摘　　要：1998-2001年对引自国外和国内部分省（区）的4科29种96个牧草品种进行了物候期及生产性能试验研究。结果表明，不同来源的草种其生长发育差异较大。14个杂交高粱品种和23个紫花苜蓿品种在独山种植基本不结实。青草年产量〉4000kg／667m^2、种子产量〉25kg／667m^2的品种有13个。采用不同繁殖方式在省内外示范推广高产优质牧草5．33万hm^2,为进一步开发利用引种优质牧草资源提供参考。The phenophase and production performance of 96 forage varieties from 29 species in 4 families were studied from 1998 to 2001. The results show that there is the significant difference in the growth and development among tested forage grass varieties from different resources and 14 hybrid sorghum and 23 alfalfa varieties do not fructification in Dushan County. The green grass yield per year and seed output of 13 tested varieties is more than 4000 kg/667m^2 and 25 kg/667m^2 respectively. 53.3 thousand ha of good forage grass with higher yield has been demonstrated and populated by different reproductive methods in Guizhou province and other provinces of China which is benefit for developing and utilizing quality forage grass resources further.
