摘　　要：通过5 a的耕地土壤定位监测结果表明,在常规施肥和管理水平条件下,各个监测点的土壤养分平衡状况是氮磷有盈余而钾亏缺严重。今后应调整施肥结构,稳氮、控磷、增钾,以有机肥为主,有机无机结合,培肥地力。Cultivated soil in Quanzhou City had been monitored for 5 years. The results showed that applying fertilizer with the routine management, caused the surpluse of nitrogen, phosphorus in the soil but the potassium lost seriously. Fertilizer-Applying structure needs to be adjusted to steady nitrogen fertilizer, control the phosphorus fertilizer, increase the potassium fertilizer, rely mainly on the organic fertilizer.
