在多年开展测土配方施肥补贴项目实施及利用耕地地力评价成果的基础上，提出可操作性强的耕地地力评价成果利用模式：利用耕地地力评价成果中的土壤养分测试数据和肥料田间试验数据建立粮食、蔬菜和大宗特色农作物测土配方施肥技术指标体系；利用耕地地力评价成果，提出不同农作物的适宜种植区、土壤类型、土壤养分、大权重评价因子及主要改良方向；利用测土施肥配方技术指标体系中的产量回归方程估算主要农作物的产量。因此，利用地力评价系统提供的土壤有效养分测试数据和空间数据，扩大了农作物施肥指标体系的使用范围，提高了应用的可操作性和智能化程度；利用农作物施肥指标体系提供的施肥数学模型，地力评价系统可对规划的农作物进行目标产量的估算，提高了地力评价系统评价内容的准确性。

On the basis of carrying out soil testing and formulated fertilization subsidy programs implementation and using farmland productivity evaluation results for years ,feasible utilization models of farmland productivity evaluation results were put forward:using soil nutrient testing data and field fertilizer experiment data of farmland productivity evaluation results ,the technical index system of soil testing and fertilizer recommendation of grain,vegetables and staple crops were established;farmland productivity evaluation results were also used to put forward suitable planting district ,soil type,soil nutrient,major evaluation factor and modified direction of different crops;using yield regression equation of the technical index system of soil testing and formulated fertilization ,yields of staple crops were estimated.Therefore ,through using the soil available nutrients test data and spatial data from soil fertility evaluation system ,usable range of crops fertilization index system was extended ,operability and intelligent degree were increased;using fertilization mathematical model from the crops fertilization index system ,target yield of crops can be estimated through soil fertility evaluation system,accuracy of evaluation content of soil fertility evaluation system was also improved.
