摘　　要：本研究试图探明狗牙根草茎在不同播种深度和施肥方法下对高尔夫草坪备草区建植生长的影响。采用二因素随机区组设计,在高尔夫草坪备草区大田中对不同播种深度(1,2和3cm)和施肥措施(底肥和追肥)进行比较分析。结果表明,生长成坪期间草坪草的盖度、种群密度和株高随着播种深度的增加而增加,但是在成坪后期播深2和3cm对草坪质量的影响差异不显著;追肥比底肥效果好。在狗牙根草茎高尔夫草坪备草区建植生长中,播种深度是首要因素,其次是施肥方法;两因素交互作用显著。结合建植成本和工期,在生产实践中推荐采用播种深度应为2cm,播后1周内追肥,并建议施用速效肥。The influence of fertilizing and planting depth on establishment and growth of Cynodon dactylon（bermudagrass sprigs） for golf course preparation was investigated.A field experiment on golf course preparation was based on a two factor randomized block design with experimental factors of planting depth（1,2 and 3 cm） combined with fertilizing before and after planting.The coverage,density and height of C.dactylon during growth and establishment increased with planting depth but;there was no significant difference between 2 and 3 cm planting depth in the later growing period.There was better establishment with fertilizing after,but not before,planting.Planting depth of C.dactylon was more important than fertilizing,and there was a significant interaction between the two experimental factors.A planting depth of 2 cm and fertilizing with quick releasing fertilizer one week after planting C.dactylon is recommended taking into account the costs and time limit in industrial production.
