Progress and prospect of the lolium - festuca complex 羊茅黑麦草种群研究进展及前景展望
Study on agrobacterium - mediated gus transformation for lolium perenne l 基因对多年生黑麦草转化的研究
Diagnostic criteria and principles of management for food poisoning of lolium temulentum 毒麦食物中毒诊断标准及处理原则
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。
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。
Percent nitrate nitrogen , ammonium nitrogen and total phosphor was not a significantly variable at the different depths . 2 ) vegetation type results in significant difference in nitrate removal . lolium perenne l is most effective on reducing nitrate nitrogen concentration , accounting to 90 % . for total phosphor , natural vegetation is most effective , reaching 61 . 01 % 2 )不同植被缓冲带对铵氮、总磷、硝氮、总氮的去除效果不同,牧杰对氮盐的去除效果最强,特别是对硝氮的吸收达到90 ,对总磷吸收能力在总体上弱于氮元素的吸收能力,在自然植被处达到最高,为61 . 01 。
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。
Through cultivating five cold - season turfgrass ( lolium perenne , agrostis stolonifera , festuca rubra , festuca arundinacea , bromus inermis ) in basin , their drought to lerance indexes , including the planting height , the root growth , the relative water content of leaves , the penetration of membrane , were comprehensively evaluated to compare their drought tolerance 摘要采用盆栽育苗法,在5种冷季型草坪草苗期连续干旱胁迫下测定植株高度,根系生长,叶片相对含水量和质膜透性等抗旱指标,以综合评价5种冷季型草坪草的抗旱性能。
