摘　　要：草坪混播具有广泛的遗传特性,可以在长江流域实现草坪四季常绿。本研究以矮生百慕大、多年生黑麦草为试材,设计4种混播比例组合,分析其草坪质量和适应性,采用NTEP体系进行综合评价。结果表明:70%矮生百慕大+30%多年生黑麦草混播处理的密度为4.4根·cm-2,叶片宽度2.3 mm,地上部生物量0.021 g·cm-2,叶绿素含量0.431 mg·g-1,其综合评分最高,为7.8分。矮生百慕大和多年生黑麦草混播组合可在长江流域实现草坪常绿,其适应性较好,为长江流域常绿草坪混播技术的应用提供技术参考。Because of the wide range of genetic characteristics of mixed sowing,turfgrass can be evergreen all the year round in the Yangtze River Basin.Four mixed sowing ratio combinations of bermuda and perennial ryegrass were designed to analyze turf quality and adaptability,and the NTEP system was used for comprehensive evaluation.The results showed that the density,leaf width,above ground biomass and chlorophyll content of 70%bermuda+30%perennial ryegrass were 4.4 root/cm-2,2.3 mm,0.021 g·cm2 and 0.431 mg·g-1,respectively.With the highest comprehensive score of 7.8.Bermuda and perennial ryegrass mixed sowing combination can achieve evergreen lawn in the Yangtze River Basin,and its adaptability is also good,which provides technical reference for the application of evergreen lawn mixed sowing technology in the Yangtze River Basin.
