Abstract: The experiment of controlled2release fertilizers (CRFs) on growth and development of salvia plant in pot was conducted in comparison with common compound fertilizers (CCFs) . The contents of chlorophyll , number of leaves , leaf area and growth potential of the salvia treated by CRFs were significantly greater than those by CCFs.There were higher dry matter mass and flower mass of salvia treated with CRFs compared with those by CCFs. Furthermore , the treatment with CRFs distinctly boosted florescence flourish and extended view period , which promoted salvia growth , but also avoided damage to the plants caused by excess use of fertilizers. The optimum amount for fertilizer application on salvia in the 25 cm ×21 cm pot was N 0.4 g/ kg soil .

Key words: Salvia, Controlled-release fertilizer, Common compound fertilizer, Fertilizer efficiency
