12种亚热型常用草坪草品种特性与成坪性比较研究

By comparison of variety and character of becoming lawn of 3y, morphological, biological and ecological character of 12 different turf grass of 8 strain which was ordinarily used in area of sub-tropic were studied by the systematic research indoor and outdoor, physiological resistance and turf performance of grass were studied too. We estimated adaptability, quality, turf-grass performance by parameter of environment adaptability, parameter of turf performance and quality estimated standard in this paper. The result showed: Varieties of Festuca arundinacea L., Poa pratensis L. were most adapted to established in Nanjing area, Lolium perenne L. was more adapted to the area, phase of green of the three grass were long which showed greener than the others, turf of performance were well, heat resistance of Poa pratensis L. was well, Agrostis stolonifera L.was thick green, well turf performance, high cold resistance and drought resistance, but it cannot resist high heat and became scorch in hot summer. Resistance of plant disease and insect pests and heat resistance of Cynodon Dactylon L. were well but ratio of live through the winter was low, phase of green was short and applicability was worse, the turf performance of Trifolium repens and Cynodon dactylon were lower and not adapted to Nanjing area.
