摘　　要：本文对不同类型的水稻土壤的供氮特征进行了研究。研究认为，水稻土壤的氮素矿化和水稻的吸氧量与产量关系密切。以施肥来协调水稻土壤供氮量和水稻需氮量之间平衡，可以使水稻稳产高产。Nitrogen supplying characteristics of different types of rice soil were studied.It showed,there were close relation between nitrogen mineralization and nitrogen absorbing. Coordinating the balance of nitrogen supplicattion and nitrogen requirement by fertilizing made the rice yield stable and high.
