白羊草 meaning in Chinese
bothriochloa ischiemum keng
Examples
- Analysis of the reproductive - tiller quantitative characters of bothriochloa ischaemum populations
白羊草种群生殖分蘖株数量特征分析 - Bothriochloa ischaemumis the dominant species in all the plots , while the other species flourish or decline successionally at different grazing stages
在不同的利用阶段，白羊草种群都是优势种，而其他植物种则呈现不同的趋势。 - In different phases of development , vegetation systems in this region have changed from pioneer herbage species initially recovering in abandoned cropping lands ( bothriochloa ischemum , artenmisia giradii and stipa bungeana , artenmisia sacrorum , spodiopogen sibiricus and sophora flavecens , themeda japonica , and arundinella anomala ) to secondary shrubs ( hippophae rhamnoides , sophora viciifdia , and ostryopsis davidiana ) , early forest community ( populus davidiana , betula platyphylla and platycladus orientalis with arbors or shrub assembling ) , and finally liaotungesis community as the mature forest . in this study , soil profiles ( 0 - 5 , 5 - 15 , 15 - 25 , 25 - 35 , 35 - 50 cm soil layers ) were selected from typical vegetation systems representing for vegetation successions in the region
该区北部目前还保存有空间上完整的植被正向演替系列，即弃耕地先锋群落草本群落(白羊草bothriochloaischemum 、茭蒿artenmisiagiradii +长茅草stipabungeana 、铁杆蒿artenmisiasacrorum 、大油芒spodiopogensibiricus +苦参sophoraflavecens 、黄菅草themedajaponica或野古草arundinellaanomala )灌丛群落(沙棘hippophaerhamnoides 、狼牙刺sophoraviciifdia 、虎榛子ostryopsisdavidiana )早期森林群落(乔灌群聚、山杨populusdavidiana 、白桦betulaplatyphylla 、侧柏platycladusorientalis 、 )辽东栎群落( quercusliaotungensis ) 。 - Using the cluster analysis method and studying 16 sampling plots of shrub grassland where bothriochloa ischaemum is the dominant species , and the plots ' grass frequency , grass coverage , density , height , and biomass , we graded the plots into five grazing stages : light , proper , moderate , serious , and extreme
摘要在对放牧利用下的白羊草灌丛草地频度、盖度、密度、高度、生物量等数量特徵调查基础上，运用系统聚类分析方法，可戒分为轻放、适牧、中牧、重牧和极牧五个阶段。
