本研究在分析苏南农村工业化地区农田施肥制发展变化的基础上，对该地区不同时期出现的农田施肥制度（施肥水平和施肥结构），在现有生产力水平下进行了田间模拟试验，以探讨农田生产力持续提高的合理施肥制。试验结果表明在现有生产力水平下，采取低投入以有机肥为主的施肥方式是没有出路的，只能带来农田生产力的下降和土壤肥力的衰减，而采取高投入以化肥为主的施肥制，也不利于农田生产力的持续提高。只有在较高的投入水平条件下，有机与无机肥、氮磷钾合理施用，才能持续提高作物生产力和保持土壤肥力。
Based on the analysis of the development of farmland fertilization system in the rural industrialized areas of southern Jiangsu province, the field fertilization system (fertilization level and fertilization structure) appeared in different periods in this area were simulated in the field of existing productivity to discuss Farmland productivity continued to improve the rational fertilization system. The results show that under the current level of productivity, adopting low input organic manure-based fertilization is not a way out, which can only bring about the decline of farm productivity and soil fertility. However, high-input fertilizer-based fertilization System is not conducive to the continuous improvement of farm productivity. Only under the condition of higher input level, organic and inorganic fertilizers, NPK can be rationally applied to continuously increase crop productivity and maintain soil fertility.
