摘 要:对6个多年生黑麦草Lolium perenne品种在南京地区进行田间建坪试验,分别对出苗速度、草坪密度、叶片宽度、再生速度、SPAD值、死枯率和表观质量进行观测。结果表明,6个品种在春秋冬季均表现出良好的适应性,出苗迅速,成坪快,草坪质量较高。随着夏季高温季节来临,各供试品种的密度减小、叶宽变窄、再生速度减慢、表观质量下降,其中火炬、富豪5号叶片细腻,成坪快,在春秋冬季综合质量较高而进入夏季后枯死较早且死亡时间一致,适宜于南京及同类气候地区草坪的交播。The turf characters of 6 varieties of perennial ryegrass, including the speed of seedling emergence, tiller density, texture and turfgrass quality was studied to evaluate their suitability under field conditions in Nanjing. The results showed that 6 varieties performed well in seedling emergence and turf establishment and better adaptability and turf performance during the spring and autumn. Tiller density, turf quality, texture and regeneration speed of the tested varieties declined under the stress of heat in summer, in which, the turf characters of Ignite and Regal 5 were better than other varieties and could be used for overseeding in Nanjing and other regions with the same climate.
