-
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。Abstract: 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.
