摘　　要：选取禹城市粮食良种场固定地块,从2016年开始连续5年定位监测冬小麦产量与土壤肥力指标,为监测农田土壤质量变化提供依据。结果表明:2016—2020年冬小麦产量逐年增加,增幅为22.5%;土壤有机质和全氮含量呈逐年增加趋势,增幅分别为16.4%,32.0%,土壤有效磷和速效钾含量呈逐年提升趋势,增幅分别为54.5%,22.4%。研究结果将为该区域冬小麦产量稳步增加、土壤培肥提供基础数据。In order to monitor the change index of farmland soil quality,the location plot of Yucheng farm was selected in the experiment,and the winter wheat yield and soil fertility index were monitored for five consecutive years from 2016.The results showed that:from 2016 to 2020,winter wheat yield increased by 22.5%;soil organic matter and total nitrogen content increased by 16.4%and 32%,respectively;soil available phosphorus and available potassium content increased by 54.5%and 22.4%,respectively.The results would provide basic data for the steady increase of winter wheat yield and soil fertility in this region.
