| 摘 要： | 在西藏那曲县研究了"冬圈夏草"的适应性,种植羊圈10个,每个羊圈约900 m2。采用单播8种饲草,混播6种组合。结果表明,各处理牧草生长旺盛,产草量高,生长期延长,可延迟至10月底进行收割,此时禾本科饲草料生育期为抽穗期,高度在1 m左右,平均鲜草产量高达28 500 kg/hm2以上。"冬圈夏草"种植简单,可有效缓解春季饲料缺乏的问题,值得推广。

| Abstract: | In 2005 and 2006,five households in Nagchoe County of Tibetan Autonomous Region were selected to conduct experiments on the grass sowing in sheep pens.10 pens,around 900 m2each,were planted with forages.Barley(Hordeum sativum),oat(Avena sativa),rapeseed,Vicia sativa,Annual Medicago spp.,Astragalus adsurgens,Onobrychis vociafolia,were used for sole planting and 6 combinations were used,including "barley rapeseed","barley Vicia sativa","oat annual Medicago spp.","oat Astragalus adsurgens","oat barley","oat barley Onobrychis vociafolia".The result indicated that all grasses could grow well and achieve high production.The average height was around 1 m and the average fresh matter yield was over 28 500 kg/hm2.This suggested that sowing grass in sheep pen was a proper technique to be extended in order to resolve the forage shortage in winter and spring. |
