在其他条件相同的情况下，通过减少化肥用量，改进施肥方法，探讨了化肥减量增效技术的效果。结果表明，减肥10%的处理产量最高，正常施肥处理其次，减肥20％的处理第3；正常施肥与减肥10%～20％的处理产量差异不显著，其他处理随着化肥用量的减少产量随之减少；化肥与稻谷的投入产出比随着化肥用量的减少而增大。所以通过改进施肥技术，水稻生产实现化肥减量增效是可行的。

A field experiment was carried out to explore the effects of fertilizer reduction technology on growth eharacters and yield of rice in this study. The results showed that the yield decreased with the decrease of fertilizer. The yield was highest when the amount of fertilizer was reduced by 10%, the yield of conventional fertilization treatment was the second. There were no significant difference in yield between conventional fertilization and fertilizer reduced by 10% to 20% treatments. The input-output ratio was increased with the decrease of fertilizer. Therefore, it is feasible to application the technology of fertilizer reduction in rice production.
