摘　　要：针对葛根生产中苗木混乱、成活率低的问题,进行不同品种、不同育苗方法及其对苗木移栽成活率影响研究。结果表明:QS08-1、赣葛1号葛头育苗发芽率均在90%以上,不同品种同一部位发芽率无差异,而老枝发芽率达88%以上,比中老枝高50%以上,比嫩枝高70%以上;赤霉素、吲哚乙酸、萘乙酸处理相同部位发芽率差异不显著,与对照差异均达极显著;葛头苗移栽成活率达97.33%;老枝扦插苗成活率达77%,比压条苗高46.44%,中老枝成活率41.67%,比压条苗高11.11%,嫩枝苗成活率为2.78%,比压条苗低27.78%。不同品种压条出苗率均在98%以上,而移栽成活率只有30.56%。表明葛头苗和老枝扦插苗出苗率高,移栽成活率也较高。This study aimed to investigate the relationship between survival rate of seedling and different nursery techniques in Radia Puerariae.The results showed that germination rates of QS08-1 and Gange 1 was up to 90%,there was no difference in the same position of branch germination rate of elder branches was up to 88%,which was 50%higher than adult branch,and 70%higher than young branch.There was no difference on germination rate treatmented by gibberellin,indole acetic acid,naphthalene acetic acid,but there was a significant difference between treatment and control.The survival rate of transplanted seedling was 97.33%,the survival rate of elder branches cottage seedling was 77%,46.44%higher than that of the layering seedling,and the survival rate of adult branches cottage seedling was 41.67%,11.11%higher than that of the layering seedling,and 2.78%of young branch currage seedlings,27.78%lower than the control.The seedling emergence rate of different cultivars was more than 98%,the survival rate of transplanted seedling was only 30.56%.Our results indicate that the seedling rate of Radix Puerariae and the cuttage seedling of elder branch was high,with higher survival rate transplanted seedling.
