摘　　要：为在闽北红壤区推广种植优质牧草，１９９０年引进４０个国内外热带品种，在福建省建阳市试种。按《印尼植物基因资源田间评价》方法进行观察记载，并进行综合评价，筛选出圆叶决明（Ｃａｓｉａｒｏｔｕｎｄｉｆｏｌｉａ）、南非马唐（Ｄｉｇｉｔａｒｉａｓｍｕｔｓｉ）、平托花生（Ａｒａｃｈｉｓｐｉｎｔｏｉ）等３个优良多年生热带牧草品种。３个品种均表现高产、优质，圆叶决明耐瘠、抗旱力强，适宜在瘠薄的红黄壤旱地种植；平托花生为匍匐性植物，覆盖性好，耐铝性强且较耐荫，适宜在茶、果园中套种；南非马唐根系发达，固土能力强，尤其适宜在茶、果园的梯壁上种植。In order to popularize and plant the excellent forage in red soil region of Northern Fujian,40 tropical species were introduced to Jianyang,Fujian province.The trial of these species was observed in way of “Field Evaluation of Plant Gene Resource in Indonesia”.Three promising accessions of perennial tropical forage were selected.They were Cassia rotundifolia,Digitaria smutsii and Arachis pintoi, all of them showed the characteristics of high yield and good quality. Cassia rotundifolia showed the characteristics of resistance to barren and drought,it suitable for being planted in barren red yellow soils. Arachis pintoi showed the characteristics of creep and resistance to Al and shade,it suitable for being interplanted with tea garden and orchard. Digitaria smutsi showed the ability of surviving winter and control soil erosion for its strong root,it suitable for being planted on the terrance of the tea garden and orchard.
