Abstract: The utilization of controlled-release fertilizer can improve crop nutrient uptake and fertilizer utilization efficiency. The design of controlled-release fertilizer should be based on the characteristics of crop nutrient uptake. In this paper，the nitrogen uptake accumulation of main crops were analyzed to be a “S”pattern and could be divided into seedling，vegetative and reproductive three periods. An ideal cumulative release curve of film coated controlled-release fertilizers should correspond with this “S”pattern，i.e. a mode of lagging，constant rate and decayed periods. For the match of fertilizer controlled release and crop nitrogen uptake，performance design for controlled-release fertilizer is suggested. For crops with a long growing period of passing winter，the release should be controlled with 20% in lagging of 120 to 150 days，55% in constant rate period of about 60 days，and 25% in decayed period of about 30 days. For corps with life of 90～130 days，the release should be controlled with 5% in lagging of 20 to 30 days，80% in constant rate period of 30 to 60 days，and 15% in decay period of about 30 days. For vegetative harvest of vegetables，the release should be controlled with 5% in lagging of about 20 days，and 95% in constant rate period of about 40 days.
