摘　　要：[目的]为匙羹藤在桂林的栽培管理工作提供有价值的参考。[方法]对桂林地区引种栽培的匙羹藤进行低温适应性观测,采取不同管理模式与防寒措施进行比较试验。[结果]试验结果表明:匙羹藤生长苗龄短相对生长苗龄长的受冻要严重;采取不同防寒措施中铺盖稻草的匙羹藤抗寒性优于对照;不同栽培环境中匙羹藤受寒害由轻到重的是大棚内栽培>林缘栽培>盖50%遮阴网栽培>大田栽培;实生苗抗寒性大于扦插苗。[结论]科学管理措施是匙羹藤在桂林地区越冬的必要条件。[Objective] The aim of the research was to provide references for the cultivation management of Gymnema in Guilin.[Method] The low temperature adaptability of introduced Gymnema in Guilin was investigated.Different management modes and winter-proof measures were compared with relative experiments.[Result] The experimental results showed that young seedlings were damaged badly than old seedlings.The damage of Gymnema with different winter-proof measures was slight than CK.The sequencing of damages of Gymnema under different cultivation circumstances was cultivation in shed〉 cultivation in forest edge〉50% shading cultivation〉field cultivation.The cold resistance of seedlings was higher than cutting seedlings.[Conclusion] Scientific management was the necessary condition for Gymnema in winter.
