冰草又名扁穗冰草、野麦子。是世界温带地区最重要的牧草之一,广泛分布于西伯利亚、蒙古及亚洲中部寒冷、干旱地区。我国北方诸省(自治区)都有分布。冰草适宜在寒冷干燥地区种植。 一、经济价值 冰草最大的特点是寿命长,耐践踏,防风固沙能力极强,生长快产量高。它草质柔软,适口性良好,一年四季为多种家畜所喜食,马和羊最喜食,有催肥作用。干枯后适口性有所下降,但调制成干草后各种家畜仍很喜食。从其化学组成来看营养价值高,抽穗期的营养价值最好,其粗蛋白质含量占干物质的 Ice grass, also known as flake ice grass, wild wheat. Is one of the most important forages in the temperate regions of the world and widely distributed in cold and arid regions of Siberia, Mongolia and Central Asia. All provinces (autonomous regions) in the north of our country are distributed. Ice grass suitable for planting in cold and dry areas. First, the economic value The biggest feature of ice grass is long life, trampling resistance, strong windbreak sand fixation, fast growing high yield. It is soft in texture and palatability. It is favored by many domestic animals throughout the year. Horse and sheep are the most eaten foods with fattening effect. After drying, the palatability decreased somewhat, but all kinds of livestock were still very much eaten after the hay was prepared. From its chemical composition of high nutritional value, the nutritional value of the heading of the best, the crude protein content of dry matter
