以山东省粮食主产区平原县的142户农户为调查对象，详细调查了当地小麦玉米轮作模式下的施肥情况。结果显示，当地农业生产中存在有机肥施用偏少，化肥投入量过大，氮肥比例偏高，钾肥比例偏低的问题。农户对于肥料的施用方式比较简单粗放。化肥过量施用和养分偏施会导致养分流失和肥料利用率的下降，带来生态环境问题，文中简要分析了施肥现状、存在的问题，并据此提出了相应的对策建议。%To understand the fertilization situation under wheat-maize rotation mode in major grain pro-ducing area of Shandong, 142 farmers from Pingyuan were investigated in this study.The results showed that there were many problems such as fewer organic fertilizer application amount, excessive chemical fertilizer in-put, higher N fertilizer ratio and lower K fertilizer ratio.At the same time, the fertilization manners were sim-ple and extensive.Excessive chemical fertilizer application amount and prejudiced nutrient would cause nutri-ent loss and the decline of fertilizer use efficiency, which could bring many ecological and environmental prob-lems.The fertilization situation and problems were briefly analyzed in this study and corresponding counter-measures and suggestions were put forward.
