| 中文摘要: |
| 研究分析了引自加拿大的3个紫花苜蓿品种在生育特性、抗病虫能力、根系发育能力、营养价值、产草量等方面与国内新疆大叶苜蓿的差异。结果表明:3个引进品种均优于对照品种,其中胜利者早熟,再生性能强,鲜,干草产量、粗蛋白含量高,营养成分丰富,生态适应性好,值得推广应用。 |
| 英文摘要: |
| The experiment was conducted in2years to evaluate the growth characteristics，resistance， root system development ability，forage yield and nutritive value of three introduced alfalfa cultivars and Xinjiang large-leaf alfalfa．The results showed that the introduced cultivars performed better in the above characteristics than that of the domestic cultivar （ CK） ，in which，the cultivar of Vector showed the advantage of early maturity，strong regrowth ability，good resistance，high fresh forage yield，high content of crude protein and strong ecological adaptability，and it was an ideal cultivar to be extended on large scale in the semi-arid areas． |
