The effects of different paddy field drainage degrees including three soil water levels (0-20 cm soil volumetric water content was controlled at 53.60%±5.00%, 40.20%±5.00%, and 26.80%±5.00%, indicated by W1, W2, and W3 respectively) and three panicle nitrogen fertilizer managements (the panicle nitrogen fertilizer was applied on the 1st, 8th, and 15th day after rewatering, indicated by N1, N2, and N3 respectively) on dry matter productivity, nitrogen accumulation, translocation and utilization and yield of rice were investigated with nitrogen efficient variety(Dexiang 4103) and nitrogen inefficient variety(Yixiang 3724). The results showed that proper paddy field drainage degree could increase dry matter accumulation and translocation, nitrogen accumulation, translocation and utilization and yield of rice, and there are different effects for panicle nitrogen fertilizer management on yield and nitrogen utilization efficiency of different nitrogen efficiency rice. The dry matter accumulation and translocation, nitrogen accumulation, translocation and utilization of the nitrogen efficient variety were obviously higher than that of the nitrogen inefficient variety; the average yield of the nitrogen efficient variety was 1.12 t/hm2 higher than that of the nitrogen inefficient variety. Yield of nitrogen efficient variety and nitrogen inefficient variety had strongly positive correlation to dry matter accumulation and translocation and total nitrogen accumulation; yield of nitrogen efficient variety had strongly positive correlation to nitrogen translocation amount of stemsheath and yield of nitrogen inefficient variety had strongly positive correlation to nitrogen translocation amount of leaf and stemsheath. By applying the panicle nitrogen fertilizer on the 15th day after rewatering for nitrogen efficient variety (Dexiang 4103) under proper paddy field drainage condition treatment (W1) and applying the panicle nitrogen fertilizer on the 8th day after rewatering for nitrogen inefficient variety (Yixiang 3724) under proper paddy field drainage condition treatment (W2), nitrogen utilization efficiency and grain yield were all increased.
