摘　　要：[目的]初步探讨栽培基质、修剪和践踏栽培因素对海滨雀稗草生长特性的影响。[方法]在海南省某高尔夫球场,以粒径为0.5mm的海沙和河沙为栽培基质材料,从海滨雀稗草圃选用当年生健壮茎段扦插进行草坪建植;对球场的高草区、球道区、发球区进行草坪草修剪作业,随机抽样观测该草坪的密度和质地,并以0、5、10、15、20、30、50人次的践踏方式进行践踏处理。[结果]2种栽培基质中,河沙处理使海滨雀稗草的根长为21.52cm,最大分蘖数为17,明显高于海沙处理,说明河沙有利于海滨雀稗草的生长,值得推广;修剪对海滨雀稗草的质地和密度有较大影响,草坪的质地和密度随着修剪高度的变化发生变化;适当的践踏有利于海滨雀稗草最大的生长。[结论]该研究结果可指导海滨雀稗草的生产与管理。[Objective] The study aimed to preliminarily explore the effects of cultivation factors including growing media,pruning and trampling on growth characteristics of seashore Paspalum（Paspalum vaginatum）grass.[Method] On a golf course in Hainan Province,with the sea sand and river sand in the size of 0.5 mm as the growing media materials,the current-year healthy stem sections selected from the nursery of seashore Paspalum grass were made for the cottage to establish the lawn.The lawn grass in the high grass zone,fairway zone and service zone of the golf course were pruned and the density and texture of the lawn were observed through the random sampling.The trampling treatments on the lawn were made with the modes of trampling resp.by 0,5,10,15,20,30 and 50 people per time.[Result] In 2 growing media,the river sand treatment made the maximum root lengthen of seashore Paspalum grass to be 21.52 cm and the maximum tillering number to be 17,which were obviously higher than the sea sand treatment,showing that the river sand treatment was propitious to the growth of seashore Paspalum grass and it was worth to be popularized.The pruning had the great influence on the quality and density of Seashore paspalum grass and the quality and density of the lawn varied with the height change of the pruning.The suitable trampling was advantageous to the growth of Seashore paspalum grass.[Conclusion] The study could provide a guide for the cultivation and management of seashore Paspalum grass.
