摘 要:为了丰富城市的园林景观,营建四季常绿、鲜花怒放的缀花草坪,设计了“马蹄金+猫爪草+夏天无+剪刀股”“马蹄金+老鸦瓣+蒲公英”“马蹄金+紫花地丁+夏枯草”等10个组合。并对马蹄金缀花草坪的建植管理技术进行了探讨,提出了从选址、除草、整坪、播种到养护管理的一系列技术方案,应用液压喷播机播种、整坪前灭生性除草剂除草、生长期选择性除草剂除草、合理施肥、适时修剪间苗、针对性开展病虫害防治等关键技术,以建植马蹄金缀花草坪并保持其景观的稳定性。

Abstract: In order to enrich the landscape of the city and construct the lawn with flowers blooming all the year round, 10 combinations were designed, such as “Dichondra repens+Ranunculus ternatus+Corydalis decumbens+Ixeris japonica”, “Dichondra repens+Amana edulis+Taraxacum mongolicum”, “Dichondra repens+Viola pHilippica+Prunella vulgaris”. The paper also discussed the establishment and management technology of Dichondra repens turfgrass, and put forward a series of technical schemes from site selection, weeding, site preparation, sowing to maintenance and management, such as the application of hydraulic sprayer sowing, weeding before site preparation, selective weeding during growth period, rational fertilization, timely pruning and thinning, targeted pest control and other key technologies, to build a beautiful lawn and maintain the stability of it.

馬蹄金(Dichondra repens)是旋花科的一种多年生匍匐小草本,有细长的茎,茎节上生根。叶肾形至圆形,形似马蹄,花淡黄色,极小,花冠直径仅4mm左右,藏于叶腋,很不起眼。马蹄金有清热利尿、祛风止痛等功效,是一味应用较广的中草药。由于其适应性强,繁殖速度快,常集群成片生长,低矮整齐,又被开发为草坪草。马蹄金是有喜阳、耐阴、耐湿、耐高温、耐瘠薄、抗性强等优点[1],能在我国大部分地区生长,但最适宜在温暖湿润的亚热带地区种植,可保持四季常绿、生长整齐。
马蹄金虽然是一种优良的草坪草,但单独种植时景观单调,四季如一,缺少变化,如果在其上点缀一些低矮艳丽的小野花,则能营造出绿草如茵、鲜花怒放的美丽景观,让人仿佛来到了草原花海,眼前为之一亮。马蹄金的叶形不像禾本科植物那样狭长,属于阔叶植物,与叶形类似的小野花组合起来十分协调,是一种优秀的缀花草坪基底草。……
