摘　　要：【目的】探究干旱区过渡地带7个禾本科牧草种植生产价值,为本地区种植禾本科牧草提供品种选择支撑。【方法】本研究选取粮饲兼用玉米科桦669、绿博6号、甜高粱、苏丹草、高丹草、巨菌草和金牧粮草7种饲用作物为研究对象,同一水肥条件下,对比分析其农艺性状、干草产量、营养成分、相对饲用价值和种植经济效益,并结合各指标进行灰色关联度分析。【结果】科桦669、绿博6号干草产量分别为25225.07 kg/hm^(2)、23692.55 kg/hm^(2);相对饲用价值分别为170.88、147.97;经济效益分别为16150.26元、14203.38元。灰色关联度分析排序为科桦669>绿博6号>巨菌草>金牧粮草>高丹草>甜高粱>苏丹草。【结论】表明玉米品种科桦669、绿博6号更适宜在干旱半干旱地区过渡地带水地种植。【Objective】The planting value of seven grass grasses in the arid areas was investigated to provide theoretical support for the variety selection of grasses planted in this area.【Method】Seven forage crops including Ke-hua 669.Lvbo 6,Sweet Sorghum,Sudan grass,Sorghum sudanense,Pennisetum sinese and Jinmu forage were se-lected as the research objects.Their agronomic traits,hay yield,nutrient content,relative feed value and planting eco-nomic benefits were compared and analyzed under the same water and fertilizer conditions,and the grey correlation de-gree analysis was carried out in combination with various indicators.【Result】The results showed that the hay yields of Kehua 669 and Lvbo 6 hay were 25225.07 kg/hm^(2) and 23692.55 kg/hm^(2),respectively.The relative feeding value was 170.88 and 147.97,and the economic benefits were 16150.26 yuan and 14203.38 yuan,respectively.The order of grey correlation was Kehua 669>Lvbo 6>Pennisetum sinese>Jinmu Forage>Sorghum suda-nense>Sweet Sorghum>Sudan Grass.【Conclusion】Comprehensive analysis shows that maize varieties of Ke-hua 669 and Lvbo 6 are more suitable for planting in water land in the transition zone of arid and semi-arid areas.
