| 摘 要： | 施肥是保证作物增产的重要措施，本研究通过田间试验分析和对比农民习惯施肥与平衡施肥的效果，并分析农民习惯施肥中盲目投肥对产量的影响。结果表明，农民习惯施肥的产量略高于平衡施肥，但未达显著水平，其纯收益却明显低于平衡施肥；平衡施肥较农民习惯增收3662元/hm2，纯收益增加40.9%。养分分析结果表明，农民习惯施肥的养分吸收量与平衡施肥的养分吸收量相当，表明农民习惯施肥中的大量养分残留在土壤中，将对生态环境造成潜在的危险。 |

| Abstract: | Fertilization is the important measure to ensure the crop yield，this study analyzed the effect of blind investment on yield in regular fertilizer, through field experiments and the comparison of the different effect of regular fertilizer and balanced fertilization. The result showed that the yield of regular fertilization is slightly higher than the balanced fertilization, but the income is significantly less than the balanced fertilization. Comparing to the regular fertilization, the balanced fertilization increased 3662yuan per Ha, net income increased 40.9%. The nutrient uptake of regular fertilization is equal to balanced fertilization of balanced fertilization, which showed that a large number of nutrient left in the soil, and will cause potential ecological risks to ecological environment. |
