摘　　要：为筛选适宜于成都平原地区种植的高产优质高丹草(Sorghum bicolor×S.sudanense)品种,2018-2020年在成都平原地区对4个高丹草品种进行大田试验,对其物候期、农艺性状及干草产量进行测定,其中产草量进行了3年测定,其他指标为第1年测定,并采用灰色关联度分析法对4个品种的7个生长指标进行综合评价。结果表明:在生长特性方面,‘蜀草1号’、‘冀草2号’的株高最高,‘JC-009’的叶片数、分蘖数、叶宽及干草产量最高,茎叶比最小。应用灰色关联度对4个高丹草品种进行综合评价得出,‘JC-009’较其他品种更适宜在成都平原地区推广种植。To screen for high yield and high-quality Sorghum bicolor×S.sudanense cultivars in the Chengdu Plain.Field experiment of four cultivars were conducted in the Chengdu Plain from 2018 to 2020.The phenological phase,agronomic traits,and hay grass yield were measured;only the grass yield was measured for three years,and others were measured in the first year.Seven growth indexes were comprehensively evaluated by the grey relational degree analysis method.The results showed that in terms of growth characteristics,‘Shucao No.1’and‘Jicao No.2’had the highest plant height.The leaf number,tiller number and leaf width of‘JC-009’were the highest,and‘JC-009’had the highest hay yield and the lowest stem/leaf ratio.The comprehensive evaluation of the four cultivars using the grey relational degree indicated that‘JC-009’was more suitable for planting in the Chengdu Plain.
