摘　　要：对不同休眠级别的四个紫花苜蓿品种赛迪10、赛迪7、赛迪5和游客进行区域试验研究,以游客作为对照品种,通过观察物候期、生物产量、适应性及形态学特征等指标,综合评述了三个新品种在福建省福州和三明清流县示范点的表现,赛迪10丰产性最好,增产潜力大,平均亩产鲜草量高达5920.07kg,比对照增产18.65%,分枝数达45.6个,刈割前的茎叶比为0.75;赛迪7平均亩产鲜草量为5405.81kg,增产8.35%,分枝为43.8个,刈割前的茎叶比为0.83。筛选出赛迪10和赛迪7两个新品种适宜在福建省进行种植。Four different winter dormancy of alfalfa, Sadie 10, Sadie 7, Sadie 5 and CK were selected to do regional test. Taking CK as the control variety, through observing the indexes as phenol-phase, biomass output, adaptability and morphological characteristics, the three new varieties introduced in Fuzhou and Qingliu County of Fujian province were comprehensively evaluated. Among the three, Sadie 10 was optimal in output, with a huge potential for increasing yield, and an average yield of 5920. 07 kg/mu, which increased 18.65% than the control, and the number of branches were 45.6, and the leaf to stem ratio before cutting was 0.75; while the mean yield for Sadie 7 was 5405.81 kg/mu, increased by 8.35%, and 43.8 branches, with a leaf to stem ratio of 0.83. It is concluded that Sadie 10 and Sadie 7 are suitable to be planted in Fujian province.
