摘要
苜蓿的持久性和草产量是体现生物量的指标,也是引种的重要指标。为筛选出适宜在河西走廊广泛种植的持久性好、草产量高的紫花苜蓿品种,在大田条件下通过对35个紫花苜蓿品种第10年的草产量、株高、生长速率、间隙及分枝数等因素进行观测和分析,结果表明:1)持久性较强的品种有:润布勒、渭南、公农1号和甘农2号等;2)草产量较高的品种有:新疆大叶、公农1号、Bear No.1、润布勒、YL-3和公农2号等;3)综合持久性和草产量等因素筛选出比较适宜在河西走廊种植的优良苜蓿品种为:公农1号、新疆大叶、公农2号、润布勒和渭南等。
Persistence and forage yield are two important indexes in the introduction of new varieties.To select suitable varieties,35 Medicago sativa varieties which were planted in Zhangye Experimental Station of Lanzhou University in 2001 were investigated in 2011.The characteristics studied included persistence,hay yield,growth rate,and plant height.Gaps and branches were also measured.1） The varieties with highest persistence were Prime,Weinan,Gongnong No.1,and Gannong No.2; 2） The varieties with best yields were Xinjiang daye,Gongnong No.1,Bear No.1,Rambler,YL-3 and Gongnong No.2; 3） The varieties with both high yield and persistence were Gongnong No.1,Xinjiang daye,Rambler,Gongnong No.2,Prime and Weinan.These varieties have good adaptability in the Hexi Corridor of Gansu province and are suitable for cultivation in this region.
