花境季节性动态变化研究

Study on Seasonal Dynamic Change of Flower Border

以济南市居住区花境为研究对象,通过实地调研法和物候观测法记录场地内24种植物的花期、株高,并用NCS A-6 1950便携式色卡比对植物色彩。从时间纵横结合、层次结构和色彩动态特征多角度探讨了济南居住区花境的季相特征。结果表明:(1)花期主要集中在春季,排名前三的优势种为藿香蓟、金鱼草、蓝花鼠尾草。(2)植物涵盖5个花色色系,14个色相,28个NCS标准色,紫色系、白色系、黄色系是花境色彩的主要组成部分。(3)春季植物平均生长速率最快,6月份,植物株高与花境景观协调度最低,生长速率快的植物对花境的影响大于生长速率慢的植物。根据研究结果可从24种植物中筛选出盛花期长、花期持续时间久、植株长势优雅的花境选材,为济南以及华东地区花境植物选择提供参考。

Taking the fl ower border of the residential area of Jinan City as the research object,the fl owering time and plant height of 24 plants were recorded by fi eld investigation and phenological observation,and the color of plants was compared with NCS A-61950 por-table color card.The seasonal characteristics of the fl ower border in Jinan residential area were discussed from the perspectives of time vertical and horizontal combination,hierarchical structure and color dynamic characteristics.The results showed that:(1)the fl owering period was mainly concentrated in spring,and the top three dominant species were Ageratum conyzoides,Antirrhinum majus and Salvia farinacea.(2)Plants cover 5 color schemes,14 hues,28 NCS standard colors,purple,white,yellow are the main components of fl ower color.(3)The average plant growth rate was the highest in spring,and the coordination between plant height and fl ower border landscape was the lowest in June.The relationship between different plant growth rates and fl ower border land-scape was as follows:fast growth rate>slow growth rate.According to the results of the study,the 24 plants with long fl owering period,long fl owering duration and elegant plant growth can be selected,which can provide a reference for the selection of fl ower border plants in Jinan and East China.
