摘要
地被植物在神东矿区绿化过程中起到重要作用。目前选取使用面积较大的草本地被植物有蜀葵、三七景天、草地早熟禾、紫花苜蓿、金娃娃萱草、马莲,木本地被植物有沙地柏、紫丁香、红瑞木、紫穗槐、侧柏为研究对象,对其盖度、观赏性、经济性进行分析比较。结果表明5种木本地被植物紫丁香、红瑞木的盖度最高,紫穗槐盖度最低,冬季(除沙地柏、侧柏常绿灌木外,其它地被处于枯黄期)侧柏盖度最高,紫穗槐盖度最低;6种草本地被植物生长旺盛期与枯黄期草地早熟禾盖度最高,蜀葵盖度最低;5种地被植物紫丁香观赏性评价最高,6种草本类植物金娃娃萱草观赏性评价最高;5种木本地被植物紫穗槐栽植费、养护费用最低,6种草本地被植物紫花苜蓿栽植费、养护费最低。根据盖度、观赏性、经济性指标的分析比较结果,可根据需要选择适合神东矿区栽植的地被植物。
Ground cover plants play an important role in the greening process of Shendong mining area.At present,the widely used herbaceous ground cover plants are hollyhock,Aizoon stonecrop herb,Kentucky bluegrass,alfalfa,Hemerocallis aurea and Marigold,and the woody ground cover plants are Sabina vulgaris,lilac,Cornus alba,false indigo and Platycladus orientalis.Based on the analysis of the coverage,ornamental and economic of ground cover plants,the results showed that the coverage of lilac and Cornus alba was the highest,that of false indigo was the lowest,that of Platycladus orientalis was the highest and that of false indigo was the lowest in winter,that of Kentucky bluegrass was the highest in the vigorous growth period and the withered yellow period,that of hollyhock was the lowest,and the ornamental value of lilac and Hemerocallis aurea was the highest,and the planting and maintenance cost of false indigo and alfalfa were the lowest.According to the index of coverage,ornamental and economic,the suitable ground cover plants for Shendong mining area can be selected.
