| 摘 要： | 为了减少北京地区草坪草灌水量、提高降水量的利用率，该文研究了充分利用降雨条件下的典型冷季型草坪草灌水量。根据典型冷季型草坪草（早熟禾、高羊茅）2003年的田间试验资料对灌溉制度模拟模型（ISAREG模型）进行了率定，然后用2004年的田间试验资料对ISAREG模型进行了验证，最后应用此模型对所研究的两种冷季型草坪草在干旱年、平水年和丰水年及不同养护条件下的灌水量进行了模拟研究。研究结果表明：生长季节内早熟禾、高羊茅的作物系数在0.5～1.0之间；在特级养护条件下，早熟禾和高羊茅所需灌水量分别为432～682 mm/a、462～752 mm/a；在一级养护条件下，早熟禾和高羊茅所需灌水量分别为252～432 mm/a、312～492 mm/a。研究结果可为北京地区冷季型草坪草的灌溉管理提供科学依据。 |

| Abstract: | In order to reduce the irrigation requirements of turfgrass species and increase the utilization ratio of precipatiation in Beijing,the study focuses on the irrigation requirements of typical cool season turfgrass species under full use of precipatiation.The datasets of two cool season turfgrass species,i.e.,Kentucky bluegrass and Tall fescue collected in 2003 were used to calibrate the irrigation scheduling simulation model(ISRAEG),and then the datasets of 2004 were used to validate the ISRAEG model.Finall... |
| Keywords: | cool season turfgrass crop coefficient irrigation requirement soil moisture simulation |
