摘要
对太原市内芍药的分布及生长特性进行了系统分析。通过对四大园区(迎泽公园、植物园、双塔公园、晋祠公园)芍药资源的调查,发现太原市的芍药资源较为丰富,其中植物园品种最多,为17个,生长状况良好;其次为迎泽公园,15个;晋祠公园和双塔公园较少,均为13个。晋祠公园栽植年限较长,部分品种有病虫害问题,生长状况较为一般;双塔公园的栽培年限较短,尚需进一步观察。在生长特性方面,各个品种的差异较大,株高的平均值为75.84 cm,最大值为104 cm,最小值为53.6 cm;冠幅范围65~170 cm,平均值为100.59 cm;单丛枝条数的平均值为15.93枝,最大值为76枝,最小值为6枝;单株开花数的平均值为16.25朵,最高为63朵,最低为3朵。在观赏性状方面也具有较大变异,芍药花型中重瓣型最为常见(26个品种),粉色系最多(17个品种),其次为红和紫色系品种;花径多为10~13 cm;香气较为浓烈的品种相对较少,多为淡香;大多数雄蕊发生变异或全部瓣化;单朵盛开天数最多的品种为2~3 d。总之,太原市芍药品种表现出较高的多样性和较强的生长适应性,各品种间在生长和观赏性状方面差异较大。研究结果为太原市芍药资源的保护、优化和推广提供了数据支持,并为芍药栽培技术的提升提供了有益的参考。
This study conducted a systematic analysis of the distribution and growth characteristics of Paeonia lactiflora in Taiyuan City.Through the investigation of Paeonia lactiflora resources in the four major parks(Yingze Park,Botanical Garden,Shuangta Park and Jinci Park),it was found that the Paeonia lactiflora resources in Taiyuan City were relatively abundant.Among them,the Botanical Garden had the most varieties,with 17,and their growth conditions were good.Next was Yingze Park,with 15 of them.Jinci Park and Shuangta Park were relatively few,each with 13.The planting years in Jinci Park were relatively long.Some varieties had problems with pests and diseases,and their growth conditions were rather average.The cultivation period in Shuangta Park was relatively short and further observation was still needed.The Paeonia lactiflora varieties in Taiyuan City exhibited high diversity and strong growth adaptability,and there were significant differences among the varieties in terms of growth and ornamental traits.The research results provided data support for the protection,optimization and promotion of Paeonia lactiflora resources in Taiyuan City,and offered useful references for the improvement of Paeonia lactiflora cultivation techniques.
