摘　　要：研究了8个甜高粱(Sorghum bicolor subsp.bicolor)品种(系)在盐碱地上的产草量、营养及饲用价值。结果表明,不同甜高粱品种(系)的鲜草产量和叶茎比有显著差异,干鲜比差异不显著。8个品种(系)中,鲜草产量在70000kg.hm-2以上的品种(系)有3个,其中产量最高的为济甜11-8,达到86 194.31kg.hm-2,说明在盐碱地上种植甜高粱作为饲草饲料具有可行性。进一步通过营养和饲用价值比较,选出济甜1号、济甜11-1和济甜11-8三个品种(系),作为适宜黄河三角洲盐碱地种植推广的饲料作物新品种(系)。Eight sweet sorghum cul saline soil. The results showed th tivars （lines） were studied on forage yield, at there were significant difference on forag and no significant difference on dry to fresh weight ratio among all cultivars （1 eties with fresh forage yield over 70 000 kg ha^-1, while Jitian11-8 reached showed the feasibility that a forage crop could be planted on saline soil. By co nutrition and feeding value in e yield and leaf to stem ratio, ines）. There were three vari-86 194.31 kg· ha^-1, which mparing nutritive and feeding values, Jitian No. 1, Jitian 11-1 and Jitian11-8 could be used as new sorghum cultivars （lines） to plant in saline soil of Yellow River Delta.
