青海高寒区不同红豆草种质资源生产性能与适应性对比研究
A Comparative Study of the Production Performance and Adaptability of Different Red Bean Grass Germplasm Resources in the Cold Region of Qinghai
摘要
Abstract
To screen superior germplasm of sainfoin(Onobrychis viciaefolia)suitable for cultivation in Qinghai's high-altitude,semi-arid regions,this study compared key traits among five sainfoin germplasm resources.Using Qingyu No.1,Qingyu No.2,HD8630,HD9245,and Mengnong as materials,germination rates,agronomic traits,and yield performance were measured in Tongde County.Results showed Qingyu No.1 exhibited the highest germination rate(92.33%)and significantly outperformed other germplasm in plant height(86.67 cm),number of branches(17.33),and primary root diameter(1.03 cm)(P<0.05).Its fresh and dry forage yields were also significantly higher than other materials.In summary,Qingyu No.1 exhibits strong adaptability and high yield potential,making it suitable as the primary recommended sainfoin germplasm for Qinghai's high-altitude cold regions.关键词
