摘要:
以25个观赏荷花品种为研究对象,进行水深1.8 m栽培后的生长期物候观测。结果表明:深水栽培后,有21个品种能开花,且具有一定的观赏性。按照叶柄、花柄高度,叶径、花径大小及花期长短,将21个观赏荷花品种划分为5个类群。极高叶柄类群(H>2.6 m)和极高花柄类群(H>2.8 m)品种种类相同,分别为荷花‘冬日红’、荷花‘连云港冬荷’、荷花‘金凤展翅’。其中,荷花‘连云港冬荷’的叶径、花径达到极高水平,且为长花期类群种,花期可达118 d;中等高度叶柄类群(H>2.2 m)和中等高度花柄类群(H>2.4 m)中,荷花‘红建莲’、荷花‘星空牡丹’花期分别为112,123 d,属长花期类群。深水栽培的观赏荷花,按照表型性状及数量性状进行分类,可为湿地造景提供丰富的品种选择。
Abstract:
With 25 ornamental lotus cultivars as the research object,their growth phenology was observed under deep water cultivation. The results were as follows, 21 cultivars was still flowering in deep water. According to the petiole height, flower height, flower diameter, leaf diameter and flowering duration, 21 ornamental louts cultivars were divided into five major groups. The cultivars of extremely high petiole group were the same with those of extremely high flower group, those were ‘Dongrihong’, ‘Lianyungang Donghe’, ‘Jinfeng Zhanchi’. The leaf diameter, flower diameter of ‘Lianyungang Donghe’reached a very extremely high level, and also was a long-flowering species with a flower duration up to 118 days. In middle-height petiole group and middle-height petiole group, the flowering duration of “Hongjianlian” and “Xingkong Mudan” were respectively 112 and 123 days, reaching the level of long flowering duration. Ornamental lotus cultivated in deep water, according to the classification of phenotypic traits and quantitative traits, could provide abundant variety selection for wetland landscaping.
