摘要
对湖北江汉平原引种的24个冷地型草坪草品种,包括高羊茅Festuca arundinacea8个品种,草地早熟禾Poa pratensis12个品种,多年生黑麦草Lolium perenne4个品种的密度、均匀度、生长速度等坪用性状进行系统测定,同时运用灰色关联理论中的关联度分析方法对各品种进行了综合评判,筛选出综合坪用性状表现优良的草坪草品种有:高羊茅品种“凌志”和“猎狗5号”,草地早熟禾品种“超级伊克利”、“自由2号”、“百老汇”和“解放者”。
A study on lawning characteristics, such as density, uniformity, growth speed and so on, of twenty fourcool-season turfgrass varieties was carried out systemically in Jianghan plain of Hubei province. It included eight tall fescue varieties, twelve Kentucky bluegrass varieties and four perennial ryegrass varieties. Several merit turfgrass varieties were screened out through grey relativity analysis of the varieties＇ characteristics, which were ＂Barlexas＂ and ＂Houndog V＂ of tall fesc.ue and ＂Total eclipse＂,＂Freedom .Ⅱ ＂,＂Broadway＂ and ＂Liberator＂ of Kentucky bluegrass.
