| 摘 要： | 通过对4个紫花苜蓿品种大田栽培试验,并利用相关分析和通径分析方法对其生长性状进行统计分析。结果表明:生长性状中叶重对提高紫花苜蓿粗蛋白最为重要,茎重和主茎直径对增加紫花苜蓿干物质产量有较大的作用,株型较矮且茎粗者抗倒伏力强。结论:生产优质高产紫花苜蓿需选择叶量丰富、茎粗壮且株型较矮的品种。

| Abstract: | Cultivate 4 alfalfa varieties,growthtraits were statistical analysis by correlation analysis and path analysis,the results indicate that the leaf heavy is the most important to the crude protein,stem heavy and main stem＇ diameter are the most important to the dry matter（MD） yield.The plant shape low and stem brawny are of the strong resistance.Therefore,the alfalfa varieties be of abundance leaf and plant shape low and stem brawny are important in product fine quality alfalfa. |
