摘要
2005年,在云南海拔1600 m的亚热带高湿地区,对12个柱花草品种进行了引种试验并用灰色关联分析法对牧草的适应性、地上生物量、茎叶比、青干比、分枝数、株高等指标进行综合评价。结果表明:柱花草是适合亚热带高湿地区栽培的优良草种,其中CIAT11362柱花草综合性能最优,可作为当地的推广品种。此外,R93柱花草、热研13号柱花草、GC1579柱花草、GC1463柱花草、热研5号柱花草、GC1581柱花草的综合性能也显著高于其他品种,应根据当地的不同利用方式选择使用。
Comparison of 12 introduced varieties of Stylosanthes guianensis was carried out in the area with the altitude of 1600 m in Yunnan Province, 2005. The index relating the adaptability, yield, stem-leaf ratio and fresh-dry ratio, ramification number and plant height were measured. And the comprehensive evaluation was made by using grey relation analysis. The results showed that Stylosanthes guianensis adapted the subtropical humid conditions. CIAT 11362 was the best variety for widely utilizing in this area because of its highest evaluation score. Varieties including R93 ,Reyan No. 13,GC 1579,GC 1463 ,Reyaln No. 5 and GC 1581 shown excellent performance among 12 tested varieties and could be selected for different utilization.
