【摘要】 采用田间随机区组试验方法,分析评价了50个紫花苜蓿品种在黄河三角洲盐碱地区连续3年的株高、产量等性状指标,以期筛选出适合该地区种植的紫花苜蓿品种。结果表明:不同苜蓿品种的生产性能差异较大,四季旺在黄河三角洲盐碱地区不能正常生长。3年生长过程中‘SR4030’、‘中苜1号’、‘55V12’、‘中苜2号’、‘巨能6’、‘巨能551’、‘新牧2号’、‘鲁苜1号’等品种株高和产量均表现较好,其中‘,SR4030’年干草总产量最高达20.53 t/hm~2,株高最高达76.50 cm‘;龙牧806’‘、草原3号’‘、大富豪’、‘DLF-194’、‘皇后’、‘阿尔冈金’、‘苜蓿王’、‘敖汉’等品种株高和产量均较低。总体而言,不同苜蓿品种干草产量和株高随茬次增加呈降低趋势。‘SR4030’的生产性能最好,是最适宜在黄河三角洲盐碱地区种植的品种,其次为‘中苜1号’‘、55V12’‘、中苜2号’等品种。更多还原

【Abstract】 To select alfalfa varieties adapting in saline areas of the Yellow River Delta, a three-year field experiment of complete randomized block was conducted to compare the plant height and hay yield of 50 alfalfa varieties. The results showed that: the production performance of different alfalfa varieties were different, except that‘Sijiwang’could not grow normally; the varieties‘SR4030’,‘Zhongmu No.1’,‘55 V12’,‘Zhongmu No.2’,‘Magna 6’,‘agna 551’,‘Xinmu No.2’and‘Lumu No.1’had higher hay yield and plant height, and the above two indexes of‘SR4030’reached 20.53 t/hm~2 and 76.50 cm, respectively; on the contrary, the hay yield and plant height of‘Longmu No.806’,‘Caoyuan No.3’,‘Dafuhao’,‘DLF-194’,‘Alfaqueen’,‘Aergangjin’,‘Alfaking’and‘Aohan’were lower. Overall, the hay yield and plant height of different alfalfa varieties decrease with the increase of stubble.‘SR4030’ has the best production performance, and is most suitable for planting in saline areas of the Yellow River Delta, followed by‘Zhongmu No.1’,‘55 V12’and‘Zhongmu No.2’.更多还原
