摘要
在吉林省农业科学院牧草试验地内对来自欧洲的8个苜蓿Medicago stiva品种进行了田间比较试验,对于不同紫花苜蓿品种的生长速率、自然高度、分枝数、干草生物量和其他生长发育特性进行了比较。分析结果表明:8个紫花苜蓿品种在生长发育特性上存在显著的差异,其中表现好的是蒂坦、罗佐马、伊鲁瑰斯、凯恩4个品种,他们的优势是返青早,生长速度快。蒂坦、罗佐马产草量高;蒂坦、凯恩粗蛋白含量高,营养价值较高。蒂坦、罗佐马、伊鲁瑰斯和凯恩适宜在吉林地区大面积推广和种植。
A field comparative test of 10 alfalfa varieties introduced from Europe and domestic was carried out in Jilin Forage Experimental Station of Academy of Agricultural Sciences of Jilin Provience. The characteristics including growth rate, natural height, tiller number, fresh yield were tested. The results showed that there were significant differences in characteristics of growth and development among 8 varieties. The foreign varieties, including Titan, Luozuoma, Roquois and Kane had better performances and their yields were high. Meanwhile, they showed early regreenning and faster growth. In which, the yields of Titan and Luozuoma were higher. The crude protein content of Titan in the squaring stage was the highest and the second was Kane. It could be concluded that these 4 varieties were suitable for extension in Jilin Province.
