【摘要】 青海省是我国五大牧区之一,长期以来畜牧业发展主要依赖天然草场。皮燕麦(A.sativa.L.)作为青海高寒牧区人工草场主要优质饲苹饲料作物之一,具有营养高,适口性好的特点。今后,应该大力发展以皮燕麦为主的人工草场生产,减轻由于过度放牧对天然草场的压力,恢复和保护高原脆弱的生态环境。更多还原

【Abstract】 Qinghai province is a one of the five great pasturing zones in China, but stockbreeding in this area are mostly depend on nature grassland since antiquity time. Husk oat (A. sativa . L. ) , which is main one of forage-grass at artificial grassland, has high quality, good nutrition and it is suitable edibility at this high altitude and cold climate pasturing-grassland area in Qinghai province. Thus we should develop the artificial grassland in this area in order to alleviate over-feed stress for nature grassland and to restoration and protection the frail eco-environment in this plateau.更多还原
