摘要： 利用综合评定分析的方法评价匍匐型天蓝苜蓿（Medicago minima L.）、小苜蓿（Medicago lupulina L.）与禾本科草坪草（草地早熟禾（Poa pratensis L.）、多年生黑麦草（Lolium perenne L.））混播后绿地草坪的品质；同时研究它们的植株生长和根系分布，探讨豆禾混播对禾本科草坪景观的影响。结果表明：天蓝苜蓿、小苜蓿与禾本科草坪草混播可以促进禾本科草坪草生长，豆禾混播草坪性能优于禾禾混播，其中天蓝苜蓿与这两种禾本科草坪草混播效果佳，可形成致密、颜色均一的绿地草坪；在叶色上，天蓝苜蓿适合与叶片颜色较深的禾本科草坪草混播，而小苜蓿则适合与叶片颜色较浅的禾本科草坪草混播；混播草坪中豆科根系分布较深，禾本科根系分布较浅，豆禾混播可利用不同土层的营养物质；两种豆科植物较适宜的播量均为2 g·m-2，与禾本科草坪草混播最佳的播种时间为秋季。综合分析认为，天蓝苜蓿、小苜蓿与禾本科草坪草混播可以建造优质、美观的绿地草坪。

Abstract: This study was conducted to evaluate the mixed sowing effect of leguminous Medicago minima and Medicago lupulina and turf grass included kentucky bluegrass (Poa pratensis L.) and perennial ryegrass (Lolium perenne L.),respectively,by comprehensive evaluation analysis. At the same time,both the length of the root and their distribution in the soil were measured,and the nodule was also necropsied. The results showed that:Medicago minima and Medicago lupulina was mixed individually with turf grass had higher density and coverage than pure grass seeding. The best group was Medicago lupulina and turf grass. Regarding to the leaf color,Medicago minima was suitable to mix with turfgrass of light color leaves. The root of legume plants and turf grass were distributed in different depth,which reduced the competition for resources and could make full use of soil nutrients. This study suggested that autumn was the best sowing time for the two leguminous plants,and the optimal seeding rate of the two kinds of leguminous plants was 2 g·m-2. In conclusion,we suggested that Medicago minima,Medicago lupulina mixed turfgrass could develop beautiful and high quality lawn.
