摘　　要：[目的]研究不同保水剂对土壤含水量与暖地型草坪草种子萌发的影响。[方法]通过盆栽育苗法,研究不同用量保水剂对2种暖地型草坪草出苗的影响。[结果]经保水剂处理后,狗牙根和红三叶草种发芽率明显提高,分别达17.78%和82.22%,幼苗生长加快;干旱条件下适量的保水剂可以提高土壤的含水量,对草坪草种子出苗及生长具有一定促进作用。[结论]该研究结果为保水剂的园林应用提供依据。[Objective] The aim was to study the effect of different water retaining agents on soil water content and several warm-season turf grasses seed germination.[Method] Through cultivating two warm-season turf grasses in basin,the effects of different water retaining agents on seed germination were studied.[Result] The seed germination rate of Cynodon dactylo and Trifolium pretense improved obviously,were 17.78% and 82.22% respectively,and the growth of seedlings was faster.On drought conditions,using appropriate concentration water retaining agent could improve the soil water content,and turf grass seed germination and growth were accelerated.[Conclusion] This result provides some reference for landscape application of water retaining agent.
