摘　　要：[目的]筛选海南肾茶繁殖的最佳方法。[方法] 通过压条、分株和扦插3种方法繁殖海南肾茶，探讨这3种繁殖方法的效果。[结果] 扦插繁殖、分株繁殖和压条繁殖3种方法均能使海南肾茶成功繁殖，其中分株繁殖是保证材料安全的有效措施之一，压条繁殖可以较快地提高海南肾茶的繁殖数量，扦插繁殖是满足产业化生产育苗的最佳方法。扦插繁殖的材料为5-12个月的茎干。在保持土壤湿度和适当光照的情况下，扦插繁殖的材料存活率高，生长速度快，20d后就可以进行大田栽培，海南全年均可繁殖，但在12月份最佳。[结论]该研究为海南肾茶的繁殖及其产业化育苗奠定了基础。[ Objective ] The aim was to screen the optimum propagation method for Clerodendranthus spicatus in Hainan. [ Method ] 3 propagation methods of laying propagation, division propagation and cutting propagation were used to propagate C. spicatus and the effect of 3 propagation methods were discussed. [ Result] 3 propagation methods of cutting propagation, division propagation and laying propagation all could make Hainan C. spicatus propagate successfully. Among them, division propagation was one effective measure for guaranteeing materials safety. Laying propagation could increased the propagation amount of C. spicatus in Hainan and cutting propagation was the optimum method for meeting the industrial production and seedling. The materials of cutting propagation was 5 - 12 month caudex. Under conditions of keeping soil humidity and proper illumination, the survival rate of materials with cutting propagation was high, growth speed was fast and they could be taken for field cultivation after 20 d. They could propagate in the whole year in Hainan, but December was the optimum time. [ Conclusion] The research laid the foundation for the propagation and industrial seedling of Hainan C. spicatus.
