摘　　要：以青绿苔草(Carex breviculmis)、一年生黑麦草(Lolium multiflorum)、草地早熟禾(Poa pratensis)为试材,采用温室直播的草皮生产方法,研究了不同播种量(4、8、12 g·m^(-2))的一年生黑麦草、草地早熟禾分别与10 g·m^(-2)的青绿苔草混播,以期确定二者与青绿苔草混播生产草皮的适宜播种量。结果表明:一年生黑麦草播种量由4 g·m^(-2)上升至12 g·m^(-2),混播草皮的成卷时间、盖度、均一度、地下部生物量等指标均显著提升(P<0.05);草地早熟禾播种量在达8 g·m^(-2)后,进一步增加其用量混播草皮的各项指标除青绿苔草分蘖数比重外均无显著变化。综合生产成本考虑,在该研究条件下2种冷季型草与青绿苔草混播适宜播量分别为青绿苔草10 g·m^(-2)+一年生黑麦草12 g·m^(-2);青绿苔草10 g·m^(-2)+草地早熟禾8 g·m^(-2)。Carex breviculmis,Lolium multiflorum and Poa pratensis were used as experimental materials,the effects of different seeding rates(4,8,12 g·m^(-2))of Lolium multiflorum and Poa pratensis mixed with 10 g·m^(-2)of Carex breviculmis were studied by the method of direct seeding in greenhouse,in order to determine the suitable sowing amount of the two mixed with Carex breviculmis to produce turf.The results showed that the sowing rate of Lolium multiflorum increased from4 g·m^(-2)to 12 g·m^(-2),and the indexes such as rolling time,coverage,uniformity and underground biomass of mixed sowing turf were significantly increased(P<0.05).When the sowing rate of Poa pratensis reached 8 g·m^(-2),there was no significant change in the indexes of mixed sowing turf except the proportion of tiller number of Carex breviculmis.Considering the comprehensive production cost,under the experimental conditions,the suitable sowing rates of two coldseason grasses mixed with Carex breviculmis were Carex breviculmis 10 g·m^(-2)+Lolium multiflorum 12 g·m^(-2);Carex breviculmis 10 g·m^(-2)+Poa pratensis 8 g·m^(-2).
