旱作条件下苜蓿品比试验及主要性状分析

Comparative Experiment of Alfalfa Varieties Cultivated Without Irrigation Conditions and Analysis of Their Major Characters

本项研究对3个国内苜蓿品种、14个国外苜蓿品种的产量性状进行了田间观测和统计分析。结果表明国内苜蓿品种的生产性能要优越于国外品种,国外苜蓿品种的再生能力则优于国内品种,株高、枝条密度、枝条直径均与产量相关。

Some characters of fourteen abroad alfalfa varieties and three domestic alfalfa varieties were determined and analyzed in the paper. The results of this study showed that the ability of production of the domestic varieties was better than abroad ones, but the ability of re-production of abroad varieties was better than domestic varieties. Plant height, the branch diameter and the density of the branch were correlated to the yield.
