对山东省不同地区1046个农户1997年施肥状况调查表明，山东省粮食作物化肥施用中存在许多不合理之处，农民偏重小麦施肥，小麦化肥氮全省平均280.0kg／hm2，有机肥氮90．4kg／hm2；玉米化肥氮208．5kg／hm2，有机肥氮33.0kg／hm2，均高于合理施氮量.计算结果表明，仅小麦超量施用化肥氮就达40万吨．合理施肥量范围内的农户比例不足20％，70％以上农户超量施肥．小麦玉米轮作周期施氮量已达到吨粮田的施氮水平，但产量只有吨粮田的70％山东省今后提高化肥增产效应需要重点解决这些问题．
The survey on the fertilization status of 1046 farmers in different regions of Shandong Province in 1997 showed that there were many unreasonable points in the application of chemical fertilizers for grain crops in Shandong Province. Farmers emphasized on wheat fertilization. The average yield of wheat chemical fertilizer was 280.0kg / hm2 and organic fertilizer was 90%. 4kg / hm2, 208.5kg / hm2 of maize chemical fertilizer and 33.0kg / hm2 of organic fertilizer were all higher than the reasonable amount of nitrogen fertilizer.The calculation results showed that only 400000 tons of fertilizer nitrogen was applied to wheat alone. Less than 20% of farmers within the reasonable range of fertilization, over 70% of farmers over fertilization. Wheat and wheat rotation cycle nitrogen application rate has reached the level of nitrogen fertilizer application, but the output is only 70% of the grain field in Shandong Province in the future to increase fertilizer production effects need to focus on solving these problems.
