| 摘 要： | 以河北雄县长期定位耗竭试验为材料，研究了该区当前高产技术水平条件下，在小麦和玉米两种作物上土壤各种养分的支撑产量，通过支撑产量得到土壤养分限制谱序及外源可调度，据此提出了随着作物产量的进一步提高需要补充养分的先后顺序和营养元素组配方案。为指导平衡施肥和肥料资料的配置计划及预测提供了科学依据。

| Abstract: | The effect of soil nutrients on the sustaining yi eld of wheat-corn was studied i n this paper based on the field depletion experiment in Xiongxian county of Heb ei province In the meantime, the order of soil nutrient limiting factors and y ield exogenous regulating range were observed According to the order of soil n utrient limiting factors and exogenous regulating range, the order of supplement ary nutrients needed and the nutritional elements allocation plan were put forwa rd with the yield increasingly further It provided a foundation for the balanc ed fertilization plan and fertilizer source allocation project |

| Keywords: | sustaining yield the order of soil nutrient limiting factors exogenous regulating range allocation plan |
