摘　　要：在西藏自治区那曲高寒牧区开展“冬圈夏草”设施循环利用技术研究,对适宜当地种植的甘引1号、白燕麦、青海444、燕麦林纳、青稞、冬小麦6个牧草品种,在同一水平下进行牧草产量品比试验,筛选出适宜在棚圈种植的牧草品种。研究表明:牧草种子成本及可接受程度,最经济、最适宜、最佳推广种植混播高产品种为甜燕麦、青海444和箭舌豌豆,其播量为18 kg/667 m^(2)+5 kg/667 m^(2),播深4 cm,牧草产量最高。同时,在棚圈种植牧草的实践中,逐步完善棚圈种草技术规程,提出了那曲高寒牧区“冬圈夏草”循环利用模式,解决了冬春季节接羔育幼期间饲草料不足的问题,并引导农牧民自主储备饲草料,为提高幼畜成活率和促进增收提供保障。In the Tibet Alpine pastoral areas of Nagchu,China,to carry out a study on the recycling technology of“Summer grass and winter circle”facilities,six forage varieties,such as Ganyin 1,white oat,Qinghai 444,oat Linna,highland barley and winter wheat,suitable for local planting,were tested for forage yield and quality at the same level.Results showed that:According to the cost of grass seed and the acceptability of common people,sweet oat’Qinghai 444 and common vetch were the most economical,the most suitable and high-yield single-sowing varieties,the forage yield of which was the highest with the sowing rate of 18 kg/667 m2+5 kg/667 m2 and the sowing depth of 4 cm.At the same time,in the practice of planting grass in sheds,the technical regulations for planting grass in sheds have been gradually improved,and a“Winter-circle-summer-grass”recycling model has been proposed in Nagchu's alpine pastoral areas,which is an effective measure to solve the problem of insufficient forage during lambing in winter and spring,guide farmers and herdsmen to reserve forage independently,improve the survival rate of young animals and promote income.
