7种草坪草的根系生长量及分形特征比较研究

Comparative Research on Root Growth Quantity and Fractal Characteristics in 7 kinds of Turf Grasses

以王朝早熟禾、凤凰高羊茅、普通脱壳狗牙根、艾森特黑麦草、三叶草、百脉根、弯叶画眉草为供试材料,研究不同种类草坪草的根系生长能力及分形特征。研究结果表明:凤凰高羊茅、普通脱壳狗牙根、弯叶画眉草的冠部生长茂盛,根系发达,根系生长能力较强。

Taking Poapratensis （L.） ,Dynasty, Festuca arundinacea （Schreb.）, Phoenix, Cynodon dactylon （L.） Pers, Lolium perenne （L.） ,Accent, Trifolium repens Linn., Lotus corniculatus L and Eragrostis curvula S.as materials, the rooting ability and fractal characteristics of different kinds of turf grass were studied. The results showed that Festuca arundinacea （Schreb.） , Phoenix, Cynodon dactylon （L.） Pers, and Eragrostis curvula S.had flourished shoot and developed root, what was more, they had better rooting ability than the other four kinds of turf grasses.
