Abstract: The experiment was designed as scale of irrigation times for study of the effect of irrigation amount and irrigation time on seed productivity and grown characteristics and seed yield and seed qualityof tall fescue. The result showed that the effect was notable. Seed yield and seed quality and economic benefit increasing when irrigation times increasing. So it was reasonable that the irrigation times were three of four and irrigation amount were 3000～4000m3/ha in Lanzhou district.

Key words: Irrigation, Turf tall fescue, Seed production

摘要： 灌水量和灌水时间显著影响苇状羊茅的结实特性和生长特性,随着灌水次数的增多,种子产量呈增加趋势,种子质量和经济效益也呈增加趋势,因而,在兰州地区适宜于苇状羊茅种子生产的灌水次数为3～4次,灌水量为3000～4000m3/hm2。
