【摘要】 近年来，随着我国经济建设的迅猛发展，生态园林城市建设对植物造景科学性的要求也在不断地提高，从应用与推广角度对植物造景进行研究的方法日益受到重视。本文结合哈尔滨市草坪植物景观的现状，选择了适宜哈市绿化中分布较广、用量较大，具有代表性的草地早熟禾11个品种(午夜Midnight、纳苏Nassall、伊克利Eclipse、自由女神Liberty、纽斯达Nustar、哥莱德Galade、公园Park、阿林Alene、亨特Huntsville、康尼Conni、光环Nimbus)植物作为研究对象。并对草地早熟禾品种的物候期(返青期、枯黄期、青绿期)主要性状(质地、密度、颜色、耐磨性)、适应性(越冬率、越夏率、抗病性)和建坪后生长速度等方面进行了详细的观测与研究。并通过全美草坪评价体系(NTEP评价体系)对参试草地早熟禾草11个新品种进行了比较全面地质量评估，然后又以环境适应参数(EAP)和坪用参数(TPP)及数理统计分析的方法，对供试草地早熟禾11个新品种进行了量化分析和比较准确的评估，其中对环境适应参数(EAP)评分较高的品种有：午夜、纳苏、伊克利、康尼；在坪用参数两项评分较高的品种有：午夜、纳苏、伊克利、亨特、康尼、光环。在统计分析基础上，通过不同修剪高度(4cm、6cm、8cm)对不同品种的草坪草种进行了标准差和差异系数值的比较，确定了草地早熟禾不同品种的修剪高度。筛选出适宜哈尔滨市气候与生境条件的最佳品种(是康尼、午夜、亨特、纳苏、光环、伊克利)。并分析了其它品种之间的个体差异及与最佳品种之间的不同之处，为哈尔滨市草坪草新品种的应用与草坪植物造景提供了科学依据。同时又对草坪植物在园林中的应用进行了总体分析与讨论，阐述了草坪植物在园林植物造景中的功能与作用，提出了草坪植物科学合理的配置方式，为草坪植物在实际应用中提供科学的理论依据。更多还原

【Abstract】 With the rapid development of our country economy building, the scientific resquest on plant building up landscape continuously has increased during the ecology gardens cities building for recent years. The method of study on the plant building up landscape has alse been thought much from the point of application and spreading. The paper selected eleven varieties grassplot prematurity standing graim with prematurity (Midnight, Nassall, Eclipse, Liberty, Nustar,Galade,Park, Alene, Huntsville, Conni, Nimbus) as research object. We carried out detailed observe and study on mostly properties (texture, density, colour, surgrind) and applicability (live through the winter and the summer.redisease) and growing rate after building up grassplot in the substance season period (regreen period, scorch period, viridity period). And we carried out all-side quality estimate on eleven varieties through NTEP appraise system. Then did amount change and exacter estimation about them with the environment adaption parameter and use of grassplot parameter and number statistic analysis method. Among them, the higher grade varieties for environment adaption parameter are : Midnight, Nassall, Eclipse, Conni., and the higher grade varieties for use of grass parameter are : Midnight, Nassall, Eclipse, Huntsville, Conni, Nimbus. On the base of the statistic analysis, shearing height in different varieties have made certain through different shearing height for different variety grass comparing criterion margin and difference quotieth value. Accordingly best varieties selected in accord with Harbin’s climate and entironment condition are Conni, Midnight, Huntsville,, Nassall, Nimbus, Eclipse . Moreover, we analyzed the individual difference among the other varieties and different scientific basis for application and building up landscape with law grass’s new variety in Harbin City. At the same time, we analyzed and discussed as a whole the application of the lawn plant in the garden. We expatiated the function and effect of the lawn plant in garden plant building up landscape and brought forward scientific and reasonable ordonnance mode. Consequently, theoretics basis reasonable was provided for lawn plant in practice application.更多还原
