10种地被植物的耐阴性与园林适应性比较

运用综合指标对10种地被植物耐阴性进行评价,依据耐阴性强弱分为3组:1)强耐阴植物:无柄卫矛、疏花仙茅、峨眉蜘蛛抱蛋;2)半耐阴植物:犁头草、蜂斗菜、散斑假万寿竹、黑老虎;3)稍耐阴植物:莓叶委陵菜、紫金牛、铁箍散。根据试验结果,应将犁头草、蜂斗菜、散斑假万寿竹、黑老虎配置于庭院绿地、宅间绿地、公园绿地和林下绿地;莓叶委陵菜、紫金牛、铁箍散配置于道路隔离带、周围有建筑物遮挡的宅间绿地或有适量上层植物覆盖的疏林绿地应用;无柄卫矛、疏花仙茅、峨眉蜘蛛抱蛋配置于阔叶林下、高架桥下、室内或浓密型棚架下等背阴处栽植。

Comparative Studies on Shade Tolerance and Adaptability to Garden-environment Planting of 10 Ground Cover Plants

Shade tolerances and adaptabilities to garden-environment planting of 10 native ground covers were evaluated by comprehensive indices.The covers were divided into 3 groups based on their shade tolerance: 1) Strong shade-resistance group: Euonymus subsessilis,Curculigo gracilis and Aspidistra caespitosa.2) Moderate shade tolerance group: Viola inconspicua,Petasites japonicus,Disporopsis aspera and Kadsura coccinea.3) Weak shade tolerance group: Potentilla fragarioides,Ardisia japonicae and Schisandra propinqua var.sinensis.Based on the results,it was suggested that Viola inconspicua,Petasites japonicus,Disporopsis aspera and Kadsura coccinea should be planted at courtyard green land,home site greenbelt,park green space and underside of forest;Potentilla fragarioides,Ardisia japonicae and Schisandra propinqua var.sinensis however,should be planted at isolation belt,home site greenbelt with building shielding,or open forest greenland;Euonymus subsessilis,Curculigo gracilis and Aspidistra caespitosa should be planted under broad leaved forests,elevated urban railway and north side of thickening arbor.
