The results showed that the adaption of lolium was higher than poa and festuca 结果表明：黑麦草类的适应性状和坪用性状均优于早熟禾和高羊茅类。
Ryegrass is considered as a good turfgrasses in the winter months for quick coverage but prone to diseases and they cannot grow through the summer 黑麦草种子很快发芽，生长极迅速，为良好之冬日护土用草，但多病害又不越夏。
The somaclonal variation of regeneration plant derived from mature embryo of perennial ryegrass ( lolium perenne l . were analyzed with rapd makers 摘要以多年生黑麦草成熟胚诱导获得的再生植株为材料，利用rapd标记方法对其体细胞变异进行了研究。
The thesis approve research objects have representative character and universality after systematic analysis of zoology adaptability of poa pralensis , red fes cue and target percnnia ryegrass 本文在系统地分析了黑麦草、紫羊茅和早熟禾的生态适应性后，进一步证实了研究对象具有典型性和普遍性。
The releasing capacity , rate and availability of nonexchangeable k in soils with rich illite were much higher than those in others with rich kaolinite or montmorillonite , so that the amounts of nonexchangeable and total k absorbed by ryegrass and dry biomass in the soils were higher than those in others 富含伊利石的土壤非交换性钾的释放量大，速率快，有效性高；黑麦草吸收该土壤的非交换性钾量及总吸钾量高，生物量大。
The averages of release capacity and rate , amounts of nonexchangeable and total k absorbed by ryegrass and dry biomass in kaolinitic and montmorillonitic soils were 46 . 96 、 45 . 50 、 41 . 65 、 43 . 90 and 67 . 52 of those in illitic soils 而富含高岭石或蒙脱石的土壤非交换性钾有效性明显较低；非交换性钾的释放量和速率、黑麦草吸收该土壤的非交换性钾量、总吸钾量及生物量的均值分别仅为富含伊利石土壤的46 . 96 % 、 45 . 50 % 、 41 . 65 % 、 43 . 90 %和67 . 52 % 。
The first system consisted of a bucket filled with a substrate of sand / gravel ( 20cm of depth ) , on the bottom of which was a 80 mesh / inc2 of nylon ( s1 ) ; the second was similar , but was planted with lolium perenne lam ( s2 ) ; the third was planted with a grass plate consisting of 7 layers unwoven fabric planted with l . perenne ( s3 ) 第一个装置底层装20公分高的沙砾，上面放80目尼龙（ s1 ） ；第二个装置底层也放同样动西，但上面放多花黑麦草；第三个装置里面放着底层为7层无纺布上面种着多花黑麦的圆盘。
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。
