摘要
天兰苜蓿（ＭｅｄｉｃｏｇｏｌｕｐｕｌｉｎａＬ．）广泛分布世界各地，已有栽培种。野生原种采自罗甸县（海拔５０２ｍ）、惠水县（海拔１１２０ｍ）、威宁县（海拔２３７０ｍ）。经引种驯化后主要特征是：产草量中等，与公顷可产鲜草３０．０～３７．５ｔ，产纯净种子７５０～９１５ｋｇ。营养成分好，适口性强；能耐寒、抗旱，抗热；种子成熟植株仍保持绿色；当年种子落地可形成新的株丛，是草地改良最佳补播草种和人工草地的混播草种。
Black medick (Medicago lupulizia L. )distributed extensively over the whole world , there had been somecultivars. The wtid local materials were collected from Luodian twith 502 m of elevation) , Huishui (with1120 m of elevation)and Weining (with 2370 m of elevation) . After introduction and domestication ,it showedthat the fresh forage yield was 30～37. 5 t/ha, and seed yield 750～915 kg/ha. It possessed rich nutritioussubstance, good palatability and resistance to cold,drought and hot. The plant kept green when its seed ma-tured. Its dropping seeds can grow up into new plants in the year. It is one of the optimum resowing cultivarfor improving natural grassland , and also can be mixture-cropped for establishing artificial pasture.
