不同类型人造草坪对混合草坪建植质量的影响

The influence of different types of artificial turf on the quality of hybrid turf

不同类型的人造草坪具有不同的草丝密度和底布空隙,对草坪草生长影响很大,是混合草坪建植成败的关键。本研究选用两种规格的常规型人造草坪和4种规格的编织型人造草坪,在人造草坪上采用直播狗牙根(Cynodon dactylon)种子的方式建植混合草坪,以狗牙根草坪为对照,对不同类型混合草坪建植后的坪用性状及其质量进行比较与综合评价。结果表明,经密31.49丝·cm^(−1)、纬密157.48丝·cm^(−1)、草丝密度为1.71根·cm^(−2)的人造草构建的混合草坪,成坪后狗牙根密度为2.54枝·cm^(−2),盖度为88.57%,生物量为9.97 g·盆−1,均一性分值为6.44分,加权均分为8.44分,均高于其他类型的人造草坪。综合评价结果,该规格的编织型人造草坪较适合建植混合草坪。

Different types of artificial turf are characterized by differing fiber densities and gaps in the base fabric,which have a considerable influence on turf growth and are key factors contributing to the successful establishment of hybrid turf.In this study,two types of conventional synthetic turf and four types of woven synthetic turf were seeded with common bermudagrass to establish different hybrid turfs.Following the establishment of hybrid turf,we conducted a comprehensive evaluation of the characteristics and quality of different types of turf compared with the common bermudagrass turf,The results revealed that after the complete establishment of hybrid turf,the density of bermudagrass in the woven synthetic turf,with a longitude density of 31.49 yarns·cm^(−1) and weft density of 157.48 yarns·cm^(−1),and artificial turf density of 1.71 fiber·cm^(−2) and 2.54 shoot·cm^(−2),coverage of 88.57%,biomass of 9.97 g·pot−1,uniformity of 6.44 points,and weighted mean of 8.44 points,were all higher than those of the other types of synthetic turf.On the basis of our comprehensive evaluation,this type of woven synthetic turf was accordingly identified as the most suitable for the fabrication of natural-synthetic hybrid turf.
