Abstract: This paper studied on the difference of a shallow liquid culture system and the solid culture system in the system of rapid propagation technology of virus-free ginger. The multiplication coefficient、the length of root and plant height in shallow liquid culture were prior to those of solid culture. As the regeneration frequency of root and the average root number of each explant were analyzed, there was no significant difference between the two systems. The survival rate of transplantation of seedlings from the shallow liquid system was much higher than that from solid culture system. Furthermore, the cost of chemicals of shallow liquid system was only less than 1/3 compared to that of solid system. Meanwhile, the load of manual work and time were reduced much more. So it was more economical and convenient. For all of the above, the shallow liquid culture system was proposed during rapid propagation process of virus-free ginger.
