摘要
选取草地早熟禾Poa pratensis、多年生黑麦草Lolium perenne、匍匐紫羊茅Festuca rubra3种草坪草,利用植生纸进行草坪快速建植技术的探索,将自制植生纸与无纺布植生带及纱布植生带进行比较,用覆土厚度为0,0.5,1 cm,施N肥0,6,12,24 g/m2的处理对幼苗生长和出苗率进行试验。结果表明:1)植生纸及纱布植生带与无纺布植生带间无显著差异(P>0.05),可利用植生纸及纱布植生带代替无纺布植生带;2)覆土厚度对出苗率有极显著影响(P<0.01),以0.5 cm出苗率最高,0 cm处理次之,1 cm最低;3)随施肥水平的增加,出苗率极显著降低(P<0.01),以0 g/m2最高,24 g/m2最低。
Bluegrass, perennial ryegrass and red lescue were used to explore rapid turf estaolishing techniques on self-made plant growth band （PGB）, gauze cloth PGB and plain PGB, respectively.Three treatments of cover depth （0, 0. 5 and 1 cm） and 4 treatments of nitrogen fertilizer rate （0, 6,12, 24 g/m^2 ） turned out that there was no significant difference among PGBs （P〉0. 05）, 0. 5 cm cover depth gave the highest seedling emergence followed by 0 cm and then 1 cm. The emergence reducedsignificantly with the increasing nitrogen rate （P〈0.01）, the highest emergence obtained at 0 g/m^2nitrogen, with the lowest at 24 g/m^2 .
