不同氮肥和磷肥用量对小麦产量的影响分析

当前合理控制化肥用量已然成为农业发展的必经之路，为了有效减少化肥用量、提高地力水平、增加作物产量，此次研究针对不同氮肥和磷肥用量对小麦产量的影响，进行了深入的探究。研究中采用田间裂区试验，分析了不同绿肥品种下氮肥与磷肥用量对小麦产量等指标造成的影响。结果显示，绿肥混播条件下对氮磷肥料分别减施至120kg N/hm2与80kg P2O5/hm2时，小麦可达到其产量的最高值，这表明该种施肥处理方式具有较好的应用效果与应用价值，可在农业生产中进行大力推广。

Effects of Different Amounts of Nitrogen and Phosphorus Fertilizer on Wheat Yield

At present, reasonably controlling the amount of chemical fertilizer has become the only way for agricultural development. In order to effectively reduce the amount of chemical fertilizer, improve the soil fertility level and increase crop yield, this subject makes an in-depth study on the impact of different amounts of nitrogen and phosphorus fertilizer on wheat yield. Field split plot experiment was used to analyze the effects of nitrogen and phosphorus fertilizer on wheat yield under different green fertilizer varieties. The results showed that when the nitrogen and phosphorus fertilizer were reduced to 120kg n / hm2 and 80kg P2O5 / hm2 respectively, the wheat yield could reach the highest value, which showed that this fertilization treatment had good application effect and value, and could be popularized in agricultural production.
