青海省同德高寒牧草良种繁育基地建设初报

以青海省同德高寒牧草良种繁育基地的4种牧草为研究对象,分析了多叶老芒麦、短芒老芒麦、中华羊茅和冷地早熟禾在高寒地区的幼苗建成、越冬率、平均株高和种子前3年的种子产量。结果表明,作为高寒地区的种子繁育牧草种,多叶老芒麦和短芒老芒麦比其他2个草种具有更大的优势。最后,讨论了在高寒地区建设牧草良种繁育基地的意义,并对以后该区的牧草良种繁育基地建设提出了一些建议。

Preliminary Report on the Construction of Fine Species Breeding Base of Alpine Forage in Tongde Area of Qinghai Province

With 4 species of forage in fine species breeding base of alpine forage in Tongde area of Qinghai province as studying objects,the seedling forming,winter survival rate,average plant height and seed output in the first 3 years of Elymussibiricuscv duoye,E.breviaristatum,Festuca arundinacea and Poaannua in alpine region were analyzed.The results showed that as forage specie of seed propagation,E.duoye and E.breviaristatum had bigger advantages than the other 2 grass species.Finally,the sense of establishing fine species breeding base of forage in alpine region was discussed,and some suggestions were put forward for the construction of fine species breeding base of forage in the region in future.
