Abstract: Essential factors of flower seedling industrialization were discussed in this paper. The results indicated that the problems of flower industry in Beijing were deficiency of independent intellectual flower variety, incomplete flower industrial linking, unsoundness of law and regulation, simple model of sale, imperfect system of service and standard, and deficient of production-college-research union. Strategies of developing flower seedling industry were suggested, such us reinforcing government regulation, cultivating Beijing- characteristic flower variety, refining industrial division, establishment of flower seedlings quality standard system and certification institutions, developing service system and establishing flower seedling consortium, on the base of the analysis of international flower seedling situation, in order to provide policydecision basis for flower seedling industrialization.
