6种开花地被植物坪用价值的比较研究

Assessment on Turf Quality of 6 Varieties of Flowering Cover Plants

针对目前地被植物研究中系统的定量研究和坪用特性研究较少的状况,选用紫花地丁、紫花苜蓿、草莓红三叶草、白三叶草、地被石竹和常夏石竹六种开花地被植物进行坪用价值的比较试验。观测指标主要包括叶片密度、叶片质地、叶色、均匀性、开花期、生长高度、绿期和综合评分等。试验在山西农业大学林业实验站的大田进行。采用改良后的美国国家草坪评比体系NTEP(9分法)作为评比标准。实验结果表明,6种实验材料都具有一定的坪用价值,但地被石竹和长夏石竹的表现较好。尤其是地被石竹的综合评价结果远远高于另外五种地被植物。可作为北方地区的草坪替代品种大面积推广。经改良后的草坪质量评估方法原则上可用于低矮地被植物坪用价值的评价。但在高度和开花特性等指标的设置上应作进一步实验改进。

Based on the current research situation that is less on the quantitative research and the lawn characteristic research, 6 varieties of flowering cover plants, Viola Philippica, Medicago sativa, fragiferum, L, Trifolium pretense Dianthus chinensis and Dianthus plumarius were used to turf characteristic comparing test. The observation target includes leaf density, leaf texture, leaf color, uniformity, flowering time, high, green time and all-round appraise. The test was carried out in the experiment station in Shanxi Agricultural University and the improved National Turfgrass Evaluation Program （NTEP） was used. The result showed that 6 varieties plants have lawn value and Dianthus chinensis and Dianthus plumarius are better. Especially all-round assessment result of Dianthus chinensis is the highest and an advice is given that Dianthus chinensis will be popularized widely. Generally, the turfgrass quality evaluation way by improved is fit for lawn characteristic evaluation of low-growing cover plants.
