Abstract：In order to investigate the application method of nitrogen in the process of planting adzuki bean, field experiments were conducted to study the effects of N fertilizer application patterns and nitrification inhibitor( NI) on growth and N utilization of adzuki beans. The results showed that the dry and fresh weight of plant,N accumulation and yield of adzuki beans treated with topdressing fertilization increased by 2. 7%,3. 7%,5. 6%,1. 9% compared with those of the base-fertilizer treatment respectively. And the difference of fresh weight, yield and N accumulation were significant. The apparent utilization efficiency, agronomic efficiency, physiological efficiency, yield contribution rate increased by 7. 4%, 23. 6%,15. 6% and 17. 2% respectively. Compared to the treatment without NI,the combination of NI with urea as base fertilizer could increase the plant fresh and dry weight,yield and accumulation of N by 2. 8%,10. 1%,6. 8% and 6. 9% significantly. The apparent utilization efficiency,agronomic efficiency,physiological efficiency, yield contribution rate increased by 26. 6%, 28. 5%, 1. 9% and 20. 1%respectively( except the fresh weight) . But no obvious difference was observed between the two treatments of topdressing N fertilizer with NI and without NI. Therefore,the topdressing N fertilizer was recommended under the condition without NI,and the base fertilization was recommended under the condition with NI.
