摘要
2013~2017年,在山东东营地区对14个苜蓿品种进行生产适应性评价,以期筛选适宜黄河三角洲地区种植的苜蓿品种。结果表明:苜蓿年产量在不同年份间具有极显著差异(P<0.01);14个苜蓿品种中4年平均年干草产量居前三位的是中苜3号、中苜2号和WL-SALT;干草产量在各茬次之间存在明显差异,第1茬产量最高,约占年总产量的38%~46%,年产量最高的两个品种的第一茬产量也最高。综合分析4年结果,中苜3号、中苜2号生产性能最好,其次国外品种WL-SALT和WL363HQ表现良好,这4个品种较适宜在黄河三角洲地区种植。
In order to select alfalfa(Medicage sativa L.) cultivars suitable for planting in the Yellow River Delta, a field study was conducted to evaluate the hay yields of fourteen alfalfa cultivars from 2013~2017. The results showed that the annual hay yield of alfalfa was significantly different(P<0.01) in different years. The average annual hay yield of four years in the top three of the 14 alfalfa cultivars was Zhongmu No.3, Zhongmu No.2 and WL-SALT. There was a significant difference in hay yield between each stubble. The two cultivars with yield of first stubble was the highest, accounting for 38%~46% of the total annual yield, the two cultivars with the highest annual yield also had the highest first stubble yield. Comprehensive analysis of the results of four years showed that Zhongmu No.3 and Zhongmu No.2 had the best production performance, followed by WL-SALT and WL363 HQ of foreign cultivars, which were more suitable for planting in the Yellow River Delta.
