摘    要:摘要:2003-2006年元谋干热河谷对16个豆科牧草进行引种试验,结果表明,参试材料中,除蝴碟豆(Centrosema pubescens)、大叶千斤拔(Flemingia macrophylla)和卵叶山蚂蝗(Desmodium ovalifolium)由于气候差异性不能结实外,其他牧草均能适应该地区种植。其中,银合欢属表现出产量高、叶量大、适口性好等特点。产量排列前3名的牧草为银合欢(Leucaena leucocephala)K636、新银合欢和热研1号银合欢,干草产量分别为26 933.9、24 882.6和22 459.2 kg/hm2,羊对这3种牧草特别喜食。其次是提那罗新罗顿豆(Neotononis wightii),表现出叶量大、干鲜比低等特点,其干鲜比为0.27,茎叶比为0.73,羊对其特别喜食。卵叶山蚂蝗产量最低,茎叶比最高,其干草产量为920.8 kg/hm2,茎叶比为1.96,不适宜作该地区的牧草生产草种。克拉豆(Cratylia argentea)花期应注意防治害虫,提高结荚率。
