地椒引种试验与园林应用的初步研究

Research on the Introduction and Landscape Application of Wild Thyme (Thymus serpyllum L. var. asiaticus) Preliminarily

对内蒙古自治区武川段大青山分布的野生地椒(Thymus serpyllum L.var.asiaticus)进行引种试验,对其引种成活率、引种后的生长特性、成坪特性等进行研究。结果表明:地椒经引种后,缓苗期15天,成活率为92.3%。在引种后,地椒的株高、株展、茎长、分枝、叶片数都表现为"慢—快—慢"的生长趋势,符合生长大周期规律。在引种后的盖度变化则表现为前期快速增加,后期缓慢,到定植70天后,盖度达到95.6%,到85天时,达到了100%。成坪速率为每天1.50%。生长特性和成坪速率分析表明,地椒适合作为园林绿化地被植物应用。

The introduction test of wild Thymus serpyllum L. var. asiaticus grown in Daqingshan Mountain of the Wuehuan County in the Inner Mongolia autonomous region was carried out. It was researched on that were the living rate, growing characteristics and the landscape characteristics after introduction. The results showed that the recovering stage was 15 days and the living rate was 92.3% after the introduction of the wild plant named Thymus serpyllum L. var. asiaticus. The growing characteristics such as plant height, plant breath, shoot length, the number of branches and leaves were researched on. They all had the same regular that the growing rate were quickly in the earlier stage, slowly in the middle stage and quickly in the later stage, which fit to the grand period of growth. The coverage rate was quickly in the earlier stage and slowly in the later stage. It was 95.6% when they have been transplanted for 70 days, and it was 100% when they have been transplanted for 85 days. The landscape rate was 1.50% everyday. All the results showed that the wild plant named Thymus serpyllum L. var. asiatieus was suitable for the landscape application as the ~round cover nl^nt
