【摘要】 为了筛选出适合湖南人工栽培的龙须草优质品种,在相同栽培生态条件下,观测、比较分析了引自四川巫山、湖北丹江和湖南慈利的龙须草的生产性能.结果表明:从出苗率、草苗素质、还苗率、分蘖速率、干物质积累和纤维素含量6个方面综合评价,湖北丹江的龙须草品种最优,四川巫山的其次,湖南慈利的最差.3个参试品种的隔年种子出苗率均极显著地低于当年新种子.更多还原

【Abstract】 In the same ecological conditions,productive properties among 3 varieties of Eulaliopsis binata (Retz) obtained from Wushan of Sichuan province,Danjiang of Hubei province and Cili of Hunan province respectively were studied during 1997~1998 to select a high quality variety which is fit for artificial cultivation in Hunan.Results obtained showed that Danjiang variety was the best variety,Wushan variety was the second and Cili variety was the worst according to rate of emergence,performance of seedling,survival rate of transplanted seedling,tiller rate of plant,dry matter accumulation in aerial part of plant and cellulose contents in leaves. It was also known that rate of emergence for last year seed was notably lower than present year seed in these 3 varieties.更多还原
