摘　　要：为筛选出江淮地区种植的黑麦草品种,试验选择了沃土、蓝天堂、钻石、特高4个黑麦草品种,分别在黑麦草的分蘖期、拔节期、初花期等时期进行了自然高度、分蘖数、叶绿素含量、叶面积指数和鲜重产量的比较研究。结果表明:通过对测量数据的整理和分析,得出了4个品种中沃土品种在各方面都有明显优势,而且在整个生长过程中并没有出现病虫害。所以从试验的结果来看,沃土品种较适宜在江淮地区引种生产。In order to screen ryegrass varieties which adapted to Huai river region in Anhui province,the natural height,tiller number,leaf-area-index（LAI） and chlorophyll content and fresh weight of four ryegrass varieties,including Fertile soil,Blue heaven,Diamond and Ultra high were investigated at tillering stage,jointing stage and the early flowering stage.The results showed that through the collation and analysis of data obtained,fertile soil had a distinct advantage in plant height,growth rate and yield from other three varieties,and in the whole growth process there wasn＇t any pests infected.Therefore,based on the results,the conclusion was that fertile soil was more appropriate introduced production in Huai river region.
