摘要
针对高寒地区草地退化、豆科牧草缺乏的现状,于2004-2007年在海拔3 050 m的甘肃高寒地区夏河县开展了连续4年的甘肃红豆草(Onobrychis viciaefolia cv. Gansu)适应性试验研究,并对其物候期、株高、产草量、越冬率等指标进行了综合评价,结果表明甘肃红豆草在海拔3 000 m左右的高寒牧区,建植后连续3年种子均发育成熟,4年中产草量和越冬率逐年增高,各种性状表现良好,可以作为优质豆科牧草在高寒地区推广种植。
Aimed to the situation of grassland degradation and lack of legume in alpine region,the adaptability of Onobrychis viciaefolia cv.Gansu was studied in the area with 3 050 m of altitude of Xiahe County,the alpine region of Gansu Province from 2004 to 2007 by measuring the growth periods,plant height,grass yield and overwintering rate.The results showed that the ripe seeds could be obtained,its grass yield and overwintering rate increased along with the growth time.It could be extended in alpine region as a high quality legume.
