Abstract: The paddy planting manners include direct seeding and mechanical transplanting. According to the characteristics of seeding quality detection technique, there are dynamic monitoring for the metering device performance and static detection for seeds planted in plugs. Dynamic monitoring technology was applied to detect seeding quality of direct seeding, and static detection technology was applied in mechanical transplanting. The main methods of dynamic monitoring and static detection for the paddy seeding quality were suggested, and the main problems existing in the development of the seeding quality detection were discussed. Due to the technology of paddy seeding quality detection was at the level of manpower, the potential methods for the paddy seeding quality detection and the further research approaches were proposed．
