中文摘要	以中国热带农业科学院已选育成功的热研5号柱花草作对照,对2003年引进的8份圭亚那柱花草种质资源进行比较试验研究.结果表明:参试的柱花草材料在本区均能安全越冬,正常生长.总体看所有参试种叶量比茎多,品质好.按粗蛋白质含量分等级,参试材料中,等级处于上而且比热研5号高的种质有4个,比热研5号草低的有2个.其中GC1557柱花草的干草产量最高,显著高于热研5号,干草产量为17 784.7 kg/cm2/a,综合性状较好,可在云南干热河谷区推广应用.Mineirao柱花草旱季干草产量最高,是全年的13.80 %,具有较强的抗旱能力,可作为旱地种植的材料之一.种植柱花草1年,试验地土壤养分均有明显提高,表明柱花草的根瘤可以固氮,种植柱花草能提高土壤肥力,改良酸性土壤.综合评价认为,柱花草是适应本区种植的优良牧草.
英文摘要	Eight Stylosanthes guianensis were introduced and compared with S.gianensis cv.Reyan No.5 of the Chinese Academy of Tropcal Agricultural Sciences seed selection in the Arid-hot valleys of yuanmou in 2003.The result showed that eight S.guianensis grew well and could get through winter.As a whole,the leaves amount was more than that of stems with higher quality in the experiment.In the light of coarse proteincent to grade in the experiment,higher grade had four and lower had two camparing with S.gianensis cv.Reyan No.5.The average dry weight of S.gianensis GC1557 was the biggest and reached 17784.7 kg/cm2/a,its integrative character were better and could extended in the arid-hot valleys of Yunnan.Ratio of air-dry yield in dry season in a year of S.gianensis Mineirao was the highest and reached.13.80 %,and S.gianensis Mineirao had strong drought resistance and could be good germplasms resource to plant in droughty soil.Soil nutrients increased on demonstration land for planting S.gianensis fir a year.It showed that S.gianensis could fasten nitrogen for root nodule.Planting S.gianensis could increase fertility of soil and meliorate acidic soil.Integrative value showed that S.gianensis was fine grazing planted in this area.
