摘    要:分析了亚高山草甸的苔草、狼针草、羊茅、细茎鸢尾、裂叶蒿、蓝花棘豆6种牧草在各个生育期的粗脂肪、粗蛋白质、酸性洗涤纤维(ADF)和钙、磷等营养成分的含量。结果表明,牧草中各种营养成分的含量动态与生长发育阶段密切相关。粗蛋白质和磷随生育期逐渐减少;ADF和钙含量随着生育期逐渐增加。

关 键 词:牧草 营养动态 营养成分 生育期

Abstract:The contents of crude protein, crude fat, ADF, calcium and phosphorus in Carex subpediformis, Stipa baicalensis, Festuca ovina, Iris ruthenica, Artemisia tanaoetifolia, and Oxytropis coerulea were analyzed. The result showed that: the trend of all kinds of nutritive composition was related to varieties and stage of growth and development. The contents of crude protein and phosphorus decrease with the growth and development of it . The ADF and calcium increases with the growth and development.
Keywords:Herbage   nutritive trends   nutritive compositon   stage of growth and development
