摘要
７种草坪植物地下器官，在０～５ｃｍ深的土壤层中的根系，占全部根系年均长度的６２．９％．根系最长的是紫羊茅．为１０４１３０ｍ／ｍ２．其中５种草坪草的根状茎，占全部根拔茎平均长度的８０．６％，而根状茎最长的是草地早熟禾，为１６２６ｍ／ｍ２．根系长度的８９％与根状茎长度的９３％左右，都集中在１０ｃｍ深的土壤层中．
In terms of percentage, root length of seven species in the turfgrass made up 62.9 per cent of the total root length of all species in the turfgrass in surface lager of 0￣ 5 cm. Root length of the Red Fescue was longest among these turfgrasses, and amounted to 104 130 m/m2. In addtion, rhizome length of five species or the turfgrass accounted for 80.6 per cent of the total rhizome length of all species in the turfgrass,and the rhizome length of the Kentuky Bluegrass was longest among these turfgrasses, and amounted to 1 626 m/m2. Root system of 89.0 per cent and rhizome of 93.0 percent (measured in length) were distributed in soil horizon of 0￣10 cm.
