摘　　要：为了解不同施氮量对大豆产量及经济效益影响,文章设置不同氮肥施用量,对商丘永城市裴桥镇试验地大豆产量及经济效益进行分析。结果表明,施氮肥较不施氮肥增产效果显著,经济效益提高。随着氮肥用量增加,产量和经济效益均呈递减趋势。当氮肥用量为105 kg/hm^(2)时大豆产量和经济效益最高,此时大豆产量可达5131.5 kg/hm^(2),较对照增产64.16%,增收9633.6元/hm^(2)。In order to understand the impact of different nitrogen application rates on soybean yield and economic benefits,the article set different nitrogen fertilizer application rates and analyzed the soybean yield and economic benefits of the experimental site in Peiqiao Town of Yongcheng City in Shangqiu.The results showed that applying nitrogen fertilizer had a significant increase in yield and economic benefits compared to not applying nitrogen fertilizer.As the amount of nitrogen fertilizer increased,both soybean yield and economic benefits showed a decreasing trend.When the nitrogen fertilizer dosage was 105 kg/ha,the soybean yield could reach 5131.5 kg/ha,an increase of 64.16%compared to the control,and an increase of 9633.6 yuan/ha in income.
