摘　　要：为筛选适宜冀西北地区种植的饲用谷子品种,本试验选取28个饲草专用型谷子对其生产性能及营养品质进行综合比较。结果表明,饲草谷株高变异范围为164.93~211.58 cm,鲜草产量变异范围为23647.7~106237.21 kg/hm^(2),干草产量变异范围为5593.68~26036.65 kg/hm^(2)。饲草谷12号和25号叶茎比高于其他品种,25号鲜草产量最高,17号生物产量最高。饲草谷粗蛋白质变化范围为10.1%~12.8%,酸性洗涤纤维变化范围为35.7%~44.4%,中性洗涤纤维范围为55.6%~68.1%。不同饲用谷子相对饲喂价值和相对牧草价值差异显著,分别为74~103和81~124。隶属函数分析不同谷子生产性能及营养品质,晚熟品种饲草谷25号、28号,中熟品种饲草谷10号、5号和2号,早熟品种饲草谷20号、21号和16号综合性能高。In order to screen forage Setaria italica varieties suitable for planting in northwest Hebei province,the production performance and nutritional quality of 28 forage millet varieties were analyzed.The leaf-stem ratio of c.v.12 and c.v.25 was significantly higher than that of other varieties,c.v.25 also had the highest fresh yield,highest hay yield gained by cv.17.The plant height of different varieties ranged from 164.93 to 211.58cm,fresh yield ranged 23647.7~106237.21 kg/hm^(2),hay yield ranged 5593.68~26036.65 kg/hm^(2).The crude protein content of millet varieties varied from 10.2%~12.8%,ADF content varied from 35.7%~44.4%,NDF varied from 55.6%~68.1%,respectively.Relative feed value ranged 74~103 and relative feed quality ranged 81~124.Combining with the climatic characteristics of northwest region,the late-maturing millet c.v.25 and c.v.28,the medium-ripe varieties 10 Hao,5 Hao,and 2 Hao,the early maturing varieties 20 Hao,21Hao and 16 Hao were more advantageous than other millet.
