| 摘 要： | 在不同的刈割强度下(不同刈割频度7、10、13 d/次和不同留茬高度5、8、11 cm)，对青海草地早熟禾Poa pratensis出苗率、草坪密度、色泽、质地、均一性、再生速度等多项指标进行观测，结果表明：青海草地早熟禾有着较高的出苗率（65%以上），且幼苗抗寒性好；8 cm的留茬高度下，青海草地早熟禾各项指标表现最佳，而7 d/次的刈割频度下再生速度达到极显著水平(P<0.01)；新建植的青海草地早熟禾其再生速度显著高于5龄青海草地早熟禾（P<0.05）。

| Abstract: | The seeding rate,density,colour,texture,uniformity,regeneration speed of Poa pratensis cv.Qinghai at different mow intensity(different mow intervals,7,10 and 13 days;different stubbles,5,8 and 11 cm) were measured.The result indicated that the seeding rate was high(over 65%) and the cold tolerance of young seedling was strong.It performed the best at 8 cm of stubble and 7 days of mow interval.The regeneration speed of newly established turf was significantly higher than that of 5 year-old turf. |
