摘要
大穗雀麦为禾本科雀麦属牧草,从伊犁草原采集野生种进行人工栽培驯化,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,‘生物学特性等日渐向着人们需求的方向变异。如植株变得高大密集,产量提高,化学成分等亦有变化。它生育期短,仅70天左右;亩产干草100～200公斤,种子80～100公斤;种子发芽率百分之百;饲用价值高,粗蛋白质含量11.64％;适口性好,各类家畜均喜食;既可作为打草场种植,又可作为改良退化草场的先锋植物栽培。
Bromus macrostachys belong to Bromus forage of Gramineae. The wild species collected have been canied on cultivation and met with success. In the excellent condition cultivated and the result of artificial selection, some characters of species varied with humeris needs as economic character step by step, Biological characters etc. Such as, plant changing hight and dense , increasing field and also changing chemical compositions etc. Their adoantage are:grouwth period short, only 70days, hight field, 100-200kg/acrehay, 80-100kg seed; highter germina-tive rate 100％; highter edible value, protein content 11.64％, good phagotrophy, Adaptability is not only as mow grazing, but also as pioneer plant cultivation it improve deteriorative grazing, and as use organic material of breeding.
