<正>对黑麦草、高羊茅、早熟禾３个冷季型草坪草的４０个品种进行年周期综合评价（耐旱性、耐寒性、耐热性、叶色、绿期、抗病性），表现较好的高羊茅品种是：凌志、节水草、凤凰、小野马、盆景，维加斯；黑麦草是：尤文图斯、曼哈顿；早熟禾品种是：康派、康尼、克利。

Field studies were conducted over a year-cycle with 40 cool-season turfgrass Cultivars. Integrated grade index comprises drought-resistance, chill-resistance, heat-resistance, leaf color, green duration, and disease-resistance. As a result, data demonstrate that the scores of Ballexas, Phoenix, Water saver, Minimustang, Mustang, Bonsai, Vegas are higher than the others cultivars of tall fescue (Festuca arundi nacea). The scores of Juventus, Manhattan are the highest in the perennial ryegrass cultivars (Lolium perenne L. ). The scores of compact, conni, and kerley are higher in the Kentucky bluegrass (Poapratensis L. ) cultivars.
