摘　　要：试验为进一步筛选适宜天津地区种植的饲用高粱属作物品种。基于2019年的田间试验结果,对已经筛选出的9个饲用高粱属作物品种,于2020年再次进行品种比较试验,进一步评价其在天津地区的适应性和稳定性。结果表明,不同品种之间的物候期存在差异,苏丹草和辽甜3号的株高均高于400 cm,显著高于其他品种(P<0.05)。辽甜3号和辽甜1号的鲜草产量较高,显著高于其他品种(P<0.05)。干草产量排在前三位的分别是苏丹草A506XR43-03、辽甜1号、辽甜3号,分别达到21.79、21.68、21.04 t/hm^(2)。9个饲用高粱属作物的粗蛋白、中性洗涤纤维、酸性洗涤纤维、醇溶糖、脂肪、淀粉等营养成分含量均具有不同差异。经过连续两年的品种比较试验发现,冀草8号、辽甜1号、苏丹草A506XR43-03的干草产量呈现增加趋势。研究表明,在高丹草中选择冀草8号,饲用甜高粱中选择辽甜1号,苏丹草中选择苏丹草A506XR43-03,以上3个品种与同类别饲用高粱属作物相比在当地的适应性较好,可以作为天津地区优质饲草品种推广应用。The experiment was to further screen forage sorghum cultivars suitable for planting in Tianjin.Based on the field test results in 2019,a variety comparison test was conducted again in 2020 to further evaluate the adaptability and stability of nine forage sorghum varieties in Tianjin area.The results showed that there were differences in phenological period among different cultivars,and the plant height of Sudan grass and Liaotian No.3 was higher than 400 cm,which was significantly higher than that of other cultivars(P<0.05).The fresh grass yield of Liaotian No.3 and Liaotian No.1 was significantly higher than that of other cultivars(P<0.05).The hay yield of Sudan grass A506XR43-03,Liaotian No.1 and Liaotian No.3 reached 21.79,21.68 and 21.04 t/hm2,respectively.There were differences in the content of crude protein,neutral detergent fiber,acid detergent fiber,alcohol-soluble sugar,fat and starch among nine forage sorghum varieties.The hay yield of Jicao No.8,Liaotian No.1 and Sudan grass A506XR43-03 showed an increasing trend after two consecutive years of comparison test.The study indicates that Jicao No.8 is selected from the Gaodan grass,Liaotian No.1 is selected from forage sweet sorghum,Sudan grass A506XR43-03 is selected from Sudan grass,the above three varieties have better adaptability in local area,which can be used as the better choice for the promotion of high-quality forage varieties in Tianjin area.
