Abstract: The fall dormancy levels of 11 different alfalfa cultivars were evaluated by measuring fall regrowing height. The evaluating criterion of fall dormancy in Lanzhou was determined and the fall dormancy class of Gannong No.5, Cossack and Sun-god was evaluated. Results showed that the suitable cutting period of alfalfa in Lanzhou was in early September and the measuring period of regrowing height was in early October. The fall dormancy class of Gannong No.5, Cossack and Sun-god cultivar was 11, 3 and 7, respectively.

Key words: Alfalfa, Fall dormancy, Fall regrowing height

摘要: 以11个不同秋眠级苜蓿(Medicago sativa)品种为材料,通过对其秋季再生高度的测定,研究了苜蓿秋眠性在兰州地区的评定技术标准,并对甘农五号、哥萨克、太阳神进行了秋眠级的评定。结果表明:在兰州地区测定苜蓿秋眠性应在9月初刈割,10月初测定其再生高度;甘农五号的秋眠级为11,哥萨克的秋眠级为3,太阳神的秋眠级为7。
