摘 要:在北京地区对5个冷季型和1个暖季型草种共112个品种的草坪质量变化及影响因素进行了研究.结果表明,在5个冷季型草种中,多年生黑麦草和剪股颍建植速度最快,草地早熟禾建植速度最慢.暖季型草种狗牙根是6个参试草种中建植速度最慢的一个.暖季型和冷季型草种的草坪质量在季节上存在明显差异.暖季型草坪草在最热的7、8月份表现最佳,而冷季型草坪草在春季和秋季表现良好.气候的季节变程和草种是影响草坪质量最重要的因素,而品种之间的变差较小,其贡献大小和重复间的贡献相当.Lawn quality of 112 cultivars including five cool-season species and one warm-season species turfgrasses were evaluated and its influence factors were analyzed in Beijing area. The results showed that Lolium perenne and Agrostis had the fastest establishing speed, and Poa pratensis the slowest among five cool-season species. Warm-season common Cynodon dactylon showed the slowest establishing speed in six test species. Lawn quality of warm-season and cool-season species had obvious seasonal difference. Warm-season turfgrasses had the highest quality in the hottest July and August, however, cool-season turfgrasses behaved well at spring and autumn. Seasonal change and species are two important factors affecting lawn quality, but variance of different cultivars was small, equivalent to that of different replications.
