The results showed that tall fescue traple is the hest , tall fescues melike is the second , red clove redquin is the third , award of kentucky bluegrass the worst and the others in the middle in introduced 9 species , according to soil and water conservation and forage grass 结果表明，在参试的9个品种中，以翠碧高羊茅的综合性状最佳，第二为迈洛克高羊茅，第三为雷得昆红三叶，草地早熟禾的优异和新哥来德最差，其它品种居中。

The results showed that quantity of bacterium and four bacterial physiology groups was positively correlated with quality of illumination ; their quantity showed a reduced tendency with the reducing of the illumination condition , but quantity of fungi was negatively correlated , it was increased gradually with the reducing of the illumination condition ; rhizosphere soil of kentucky bluegrass turned into fungi type from bacterium type ; the rhizosphere effect of various bacterial physiological group of kentucky bluegrass is obvious under different quality of illumination 结果表明，草地早熟禾根际细菌及四类细菌生理群数量与光照条件呈正相关，随着光照条件的减弱，其数量呈降低趋势；根际放线菌数量随光照的减弱呈先下降后上升的趋势；而真菌数量与光照条件呈负相关，随着光照条件的减弱，根际真菌的数量逐渐增加；草地早熟禾根际土壤由“细菌型”向“真菌型”转化；不同光照条件下，根际各微生物类群都表现出明显的根际效应。

The rhizosphere microflora dynamics of bacteria , actinomyces , fungi and four bacterial physiological groups of kentucky bluegrass under different quality of illumination were studied by adopting selective culture medium to explain scientifically response regular of this grass to different illumination condition 摘要研究了草地早熟禾在不同光照条件下其根际与非根际细菌、真菌、放线菌以及氨化细菌、硝化细菌、好气性纤维素分解菌、固氮菌生理类群的区系动态变化，拟从根际土壤微生物数量变化方面来阐述草地早熟禾对不同光照条件的响应规律。

An experiment has been conducted for investigating the rule of water consumption with three species of turfgrasses : kentucky bluegrass ( poa pratensis ) , perennial ryegrass ( lolium perenne ) , and tall fescue ( festuca arundinacea ) ; two kinds of irrigation water resources : tap water and sewage effluent ; and two kinds of irrigation methods : subsurface dripping irrigation and subsurface leaky pipe irrigation 本研究以三种典型的冷季型草坪草草地早熟禾、多年生黑麦草、高羊茅为供试草种，以自来水和经过砂过滤和沉淀处理的城市居民社区的生活污水为灌溉水源，采用地下滴灌和渗灌两种灌水方法，通过田间对比试验，探讨了污水灌溉条件下草坪草的耗水规律。

In a word , there are some achievements as following : 1 ) ecological restoration of the abrupt rock slope in high - cold area should adopt junior planting method . 2 ) the grass seeds for protecting slope in high - cold area should be anti - frost , anti - meager and extensive farming . there are some grass seeds recommended for ecological restoration , for example , kentucky bluegrass , ryegrass , coronilla , festuca arundinacea , sword - bamboo and euonymus fortunei ( 2 )高寒地区生态护坡的草种应选用具有抗寒、抗贫瘠和适宜粗放管理的冷季型草种，推荐使用的川西高寒地区生态护坡植物种属为：草地早熟禾、黑麦草、小冠花、高羊茅的草种组合，剑竹灌木种，以及小叶扶芳藤藤蔓植物种。
