优良草坪草相同播种量的比较研究

The comparative study on applying the same sowing rate for fine turfgrass cultivars

在12g／m2的相同播种量下，分析研究不同草坪草种的出苗状况、成坪速度、草坪密度及适应性表现，结果表明：各草坪草10d左右出苗，15d全苗。紫羊茅、硬羊茅和草地早熟禾均能在较短时间内形成低矮致密的草坪。高羊茅、多年生黑麦草和草坪混合种生长前期均表现草坪密度不够，狗芽根出苗差，形成草坪时间长。

Emergance of seedling,speed of lawn establishment,density and adaptability of 19turfgrass species with the same sowing rate of 12 g/m2 were studied. The results showedthat all the species germinated in 10 days and all seedling emerged in 15 days. Red fescue(Festuca rubra ), hard fescue (F. ovina var. duriuscula ) and Kentucky bluegrass (Poapratensis) formed high-density lawnstand in a short term. Tall festuce (Festucaarandinacea),perennial ryegrass (Lolium pere nne) and all the other mixed turf grass speciesdid not show any good densities at the earlier seedling stage, and Bermudagrass usuallyneeded a certain long term for seedling to emerge and to form lawn.
