摘要
用正交法进行田间试验,研究了施肥、修剪、和草种差异对冷季型草坪草根系深度影响。结果表明:在乌鲁木齐这样的干旱区城市,根系深,抗旱力强的草种适于本地生长。草种和修剪频度差异对草坪丰富根系深度影响显著,草种对最大根系深度影响差异极显著。在草坪管理中,选用深根性草种,修剪频度两周1次,有利于草坪丰富根系深度和最大根系深度增加,提高草坪生长质量,提高抗旱力。冷季型草坪草种(品种)对于草坪最大根系深度影响差异显著。以最大根系深度比较,紫羊茅根系最浅,耐旱能力差;高羊茅根系最深,耐旱好;早熟禾草和黑麦草的耐旱能力居中。
Effects of fertilize, mowing and species on root system in Cool-Season Turf grasses were carried out in Urumqi. And difference between species and management model was compared. Management model, such as fertilize and mowing, on turf grasses which suit to local was suggested as well.
