[The research of technique of Panax notoginseng seed coating for culturing seedlings]

To screen seed coating formulation and to investigate culturing seedling technique for Panax notoginseng (Sanqi).

Fungus check for the seeds in room and study on medicament disinfecting effect were carried out to obtain three optimum seed coating formulation. In contrast with routine medicament immersing seed and blank test, the effects of different seed coating formulation, rate between medicament and seed, and coating time were studied on nursery rate, yield and quality of Sanqi.

The different seed coating formulation had evident difference on Sanqi. Concentration of seed coating formulation and coating time notably affected nursery rate and yield of Sanqi.

The optimum method is using No. SQ2 seed coation formulation in the rate 1:50 between medicament and seed, and coated one or two days before sowing.
