| 摘 要： | 在不同品种搭配和修剪强度为7、10、13d／次和不同留茬高度5、8、11cm，对青海草地早熟禾密度、质地、颜色、均一性等多项指标进行观测，并运用灰色关联度进行分析，结果表明：青海草地早熟禾幼苗抗寒性好，且出苗率为65％以上；高频度的修剪更有利于其良好生长，8cm的留茬高度下，青海草地早熟禾各项指标表现最佳；青海草地早熟禾与青海中华羊茅的混播，在两样地中综合表现尤为突出。

| Abstract: | The density,colour,texture,uiformity of Poa pratensis cv.Qinghai turf under different sowing formulas and mowing intensity(mowing intervals of 7,10 and 13 days;stubbles of 5,8 and 11 cm) were measured and analyzed with gray association method.The result indicated that the seeding rate was over 65% and the cold tolerance of seedling was strong.The best stubble height was 8 cm.The performance of mixed turf with Poa pratensis cv.Qinghai and Festuca sinensiscv.Qinghai was promising. |
