| 摘 要： | 通过对紫花苜蓿、鹰嘴紫云英、红豆草、百脉根越冬前后形态、生理指标比较,研究4种豆科牧草抗寒能力。结果表明,各牧草的抗寒性能与牧草的根茎直径、越冬芽数量呈显著正相关。最后通过对各牧草各项指标作出了综合性价:紫花苜蓿、百脉根抗寒性能明显高于红豆草和鹰嘴紫云英,同时提出可溶性糖含量可作为几种牧草在本区的鉴定指标。

| Abstract: | Characters of cold resistance of four leguminous forage species have been studied based on morphological and physiology parameter before and after over-wintering.The results showed that the cold resistance of leguminous forage was significant correlation to root diameter and winter bud numbers.Comprehensive analysis indicated Medicago sativa and Loteae corniculatus were more cold resistance than Astragalus sinicus and Onobrychis viciifolia.Soluble sugar content can be as identification indices in valuing re... |
