摘　　要：以美国标准秋眠性苜蓿品种(1～11级)为材料,在昆明自然条件下,研究苜蓿秋眠性在云南的评定技术标准。结果表明,在昆明测定苜蓿秋眠性应在11月初刈割,11月末或12月初测定其再生高度。秋眠性等级高的苜蓿品种在云南有较好的地区适应性,特别是在秋冬季具有较好的生长势和较高的产草量。引入秋眠性等级高的苜蓿品种是解决云南缺乏优质豆科牧草,特别是冬季优质牧草不足的重要措施。The standard fall dormancy alfalfa varieties from the U.S.A.were studied in order to determine the evaluating criterion of the fall dormancy in Yunnan Province. The experiment was controlled under the natural condition in Kunming, Yunnan Province. The results showed that the measuring stage for alfalfa fall dormancy in Yunnan Province are:the considerable cutting period was suggested, in early November and the measuring period of regrowing height was suggested in late November or early December. The high grads of the fall dormancy of alfalfa have the good adaptation in Yunnan Province, especially for the better growth and higher yields in autumn and winter. It is the major method that introducing alfalfa varieties with the high grads fall dormancy to solve the problem for the lack of legume forage with the high quality in Yunnan Province, especially in winter.
