缘毛雀麦（ＢｒｏｍｕｓｃｉｌｉａｔｕｓＬ．）为禾本科雀麦属多年生草本植物，具短根茎，是易结成草皮的根茎─—疏丛型禾草，产于宝格达山及大兴安岭山地。在我国东北、俄罗斯、蒙古和美国西北部山地也有分布，本野生种采自宝格达山，于１９８８年开始在呼和浩特地区栽培驯化。在驯化过程中，初步测试了它的生物学特性、经济性状和部分生理生化指标，并确定了其染色体数目２ｎ＝５６。在结实期的于草平均产量为９９７５ｋｇ／ｈｍ￣２；粗蛋白质含量１０％，粗脂肪３％，粗纤维３３％，无氮浸出物３９％，灰分８％。粗蛋白质等养分含量、再生速度和叶量均高于无芒雀麦现行栽培品种。现已筛选出草丛类型各异，生育期不同，籽实保持力较强，可以放牧、刈草或兼用等具有广泛用途的几个生物学类群。 Bromusciliatus L. is a perennial Herbaceous Herbaceous herbaceous plant with short rhizomes, which is the rhizome of easy-to-grow turf ─ ─ Shu Cong grass, produced in Baigoda Mountain and the Greater Xing’an Mountains. In northeastern China, Russia, Mongolia and the northwestern United States are also distributed in mountainous areas. The wild species was collected from Baghdad Mountain and began to be cultivated and domestically in Hohhot in 1988. During domestication, its biological characteristics, economic traits and some physiological and biochemical indexes were preliminarily tested, and its chromosome number 2n = 56 was determined. The average yield in the grazing period was 9975kg / hm ~ 2; the crude protein content was 10%, the crude fat was 3%, the crude fiber was 33%, the nitrogen-free extract was 39% and the ash content was 8%. Crude protein and other nutrient content, regeneration rate and leaf volume were higher than the current cultivars of Bromus inermis. Several biological groups have been screened for their wide range of uses, such as different types of grasslands, different growth stages, strong seed-holding capacity, grazing, mowing or both.
