园林地被植物混植技术应用研究

Application Research on Mixed Planting Technology for Ground Cover Plants in Landscaping

络石、常春藤、铜钱草、薜荔、过路黄都是园林应用价值高的地被植物,单一应用中有观赏期生长季节性的局限性,混合栽植博采众长,是实践验证可行的园林种植形式,但表现效果却千差万别,园林审美质量有待提升。以长效性多样性为目标,对络石、常春藤、铜钱草、薜荔、过路黄混植,观察生长状况,探索不同混合比例不同栽植方式混植地被的园林表现效果。通过选择不同数量比例,进行对比试验,经过4年的持续观察,研究不同混植比例对植被的新梢长度、粗度、叶片大小的影响,结果表明络石:常春藤:铜钱草:薜荔:过路黄进行1:4:4:1:4栽植,生长势覆盖度、色彩丰度、叶片质地效果较好。通过叶片大小色泽和密度观察,栽植方式比较发现栽培坡度为10:2的混植效果较好。

Trachelospermum jasminoides,Ivy(Hedera helix),Ficus pumila,Lysimachia christinae,and Hedera nepalensis are ground cover plants with significant landscaping value.Individually,these plants have lim-itations in terms of seasonal ornamental growth,and monoculture planting has its shortcomings.Mixed planting,which leverages the strengths of different species,is a practical and effective landscaping approach,though the aesthetic outcomes can vary widely.This study aims to achieve long-term diversity by examining the mixed planting of these ground cover plants.Different planting ratios and methods were tested to observe their effects on growth performance.Comparative experiments were conducted using various ratios over a period of four years.The study assessed the effect of different planting ratios on new shoot length,thickness,and leaf size.The results showed that planting in a ratio of T.jasminoides:Ivy:L.Herba:F.pumila:L.christinae=1:4:4:1:4 pro-duced better growth vigor,coverage rate,color richness,and leaf texture.Through observations of leaf size,col-or,and density,it was found that the mixed planting effect was better with a planting slope ratio of 10:2.
