为了探讨国外苜蓿品种在吉林中部地区的表现及苜蓿农艺性状间关系,试验测定了16个丹麦苜蓿品种与2个国内品种的鲜草产量、秋眠性、花期等农艺性状。结果表明:丹麦苜蓿品种与国内苜蓿品种相比不存在生产性能优势;农艺性状间存在一定的相关性,其中鲜草产量与花期早晚、田间密度密切相关,秋眠性与花期早晚、抗倒伏能力密切相关。
In order to study the relationship between the performance of alfalfa varieties in central Jilin and the agronomic characters of alfalfa, the agronomic traits of fresh production, fall dormancy and anthesis of 16 Danish alfalfa varieties and 2 domestic varieties were tested. The results showed that there was no productive superiority among Danish alfalfa cultivars and domestic alfalfa cultivars. There was a certain correlation between agronomic traits. The yield of fresh grass was closely related to the flowering period and the field density, and the fall dormancy and anthesis lodging ability closely related.
