[Objective]The aim was to explore cultivation method of quality and high production for Platycodon grandiflornu. [Method]Compared root main agronomic characters under topsoil depth of 15, 20, 30, 40 cm and no fertilization, full-thickness fertilization, deep fertilization (30-40 cm). [Result]On experiment of topsoil depth, the main root length in 30 cm depth was the longest, root diameter was the widest, single root fresh weight was the heaviest, however, the lateral root also had the largest number. In the fertilization, the effects of deep fertilization was better than full-thickness fertilization and no fertilization. [Conclusion]The results of the experiment has certain reference value for establishment of mountains, mid-levels P. grandiflornu cultivation system.
