摘要
在内蒙古赤峰地区对引进国内外的35个紫花苜蓿(Medicago sativa)品种进行田间试验,比较了生长第2年的越冬率及不同茬次的株高、鲜草产量、干草产量、叶茎比等各项农艺性状指标的差异,并通过灰色关联分析综合评价不同苜蓿品种的生产性能。结果表明,在种植第2年,综合评价最优的参试品种是龙牧806,其次是飞马、肇东、龙牧801、公农1号等,这些苜蓿品种均为适宜在赤峰地区推广种植的优良品种,而肇东苜蓿、龙牧系列、公农1号与敖汉苜蓿越冬率相对较高,生产性能在综合评价中表现良好,其全面的特点更适合在赤峰市气候偏冷的北部旗县地区推广应用。
A field experiment of 35 introduced varieties of alfalfa （Medicago sativa ） was performed in Chifeng area to compare the differences in winter surviving rate, plant height, fresh yield, hay yield, leaf to stem ratio in the second growth year; and the productive adaptability of 35 varieties were also evaluated with gray correlation analysis. The results indicated that Longmu No. 806 was the best on its comprehen- sive characteristics, while Grandeur, Zhaodong, Longmu No. 801 and Gongnong No. 1 were in the seond best group. These cultivars deserve popularization in Chifeng area. Zhaodong, Longmu, Gongnong No. 1 and Aohan Alfalfa with higher winter surviving rates and excellent comprehensive characteristics were more suitable to be extended in the colder climate of northern counties of Chifeng area.
