摘要: [目的]为筛选出适合于洞庭湖区气候条件下优质紫花苜蓿品种,[方法]本试验于湖南省常德市汉寿县洞庭湖区对14个紫花苜蓿(Medicago sativa)品种产量和品质性状进行了综合评价,[结果]结果表明:播种第一年共刈割5茬,第一茬干草产量为全年最高,随着茬数的增加干草产量呈现递减的趋势;全年平均株高与秋眠级存在极显著正相关关系(P<0.01),秋眠级高的品种株高显著高于秋眠级低的品种。所有供试品种干草品质均达到特级或一级标准,[结论]其中WL525、55v12、吉利、南苜701、WL656等5个品种各项指标表现较好,综合排名靠前,适宜于湖南洞庭湖区生长。

Abstract: To screen out high quality alfalfa varieties suitable for the climate of Dongting Lake area, the yield and quality characteristics of 14 varieties of alfalfa were evaluated in Hanshou County, Changde City, Hunan Province. The results indicated that the first year of planting had five times mowing, the first batch hay yield was the highest, and the yield of hay decreased with the increase of the mowing number. There was a significant correlation between the average height of the whole year and the dormancy grade (P<0.01), the plant height of the high dormancy grade variety was significantly higher than that of the low dormancy grade variety. The quality of all varieties of hay reached the special grade or primary standard, and five varieties ‘WL525’,‘55v12’,‘Jili’,‘Nanmu 701’,‘L656’ranked top, suitable for growing in Dongting Lake area.
