【摘要】 为筛选出适应我国北方气候的狗牙根品种,本试验对美国5个狗牙根品种进行了引种适应性研究,评价指标包括:生育期、密度、色泽、质地、均一性和草屑积累总量等。结果表明:供试狗牙根品种可以在保定地区越冬,但绿期长短差异较大,‘Yukon’绿期最长,达到193 d,‘SR 9554’和‘LaPaloma’绿期最短,仅为145 d。品种‘Yukon’在夏季能形成优美的草坪质量,生长速度适中,而且具有较强的抗病性。更多还原

【Abstract】 In order to select the bermudagrass varieties which adapt to the climate of north China,adaptability of 5 American seeded bermudagrass varieties was studied in Baoding,China.The growth and development period,grass density,color,leaf texture,turf uniformity and the clipping yields were evaluated.The results showed that 5 bermudagrass varieties could live through winter in Baoding,but there was a great difference in the green period.’Yukon’had the longest green period to 193 days,while ’SR 9554’and ’LaPaloma’ both had the shortest green period,only 145 days.’Yukon’could produced excellent turf quality in summer.It had moderate growth rate and strong resistance property to disease compared with other varieties.更多还原
