为筛选适宜环县干旱山区种植的饲草高粱品种，以促进当地畜牧业发展，在全膜栽培条件下，对引进的7个饲草高粱品种(系)在环县干旱山区进行了品比试验。结果表明，折合鲜草产量以惊喜最高，为102 705.14 kg/hm2，较对照品种海牛增产30.66%；其次是晋生粱1号，为101 505.08 kg/hm2，较对照品种海牛增产29.13%；大卡排第3位，为100 205.01 kg/hm2，较对照品种海牛增产27.48%。折合干草产量以晋生粱1号最高，为25 062.98 kg/hm2，较对照品种海牛增产21.16%；其次是惊喜，为23 556.22 kg/hm2，较对照品种海牛增产13.88%；大卡排第3位，为23 522.30 kg/hm2，较对照品种海牛增产13.72%。这3个饲草高粱品种在环县种植全生育期营养生长时间长，鲜草产量高，抗旱性极强，综合性状好，建议在环县干旱山区大面积种植。

In order to screen suitable forage sorghum varieties for cultivation in arid mountainous area of Huanxian and to promote the development of local animal husbandry, a comparative experiment was conducted using 7 introduced forage sorghum varieties(lines) under full film cultivation conditions in the arid mountainous area of Huanxian. The results showed that the fresh grass yield of Jingxi was the highest with 102 705.14 kg/ha, which added 30.66% comparing with control variety Manatees, followed by Jinshengliang 1 and Daka with 101 505.08 kg/ha and 100 205.01 kg/ha, which added 29.13% and 27.48% comparing with that of the control variety. The average hay yield of Jinshengliang 1 was the highest with 25 062.98 kg/ha, which added 21.16% comparing with that of the control, followed by Variety Jingxi and Daka with 23 556.22 kg/ha and 23 522.30 kg/ha, which added 13.88% and 13.72%, respectively, comparing with that of the control. These three forage sorghum varieties had a long nutritional growth period, high fresh yield, strong drought resistance, and ideal comprehensive traits during the entire growth period when planted in Huanxian. It is recommended that the three forage sorghum varieties should be planted and popularized in the arid mountainous areas of Huanxian.
