摘要
对内蒙古呼伦贝尔草原的野生黄花苜蓿进行了多年的栽培驯化研究,结果表明:黄花苜蓿栽培品系与野生群体相比返青早,生长速度快;株型直立或半直立,植株高度、分枝数量、叶量等性状均优于野生群体;平均鲜、干草产量分别比野生原始群体提高2.5倍和1.3倍,比敖汉苜蓿增产15%和4%,在内蒙古东部高寒地区表现出较强的适应性,综合性状明显优于野生群体和对照品种。
The domestication of wild Medicago falcata in Hulunbeier grassland in Inner Mongolia was studied. The results indicated that Medicago falcata cultivation strain turned green early, grew quickly, plants were erect or semi-erect, and higher, had more branches and leavers, higher yield compared with wild Medicago falcata. It's fresh herbage yield and hay yield were increased by 2.5 times and 1.3 times respectively than wild Medicago falcata. and increased by 15% and 4% respectively than Medicago sativa L. cv. Aohan. This new strain showed better adaptation in Inner Mongolia,which was superior in comprehensive traits to wild Medicago falcata and Medicago sativa L. cv. Aohan.
