摘要： 为了解不同水稻配方复合肥在籼粳杂交稻（‘甬优12’）上的化肥减量增效效果，选择当地常用的4种水稻配方复合肥，以常规施肥为对照，在化肥总养分均减少10.2%的条件下，探索其对水稻的节本增效。结果表明：综合水稻生育表现、经济性状及产量，施用水稻配方专用肥(16-10-14)，水稻生育表现佳，化肥成本减少16.90%，增产1.76%，对水稻化肥减量增效效果最好，适合在当地进行推广应用；施用复合肥(20-12-14)，水稻综合表现次之，节本增效效果不显著；施用复合肥(22-6-12)，水稻综合表现较差，节约的肥料成本不抵减产产值；施用复合肥(15-10-17)，水稻综合表现最差，肥料成本上升，产量也下降。

Abstract: To investigate the effects of fertilizer reduction and efficiency increase of different formula fertilizers on indica-japonica hybrid rice ‘Yongyou 12’, under the condition of total chemical fertilizer decreased by 10.2%, four formula fertilizers were used as materials, and conventional fertilization was used as CK. The results showed that: rice specific fertilizer (16-10-14) was the best practice with fertilizer cost reduced by 16.90% and rice yield increased by 1.76%, so it was suitable for promotion and application in this area. Then was compound fertilizer (20-12-14), the effect of fertilizer reduction and efficiency increase was not obvious. Compound fertilizer (22-6-12) could save fertilizer cost, but the rice yield decreased. Compound fertilizer (15-10-17) not only raised fertilizer cost, but also reduced rice yield.
