‘华南’假俭草的坪用性状评价

Evaluation of turf quality characteristics of Huanan Centipede grass

为研究‘华南’假俭草(Eremochloa ophiuroides‘Huanan’)的坪用性状及推广应用价值,以野生假俭草和美国‘Common’假俭草为对照,用3年时间对‘华南’假俭草的坪用性状(盖度、密度、均一性、颜色、质地)、适应性(成坪天数、绿期、抗病虫性以及越冬越夏率)和草坪综合质量进行了观测和比较评价。结果表明,3种假俭草在广州地区均能正常生长,与野生假俭草和美国假俭草比较,‘华南’假俭草具有质地优、绿期长的明显优势,其叶片宽度为3.24 mm,比野生假俭草的3.95 mm和美国假俭草的4.12 mm分别窄17.97%和21.36%;绿期长达336 d,比野生假俭草和美国假俭草分别长29和32 d;草坪质量综合评价结果为华南>野生>美国。说明‘华南’假俭草可作为一个优良的草坪草在华南地区及气候相似地区推广使用。

To study the turf quality characteristics and popularization value of Huanan centipede grass(Eremochloa ophiuroides‘Huanan’)with wild centipede grass and American Common centipede grass as controls,the turf characteristics(coverage,density,uniformity,color,and texture),adaptability(turf-establishment time,green period,resistance,and overwintering and over-summering rate),and comprehensive quality of the three centipede grasses were observed and evaluated during the 3 experimental years.The results showed that all three centipede grasses grew normally in Guangzhou.Compared with the wild centipede grass and the American Common centipede grass,‘Huanan’centipede grass displayed advantages in terms of texture and green period.The leaf width of Huanan centipede grass was 3.24 mm,which was 17.97%and 21.36%narrower than the 3.95 mm of the wild centipede grass and 4.12 mm of the American Common centipede grass,respectively.The green period was 336 days,which was 29 and 32 days longer than that of the wild centipede grass and American Common centipede grass,respectively.The turf quality was evaluated and ranked as Huanan>Wild>American Common,indicating that Huanan centipede grass could be used as a good turf grass in South China and similar climatic regions.
