Abstract: This experiment was conducted at Ya'an,Sichuan province from April 28 to Septemb er 28,1998,to search for a significant nitrogen fertilizer treatment on be rmudagrass turf establishment.It indicated that 4g/m2×4 times/month result in the fastest established,best quality bermudagrass turf,followed with 8g/m2×4 times/month and 2g/m2×4 times/month.Through the experiment,it suggested that during bermudagrass turf establishment,each nitrogen application rate shou ld be no less than 2g/m2,and application interval should be less than 3 weeks.

Key words: Nitrogen fertilizer, Tifway bermudagrass, Establishment result speed, Turf quality

摘要: 以三倍体狗牙根为材料,研究施氮量和施氮频率对成坪速度、成坪质量及对杂草竞争力进行综合评价。结果表明,施氮量以4g/m2×4次/月成坪快,质量佳,杂草出现率低。施氮频率以4次/月较好。一次施氮量在3周内以4g/m2建坪速度快,质量高。低施氮频率时则以8g/m2为佳。
