水稻氮肥农学利用率分析数据

将不同量的氮肥施用于水稻上，研究不同施肥方法对水稻氮肥农学利用率的影响，探索水稻种植中最优施氮量。水稻周年纯氮施用量为420 kg/hm2，不施肥空白区水稻周年产量为10244.98 kg/hm2，将施氮区水稻周年产量为a，施氮量为b，氮肥农学利用率为c，则c=（a-10244.98）/b，最终可得出不同施肥处理下水稻的氮肥农学利用率。

Different nitrogen fertilizer rates were applied to rice to study the impacts of different fertilization regimes on rice's agronomic nitrogen use efficiency and explore the optimal nitrogen application rate for rice cultivation. The annual pure nitrogen application rate for rice is set at 420 kg/hm². The annual rice yield in the non-fertilized blank control plot is 10244.98 kg/hm². Let the annual rice yield of nitrogen-fertilized plots be a, the nitrogen application rate be b, and the agronomic nitrogen use efficiency of the nitrogen fertilizer be c; then c = (a - 10244.98)/b. Finally, the agronomic nitrogen use efficiency of rice under different fertilization treatments can be calculated.
