摘要 偃麦草为禾本科偃麦草属牧草,从新疆伊犁草原采集野生种子进行人工栽培驯化,获得成功。在良好的耕作条件下,加上人工选择的结果,使得种性有所改变,象经济性状、生物学特性等日趋向着人们需求的方向变异。植株变得高大,产量提高,化学成分等亦有变化。每亩干草产量200~300kg,种子20~30kg;饲用价值高,含粗蛋白质11.05%,粗脂肪3.53%;适口性好,各类家畜均喜食;除用作放牧及饲草外,还可用作水土保持。 Elytrgia repens belong to Elytrigia forage of Gramineae. The wild species collected from YiLi Xinjiang have been cultivated and domesticated successfully. Under the excellent cultivated condition and the artificial selection, some economic and biological characterstics of species would meet the human needs gradually. Plant becomes large with bigh production, hay 200-300kg mu, seed 20-30kg/mu. The chemical composition of plant has become difference such as high edible, 11.05%crude protein, 3.53% crude fat. In addition they are used as forage and in grazing, they are available to soil and water conservation.
