8种野生早熟禾种质材料坪用特性和草坪质量评价研究

摘要

Turf characteristics and quality of eight varieties of wild Poa were evaluated in field experiment.The results showed that the best performance of uniformity,coverage,density,texture,color and green stage was Poa anqustifolia,P.micrandra,P.poophaqorum,P.declinata,P.crymophil and P.pratensis respectively.Considered the six indexes,the order from superior to inferior was as follows： Poa anqustifoliaP.pratensisP.sphodylodesGong yuanP.micrandra P.crymophilaP.poophaqorumP.declinataP.dolichachyra.%通过田间试验,对8种野生早熟禾种质的坪用特性和草坪质量进行了评价研究。结果表明：硬质早熟禾均一性最好,草地早熟禾盖度最高,冷地早熟禾密度最大,波伐早熟禾质地最优,细叶早熟禾色泽最好,硬质早熟禾、垂枝早熟禾和对照草地早熟禾公园绿期最长。综合6项评价指标,8种野生早熟禾草坪质量优劣顺序为：硬质早熟禾〉草地早熟禾〉细叶早熟禾〉公园〉小药早熟禾〉冷地早熟禾〉波伐早熟禾〉垂枝早熟禾〉长稃早熟禾。
