Abstract
The nutrient' s uptake characteristics of rice and application methods of nitrogen fertilizer were studied in 1996-1999. The results showed that:The N uptake characteristics of rice were influenced remarkably by application methods of N fertilizer under other conditions identical.When part of N fertilizer was applied at middle growth stage, the amount N absorbed was more and the heavy absorb period was longer, the yield was higher and the N use efficiency was higher than the treast-ment of all N applied as basal fertilizer.
