| 中文摘要: |
| 通过对12个国内外紫花苜蓿品种的地上生物量、地下生物量以及水分利用效率的比较研究,运用聚类分析法分析了不同苜蓿品种在渭北旱塬丘陵沟壑区的适应性。结果表明,品种间地上生物量、地下生物量、水分利用效率差异明显。巨人、西河的地上生物量显著高于其它9个品种;WL-323ML、西香、苜蓿王、巨人的地下生物量显著高于其它品种;而从水分利用效率看,较高的是苜蓿王、巨人、西河。聚类分析结果表明,苜蓿王、西香和巨人较其他9个品种在渭北旱塬丘陵沟壑区的整体适应性好,适宜大面积种植和推广。 |
| 英文摘要: |
| On basis of the comparison of above-ground biomass, underground biomass and water use efficiency, the adaptability of twelve introduced and local alfalfa cultivars in the hilly and gully regions of Weibei Plateau was studied by using cluster analysis. The results showed that there were distinctly differences among alfalfa cultivars in the above-ground biomass, underground biomass and WUE. The above-ground biomass of Giant and Siriver was significantly higher than that of other cultivars, while the underground biomass of WL-323ML, Cimmaron, Emperoer and Giant was significantly higher than that of other cultivars. As for WUE, Emperor, Giant and Siriver were relatively superior. The results of cluster analysis indicated that Emperor, Giant and Siriver were generally suitable to Weibei Plateau and could be planted in large scale. |
