摘要
通过对不同留床紫花苜蓿品种的产量、构成要素、品质及越冬性进行研究,综合分析筛选出河西轻粘土地区适种的紫花苜蓿品种。结果表明:20个留床苜蓿品种干物质产量WL363HQ最高株高以巨能2最高,蛋白质含量最高的是亮苜2号,相对饲用价值(RFV)最高的是巨能2,越冬成活率最高的是巨能551,综合结果显示,阿迪娜,亮苜2号、巨能2和WL363HQ等品种所在的类群综合适应性较好,适宜在河西走廊轻粘土壤种植。
A field survey was conducted to assess the suitability of twenty lucerne(Medicago sativa) varieties to light clay soil in the Hexi Corridor, Gansu Province by using cluster analysis, taking lucerne above yield, basis characteristic, quality, and overwintering percentage as analysis factors. The results showed that the above biomass of WL363 HQ was the highest among the twenty lucerne varieties.The plant height and RFV of Juneng No.2 were the highest among all varieties. The protein content of Liangmu No.2 was the highest. The overwintering percentage of Juneng 551 was better than other varieties. It is suggested that Adina, Liangmu No.2, Juneng No.2 and WL363 HQ were suitable for sowing grasses in light clay soil of Gansu Hexi Corridor according to cluster analysis.
