广。但因冬季需冷量不足导致开花量少、春季高温徒长引发花朵"垂头"、夏季高温多湿带来严重热害涝害等诸多原因,导致"芍药南移"步履维艰。充分利用杭白芍等江南地区的优良本土资源,培育具备低需冷量、花朵复瓣程度低、花茎粗壮缩短、抗湿热能力强等性状的江南芍药品种,并进行育种、扩繁、包装、销售为一体的产业化生产,是实现"芍药南移"的主要手段。
The Southward Plantation of Paeonia lactiflora is a classic problem of ornamental horticulture, which has been paid muchattention in theory for many years, but lacked of scientific practice. Paeonia lactiflora has the single-big-flowers and broad-leaves,plays particular roles in flower border design in south region of the Yangzi River. However, the lack of chilling requirement leads to itsfewer flowers, the high temperature in spring results in its drooping flowers, and the muggy climate in summer generates the seriouswaterlogging and heat damage for Paeonia lactiflora in Jiangnan Region. All these obstacles seriously hinder the southward plantation ofPaeonia lactiflora . We should take full advantage of local superior germplasm resources, such as cultivated Hangbaishao Peony, to breednew Jiangnan cultivars which have low chilling requirement, relatively simple flower type, short-strong flower stem and strong heat andhumidity resistance. We should also try to accomplish the industrialization produce for Paeonia lactiflora . These measures will help toultimately achieve the Southward Plantation of Paeonia lactiflora .
