中文摘要:通过比较不同紫花苜蓿品种干物质质量分数和营养品质,筛选出适合陕北农牧交错区种植的品种。在田间条件下,采用随机区组试验对14个紫花苜蓿品种的株高、干物质产量和营养品质进行对比研究。结果表明,‘金皇后’、‘WL319HQ’结实期株高显著高于其他供试品种,表明其生长速度和生长能力高于其他品种;‘金皇后’和‘中草5号’总地上生物量显著高于‘陕北’;14个紫花苜蓿品种的粗蛋白质量分数均大于 17.0% ,表明其均能达到一级牧草标准,且‘陕北’的相对饲喂价值均低于其余13个引进苜蓿品种。综上表明,‘金皇后’‘皇后’‘中草5号’‘甘农3号’等紫花苜蓿品种均具有在陕北农牧交错区推广种植的优势。

Analysis of Growth Characteristics and Quality of 14 Alfalfa Varieties in Farming pastoral Area
Abstract:In order to study dry matter content and nutritional quality of different alfalfa,and screen out suitable varieties for traditional farming pastoral area. The growth characteristics and nutritional values of 14 alfalfa varieties were investigated in the experimental field by method of randomized block test . The results showed that the plant height of ‘Golden Empress’ and ‘WL319HQ’ were significantly higher than that of alfalfa varieties,and its growth rate and growth ability were higher than others varieties; the total biomass of ‘Golden Empress’ and ‘Zhongcao No.5’ were higher than that of ‘Shanbei’; CP values of 14 alfalfa varieties were all higher than 17.0%,and this indicated that all alfalfa varieties could reach the standard of first class forage,and the RFV values in ‘Shanbei’ alfalfa was lower than other alfalfa varieties. In conclusion,‘Golden Empress’ ,‘Empress’,‘Zhongcao No.5’ and ‘Gannong No.3’ had good palatability and were advantageous to be extended in the farming pastoral area of Northern Shaanxi.
