笔者比较了10个紫花苜蓿(Medicago sativa L.)品种在黑龙江地区的表现。结果表明,参试各品种青干草产量存在显著差异,茎叶比有显著差异,而鲜干比无显著差异;生长速度与产量呈正相关关系。龙牧系列品种和肇东苜蓿适应性均较强,适合在北方寒冷的地区种植。
The author compared the performance of 10 alfalfa (Medicago sativa L.) cultivars in Heilongjiang. The results showed that there was a significant difference in the yield of green hay between the tested varieties. The ratio of stem to leaf was significantly different, while the fresh-dry ratio was not significantly different. The growth rate was positively correlated with the yield. Longmu series of varieties and Zhaodong alfalfa adaptability are strong, suitable for planting in the northern cold areas.
