摘　　要：为了筛选出适宜于北疆平原荒漠区种植的高产优质饲用高粱品种,在呼图壁旱生牧草种子基地采用随机区组试验设计,连续两年开展了不同高粱属饲草品种的比较试验。研究结果表明,10份高粱属饲草品种中甜高粱F10、1180、2180、3180和极光的生育期较长,在刈割前一直处于营养生长期,金冠和红岩进入乳熟期,属早熟品种,甜高粱3701、1230和海狮达到灌浆期,属中熟品种。甜高粱3701和海狮的植株高度均在350 cm以上,显著高于其他品种。两年的产量综合评价显示,海狮的鲜干草产量均较高,鲜草为7 324.98 kg/667 m2,干草为2 212.23 kg/667 m2,初步判定可将其作为当地高产优质饲用高粱的备选品种,甜高粱3701和1230鲜草产量也相对较高,植株青绿多汁,可用于制作青贮饲料。In order to screen out the high-yield and high-quality forage of sorghum genus suitable for planting in the desert area of the northern plain of Xinjiang, a comparative experiment on different forage species was carried out in the seed plot of Hutubi dry grass forage for two consecutive years. The results showed that,among the10 forage species, sweet sorghum F10, 1180, 2180, 3180 and Aurora had a longer growth period,they had been in the vegetative growth period before castration;the Golden Crown and Red Rock species entered the milk ripening stage, which was precocious species;sweet sorghum 3701, 1230 and Sea Lion reached the filling stage, which belonged to the medium-maturing species. The heights of sweet sorghum 3701 and Sea Lion were all above 350 cm, which were significantly higher than other species. The comprehensive evaluation results of the two-year output showed that, the outputs of both fresh and dry forage of Sea Lion species were higher, which were 7 234.98 kg/667 m2 for fresh grass and 2 122.23 kg/667 m2 for hay,therefore, Sea Lion was initially determined to be an alternative species of high-yield and high-quality forage.Besides, the yield of fresh grasses of sweet sorghum 3701 and 1230 was also relatively high, and the plants were green and juicy, which can be used to make silage.
