| 摘 要： | 针对拉萨河谷的自然气候条件, 选择了9种三叶草品种进行集中品比试验, 观察各种牧草的越冬率、生育期、高生长速率和产草量等生产形状。结果表明, 拉萨河谷下游河谷区适合引种栽培三叶草，三叶草能够顺利越冬，能够取得与其它地区相似气候条件下的相当产量。在参试品种中，Zgrk8802 红三叶、Beskyd红三叶和Vesna 红三叶是适宜于拉萨河谷下游的优良牧草品种，在越冬率、产草量、生长期和生长速率方面表现都是优良的品种，值得在拉萨河谷下游区推广。

| Abstract: | According to biophysical condition of Lhasa River Valley, 9 varieties of clover were introduced to the area for growth performance comparison. Indicators including percentage of living through winter, growth period, high growth rate and forage production were measured and compared. Lhasa river valley is suitable for clover forage cultivation. Clover can survive through winter and reach corresponding forage production compared with similar climate conditions in other places. Zgrk8802 clover, Beskyd clover and Vesna clover are the most suitably introduced varieties in terms of winter survival rate, forage production, growth period and growth rate for cultivation in the lower reaches of Lhasa River Valley. |
