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

Taking Poa pratensis (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.
